BOSTON, Oct. 24 /PRNewswire-FirstCall/ -- Boston Properties, Inc. (NYSE: BXP), a real estate investment trust, reported results today for the third quarter ended September 30, 2007.

Funds from Operations (FFO) for the quarter ended September 30, 2007 were $139.1 million, or $1.17 per share basic and $1.15 per share diluted, after a supplemental adjustment to exclude the loss from early extinguishment of debt associated with the sale of real estate. This compares to FFO for the quarter ended September 30, 2006 of $137.3 million, or $1.19 per share basic and $1.16 per share diluted. The loss from early extinguishment of debt associated with the sale of real estate totaled approximately $2.7 million, or $0.02 per share basic and diluted for the quarter ended September 30, 2007. FFO for the quarter ended September 30, 2007 includes the write-off of costs related to an abandoned suburban development project totaling approximately $4.5 million, or $0.03 per share basic and diluted. The weighted average number of basic and diluted shares outstanding totaled 119,010,269 and 122,298,400, respectively, for the quarter ended September 30, 2007 and 115,431,903 and 120,726,865, respectively, for the quarter ended September 30, 2006.

Net income available to common shareholders was $242.4 million for the three months ended September 30, 2007, compared to $108.0 million for the quarter ended September 30, 2006. Net income available to common shareholders per share (EPS) for the quarter ended September 30, 2007 was $2.02 basic and $1.99 on a diluted basis. This compares to EPS for the third quarter of 2006 of $0.93 basic and $0.91 on a diluted basis. EPS includes $1.38 and $0.18, on a diluted basis, related to gains on sales of real estate and discontinued operations for the quarters ended September 30, 2007 and 2006, respectively.

The reported results are unaudited and there can be no assurance that the results will not vary from the final information for the quarter ended September 30, 2007. In the opinion of management, all adjustments considered necessary for a fair presentation of these reported results have been made.

As of September 30, 2007, the Company's portfolio consisted of 138 properties comprising approximately 44.1 million square feet, including 13 properties under construction totaling 3.9 million square feet and one hotel. The overall percentage of leased space for the 124 properties in service as of September 30, 2007 was 93.9%.

Significant events of the third quarter include:

  • On July 12, 2007, the Company executed a lease with Ropes & Gray LLP to relocate its Boston office to the Prudential Tower. The law firm will occupy more than 400,000 square feet of office space in the top floors of the 52-story, 1.2 million square foot office building beginning in the fall of 2010.
  • On July 16, 2007, the Company entered into a joint venture with an unrelated third party to develop a Class A office complex aggregating approximately 425,000 net rentable square feet located in Anne Arundel County, Maryland. The joint venture partner contributed the land for a 50% interest in the joint venture and the Company will contribute cash of approximately $14.9 million for its 50% interest. The joint venture has commenced construction on an approximately 114,000 net rentable square foot Class A office property on the site. On September 13, 2007, the joint venture entity obtained construction financing totaling $45.5 million. The construction financing bears interest at a variable rate equal to LIBOR plus 1.20% per annum and matures in September 2010, with two one-year extension options.
  • On July 24, 2007, the Company acquired 701 Carnegie Center, a parcel of land located in Princeton, New Jersey for a purchase price of approximately $3.1 million. As previously announced, the Company entered into a lease agreement on June 11, 2007 with The Trustees of Princeton University for a build-to-suit project on the site with approximately 120,000 net rentable square feet of Class A office space. The Company expects that the building will be complete and available for occupancy during the fourth quarter of 2009.
  • On July 27, 2007, the Company commenced an interest rate hedging program for a portion of its anticipated financing activity in 2008. To date, the Company has entered into a series of treasury lock contracts and forward starting interest rate swap contracts on notional amounts aggregating $450.0 million for 10-year fixed rate financings estimated to occur on or about April 1, 2008 and on or about July 31, 2008. The contracts have fixed the 10-year treasury rate at a weighted average rate of 4.68%.
  • On August 6, 2007, the Company used available cash to repay the mortgage loan collateralized by its Embarcadero Center Four property located in San Francisco, California totaling approximately $131.2 million. There was no prepayment penalty associated with the repayment. The mortgage loan bore interest at a fixed rate of 6.79% per annum and was scheduled to mature on February 1, 2008.
  • On August 7, 2007, the Company sold Democracy Center in Bethesda, Maryland, for approximately $280.5 million. Democracy Center is a Class A office complex that contains an aggregate of approximately 685,000 net rentable square feet. In conjunction with the sale, the Company repaid the mortgage financing collateralized by the property totaling approximately $94.6 million. The Company paid a prepayment fee of approximately $2.6 million associated with the repayment. The mortgage loan bore interest at a fixed rate equal to 7.05% per annum and was scheduled to mature on April 1, 2009.
  • On September 27, 2007, the Company executed a contract to acquire North First Business Park located in San Jose, California, at a purchase price of approximately $71.5 million. This property is comprised of eight office/technical properties aggregating approximately 367,000 net rentable square feet located on approximately 24 acres of land. The Company expects to redevelop this site into approximately 1.4 million net rentable square feet of Class A office space. The acquisition is subject to the satisfaction of customary closing conditions and there can be no assurance that the acquisition will be consummated on the terms currently contemplated or at all.
  • On September 27, 2007, the Company entered into an interest rate swap contract to fix the one-month LIBOR index rate at 4.57% per annum on a construction loan with a notional amount of $96.7 million. The swap contract went into effect on October 22, 2007 and expires on October 29, 2008.

Transactions completed subsequent to September 30, 2007:

  • On October 1, 2007, a joint venture in which the Company has a 50% interest, placed in-service 505 9th Street, a 323,000 net rentable square foot Class A office property located in Washington, D.C. The building is 97% leased. On October 17, 2007, the construction financing on the property was converted to a 10-year fixed rate loan that matures on November 1, 2017. The loan totals $130.0 million and bears interest at a fixed interest rate of 5.73% per annum.
  • On October 1, 2007, the Company used available cash to repay the mortgage loan collateralized by its 504, 506, 508 and 510 Carnegie Center properties located in Princeton, New Jersey totaling approximately $65.0 million.

EPS and FFO per Share Guidance:

The Company's guidance for the fourth quarter 2007 and full year 2008 for EPS (diluted) and FFO per share (diluted) is set forth and reconciled below. In addition to the assumptions described below the table, the guidance for the full year 2008 assumes that the Company's Board of Directors declares a special dividend in the amount of $5.70 per common share/unit in December 2007, payable by the end of January 2008, primarily relating to gains on sales of assets (including 5 Times Square); there can be no assurance, however, as to the exact amount or timing of this special dividend.



                              Fourth Quarter 2007          Full Year 2008
                              Low      -      High      Low      -      High
    Projected EPS (diluted) $1.12      -     $1.13    $2.52      -     $2.62

    Add:
     Projected Company Share
      of Real Estate
      Depreciation and
      Amortization           0.51      -      0.51     2.10      -      2.10
    Less:
    Projected Company Share
     of Gains on Sales of
     Real Estate             0.45      -      0.45     0.00      -      0.00

    Projected FFO per Share
     (diluted)              $1.18      -     $1.19    $4.62      -     $4.72

The foregoing estimates reflect management's view of current and future market conditions, including assumptions with respect to rental rates, occupancy levels and the earnings impact of the events referenced in this release. The estimates do not include possible future gains or losses or the impact on operating results from other possible future property acquisitions, dispositions or financings. EPS estimates may be subject to fluctuations as a result of several factors, including changes in the recognition of depreciation and amortization expense and any gains or losses associated with disposition activity. The Company is not able to assess at this time the potential impact of these factors on projected EPS. By definition, FFO does not include real estate-related depreciation and amortization or gains or losses associated with disposition activities. There can be no assurance that the Company's actual results will not differ materially from the estimates set forth above.

On August 31, 2007, the Financial Accounting Standards Board (the "FASB") issued proposed FASB Staff Position No. APB 14-a "Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement)" (the "proposed FSP") that would require the liability and equity components of convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement) to be separately accounted for in a manner that reflects the issuer's nonconvertible debt borrowing rate. As disclosed in the Company's most recent Form 10-Q, the proposed FSP, if issued as currently contemplated, would require that the initial debt proceeds from the sale of Boston Properties Limited Partnership's ("BPLP") $862.5 million of 2.875% exchangeable senior notes due 2037 and $450.0 million of 3.75% exchangeable senior notes due 2036 be allocated between a liability component and an equity component in a manner that reflects interest expense at the interest rate of similar nonconvertible debt. The resulting debt discount would be amortized over the period during which the debt is expected to be outstanding (i.e., through the first optional redemption dates) as additional non-cash interest expense. The proposed FSP would be effective for fiscal years beginning after December 15, 2007 and interim periods within those fiscal years, and it would be applied retrospectively to BPLP's outstanding exchangeable senior notes for all periods presented. Based on the Company's current understanding of the application of the proposed FSP, this would result in an aggregate of approximately $0.13 - $0.14 per share (net of incremental capitalized interest) of additional non-cash interest expense for fiscal 2008. Excluding the impact of capitalized interest, the additional non-cash interest expense would be approximately $0.15 - $0.16 per share, and this amount (before netting) will increase in subsequent reporting periods through the first optional redemption dates as the debt accretes to its par value over the same period. There can be no assurance that the proposed FSP will be issued in the form currently contemplated by the FASB, or at all, and therefore its ultimate impact on the Company's interest expense may differ materially from the aforementioned estimate. Accordingly, the guidance set forth in the table above also does not include the potential impact of the proposed FSP.

    (1) Pursuant to the revised definition of Funds from Operations adopted by
        the Board of Governors of the National Association of Real Estate
        Investment Trusts ("NAREIT"), we calculate Funds from Operations, or
        "FFO," by adjusting net income (loss) (computed in accordance with
        GAAP, including non-recurring items) for gains (or losses) from sales
        of properties, real estate related depreciation and amortization, and
        after adjustment for unconsolidated partnerships 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.

        In addition to presenting FFO in accordance with the NAREIT
        definition, we also disclose FFO after a specific and defined
        supplemental adjustment to exclude losses from early extinguishments
        of debt associated with the sales of real estate.  The adjustment to
        exclude losses from early extinguishments of debt results when the
        sale of real estate encumbered by debt requires us to pay the
        extinguishment costs prior to the debt's stated maturity and to write-
        off unamortized loan costs at the date of the extinguishment.  Such
        costs are excluded from the gains on sales of real estate reported in
        accordance with GAAP.  However, we view the losses from early
        extinguishments of debt associated with the sales of real estate as an
        incremental cost of the sale transactions because we extinguished the
        debt in connection with the consummation of the sale transactions and
        we had no intent to extinguish the debt absent such transactions.  We
        believe that this supplemental adjustment more appropriately reflects
        the results of

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

        Neither FFO nor FFO as adjusted should be considered as an alternative
        to net income (determined in accordance with GAAP) as an indication of
        our performance.  Neither FFO nor FFO as adjusted represents cash
        generated from operating activities determined in accordance with
        GAAP, and neither is a measure of liquidity or an indicator of our
        ability to make cash distributions.  We believe that to further
        understand our performance, FFO and FFO as adjusted should be compared
        with our reported net income and considered in addition to cash flows
        in accordance with GAAP, as presented in our consolidated financial
        statements.

    (2) Real estate depreciation and amortization consists of depreciation and
        amortization from the Consolidated Statements of Operations of
        $71,616, $70,558, $216,715 and $203,640, our share of unconsolidated
        joint venture real estate depreciation and amortization of $1,989,
        $2,253, $6,173 and $6,837 and depreciation and amortization from
        discontinued operations of $0, $990, $608 and $2,667, less corporate-
        related depreciation and amortization of $410, $393, $1,157 and $1,289
        for the three months and nine months ended September 30, 2007 and
        2006, respectively.

    (3) Excludes approximately $15.5 million related to our share of the gain
        on sale and related loss from early extinguishment of debt associated
        with the sale of Worldgate Plaza for the nine months ended September
        30, 2007.  Excludes approximately $17.9 million related to our share
        of the gain on sale and related loss from early extinguishment of debt
        associated with the sale 265 Franklin Street for the three and nine
        months ended September 30, 2006.

    (4) Excludes an adjustment of approximately $3.1 million for the nine
        months ended September 30, 2007 to the income allocated to the holders
        of Series Two Preferred Units to account for their right to
        participate on an as-converted basis in the special dividend that
        followed previously completed sales of real estate.
