COMPANY PROFILE

The Company

Boston Properties, Inc. (the “Company”), a self-administered and self-managed real estate investment trust (REIT), is one of the largest owners, managers, and developers of first-class office properties in the United States, with a significant presence in four markets: Boston, New York, San Francisco, and Washington, DC. The Company was founded in 1970 by Mortimer B. Zuckerman and Edward H. Linde in Boston, where it maintains its headquarters. Boston Properties became a public company in June 1997. The Company acquires, develops and manages its properties through full-service regional offices. Its property portfolio is comprised primarily of first-class office space, one hotel, three residential properties and five retail properties. Boston Properties is well-known for its in-house building management expertise and responsiveness to tenants’ needs. The Company holds a superior track record in developing premium Central Business District (CBD) office buildings, successful mixed use complexes, suburban office centers and build-to-suit projects for the U.S. government and a diverse array of creditworthy tenants.

Management

Boston Properties’ senior management team is among the most respected and accomplished in the REIT industry. Our deep and talented team of 32 individuals averages 30 years of real estate experience and nineteen years with Boston Properties. We believe that our size, management depth, financial strength, reputation, and relationships of key personnel provide a competitive advantage to realize growth through property development and acquisitions. Boston Properties benefits from the reputation and relationships of key personnel, including Mortimer B. Zuckerman, Executive Chairman; Owen D. Thomas, Chief Executive Officer; Douglas T. Linde, President; Raymond A. Ritchey, Executive Vice President, National Director of Acquisitions and Development; and Michael E. LaBelle, Senior Vice President, Chief Financial Officer. Our senior management team’s national reputation helps us attract business and investment opportunities. In addition, our other senior officers that serve as Regional Managers have strong reputations that assist in identifying and closing on new opportunities, having opportunities brought to us, and in negotiating with tenants and build-to-suit prospects. Additionally, Boston Properties’ Board of Directors consists of eleven distinguished members, the majority of whom are Independent Directors.

Strategy

Boston Properties’ primary business objective is to maximize return on investment in an effort to provide its investors with the greatest possible total return in all points of the economic cycle. To achieve this objective, the Company maintains consistent strategies that include the following:

• concentrating on carefully targeted markets characterized by high barriers to the creation of new supply and strong real estate fundamentals where tenants have demonstrated a preference for high-quality office buildings and other facilities;

• selectively acquiring assets which increase its penetration in these targeted markets;

• taking on complex, technically-challenging development projects that leverage the skills of its management team to successfully develop, acquire, and reposition properties;

• exploring joint-venture opportunities with partners who seek to benefit from the Company’s depth of development and management expertise;

• pursuing on a selective basis the sale of properties or interests therein to either take advantage of the demand for its premier properties or pare from the portfolio properties that have slower future growth potential; and

• continuing to enhance the Company’s balanced capital structure through its access to a variety of capital sources.

Senior Unsecured Debt Covenant Compliance Ratios

(in thousands)

In the fourth quarter of 2002, the Company’s operating partnership (Boston Properties Limited Partnership) received investment grade ratings on its senior unsecured debt securities and thereafter issued unsecured notes. The notes were issued under an indenture, dated as of December 13, 2002, by and between Boston Properties Limited Partnership and The Bank of New York Mellon Trust Company, N.A., as trustee, as supplemented, which, among other things, requires us to comply with the following limitations on incurrence of debt: Limitation on Outstanding Debt; Limitation on Secured Debt; Ratio of Annualized Consolidated EBITDA to Annualized Interest Expense; and Maintenance of Unencumbered Assets. Compliance with these restrictive covenants requires us to apply specialized terms the meanings of which are described in detail in our filings with the SEC, and to calculate ratios in the manner prescribed by the indenture.

This section presents such ratios as of September 30, 2014 to show that the Company’s Operating Partnership was in compliance with the terms of the indenture, as amended, which has been filed with the SEC. This section also presents certain other indenture-related data which we believe assists investors in the Company’s unsecured debt securities. Management is not presenting these ratios and the related calculations for any other purpose or for any other period, and is not intending for these measures to otherwise provide information to investors about the Company’s financial condition or results of operations. Investors should not rely on these measures other than for purposes of testing our compliance with the indenture.

Definitions

This section contains an explanation of certain non-GAAP financial measures we provide in other sections of this document, as well as the reasons why management believes these measures provide useful information to investors about the Company’s financial condition or results of operations. Additional detail can be found in the Company’s most recent annual report on Form 10-K and quarterly report on Form 10-Q, as well as other documents filed with or furnished to the SEC from time to time.

Funds from Operations

Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”), we calculate Funds from Operations, or “FFO,” by adjusting net income (loss) attributable to Boston Properties, Inc. (computed in accordance with GAAP, including non-recurring items) for gains (or losses) from sales of properties, impairment losses on depreciable real estate of consolidated entities, impairment losses on investments in unconsolidated joint ventures driven by a measurable decrease in the fair value of depreciable real estate held by the unconsolidated joint ventures, 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 asset sales (land and property), impairment losses and 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, Inc. (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, Inc. and considered in addition to cash flows determined in accordance with GAAP, as presented in our consolidated financial statements.

Funds Available for Distribution (FAD)

In addition to FFO, we present Funds Available for Distribution (FAD) by (1) adding to FFO non-real estate depreciation, fair value interest adjustment, losses from early extinguishments of debt, ASC 470-20 (formerly known as FSP APB 14-1) interest expense adjustment, non-cash stock-based compensation expense, and partners’ share of joint venture 2nd generation tenant improvement and leasing commissions (included in the period in which the lease commences), (2) eliminating the effects of straight-line rent and fair value lease revenue, (3) subtracting: recurring capital expenditures; hotel improvements, equipment upgrades and replacements; and 2nd generation tenant improvement and leasing commissions (included in the period in which the lease commences); and (4) subtracting from FFO non-cash termination adjustment. Although our FAD may not be comparable to that of other REITs and real estate companies, we believe it provides a meaningful indicator of our ability to fund cash needs and to make cash distributions to equity owners. In addition, we believe that to further understand our liquidity, FAD should be compared with our cash flows determined in accordance with GAAP, as presented in our consolidated financial statements. FAD does not represent cash generated from operating activities determined in accordance with GAAP, and FAD should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), or as a measure of our liquidity.

Total Consolidated Debt to Total Consolidated Market Capitalization Ratio

Total consolidated debt to total consolidated market capitalization ratio, defined as total consolidated debt as a percentage of the market value of our outstanding equity securities plus our total consolidated debt, is a measure of leverage commonly used by analysts in the REIT sector. Total consolidated market capitalization is the sum of (A) our total consolidated indebtedness outstanding plus (B) the market value of our outstanding equity securities calculated using the closing price per share of common stock of the Company multiplied by the sum of (1) outstanding shares of common stock of the Company, (2) outstanding common units of limited partnership interest in Boston Properties Limited Partnership (excluding common units held by the Company), (3) common units issuable upon conversion of all outstanding Series Two Preferred Units of partnership interest in Boston Properties Limited Partnership (all of which have been converted as of May 12, 2014) and (4) common units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units plus (C) outstanding Series Four Preferred Units of partnership interest in Boston Properties Limited Partnership multiplied by the fixed liquidation preference of $50 per unit plus (D) outstanding shares of 5.25% Series B Cumulative Redeemable Preferred Stock multiplied by the fixed liquidation preference of $2,500 per share. The calculation of total consolidated market capitalization does not include LTIP Units issued in the form of performance-based awards (OPP Awards and MYLTIP Awards) because, unlike other LTIP Units, they are not earned until certain performance thresholds are achieved. We are presenting this ratio because our degree of leverage could affect our ability to obtain additional financing for working capital, capital expenditures, acquisitions, development or other general corporate purposes. Investors should understand that our total consolidated debt to total consolidated market capitalization ratio is in part a function of the market price of the common stock of the Company, and as such will fluctuate with changes in such price 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 total 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 the ratio of indebtedness to other measures of asset value used by financial analysts and other financial ratios, as well as the various components of our outstanding indebtedness.

Total Adjusted Debt to Total Adjusted Market Capitalization Ratio

Total adjusted debt to total adjusted market capitalization ratio, defined as total adjusted debt (which equals our total consolidated debt, plus our share of unconsolidated joint venture debt, minus our joint venture partners’ share of consolidated debt) as a percentage of the market value of our outstanding equity securities plus our total adjusted debt, is an alternative measure of leverage used by some analysts in the REIT sector. Total adjusted market capitalization is the sum of (A) our total adjusted debt plus (B) the market value of our outstanding equity securities calculated using the closing price per share of common stock of the Company multiplied by the sum of (1) outstanding shares of common stock of the Company, (2) outstanding common units of limited partnership interest in Boston Properties Limited Partnership (excluding common units held by the Company), (3) common units issuable upon conversion of all outstanding Series Two Preferred Units of partnership interest in Boston Properties Limited Partnership (all of which have been converted as of May 12, 2014) and (4) common units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units plus (C) outstanding Series Four Preferred Units of partnership interest in Boston Properties Limited Partnership multiplied by the fixed liquidation preference of $50 per unit plus (D) outstanding shares of 5.25% Series B Cumulative Redeemable Preferred Stock multiplied by the fixed liquidation preference of $2,500 per share. The calculation of total adjusted market capitalization does not include performance-based awards because, unlike other LTIP Units, they are not earned until certain performance thresholds are achieved.

We present this ratio because, following the consolidation of 767 Venture, LLC (the entity that owns 767 Fifth Avenue (The GM Building)) effective June 1, 2013, our consolidated debt increased significantly compared to prior periods even though our economic interest in 767 Venture, LLC remained substantially unchanged. We believe the presentation of total adjusted debt may provide investors with a more complete picture of our share of consolidated and unconsolidated debt. In addition, in light of the difference between our total consolidated debt and our total adjusted debt, we believe that also presenting our total adjusted debt to total adjusted market capitalization may provide investors with a more complete picture of our leverage in relation to the overall size of our company. Investors should understand that our total adjusted debt to total adjusted market capitalization ratio is in part a function of the market price of the common stock of the Company, and as such will fluctuate with changes in such price and does not necessarily reflect our capacity to incur additional debt to finance our activities or our ability to manage our existing debt obligations. The total adjusted debt to total adjusted market capitalization ratio should be evaluated along with the ratio of indebtedness to other measures of asset value used by financial analysts and other financial ratios, as well as the various components of our outstanding indebtedness.

Consolidated Net Operating Income (NOI)

Consolidated NOI is a non-GAAP financial measure equal to net income attributable to Boston Properties, Inc., the most directly comparable GAAP financial measure, plus net income attributable to noncontrolling interests, less discontinued operations and gains on sales of real estate, plus corporate general and administrative expense, transaction costs, depreciation and amortization and interest expense, less development and management services income, income from unconsolidated joint ventures, gains on consolidation of joint ventures, interest and other income, gains (losses) from investments in securities and gains (losses) from early extinguishments of debt. In some cases we also present Consolidated NOI on a cash basis, which is Consolidated NOI after eliminating the effects of straight-lining of rent and fair value lease revenue and lease transaction costs which qualify as inducements in accordance with GAAP. We use Consolidated NOI internally as a performance measure and believe Consolidated 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 Consolidated NOI is a useful measure for evaluating the operating performance of our real estate assets. Our management also uses Consolidated NOI to evaluate regional property level performance and to make decisions about resource allocations. Further, we believe Consolidated NOI is useful to investors as a performance measure because, when compared across periods, Consolidated 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. Consolidated NOI excludes certain components from net income in order to provide results that are more closely related to a property’s results of operations. For example, interest expense is not necessarily linked to the operating performance of a real estate asset and is often incurred at the corporate level as opposed to the property level. In addition, depreciation and amortization, because of historical cost accounting and useful life estimates, may distort operating performance at the property level. Consolidated NOI presented by us may not be comparable to Consolidated NOI reported by other REITs that define Consolidated NOI differently. We believe that in order to facilitate a clear understanding of our operating results, Consolidated NOI should be examined in conjunction with net income as presented in our consolidated financial statements. Consolidated NOI should not be considered as an alternative to net income as an indication of our performance or to cash flows as a measure of our liquidity or ability to make distributions.

Combined Net Operating Income (NOI)

Combined NOI is a non-GAAP financial measure equal to Consolidated NOI plus our share of net operating income from unconsolidated joint ventures. In some cases we also present Combined NOI on a cash basis, which is Combined NOI after eliminating the effects of straight-lining of rent and fair value lease revenue and lease transaction costs which qualify as inducements in accordance with GAAP. In addition to Consolidated NOI, we use Combined NOI internally as a performance measure and believe Combined NOI provides useful information to investors regarding our financial condition and results of operations because it includes the impact of our unconsolidated joint ventures, which have become significant. Therefore, we believe Combined NOI is a useful measure for evaluating the operating performance of all of our real estate assets, including those held by our unconsolidated joint ventures. Our management also uses Combined NOI to evaluate regional property level performance and to make decisions about resource allocations. Further, like Consolidated NOI, we believe Combined NOI is useful to investors as a performance measure because, when compared across periods, Combined 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. Combined NOI presented by us may not be comparable to Combined NOI reported by other REITs that define Combined NOI differently. We believe that in order to facilitate a clear understanding of our operating results, Combined NOI should be examined in conjunction with net income as presented in our consolidated financial statements. Combined NOI should not be considered as an alternative to net income as an indication of our performance or to cash flows as a measure of our liquidity or ability to make distributions.

In-Service Properties

We treat a property as being “in-service” upon the earlier of (i) lease-up and completion of tenant improvements or (ii) one year after cessation of major construction activity under GAAP. The determination as to when a property should be treated as “in-service” involves a degree of judgment and is made by management based on the relevant facts and circumstances of the particular property. For portfolio operating and occupancy statistics we specify a single date for treating a property as “in-service” which is generally later than the date the property is partially placed in-service for GAAP. Under GAAP a property may be placed in service in stages as construction is completed and the property is held available for occupancy. In accordance with GAAP, when a portion of a property has been substantially completed and occupied or held available for occupancy, we cease capitalization on that portion, though we may not treat the property as being “in-service,” and continue to capitalize only those costs associated with the portion still under construction. In-service properties include properties held by our unconsolidated joint ventures. In-service Office and Office/Technical properties exclude hotel and residential properties.

Same Properties

In our analysis of NOI, particularly to make comparisons of NOI 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 “Same Properties.” “Same Properties” therefore exclude properties placed in-service, acquired, repositioned, or in development or redevelopment after the beginning of the earliest period presented or disposed of prior to the end of the latest period presented. Accordingly, it takes at least one year and one quarter after a property is acquired or treated as “in-service” for that property to be included in “Same Properties.” Pages 20-22 & 38 indicate by footnote the “In-Service Properties” which are not included in “Same Properties.” “Same Properties NOI” includes our share of net operating income from unconsolidated joint ventures.

Annualized Revenue

Rental obligations at the end of the reporting period, including contractual base rents, percentage rent and reimbursements from tenants under existing leases, multiplied by twelve. These annualized amounts exclude rent abatements and non-recurring items.

Future Annualized Revenue

Rental obligations including the sum of (i) contractual base rents at lease expiration and (ii) percentage rent and reimbursements from tenants at the end of the current reporting period, multiplied by twelve. These annualized amounts exclude rent abatements and non-recurring items.

Average Monthly Rental Rates

Average Rental Rates are calculated by the Company as rental revenue in accordance with GAAP, divided by the weighted monthly average number of occupied units.

Average Economic Occupancy

Average Economic Occupancy is defined as total possible revenue less vacancy loss as a percentage of total possible revenue. Total possible revenue is determined by valuing average occupied units at contract rates and average vacant units at Market Rents. Vacancy loss is determined by valuing vacant units at current Market Rents. By measuring vacant units at their Market Rents, Average Economic Occupancy takes into account the fact that units of different sizes and locations within a residential property have different economic impacts on a residential property’s total possible gross revenue.

Market Rents

Market Rents used by the Company in calculating Average Economic Occupancy are based on the current market rates set by the managers of the Company’s residential properties based on their experience in renting their residential property’s units and publicly available market data. Trends in market rents for a region as reported by others could vary. Market Rents for a period are based on the average Market Rents during that period and do not reflect any impact for cash concessions.

Average Physical Occupancy

Average Physical Occupancy is defined as the number of average occupied units divided by the total number of units, expressed as a percentage.
