BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO THE CONSOLIDATED 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 March 31, 2010 owned an approximate 85.9% (84.2% at March 31, 2009) 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”). In addition, in February 2008, the Company issued LTIP Units in connection with the granting to employees of 2008 outperformance awards (also referred to as “2008 OPP Units”). Because the rights, preferences and privileges of 2008 OPP Units differ from other LTIP Units granted to employees as part of the annual compensation process, unless specifically noted otherwise, all references to LTIP Units exclude 2008 OPP 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 is obligated to 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 7).

At March 31, 2010, 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 or redeemed for cash at the election of the holder thereof or the Company in accordance with the terms and conditions set forth in the applicable amendment to the partnership agreement (See Note 7).

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

Properties

At March 31, 2010, the Company owned or had interests in a portfolio of 143 commercial real estate properties (the “Properties”) aggregating approximately 37.6 million net rentable square feet, including five properties under construction totaling approximately 2.0 million net rentable square feet. In addition, the Company has structured parking for approximately 38,017 vehicles containing approximately 12.8 million square feet. At March 31, 2010, the Properties consist of:

 

   

137 office properties, including 118 Class A office properties (including three properties under construction) and 19 Office/Technical properties;

 

   

one hotel;

Table of Contents

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

   

three retail properties; and

 

   

two residential properties (both of which are under construction).

The Company owns or controls undeveloped land parcels totaling approximately 510.1 acres. In addition, the Company has a noncontrolling interest in the Boston Properties Office Value-Added Fund, L.P. (the “Value-Added Fund”), which is a strategic partnership with two institutional investors through which the Company has pursued the acquisition of value-added investments in assets within its existing markets. The Company accounts for its investment in the Value-Added Fund using the equity method of accounting. The Company’s investments through the Value-Added Fund are not included in its portfolio information or any other portfolio level statistics. At March 31, 2010, the Value-Added Fund had investments in 26 buildings comprised of an office property in Chelmsford, Massachusetts and office complexes in San Carlos, California and Mountain View, California.

The Company considers Class A office properties to be centrally located buildings that are professionally managed and maintained, that attract high-quality tenants and command upper-tier rental rates, and that are modern structures or have been modernized to compete with newer buildings. The Company considers Office/Technical properties to be properties that support office, research and development, laboratory and other technical uses.

2. Basis of Presentation and Summary of Significant Accounting Policies

Boston Properties, Inc. does not have any other significant assets, liabilities or operations, other than its investment in the Company, nor does it have employees of its own. 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. All significant intercompany balances and transactions have been eliminated in consolidation. The Company accounts for all other unconsolidated joint ventures using the equity method of accounting. Accordingly, the Company’s share of the earnings of these joint ventures and companies is included in consolidated net income.

The accompanying interim financial statements are unaudited; however, the financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and in conjunction with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the disclosures required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting solely of normal recurring matters) necessary for a fair statement of the financial statements for these interim periods have been included. The results of operations for the interim periods are not necessarily indicative of the results to be obtained for other interim periods or for the full fiscal year. The year end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosure required by accounting principles generally accepted in the United States of America. These financial statements should be read in conjunction with the Company’s financial statements and notes thereto contained in the Company’s Annual Report in the Company’s Form 10-K for its fiscal year ended December 31, 2009.

For purposes of financial reporting disclosures, the Company calculates the fair value of mortgage notes payable, unsecured senior notes and unsecured exchangeable senior notes. The Company discounts the spread between the future contractual interest payments and hypothetical future interest payments on mortgage debt and unsecured notes based on a current market rate. In determining the current market rate, the Company adds its estimates of market spreads to the quoted yields on federal government treasury securities with similar maturity dates to its debt. Because the Company’s valuations of its financial instruments are based on these types of

estimates, the actual fair values of its financial instruments may differ materially if the Company’s estimates do not prove to be accurate. The following table presents the aggregate carrying value of the Company’s indebtedness and the Company’s corresponding estimate of fair value as of March 31, 2010 (in thousands):

3. Real Estate Activity During the Three Months Ended March 31, 2010

Development

On February 6, 2009, the Company announced that it was suspending construction on its 1,000,000 square foot office building at 250 West 55th Street in New York City. During the first quarter of 2009, the Company recognized costs aggregating approximately $27.8 million related to the suspension of development, which amount included a $20.0 million contractual amount due pursuant to a lease agreement. During December 2009, the Company completed the construction of foundations and steel/deck to grade to facilitate a restart of construction in the future and as a result ceased interest capitalization on the project. On January 19, 2010, the Company paid $12.8 million related to the termination of the lease agreement. As a result, the Company recognized approximately $7.2 million of income during the first quarter of 2010.

Dispositions

On April 14, 2008, the Company sold a parcel of land located in Washington, DC for approximately $33.7 million. The Company had previously entered into a development management agreement with the buyer to develop a Class A office property on the parcel totaling approximately 165,000 net rentable square feet. Due to the Company’s involvement in the construction of the project, the gain on sale was deferred and has been recognized over the project construction period generally based on the percentage of total project costs incurred to estimated total project costs. During the three months ended March 31, 2010, the Company completed construction of the project and recognized the remaining gain on sale totaling approximately $1.8 million. The Company has recognized a cumulative gain on sale of approximately $23.4 million.

On March 1, 2010, a joint venture in which the Company has a 60% interest refinanced at maturity its mortgage loan collateralized by 125 West 55th Street located in New York City. The mortgage loan totaling $200.0 million bore interest at a fixed rate of 5.75% per annum. The new mortgage loan totaling $207.0 million bears interest at a fixed rate of 6.09% per annum and matures on March 10, 2015. In connection with the new mortgage loan, the Company has guaranteed the joint venture’s obligation to fund an escrow related to certain lease rollover costs in lieu of an initial cash deposit for the full amount. The maximum funding obligation under the guarantee was $21.3 million. At closing, the joint venture funded a $10.0 million cash deposit into the escrow account and the remaining $11.3 million will be further reduced with scheduled monthly deposits into the escrow account from operating cash flows. The Company earns a fee from the joint venture for providing the guarantee and has an agreement with the outside partners to reimburse the joint venture for their share of any payments made under the guarantee. In addition, on February 25, 2010, the joint venture repaid outstanding mezzanine loans totaling $63.5 million utilizing available cash and cash contributions from the joint venture’s partners on a pro rata basis. The mezzanine loans bore interest at a weighted-average fixed rate of approximately 7.81% per annum and were scheduled to mature on March 1, 2010.

In addition, the Company entered into capped call transactions with affiliates of certain of the initial purchasers, which are intended to reduce the potential dilution upon future exchange of the notes. The capped call transactions are intended to increase the effective exchange price to the Company of the notes from $117.58 to approximately $137.17 per share (subject to adjustment), representing an overall effective premium of approximately 40% over the closing price on August 13, 2008 of $97.98 per share of Boston Properties, Inc.’s Common Stock. The net cost of the capped call transactions was approximately $44.4 million.

(3) In connection with the special distribution of $5.98 per share of Boston Properties, Inc.’s Common Stock declared on December 17, 2007, the exchange rate was adjusted from 6.6090 to 7.0430 shares per $1,000 principal amount of notes effective as of December 31, 2007, resulting in an exchange price of approximately $141.98 per share of Boston Properties, Inc.’s Common Stock.
(4) Holders may require the Company to repurchase for cash the notes on February 15, 2012, 2017, 2022, 2027 and 2032 and at any time prior to their maturity upon a fundamental change, in each case at a price equal to 100% of the principal amount of the notes being repurchased plus any accrued and unpaid interest up to, but excluding, the repurchase date.
(5) In connection with the special distribution of $5.98 per share of Boston Properties, Inc.’s Common Stock declared on December 17, 2007, the exchange rate was adjusted from 9.3900 to 10.0066 shares per $1,000 principal amount of notes effective as of December 31, 2007, resulting in an exchange price of approximately $99.93 per share of Boston Properties, Inc.’s Common Stock.
(6) Holders may require the Company to repurchase for cash the notes on May 18, 2013 and May 15 of 2016, 2021, 2026 and 2031 and at any time prior to their maturity upon a fundamental change, in each case at a price equal to 100% of the principal amount of the notes being repurchased plus any accrued and unpaid interest up to, but excluding, the repurchase date.

The Company has separately accounted for the liability and equity components of its $862.5 million of 2.875% exchangeable senior notes due 2037, $450.0 million of 3.75% exchangeable senior notes due 2036 and $747.5 million of 3.625% exchangeable senior notes due 2014 by allocating the initial proceeds from the sale between a liability component and an equity component in a manner that reflects interest expense at the interest rate of similar nonconvertible debt that could have been issued by the Company at such time. The Company measured the fair value of the debt components of the 2.875%, 3.75% and 3.625% exchangeable senior notes for the periods presented based on effective interest rates of 5.630%, 5.958% and 6.555%, respectively. The aggregate carrying amount of the debt component was approximately $1.86 billion and $1.90 billion (net of the adjustment for the equity component allocation (net of accumulated amortization) of approximately $128.1 million and $140.4 million) at March 31, 2010 and December 31, 2009, respectively. As a result, the Company attributed an aggregate of approximately $230.3 million of the proceeds to the equity component of the notes, which represents the excess proceeds received over the fair value of the notes at the date of issuance. The Company also reclassified approximately $1.0 million of deferred financing costs to Partners’ Capital, which represented the costs attributable to the equity components of the notes. The equity component of the notes has been reflected within Partners’ Capital in the Consolidated Balance Sheets. The carrying amount of the equity component was approximately $229.3 million at March 31, 2010 and December 31, 2009. The resulting debt discount will be amortized over the period during which the debt is expected to be outstanding (i.e., through the first optional redemption dates or, in the case of the 2014 notes, the maturity date) as additional non-cash interest expense. The additional non-cash interest expense attributable to each debt security will increase in subsequent reporting periods through the first optional redemption date (or, in the case of the 2014 notes, the maturity date) as the debt accretes to its par value over the same period. The aggregate contractual interest expense was approximately $18.5 million and $18.5 million for the three months ended March 31, 2010 and 2009, respectively. As a result of accounting for the exchangeable senior notes in a manner that reflects the Company’s nonconvertible debt borrowing rate, the Company reported additional non-cash interest expense of approximately $10.1 million and $9.4 million for the three months ended March 31, 2010 and 2009, respectively.

During the first quarter of 2010, the Company repurchased approximately $53.6 million aggregate principal amount of its 2.875% exchangeable senior notes due 2037 for approximately $53.0 million. The repurchased notes had an aggregate carrying value of approximately $50.8 million, resulting in the recognition of a loss on extinguishment of approximately $2.2 million (See Note 12).

6. Commitments and Contingencies

General

In the normal course of business, the Company guarantees its performance of services or indemnifies third parties against its negligence.

The Company has letter of credit and performance obligations of approximately $12.5 million related to lender and development requirements.

Certain of the Company’s joint venture agreements include provisions whereby, at certain specified times, each partner has the right to initiate a purchase or sale of its interest in the joint ventures. Under these provisions, the Company is not compelled to purchase the interest of its outside joint venture partners.

In connection with the Company’s assumption of the General Motors Building’s secured loan by the Company’s unconsolidated joint venture, 767 Venture, LLC, the Company guaranteed the unconsolidated joint venture’s obligation to fund various escrows, including tenant improvements, taxes and insurance in lieu of cash deposits. As of March 31, 2010, the maximum funding obligation under the guarantee was approximately $16.3 million. In connection with the Company’s refinancing of the 125 West 55th Street property’s secured loan by the Company’s unconsolidated joint venture, 125 West 55th Street Venture LLC, the Company has guaranteed the unconsolidated joint venture’s obligation to fund an escrow related to certain lease rollover costs in lieu of an initial cash deposit for the full amount. The maximum funding obligation under the guarantee was $21.3 million. At closing, the joint venture funded a $10.0 million cash deposit into the escrow account and the remaining $11.3 million will be further reduced with scheduled monthly deposits into the escrow account from operating cash flows. As of March 31, 2010, the maximum funding obligation under the guarantee was $11.3 million. From time to time, the Company (or the applicable joint venture) has also agreed to guarantee portions of the principal, interest or other amounts in connection with other unconsolidated joint venture borrowings. In addition to the financial guarantees referenced above, the Company has agreed to customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) on certain of its unconsolidated joint venture loans.

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 (as amended, “TRIA”) was enacted in November 2002 to require regulated insurers to make available coverage for “certified” acts of terrorism (as defined by the statute). The expiration date of TRIA was extended to December 31, 2014 by the Terrorism Risk Insurance Program Reauthorization Act of 2007 (“TRIPRA”). Currently, the Company’s property insurance program per occurrence limits are $1.0 billion for its portfolio insurance program, including coverage for acts of terrorism certified under TRIA. The Company currently insures certain properties, including the General Motors Building located at 767 Fifth Avenue in New York, New York (“767 Fifth Avenue”), in separate stand alone insurance programs. The property insurance program per occurrence limits for 767 Fifth Avenue are $1.625 billion, including coverage for acts of terrorism certified under TRIA, with $1.375 billion of coverage for losses in excess of $250 million being provided by NYXP, LLC, as a direct insurer. The Company also currently carries nuclear, biological, chemical and radiological terrorism insurance coverage (“NBCR Coverage”) for acts of terrorism certified under TRIA, which is provided by IXP, LLC as a direct insurer, for the properties in our portfolio, including 767 Fifth Avenue, but excluding the properties owned by the Company’s Value-Added Fund and certain other properties owned in joint ventures with third parties or which we manage. The per occurrence limit for NBCR Coverage is $1.0 billion. Under TRIA, after the payment of the required deductible and coinsurance, the NBCR Coverage is backstopped

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

by the Federal Government if the aggregate industry insured losses resulting from a certified act of terrorism exceed a “program trigger.” The program trigger is $100 million and the coinsurance is 15%. Under TRIPRA, if the Federal Government pays out for a loss under TRIA, it is mandatory that the Federal Government recoup the full amount of the loss from insurers offering TRIA coverage after the payment of the loss pursuant to a formula in TRIPRA. The Company may elect to terminate the NBCR Coverage if the Federal Government seeks recoupment for losses paid under TRIA, if there is a change in its portfolio or for any other reason. 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. In addition, the amount of earthquake coverage could impact the Company’s ability to finance properties subject to earthquake risk. 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.

IXP, LLC (“IXP”), a captive insurance company which is a wholly-owned subsidiary of the Company, 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 acts of terrorism certified under TRIA. NYXP, LLC (“NYXP”), a captive insurance company which is a wholly-owned subsidiary of the Company, acts as a direct insurer with respect to a portion of the Company’s coverage for acts of terrorism certified under TRIA for 767 Fifth Avenue. Currently, NYXP only insures losses which exceed the program trigger under TRIA and NYXP reinsures with a third-party insurance company any coinsurance payable under TRIA. Insofar as the Company owns IXP and NYXP, it is responsible for their liquidity and capital resources, and the accounts of IXP and NYXP 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. IXP and NYXP would also be responsible for any recoupment charges by the Federal Government in the event losses are paid out and their insurance policies are maintained after the payout by the Federal Government. If the Company experiences a loss and IXP or NYXP are required to pay under their insurance policies, the Company would ultimately record the loss to the extent of the required payment. Therefore, insurance coverage provided by IXP and NYXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance.

The mortgages on the Company’s properties typically contain requirements concerning the financial ratings of the insurers who provide policies covering the property. The Company provides the lenders on a regular basis with the identity of the insurance companies in the Company’s insurance programs. The ratings of some of the Company’s insurers are below the rating requirements in some of the Company’s loan agreements and the lenders for these loans could attempt to claim an event of default has occurred under the loan. The Company believes it could obtain insurance with insurers which satisfy the rating requirements. Additionally, in the future, the Company’s ability to obtain debt financing secured by individual properties, or the terms of such financing, may be adversely affected if lenders generally insist on ratings for insurers which are difficult to obtain or which result in a commercially unreasonable premium. There can be no assurance that a deficiency in the financial ratings of one or more of the Company’s insurers will not have a material adverse effect on the Company.

 

14


Table of Contents

BOSTON PROPERTIES LIMITED PARTNERSHIP

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

The Company continues to monitor the state of the insurance market in general, and the scope and costs of coverage for acts of terrorism and California earthquake risk 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.

7. Noncontrolling Interests

Noncontrolling interests relate to the interests in the Company not owned by Boston Properties, Inc. and interests in property partnerships not wholly-owned by the Company. As of March 31, 2010, the noncontrolling interests consisted of 19,806,088 OP Units, 1,640,273 LTIP Units, 1,080,938 2008 OPP Units and 1,113,044 Series Two Preferred Units (or 1,460,688 OP Units on an as converted basis) held by parties other than Boston Properties, Inc.

Noncontrolling Interest—Redeemable Preferred Units

The Preferred Units at March 31, 2010 consisted solely of 1,113,044 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) a rate ranging from 5.00% to 7.00% per annum 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 on the Series Two Preferred Units are payable quarterly and, unless the greater rate described in the next sentence applies, accrue at 7.0% until May 12, 2009 and 6.0% thereafter. If distributions on the number of OP Units into which the Series Two Preferred Units are convertible are greater than distributions calculated using the rates described in the preceding sentence for the applicable quarterly period, then the greater distributions are payable instead. The holders of Series Two Preferred Units have the right to require the Company to redeem their units for cash at the redemption price of $50.00 per unit on May 12, 2011, May 14, 2012, May 14, 2013 and May 12, 2014. The maximum number of units that may be required to be redeemed from all holders on each of these dates is 1,007,662, which is one-sixth of the number of Series Two Preferred Units that were originally issued. The holders also had the right to have their Series Two Preferred Units redeemed for cash on May 12, 2009 and May 12, 2010, although no holder exercised such right. The Company also has the right, under certain conditions and at certain times, to redeem Series Two Preferred Units for cash and to convert into OP Units any Series Two Preferred Units that are not redeemed when they are eligible for redemption.

On February 16, 2010, the Company paid a distribution on its outstanding Series Two Preferred Units of $0.75616 per unit.

Due to the redemption option and the conversion option existing outside the control of the Company, the Preferred Units are not included in Partners’ Capital and are reflected in the Consolidated Balance Sheets at an amount equivalent to the value of such units had such units been redeemed at March 31, 2010. The value of the Series Two Preferred Units had all of such units been converted and then redeemed at March 31, 2010 was approximately $110.2 million based on the closing price of Boston Properties, Inc.’s common stock of $75.44 per share on that date.

During the three months ended March 31, 2010, 33,642 OP Units were presented by the holders for redemption (including 18,735 OP Units issued upon conversion of LTIP Units) and were redeemed by Boston Properties, Inc. in exchange for an equal number of shares of Common Stock.

At March 31, 2010, the Company had outstanding 1,080,938 2008 OPP Units. Prior to the measurement date on February 5, 2011, 2008 OPP Units will be entitled to receive per unit distributions equal to one-tenth (10%) of the regular quarterly distributions payable on an OP Unit, but will not be entitled to receive any special distributions. After the measurement date, the number of 2008 OPP Units, both vested and unvested, which 2008 OPP award recipients have earned, if any, based on the establishment of an outperformance pool, will be entitled to receive distributions in an amount per unit equal to distributions, both regular and special, payable on an OP Unit.

On January 29, 2010, the Company paid a distribution on the OP Units and LTIP Units in the amount of $0.50 per unit and a distribution on the 2008 OPP Units in the amount of $0.05 per unit to holders of record as of the close of business on December 31, 2009. On March 18, 2010, Boston Properties, Inc., as general partner of the Company, declared a distribution on the OP Units and LTIP Units in the amount of $0.50 per unit and a distribution on the 2008 OPP Units in the amount of $0.05 per unit, in each case payable on April 30, 2010 to holders of record as of the close of business on March 31, 2010.

Pursuant to the Company’s Partnership Agreement, certain limited partners in the Company have the right to redeem all or any portion of their interest for cash from the Company. However, Boston Properties, Inc. may elect to acquire the limited partner’s interest by issuing its Common Stock in exchange for the interest. The amount of cash to be paid to the limited partner if the redemption right is exercised and the cash option is elected is based on the trading price of Boston Properties, Inc.’s common stock at that time. Due to the redemption option existing outside the control of the Company, such limited partners’ units are not included in Partners’ Capital. The value of the OP Units not owned by Boston Properties, Inc. (including LTIP Units assuming that all conditions have been met for the conversion thereof) had all of such units been redeemed at March 31, 2010 was approximately $1.62 billion based on the closing price of Boston Properties, Inc.’s common stock of $75.44 per share.

Noncontrolling Interest—Property Partnerships

The noncontrolling 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, totaling approximately $6.0 million at March 31, 2010, are included in Noncontrolling Interests—Property Partnerships on the accompanying Consolidated Balance Sheets.

8. Partners’ Capital

As of March 31, 2010, Boston Properties, Inc. owned 1,604,504 general partnership units and 137,399,491 limited partnership units.

During the three months ended March 31, 2010, the Company issued 27,183 OP Units to Boston Properties, Inc. in connection with the exercise by employees of options to purchase Common Stock of Boston Properties, Inc.

During the three months ended March 31, 2010, Boston Properties, Inc. acquired 33,642 OP Units in connection with the redemption of an equal number of redeemable OP Units from third parties.

On January 29, 2010, the Company paid a distribution in the amount of $0.50 per OP Unit to unitholders of record as of the close of business on December 31, 2009. On March 18, 2010, Boston Properties, Inc. as general partner of the Company declared a distribution in the amount of $0.50 per OP Unit payable on April 30, 2010 to unitholders of record as of the close of business on March 31, 2010.

9. Earnings Per Common Unit

The following table provides a reconciliation of both the net income attributable to Boston Properties Limited Partnership and the number of common units used in the computation of basic earnings per common unit, which is calculated by dividing net income attributable to Boston Properties Limited Partnership by the weighted-average number of common units outstanding during the period. The terms of the Series Two Preferred Units enable the holders to obtain OP Units of the Company. As a result, the Series Two Preferred Units 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. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per common unit pursuant to the two-class method. As a result, unvested restricted common stock of Boston Properties, Inc. and the Company’s LTIP Units and 2008 OPP Units 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. Because the 2008 OPP Units require Boston Properties, Inc. to outperform absolute and relative return thresholds, unless such thresholds have been met by the end of the applicable reporting period, the Company excludes the 2008 OPP Units from the diluted earnings per common unit calculation. For the three months ended

March 31, 2010 and 2009, the absolute and relative return thresholds for the 2008 OPP Units were not met and as a result the 2008 OPP Units have been excluded from the diluted earnings per common unit calculation. Other potentially dilutive common units and the related impact on earnings are considered when calculating diluted earnings per common unit. Included in the number of units (the denominator) below are approximately 20,541,000 and 20,294,000 redeemable common units for the three months ended March 31, 2010 and 2009, respectively.

10. Stock Option and Incentive Plan

During the three months ended March 31, 2010, Boston Properties, Inc. issued 66,461 shares of restricted common stock and the Company issued 249,342 LTIP Units to employees and directors under the 1997 Stock Option and Incentive Plan (the “1997 Plan”). Employees and directors paid $0.01 per share of restricted common stock and $0.25 per LTIP Unit. The shares of restricted stock were valued at approximately $4.3 million ($64.87 per share). The LTIP Units were valued at approximately $15.1 million ($60.37 per unit fair value weighted-average) using a Monte Carlo simulation method model. 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 5.7 years, a risk-free interest rate of 2.60% and an expected price volatility of 36.0%. 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 noncontrolling interests in the Consolidated Balance Sheets. The restricted stock and 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 closing 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 in the Consolidated Balance Sheets. Stock-based compensation expense associated with restricted stock, LTIP Units and 2008 OPP Units was approximately $13.8 million and $6.8 million for the three months ended March 31, 2010 and 2009, respectively. For the three months ended March 31, 2010, stock-based compensation expense includes an aggregate of approximately $5.8 million of remaining previously unvested stock-based compensation granted between 2006 and 2009 to Edward H. Linde, Boston Properties, Inc.’s former Chief Executive Officer, which expense was accelerated as a result of his passing on January 10, 2010. At March 31, 2010, there was $42.6 million of unrecognized compensation expense related to unvested restricted stock and LTIP Units and $7.1 million of unrecognized compensation expense related to unvested 2008 OPP Units that is expected to be recognized over a weighted-average period of approximately 2.8 years. If upon the conclusion of the three-year measurement period in February 2011, the 2008 OPP Awards are not earned, and therefore the program is terminated, the Company will accelerate the then remaining unrecognized compensation expense totaling approximately $4.3 million during the first quarter of 2011.

11. 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, DC, Midtown Manhattan, Greater San Francisco and New Jersey. Segments by property type include: Class A Office, Office/Technical and Hotels.

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, loss (gain) from suspension of development, losses (gains) from investments in securities, losses from early extinguishments of debt, income from unconsolidated joint ventures, gains on sales of real estate and noncontrolling interests are not included in Net Operating Income as 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.

12. Subsequent Events

From April 1, 2010 through May 6, 2010, the Company repurchased approximately $111.8 million aggregate principal amount of its 2.875% exchangeable senior notes due 2037 for approximately $111.7 million.

On April 1, 2010, the Company acquired a 30% interest in a joint venture entity that owns 500 North Capitol Street, NW located in Washington, DC. 500 North Capitol Street is an approximately 180,000 net rentable square foot office property which is fully-leased to a single tenant through March 2011. On April 1, 2010, the joint venture entity refinanced at maturity the mortgage loan collateralized by the property totaling approximately $26.8 million. The new mortgage loan totaling $22.0 million bears interest at a variable rate equal to the greater of (1) the prime rate, as defined in the loan agreement, or (2) 5.75% per annum. The loan currently bears interest at 5.75% per annum and matures on March 31, 2013. The Company’s investment in the joint venture totaling approximately $1.9 million was financed with cash contributions to the venture totaling approximately $1.4 million and the issuance to the seller of 5,906 common units of limited partnership interest in the Company.

On April 9, 2010, a joint venture in which the Company has a 60% interest refinanced its mortgage loan collateralized by Two Grand Central Tower located in New York City. The previous mortgage loan totaling $190.0 million bore interest at a fixed rate of 5.10% per annum and was scheduled to mature on July 11, 2010. The new mortgage loan totaling $180.0 million bears interest at a fixed rate of 6.00% per annum and matures on April 10, 2015. In connection with the refinancing, the joint venture repaid $10.0 million of the previous mortgage loan utilizing cash contributions from the joint venture’s partners on a pro rata basis.

On April 16, 2010, a joint venture in which the Company has a 51% interest refinanced its mortgage loan collateralized by Metropolitan Square located in Washington, DC. The previous mortgage loan totaling

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

approximately $123.6 million bore interest at a fixed rate of 8.23% per annum and was scheduled to mature on May 1, 2010. The new mortgage loan totaling $175.0 million bears interest at a fixed rate of 5.75% per annum and matures on May 5, 2020.

On April 19, 2010, the Company completed a public offering of $700.0 million in aggregate principal amount of its 5.625% senior notes due 2020. The notes were priced at 99.891% of the principal amount to yield 5.638% to maturity. The aggregate net proceeds to the Company, after deducting underwriter discounts and offering expenses, were approximately $693.5 million. The notes mature on November 15, 2020, unless earlier redeemed. On April 7, 2010, in connection with the offering, the Company entered into two treasury lock agreements to fix the 10-year treasury rate at 3.873% per annum on notional amounts aggregating $350.0 million. The Company subsequently cash-settled the treasury lock agreements and received approximately $0.4 million, which amount will be recognized as a reduction to the Company’s interest expense over the ten-year term of the 5.625% senior notes due 2020.

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 collectively 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:

 

   

the continuing impact of the recent, severe economic recession (including the related high unemployment and constrained credit), which is having and may continue to have a negative effect on the following, among other things:

 

   

the fundamentals of our business, including overall market occupancy and rental rates;

 

   

the financial condition of our tenants, many of which are financial, legal and other professional firms, our lenders, counterparties to our derivative financial instruments and institutions that hold our cash balances and short-term investments, which may expose us to increased risks of default by these parties;

 

   

our ability to obtain debt financing on attractive terms or at all, which may adversely impact our ability to pursue acquisition and development opportunities and refinance existing debt and our future interest expense; and

 

   

the value of our real estate assets, which may limit our ability to dispose of assets at attractive prices or obtain or maintain debt financing secured by our properties or on an unsecured basis.

 

   

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;

 

   

the ability of our joint venture partners to satisfy their obligations;

 

   

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 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;

 

   

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

 

   

potential liability for uninsured losses and environmental contamination;

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. 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, DC, 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 and other landlord concessions, current and anticipated operating costs and real estate taxes, our current and anticipated vacancy, current and anticipated future demand for office space and general economic factors. From time to time, we also generate cash through the sale of assets.

Our core strategy has always been to operate in supply constrained markets with high barriers to entry and to focus on executing long-term leases with financially strong tenants. Historically, this combination has tended to

reduce our exposure in down cycles and we believe this is proving to be true once again. While the high rate of unemployment continues to negatively impact the fundamentals of our business, including overall market occupancy and rental rates, we are seeing signs of gradual improvement. Even with significant available space in all of the markets in which we operate, leasing velocity in our markets and our assets continues to improve. We believe that rental rates have stabilized and therefore tenants are less inclined to delay their leasing decisions. This manifested itself in the first quarter of 2010 as we completed more than 1.8 million square feet of leasing in 71 transactions. However, we continue to believe that general office market conditions are dependent on the impact of a recovery in the labor markets, and we are therefore not predicting strong rental rate growth or markedly fewer landlord concessions in the near-term. Leases representing approximately 6.4% and 8.5% of the space at our office properties expire during the remainder of 2010 and the full year of 2011, respectively. As these leases expire, the rental rates we are likely to achieve on any new leases are expected to be less than the rates currently being paid, thereby generally resulting in less revenue from the same space. For example, we estimate that the average rent currently paid by our office tenants for leases that expire during the remainder of 2010 is approximately 9% greater than current market rates for comparable space, and we estimate that the difference for our office leases that expire in 2011 is approximately 14%. Because the individual labor and industry markets may recover at different paces, we may see varying degrees of strength or softness in our core markets. We expect tenants in our markets to continue to take advantage of the ability to upgrade to high-quality space like ours and expect our occupancy to remain relatively stable during 2010.

Given the favorable low interest rate environment and the opportunity to further enhance our capital position we have been active in the capital markets. Since January 1, 2010, three of our unconsolidated joint ventures have refinanced approximately $562 million in three secured financings and in April we completed a public offering of $700 million aggregate principal amount of 5.625% senior notes due in 2020 that raised aggregate net proceeds of approximately $694 million. As of May 3, 2010, we have available cash of approximately $1.7 billion and borrowing capacity on our Unsecured Line of Credit of approximately $1.0 billion, which we believe is sufficient to meet all of our existing development funding obligations, repay near- term financings and provide significant capital for future investments. We believe the quality of our assets and our strong balance sheet are attractive to lenders’ and equity investors’ current investment selectivity and should enable us to continue to access multiple sources of capital. In addition, we believe deteriorated market fundamentals, overleveraged real estate assets and existing property owners with insufficient capital resources will eventually provide opportunities for well capitalized companies and seasoned operators, such as us, to acquire high-quality assets at attractive prices. Opportunities to acquire properties may come through outright property acquisitions, joint venture arrangements or through the purchase of first mortgage, mezzanine or other debt. In the last few months potential buyers have become more aggressive about expectations for a recovery and the volume of transactional activity has improved slightly as sellers are starting to test the markets and we believe participants in over leveraged real estate are beginning to push for resolution. While our management team is actively seeking opportunities, we will maintain our disciplined investment strategy, which focuses on high-quality assets in supply-constrained markets, emphasizing long-term value creation.

We believe the successful lease-up and completion of our development pipeline will enhance our long-term return on equity and earnings growth as these developments are placed in-service in 2010, 2011 and 2012. However, we do not anticipate undertaking new development projects in the foreseeable future without significant pre-leasing commitments from creditworthy tenants.

Transactions during the three months ended March 31, 2010 included the following:

 

   

On January 19, 2010, we paid $12.8 million related to the termination of a lease for our 250 West 55th Street development project in New York City. We announced in February 2009 that we were suspending construction of the 1,000,000 square foot office project. During the first quarter of 2009, we recognized costs aggregating approximately $27.8 million related to the suspension of development, which amount included a $20.0 million contractual amount due pursuant to the lease agreement. As a result, we recognized approximately $7.2 million of income during the first quarter of 2010.

On March 1, 2010, a joint venture in which we have a 60% interest refinanced at maturity its mortgage loan collateralized by 125 West 55th Street located in New York City. The previous mortgage loan totaling $200.0 million bore interest at a fixed rate of 5.75% per annum. The new mortgage loan totaling $207.0 million bears interest at a fixed rate of 6.09% per annum and matures on March 10, 2015. In addition, on February 25, 2010, the joint venture repaid outstanding mezzanine loans totaling $63.5 million utilizing available cash and cash contributions from the joint venture’s partners on a pro rata basis. The mezzanine loans bore interest at a weighted-average fixed rate of approximately 7.81% per annum and were scheduled to mature on March 1, 2010.

 

   

During the first quarter of 2010, we repurchased approximately $53.6 million aggregate principal amount of our 2.875% exchangeable senior notes due 2037 for approximately $53.0 million. The repurchased notes had an aggregate carrying value of approximately $50.8 million, resulting in the recognition of a loss on extinguishment of approximately $2.2 million.

Transactions completed subsequent to March 31, 2010:

 

   

From April 1, 2010 through May 6, 2010, we repurchased approximately $111.8 million aggregate principal amount of our 2.875% exchangeable senior notes due 2037 for approximately $111.7 million. These repurchased notes had an aggregate carrying value of approximately $106.4 million, resulting in the recognition of a loss on extinguishment of approximately $5.3 million during the second quarter of 2010.

 

   

On April 1, 2010, we acquired a 30% interest in a joint venture entity that owns 500 North Capitol Street, NW located in Washington, DC. 500 North Capitol Street is an approximately 180,000 net rentable square foot office property which is fully-leased to a single tenant through March 2011. On April 1, 2010, the joint venture entity refinanced at maturity the mortgage loan collateralized by the property totaling approximately $26.8 million. The new mortgage loan totaling $22.0 million bears interest at a variable rate equal to the greater of (1) the prime rate, as defined in the loan agreement, or (2) 5.75% per annum. The loan currently bears interest at 5.75% per annum and matures on March 31, 2013. Our investment in the joint venture totaling approximately $1.9 million was financed with cash contributions to the venture totaling approximately $1.4 million and the issuance to the seller of 5,906 common units of limited partnership interest in BPLP. The joint venture currently expects that it will remove the property from service and redevelop the property following the expiration of the lease in March 2011.

 

   

On April 9, 2010, a joint venture in which we have a 60% interest refinanced its mortgage loan collateralized by Two Grand Central Tower located in New York City. The previous mortgage loan totaling $190.0 million bore interest at a fixed rate of 5.10% per annum and was scheduled to mature on July 11, 2010. The new mortgage loan totaling $180.0 million bears interest at a fixed rate of 6.00% per annum and matures on April 10, 2015. In connection with the refinancing, the joint venture repaid $10.0 million of the previous mortgage loan utilizing cash contributions from the joint venture’s partners on a pro rata basis.

 

   

On April 16, 2010, a joint venture in which we have a 51% interest refinanced its mortgage loan collateralized by Metropolitan Square located in Washington, DC. The previous mortgage loan totaling approximately $123.6 million bore interest at a fixed rate of 8.23% per annum and was scheduled to mature on May 1, 2010. The new mortgage loan totaling $175.0 million bears interest at a fixed rate of 5.75% per annum and matures on May 5, 2020.

 

   

On April 19, 2010, we completed a public offering of $700.0 million in aggregate principal amount of our 5.625% senior notes due 2020. The notes were priced at 99.891% of the principal amount to yield 5.638% to maturity. The aggregate net proceeds to us, after deducting underwriter discounts and offering expenses, was approximately $693.5 million. The notes mature on November 15, 2020, unless earlier redeemed. On April 7, 2010, in connection with the offering, we entered into two treasury lock

 

27

agreements to fix the 10-year treasury rate at 3.873% per annum on notional amounts aggregating $350.0 million. We subsequently cash-settled the treasury lock agreements and received approximately $0.4 million, which amount will be recognized as a reduction to our interest expense over the ten-year term of the 5.625% senior notes due 2020.

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, and allocate the purchase price to the acquired assets and assumed liabilities, including land at appraised value and buildings as if vacant. 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.

Management reviews its long-lived assets used in operations for impairment following the end of each quarter and 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 criteria are 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

 

28


Table of Contents

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” 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.

ASC 360 (formerly known as 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 Boston Properties, Inc.’s Board of Directors, 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, and the asset is written down to the lower of carrying value or fair market value.

Real estate is stated at depreciated cost. A variety of costs are incurred in the acquisition, development and leasing of properties. The cost of buildings and improvements includes the purchase price of property, legal fees and other acquisition costs. Effective January 1, 2009, we were required to expense costs associated with the acquisition of real property such as legal, due diligence and other closing related 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. 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 held available for occupancy and capitalization must cease, involves a degree of judgment. Our capitalization policy on development properties is guided by guidance in ASC 835-20 “Capitalization of Interest” and ASC 970 “Real Estate—General” (formerly known as 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, (2) occupied or held available for occupancy, and we capitalize only those costs associated with the portion under construction or (3) if activities necessary for the development of the property have been suspended.

Investments in Unconsolidated Joint Ventures

Except for ownership interests in VIEs for which we are the primary beneficiary, 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. Our judgment with respect to our level of influence or control of an entity and whether we are the primary beneficiary of a VIE involves the consideration of various factors including the form of our ownership interest, our representation in the entity’s governance, the size of our investment (including loans), estimates of future cash flows, our ability to participate in policy making decisions and the rights of the other investors to participate in the decision making process and to replace us as manager and/or liquidate the venture, if applicable. Our assessment of our influence or control over an entity affects the presentation of these investments in our Consolidated Financial Statements.

 

29


Table of Contents

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 VIEs, we consolidate those in which we are the primary beneficiary. Our investments in unconsolidated joint ventures are reviewed for impairment periodically and we record impairment charges when events or circumstances change indicating that a decline in the fair value below the carrying values have occurred and such decline is other-than-temporary. The ultimate realization of our investment in unconsolidated joint ventures is dependent on a number of factors, including the performance of each investment and market conditions. We will record an impairment charge if we determine that a decline in the value of an investment in an unconsolidated joint venture is other than temporary.

To the extent that we contribute assets to a joint venture, our investment in the joint venture is recorded at our cost basis in the assets that were contributed to the joint venture. To the extent that our cost basis is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related asset and included in our share of equity in net income of the joint venture. We will recognize gains on the contribution of real estate to joint ventures, relating solely to the outside partner’s interest, to the extent the economic substance of the transaction is a sale.

The combined summarized financial information of the unconsolidated joint ventures is disclosed in Note 4 to the Consolidated Financial Statements.

Revenue Recognition

Contractual rental revenue is reported on a straight-line basis over the terms of our respective leases. 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.

For the three months ended March 31, 2010, we recorded approximately $0.6 million of rental revenue representing the adjustments of rents from “above-” and “below-market” leases. For the three months ended March 31, 2010, the impact of the straight-line rent adjustment increased rental revenue by approximately $24.2 million. Those amounts exclude the adjustment of rents from “above-” and “below-market” leases and straight-line income from unconsolidated joint ventures, which are disclosed in Note 4 to the Consolidated Financial Statements.

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;

 

   

revenue;

 

   

cash flows;

 

30


Table of Contents
   

leverage; 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 consistently monitor 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 through 4. A rating of 1 represents the highest possible rating and no allowance is recorded. A rating of 4 represents the lowest credit rating, in which case we record 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);

 

   

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 collectability 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, including unconsolidated joint ventures, was approximately 7.0 years as of March 31, 2010. 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 consistent 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 during which the expenses are incurred. Tenant reimbursements are recognized and presented in accordance with guidance in ASC 605-45 “Principal Agent Considerations” (“ASC 605-45”) (formerly known as Emerging Issues Task Force, or EITF, Issue 99-19 “Reporting Revenue Gross as a Principal versus Net as an Agent,” or “Issue 99-19”). ASC 605-45 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.

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.

 

31


Table of Contents

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 as earned 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 included in ASC 360-20 “Real Estate Sales” (“ASC 360-20”) (formerly known as SFAS No. 66, “Accounting for Sales of Real Estate”). The specific timing of the sale is measured against various criteria in ASC 360-20 related to the terms of the transaction and any continuing involvement in the form of management or financial assistance associated with the properties. If the criteria for the full accrual method are not met, we defer some or all of the gain recognition and account for the continued operations of the property by applying the finance, leasing, profit sharing, deposit, 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. 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 hypothetical future interest payments on our mortgage debt and unsecured notes based on a current market rate. In determining the current market rate, we 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 actual fair value of our financial instruments may differ materially if our estimates do not prove to be accurate.

Derivative Instruments and Hedging Activities

Derivative instruments and hedging activities require management to make judgments on the nature of its derivatives and their effectiveness as hedges. These judgments determine if the changes in fair value of the derivative instruments are reported in the Consolidated Statements of Operations as a component of net income or as a component of comprehensive income and as a component of equity on the Consolidated Balance Sheets. While management believes its judgments are reasonable, a change in a derivative’s effectiveness as a hedge could materially affect expenses, net income and equity.

Results of Operations

The following discussion is based on our Consolidated Financial Statements for the three months ended March 31, 2010 and 2009.

At March 31, 2010 and March 31, 2009, we owned or had interests in a portfolio of 143 and 147 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

 

32


Table of Contents

Property Portfolio are necessarily meaningful. Therefore, the comparison of operating results for the three months ended March 31, 2010 and 2009 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 properties included in the Placed In-Service 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 or acquired 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 attributable to Boston Properties Limited Partnership, the most directly comparable GAAP financial measure, plus income attributable to noncontrolling interests, losses (gains) from investments in securities, losses from early extinguishments of debt, loss (gain) from suspension of development, depreciation and amortization, interest expense, general and administrative expense, less gains on sales of real estate, income from unconsolidated joint ventures, 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 attributable to Boston Properties Limited Partnership. NOI excludes certain components from net income attributable to Boston Properties Limited Partnership 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 attributable to Boston Properties Limited Partnership as presented in our Consolidated Financial Statements. NOI should not be considered as an alternative to net income attributable to Boston Properties Limited Partnership as an indication of our performance or to cash flows as a measure of liquidity or ability to make distributions. For a reconciliation of NOI to net income attributable to Boston Properties Limited Partnership, see Note 11 to the Consolidated Financial Statements.

Comparison of the three months ended March 31, 2010 to the three months ended March 31, 2009.

The table below shows selected operating information for the Same Property Portfolio and the Total Property Portfolio. The Same Property Portfolio consists of 134 properties totaling approximately 34.8 million net rentable square feet of space. The Same Property Portfolio includes properties acquired or placed in-service on or prior to January 1, 2009 and owned through March 31, 2010. The Total Property Portfolio includes the effects of the other properties either placed in-service, acquired or repositioned after January 1, 2009 or disposed of on or prior to March 31, 2010. There were no properties that were acquired, sold or repositioned after January 1, 2009.

Same Property Portfolio

Rental Revenue

Rental revenue from the Same Property Portfolio decreased approximately $8.5 million for the three months ended March 31, 2010 compared to 2009. Included in Same Property Portfolio rental revenue is an overall decrease in contractual rental revenue of approximately $7.8 million, recoveries from tenants of approximately $8.4 million and parking and other income of approximately $1.1 million. These decreases were offset by an approximately $8.8 million increase in straight-line rent. The decrease in contractual rental revenue and increase in straight-line revenue are primarily due to new leases at 399 Park Avenue in New York City and a major law firm lease (approximately 480,000 square feet) in Boston being in free rent periods. The free rent periods for the lease in New York City range from six to twelve months, while the law firm’s lease in Boston has twelve months of free rent.

Generally, under each of our leases, we are entitled to recover from the tenant increases in specific operating expenses associated with the leased property above the amount incurred for these operating expenses in the first year of the lease. The decrease in recoveries from tenants is primarily due to the terminations by tenants in New York City and a large lease expiration in Boston, which resulted in lesser tenant recoveries due to the fact that although the majority of the space was re-leased, the leases are in their first year during which, generally, no tenant recoveries are earned.

Real Estate Operating Expenses

Operating expenses from the Same Property Portfolio decreased approximately $0.8 million for the three months ended March 31, 2010 compared to 2009. Included in Same Property Portfolio operating expenses is an increase in real estate taxes of approximately $1.4 million, or 2.7%, and an increase in insurance of approximately $1.5 million. This was offset by overall decreases in utilities expense of approximately $1.0 million and other property-related expenses of approximately $2.7 million.

Depreciation and Amortization Expense

Depreciation and amortization expense for the Same Property Portfolio increased approximately $3.4 million for the three months ended March 31, 2010 compared to 2009. Approximately $1.6 million of the increase is due to accelerated depreciation related to our decision to reclassify three in-service properties to land held for future development. These three properties total approximately 131,000 square feet, are currently planned for redevelopment and are no longer held available for lease.

Placed In-Service Portfolio

In addition to the Same Property Portfolio, at March 31, 2010, we had four additional properties totaling approximately 838,000 square feet that were placed in-service between January 1, 2009 and March 31, 2010.

Depreciation and amortization expense for our Placed In-Service Portfolio increased by approximately $2.3 million for the three months ended March 31, 2010 compared to 2009.

Other Income and Expense Items

Termination Income

We recognized termination income totaling approximately $1.0 million for the three months ended March 31, 2010, which was related to four tenants across the Total Property Portfolio. This compared to $0.6 million of termination income for the three months ended March 31, 2009 related to five tenants. During the second quarter of 2010, we will be receiving approximately $1.2 million of termination income from a small retail tenant in New York City.

Hotel Net Operating Income

Net operating income for the Cambridge Center Marriott hotel property increased by approximately $45,000 for the three months ended March 31, 2010 as compared to 2009. We expect our hotel net operating income for fiscal 2010 to be between $6.0 million and $6.5 million.

The following reflects our occupancy and rate information for the Cambridge Center Marriott hotel for the three months ended March 31, 2010 and 2009.

Development and Management Services

Development and management services income increased approximately $0.6 million for the three months ended March 31, 2010 compared to 2009. Development fees increased by approximately $0.1 million for the three months ended March 31, 2010 compared to 2009 due primarily to an increase in tenant improvement fees of approximately $0.2 million offset by a decrease of approximately $0.1 million in development fees. The decrease in development fees is the result of the completion of our 20 F Street third-party development project and the completion and placing in-service of our Wisconsin Place joint venture development project. Management fees

 

36


Table of Contents

increased by approximately $0.5 million for the three months ended March 31, 2010 compared to 2009 due primarily to leasing fees earned at 125 West 55th Street. We expect third-party fee income for fiscal 2010 to be between $25 million and $30 million. The anticipated reduction compared to 2009 is due to the completion of some significant third-party development fees received from our joint venture development projects and our third party development services performed at 20 F Street.

Interest and Other Income

Interest and other income increased approximately $1.4 million for the three months ended March 31, 2010 compared to 2009 as a result of increased average cash balances partially offset by the net effect of lower overall interest rates. The average cash balances for the three months ended March 31, 2010 and March 31, 2009 were approximately $1.3 billion and $0.1 billion, respectively. The increase in the average cash balance was primarily due to (1) the aggregate net proceeds of approximately $841.9 million that Boston Properties, Inc. received, and contributed to us, from its public offering of 17,250,000 shares of Common Stock in June 2009 and (2) the aggregate net proceeds of approximately $693.7 million that we received from our issuance of $700 million aggregate principal amount of 5.875% unsecured notes due 2019 in October 2009. In addition, the average interest rate for the three months ended March 31, 2010 compared to March 31, 2009 decreased by approximately 0.55%.

Other Expenses

General and Administrative

General and administrative expenses increased approximately $9.4 million for the three months ended March 31, 2010 compared to 2009. The increase was due to an overall increase in payroll expense of approximately $8.6 million, of which approximately $5.4 million represents the accelerated expense of the remaining stock-based compensation granted between 2006 and 2009 to Edward H. Linde, our former Chief Executive Officer, as a result of his passing on January 10, 2010. The remaining approximately $3.2 million increase in payroll expenses is the result of the annual stock-based compensation awarded under our long term incentive program, an increase in the value of our deferred compensation plan, and an increase in the bonus accrual. The remaining increase of approximately $0.8 million relates to an overall increase in professional fees and other general and administrative expenses. We expect general and administrative expense for fiscal 2010 to be between $81 million and $83 million.

The following properties are included in the repayment of mortgages line item: Reservoir Place, Ten Cambridge Center and 1301 New York Avenue. The following properties are included in the new mortgages/properties placed in-service line item: Democracy Tower, Wisconsin Place Office and Reservoir Place.

At March 31, 2010, our variable rate debt consisted of our construction loans at South of Market, Democracy Tower, Wisconsin Place Office and Atlantic Wharf (formerly Russia Wharf), as well as our Unsecured Line of Credit and our secured financing at Reservoir Place. For a summary of our consolidated debt as of March 31, 2010 and March 31, 2009 refer to the heading “Liquidity and Capital Resources—Capitalization-Debt Financing” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

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 March 31, 2010 and 2009 were $2.5 million and $2.4 million, respectively. These costs are not included in the general and administrative expenses discussed above. Interest capitalized for the three months ended March 31, 2010 and 2009 was $8.1 million and $12.1 million, respectively. These costs are not included in the interest expense referenced above. The decrease in capitalized interest is primarily due to the suspension of development at 250 West 55th Street.

Loss (Gain) from Suspension of Development

On February 6, 2009, we announced that we were suspending construction on our 1,000,000 square foot office building at 250 West 55th Street in New York City. During the first quarter of 2009, the Company recognized costs aggregating approximately $27.8 million related to the suspension of development, which amount included a $20.0 million contractual amount due pursuant to a lease agreement. During December 2009, we completed the construction of foundations and steel/deck to grade to facilitate a restart of construction in the future and as a result ceased interest capitalization on the project. On January 19, 2010, we paid $12.8 million related to the termination of the lease agreement. As a result, we recognized approximately $7.2 million of income during the first quarter of 2010.

During the three months ended March 31, 2010, we completed all of our remaining work related to the suspension of development and recognized approximately $0.4 million of additional costs. In order to maintain this property, we anticipate future expenses for taxes, insurance and security will be approximately $2.0 million per fiscal year. These costs have been and similar future costs will be classified as real estate operating expenses and not as loss from suspension of development.

Losses from Early Extinguishments of Debt

During the first quarter of 2010, we repurchased approximately $53.6 million aggregate principal amount of our 2.875% exchangeable senior notes due 2037 for approximately $53.0 million. The repurchased notes had an aggregate carrying value of approximately $50.8 million, resulting in the recognition of a loss on extinguishment of approximately $2.2 million.

From April 1, 2010 through May 6, 2010, we repurchased approximately $111.8 million aggregate principal amount of the 2.875% exchangeable senior notes due 2037 for approximately $111.7 million. These repurchased notes had an aggregate carrying value of approximately $106.4 million, resulting in the recognition of a loss on extinguishment of approximately $5.3 million during the second quarter of 2010.

Losses (Gains) from Investments in Securities

acquisition. During the three months ended March 31, 2009, investment in securities is comprised of an investment in an unregistered money market fund and investments in an account associated with our deferred compensation plan. In December 2007, the unregistered money market fund suspended cash redemptions by investors; investors could elect in-kind redemptions of the underlying securities or maintain their investment in the fund and receive distributions as the underlying securities matured or were liquidated by the fund sponsor. As a result, we retained this investment for a longer term than originally intended, and the valuation of our investment was subject to changes in market conditions. Because interests in this fund were valued at less than their $1.00 par value, we recognized losses (gains) of approximately ($32,000) on our investment during the three months ended March 31, 2009. As of December 31, 2009, we no longer had investments in this unregistered money market fund.

The remainder of the losses (gains) from investments in securities for the three months ended March 31, 2010 and 2009 related to investments that we have made to reduce our market risk relating to a deferred compensation plan that we maintain for our officers. Under this deferred compensation plan, each officer who is eligible to participate is permitted to defer a portion of the officer’s current income on a pre-tax basis and receive a tax-deferred return on these deferrals based on the performance of specific investments selected by the officer. In order to reduce our market risk relating to this plan, we typically acquire, in a separate account that is not restricted as to its use, similar or identical investments as those selected by each officer. This enables us to generally match our liabilities to our officers under the deferred compensation plan with equivalent assets and thereby limit our market risk. The performance of these investments is recorded as loss (gain) from investments in securities. During the three months ended March 31, 2010 and 2009, respectively, we recognized losses (gains) of $(0.2) million and $0.6 million on these investments. By comparison, our general and administrative expense increased (decreased) by $0.3 million and $(0.4) million during the three months ended March 31, 2010 and 2009, respectively, as a result of increases and decreases in our liability under our deferred compensation plan that were associated with the performance of the specific investments selected by our officers participating in the plan.

Income from Unconsolidated Joint Ventures

For the three months ended March 31, 2010 compared to 2009, income from unconsolidated joint ventures increased by approximately $2.8 million. Income from our unconsolidated joint venture Same Property Portfolio increased approximately $3.2 million for the three months ended March 31, 2010 compared to 2009 and approximately $2.6 million of the increase was from the General Motors Building and due to lease extensions and lease termination income. In addition, we recognized a loss from our unconsolidated joint venture Placed In-Service Portfolio of approximately $0.4 million related to the Wisconsin Place infrastructure which includes a garage and retail space.

Gains on sales of real estate

On April 14, 2008, we sold a parcel of land located in Washington, DC for approximately $33.7 million. We had previously entered into a development management agreement with the buyer to develop a Class A office property on the parcel totaling approximately 165,000 net rentable square feet. Due to our involvement in the construction of the project, the gain on sale was deferred and has been recognized over the project construction period generally based on the percentage of total project costs incurred to estimated total project costs. As a result, we recognized a gain on sale during the three months ended March 31, 2009 of approximately $2.8 million. During the three months ended March 31, 2010, we completed construction of the project and recognized the remaining gain on sale totaling approximately $1.8 million. We have recognized a cumulative gain on sale of approximately $23.4 million.

Noncontrolling interests in property partnerships

Noncontrolling interests in property partnerships increased by approximately $0.3 million for the three months ended March 31, 2010 compared to 2009. Noncontrolling interests in property partnerships consist of the outside equity owners’ interests in the income from our 505 9th Street and our Wisconsin Place Office properties. The increase is primarily due to placing in-service Wisconsin Place Office during the second quarter of 2009.

Liquidity and Capital Resources

General

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

 

   

fund normal recurring expenses;

 

   

meet debt service and principal repayment obligations, including balloon payments on maturing debt;

 

   

fund capital expenditures, including major renovations, tenant improvements and leasing costs;

 

   

fund development costs;

 

   

fund possible property acquisitions; and

 

   

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

We expect to satisfy these needs using one or more of the following:

 

   

cash flow from operations;

 

   

distribution of cash flows from joint ventures;

 

   

cash and cash equivalent balances;

 

   

issuances of Boston Properties, Inc.’s equity securities and/or additional preferred or common units;

 

   

our Unsecured Line of Credit or other short-term bridge facilities;

 

   

construction loans;

 

   

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

 

   

sales of real estate.

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 seek to fund our development projects with construction loans, which may be guaranteed. However, the financing for each particular project ultimately depends on several factors, including, among others, the project’s size and duration and our access to cost effective capital at the given time.

Contractual rental revenue, recoveries from tenants, other income from operations, available cash balances and draws on our Unsecured Line of Credit are our principal sources of capital used to pay operating expenses, debt service, recurring capital expenditures and the minimum distribution required to enable Boston Properties, Inc. to maintain its REIT qualification. We seek to maximize 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. We believe our revenue, together with our cash balances and proceeds from financing activities, will continue to provide the necessary funds for our short-term liquidity needs.

Material adverse changes in one or more sources of capital 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 capital strategy is to maintain access to multiple sources of capital including secured debt, unsecured debt, and public and private equity such that turmoil in one or more of these sources does not eliminate our access to capital. Consistent with this strategy, (1) since January 1, 2010, three of our unconsolidated joint ventures have refinanced approximately $562 million in three secured financings and (2) in April 2010, we issued $700 million aggregate principal amount of 5.625% senior notes due 2020. These transactions bolstered our liquidity position and, with cash balances as of May 3, 2010 of approximately $1.7 billion and borrowing capacity on our Unsecured Credit facility of approximately $1.0 billion, we are well positioned to meet all of our current development funding obligations, repay near-term debt maturities and make new opportunistic investments.

We and our unconsolidated joint ventures also have an aggregate of approximately $290 million (of which our share is approximately $269 million) of construction loans maturing in 2010. Subject to satisfying certain conditions, we have the right to extend these facilities. Our Market Square North unconsolidated joint venture has approximately $81 million (of which our share is approximately $41 million) of secured debt maturing in December 2010, which we expect to refinance. In addition, we expect to repay at maturity in 2010 an aggregate of approximately $78 million of secured debt on three assets in our Carnegie Center portfolio and one building in Cambridge, MA.

Our Unsecured Line of Credit expires in August 2010 and contains a one-year extension at our option provided that we are not in default. We currently expect that we will exercise this option and extend the maturity date to August 2011. Our most significant capital commitments after 2010 are to fund our development program and repay or refinance expiring debt.

In addition to our Unsecured Line of Credit and property-specific debt, as of May 3, 2010 we also had approximately $4.8 billion of unsecured senior notes outstanding (including approximately $1.9 billion of exchangeable notes). All of this debt either matures or is subject to repurchase at the holders’ option between 2012 and 2020. We are focused on our near-term debt maturities and to date, we have repurchased approximately $165 million of our 2.875% exchangeable senior notes due 2037, which the holders may require us to repurchase in 2012, at slight discounts to par. In order to reduce future cash interest payments, as well as future amounts due at maturity or upon redemption, we may, from time to time, purchase unsecured senior notes and unsecured exchangeable senior notes for cash in open market purchases or privately negotiated transactions, or both. We will evaluate any such potential transactions in light of then-existing market conditions, taking into account the trading prices of the notes, our current liquidity and prospects for future access to capital.

Table of Contents

In total, our remaining capital requirements, net of anticipated and potential funding from existing construction loans, to complete our ongoing developments is approximately $246 million, through mid 2012. With available cash proceeds, access to our Unsecured Line of Credit and the anticipated cash flow generated by the operating portfolio, we believe we have sufficient capacity to fund our remaining capital requirements and pursue attractive investment opportunities.

Finally, in prior years, we have been an active seller of real estate assets and, although we will consider additional asset sales, we do not expect any material asset sales in the near future.

REIT Tax Distribution Considerations

Dividend

A REIT is subject to a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its annual taxable income. Boston Properties, Inc.’s policy is to distribute at least 100% of its taxable income to avoid paying federal tax. With a view toward increasing equity over time and preserving additional capital, Boston Properties, Inc., our general partner, reduced our quarterly distribution in the second quarter of 2009 to $0.50 per unit. Based on Boston Properties, Inc.’s current expectation for taxable income over the next few years, and absent any unanticipated circumstances, we expect that our quarterly distribution will be approximately $0.50 per unit for the next several quarters. There can be no assurance that the actual distributions declared by Boston Properties, Inc.’s Board of Directors will not differ materially.

Sales

To the extent that we sell assets and cannot efficiently use the proceeds in a tax deferred manner for either our development activities or attractive acquisitions, Boston Properties, Inc., our general partner, would, at the appropriate time, decide whether it is better to declare a special distribution, 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 cost and availability of capital from other sources, 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 Boston Properties, Inc. 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 approximately $1.2 billion and $0.1 billion at March 31, 2010 and 2009, respectively, representing an increase of approximately $1.1 billion. The following table sets forth decreases in cash flows:

Our principal source of cash flow is related to the operation of our office properties. The average term of our in-place tenant leases, including our unconsolidated joint ventures, is approximately 7.0 years with occupancy rates historically in the range of 92% to 95%. Our properties provide a relatively consistent stream of cash flow

that provides us with resources to pay operating expenses, debt service and fund quarterly distribution payment requirements. In addition, over the past several years, we have raised capital through the sale of some of our properties, secured and unsecured borrowings and equity offerings done by Boston Properties, Inc.

For the three months ended March 31, 2010, our total distributions exceeded our cash flows from operating activities by approximately $20.9 million primarily as a result of several large, long-term leases where the tenants are in free rent periods and the payment related to the termination of a lease agreement for our 250 West 55th Street development project in New York City, as well as other factors. The excess cash flows needed to fund the distributions was provided from available cash. We expect our cash flows from operations to exceed our distributions as the free rent periods expire; however, to the extent our distributions exceed our cash flows from operating activities in future quarters, we expect to fund the shortfall from available cash or financing activities, or both.

Cash is used in investing activities to fund acquisitions, development, net investments in unconsolidated joint ventures 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 used in investing activities for the three months ended March 31, 2010, consisted primarily of funding our development projects and our investment in the unconsolidated joint venture that owns 125 West 55th Street to repay the joint venture’s outstanding mezzanine loans, and is detailed below:

Cash used in financing activities for the three months ended March 31, 2010 totaled approximately $135.7 million. This consisted primarily of the payments of distributions to our unitholders and the repurchasing of a portion of our 2.875% exchangeable senior notes due 2037. Future debt payments are discussed below under the heading “Capitalization-Debt Financing.”

Capitalization

At March 31, 2010, our total consolidated debt was approximately $6.7 billion. The GAAP weighted-average annual interest rate on our consolidated indebtedness was 5.87% (with a coupon/stated rate of 5.22%) and the weighted-average maturity was approximately 4.4 years.

Consolidated debt to total consolidated market capitalization ratio, defined as total consolidated debt as a percentage of the 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 consolidated market capitalization was approximately $18.9 billion at March 31, 2010. Total consolidated market capitalization was calculated using the March 31, 2010 closing stock price of $75.44 per common share and the following: (1) 158,810,083 outstanding common units of limited partnership (including 139,003,995 common units held by Boston Properties, Inc.), (2) an aggregate of 1,460,688 common units issuable upon conversion of all outstanding Series Two Preferred Units of partnership interest, (3) an aggregate of 1,640,273 common units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units, and (4) our consolidated debt totaling approximately $6.7 billion. The calculation of total consolidated market capitalization does not include 1,080,938 2008 OPP Units because, unlike other LTIP Units, they are not earned until certain return thresholds are achieved. Our total consolidated debt, which excludes debt collateralized by our unconsolidated joint ventures, at March 31, 2010, represented approximately 35.34% of our total consolidated market capitalization. This percentage will fluctuate with changes in the market value 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 consolidated debt to total consolidated 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.

For a discussion of our unconsolidated joint venture indebtedness, see “Liquidity and Capital Resources—Capitalization—Off-Balance Sheet Arrangements—Joint Venture Indebtedness” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Debt Financing

As of March 31, 2010, we had approximately $6.7 billion of outstanding consolidated indebtedness, representing approximately 35.34% of our total consolidated market capitalization as calculated above consisting of (1) $2.173 billion (net of discount) in publicly traded unsecured senior notes (excluding exchangeable senior notes) having a weighted-average interest rate of 6.01% per annum and maturities in 2013, 2015 and 2019; (2) $421.8 million (net of adjustment for the equity component allocation) of exchangeable senior notes having a GAAP interest rate of 5.958% per annum (an effective rate of 3.787% per annum, excluding the effect of the adjustment for the equity component allocation), an initial optional redemption date in 2013 and maturity in 2036; (3) $769.8 million (net of discount and adjustment for the equity component allocation) of exchangeable senior notes having a GAAP interest rate of 5.630% per annum (an effective rate of 3.462% per annum, excluding the effect of the adjustment for the equity component allocation), an initial optional redemption date in 2012 and maturing in 2037; (4) $673.2 million (net of discount and the adjustment for the equity component allocation ) of exchangeable senior notes having a GAAP interest rate of 6.555% per annum (an effective rate of 4.037%, excluding the effect of the adjustment for the equity component allocation) and maturing in 2014; and (5) $2.6 billion of property-specific mortgage debt having a GAAP weighted-average interest rate of 5.65% per annum and weighted-average term of 4.4 years.

The variable rate debt shown above bears interest based on various spreads over the London Interbank Offered Rate or Eurodollar rates. As of March 31, 2010, the weighted-average interest rate on our variable rate debt was LIBOR/Eurodollar plus 1.50% per annum.

Unsecured Line of Credit

The lenders’ total commitment under our Unsecured Line of Credit is $1.0 billion. Our Unsecured Line of Credit bears interest at a variable interest rate equal to Eurodollar plus 0.475% per annum and matures on August 3, 2010, with a provision for a one-year extension at our option, subject to certain conditions. There can be no assurance that we will be able to renew or replace the Unsecured Line of Credit upon maturity on favorable terms (including the lenders’ total commitment) or at all. The Unsecured Line of Credit is a recourse obligation of ours. Under the Unsecured Line of Credit, a facility fee equal to 0.125% per annum is payable in quarterly installments. The interest rate and facility fee are subject to adjustment in the event of a change in our unsecured debt ratings. 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 us at a negotiated LIBOR-based rate. 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 March 31, 2010, we had no borrowings and letters of credit totaling approximately $9.5 million outstanding under the Unsecured Line of Credit, with the ability to borrow $990.5 million. As of May 3, 2010, we had no borrowings outstanding under the Unsecured Line of Credit.

Our unsecured senior notes are redeemable at our option, in whole or in part, at a redemption price equal to the greater of (i) 100% of their principal amount or (ii) the sum of the present value of the remaining scheduled payments of principal and interest discounted at a rate equal to the yield on U.S. Treasury securities with a comparable maturity plus 35 basis points (or 25 basis points in the case of the $250 million of notes that mature on June 1, 2015 and 40 basis points in the case of the $700 million of notes that mature on October 15, 2019), in each case plus accrued and unpaid interest to the redemption date. 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 March 31, 2010, we believe we were in compliance with each of these financial restrictions and requirements.

On April 19, 2010, we completed a public offering of $700.0 million in aggregate principal amount of our 5.625% senior notes due 2020. The notes were priced at 99.891% of the principal amount to yield 5.638% to maturity. The aggregate net proceeds to us, after deducting underwriter discounts and offering expenses, was approximately $693.5 million. The notes mature on November 15, 2020, unless earlier redeemed. Our unsecured senior notes are redeemable at our option, in whole or in part, at a redemption price equal to the greater of (i) 100% of their principal amount or (ii) the sum of the present value of the remaining scheduled payments of principal and interest discounted at a rate equal to the yield on U.S. Treasury securities with a comparable maturity plus 30 basis points. On April 7, 2010, in connection with the offering, we entered into two treasury lock agreements to fix the 10-year treasury rate at 3.873% per annum on notional amounts aggregating $350.0 million. We subsequently cash-settled the treasury lock agreements and received approximately $0.4 million, which amount will be recognized as a reduction to our interest expense over the ten-year term of the 5.625% senior notes due 2020.

(2) The initial exchange rate is 8.5051 shares per $1,000 principal amount of the notes (or an initial exchange price of approximately $117.58 per share of Boston Properties, Inc.’s common stock). In addition, we entered into capped call transactions with affiliates of certain of the initial purchasers, which are intended to reduce the potential dilution upon future exchange of the notes. The capped call transactions are expected to have the effect of increasing the effective exchange price to us of the notes from $117.58 to approximately $137.17 per share (subject to adjustment), representing an overall effective premium of approximately 40% over the closing price on August 13, 2008 of $97.98 per share of Boston Properties, Inc.’s common stock. The net cost of the capped call transactions was approximately $44.4 million.
(3) In connection with the special distribution of $5.98 per share of Boston Properties, Inc.’s common stock declared on December 17, 2007, the exchange rate was adjusted from 6.6090 to 7.0430 shares per $1,000 principal amount of notes effective as of December 31, 2007, resulting in an exchange price of approximately $141.98 per share of Boston Properties, Inc.’s common stock.
(4) Holders may require us to repurchase for cash the notes on February 15, 2012, 2017, 2022, 2027 and 2032 and at any time prior to their maturity upon a fundamental change, in each case at a price equal to 100% of the principal amount of the notes being repurchased plus any accrued and unpaid interest up to, but excluding, the repurchase date.
(5) In connection with the special distribution of $5.98 per share of Boston Properties, Inc.’s common stock declared on December 17, 2007, the exchange rate was adjusted from 9.3900 to 10.0066 shares per $1,000 principal amount of notes effective as of December 31, 2007, resulting in an exchange price of approximately $99.93 per share of Boston Properties, Inc.’s common stock.
(6) Holders may require us to repurchase for cash the notes on May 18, 2013 and May 15 of 2016, 2021, 2026 and 2031 and at any time prior to their maturity upon a fundamental change, in each case at a price equal to 100% of the principal amount of the notes being repurchased plus any accrued and unpaid interest up to, but excluding, the repurchase date.

During the first quarter of 2010, we repurchased approximately $53.6 million aggregate principal amount of our 2.875% exchangeable senior notes due 2037 for approximately $53.0 million. The repurchased notes had an aggregate carrying value of approximately $50.8 million, resulting in the recognition of a loss on extinguishment of approximately $2.2 million.

Off-Balance Sheet Arrangements-Joint Venture Indebtedness

We have investments in twelve unconsolidated joint ventures (including our investment in the Value-Added Fund) with our effective ownership interests ranging from 5% to 60%. Eleven 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 March 31, 2010, the aggregate debt, including both our and our partners’ share, incurred by these ventures was approximately $3.164 billion (of which our proportionate share is approximately $1.5 billion). The table below summarizes the outstanding debt of these joint venture properties at March 31, 2010. In addition to other guarantees specifically noted in the table, we have agreed to customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) on certain of the loans.

(3) The loan requires interest only payments with a balloon payment due at maturity.
(4) In connection with the assumption of the loan, we guaranteed the joint venture’s obligation to fund various escrows, including tenant improvements, taxes and insurance in lieu of cash deposits. As of March 31, 2010, the maximum funding obligation under the guarantee was approximately $16.3 million. We earn a fee from the joint venture for providing the guarantee and have an agreement with our partners to reimburse the joint venture for their share of any payments made under the guarantee.
(5) Principal amount does not include the assumed mezzanine loan with an aggregate principal amount of $294.0 million and a stated rate of 6.02% per annum, as the venture acquired the lenders’ interest in this loan for a purchase price of approximately $263.1 million in cash.
(6) In connection with the capitalization of the joint venture, loans in an aggregate of $450.0 million were funded by the venture’s partners on a pro-rata basis. Our share of the partner loans totaling $270.0 million has been reflected in Related Party Note Receivable on our Consolidated Balance Sheets.
(7) In connection with the refinancing of this property’s secured loan by the joint venture, we have guaranteed the joint venture’s obligation to fund an escrow related to certain lease rollover costs in lieu of an initial cash deposit for the full amount. The maximum funding obligation under the guarantee was $21.3 million. At closing, the joint venture funded a $10.0 million cash deposit into an escrow account and the remaining $11.3 million will be further reduced with scheduled monthly deposits from operating cash flows. We earn a fee from the joint venture for providing the guarantee and have an agreement with the outside partners to reimburse the joint venture for their share of any payments made under the guarantee.
(8) On April 9, 2010, the joint venture refinanced this mortgage. The new mortgage loan totaling $180.0 million bears interest at a fixed rate of 6.00% per annum and matures on April 10, 2015. In connection with the refinancing, the joint venture repaid $10.0 million of the previous mortgage loan utilizing cash contributions from the joint venture’s partners on a pro rata basis.
(9) In connection with the assumption of the loan, we guaranteed the joint venture’s obligation to fund tenant improvements and leasing commissions.

(12) An unconsolidated joint venture in which we own a 50% interest is the borrower of a $23.6 million mortgage financing collateralized by the land parcels at Eighth Avenue and 46th Street in New York City. We and our third-party joint venture partner each agreed to guarantee $11.8 million of the mortgage loan plus 50% of all other obligations agreed to by the borrower under the loan documents. The loan was scheduled to mature on May 8, 2009. However, because our partner is in discussions with the lender on a new credit facility, the lender has agreed that such loan amount need not be repaid pending finalization of the new credit facility. If our partner defaults on its obligation to contribute its share of the loan repayment amount, then we have the right to repay the entire loan amount, have the collateral released and proceed against our partner for reimbursement.
(13) The construction financing bears interest at a variable rate equal to LIBOR plus 1.20% per annum and matures on September 12, 2010 with two, one-year extensions options, subject to certain conditions. In addition, we have guaranteed the repayment of approximately $9.1 million of principal (as well as interest on the loan), which amount is subject to reduction and eventual elimination upon attaining certain debt service coverage ratios.
(14) This property is owned by the Value-Added Fund.
(15) Mortgage financing totals $26.0 million (of which approximately $24.3 million has been disbursed as of March 31, 2010). The mortgage bears interest at a variable rate of LIBOR plus 1.50% and matures on March 31, 2011 with two, one-year extension options.

The mortgage bears interest at a variable rate of LIBOR plus 1.75% and matures on May 31, 2011 with two, one-year extension options. The Value-Added Fund has guaranteed the payment of interest on the loan. In addition, the Value-Added Fund has entered into three interest rate swap contracts to fix the one-month LIBOR index rate at 3.63% per annum on an aggregate notional amount of $103 million. The swap contracts went into effect on June 2, 2008 and expires on April 1, 2011.
(17) The Value-Added Fund has guaranteed the payment of (1) an aggregate of approximately $5.0 million of unfunded tenant improvement costs and leasing commissions and (2) one year of real estate taxes.

On April 1, 2010, we acquired a 30% interest in a joint venture entity that owns 500 North Capitol Street, NW located in Washington, DC. 500 North Capitol Street is an approximately 180,000 net rentable square foot office property which is fully-leased to a single tenant through March 2011. On April 1, 2010, the joint venture entity refinanced at maturity the mortgage loan collateralized by the property totaling approximately $26.8 million. The new mortgage loan totaling $22.0 million bears interest at a variable rate equal to the greater of (1) the prime rate, as defined in the loan agreement, or (2) 5.75% per annum. The loan currently bears interest at 5.75% per annum and matures on March 31, 2013. Our investment in the joint venture totaling approximately $1.9 million was financed with cash contributions to the venture totaling approximately $1.4 million and the issuance to the seller of 5,906 common units of limited partnership interest in BPLP. The joint venture currently expects that it will remove the property from service and redevelop the property following the expiration of the lease in March 2011.

State and Local Tax Matters

Because Boston Properties, Inc. is organized and qualifies 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 (as amended, “TRIA”) was enacted in November 2002 to require regulated insurers to make available coverage for “certified” acts of terrorism (as defined by the statute). The expiration date of TRIA was extended to December 31, 2014 by the Terrorism Risk Insurance Program Reauthorization Act of 2007 (“TRIPRA”). Currently, the per occurrence limits of our portfolio property insurance program are $1.0 billion, including coverage for acts of terrorism certified under TRIA. We currently insure certain properties, including the General Motors Building located at 767 Fifth Avenue in New York, New York (“767 Fifth Avenue”), in a separate stand alone insurance program. The property insurance program per occurrence limits for 767 Fifth Avenue are $1.625 billion, including coverage for acts of terrorism certified under TRIA, with $1.375 billion of coverage for losses in excess of $250 million being provided by NYXP, LLC, as a direct insurer. We also currently carry nuclear, biological, chemical and radiological terrorism insurance coverage (“NBCR Coverage”) for acts of terrorism certified under TRIA, which is provided by IXP, LLC as a direct insurer, for the properties in our portfolio, including 767 Fifth Avenue, but excluding the properties owned by our Value-Added Fund and certain other properties owned in joint ventures with third parties or which we manage. The per occurrence limit for NBCR Coverage is $1 billion. 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.” The program trigger is $100 million and the coinsurance is 15%. Under TRIPRA, if the Federal Government pays out for a loss under TRIA, it is mandatory that the Federal Government recoup the full amount of the loss from insurers offering TRIA coverage after the payment of the loss pursuant to a formula in TRIPRA. We may elect to terminate the NBCR Coverage if the Federal Government seeks recoupment for losses paid under TRIA, if there is a change in our portfolio or for any other reason. 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,

 

51


Table of Contents

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. In addition, the amount of earthquake coverage could impact our ability to finance properties subject to earthquake risk. 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.

IXP LLC, (“IXP”), a captive insurance company which is a wholly-owned subsidiary, 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 acts of terrorism certified under TRIA. NYXP, LLC (“NYXP”), a captive insurance company which is a wholly-owned subsidiary, acts as a direct insurer with respect to a portion of our coverage for acts of terrorism certified under TRIA for 767 Fifth Avenue. Currently, NYXP only insures losses which exceed the program trigger under TRIA and NYXP reinsures with a third-party insurance company any coinsurance payable under TRIA. Insofar as we own IXP and NYXP, we are responsible for their liquidity and capital resources, and the accounts of IXP and NYXP 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. IXP and NYXP would also be responsible for any recoupment charges by the Federal Government in the event losses are paid out and their insurance policies are maintained after the payout by the Federal Government. If we experience a loss and IXP or NYXP are required to pay under their insurance policies, we would ultimately record the loss to the extent of the required payment. Therefore, insurance coverage provided by IXP and NYXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance.

The mortgages on our properties typically contain requirements concerning the financial ratings of the insurers who provide policies covering the property. We provide the lenders on a regular basis with the identity of the insurance companies in our insurance programs. The ratings of some of our insurers are below the rating requirements in some of our loan agreements and the lenders for these loans could attempt to claim an event of default has occurred under the loan. We believe we could obtain insurance with insurers which satisfy the rating requirements. Additionally, in the future our ability to obtain debt financing secured by individual properties, or the terms of such financing, may be adversely affected if lenders generally insist on ratings for insurers which are difficult to obtain or which result in a commercially unreasonable premium. There can be no assurance that a deficiency in the financial ratings of one or more of our insurers will not have a material adverse effect on us.

We continue to monitor the state of the insurance market in general, and the scope and costs of coverage for acts of terrorism and California earthquake risk 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 attributable to Boston Properties Limited Partnership (computed in accordance with GAAP, including non-recurring items) for gains (or losses) from sales of properties, real estate related

Table of Contents

depreciation and amortization, and after adjustment for unconsolidated partnerships and joint ventures. 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.

FFO should not be considered as an alternative to net income attributable to Boston Properties Limited Partnership (determined in accordance with GAAP) as an indication of our performance. FFO does not 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 should be compared with our reported net income attributable to Boston Properties Limited Partnership and considered in addition to cash flows in accordance with GAAP, as presented in our Consolidated Financial Statements.

The following table presents a reconciliation of net income available to common unitholders to FFO for the three months ended March 31, 2010 and 2009:

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.

ITEM 3—Quantitative and Qualitative Disclosures about Market Risk

As of March 31, 2010, approximately $6.3 billion of our consolidated borrowings bore interest at fixed rates and approximately $394.9 million of our consolidated borrowings bore interest at variable rates, and therefore the fair value of these instruments is affected by changes in the market interest rates. As of March 31, 2010, the weighted-average interest rate on our variable rate debt was LIBOR/Eurodollar plus 1.50% per annum (for an all in rate as of March 31, 2010 of 1.75% per annum). The GAAP weighted average interest rate on the variable rate debt as of March 31, 2010 was 1.97% per annum. The table below does not include our unconsolidated joint venture debt. For a discussion concerning our unconsolidated joint venture debt, refer to Note 4 to the Consolidated Financial Statements and “Item 2.—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capitalization—Off-Balance Sheet Arrangements—Joint Venture Indebtedness.”

Table of Contents

At March 31, 2010, the weighted-average coupon/stated rate on all of our fixed and variable rate debt was 5.44% and 1.75%, respectively. The weighted-average coupon/stated rate for our unsecured debt and unsecured exchangeable debt was 5.93% and 3.65%, respectively.

At March 31, 2010, our outstanding variable rate debt based on LIBOR totaled approximately $394.9 million. At March 31, 2010, the interest rate on our variable rate debt was approximately 1.97%. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $1.0 million for the three months ended March 31, 2010.

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 first quarter of our fiscal year ending December 31, 2010 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. Boston Properties, Inc 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.

Except to the extent updated below or 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 in Part I, “Item 2-Management’s Discussion and Analysis of Financial Condition and Results of Operations”), 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, 2009.

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 March 31, 2010, in connection with issuances of common stock by Boston Properties, Inc. pursuant to exercises of stock options and issuances to employees of restricted common stock under the Second Amendment and Restatement of the Boston Properties, Inc. 1997 Stock Option and Incentive Plan and pursuant to issuances under the Boston Properties, Inc. 1999 Non-Qualified Employee Stock Purchase Plan, we issued an aggregate of approximately 98,504 common units to Boston Properties, Inc. in exchange for approximately $1,217,120, 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.
