Organization /b/font/p p style="margin-top: 6px; text-indent: 4%; margin-bottom: 0px;"font style="font-family: Times New Roman;" class="_mt" size="2"Boston Properties, Inc. (the "Company"), a Delaware corporation, is a self-administered and self-managed real estate investment trust ("REIT"). The Company is the sole general partner of Boston Properties Limited Partnership (the "Operating Partnership") and at Junenbsp;30, 2010 owned an approximate font class="_mt"85.9/font% font class="_mt"(85.9/font% at Junenbsp;30, 2009) general and limited partnership interest in the Operating Partnership. Partnership interests in the Operating Partnership 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. /font/p p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"font style="font-family: Times New Roman;" class="_mt" size="2"Unless specifically noted otherwise, all references to OP Units exclude units held by the Company. A holder of an OP Unit may present such OP Unit to the Operating Partnership 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 Operating Partnership is obligated to redeem such OP Unit for cash equal to the then value of a share of common stock of the Company ("Common Stock"). In lieu of a cash redemption, the Company 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 the Company 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 the Company. 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 9). /font/p p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"font style="font-family: Times New Roman;" class="_mt" size="2"At Junenbsp;30, 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 Operating Partnership. Preferred Units may also be converted into OP Units or redeemed for cash at the election of the holder thereof or the Operating Partnership in accordance with the terms and conditions set forth in the applicable amendment to the partnership agreement (See Note 9). /font/p p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"font style="font-family: Times New Roman;" class="_mt" size="2"All references herein to the Company refer to Boston Properties, Inc. and its consolidated subsidiaries, including the Operating Partnership, collectively, unless the context otherwise requires. /font/p p style="margin-top: 18px; margin-bottom: 0px;"font style="font-family: Times New Roman;" class="_mt" size="2"biProperties /i/b/font/p p style="margin-top: 6px; text-indent: 4%; margin-bottom: 0px;"font style="font-family: Times New Roman;" class="_mt" size="2"At Junenbsp;30, 2010, the Company owned or had interests in a portfolio ofnbsp;font class="_mt"144/font commercial real estate properties (the "Properties") aggregating approximatelynbsp;font class="_mt"37.8/fontnbsp;million net rentable square feet, including four properties under construction totaling approximatelynbsp;font class="_mt"1.6/fontnbsp;million net rentable square feet.

The Company accounts for its investment in the Value-Added Fund using the equity method of accounting.

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 in come. /font/p p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"font style="font-family: Times New Roman;" class="_mt" size="2"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 ye ar 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.nbsp;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 Decembernbsp;31, 2009. /font/pfont style="font-family: Times New Roman;" class="_mt" size="2" /font p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"font style="font-family: Times New Roman;" class="_mt" size="2"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 current market rates for similar securities. In determining the current market rates, 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.

During the six months ended Junenbsp;30, 2009, the Company recognized costs aggregating approximately $font class="_mt"27.8/font million related to the suspension of development, which amount included a $font class="_mt"20.0/font 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 Januarynbsp;19, 2010, the Company paid $font class="_mt"12.8/font million related to the t ermination of the lease agreement. As a result, the Company recognized approximately $font class="_mt"7.2/font million of income during the six months ended Junenbsp;30, 2010. /font/p p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"font style="font-family: Times New Roman;" class="_mt" size="2"On Junenbsp;1, 2010, the Company placed in-service Weston Corporate Center, an approximatelynbsp;font class="_mt"356,000/font net rentable square foot Classnbsp;A office property located in Weston, Massachusetts.

The Company had previously entered into a development management agreement with the buyer to develop a Classnbsp;A office property on the parcel totaling approximatelynbsp;font class="_mt"165,000/font 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 six months ended Junenbsp;30, 2010, the Company completed construction of the project and recognized the remaining gain on sale totaling approximately $font class="_mt"1.8/font m illion. The Company has recognized a cumulative gain on sale of approximately $font class="_mt"23.4/font million. /font/p p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;"font style="font-family: Times New Roman;" class="_mt" size="2"On Maynbsp;5, 2010, the Company satisfied the requirements of its master lease agreement related to the 2006 sale of 280 Park Avenue in New York City, resulting in the recognition of the remaining deferred gain on sale of real estate totaling approximately $font class="_mt"1.0/font million.
