BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO THE FINANCIAL STATEMENTS

1. Organization

Boston Properties Limited Partnership (the “Company”), a Delaware limited partnership, is the entity through which Boston Properties, Inc., a self-administered and self-managed real estate investment trust (“REIT”), conducts substantially all of its business and owns (either directly or through subsidiaries) substantially all of its assets. Boston Properties, Inc. is the sole general partner of the Company and at June 30, 2007 owned an approximate 84.0% (81.4% at June 30, 2006) general and limited partnership interest in the Company. Partnership interests in the Company are denominated as “common units of partnership interest” (also referred to as “OP Units”), “long term incentive units of partnership interest” (also referred to as “LTIP Units”) or “preferred units of partnership interest” (also referred to as “Preferred Units”).

Unless specifically noted otherwise, all references to OP Units exclude units held by Boston Properties, Inc. A holder of an OP Unit may present such OP Unit to the Company for redemption at any time (subject to restrictions agreed upon at the time of issuance of OP Units to particular holders that may restrict such redemption right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, the Company must redeem such OP Unit for cash equal to the then value of a share of common stock of Boston Properties, Inc. (“Common Stock”). In lieu of a cash redemption, Boston Properties, Inc. may elect to acquire such OP Unit for one share of Common Stock. Because the number of shares of Common Stock outstanding at all times equals the number of OP Units that Boston Properties, Inc. owns, one share of Common Stock is generally the economic equivalent of one OP Unit, and the quarterly distribution that may be paid to the holder of an OP Unit equals the quarterly dividend that may be paid to the holder of a share of Common Stock. An LTIP Unit is generally the economic equivalent of a share of restricted common stock of Boston Properties, Inc. LTIP Units, whether vested or not, will receive the same quarterly per unit distributions as OP Units, which equal per share dividends on Common Stock (See Note 14).

At June 30, 2007, there was one series of Preferred Units outstanding (i.e., Series Two Preferred Units). The Series Two Preferred Units bear a distribution that is set in accordance with an amendment to the partnership agreement of the Company. Preferred Units may also be converted into OP Units at the election of the holder thereof or the Company in accordance with the amendment to the partnership agreement (See also Note 10).

All references herein to the Company refer to Boston Properties Limited Partnership and its consolidated subsidiaries, collectively, unless the context otherwise requires.

Properties

At June 30, 2007, the Company owned or had interests in a portfolio of 134 commercial real estate properties (131 and 124 properties at December 31, 2006 and June 30, 2006, respectively) (the “Properties”) aggregating approximately 42.7 million net rentable square feet (approximately 43.4 million and 42.1 million net rentable square feet at December 31, 2006 and June 30, 2006, respectively), including six properties under construction totaling approximately 1.4 million net rentable square feet, and structured parking for approximately 33,758 vehicles containing approximately 10.5 million square feet. At June 30, 2007, the Properties consist of:

 

   

130 office properties, including 109 Class A office properties (including six properties under construction) and 21 Office/Technical properties;

 

   

one hotel; and

The Company, not Boston Properties, Inc., executes all significant business relationships. All majority-owned subsidiaries and affiliates over which the Company has financial and operating control and variable interest entities (“VIE”s) in which the Company has determined it is the primary beneficiary are included in the consolidated financial statements.

On January 29, 2007, the Company acquired 103 Fourth Avenue, an approximately 62,000 net rentable square foot office/technical property located in Waltham, Massachusetts, for a purchase price of approximately $14.3 million. The acquisition was financed with available cash.

On March 30, 2007, the Company acquired Kingstowne Towne Center, a mixed-use property located in Alexandria, Virginia, at a purchase price of approximately $134.0 million. This property is comprised of two Class A office properties totaling approximately 307,000 net rentable square feet and a retail/movie theater complex totaling approximately 88,000 net rentable square feet. The acquisition was financed with the assumption of mortgage indebtedness totaling $65.3 million (see Note 5) and available cash.

On March 30, 2007, the Company acquired Russia Wharf, a land parcel located in Boston, Massachusetts, for a purchase price of approximately $105.5 million. The acquisition was financed with available cash.

Dispositions

On February 15, 2007, the Company sold the long-term leasehold interest in 5 Times Square in New York City and related credits, for approximately $1.28 billion in cash. 5 Times Square is a fully-leased Class A office tower that contains approximately 1,101,779 net rentable square feet. Net cash proceeds totaled approximately $1.23 billion, resulting in a gain on sale of approximately $736.2 million. In conjunction with the sale, the Company has agreed to provide to the buyer monthly revenue support from the closing date until December 31, 2008. The aggregate amount of the revenue support payments was approximately $1.6 million and has been recorded as a purchase price adjustment and included in Other Liabilities within the Company’s Consolidated Balance Sheets. As of June 30, 2007, the revenue support obligation totaled approximately $0.4 million. As part of the transaction, the buyer has agreed to engage the Company as the property manager for 5 Times Square for a five-year term. Either party will have the right to terminate this relationship at any time after four years upon giving the other party six (6) months advance notice. If not terminated, the agreement will automatically renew for successive one-year terms unless terminated by either party upon ninety (90) days advance notice. The Company will recognize management fees on a fair value basis over the term of the agreement. As a result, the recognized gain on sale of the property has been reduced by approximately $4.7 million, representing the difference between the management fees to be received by the Company and the fair value of the management fees. Such amount has been deferred and recorded in Other Liabilities in the Company’s Consolidated Balance Sheets and will be recognized as management services revenue over the term of the management agreement. Due to the Company’s continuing involvement through an agreement with the buyer to manage the property for a fee after the sale and the financial obligations discussed above, this property has not been categorized as discontinued operations in the accompanying Consolidated Statements of Operations (See Note 12).

On March 23, 2007, the Company sold the Long Wharf Marriott, a 402-room hotel located in Boston, Massachusetts, for approximately $231.0 million. Net cash proceeds totaled approximately $225.6 million, resulting in a gain on sale of approximately $194.4 million. This property has been categorized as discontinued operations in the accompanying Consolidated Statements of Operations (See Note 12). The sale of this property was completed as part of a “like-kind exchange” under Section 1031 of the Internal Revenue Code.

On April 5, 2007, the Company sold Newport Office Park, an approximately 172,000 net rentable square foot Class A office property located in Quincy, Massachusetts, for approximately $37.0 million. Net cash proceeds totaled approximately $33.7 million, resulting in a gain on sale of approximately $14.3 million. This property has been categorized as discontinued operations in the accompanying Consolidated Statements of Operations (See Note 12).

The Company had deferred approximately $67.3 million of the gain on sale of 280 Park Avenue, which amount represented the maximum obligation under the master lease.

“Land and Infrastructure Entity”) (a joint venture entity in which the Company owns an effective interest of approximately 23.89%) executed an amendment to its construction loan agreement. The construction financing consisted of a $96.5 million commitment, bearing interest at a per annum variable rate equal to LIBOR plus 1.50% and maturing on March 11, 2009. The outstanding balance on the construction loan was approximately $53.6 million on the $96.5 million commitment.

The Company’s share of the gain on sale has been included in Income from Unconsolidated Joint Ventures in the accompanying Consolidated Statements of Operations. In connection with the repayment of the mortgage indebtedness on the property, the joint venture recognized a loss from early extinguishment of debt totaling approximately $0.1 million, consisting of the write-off of unamortized deferred financing costs.

5. Mortgage Notes Payable

On January 9, 2007, in connection with the acquisition of land parcels located at or adjacent to 250 West 55th Street in New York City, the Company obtained financing totaling $160.0 million. The loan was collateralized by mortgages totaling approximately $13.6 million. The mortgage loan bore interest at a variable rate equal to LIBOR plus 0.40% per annum and was scheduled to mature on January 9, 2009 with two, six-month extension options. On May 9, 2007, the Company used available cash to repay the mortgage loan.

On February 12, 2007, the Company refinanced its mortgage loan collateralized by 599 Lexington Avenue located in New York City. The new mortgage financing totaling $750.0 million bears interest at a fixed interest rate of 5.57% per annum and matures on March 1, 2017. On December 19, 2006, the Company had terminated its forward-starting interest rate swap contracts and received approximately $10.9 million, which amount will reduce the Company’s interest expense over the ten-year term of the financing, resulting in an effective interest rate of 5.38% per annum for the financing. The net proceeds of the new loan were used to refinance the $225.0 million mortgage loan on 599 Lexington Avenue and the $475.0 million mortgage loan on Times Square Tower. In connection with the refinancing, the lien of the Times Square Tower mortgage was spread to 599 Lexington Avenue and released from Times Square Tower so that Times Square Tower is no longer encumbered by any mortgage debt. The Times Square Tower mortgage loan bore interest at a variable rate equal to LIBOR plus 0.50% per annum and was scheduled to mature on July 9, 2008. There was no prepayment penalty associated with the repayment. The Company recognized a loss from early extinguishment of debt totaling approximately $0.7 million consisting of the write-off of unamortized deferred financing costs.

In connection with the acquisition of Kingstowne Towne Center in Alexandria, Virginia on March 30, 2007, the Company assumed two mortgage loans collateralized by the properties aggregating approximately $65.3 million. Pursuant to the provisions of Financial Accounting Standards Board’s (“FASB”) Statement of Financial Accounting Standards (“SFAS”) No. 141 “Business Combinations” (“SFAS No. 141”), the assumed mortgage loans of approximately $44.9 million and $20.4 million, which bear contractual interest at fixed rates of 5.99% and 5.96% and mature on January 1, 2016 and May 5, 2013, respectively, were recorded at their fair values of approximately $46.2 million and $20.8 million, respectively, using an effective interest rate of 5.50% per annum.

On May 17, 2007, the Company obtained mortgage financing totaling $25.0 million collateralized by its Montvale Center property located in Gaithersburg, Maryland. Montvale Center is a Class A office property consisting of approximately 123,000 net rentable square feet. The mortgage financing requires interest-only payments at a fixed rate equal to 5.93% per annum until maturity and matures on June 6, 2012.

6. Unsecured Exchangeable Senior Notes

On February 6, 2007, the Company completed an offering of $862.5 million in aggregate principal amount (including $112.5 million as a result of the exercise by the initial purchasers of their over-allotment option) of its 2.875% exchangeable senior notes due 2037. The notes were priced at 97.433333% of their face amount, resulting in an effective interest rate of approximately 3.438% per annum and net proceeds to the Company of approximately $840.0 million. The notes mature on February 15, 2037, unless earlier repurchased, exchanged or redeemed.

Upon the occurrence of specified events, holders of the notes may exchange their notes prior to the close of business on the scheduled trading day immediately preceding February 20, 2012 into cash and, at the Company’s option, shares of Boston Properties, Inc.’s common stock at an initial exchange rate of 6.6090 shares per $1,000 principal amount of notes (or an initial exchange price of approximately $151.31 per share of Boston Properties, Inc.’s common stock). On and after February 20, 2012, the notes will be exchangeable at any time prior to the close of business on the scheduled trading day immediately preceding the maturity date at the option of the holder at the applicable exchange rate. The initial exchange rate is subject to adjustment in certain circumstances.

Prior to February 20, 2012, the Company may not redeem the notes except to preserve Boston Properties, Inc.’s status as a REIT. On or after February 20, 2012, the Company may redeem all or a portion of the notes for cash at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest. Note holders may require the Company to repurchase all or a portion of the notes on February 15 of 2012, 2017, 2022, 2027 and 2032 at a purchase price equal to 100% of the principal amount plus accrued and unpaid interest up to, but excluding, the repurchase date. The Company will pay cash for all notes so repurchased.

If the Company undergoes a “fundamental change,” note holders will have the option to require the Company to purchase all or any portion of the notes at a purchase price equal to 100% of the principal amount of the notes to be purchased plus any accrued and unpaid interest to, but excluding, the fundamental change purchase date. The Company will pay cash for all notes so purchased. In addition, if a fundamental change occurs prior to February 20, 2012, the Company will increase the exchange rate for a holder who elects to exchange its notes in connection with such a fundamental change under certain circumstances. The notes are senior unsecured obligations of the Company and will rank equally in right of payment to all existing and future senior unsecured indebtedness and senior to any future subordinated indebtedness of the Company. The notes will effectively rank junior in right of payment to all existing and future secured indebtedness of the Company. The notes will be structurally subordinated to all liabilities of the subsidiaries of the Company.

NOTES TO THE FINANCIAL STATEMENTS—(Continued)

 

In connection with the closing, the Company and Boston Properties, Inc. entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the initial purchasers, under which the Company and Boston Properties, Inc. agreed, for the benefit of the holders of the notes, to file with the Securities and Exchange Commission and maintain a shelf registration statement providing for the sale by the holders of the notes and Boston Properties, Inc.’s common stock, if any, issuable upon exchange of the notes. The Company will be required to pay liquidated damages in the form of specified additional interest to the holders of the notes if they fail to comply with these obligations; provided that the Company will not be required to pay liquidated damages with respect to any note after it has been exchanged for any of Boston Properties, Inc.’s common stock. On March 13, 2007, the Company and Boston Properties, Inc. filed with the SEC a registration statement covering the resale of the notes and shares of common stock issuable upon exchange of the notes. The registration statement was declared effective by the SEC on April 20, 2007.

7. Unsecured Line of Credit

On August 3, 2006, the Company modified its $605.0 million unsecured revolving credit facility (the “Unsecured Line of Credit”) by extending the maturity date from October 30, 2007 to August 3, 2010, with a provision for a one-year extension at the option of the Company, subject to certain conditions, and by reducing the per annum variable interest rate on outstanding balances from Eurodollar plus 0.65% to Eurodollar plus 0.55% per annum. The Unsecured Line of Credit is a recourse obligation of the Company. Under the Unsecured Line of Credit, a facility fee equal to 15 basis points per annum is payable in quarterly installments. The interest rate and facility fee are subject to adjustment in the event of a change in the Company’s unsecured debt ratings. Effective March 22, 2007, the per annum variable interest rate was reduced to Eurodollar plus 0.475% and the facility fee was reduced to 12.5 basis points per annum as a result of an increase in the Company’s unsecured debt rating. The Unsecured Line of Credit involves a syndicate of lenders. The Unsecured Line of Credit contains a competitive bid option that allows banks that are part of the lender consortium to bid to make loan advances to the Company at a negotiated LIBOR-based rate. The Company had an outstanding balance on the Unsecured Line of Credit of $225.0 million at December 31, 2006, which was collateralized by the Company’s 599 Lexington Avenue property and therefore was included in Mortgage Notes Payable in the Company’s Consolidated Balance Sheets. On February 12, 2007, the Company repaid the $225.0 million draw that was collateralized by the Company’s 599 Lexington Avenue. As of June 30, 2007, there were no outstanding borrowings under the Unsecured Line of Credit.

The terms of the Unsecured Line of Credit require that the Company maintain a number of customary financial and other covenants on an ongoing basis, including: (1) a leverage ratio not to exceed 60%, however, the leverage ratio may increase to no greater than 65% provided that it is reduced back to 60% within 180 days, (2) a secured debt leverage ratio not to exceed 55%, (3) a fixed charge coverage ratio of at least 1.40, (4) an unsecured debt leverage ratio not to exceed 60%, however, the unsecured debt leverage ratio may increase to no greater than 65% provided that it is reduced back to 60% within 180 days, (5) a minimum net worth requirement, (6) an unsecured debt interest coverage ratio of at least 1.75 and (7) limitations on permitted investments, development, partially owned entities, business outside of commercial real estate and commercial non-office properties. At June 30, 2007, the Company was in compliance with each of these financial and other covenant requirements.

Under these provisions, the Company is not compelled to purchase the interest of its outside joint venture partners.

Insurance

The Company carries insurance coverage on its properties of types and in amounts and with deductibles that it believes are in line with coverage customarily obtained by owners of similar properties. In response to the uncertainty in the insurance market following the terrorist attacks of September 11, 2001, the Federal Terrorism Risk Insurance Act, or TRIA, was enacted in November 2002 to require regulated insurers to make available coverage for certified acts of terrorism (as defined by the statute) through December 31, 2004, which date was extended to December 31, 2005 by the United States Department of Treasury on June 18, 2004 and which date was further extended to December 31, 2007 by the Terrorism Risk Insurance Extension Act of 2005 (the “TRIA Extension Act”). TRIA expires on December 31, 2007, and the Company cannot currently anticipate whether it will be extended. Effective as of March 1, 2007, the Company’s property insurance program per occurrence limits were increased from $800 million to $900 million, including (i) coverage for “certified” acts of terrorism by TRIA of $900 million per occurrence and (ii) coverage for “non-certified” acts of terrorism by TRIA of $500 million per occurrence, and an additional $400 million of coverage for “non-certified” acts of terrorism by TRIA on a per occurrence and annual aggregate basis. The Company also carries nuclear, biological, chemical and radiological terrorism insurance coverage (“NBCR Coverage”) for “certified” acts of terrorism as defined by TRIA, which is provided by IXP, LLC as a direct insurer. Effective as of March 1, 2007, the Company extended the NBCR Coverage to March 1, 2008, excluding the Company’s Value-Added Fund properties. Effective as of March 1, 2007, the per occurrence limit for NBCR Coverage was increased from $800 million to $900 million. Under TRIA, after the payment of the required deductible and coinsurance the NBCR Coverage is backstopped by the Federal Government if the aggregate industry insured losses resulting from a certified act of terrorism exceed a “program trigger.” Under the TRIA Extension Act (a) the program trigger is $100 million from January 1, 2007 through December 31, 2007 and (b) the coinsurance is 15% from January 1, 2007 through December 31, 2007. The Company may elect to terminate the NBCR Coverage if there is a change in its portfolio or for any other reason. In the event TRIA is not extended beyond December 31, 2007 (i) the NBCR coverage provided by IXP will terminate and (ii) the Company will have some gaps in its coverage for acts of terrorism that would have constituted both “certified” and “non-certified” acts of terrorism had TRIA not expired and the Company may obtain the right to replace a portion of such coverage. The Company intends to continue to monitor the scope, nature and cost of available terrorism insurance and maintain insurance in amounts and on terms that are commercially reasonable.

The Company also currently carries earthquake insurance on its properties located in areas known to be subject to earthquakes in an amount and subject to self-insurance that the Company believes are commercially reasonable. In addition, this insurance is subject to a deductible in the amount of 5% of the value of the affected property. Specifically, the Company currently carries earthquake insurance which covers its San Francisco region with a $120 million per occurrence limit and a $120 million annual aggregate limit, $20 million of which is provided by IXP, LLC, as a direct insurer. The amount of the Company’s earthquake insurance coverage may not be sufficient to cover losses from earthquakes. The Company may discontinue earthquake insurance on some or all of its properties in the future if the premiums exceed the Company’s estimation of the value of the coverage.

In January 2002, the Company formed a wholly-owned taxable REIT subsidiary, IXP, Inc., to act as a captive insurance company and be one of the elements of the Company’s overall insurance program. On September 27, 2006, IXP, Inc. was merged into IXP, LLC, a wholly owned subsidiary, and all insurance policies issued by IXP, Inc. were cancelled and reissued by IXP, LLC. The term “IXP” refers to IXP, Inc. for the period prior to September 27, 2006 and to IXP, LLC for the period on and subsequent to September 27, 2006. IXP acts as a direct insurer with respect to a portion of the Company’s earthquake insurance coverage for its Greater San Francisco properties and the Company’s NBCR Coverage for “certified acts of terrorism” under TRIA. Insofar as the Company owns IXP, it is responsible for its liquidity and capital resources, and the accounts of IXP are part of the Company’s consolidated financial statements. In particular, if a loss occurs which is covered by the Company’s NBCR Coverage but is less than the applicable program trigger under TRIA, IXP would be responsible for the full amount of the loss without any backstop by the Federal Government. If the Company experiences a loss and IXP is required to pay under its insurance policy, the Company would ultimately record the loss to the extent of IXP’s required payment. Therefore, insurance coverage provided by IXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance.

The Company continues to monitor the state of the insurance market in general, and the scope and costs of coverage for acts of terrorism in particular, but the Company cannot anticipate what coverage will be available on commercially reasonable terms in future policy years. There are other types of losses, such as from wars or the presence of mold at the Company’s properties, for which the Company cannot obtain insurance at all or at a reasonable cost. With respect to such losses and losses from acts of terrorism, earthquakes or other catastrophic events, if the Company experiences a loss that is uninsured or that exceeds policy limits, the Company could lose the capital invested in the damaged properties, as well as the anticipated future revenues from those properties. Depending on the specific circumstances of each affected property, it is possible that the Company could be liable for mortgage indebtedness or other obligations related to the property. Any such loss could materially and adversely affect the Company’s business and financial condition and results of operations.

9. Minority Interests in Property Partnerships

The minority interests in property partnerships consist of the outside equity interests in ventures that are consolidated with the financial results of the Company because the Company exercises control over the entities that own the properties. The equity interests in these ventures that are not owned by the Company, totaled approximately $4.3 million and $12.5 million at June 30, 2007 and December 31, 2006, respectively.

On February 26, 2007, the Company entered into an agreement to redeem the outside members’ equity interest in the limited liability company that owns 250 West 55th Street for an aggregate redemption price of approximately $23.4 million. The Company paid $17.0 million on February 26, 2007, with $3.0 million payable on February 26, 2008 and the balance of approximately $3.4 million payable in monthly installments from March 1, 2007 through August 1, 2009. The redemption was accounted for using the purchase method in accordance with SFAS No. 141 “Business Combinations” (“SFAS No. 141”). The difference between the aggregate book value of the outside members’ equity interest totaling approximately $10.6 million and the purchase price increased the recorded value of the property’s net assets.

On May 31, 2007 and June 15, 2007, the Company paid an aggregate of $25.0 million in connection with the agreement entered into in May 2006 to redeem the outside members’ equity interests in the limited liability company that owns Citigroup Center. The remaining unpaid redemption price which is to be paid on May 31, 2008 is reflected at its fair value in Other Liabilities in the Company’s Consolidated Balance Sheets and totaled $23.6 million at June 30, 2007.

10. Redeemable Partnership Units

As of June 30, 2007, redeemable partnership units consisted of 20,285,414 OP Units, 676,752 LTIP Units and 1,277,463 Series Two Preferred Units (or 1,676,461 OP Units on an as converted basis) held by parties other than Boston Properties, Inc.

During the six months ended June 30, 2007, 441,767 Series Two Preferred Units of the Company were converted by the holders into 579,747 OP Units. In addition, the Company paid the accrued preferred distributions due to the holders of Preferred Units that were converted.

During the six months ended June 30, 2007, 1,112,446 OP Units (including the 579,747 OP Units issued upon conversion of the Series Two Preferred Units discussed above) were presented by the holders for redemption and were redeemed by Boston Properties, Inc. in exchange for an equal number of shares of Common Stock. The aggregate book value of the OP Units that were redeemed, as measured for each OP Unit on the date of its redemption, was approximately $23.3 million.

The Preferred Units at June 30, 2007 consist solely of 1,277,463 Series Two Preferred Units, which bear a preferred distribution equal to the greater of (1) the distribution which would have been paid in respect of the Series Two Preferred Unit had such Series Two Preferred Unit been converted into an OP Unit (including both regular and special distributions) or (2) an increasing rate, ranging from 5.00% to 7.00% per annum (7.00% for the six months ended June 30, 2007 and 2006) on a liquidation preference of $50.00 per unit, and are convertible into OP Units at a rate of $38.10 per Preferred Unit (1.312336 OP Units for each Preferred Unit). Distributions to holders of Preferred Units are recognized on a straight-line basis that approximates the effective interest method.

On January 30, 2007, the Company paid a distribution on the OP Units and LTIP Units in the amount of $0.68 per unit to holders of record as of the close of business on December 29, 2006. In addition, the Company paid a special cash distribution on the OP Units and LTIP Units in the amount of $5.40 per unit to holders of record as of the close of business on December 29, 2006. On April 30, 2007, the Company paid a distribution on the OP Units and LTIP Units in the amount of $0.68 per unit to holders of record as of the close of business on March 30, 2007.

Holders of Series Two Preferred Units participated in the $5.40 per unit special cash distribution on an as-converted basis in connection with their regular May 2007 distribution payment as provided for in the Company’s partnership agreement. At December 31, 2006, the Company had accrued approximately $12.2 million related to the $5.40 per unit special cash distribution payable to holders of the Series Two Preferred Units. During the six months ended June 30, 2007, the Company recognized an adjustment of approximately $3.1 million to the special cash distribution accrual and allocation of earnings to the Series Two Preferred Units, as a result of conversions of Series Two Preferred Units, which amount has been reflected in Preferred Distributions and Allocation of Undistributed Earnings within the Consolidated Statements of Operations.

On February 15, 2007, the Company paid a distribution on its outstanding Series Two Preferred Units of $0.89239 per unit. On May 15, 2007, the Company paid a distribution on its outstanding Series Two Preferred Units of $7.979 per unit, which amount included the impact of the special cash distribution on the OP Units and LTIP Units declared by Boston Properties, Inc., as general partner of the Company, on December 15, 2006 and paid on January 30, 2007.

On June 18, 2007, Boston Properties, Inc., as general partner of the Company, declared a distribution on the OP Units and LTIP Units in the amount of $0.68 per unit payable on July 31, 2007 to holders of record as of the close of business on June 29, 2007.

The Series Two Preferred Units may be converted into OP Units at the election of the holder thereof at any time. A holder of an OP Unit may present such OP Unit to the Company for redemption at any time (subject to restrictions agreed upon at the time of issuance of OP Units to particular holders that may restrict such redemption right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, the Company must redeem such OP Unit for cash equal to the then value of a share of common stock of Boston Properties, Inc. In lieu of a cash redemption, Boston Properties, Inc. may elect to acquire such OP Unit for one share of Common Stock. Due to the redemption option and the conversion option existing outside the control of the Company, such Preferred Units and OP Units (not owned by Boston Properties, Inc.) are not included in Partners’ Capital and are reflected in the Consolidated Balance Sheets within Redeemable Partnership Units at an amount equivalent to the value of such units had such units been redeemed at June 30, 2007. The value of the OP Units (not owned by Boston Properties, Inc. and including LTIP Units assuming that all conditions have been met for the conversion thereof) and Series Two Preferred Units had such units been redeemed at June 30, 2007 was approximately $2,140.9 million and $171.2 million, respectively, based on the closing price of Boston Properties, Inc.’s common stock of $102.13 per share on June 29, 2007. Included in Preferred Distributions and Allocation of Undistributed Earnings in the Consolidated Statements of Operations is accretion of approximately $0.1 million and $0.4 million for the three months ended June 30, 2007 and 2006, respectively, and $0.3 million and $0.8 million for the six months ended June 30, 2007 and 2006, respectively, which represents the accretion of Preferred Units from the value at issuance to the liquidation value.

11. Partners’ Capital

As of June 30, 2007, Boston Properties, Inc. owned 1,399,902 general partner units and 117,628,179 limited partner units.

During the six months ended June 30, 2007, Boston Properties, Inc. acquired 1,112,446 OP Units in connection with the redemption of an equal number of redeemable partnership units from third parties.

During the six months ended June 30, 2007, the Company issued 418,885 OP Units to Boston Properties, Inc. in connection with the exercise by employees of options to purchase Common Stock of Boston Properties, Inc.

On January 30, 2007, the Company paid a distribution in the amount of $0.68 per OP Unit to unitholders of record as of the close of business on December 29, 2006. In addition, the Company paid a special cash distribution of $5.40 per OP Unit to unitholders of record as of the close of business on December 29, 2006. On April 30, 2007, the Company paid a distribution in the amount of $0.68 per OP Unit to unitholders of record as of the close of business on March 30, 2007.

On June 18, 2007, Boston Properties, Inc., as general partner of the Company, declared a distribution in the amount of $0.68 per OP Unit payable on July 31, 2007 to unitholders of record as of the close of business on June 29, 2007.

12. Discontinued Operations

The Company applies the provisions of SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” SFAS No. 144 requires that long-lived assets that are to be disposed of by sale be measured at the lesser of (1) book value or (2) fair value less cost to sell. In addition, it requires that one accounting model be used for long-lived assets to be disposed of by sale and broadens the presentation of discontinued operations to include more disposal transactions.

During the six months ended June 30, 2007, the Company sold the following operating properties:

 

   

5 Times Square, a Class A office tower that contains approximately 1,101,779 net rentable square feet located in New York City; and

 

   

The Long Wharf Marriott, a 402-room hotel located in Boston, Massachusetts.

 

   

Newport Office Park, a Class A office property that contains approximately 172,000 net rentable square feet located in Quincy, Massachusetts.

During the year ended December 31, 2006, the Company sold 280 Park Avenue, a Class A office property totaling approximately 1,179,000 net rentable square feet located in midtown Manhattan.

Due to the Company’s continuing involvement in the management, for a fee, of 280 Park Avenue and 5 Times Square through agreements with the buyers and other financial obligations to the buyers, 280 Park Avenue and 5 Times Square have not been categorized as discontinued operations in the accompanying Consolidated Statements of Operations. As a result, the gains on sales related to 5 Times Square and 280 Park Avenue have been reflected under the caption “Gains on sales of real estate” in the Consolidated Statements of Operations. The Company has presented the other properties listed above as discontinued operations in its Consolidated Statements of Operations for the three and six months ended June 30, 2007 and 2006, as applicable.

The following table summarizes income from discontinued operations and the related realized gains on sales of real estate from discontinued operations for the three and six months ended June 30, 2007 and 2006 (in thousands):

The Company’s application of SFAS No. 144 results in the presentation of the net operating results of these qualifying properties sold or held for sale during 2007 as income from discontinued operations. The application of SFAS No. 144 does not have an impact on net income available to common unitholders. SFAS No. 144 only impacts the presentation of these properties within the Consolidated Statements of Operations.

13. Earnings Per Common Unit

Earnings per common unit has been computed pursuant to the provisions of SFAS No. 128. The following table provides a reconciliation of both the net income and the number of common units used in the computation of basic earnings per common unit, which is calculated by dividing net income available to common unitholders by the weighted-average number of common units outstanding during the period. During 2004, the Company adopted EITF 03-6 “Participating Securities and the Two-Class Method under FASB 128” (“EITF 03-6”), which provides further guidance on the definition of participating securities. Pursuant to EITF 03-6, the Company’s Series Two Preferred Units, which are reflected as Redeemable Partnership Units in the Company’s Consolidated Balance Sheets, are considered participating securities and are included in the computation of basic and diluted

earnings per common unit of the Company if the effect of applying the if-converted method is dilutive. The terms of the Series Two Preferred Units enable the holders to obtain OP Units of the Company. Accordingly, for the reporting periods in which the Company’s net income is in excess of distributions paid on the OP Units, LTIP Units and Series Two Preferred Units, such income is allocated to the OP Units, LTIP Units and Series Two Preferred Units in proportion to their respective interests and the impact is included in the Company’s consolidated basic and diluted earnings per common unit computation. For the three months ended June 30, 2007 and 2006, approximately $333,000 and $20.9 million, respectively, were allocated to the Series Two Preferred Units in excess of distributions paid during the reporting period and are included in the Company’s computation of basic and diluted earnings per common unit. For the six months ended June 30, 2007 and 2006, approximately $12.3 million and $21.7 million, respectively, were allocated to the Series Two Preferred Units in excess of distributions paid during the reporting period and are included in the Company’s computation of basic and diluted earnings per common unit. Other potentially dilutive common units, and the related impact on earnings are considered when calculating diluted earnings per common unit.

14. Stock Option and Incentive Plan

At Boston Properties, Inc.’s 2007 annual meeting of stockholders held on May 15, 2007, Boston Properties, Inc.’s stockholders approved an amendment and restatement of Boston Properties, Inc.’s 1997 Stock Option and Incentive Plan (the “Plan”) that, among other things, (1) increased the limit on full value shares (i.e., awards other than stock options) that may be issued under the Plan by 2,500,000 shares, (2) extended the term of the Plan to May 15, 2017 and (3) added provisions that allow Boston Properties, Inc. to qualify certain grants under the Plan as “performance-based compensation” under Section 162(m) of the Internal Revenue Code.

During the six months ended June 30, 2007, Boston Properties, Inc. issued 6,536 shares of restricted stock and the Company issued 156,161 LTIP Units under Boston Properties, Inc.’s stock option and incentive plan. The shares of restricted stock were valued at approximately $0.8 million ($125.46 per share weighted-average). The LTIP Units were valued at approximately $18.0 million ($115.47 per unit weighted-average fair value) using an option pricing model in accordance with the provisions of SFAS No. 123R. The per unit fair value of each LTIP Unit granted was estimated on the date of grant using the following assumptions: an expected life of 5.3 years, a risk-free interest rate of 4.82% and an expected price volatility of 18.0%. An LTIP Unit is generally the economic equivalent of a share of restricted stock in Boston Properties, Inc. The aggregate value of the LTIP Units is included in Redeemable Partnership Units in the Consolidated Balance Sheets. The restricted stock and

NOTES TO THE FINANCIAL STATEMENTS—(Continued)

 

LTIP Units granted to employees between January 1, 2004 and November 2006 vest over a five-year term. Grants of restricted stock and LTIP Units made in and after November 2006 vest in four equal annual installments. Restricted stock and LTIP Units are measured at fair value on the date of grant based on the number of shares or units granted, as adjusted for forfeitures and the price of Boston Properties, Inc.’s Common Stock on the date of grant as quoted on the New York Stock Exchange. Such value is recognized as an expense ratably over the corresponding employee service period. Dividends paid on both vested and unvested shares of restricted stock are charged directly to Partners’ Capital and Redeemable Partnership Units in the Consolidated Balance Sheets. Stock-based compensation expense associated with restricted stock and LTIP Units was approximately $2.8 million and $1.8 million for the three months ended June 30, 2007 and 2006, respectively, and $5.8 million and $4.1 million for the six months ended June 30, 2007 and 2006, respectively. At June 30, 2007, there was $31.2 million of unrecognized compensation cost related to unvested restricted stock and LTIP Units that is expected to be recognized over a weighted-average period of approximately 3.1 years.

15. Segment Information

The Company’s segments are based on the Company’s method of internal reporting which classifies its operations by both geographic area and property type. The Company’s segments by geographic area are Greater Boston, Greater Washington, D.C., Midtown Manhattan, Greater San Francisco and New Jersey. Segments by property type include: Class A Office, Office/Technical and Hotel.

Asset information by segment is not reported because the Company does not use this measure to assess performance. Therefore, depreciation and amortization expense is not allocated among segments. Interest and other income, development and management services, general and administrative expenses, interest expense, depreciation and amortization expense, minority interest in property partnership, income from unconsolidated joint ventures, gains on sales of real estate, income from discontinued operations, gains on sales of real estate from discontinued operations and losses from early extinguishments of debt are not included in Net Operating Income as the internal reporting addresses these items on a corporate level.

Net Operating Income is not a measure of operating results or cash flows from operating activities as measured by accounting principles generally accepted in the United States of America, and it is not indicative of cash available to fund cash needs and should not be considered an alternative to cash flows as a measure of liquidity. All companies may not calculate Net Operating Income in the same manner. The Company considers Net Operating Income to be an appropriate supplemental measure to net income because it helps both investors and management to understand the core operations of the Company’s properties.

16. Newly Issued Accounting Standards

In June 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109” (“FIN No. 48”). FIN No. 48 clarifies the accounting for uncertainty in income taxes recognized in a company’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN No. 48 also provides guidance on description, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN No. 48 was effective for fiscal years beginning after December 15, 2006. FIN No. 48, which was adopted by the Company effective January 1, 2007, did not have a material impact on the Company’s cash flows, results of operations, financial position or liquidity.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS No. 157”). SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles (GAAP), and expands disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements. SFAS No. 157 applies under other accounting pronouncements that require or permit fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. The Company does not expect the adoption of SFAS No. 157 to have a material impact on the Company’s cash flows, results of operations, financial position or liquidity.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115” (“SFAS No. 159”). SFAS No. 159 permits entities to choose, at specified election dates, to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. Unrealized gains and losses shall be reported on items for which the fair value option has been elected in earnings at each subsequent reporting date. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating and assessing the impact of this statement.

17. Subsequent Events

On July 16, 2007, the Company entered into a joint venture with an unrelated third party to develop a Class A office complex aggregating approximately 425,000 net rentable square feet located in Anne Arundel County, Maryland. The joint venture partner contributed the land for a 50% interest. The Company will contribute cash of approximately $14.9 million for its 50% interest in the joint venture. The joint venture has commenced construction on an approximately 114,000 net rentable square foot Class A office property on the site.

On July 25, 2007, the Company, together with Boston Properties, Inc., filed a combined so-called “universal shelf” registration statement with the Securities and Exchange Commission to update and replace a series of existing registration statements covering the possible issuance by either the Company or Boston Properties, Inc. of various equity and debt securities. This registration statement was declared effective by the SEC on August 6, 2007 and will give the Company and/or Boston Properties, Inc. flexibility to offer and sell from time to time, in one or more offerings, up to $2.0 billion of senior and subordinated debt securities (including Company notes exchangeable for Boston Properties, Inc. common stock and Boston Properties, Inc. convertible notes), as well as Boston Properties, Inc. common stock, preferred stock and warrants.

On July 27, 2007 and August 3, 2007, the Company entered into four treasury lock contracts with a weighted-average fixed rate of 4.782% on notional amounts aggregating $200.0 million. The contracts expire on April 1, 2008.

On August 6, 2007, the Company used available cash to repay the mortgage loan collateralized by its Embarcadero Center Four property located in San Francisco, California totaling approximately $131.2 million. There was no prepayment penalty associated with the repayment. The mortgage loan bore interest at a fixed rate of 6.79% per annum and was scheduled to mature on February 1, 2008.

On August 7, 2007, the Company sold Democracy Center in Bethesda, Maryland, for approximately $280.5 million. Democracy Center is a Class A office complex that contains an aggregate of approximately 685,000 net rentable square feet. The sale price for the property exceeded its carrying value. In conjunction with the sale, the Company repaid the mortgage financing collateralized by the property totaling approximately $94.6 million. The Company paid a prepayment fee of approximately $2.6 million associated with the repayment. The mortgage loan bore interest at a fixed rate of 7.05% per annum and was scheduled to mature on April 1, 2009.

ITEM 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations

As used herein, the terms “BPLP,” “we,” “us” and “our” refer to Boston Properties Limited Partnership, a Delaware limited partnership, and its subsidiaries, and its respective predecessor entities, considered a single enterprise.

The following discussion should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report. This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the federal securities laws. We caution investors that any forward-looking statements presented in this report, or which management may make orally or in writing from time to time, are based on beliefs and assumptions made by, and information currently available to, management. When used, the words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “project,” “result,” “should,” “will” and similar expressions which do not relate solely to historical matters are intended to identify forward-looking statements. Such statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance, which may be affected by known and unknown risks, trends, uncertainties and factors that are beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected by the forward-looking statements. We caution you that while forward-looking statements reflect our good-faith beliefs when we make them, they are not guarantees of future performance and are impacted by actual events when they occur after we make such statements. Accordingly, investors should use caution in relying on forward-looking statements, which are based on results and trends at the time they are made, to anticipate future results or trends.

Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include, among others, the following:

 

   

general risks affecting the real estate industry (including, without limitation, the inability to enter into or renew leases, dependence on tenants’ financial condition, and competition from other developers, owners and operators of real estate);

 

   

failure to manage effectively our growth and expansion into new markets and sub-markets or to integrate acquisitions and developments successfully;

 

   

risks and uncertainties affecting property development and construction (including, without limitation, construction delays, cost overruns, inability to obtain necessary permits and public opposition to such activities);

 

   

risks associated with the availability and terms of financing and the use of debt to fund acquisitions and developments, including the risk associated with interest rates impacting the cost and/or availability of financing;

 

   

risks associated with forward interest rate contracts and the effectiveness of such arrangements;

 

   

risks associated with downturns in the national and local economies, increases in interest rates, and volatility in the securities markets;

 

   

risks associated with actual or threatened terrorist attacks;

 

   

risks associated with the impact on our insurance program if TRIA, which expires on December 31, 2007, is not extended or is extended on different terms;

 

   

costs of compliance with the Americans with Disabilities Act and other similar laws;

 

   

potential liability for uninsured losses and environmental contamination;

 

   

risks associated with Boston Properties, Inc.’s potential failure to qualify as a REIT under the Internal Revenue Code of 1986, as amended;

 

   

possible adverse changes in tax and environmental laws;

 

26


Table of Contents
   

risks associated with possible state and local tax audits;

 

   

risks associated with our dependence on key personnel whose continued service is not guaranteed; and

 

   

the other risk factors identified in our most recently filed Annual Report on Form 10-K, including those described under the caption “Risk Factors.”

The risks set forth above are not exhaustive. Other sections of this report may include additional factors that could adversely affect our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all risk factors, nor can it assess the impact of all risk factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results. Investors should also refer to our most recent Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q for future periods and Current Reports on Form 8-K as we file them with the SEC, and to other materials we may furnish to the public from time to time through Forms 8-K or otherwise, for a discussion of risks and uncertainties that may cause actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements. We expressly disclaim any responsibility to update any forward-looking statements to reflect changes in underlying assumptions or factors, new information, future events, or otherwise, and you should not rely upon these forward-looking statements after the date of this report.

Overview

Boston Properties Limited Partnership is the entity through which Boston Properties, Inc., a fully integrated self-administered and self-managed real estate investment trust, or “REIT,” and one of the largest owners and developers of Class A office properties in the United States, conducts substantially all of its business and owns (either directly or through subsidiaries) substantially all of its assets. Our properties are concentrated in five markets—Boston, midtown Manhattan, Washington, D.C., San Francisco and Princeton, NJ. We generate revenue and cash primarily by leasing our Class A office space to our tenants. Factors we consider when we lease space include the creditworthiness of the tenant, the length of the lease, the rental rate to be paid, the costs of tenant improvements, current and anticipated operating costs and real estate taxes, our current and anticipated vacancy, current and anticipated future demand for office space generally and general economic factors. We also generate cash through the sale of assets, which may be either non-core assets or core assets that command premiums from real estate investors.

Our core strategy has always been to operate in supply constrained markets, so given the combination of strong demand, increasing replacement costs and scarcity of supply, we expect our assets to continue to appreciate over time. Over the past few years there has been a significant change in the ownership of high-quality real estate as foreign buyers, private equity funds and private individuals have purchased public companies, portfolios and major assets. We continue to experience strong rent growth and a reduction of high-quality space alternatives in Boston, New York, Washington, D.C. and San Francisco, and we expect that the aggressive pricing efforts of these new owners will help to continue this favorable trend for sometime. The impact on our rental revenues will be felt gradually, however, given the modest amount of our 2007 lease expirations.

Given current market conditions, we generally believe that the returns we can generate from development will be significantly greater than those we can expect to realize from acquisitions. As a result, our strategy remains unchanged as we continue operating in 2007; we intend to selectively sell assets, reduce the overall size of the in-service portfolio and replace the sold assets with substantial investments in new development opportunities. In August 2007, we sold Democracy Center, a Class A office property in Bethesda, Maryland, for approximately $280.5 million. With the addition of this sale, we have completed over $4.1 billion of asset sales over the past two years. Excluding 5 Times Square, we have already sold or have under contract for sale in 2007, an additional $582 million of assets compared to our stated expectation for a minimum of $500 million of asset

sales during the year. During 2006, we started more than $300 million of developments and, in 2007, we anticipate starting approximately $1.7 billion of developments, including commencing construction on our approximately 1.0 million square foot office tower in New York City on West 55th Street. While the asset sales will have the impact of dampening our short-term, year-to-year earnings growth rate, we believe our intensive focus on new development will enhance our long-term return on equity and earnings growth as these developments are placed in-service in 2009, 2010 and 2011.

The highlights of the three months ended June 30, 2007 included the following:

 

   

On April 5, 2007, we sold our Newport Office Park located in Quincy, Massachusetts, for approximately $37.0 million. Newport Office Park is a Class A office property consisting of approximately 172,000 net rentable square feet. Net cash proceeds totaled approximately $33.7 million.

 

   

On April 11, 2007, we acquired a parcel of land located in Springfield, Virginia, for a purchase price of approximately $25.6 million.

 

   

On April 12, 2007, we entered into an agreement for the sale of a parcel of land located in Washington, D.C. for approximately $33.7 million. In addition, we entered into a development management agreement with the buyer to develop on the parcel a Class A office property totaling approximately 165,000 net rentable square feet. The sale is subject to the satisfaction of customary closing conditions and there can be no assurance that the sale will be consummated on the terms currently contemplated or at all.

 

   

On May 9, 2007, we used available cash to repay the mortgage loan collateralized by our 250 West 55th Street project located in New York City totaling approximately $160.0 million. There was no prepayment penalty associated with the repayment. The mortgage loan bore interest at a variable rate equal to LIBOR plus 0.40% per annum and was scheduled to mature in January 2009.

 

   

On May 17, 2007, we obtained mortgage financing totaling $25.0 million collateralized by our Montvale Center property located in Gaithersburg, Maryland. Montvale Center is a Class A office property consisting of approximately 123,000 net rentable square feet. The mortgage financing bears interest at a fixed rate equal to 5.93% per annum and matures on June 6, 2012.

 

   

On June 1, 2007, our Value-Added Fund sold Worldgate Plaza located in Herndon, Virginia for approximately $109.0 million. Worldgate Plaza is an office complex consisting of approximately 322,000 net rentable square feet. Net cash proceeds totaled approximately $50.5 million, of which our share was approximately $20.3 million, after the repayment of the mortgage indebtedness of $57.0 million. The mortgage loan bore interest at a variable rate equal to LIBOR plus 0.89% per annum and was scheduled to mature on December 1, 2007.

 

   

On June 11, 2007, we entered into a lease agreement with The Trustees of Princeton University for a build-to-suit project with approximately 120,000 net rentable square feet of Class A office space which we have the rights to acquire on land located in Princeton, New Jersey. We expect that the building will be complete and available for occupancy during the fourth quarter of 2009.

 

   

On June 22, 2007, a joint venture in which we have a 50% interest entered into agreements to complete the assemblage for its development site at Eighth Avenue and 46th Street in New York City consisting of an approximately 840,000 net rentable square foot Class A office property.

Transactions completed subsequent to June 30, 2007:

 

   

On July 16, 2007, we entered into a joint venture with an unrelated third party to develop a Class A office complex aggregating approximately 425,000 net rentable square feet located in Anne Arundel County, Maryland. The joint venture partner contributed the land for a 50% interest. We will contribute cash of approximately $14.9 million for our 50% interest in the joint venture. The joint venture has commenced construction on an approximately 114,000 net rentable square foot Class A office property on the site.

On July 25, 2007, we, together with Boston Properties, Inc., filed a combined so-called “universal shelf” registration statement with the Securities and Exchange Commission to update and replace a series of existing registration statements covering the possible issuance by us or Boston Properties, Inc. of various equity and debt securities. This registration statement was declared effective by the SEC on August 6, 2007 and will give us and/or Boston Properties, Inc. flexibility to offer and sell from time to time, in one or more offerings, up to $2.0 billion of senior and subordinated debt securities (including our notes exchangeable for our common stock and convertible notes), as well as Boston Properties, Inc.’s common stock, preferred stock and warrants.

On July 27, 2007 and August 3, 2007, we entered into four treasury lock contracts with a weighted-average fixed rate of 4.782% on notional amounts aggregating $200.0 million. The contracts expire on April 1, 2008.

On August 6, 2007, we used available cash to repay the mortgage loan collateralized by our Embarcadero Center Four property located in San Francisco, California totaling approximately $131.2 million. There was no prepayment penalty associated with the repayment. The mortgage loan bore interest at a fixed rate of 6.79% per annum and was scheduled to mature on February 1, 2008.

On August 7, 2007, we sold Democracy Center in Bethesda, Maryland, for approximately $280.5 million. Democracy Center is a Class A office complex that contains an aggregate of approximately 685,000 net rentable square feet. The sale price for the property exceeded its carrying value. In conjunction with the sale, we repaid the mortgage financing collateralized by the property totaling approximately $94.6 million. We paid a prepayment fee of approximately $2.6 million associated with the repayment. The mortgage loan bore interest at a fixed rate equal to 7.05% per annum and was scheduled to mature on April 1, 2009.

Update on Recent Regulatory Initiatives

On July 25, 2007, the FASB authorized a FASB Staff Position (the “proposed FSP”) that would require the liability and equity components of convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement) to be separately accounted for in a manner that reflects the issuer’s nonconvertible debt borrowing rate. If issued as currently contemplated, the proposed FSP would require that the initial debt proceeds from the sale of our $862.5 million of 2.875% exchangeable senior notes due 2037 and $450.0 million of 3.75% exchangeable senior notes due 2036 be allocated between a liability component and an equity component in a manner that reflects interest expense at the interest rate of similar nonconvertible debt. To allocate the proceeds in this manner, the issuer would first need to determine the carrying amount of the liability component, which would be based on the fair value of a similar liability (excluding the embedded conversion option). The resulting debt discount would be amortized over the period during which the debt is expected to be outstanding as additional non-cash interest expense. The proposed FSP would be effective for financial statements issued for fiscal years beginning after December 15, 2007 and interim periods within those fiscal years. The proposed FSP would be applied retrospectively to our outstanding exchangeable senior notes for all periods presented. Based on our current understanding of the application of the proposed FSP, this would result in an aggregate of approximately $18 million of additional non-cash interest expense for fiscal 2007. The additional expense will increase in subsequent reporting periods through the first optional redemption date as the debt accretes to its par value over the same period. There can be no assurance that the proposed FSP will be issued in the form currently contemplated by the FASB, or at all, and therefore its ultimate impact on our interest expense may differ materially from the aforementioned estimates.

Legislation was recently introduced in Congress that would treat publicly traded partnerships as corporations for federal income tax purposes if the partnership directly or indirectly derives income from certain investment adviser or asset management services. Because certain of our current activities could constitute investment adviser or asset management services as defined for these purposes, unless transfers of ownership of interests are limited in a manner that complies with certain regulatory safe harbors or another exception applies, it is possible that this legislation, if enacted, could cause us to be taxable as a corporation. Classification as a

corporation would also cause Boston Properties, Inc. to fail to qualify as a REIT. Under a transitional rule contained in one version of the proposed legislation, we would be exempt from the new rules until its taxable year beginning January 1, 2013. An alternative proposal, however, would shorten the transition period to make the new law applicable to existing publicly-traded partnerships beginning January 1, 2008, and it is possible that any legislation ultimately enacted could be effective immediately or possibly even retroactively.

Congress is also considering legislative proposals to treat all or part of certain income allocated to a partner by a partnership in respect of certain services provided to or for the benefit of the partnership (“carried interest revenue”) as ordinary income for U.S. federal income tax purposes. While the current legislative proposal provides that such income will nevertheless retain its original character for purposes of the REIT qualification tests, it is not clear what form any such final legislation would take. Furthermore, under the proposed legislation, carried interest revenue could be treated as non-qualifying income for purposes of the “qualifying income” exception to the publicly-traded partnership rules. If enacted, this could result in us being taxable as a corporation for U.S. federal income tax purposes if the amount of any such carried interest revenue plus any other non-qualifying income earned exceeds 10% of its gross income in any taxable year.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to use judgment in the application of accounting policies, including making estimates and assumptions. We base our estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. These judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. If our judgment or interpretation of the facts and circumstances relating to various transactions had been different, it is possible that different accounting policies would have been applied resulting in a different presentation of our financial statements. From time to time, we evaluate our estimates and assumptions. In the event estimates or assumptions prove to be different from actual results, adjustments are made in subsequent periods to reflect more current information. Below is a discussion of accounting policies that we consider critical in that they may require complex judgment in their application or require estimates about matters that are inherently uncertain.

Real Estate

Upon acquisitions of real estate, we assess the fair value of acquired tangible and intangible assets, including land, buildings, tenant improvements, “above-” and “below-market” leases, origination costs, acquired in-place leases, other identified intangible assets and assumed liabilities in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 141, “Business Combinations” and allocate the purchase price to the acquired assets and assumed liabilities, including land at appraised value and buildings at replacement cost. We assess and consider fair value based on estimated cash flow projections that utilize discount and/or capitalization rates that we deem appropriate, as well as available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known and anticipated trends, and market and economic conditions. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. We also consider an allocation of purchase price of other acquired intangibles, including acquired in-place leases that may have a customer relationship intangible value, including (but not limited to) the nature and extent of the existing relationship with the tenants, the tenants’ credit quality and expectations of lease renewals. Based on our acquisitions to date, our allocation to customer relationship intangible assets has been immaterial.

We record acquired “above-” and “below-market” leases at their fair values (using a discount rate which reflects the risks associated with the leases acquired) equal to the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) management’s estimate of fair market lease rates for each corresponding in-place lease, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the term of any below-market fixed rate renewal options for below-market leases.

Other intangible assets acquired include amounts for in-place lease values that are based on our evaluation of the specific characteristics of each tenant’s lease. Factors to be considered include estimates of carrying costs during hypothetical expected lease-up periods considering current market conditions, and costs to execute similar leases. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, we consider leasing commissions, legal and other related expenses.

Real estate is stated at depreciated cost. The cost of buildings and improvements includes the purchase price of property, legal fees and other acquisition costs. Costs directly related to the development of properties are capitalized. Capitalized development costs include interest, internal wages, property taxes, insurance, and other project costs incurred during the period of development.

Management reviews its long-lived assets used in operations for impairment when there is an event or change in circumstances that indicates an impairment in value. An impairment loss is recognized if the carrying amount of its assets is not recoverable and exceeds its fair value. If such impairment is present, an impairment loss is recognized based on the excess of the carrying amount of the asset over its fair value. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. Since cash flows on properties considered to be “long-lived assets to be held and used” as defined by SFAS No. 144 “Accounting for the Impairment or Disposal of Long-Lived Assets,” (“SFAS No. 144”) are considered on an undiscounted basis to determine whether an asset has been impaired, our established strategy of holding properties over the long term directly decreases the likelihood of recording an impairment loss. If our strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized and such loss could be material. If we determine that impairment has occurred, the affected assets must be reduced to their fair value. No such impairment losses have been recognized to date.

SFAS No. 144 requires that qualifying assets and liabilities and the results of operations that have been sold, or otherwise qualify as “held for sale,” be presented as discontinued operations in all periods presented if the property operations are expected to be eliminated and we will not have significant continuing involvement following the sale. The components of the property’s net income that is reflected as discontinued operations include the net gain (or loss) upon the disposition of the property held for sale, operating results, depreciation and interest expense (if the property is subject to a secured loan). We generally consider assets to be “held for sale” when the transaction has been approved by the Board of Directors of Boston Properties, Inc., or a committee thereof, and there are no known significant contingencies relating to the sale, such that the property sale within one year is considered probable. Following the classification of a property as “held for sale,” no further depreciation is recorded on the assets.

A variety of costs are incurred in the acquisition, development and leasing of properties. After the determination is made to capitalize a cost, it is allocated to the specific component of a project that is benefited. Determination of when a development project commences and capitalization begins and when a development project is substantially complete and capitalization must cease involves a degree of judgment. Our capitalization policy on development properties is guided by SFAS No. 34 “Capitalization of Interest Cost” and SFAS No. 67 “Accounting for Costs and the Initial Rental Operations of Real Estate Projects.” The costs of land and buildings under development include specifically identifiable costs. The capitalized costs include pre-construction costs necessary to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. We begin the capitalization of costs during the pre-construction period which we define as activities that are necessary to the development of the property. We consider a construction project as substantially completed and held available for occupancy upon the completion of tenant improvements, but no later than one year from cessation of major construction activity. We cease capitalization on the portion (1) substantially completed and (2) occupied or held available for occupancy, and we capitalize only those costs associated with the portion under construction.

Investments in Unconsolidated Joint Ventures

Except for ownership interests in variable interest entities, we account for our investments in joint ventures under the equity method of accounting because we exercise significant influence over, but do not control, these entities. These investments are recorded initially at cost, as Investments in Unconsolidated Joint Ventures, and subsequently adjusted for equity in earnings and cash contributions and distributions. Any difference between the carrying amount of these investments on our balance sheet and the underlying equity in net assets is amortized as an adjustment to equity in earnings of unconsolidated joint ventures over the life of the related asset. Under the equity method of accounting, our net equity is reflected within the Consolidated Balance Sheets, and our share of net income or loss from the joint ventures is included within the Consolidated Statements of Operations. The joint venture agreements may designate different percentage allocations among investors for profits and losses, however, our recognition of joint venture income or loss generally follows the joint venture’s distribution priorities, which may change upon the achievement of certain investment return thresholds. For ownership interests in variable interest entities, we consolidate those in which we are the primary beneficiary.

Revenue Recognition

Base rental revenue is reported on a straight-line basis over the terms of our respective leases. In accordance with SFAS No. 141, we recognize rental revenue of acquired in-place “above-” and “below-market” leases at their fair values over the terms of the respective leases. Accrued rental income as reported on the Consolidated Balance Sheets represents rental income recognized in excess of rent payments actually received pursuant to the terms of the individual lease agreements.

Our leasing strategy is generally to secure creditworthy tenants that meet our underwriting guidelines. Furthermore, following the initiation of a lease, we continue to actively monitor the tenant’s creditworthiness to ensure that all tenant related assets are recorded at their realizable value. When assessing tenant credit quality, we:

 

   

review relevant financial information, including:

 

   

financial ratios;

 

   

net worth;

 

   

debt to market capitalization; and

 

   

liquidity;

 

   

evaluate the depth and experience of the tenant’s management team; and

 

   

assess the strength/growth of the tenant’s industry.

As a result of the underwriting process, tenants are then categorized into one of three categories:

 

  (1) low risk tenants;

 

  (2) the tenant’s credit is such that we require collateral, in which case we:

 

   

require a security deposit; and/or

 

   

reduce upfront tenant improvement investments; or

 

  (3) the tenant’s credit is below our acceptable parameters.

We maintain a rigorous process of monitoring the credit quality of our tenant base. We provide an allowance for doubtful accounts arising from estimated losses that could result from the tenant’s inability to make required current rent payments and an allowance against accrued rental income for future potential losses that we deem to be unrecoverable over the term of the lease.

Tenant receivables are assigned a credit rating of 1-4 with a rating of 1 representing the highest possible rating with no allowance recorded and a rating of 4 representing the lowest credit rating, recording a full reserve against the receivable balance. Among the factors considered in determining the credit rating include:

 

   

payment history;

 

   

credit status and change in status (credit ratings for public companies are used as a primary metric);

 

32


Table of Contents
   

change in tenant space needs (i.e., expansion/downsize);

 

   

tenant financial performance;

 

   

economic conditions in a specific geographic region; and

 

   

industry specific credit considerations.

If our estimates of collectibility differ from the cash received, the timing and amount of our reported revenue could be impacted. The average remaining term of our in-place tenant leases was approximately 7.3 years as of June 30, 2007. The credit risk is mitigated by the high quality of our existing tenant base, reviews of prospective tenants’ risk profiles prior to lease execution and frequent monitoring of our portfolio to identify potential problem tenants.

Recoveries from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs, are recognized as revenue in the period the expenses are incurred. Tenant reimbursements are recognized and presented in accordance with Emerging Issues Task Force, or EITF, Issue 99-19 “Reporting Revenue Gross as a Principal versus Net as an Agent,” or Issue 99-19. Issue 99-19 requires that these reimbursements be recorded on a gross basis, as we are generally the primary obligor with respect to purchasing goods and services from third-party suppliers, have discretion in selecting the supplier and have credit risk. We also receive reimbursement of payroll and payroll related costs from third parties which we reflect on a net basis in accordance with Issue 99-19.

Our hotel revenues are derived from room rentals and other sources such as charges to guests for long-distance telephone service, fax machine use, movie and vending commissions, meeting and banquet room revenue and laundry services. Hotel revenues are recognized as earned.

We receive management and development fees from third parties. Management fees are recorded and earned based on a percentage of collected rents at the properties under management, and not on a straight-line basis, because such fees are contingent upon the collection of rents. We review each development agreement and record development fees on a straight-line basis or percentage of completion depending on the risk associated with each project. Profit on development fees earned from joint venture projects is recognized as revenue to the extent of the third party partners’ ownership interest.

Gains on sales of real estate are recognized pursuant to the provisions of SFAS No. 66, “Accounting for Sales of Real Estate.” The specific timing of the sale is measured against various criteria in SFAS No. 66 related to the terms of the transactions and any continuing involvement in the form of management or financial assistance associated with the properties. If the sales criteria are not met, we defer gain recognition and account for the continued operations of the property by applying the finance, installment or cost recovery methods, as appropriate, until the sales criteria are met.

Depreciation and Amortization

We compute depreciation and amortization on our properties using the straight-line method based on estimated useful asset lives. In accordance with SFAS No. 141, we allocate the acquisition cost of real estate to land, building, tenant improvements, acquired “above-” and “below-market” leases, origination costs and acquired in-place leases based on an assessment of their fair value and depreciate or amortize these assets over their useful lives. The amortization of acquired “above-” and “below-market” leases and acquired in-place leases is recorded as an adjustment to revenue and depreciation and amortization, respectively, in the Consolidated Statements of Operations.

Fair Value of Financial Instruments

For purposes of disclosure, we calculate the fair value of our mortgage notes payable and unsecured senior notes. We discount the spread between the future contractual interest payments and future interest payments on our mortgage debt and unsecured notes based on a current market rate. In determining the current market rate, we

 

33


Table of Contents

add our estimate of a market spread to the quoted yields on federal government treasury securities with similar maturity dates to our own debt. Because our valuations of our financial instruments are based on these types of estimates, the fair value of our financial instruments may change if our estimates do not prove to be accurate.

Results of Operations

The following discussion is based on our Consolidated Financial Statements for the three and six months ended June 30, 2007 and 2006.

At June 30, 2007 and June 30, 2006, we owned or had interests in a portfolio of 134 and 124 properties, respectively (in each case, the “Total Property Portfolio”). As a result of changes within our Total Property Portfolio, the financial data presented below shows significant changes in revenue and expenses from period-to-period. Accordingly, we do not believe that our period-to-period financial data with respect to the Total Property Portfolio are necessarily meaningful. Therefore, the comparison of operating results for the three and six months ended June 30, 2007 and 2006 show separately the changes attributable to the properties that were owned by us throughout each period compared (the “Same Property Portfolio”) and the changes attributable to the Total Property Portfolio.

In our analysis of operating results, particularly to make comparisons of net operating income between periods meaningful, it is important to provide information for properties that were in-service and owned by us throughout each period presented. We refer to properties acquired or placed in-service prior to the beginning of the earliest period presented and owned by us through the end of the latest period presented as our Same Property Portfolio. The Same Property Portfolio therefore excludes properties placed in-service, acquired or repositioned after the beginning of the earliest period presented or disposed of prior to the end of the latest period presented.

Net operating income, or “NOI,” is a non-GAAP financial measure equal to net income available to common unitholders, the most directly comparable GAAP financial measure, plus preferred distributions and allocation of undistributed earnings, losses from early extinguishment of debt, depreciation and amortization, interest expense, general and administrative expense, income from discontinued operations, less gains on sales of real estate, gains on sales of real estate from discontinued operations, income from unconsolidated joint ventures, minority interest in property partnership, interest and other income and development and management services revenue. We use NOI internally as a performance measure and believe NOI provides useful information to investors regarding our financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level. Therefore, we believe NOI is a useful measure for evaluating the operating performance of our real estate assets.

Our management also uses NOI to evaluate regional property level performance and to make decisions about resource allocations. Further, we believe NOI is useful to investors as a performance measure because, when compared across periods, NOI reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspective not immediately apparent from net income. NOI excludes certain components from net income in order to provide results that are more closely related to a property’s results of operations. For example, interest expense is not necessarily linked to the operating performance of a real estate asset and is often incurred at the corporate level as opposed to the property level. In addition, depreciation and amortization, because of historical cost accounting and useful life estimates, may distort operating performance at the property level. NOI presented by us may not be comparable to NOI reported by other REITs that define NOI differently. We believe that in order to facilitate a clear understanding of our operating results, NOI should be examined in conjunction with net income as presented in our consolidated financial statements. NOI should not be considered as an alternative to net income as an indication of our performance or to cash flows as a measure of liquidity or ability to make distributions.

Comparison of the six months ended June 30, 2007 to the six months ended June 30, 2006.

The table below shows selected operating information for the Same Property Portfolio and the Total Property Portfolio. The Same Property Portfolio consists of 111 properties totaling approximately 27.8 million net rentable square feet of space. The Same Property Portfolio includes properties acquired or placed in-service on or prior to January 1, 2006 and owned through June 30, 2007. In addition, the Same Property Portfolio includes our Cambridge Center Marriott hotel property, but does not include the Long Wharf Marriott hotel property, which was sold on March 23, 2007. The Total Property Portfolio includes the effects of the other properties either placed in-service, acquired or repositioned after January 1, 2006 or disposed of on or prior to June 30, 2007. This table includes a reconciliation from the Same Property Portfolio to the Total Property Portfolio by also providing information for the six months ended June 30, 2007 and 2006 with respect to the properties which were acquired, placed in-service, repositioned or sold.

During July 2006, we placed in-service our Capital Gallery expansion project, consisting of a ten-story addition totaling approximately 319,000 net rentable square feet of Class A office space located in Washington, D.C. The project entailed removing a three-story, low-rise section of the property from in-service status and developing it into a ten-story office building resulting in a total complex size of approximately 615,000 net rentable square feet. In April 2006, tenants began to take initial occupancy. This property is included in Properties Repositioned for the six months ended June 30, 2007 and June 30, 2006.

Rental Revenue

The decrease of approximately $3.4 million in the Total Property Portfolio is comprised of increases and decreases within the five categories that comprise our Total Property Portfolio. Rental revenue from the Same Property Portfolio increased approximately $26.2 million, Properties Sold decreased approximately $59.6 million, Properties Acquired increased approximately $21.2 million, Properties Placed In-Service increased approximately $3.9 million and Properties Repositioned increased approximately $4.9 million.

We incur certain tenant specific property costs for which we are reimbursed from our tenants. Starting in 2007, we have included these reimbursements in rental revenue and included the tenant specific operating cost within real estate operating expenses. This income and expense classification in 2007 results in a presented increase to comparable rental revenue and real estate operating expenses, however does not impact our consolidated net operating income. For the six months ended June 30, 2007 and 2006, the rental income and real estate operating expense gross up was approximately $4.5 million and $5.1 million, respectively.

Rental revenue from the Same Property Portfolio increased approximately $26.2 million for the six months ended June 30, 2007 compared to 2006. Included in rental revenue is an overall increase in base rental revenue of approximately $15.0 million. Approximately $9.2 million of the increase from the Same Property Portfolio was due to an increase in recoveries from tenants which correlates with the increase in operating expenses. We collected almost $2.0 million in connection with a modification to the calculation of a tenant’s real estate tax operating expense obligation from a lease that commenced in 1999 and was adjusted for the last six years. The remaining $1.6 million increase related to parking and other income. We expect occupancy to remain level and same property net operating income to grow approximately 3% over our same property net operating income in 2006. In addition, we expect straight-line rents and FAS 141 adjustments for the remainder of 2007 to contribute between $8 million and $10 million to rental revenue per quarter.

The acquisitions of 6601 & 6605 Springfield Center Drive, 103 Fourth Avenue and Kingstowne Towne Center during the six months ended June 30, 2007 as well as the acquisitions during 2006 increased rental revenue from Properties Acquired by approximately $21.2 million for the six months ended June 30, 2007 as detailed below:

Our Capital Gallery expansion project is included in Properties Repositioned for the six months ended June 30, 2007 and June 30, 2006. In April 2006, tenants began to take occupancy and we placed our Capital Gallery expansion project in-service in July 2006.

The aggregate increase in rental revenue was offset by the sales of 5 Times Square in February 2007 and 280 Park Avenue in June 2006. These properties have not been classified as discontinued operations due to our continuing involvement as the property manager for each property. Rental Revenue from Properties Sold decreased by approximately $59.6 million, as detailed below:

Termination Income

Termination income for the six months ended June 30, 2007 was related to ten tenants across the Total Property Portfolio that terminated their leases, and we recognized termination income totaling approximately $3.3 million. This compared to termination income of approximately $2.2 million for the six months ended June 30, 2006 related to ten tenants. We currently anticipate realizing approximately $1.0 million in termination income per quarter for the remainder of 2007.

Real Estate Operating Expenses

The $5.4 million increase in property operating expenses (real estate taxes, utilities, insurance, repairs and maintenance, cleaning and other property-related expenses) in the Total Property Portfolio is comprised of increases and decreases within five categories that comprise our Total Property Portfolio. Operating expenses for the Same Property Portfolio increased approximately $15.3 million, Properties Sold decreased approximately $19.7 million, Properties Acquired increased approximately $6.6 million, Properties Placed In-Service increased approximately $1.8 million and Properties Repositioned increased approximately $1.3 million.

Operating expenses from the Same Property Portfolio increased approximately $15.3 million for the six months ended June 30, 2007 compared to 2006. Included in Same Property Portfolio operating expenses is an increase in utility expenses of approximately $1.9 million, which represents an increase of approximately 4% over the prior year. In addition, real estate taxes increased approximately $4.9 million, a 6% increase due to increased real estate tax assessments.

The acquisitions of 6601 & 6605 Springfield Center Drive, 103 Fourth Avenue, Springfield Metro Center and Kingstowne Towne Center during the six months ended June 30, 2007, as well as the acquisitions during 2006, increased operating expenses from Properties Acquired by approximately $6.6 million for the six months ended June 30, 2007 as detailed below:

We continue to review and monitor the impact of rising insurance and energy costs, as well as other factors, on our operating budgets for fiscal year 2007. Because some operating expenses are not recoverable from tenants, an increase in operating expenses due to one or more of the foregoing factors could have an adverse effect on our results of operations.

Hotel Net Operating Income

Net operating income for the Cambridge Center Marriott hotel property increased approximately $0.9 million for the six months ended June 30, 2007 as compared to 2006. For the six months ended June 30, 2007 and 2006, the operations of the Long Wharf Marriott has been included as part of discontinued operations due to its sale on March 23, 2007. We expect the Cambridge hotel to contribute between $9.0 million and $9.5 million to net operating income for 2007, an increase of approximately 13% over 2006.

The following reflects our occupancy and rate information for the Cambridge Center Marriott hotel for the six months ended June 30, 2007 and 2006. For the six months ended June 30, 2006, our hotel underwent a room renovation project which totaled approximately $5.6 million.

Development and Management Services

Development and Management Services income increased approximately $0.3 million for the six months ended June 30, 2007 compared to 2006. We have maintained management contracts following the sale of 5 Times Square on February 15, 2007 and 280 Park Avenue on June 6, 2006. As we complete our joint venture project at 505 9th Street and several large tenant improvement projects we expect development and management fee income to decrease.

Interest and Other Income

Interest and other income increased approximately $32.7 million for the six months ended June 30, 2007 compared to 2006 as a result of higher overall interest rates and increased average cash balances. In February 2007, we issued $862.5 million of unsecured exchangeable senior notes. On February 15, 2007, we completed the sale of our long-term leasehold interest in 5 Times Square in New York City for approximately $1.28 billion in cash. On March 23, 2007, we completed the sale of the Long Wharf Marriott for approximately $225.6 million in cash and on April 5, 2007 we completed the sale of Newport Office Park for approximately $33.7 million in cash. The sale of our Long Wharf Marriott hotel was completed as part of a “like-kind exchange” under Section 1031 of the Internal Revenue Code.

Table of Contents

We expect that our aggregate distributions for the 2007 tax year will include, in addition to our regular quarterly distributions, at least that portion of the 2007 property sale proceeds necessary for us to avoid paying corporate level tax on the otherwise taxable gain. As our development activities intensify, the amount of our cash invested in these assets will result in a corresponding reduction in our interest income as well as in increase in our capitalized interest expense.

Other Expenses

General and Administrative

General and administrative expenses increased approximately $2.7 million for the six months ended June 30, 2007 compared to 2006 due to a full run rate on our stock based compensation and increases in base compensation. During the six months ended June 30, 2007 we recognized additional expense related to abandoned project costs and moving expenses related to the relocation of our corporate office. We anticipate our general and administrative expenses to be approximately $17.0 million each quarter for the year 2007. With the increased development activity in 2007 and into 2008, we expect capitalized wages to increase.

Commencing in 2003, we issued restricted stock and/or LTIP Units, as opposed to granting stock options and restricted stock, under the 1997 Stock Option and Incentive Plan as our primary vehicle for employee equity compensation. An LTIP Unit is generally the economic equivalent of a share of our restricted stock. Employees vest in restricted stock and LTIP Units over a four- or five-year term (for awards granted between 2003 and November 2006, vesting is over a five-year term with annual vesting of 0%, 0%, 25%, 35% and 40%; and for awards granted after November 2006, vesting will occur in equal annual installments over a four-year term). Restricted stock and LTIP Units are valued based on observable market prices for similar instruments. Such value is recognized as an expense ratably over the corresponding employee service period. LTIP Units that were issued in January 2005 and any future LTIP Unit awards will be valued using an option pricing model in accordance with the provisions of SFAS No. 123R. To the extent restricted stock or LTIP Units are forfeited prior to vesting, the corresponding previously recognized expense is reversed as an offset to “stock-based compensation.” Stock-based compensation associated with approximately $11.3 million of restricted stock and LTIP Units granted in April 2006 and approximately $18.5 million of restricted stock and LTIP Units granted in January 2007 will be incurred ratably as such restricted stock and LTIP Units vest.

Interest Expense

Interest expense for the Total Property Portfolio decreased approximately $5.6 million for the six months ended June 30, 2007 compared to 2006. The decrease is due to (1) the repayment of outstanding mortgage debt in connection with the sale of 280 Park Avenue in June 2006 which decreased interest expense by $8.4 million, (2) the repayment of our mortgage loans collateralized by Capital Gallery, 191 Spring Street, 101 Carnegie Center, Seven Cambridge Center and Embarcadero Center Three, which decreased interest expense approximately $8.0 million, and (3) an increase in capitalized interest costs which results in a decrease of interest expense of approximately $5.8 million. These decreases were offset by (1) an increase of approximately $4.5 million related to interest paid on the $450 million unsecured exchangeable senior notes issued in the second quarter of 2006 at a per annum interest rate of 3.75%, (2) an increase of approximately $11.7 million related to interest paid on the $862.5 million unsecured exchangeable senior notes issued in the first quarter of 2007 at an effective per annum interest rate of 3.438% and (3) an increase of approximately $1.0 million related to the acquisition of Kingstowne Towne Center on March 30, 2007. The remaining decrease is attributed to scheduled loan amortization on our outstanding debt.

Depreciation and Amortization

Depreciation and amortization expense for the Total Property Portfolio increased approximately $9.8 million for the six months ended June 30, 2007 compared to 2006. Approximately $5.5 million related to increases in the Same Property Portfolio and approximately $11.3 million related to the recent acquisition activity. An increase of approximately $0.7 million was due to the placing in-service of our Seven Cambridge Center development project in the first quarter of 2006 and our 12290 Sunrise Valley development project in the second quarter of 2006 and approximately $1.0 million was attributed to Properties Repositioned. These increases were offset by a decrease of approximately $8.8 million due to the sales of 5 Times Square in February 2007 and 280 Park Avenue in June 2006.

Capitalized Costs

Costs directly related to the development of rental properties are not included in our operating results. These costs are capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over their useful lives. Capitalized development costs include interest, wages, property taxes, insurance and other project costs incurred during the period of development. Capitalized wages for the six months ended June 30, 2007 and 2006 were $5.1 million and $2.9 million, respectively. These costs are not included in the general and administrative expenses discussed above. We expect capitalized wages to increase proportionately with our increased development activity into 2007 and 2008. Interest capitalized for the six months ended June 30, 2007 and 2006 was $12.3 million and $3.0 million, respectively. These costs are not included in the interest expense referenced above.

Losses from early extinguishments of debt

On February 12, 2007, we refinanced our mortgage loan collateralized by 599 Lexington Avenue located in New York City. The new mortgage financing totaling $750.0 million bears interest at a fixed interest rate of 5.57% per annum and matures on March 1, 2017. The net proceeds of the new loan were used to refinance the $225.0 million mortgage loan on 599 Lexington Avenue and the $475.0 million mortgage loan on Times Square Tower. In connection with the refinancing, the lien of the Times Square Tower mortgage was spread to

599 Lexington Avenue and released from Times Square Tower so that Times Square Tower is no longer encumbered by any mortgage debt. There was no prepayment penalty associated with the repayment. The Company recognized a loss from early extinguishment of debt totaling approximately $0.7 million consisting of the write-off of unamortized deferred financing costs.

For the six months ended June 30, 2006, we repaid the construction financing collateralized by our Seven Cambridge Center property and, in connection with the sale of 280 Park Avenue, we legally defeased the mortgage indebtedness collateralized by 280 Park Avenue totaling approximately $254.4 million. In connection with the defeasance of mortgage indebtedness at 280 Park Avenue we recognized a loss from early extinguishment of debt totaling approximately $31.4 million consisting of the difference between the value of the U.S. Treasuries and the principal balance of the mortgage loan totaling approximately $28.2 million and the write-off of unamortized deferred financing costs totaling approximately $3.2 million. The construction financing at Seven Cambridge Center totaling approximately $112.5 million was repaid using approximately $7.5 million of available cash and $105.0 million drawn under our Unsecured Line of Credit. There was no prepayment penalty associated with the repayment for Seven Cambridge Center. We recognized losses from early extinguishments of debt totaling approximately $0.5 million consisting of the write-off of unamortized deferred financing costs.

Income from Unconsolidated Joint Ventures

For the six months ended June 30, 2007, income from unconsolidated joint ventures increased approximately $15.3 million. On June 1, 2007, our Value-Added Fund sold Worldgate Plaza located in Herndon, Virginia for approximately $109.0 million. Worldgate Plaza is an office complex consisting of approximately 322,000 net rentable square feet. Net cash proceeds totaled approximately $50.5 million, of which our share was approximately $20.3 million, after the repayment of the mortgage indebtedness of $57.0 million. Our share of the gain is included as income in joint ventures was approximately $15.5 million which amount reflects the achievement of certain return thresholds as provided for in the joint venture agreement.

Our joint venture project at 505 9th Street is expected to be placed in-service during the third quarter of 2007. We have a 50% interest in this project.

Income from discontinued operations

For the six months ended June 30, 2007 and June 30, 2006, the properties included in discontinued operations consisted of our Long Wharf Marriott hotel in Boston, Massachusetts and Newport Office Park in Quincy, Massachusetts.

Minority interest in property partnership

Minority interest in property partnership consisted of the outside equity interests in the venture that owned Citigroup Center. This venture was consolidated with our financial results because we exercised control over the entity. Due to the redemption of the minority interest holder at Citigroup Center on May 31, 2006, minority interest in property partnership no longer reflects an allocation to the minority interest holder.

Gains on sales of real estate

On February 15, 2007, we sold the long-term leasehold interest in 5 Times Square in New York City and related credits, for approximately $1.28 billion in cash. Net cash proceeds totaled approximately $1.23 billion, resulting in a gain on sale of approximately $713.6 million. In conjunction with the sale, we have agreed to provide to the buyer monthly revenue support from the closing date until December 31, 2008. The aggregate amount of the revenue support payments was approximately $1.6 million and has been recorded as a purchase

price adjustment and included in Other Liabilities within our Consolidated Balance Sheets. As of June 30, 2007, the revenue support obligation totaled approximately $0.4 million.

During the six months ended June 30, 2007, we signed a new qualifying lease for approximately 22,000 net rentable square feet of our remaining 47,659 net rentable square foot master lease obligation related to the 2006 sale of 280 Park Avenue resulting in the recognition of approximately $18.0 million as additional gain on sale of real estate. We had deferred approximately $67.3 million of the gain on sale of 280 Park Avenue, which amount represented the maximum obligation under the master lease. As of June 30, 2007, the remaining master lease obligation totaled approximately $26.9 million.

On June 6, 2006, we sold 280 Park Avenue, a 1,179,000 net rentable square foot Class A office property located in midtown Manhattan, New York, for approximately $1.2 billion. Net proceeds totaled approximately $875 million after legal defeasance of indebtedness secured by the property (consisting of approximately $254.4 million of principal indebtedness and approximately $28.2 million of related defeasance costs) and the payment of transfer taxes, brokers’ fees and other customary closing costs. We recognized a gain on sale of approximately $691.1 million. In January 2006 we recognized a gain on the sale of a parcel of land at the Prudential Center located in Boston, Massachusetts which had been accounted for previously as a financing transaction. During January 2006, the transaction qualified as a sale for financial reporting purposes.

Gains on sales of real estate from discontinued operations

On March 23, 2007, we sold the Long Wharf Marriott, a 402-room hotel located in Boston, Massachusetts, for approximately $231.0 million. Net cash proceeds totaled approximately $225.6 million, resulting in a gain on sale of approximately $194.4 million. On April 5, 2007, we sold Newport Office Park, an approximately 172,000 net rentable square foot Class A office property located in Quincy, Massachusetts, for approximately $37.0 million. Net cash proceeds totaled approximately $33.7 million, resulting in a gain on sale of approximately $14.3 million.

Comparison of the three months ended June 30, 2007 to the three months ended June 30, 2006.

The table below shows selected operating information for the Same Property Portfolio and the Total Property Portfolio. The Same Property Portfolio consists of 114 properties totaling approximately 28.6 million net rentable square feet of space. The Same Property Portfolio includes properties acquired or placed in-service on or prior to April 1, 2006 and owned through June 30, 2007. In addition, the Same Property Portfolio includes our Cambridge Center Marriott hotel property, but does not include the Long Wharf Marriott hotel property, which was sold on March 23, 2007. The Total Property Portfolio includes the effects of the other properties either placed in-service, acquired or repositioned after April 1, 2006 or disposed of on or prior to June 30, 2007. This table includes a reconciliation from the Same Property Portfolio to the Total Property Portfolio by also providing information for the three months ended June 30, 2007 and 2006 with respect to the properties which were acquired, placed in-service, repositioned or sold.

During July 2006, we placed in-service our Capital Gallery expansion project, consisting of a ten-story addition totaling approximately 319,000 net rentable square feet of Class A office space located in Washington, D.C. The project entailed removing a three-story, low-rise section of the property from in-service status and developing it into a ten-story office building resulting in a total complex size of approximately 615,000 net rentable square feet. In April 2006, tenants began to take initial occupancy. This property is included in Properties Repositioned for the three months ended June 30, 2007 and June 30, 2006.

Rental Revenue

The decrease of approximately $0.7 million in the Total Property Portfolio is comprised of increases and decreases within the five categories that comprise our Total Property Portfolio. Rental revenue from the Same Property Portfolio increased approximately $17.9 million, Properties Sold decreased approximately $32.5 million, Properties Acquired increased approximately $12.5 million and Properties Repositioned increased approximately $1.4 million.

We incur certain tenant specific property costs for which we are reimbursed from our tenants. Starting in 2007, we have included these reimbursements in rental revenue and included the tenant specific operating cost within real estate operating expenses. This income and expense classification in 2007 results in a presented increase to comparable rental revenue and real estate operating expenses, however does not impact our consolidated net operating income. For the three months ended June 30, 2007 and 2006, the rental income and real estate operating expense gross up was approximately $2.2 million and $2.5 million, respectively.

Rental revenue from the Same Property Portfolio increased approximately $17.9 million for the three months ended June 30, 2007 compared to 2006. Included in rental revenue is an overall increase in base rental revenue of approximately $10.8 million. Approximately $7.3 million of the increase from the Same Property Portfolio was due to an increase in recoveries from tenants which correlates with the increase in operating expenses. We collected almost $2.0 million in connection with a modification to the calculation of a tenant’s real estate tax operating expense obligation from a lease that commenced in 1999 and was adjusted for the last six years. We expect occupancy to remain level and same property net operating income to grow approximately 3% over our same property net operating income in 2006. In addition, we expect straight-line rents and FAS 141 adjustments for the remainder of 2007 to contribute between $8 million and $10 million to rental revenue per quarter.

The acquisitions of 6601 & 6605 Springfield Center Drive, 103 Fourth Avenue and Kingstowne Towne Center during 2007 as well as the acquisitions during 2006 increased rental revenue from Properties Acquired by approximately $12.5 million for the three months ended June 30, 2007 as detailed below:

The aggregate increase in rental revenue was offset by the sales of 5 Times Square in February 2007 and 280 Park Avenue in June 2006. These properties have not been classified as discontinued operations due to our continuing involvement as the property manager for each property. Rental Revenue from Properties Sold decreased by approximately $32.5 million, as detailed below:

Termination Income

Termination income for the three months ended June 30, 2007 was related to six tenants across the Total Property Portfolio that terminated their leases, and we recognized termination income totaling approximately $0.7 million. This compared to termination income of approximately $1.4 million for the three months ended June 30, 2006 related to seven tenants. We currently anticipate realizing approximately $1.0 million in termination income per quarter for the remainder of 2007.

Real Estate Operating Expenses

The $3.9 million increase in property operating expenses (real estate taxes, utilities, insurance, repairs and maintenance, cleaning and other property-related expenses) in the Total Property Portfolio is comprised of increases and decreases within five categories that comprise our Total Property Portfolio. Operating expenses for the Same Property Portfolio increased approximately $9.2 million, Properties Sold decreased approximately $9.6 million, Properties Acquired increased approximately $3.8 million and Properties Repositioned increased approximately $0.5 million.

We incur certain tenant specific property costs for which we are reimbursed from our tenants. Starting in 2007, we have included these reimbursements in rental revenue and included the tenant specific operating cost within real estate operating expenses. This income and expense classification in 2007 results in a presented increase to comparable rental revenue and real estate operating expenses, however does not impact our consolidated net operating income.

Operating expenses from the Same Property Portfolio increased approximately $9.2 million for the three months ended June 30, 2007 compared to 2006. Included in Same Property Portfolio operating expenses is an increase in utility expenses of approximately $1.3 million, which represents an increase of approximately 7% over the prior year second quarter. In addition, real estate taxes increased approximately $3.7 million, a 10% increase due to increased real estate tax assessments, and approximately $3.6 million increase in repairs and maintenance and other administrative property expenses.

In April 2006, tenants began to take occupancy and we placed our Capital Gallery expansion project in-service in July 2006.

A decrease of approximately $9.6 million in the Total Property Portfolio operating expenses was due to the sales of 5 Times Square in February 2007 and 280 Park Avenue in June 2006, as detailed below:

We continue to review and monitor the impact of rising insurance and energy costs, as well as other factors, on our operating budgets for fiscal year 2007. Because some operating expenses are not recoverable from tenants, an increase in operating expenses due to one or more of the foregoing factors could have an adverse effect on our results of operations.

Hotel Net Operating Income

Net operating income for the Cambridge Center Marriott hotel property increased approximately $0.1 million for the three months ended June 30, 2007 as compared to 2006. For the three months ended June 30, 2007 and 2006, the operations of the Long Wharf Marriott has been included as part of discontinued operations due to its sale on March 23, 2007. We expect the Cambridge hotel to contribute between $9.0 million and $9.5 million to net operating income for 2007, an increase of approximately 13% over 2006.

The following reflects our occupancy and rate information for the Cambridge Center Marriott hotel for the three months ended June 30, 2007 and 2006. For the six months ended June 30, 2006, our hotel underwent a room renovation project which totaled approximately $5.6 million.

Development and Management Services

Development and Management Services income decreased approximately $0.1 million for the three months ended June 30, 2007 compared to 2006. We have maintained management contracts following the sale of 5 Times Square on February 15, 2007 and 280 Park Avenue on June 6, 2006. As we complete our joint venture project at 505 9th Street and several large tenant improvement projects we expect development and management fee income to decrease.

Interest and Other Income

Interest and other income increased approximately $17.7 million for the three months ended June 30, 2007 compared to 2006 as a result of higher overall interest rates and increased average cash balances. In February 2007, we issued $862.5 million of unsecured exchangeable senior notes. On February 15, 2007, we completed the sale of our long-term leasehold interest in 5 Times Square in New York City for approximately $1.28 billion in cash. On March 23, 2007, we completed the sale of the Long Wharf Marriott for approximately $225.6 million in cash and, on April 5, 2007, we completed the sale of Newport Office Park for approximately $33.7 million in cash. The sale of our Long Wharf Marriott hotel was completed as part of a “like-kind exchange” under Section 1031 of the Internal Revenue Code.

We expect that our aggregate distributions for the 2007 tax year will include, in addition to our regular quarterly distributions, at least that portion of the 2007 property sale proceeds necessary for us to avoid paying corporate level tax on the otherwise taxable gain. As our development activities intensify, the amount of our cash invested in these assets will result in a corresponding reduction in our interest income as well as in increase in our capitalized interest expense.

Other Expenses

General and Administrative

General and administrative expenses increased approximately $0.5 million for the three months ended June 30, 2007 compared to 2006 due to a full run rate on our stock based compensation and increases in base compensation. During the six months ended June 30, 2007 we recognized additional expense related to abandoned project costs and moving expenses related to the relocation of our corporate office. We anticipate our general and administrative expenses to be approximately $17.0 million each quarter for the year 2007. With the increased development activity in 2007 and into 2008, we expect capitalized wages to increase.

Commencing in 2003, we issued restricted stock and/or LTIP Units, as opposed to granting stock options and restricted stock, under the 1997 Stock Option and Incentive Plan as our primary vehicle for employee equity compensation. An LTIP Unit is generally the economic equivalent of a share of our restricted stock. Employees vest in restricted stock and LTIP Units over a four- or five-year term (for awards granted between 2003 and November 2006, vesting is over a five-year term with annual vesting of 0%, 0%, 25%, 35% and 40%; and for awards granted after November 2006, vesting will occur in equal annual installments over a four-year term). Restricted stock and LTIP Units are valued based on observable market prices for similar instruments. Such

value is recognized as an expense ratably over the corresponding employee service period. LTIP Units that were issued in January 2005 and any future LTIP Unit awards will be valued using an option pricing model in accordance with the provisions of SFAS No. 123R. To the extent restricted stock or LTIP Units are forfeited prior to vesting, the corresponding previously recognized expense is reversed as an offset to “stock-based compensation.” Stock-based compensation associated with approximately $11.3 million of restricted stock and LTIP Units granted in April 2006 and approximately $18.5 million of restricted stock and LTIP Units granted in January 2007 will be incurred ratably as such restricted stock and LTIP Units vest.

Interest Expense

Interest expense for the Total Property Portfolio decreased approximately $4.7 million for the three months ended June 30, 2007 compared to 2006. The decrease is due to (1) the repayment of outstanding mortgage debt in connection with the sale of 280 Park Avenue in June 2006 which decreased interest expense by $3.6 million, (2) the repayment of our mortgage loans collateralized by Capital Gallery, 191 Spring Street and Embarcadero Center Three, which decreased interest expense approximately $3.7 million, and (3) an increase in capitalized interest costs which results in a decrease of interest expense of approximately $6.6 million. These decreases were offset by (1) an increase of approximately $7.2 million related to interest paid on the $862.5 million unsecured exchangeable senior notes issued in the first quarter of 2007 at an effective per annum interest rate of 3.438% and (2) an increase of approximately $1.0 million related to the acquisition of Kingstowne Towne Center on March 30, 2007. The remaining decrease is attributed to scheduled loan amortization on our outstanding debt.

At June 30, 2007, our variable rate debt consisted of our construction loan at South of Market. The following summarizes our outstanding debt as of June 30, 2007 and June 30, 2006:

Depreciation and Amortization

Depreciation and amortization expense for the Total Property Portfolio increased approximately $6.5 million for the three months ended June 30, 2007 compared to 2006. Approximately $3.0 million related to increases in the Same Property Portfolio and approximately $6.5 million related to the recent acquisition activity. An increase of approximately $0.4 million was attributed to Properties Repositioned. These increases were offset by a decrease of approximately $3.3 million due to the sales of 5 Times Square in February 2007 and 280 Park Avenue in June 2006.

Capitalized Costs

Costs directly related to the development of rental properties are not included in our operating results. These costs are capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over their useful lives. Capitalized development costs include interest, wages, property taxes, insurance and other project costs incurred during the period of development. Capitalized wages for the three months ended June 30, 2007 and 2006 were $2.8 million and $1.5 million, respectively. These costs are not included in the general and administrative expenses discussed above. We expect capitalized wages to increase proportionately with our increased development activity into 2007 and 2008. Interest capitalized for the three months ended June 30, 2007 and 2006 was $7.9 million and $1.3 million, respectively. These costs are not included in the interest expense referenced above.

Losses from early extinguishments of debt

In connection with the defeasance of mortgage indebtedness at 280 Park Avenue in June 2006, we recognized a loss from early extinguishment of debt totaling approximately $31.4 million consisting of the difference between the value of the U.S. Treasuries and the principal balance of the mortgage loan totaling approximately $28.2 million and the write-off of unamortized deferred financing costs totaling approximately $3.2 million.

Income from Unconsolidated Joint Ventures

For the three months ended June 30, 2007, income from unconsolidated joint ventures increased approximately $15.6 million. On June 1, 2007, our Value-Added Fund sold Worldgate Plaza located in Herndon, Virginia for approximately $109.0 million. Worldgate Plaza is an office complex consisting of approximately 322,000 net rentable square feet. Net cash proceeds totaled approximately $50.5 million, of which our share was approximately $20.3 million, after the repayment of the mortgage indebtedness of $57.0 million. Our share of the gain is included as income in joint ventures was approximately $15.5 million which amount reflects the achievement of certain return thresholds as provided for in the joint venture agreement.

Our joint venture project at 505 9th Street is expected to be placed in-service during the third quarter of 2007. We have a 50% interest in this project.

Income from discontinued operations

For the three months ended June 30, 2007, discontinued operations consisted of our Newport Office Park in Quincy, Massachusetts. For the three months ended June 30, 2006, the properties included in discontinued operations consisted of our Long Wharf Marriott Hotel in Boston, Massachusetts and Newport Office Park in Quincy, Massachusetts.

Minority interest in property partnership

Minority interest in property partnership consisted of the outside equity interests in the venture that owned Citigroup Center. This venture was consolidated with our financial results because we exercised control over the entity. Due to the redemption of the minority interest holder at Citigroup Center on May 31, 2006, minority interest in property partnership no longer reflects an allocation to the minority interest holder.

Gains on sales of real estate

On June 6, 2006, we sold 280 Park Avenue, a 1,179,000 net rentable square foot Class A office property located in midtown Manhattan, New York, for approximately $1.2 billion. Net proceeds totaled approximately $875 million after legal defeasance of indebtedness secured by the property (consisting of approximately $254.4 million of principal indebtedness and approximately $28.2 million of related defeasance costs) and the

payment of transfer taxes, brokers’ fees and other customary closing costs. We recognized a gain on sale of approximately $698.4 million.

Gains on sales of real estate from discontinued operations

On April 5, 2007, we sold Newport Office Park, an approximately 172,000 net rentable square foot Class A office property located in Quincy, Massachusetts, for approximately $37.0 million. Net cash proceeds totaled approximately $33.7 million, resulting in a gain on sale of approximately $14.3 million.

Liquidity and Capital Resources

General

Our principal liquidity needs for the next twelve months are to:

 

   

fund normal recurring expenses;

 

   

fund current development costs not covered under construction loans;

 

   

meet debt service requirements;

 

   

fund capital expenditures, including tenant improvements and leasing costs;

 

   

fund new property acquisitions; and

 

   

make the minimum distribution required to maintain Boston Properties, Inc.’s REIT qualification under the Internal Revenue Code of 1986, as amended.

On December 15, 2006, the Board of Directors of Boston Properties, Inc. declared a special cash distribution of $5.40 per common share payable on January 30, 2007 to holders of record of common units and LTIP units as of the close of business on December 29, 2006. The decision to declare a special distribution was the result of the sales of assets in 2006, including 280 Park Avenue and 265 Franklin Street. The Board of Directors of Boston Properties, Inc. did not make any change in its policy with respect to regular quarterly distributions. The payment of the regular quarterly distribution of $0.68 per share and the special distribution of $5.40 per share resulted in a total payment of $6.08 per share on January 30, 2007.

We expect that our aggregate distributions for the 2007 tax year will include, in addition to our regular quarterly distributions, at least that portion of 2007 property sale proceeds necessary for us to avoid paying corporate level tax on the otherwise taxable gain, currently estimated to be approximately $810 million. Under applicable tax rules, distributions for the 2007 tax year must be paid by January 30, 2008.

We repaid the mortgage secured by our Embarcadero Center Four on August 6, 2007, and anticipate repaying the mortgages secured by the 500 Series at Carnegie Center in October 2007, prior to their natural maturities. These repayments do not have any prepayment penalties and will utilize approximately $197 million of cash.

We believe that our liquidity needs will be satisfied using cash on hand, cash flows generated by operations and provided by financing activities, as well as cash generated from asset sales. Base rental revenue, recovery income from tenants, other income from operations, available cash balances, draws on our unsecured line of credit and refinancing of maturing indebtedness are our principal sources of capital used to pay operating expenses, debt service, recurring capital expenditures and the minimum distribution required to maintain Boston Properties, Inc.’s REIT qualification. We seek to increase income from our existing properties by maintaining quality standards for our properties that promote high occupancy rates and permit increases in rental rates while reducing tenant turnover and controlling operating expenses. Our sources of revenue also include third-party fees generated by our office real estate management, leasing, development and construction businesses. Consequently, we believe our revenue, together with proceeds from financing activities, will continue to provide

 

52


Table of Contents

the necessary funds for our short-term liquidity needs. However, material changes in these factors may adversely affect our net cash flows. Such changes, in turn, could adversely affect our ability to fund distributions, debt service payments and tenant improvements. In addition, a material adverse change in our cash provided by operations may affect our ability to comply with the financial performance covenants under our unsecured line of credit and unsecured senior notes.

Our principal liquidity needs for periods beyond twelve months are for the costs of developments, possible property acquisitions, scheduled debt maturities, major renovations, expansions and other non-recurring capital improvements. We expect to satisfy these needs using one or more of the following:

 

   

construction loans;

 

   

long-term secured and unsecured indebtedness (including unsecured exchangeable indebtedness);

 

   

income from operations;

 

   

income from joint ventures;

 

   

sales of real estate;

 

   

proceeds from the issuance of equity securities of Boston Properties, Inc. and/or additional preferred or common units of partnership interests; and

 

   

our unsecured revolving line of credit or other short-term bridge facilities.

We draw on multiple financing sources to fund our long-term capital needs. Our unsecured line of credit is utilized primarily as a bridge facility to fund acquisition opportunities, to refinance outstanding indebtedness and to meet short-term development and working capital needs. We generally fund our development projects with construction loans that we may partially guaranteed until project completion or lease-up thresholds are achieved.

To the extent that we continue to sell assets and cannot efficiently use the proceeds for either our development activities or attractive acquisitions, we would, at the appropriate time, decide whether it is better to declare a special dividend, adopt a stock repurchase program, reduce our indebtedness or retain the cash for future investment opportunities. Such a decision will depend on many factors including, among others, the timing, availability and terms of development and acquisition opportunities, our then-current and anticipated leverage, the price of Boston Properties, Inc.’s common stock and REIT distribution requirements. At a minimum, we expect that we would distribute at least that amount of proceeds necessary for us to avoid paying corporate level tax on the applicable gains realized from any asset sales.

Cash Flow Summary

The following summary discussion of our cash flows is based on the consolidated statements of cash flows and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below.

Cash and cash equivalents were $1.9 billion and $370.4 million at June 30, 2007 and 2006, respectively, representing an increase of $1.5 billion. The increase in cash and cash equivalents was mainly attributed to net proceeds from the sale of 5 Times Square in New York City and Long Wharf Marriott and proceeds from our offering of unsecured exchangeable senior notes offset by dividends and distributions. The following table sets forth increases and decreases in cash flows:

 

     Six months ended June 30

     (29,957 )     105,911       (135,868 )

 

53


Table of Contents

Our principal source of cash flow is related to the operation of our office properties. The average term of our tenant leases is approximately 7.3 years with occupancy rates historically in the range of 92% to 98%. Our properties provide a relatively consistent stream of cash flow that provides us with resources to pay operating expenses, debt service and fund quarterly dividend and distribution payment requirements. In addition, over the past two years, we have raised capital through the sale of some of our properties and raised proceeds from secured and unsecured borrowings.

In 2007, we expect our total distributions to exceed our cash flow from operating activities due to the special distribution which was declared in December 2006 and paid to common unitholders of BPLP on January 30, 2007. The cash flows distributed were generated from sales of real estate assets and which proceeds are included as part of cash flows from investment activities. Distributions will generally exceed cash flows from operating activities during periods in which we sell significant real estate assets and distribute gains on sale that would otherwise be taxable.

Cash is used in investing activities to fund acquisitions, development and recurring and nonrecurring capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing and property management skills and invest in existing buildings that meet our investment criteria. Cash provided by investing activities for the six months ended June 30, 2007 consisted of the following:

 

     Six months ended
June 30, 2007
 
     (in thousands)  

Net proceeds from the sales of real estate

Planned non-recurring capital expenditures associated with acquisition properties

     (658 )
        

Net cash provided by investing activities

   $ 877,631  
        

Cash used in financing activities for the six months ended June 30, 2007 totaled approximately $30.0 million. This consisted primarily of the $840 million of net proceeds from our exchangeable unsecured senior notes offering and proceeds from mortgage notes payable, offset by the repayment of our Times Square Tower mortgage loan, our secured draw under our Unecured Line of Credit, as well as the payments of dividends and distributions to unitholders. Future debt payments are discussed below under the heading “Debt Financing.”

Capitalization

At June 30, 2007, our total consolidated debt was approximately $5.6 billion. The weighted-average annual interest rate on our consolidated indebtedness was 5.72% and the weighted-average maturity was approximately 5.4 years.

Debt to total market capitalization ratio, defined as total consolidated debt as a percentage of the market value of our outstanding equity securities plus our total consolidated debt, is a measure of leverage commonly used by analysts in the REIT sector. Our total market capitalization was approximately $20.1 billion at June 30, 2007. Total market capitalization was calculated using Boston Properties, Inc.’s June 30, 2007 closing stock price of $102.13 per common share and the following: (1) 119,028,081 outstanding common units of BPLP held by Boston Properties, Inc., (2) 20,285,414 outstanding OP Units held by persons other than Boston Properties, Inc., (3) an aggregate of 1,676,461 OP Units issuable upon conversion of all outstanding preferred units, (4) an aggregate of 676,752 OP Units issuable upon conversion of all outstanding LTIP units, assuming all conditions have been met for the conversion of the LTIP units, and (5) our consolidated debt totaling approximately

 

54


Table of Contents

$5.6 billion. Our total consolidated debt at June 30, 2007 represented approximately 27.98% of our total market capitalization. This percentage will fluctuate with changes in the market price of Boston Properties, Inc.’s common stock and does not necessarily reflect our capacity to incur additional debt to finance our activities or our ability to manage our existing debt obligations. However, for a company like ours, whose assets are primarily income-producing real estate, the debt to total market capitalization ratio may provide investors with an alternate indication of leverage, so long as it is evaluated along with other financial ratios and the various components of our outstanding indebtedness.

Debt Financing

As of June 30, 2007, we had approximately $5.6 billion of outstanding indebtedness, representing 27.98% of our total market capitalization as calculated above consisting of (1) $1.472 billion in publicly traded unsecured debt having a weighted average interest rate of 5.95% per annum and maturities in 2013 and 2015; (2) $450 million of publicly traded exchangeable unsecured debt having an interest rate of 3.75% per annum, an initial optional redemption date in 2013 and maturity in 2036; (3) $862.5 million of publicly traded exchangeable unsecured debt having an interest rate of 2.875% per annum (an effective rate of 3.438% per annum) having an initial optional redemption in 2012 and maturing in 2037; and (4) $2.9 billion of property-specific mortgage debt having a weighted average interest rate of 6.59% per annum and weighted average term of 4.97 years.

Unsecured Line of Credit

On August 3, 2006, we modified our $605.0 million unsecured revolving credit facility (the “Unsecured Line of Credit”) by extending the maturity date from October 30, 2007 to August 3, 2010, with a provision for a one-year extension at our option, subject to certain conditions, and by reducing the per annum variable interest

Table of Contents

rate on outstanding balances from Eurodollar plus 0.65% to Eurodollar plus 0.55% per annum. Effective March 22, 2007, the per annum variable interest rate was reduced to Eurodollar plus 0.475% and the facility fee, which is payable in equal quarterly installments, was reduced from 15 basis points to 12.5 basis points per annum as a result of an increase in our unsecured debt rating. The Unsecured Line of Credit involves a syndicate of lenders. The Unsecured Line of Credit contains a competitive bid option that allows banks that are part of the lender consortium to bid to make loan advances to the Company at a reduced Eurodollar rate. The Unsecured Line of Credit will be available to fund working capital and general corporate purposes, including, without limitation, to fund development of properties, land and property acquisitions and to repay or reduce indebtedness. The Unsecured Line of Credit is a recourse obligation of Boston Properties Limited Partnership.

Our ability to borrow under our Unsecured Line of Credit is subject to our compliance with a number of customary financial and other covenants on an ongoing basis, including:

 

   

a leverage ratio not to exceed 60%, however the leverage ratio may increase to no greater than 65% provided that it is reduced back to 60% within 180 days;

 

   

a secured debt leverage ratio not to exceed 55%;

 

   

a fixed charge coverage ratio of at least 1.40;

 

   

an unsecured leverage ratio not to exceed 60%, however the leverage ratio may increase to no greater than 65% provided that it is reduced back to 60% within 180 days;

 

   

a minimum net worth requirement;

 

   

an unsecured debt interest coverage ratio of at least 1.75; and

 

   

limitations on permitted investments.

We believe we are in compliance with the financial and other covenants listed above.

As of June 30, 2007, we had no amount outstanding under the Unsecured Line of Credit with the ability to borrow $583.4 million. We currently have no borrowings outstanding under our Unsecured Line of Credit.

The indenture under which our senior unsecured notes were issued contains restrictions on incurring debt and using our assets as security in other financing transactions and other customary financial and other covenants, including (1) a leverage ratio not to exceed 60%, (2) a secured debt leverage ratio not to exceed 50%, (3) an interest coverage ratio of 1.5, and (4) unencumbered asset value to be no less than 150% of our unsecured debt. As of June 30, 2007, we were in compliance with each of these financial restrictions and requirements.

Our investment grade ratings on its unsecured senior notes are as follows:

 

Rating Organization

  

Rating

Moody’s    Baa2 (stable)
Standard & Poor’s    BBB+ (stable)
FitchRatings    BBB (stable)

The security rating is not a recommendation to buy, sell or hold securities, as it may be subject to revision or withdrawal at any time by the rating organization. Each rating should be evaluated independently of any other rating. On March 21, 2007, Standard & Poor’s raised our senior unsecured credit ratings from BBB to BBB+, the outlook remaining stable.

Unsecured exchangeable senior notes

3.75% Exchangeable Senior Notes due 2036

On April 6, 2006, we completed a public offering of $400 million in aggregate principal amount of our 3.75% exchangeable senior notes due 2036. On May 2, 2006, we issued an additional $50 million aggregate principal amount of the notes as a result of the exercise by the underwriter of its over-allotment option. The notes mature on May 15, 2036, unless earlier repurchased, exchanged or redeemed.

Upon the occurrence of specified events, holders of the notes may exchange their notes prior to the close of business on the scheduled trading day immediately preceding May 18, 2013 into cash and, at our option, shares of Boston Properties, Inc.’s common stock at an exchange rate of 9.3900 shares per $1,000 principal amount of notes (or an exchange price of approximately $106.50 per share of Boston Properties, Inc.’s common stock). The initial exchange rate of 8.9461 shares per $1,000 principal amount of notes and the initial exchange price of approximately $111.78 per share of Boston Properties, Inc.’scommon stock were adjusted effective as of December 29, 2006 in connection with the special distribution declared on December 15, 2006. On and after May 18, 2013, the notes will be exchangeable at any time prior to the close of business on the scheduled trading day immediately preceding the maturity date at the option of the holder at the applicable exchange rate. The exchange rate is subject to adjustment in certain circumstances.

Prior to May 18, 2013, we may not redeem the notes except to preserve Boston Properties, Inc.’s status as a REIT. On or after May 18, 2013, we may redeem all or a portion of the notes for cash at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest. We must make at least 12 semi-annual interest payments (including interest payments on November 15, 2006 and May 15, 2013) before redeeming any notes at our option. Note holders may require us to repurchase all or a portion of the notes on May 18, 2013 and May 15 of 2016, 2021, 2026 and 2031 at a purchase price equal to 100% of the principal amount plus accrued and unpaid interest up to, but excluding, the repurchase date. We will pay cash for all notes so repurchased.

If we undergo a “fundamental change,” note holders will have the option to require us to purchase all or any portion of the notes at a purchase price equal to 100% of the principal amount of the notes to be purchased plus any accrued and unpaid interest to, but excluding, the fundamental change purchase date. We will pay cash for all notes so purchased. In addition, if a fundamental change occurs prior to May 18, 2013, we will increase the

2.875% Exchangeable Senior Notes due 2037

On February 6, 2007, we completed an offering of $862.5 million in aggregate principal amount (including $112.5 million as a result of the exercise by the initial purchasers of their over-allotment option) of our 2.875% exchangeable senior notes due 2037. The notes were priced at 97.433333% of their face amount, resulting in an effective interest rate of approximately 3.438% per annum and net proceeds to us of approximately $840.0 million. The notes mature on February 15, 2037, unless earlier repurchased, exchanged or redeemed.

Upon the occurrence of specified events, holders of the notes may exchange their notes prior to the close of business on the scheduled trading day immediately preceding February 20, 2012 into cash and, at our option, shares of Boston Properties, Inc.’s common stock at an initial exchange rate of 6.6090 shares per $1,000 principal amount of notes (or an initial exchange price of approximately $151.31 per share of Boston Properties, Inc.’s common stock). On and after February 20, 2012, the notes will be exchangeable at any time prior to the close of business on the scheduled trading day immediately preceding the maturity date at the option of the holder at the applicable exchange rate. The initial exchange rate is subject to adjustment in certain circumstances.

Prior to February 20, 2012, we may not redeem the notes except to preserve Boston Properties, Inc.’s status as a REIT. On or after February 20, 2012, we may redeem all or a portion of the notes for cash at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest. Note holders may require us to repurchase all or a portion of the notes on February 15 of 2012, 2017, 2022, 2027 and 2032 at a purchase price equal to 100% of the principal amount plus accrued and unpaid interest up to, but excluding, the repurchase date. We will pay cash for all notes so repurchased.

If we undergo a “fundamental change,” note holders will have the option to require us to purchase all or any portion of the notes at a purchase price equal to 100% of the principal amount of the notes to be purchased plus any accrued and unpaid interest to, but excluding, the fundamental change purchase date. We will pay cash for all notes so purchased. In addition, if a fundamental change occurs prior to February 20, 2012, we will increase the exchange rate for a holder who elects to exchange its notes in connection with such a fundamental change under certain circumstances.

We offered and sold the notes to the initial purchasers in reliance on the exemption from registration provided by Section 4(2) of the Securities Act of 1933. The initial purchasers then sold the notes to qualified institutional buyers pursuant to the exemption from registration provided by Rule 144A under the Securities Act.

In connection with the closing, we entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the initial purchasers, under which we agreed, for the benefit of the holders of the notes, to file with the Securities and Exchange Commission and maintain a shelf registration statement providing for the sale by the holders of the notes and Boston Properties, Inc.’s common stock, if any, issuable upon exchange of the notes. We will be required to pay liquidated damages in the form of specified additional interest to the holders of the notes if we fail to comply with these obligations; provided that we will not be required to pay liquidated damages with respect to any note after it has been exchanged for any of Boston Properties, Inc.’s common stock. On March 13, 2007, we filed with the SEC a registration statement covering the resale of the notes and shares of Boston Properties, Inc.’s common stock issuable upon exchange of the notes. The registration statement was declared effective by the SEC on April 20, 2007.

Off Balance Sheet Arrangements- Joint Venture Indebtedness

We have investments in seven unconsolidated joint ventures (including our investment in the Value-Added Fund which owns two properties) with our effective ownership interests ranging from 5% to 51%. All of these ventures have mortgage indebtedness. We exercise significant influence over, but do not control, these entities and therefore they are presently accounted for using the equity method of accounting. See also Note 4 to the Consolidated Financial Statements. At June 30, 2007, the debt related to these ventures was equal to approximately $599.6 million. The table below summarizes the outstanding debt of these joint venture properties at June 30, 2007:

Amount represents outstanding construction financing under a $60.0 million loan commitment (of which our share is $30.0 million) which bears interest at a fixed rate of 5.73% per annum and a $35.0 million loan commitment (of which our share is $17.5 million) which bears interest at a variable rate of LIBOR plus 1.25% per annum. The financing converts to a ten-year fixed rate loan in October 2007 at an interest rate of 5.73% per annum with a provision for an increase in the borrowing capacity by $35.0 million (of which our share would be $17.5 million). The conversion is subject to conditions which we expect to satisfy. As of

June 30, 2007, the interest rate on the variable rate portion of the debt was 6.57% per annum. The weighted-average rate as of June 30, 2007 is reflected in the table.

(2) The financing bears interest at a variable rate equal to LIBOR plus 2.25% per annum with a maturity of May 8, 2008.
(3) This property is owned by the Value-Added Fund.
(4) Amount represents outstanding construction financing under a $96.5 million loan commitment (of which our share is $23.1 million) at a variable rate equal to LIBOR plus 1.50% per annum with a maturity in March 2009. The mortgage debt requires interest only payments with a balloon payment due at maturity. On March 29, 2007, the entity executed an amendment to its construction loan agreement. The outstanding balance on the construction loan was approximately $53.6 million on the $96.5 million commitment. The amended agreement provides for a reduction in the loan commitment amount to $69.1 million. The reduction relates to the repayment of the retail portion of the outstanding balance totaling approximately $15.9 million and an additional reduction in the borrowing capacity of approximately $11.5 million with a corresponding release of collateral in conjunction with the retail entity obtaining new construction financing.
(5) In accordance with EITF 98-1, the principal amount and interest rates shown were adjusted to reflect the fair value of the note using an effective interest rate of 4.38% per annum. This note is non-interest bearing with a stated principal balance of $7.5 million (of which our share is approximately $1.8 million) and matures in January 2008. The weighted average rates exclude the impact of this loan. We have agreed, together with our third-party joint venture partners, to guarantee this seller financing on behalf of the land and infrastructure entity.
(6) Amount represents outstanding construction financing under a $66.0 million loan commitment collateralized by the retail entity of Wisconsin Place. Wisconsin Place is a mixed-use development project consisting of office, retail and residential properties located in Chevy Chase, Maryland. The construction financing bears interest at a variable rate equal to LIBOR plus 1.375% per annum and matures on March 29, 2010 with two one-year extension options.

State and Local Tax Matters

Because Boston Properties, Inc. is organized and qualify as a REIT, it is generally not subject to federal income taxes, but subject to certain state and local taxes. In the normal course of business, certain entities through which we own real estate either have undergone, or are currently undergoing, tax audits or other inquiries. Although we believe that we have substantial arguments in favor of our positions in the ongoing audits, in some instances there is no controlling precedent or interpretive guidance on the specific point at issue. Collectively, tax deficiency notices received to date from the jurisdictions conducting the ongoing audits have not been material. However, there can be no assurance that future audits will not occur with increased frequency or that the ultimate result of such audits will not have a material adverse effect on our results of operations.

Insurance

We carry insurance coverage on our properties of types and in amounts and with deductibles that we believe are in line with coverage customarily obtained by owners of similar properties. In response to the uncertainty in the insurance market following the terrorist attacks of September 11, 2001, the Federal Terrorism Risk Insurance Act, or TRIA, was enacted in November 2002 to require regulated insurers to make available coverage for certified acts of terrorism (as defined by the statute) through December 31, 2004, which date was extended to December 31, 2005 by the United States Department of Treasury on June 18, 2004 and which date was further extended to December 31, 2007 by the Terrorism Risk Insurance Extension Act of 2005 (the “TRIA Extension Act”). TRIA expires on December 31, 2007, and we cannot currently anticipate whether it will be extended. Effective as of March 1, 2007, our property insurance program per occurrence limits were increased from $800 million to $900 million, including (i) coverage for “certified” acts of terrorism by TRIA of $900 million per occurrence and (ii) coverage for “non-certified” acts of terrorism by TRIA of $500 million per occurrence, and an additional $400 million of coverage for “non-certified” acts of terrorism by TRIA on a per occurrence and

annual aggregate basis. We also carry nuclear, biological, chemical and radiological terrorism insurance coverage (“NBCR Coverage”) for “certified” acts of terrorism as defined by TRIA, which is provided by IXP, LLC as a direct insurer. Effective as of March 1, 2007, we extended the NBCR Coverage to March 1, 2008, excluding our Value-Added Fund properties. Effective as of March 1, 2007, the per occurrence limit for NBCR Coverage was increased from $800 million to $900 million. Under TRIA, after the payment of the required deductible and coinsurance the NBCR Coverage is backstopped by the Federal Government if the aggregate industry insured losses resulting from a certified act of terrorism exceed a “program trigger.” Under the TRIA Extension Act (a) the program trigger is $100 million from January 1, 2007 through December 31, 2007 and (b) the coinsurance is 15% from January 1, 2007 through December 31, 2007. We may elect to terminate the NBCR Coverage if there is a change in our portfolio or for any other reason. In the event TRIA is not extended beyond December 31, 2007 (i) the NBCR coverage provided by IXP will terminate and (ii) we will have some gaps in our coverage for acts of terrorism that would have constituted both “certified” and “non-certified” acts of terrorism had TRIA not expired and we may obtain the right to replace a portion of such coverage. We intend to continue to monitor the scope, nature and cost of available terrorism insurance and maintain insurance in amounts and on terms that are commercially reasonable.

We also currently carry earthquake insurance on our properties located in areas known to be subject to earthquakes in an amount and subject to self-insurance that we believe are commercially reasonable. In addition, this insurance is subject to a deductible in the amount of 5% of the value of the affected property. Specifically, we currently carry earthquake insurance which covers our San Francisco region with a $120 million per occurrence limit and a $120 million annual aggregate limit, $20 million of which is provided by IXP, LLC, as a direct insurer. The amount of our earthquake insurance coverage may not be sufficient to cover losses from earthquakes. We may discontinue earthquake insurance on some or all of our properties in the future if the premiums exceed our estimation of the value of the coverage.

In January 2002, we formed a wholly-owned taxable REIT subsidiary, IXP, Inc., to act as a captive insurance company and be one of the elements of our overall insurance program. On September 27, 2006, IXP, Inc. was merged into IXP, LLC, a wholly owned subsidiary, and all insurance policies issued by IXP, Inc. were cancelled and reissued by IXP, LLC. The term “IXP” refers to IXP, Inc. for the period prior to September 27, 2006 and to IXP, LLC for the period on and subsequent to September 27, 2006. IXP acts as a direct insurer with respect to a portion of our earthquake insurance coverage for our Greater San Francisco properties and our NBCR Coverage for “certified acts of terrorism” under TRIA. Insofar as we own IXP, we are responsible for its liquidity and capital resources, and the accounts of IXP are part of our consolidated financial statements. In particular, if a loss occurs which is covered by our NBCR Coverage but is less than the applicable program trigger under TRIA, IXP would be responsible for the full amount of the loss without any backstop by the Federal Government. If we experience a loss and IXP is required to pay under our insurance policy, we would ultimately record the loss to the extent of IXP’s required payment. Therefore, insurance coverage provided by IXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance.

We continue to monitor the state of the insurance market in general, and the scope and costs of coverage for acts of terrorism in particular, but we cannot anticipate what coverage will be available on commercially reasonable terms in future policy years. There are other types of losses, such as from wars or the presence of mold at our properties, for which we cannot obtain insurance at all or at a reasonable cost. With respect to such losses and losses from acts of terrorism, earthquakes or other catastrophic events, if we experience a loss that is uninsured or that exceeds policy limits, we could lose the capital invested in the damaged properties, as well as the anticipated future revenues from those properties. Depending on the specific circumstances of each affected property, it is possible that we could be liable for mortgage indebtedness or other obligations related to the property. Any such loss could materially and adversely affect our business and financial condition and results of operations.

Funds from Operations

Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”), we calculate Funds from Operations, or “FFO,” by adjusting net income (loss) (computed in accordance with GAAP, including non-recurring items) for gains (or losses) from sales of properties, real estate related depreciation and amortization, and after adjustment for unconsolidated partnerships, joint ventures and preferred distributions. FFO is a non-GAAP financial measure. The use of FFO, combined with the required primary GAAP presentations, has been fundamentally beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. Management generally considers FFO to be a useful measure for reviewing our comparative operating and financial performance because, by excluding gains and losses related to sales of previously depreciated operating real estate assets and excluding real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO can help one compare the operating performance of a company’s real estate between periods or as compared to different companies. Our computation of FFO may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently.

In addition to presenting FFO in accordance with the NAREIT definition, we also disclose FFO, as adjusted, for the three months ended June 30, 2006 which excludes the effects of the losses from early extinguishments of debt associated with the sales of real estate. The adjustment to exclude losses from early extinguishments of debt results when the sale of real estate encumbered by debt requires us to pay the extinguishment costs prior to the debt’s stated maturity and to write-off unamortized loan costs at the date of the extinguishment. Such costs are excluded from the gains on sales of real estate reported in accordance with GAAP. However, we view the losses from early extinguishments of debt associated with the sales of real estate as an incremental cost of the sale transactions because we extinguished the debt in connection with the consummation of the sale transactions and we had no intent to extinguish the debt absent such transactions. We believe that this supplemental adjustment more appropriately reflects the results of our operations exclusive of the impact of our sale transactions.

Although our FFO, as adjusted, clearly differs from NAREIT’s definition of FFO, and may not be comparable to that of other REITs and real estate companies, we believe it provides a meaningful supplemental measure of our operating performance because we believe that, by excluding the effects of the losses from early extinguishments of debt associated with the sales of real estate, adjustments for non-qualifying derivative contracts and early lease surrender payments, management and investors are presented with an indicator of our operating performance that more closely achieves the objectives of the real estate industry in presenting FFO.

Neither FFO nor FFO, as adjusted, should be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance. Neither FFO nor FFO, as adjusted, represent cash generated from operating activities determined in accordance with GAAP and is not a measure of liquidity or an indicator of our ability to make cash distributions. We believe that to further understand our performance, FFO and FFO, as adjusted, should be compared with our reported net income and considered in addition to cash flows in accordance with GAAP, as presented in our Consolidated Financial Statements.

Contractual Obligations

We have various standing or renewable service contracts with vendors related to our property management. In addition, we have certain other utility contracts we enter into in the ordinary course of business which may extend beyond one year, which vary based on usage. These contracts include terms that provide for cancellation with insignificant or no cancellation penalties. Contract terms are generally one year or less.

On February 15, 2007, we sold the long-term leasehold interest in 5 Times Square in New York City and related credits, for approximately $1.28 billion in cash. In conjunction with the sale, we have agreed to provide to the buyer monthly revenue support from the closing date until December 31, 2008. The aggregate amount of the revenue support payments will be approximately $1.6 million and has been recorded as a purchase price adjustment and included in Other Liabilities within our Consolidated Balance Sheets. As of June 30, 2007, the revenue support obligation totaled approximately $0.4 million.

In connection with the sale of 280 Park Avenue, we entered into a master lease agreement with the buyer at closing. Under the master lease agreement, we guaranteed that the buyer will receive at least a minimum amount of base rent from approximately 74,340 square feet of space during the ten-year period following the expiration of the current leases for this space. The current leases for this space are scheduled to expire at various times between June 2006 and October 2007. The aggregate amount of base rent we have guaranteed over the entire period from 2006 to 2017 is approximately $67.3 million. Our guarantee obligations, which are in the form of base rent payments to the buyer, will be reduced by the amount of base rent payable, whether or not actually paid, under qualifying leases for this space that we obtain from prospective tenants. We will remain responsible for any free rent periods. The buyer will bear all customary leasing costs for this space, including tenant improvements and leasing commissions. During the six months ended June 30, 2007, we signed a new qualifying lease for approximately 22,000 net rentable square feet of our remaining 47,659 net rentable square foot master lease obligation. Our remaining master lease obligation as of June 30, 2007 is approximately $26.9 million which is reflected in the Consolidated Balance Sheet as other liabilities.

Under the purchase and sale agreement for 280 Park Avenue we have also agreed to provide to the buyer fixed monthly revenue support from the closing date until December 31, 2008. The aggregate amount of the revenue support payments will be approximately $22.5 million and has been recorded as a purchase price adjustment and included in Other Liabilities within our Consolidated Balance Sheets. As of June 30, 2007, the revenue support obligation totaled approximately $10.7 million.

Newly Issued Accounting Standards

In June 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109” (“FIN No. 48”). FIN No. 48 clarifies the accounting for uncertainty in income taxes recognized in a company’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or

expected to be taken in a tax return. FIN No. 48 also provides guidance on description, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN No. 48 was effective for fiscal years beginning after December 15, 2006. FIN No. 48, which we adopted effective January 1, 2007, did not have a material impact on our cash flows, results of operations, financial position or liquidity.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS No. 157”). SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles (GAAP), and expands disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements. SFAS No. 157 applies under other accounting pronouncements that require or permit fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. We do not expect the adoption of SFAS No. 157 to have a material impact on our cash flows, results of operations, financial position or liquidity.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115” (“SFAS No. 159”). SFAS No. 159 permits entities to choose, at specified election dates, to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. Unrealized gains and losses shall be reported on items for which the fair value option has been elected in earnings at each subsequent reporting date. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating and assessing the impact of this statement.

ITEM 3—Quantitative and Qualitative Disclosures about Market Risk

Approximately $5.5 billion of our borrowings bear interest at fixed rates, and therefore the fair value of these instruments is affected by changes in the market interest rates. As of June 30, 2007, the weighted average interest rate on our variable rate debt was LIBOR/Eurodollar plus 1.25% per annum. The following table presents our aggregate fixed rate debt obligations with corresponding weighted-average interest rates sorted by maturity date and our aggregate variable rate debt obligations sorted by maturity date.

During 2005, we entered into twelve forward-starting interest rate swap contracts to lock in the 10-year treasury rate and 10-year swap spread in contemplation of obtaining long-term fixed-rate financing to refinance existing debt that was scheduled to expire or was freely prepayable prior to February 2007. Based on swap

 

66


Table of Contents

spreads at each trade date, the swaps fixed the 10-year treasury rate for a financing in February 2007 at a weighted average rate of 4.34% per annum on notional amounts aggregating $500.0 million. The swaps were to go into effect in February 2007 and expire in February 2017. We believe that these swaps qualify as highly-effective cash flow hedges under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” as amended. On December 19, 2006, we entered into an interest rate lock agreement with a lender for a fixed interest rate of 5.57% per annum on a ten-year mortgage financing totaling $750.0 million to be collateralized by our 599 Lexington Avenue property in New York City. We closed on the mortgage financing on February 12, 2007. In conjunction with the interest rate lock agreement, we terminated the forward-starting interest rate swap contracts and received approximately $10.9 million, which amount will reduce our interest expense over the ten-year term of the financing, resulting in an effective interest rate of 5.38% per annum. We expect that within the next twelve months we will reclassify into earnings approximately $1.0 million of the amounts recorded within Accumulated Other Comprehensive Loss relating to the forward-starting interest rate swap contracts. We intend to consider entering into additional hedging arrangements to minimize our interest rate risk.

In July and August 2007, we entered into four interest rate contracts, known as “treasury locks,” which fix the 10-year treasury rate at a weighted average rate of 4.782% per annum on notional amounts of $200.0 million. The treasury locks fix the 10-year treasury rate for a long-term fixed-rate financing commencing in April 2008 and expiring in April 2018. We expect to settle the interest rate contracts in cash at the time we lock the rate on long-term fixed-rate financing. If the 10-year treasury rate is below the fixed strike rate at the time we settle each contract, we would be required to make a payment to the contract counter-parties; if the 10-year treasury rate is above the fixed strike rate at the time we cash settle each contract, we would receive a payment from the contract counter-parties. The amount that we either pay or receive will equal the present value of the basis point differential between the applicable fixed strike rate and the 10-year treasury rate at the time we settle each contract. These treasury locks are designated as highly-effective cash flow hedges under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” as amended.

At June 30, 2007, our outstanding variable rate debt based off LIBOR totaled approximately $71 million. At June 30, 2007, the average interest rate on variable rate debt was approximately 6.63%. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $0.2 million for the three months ended June 30, 2007.

At June 30, 2006, our outstanding variable rate debt based off LIBOR totaled approximately $732.1 million. At June 30, 2006, the average interest rate on variable rate debt was approximately 5.70%. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $1.8 million for the three months ended June 30, 2006.

These amounts were determined solely by considering the impact of hypothetical interest rates on our financial instruments. Due to the uncertainty of specific actions we may undertake to minimize possible effects of market interest rate increases, this analysis assumes no changes in our financial structure.

ITEM 4 —Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this report, the management of Boston Properties, Inc., with the participation of its Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer of Boston Properties, Inc. concluded that these disclosure controls and procedures were effective as of the end of the period covered by this report.

(b) Changes in Internal Control Over Financial Reporting. No change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) occurred during the second quarter of our fiscal year ending December 31, 2007 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1—Legal Proceedings.

We are subject to legal proceedings and claims that arise in the ordinary course of business. These matters are generally covered by insurance. Management believes that the final outcome of such matters will not have a material adverse effect on our financial position, results of operations or liquidity.

ITEM 1A—Risk Factors.

There were no material changes to the risk factors disclosed in Part I, “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2006, except to the extent previously updated or to the extent additional factual information disclosed elsewhere in this Quarterly Report on Form 10-Q relates to such risk factors (including, without limitation, the matters discussed under Part I, “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Update on Recent Regulatory Initiatives.”) In addition to the other information set forth in this report, you should carefully consider the risk factors discussed in Form 10-K, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

ITEM 2—Unregistered Sales of Equity Securities and Use of Proceeds.

(a) Each time Boston Properties, Inc. issues shares of stock (other than in exchange for common units when such common units are presented for redemption), it contributes the proceeds of such issuance to us in return for an equivalent number of partnership units with rights and preferences analogous to the shares issued. During the three months ended June 30, 2007, in connection with issuances of common stock by Boston Properties, Inc. pursuant to exercises of stock options, the settlement of deferred stock awards and the issuance of restricted common stock under the Boston Properties, Inc. 1997 Stock Option and Incentive Plan, we issued an aggregate of approximately 21,002 common units to Boston Properties, Inc. in exchange for approximately $546,411, the aggregate proceeds of such common stock issuances to Boston Properties, Inc. Such units were issued in reliance on an exemption from registration under Section 4(2) of the Securities Act of 1933, as amended.
