EXPLANATORY NOTE
This report combines the Quarterly Reports on Form 10-Q for the period ended March 31,September 30, 2022 of Boston Properties, Inc. and Boston Properties Limited Partnership. Unless stated otherwise or the context otherwise requires, references to “BXP” mean Boston Properties, Inc., a Delaware corporation and real estate investment trust (“REIT”), and references to “BPLP” and the “Operating Partnership” mean Boston Properties Limited Partnership, a Delaware limited partnership. BPLP is the entity through which BXP conducts substantially all of its business and owns, either directly or through subsidiaries, substantially all of its assets. BXP is the sole general partner and also a limited partner of BPLP. As the sole general partner of BPLP, BXP has exclusive control of BPLP’s day-to-day management. Therefore, unless stated otherwise or the context requires, references to the “Company,” “we,” “us” and “our” mean collectively BXP, BPLP and those entities/subsidiaries consolidated by BXP.
As of March 31,September 30, 2022, BXP owned an approximate 89.6% ownership interest in BPLP. The remaining approximate 10.4% interest was owned by limited partners. The other limited partners of BPLP either (1) contributed their direct or indirect interests in properties to BPLP in exchange for common units or preferred units of limited partnership interest in BPLP or (2) received long-term incentive plan units of BPLP pursuant to BXP’s Stock Option and Incentive Plans, or both. Under the limited partnership agreement of BPLP, unitholders may present their common units of BPLP for redemption at any time (subject to restrictions agreed upon at the time of issuance of the units that may restrict such right for a period of time, generally one year from issuance). Upon presentation of a common unit for redemption, BPLP must redeem the unit for cash equal to the then value of a share of BXP’s common stock. In lieu of a cash redemption by BPLP, however, BXP may elect to acquire any common units so tendered by issuing shares of BXP common stock in exchange for the common units. If BXP so elects, its common stock will be exchanged for common units on a one-for-one basis. This one-for-one exchange ratio is subject to specified adjustments to prevent dilution. BXP generally expects that it will elect to issue its common stock in connection with each such presentation for redemption rather than having BPLP pay cash. With each such exchange or redemption, BXP’s percentage ownership in BPLP will increase. In addition, whenever BXP issues shares of its common stock other than to acquire common units of BPLP, BXP must contribute any net proceeds it receives to BPLP and BPLP must issue to BXP an equivalent number of common units of BPLP. This structure is commonly referred to as an umbrella partnership REIT, or UPREIT.
The Company believes that combining the Quarterly Reports on Form 10-Q of BXP and BPLP into this single report:
enhances investors’ understanding of BXP and BPLP by enabling them to view the business as a whole in the same manner as management views and operates the business;
eliminates duplicative disclosure and provides a more concise and readable presentation because a substantial portion of the disclosure applies to both BXP and BPLP; and
creates time and cost efficiencies through the preparation of one combined report instead of two separate reports.
The Company believes it is important to understand the few differences between BXP and BPLP in the context of how BXP and BPLP operate as a consolidated company. The financial results of BPLP are consolidated into the financial statements of BXP. BXP does not have any other significant assets, liabilities or operations, other than its investment in BPLP, nor does it have employees of its own. BPLP, not BXP, generally executes all significant business relationships other than transactions involving the securities of BXP. BPLP holds substantially all of the assets of BXP, including ownership interests in joint ventures. BPLP conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for the net proceeds from equity issuances by BXP, which are contributed to the capital of BPLP in exchange for common or preferred units of partnership in BPLP, as applicable, BPLP generates all remaining capital required by the Company’s business. These sources include working capital, net cash provided by operating activities, borrowings under its credit facilities, the issuance of secured and unsecured debt and equity securities and proceeds received from the disposition of certain properties and interests in joint ventures.
Shareholders’ equity, partners’ capital and noncontrolling interests are the main areas of difference between the consolidated financial statements of BXP and BPLP. The limited partners of BPLP are accounted for as partners’ capital in BPLP’s financial statements and as noncontrolling interests in BXP’s financial statements. The noncontrolling interests in BPLP’s financial statements include the interests of unaffiliated partners in various consolidated partnerships. The noncontrolling interests in BXP’s financial statements include the same

noncontrolling interests in BPLP and limited partners of BPLP. The differences between shareholders’ equity and partners’ capital result from differences in the equity issued atby each of BXP and BPLP levels.BPLP.
In addition, the consolidated financial statements of BXP and BPLP differ in total real estate assets resulting from previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor redemptions of common units of BPLP. This accounting resulted in a step-up of the real estate assets of BXP at the time of such redemptions, resulting in a difference between the net real estate of BXP as compared to BPLP of approximately $259.0$252.2 million, or 1.4%1.3% at March 31,September 30, 2022, and a corresponding difference in depreciation expense, impairment losses and gains on sales of real estate upon the sale of these properties having an allocation of the real estate step-up. The acquisition accounting was nullified on a prospective basis beginning in 2009 as a result of the Company’s adoption of a new accounting standard requiring any subsequent redemptions to be accounted for solely as an equity transaction.
To help investors better understand the key differences between BXP and BPLP, the following items in this report present information separately for BXP and BPLP:
Item 1. Financial Statements (unaudited), which includes the following specific disclosures for BXP and BPLP:

BOSTON PROPERTIES, INC. AND BOSTON PROPERTIES LIMITED PARTNERSHIP
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
1. Organization
BXP is a fully integrated, self-administered and self-managed REIT. BXP is the sole general partner of BPLP, its operating partnership, and at March 31,September 30, 2022 owned an approximate 89.6% (89.7% at December 31, 2021) general and limited partnership interest in BPLP. Unless stated otherwise or the context requires, the “Company” refers to BXP and its subsidiaries, including BPLP and its consolidated subsidiaries. Partnership interests in BPLP include:
common units of partnership interest (also referred to as “OP Units”) and
long term incentive units of partnership interest (also referred to as “LTIP Units”).
Unless specifically noted otherwise, all references to OP Units exclude units held by BXP. A holder of an OP Unit may present the OP Unit to BPLP 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 1one year from issuance). Upon presentation of an OP Unit for redemption, BPLP is obligated to redeem the OP Unit for cash equal to the value of a share of common stock of BXP (“Common Stock”). In lieu of such cash redemption, BXP may elect to acquire the OP Unit for 1one share of Common Stock. Because the number of shares of Common Stock outstanding at all times equals the number of OP Units that BXP owns, 1one share of Common Stock is generally the economic equivalent of 1one 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.
The Company uses LTIP Units as a form of time-based, restricted equity compensation and as a form of performance-based equity compensation for employees, and has previously granted LTIP Units in the form of (1) 2012 outperformance plan awards (“2012 OPP Units”) and (2) 2013 - 2022 multi-year, long-term incentive program awards (also referred to as “MYLTIP Units”), each of which, upon the satisfaction of certain performanceperformance-based and time-based vesting conditions, is convertible into one OP Unit. The three-year measurement periods for the 2012 OPP Units and the 2013 - 2019 MYLTIP Units have ended and BXP’s total stockholder return (“TSR”) was sufficient for employees to earn and therefore become eligible to vest in a portion of the awards. Unless and until they are earned, the rights, preferences and privileges of the 2020 - 2022 MYLTIP Units differ from other LTIP Units granted to employees (including the 2012 OPP Units and the 2013 - 2019 MYLTIP Units, which have been earned). Therefore, unless specifically noted otherwise, all references to LTIP Units exclude the 2020 - 2022 MYLTIP Units. LTIP Units (including the earned 2012 OPP Units and the earned 2013 - 2019 MYLTIP 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 Notes 78 and 11)12).
Properties
At March 31,September 30, 2022, the Company owned or had joint venture interests in a portfolio of 201193 commercial real estate properties (the “Properties”) aggregating approximately 53.153.5 million net rentable square feet of primarily Class A office properties,premier workplaces, including 1114 properties under construction/redevelopment totaling approximately 4.14.4 million net rentable square feet. At March 31,September 30, 2022, the Properties consisted of:
182173 office properties (including 1112 properties under construction/redevelopment);
12 retail properties;properties (including one property under redevelopment);
6seven residential properties;properties (including one property under construction); and
1one hotel.
The Company considers Class A office propertiespremier workplaces to be well-located buildings that are modern structures or have been modernized to compete with newer buildings and professionally managed and maintained. As such, these properties attract high-quality tenantsclients and command upper-tier rental rates.
2. Basis of Presentation and Summary of Significant Accounting Policies
BXP does not have any other significant assets, liabilities or operations, other than its investment in BPLP, nor does it have employees of its own. BPLP, not BXP, generally executes all significant business relationships other than transactions involving securities of BXP. All majority-owned subsidiaries and joint ventures over which the Company has financial and operating control and variable interest entities (“VIEs”) in which the Company has determined it is the primary beneficiary are included in the consolidated financial statements. All significant
1517

Table of Contents
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 generally accepted accounting principles (“GAAP”) for interim financial information and in conjunction with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the disclosures required by GAAP 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 GAAP.  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, 2021.
The Company bases its estimates on historical experience and on various other assumptions that it considers to be reasonable under the circumstances, including the impact of extraordinary events such as the coronavirus (“COVID-19”) pandemic, the results of which form the basis for making significant judgments about the carrying values of assets and liabilities, assessments of future collectability, and other areas of the financial statements that are impacted by the use of estimates. Actual results may differ from these estimates under different assumptions or conditions.
Variable Interest Entities (VIEs)
Consolidated VIEs are those for which the Company is considered to be the primary beneficiary of a VIE. The primary beneficiary is the entity that has a controlling financial interest in the VIE, which is defined by the entity having both of the following characteristics: (1) the power to direct the activities that, when taken together, most significantly impact the VIE’s performance and (2) the obligation to absorb losses or the right to receive the returns from the VIE that could potentially be significant to the VIE. The Company has determined that it is the primary beneficiary for 6six of the 7seven entities that are VIEs.
Consolidated Variable Interest Entities
As of March 31,September 30, 2022, BXP has identified 6six consolidated VIEs, including BPLP. Excluding BPLP, the VIEs consisted of the following 5five in-service properties: 767 Fifth Avenue (the General Motors Building), Times Square Tower, 601 Lexington Avenue, Atlantic Wharf Office Building and 100 Federal Street.
The Company consolidates these VIEs because it is the primary beneficiary.  The third parties’ interests in these consolidated entities (excluding BPLP’s interest) are reflected as noncontrolling interests in property partnerships in the accompanying consolidated financial statements (See Note 7)8).
In addition, BXP’s only significant asset is its investment in BPLP and, consequently, substantially all of BXP’s assets and liabilities are the assets and liabilities of BPLP.
Variable Interest Entities Not Consolidated
The Company has determined that the Platform 16 Holdings LP joint venture is a VIE. The Company does not consolidate this entity as the Company does not have the power to direct the activities that, when taken together, most significantly impact the VIE’s performance and, therefore, the Company is not considered to be the primary beneficiary.

In addition, the Company currently carries earthquake insurance which covers its Seattle region with a $60$110 million per occurrence limit, and a $60$110 million annual aggregate limit. This insurance is subject to a deductible in the amount of 2% of the value of the affected property. 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 or change the structure of its earthquake insurance program 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, 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 and Los Angeles properties and the Company’s NBCR Coverage. Insofar as the Company owns IXP, it is responsible for its liquidity and capital resources, and the accounts of IXP are part of the Company’s consolidated financial statements. In particular, if a loss occurs which is covered by the Company’s NBCR Coverage but is less than the applicable program trigger under TRIA, IXP would be responsible for the full amount of the loss without any backstop by the Federal Government. IXP would also be responsible for any recoupment charges by the Federal Government in the event losses are paid out and its insurance policy is maintained after the payout by the Federal Government. If the Company experiences a loss and IXP is required to pay under its insurance policy, the Company would ultimately record the loss to the extent of the required payment. Therefore, insurance coverage provided by IXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance. In addition, BPLP has issued a guarantee to cover liabilities of IXP in the amount of $20.0 million.
The Company continues to monitor the state of the insurance market in general, and the scope and costs of coverage for acts of terrorism, earthquakes and pandemics, 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, 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, pandemics 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.
7.8. Noncontrolling Interests

Prior to the end of the respective three-year performance period for each plan, holders of MYLTIP Units are 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,three-year performance period for each plan has ended, (1) the number of MYLTIP Units, both vested and unvested, that MYLTIP award recipients have earned, if any, based on the establishment of a performance pool, will be entitled to receive distributions in an amount per unit equal to distributions, both regular and special, payable on an OP Unit.Unit and (2) with respect to the 2021 MYLTIP and 2022 MYLTIP only, the Company will make a “catch-up” cash payment on the MYLTIP Units that are ultimately earned in an amount equal to the regular and special dividends, if any, declared during the performance period on Common Stock, less the distributions actually paid during the performance period on all of the awarded 2021 MYLTIP Units and 2022 MYLTIP Units.
On February 4, 2022, the measurement period for the Company’s 2019 MYLTIP awards ended and, based on BXP’s relative TSR performance, the final payout was determined to be 69.0% of target, or an aggregate of approximately $8.6 million (after giving effect to employee separations). As a result, an aggregate of 144,043 2019 MYLTIP Units that had been previously granted were automatically forfeited.

A holder of an OP Unit may present the OP Unit to BPLP 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 1one year from issuance). Upon presentation of an OP Unit for redemption, BPLP must redeem the OP Unit for cash equal to the then value of a share of Common Stock of BXP. BXP may, in its sole discretion, elect to assume and satisfy the redemption obligation by paying either cash or issuing 1one share of Common Stock. The value of the OP Units (LTIP(other than OP Units owned by BXP), and LTIP Units (including the 2012 OPP Units and 2013 - 2019 MYLTIP

Preferred Stock
On March 2, 2021, BXP issued a redemption notice for 80,000 shares of its 5.25% Series B Cumulative Redeemable Preferred Stock (the “Series B Preferred Stock”), which constituted all of the outstanding Series B Preferred Stock, and the corresponding depositary shares, each representing 1/100th of a share of Series B Preferred Stock. The redemption price per share of Series B Preferred Stock was $2,500, plus all accrued and unpaid dividends to, but not including, the redemption date, totaling $2,516.41 per share. On March 31, 2021, the Company transferred the full redemption price for all outstanding shares of Series B Preferred Stock, including accrued and unpaid dividends to, but not including, the redemption date, to the redemption agent.

Net operating income (“NOI”) is a non-GAAP financial measure equal to net income attributable to Boston Properties, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership common unitholders, as applicable, the most directly comparable GAAP financial measures, plus (1) preferred stock/unit redemption charge, preferred dividends/distributions, net income attributable to noncontrolling interests, interest expense, losses from early extinguishment of debt, loss from unconsolidated joint ventures, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts and corporate general and administrative expense less (2) gains (losses) from investments in securities, other income - assignment fee, interest and other income (loss), gains on sales of real estate, income from unconsolidated joint ventures, direct reimbursements of payroll and related costs from management services contracts and development and management services revenue. The Company believes NOI is useful to investors as a performance measure and believes it provides useful information to investors regarding its results of operations and financial condition because, when compared across periods, it 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, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership common unitholders. 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. Similarly, interest expense may be incurred at the property level even though the financing proceeds may be used at the corporate level (e.g., used for other investment activity). In addition, depreciation and amortization expense, because of historical cost accounting and useful life estimates, may distort operating performance measures at the
34

Table of Contents
property level. NOI presented by the Company may not be comparable to NOI reported by other REITs or real estate companies that define NOI differently.
27

Table of Contents
The Company’s internal reporting utilizes its share of NOI, which includes its share of NOI from consolidated and unconsolidated joint ventures, which is a non-GAAP financial measure that is calculated as the consolidated amount, plus the Company’s share of the amount from the Company’s unconsolidated joint ventures (calculated based upon the Company’s economic percentage ownership interest and, in some cases, after priority allocations), minusless the Company’s partners’ share of the amount from the Company’s consolidated joint ventures (calculated based upon the partners’ economic percentage ownership interests and, in some cases, after priority allocations, income allocation to private REIT shareholders and their share of fees due to the Company). The Company’s share of NOI from unconsolidated joint ventures does not include its share of losses from early extinguishment of debt from unconsolidated joint ventures,gains on sales of real estate from unconsolidated joint ventures and gain on sale of investment from unconsolidated joint ventures, both of which are included within LossIncome (Loss) From Unconsolidated Joint Ventures in the Company’s Consolidated Statements of Operations.  Management utilizes its share of NOI in assessing its performance as the Company has several significant joint ventures and, in some cases, the Company exercises significant influence over, but does not control, the joint venture, in which case GAAP requires that the Company account for the joint venture entity using the equity method of accounting and the Company does not consolidate it for financial reporting purposes. In other cases, GAAP requires that the Company consolidate the venture even though the Company’s partner(s) owns a significant percentage interest. As a result, the presentations of the Company’s share of NOI should not be considered a substitute for, and should only be considered together with and as a supplement to, the Company’s financial information presented in accordance with GAAP.
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. Preferred stock/unit redemption charge, preferred dividends/distributions, interest expense, losses from early extinguishment of debt, loss from unconsolidated joint ventures, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts, corporate general and administrative expense, gains (losses) from investments in securities, other income - assignment fee, interest and other income (loss), gains on sales of real estate, income from unconsolidated joint ventures, direct reimbursements of payroll and related costs from management services contracts and development and management services revenue are not included in NOI and are provided as reconciling items to the Company’s reconciliations of its share of NOI to net income attributable to common shareholders/unitholders.
The Company’s segments are based on the Company’s method of internal reporting which classifies its operations by geographic area. The Company’s segments by geographic area are Boston, Los Angeles, New York, San Francisco, Seattle and Washington, DC. On September 1, 2021, the Company invested in a joint venture that acquired Safeco Plaza located in Seattle, Washington. As such, the Seattle region was identified as a segment during the third quarter of 2021. The Company also presents information for each segment by property type, including Office, Residential and Hotel.

10.11. Earnings Per Share / Common Unit
BXP
The following table provides a reconciliation of both the net income attributable to Boston Properties, Inc. common shareholders and the number of common shares used in the computation of basic earnings per share (“EPS”), which is calculated by dividing net income attributable to Boston Properties, Inc. common shareholders by the weighted-average number of common shares outstanding during the period. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are also participating securities. As such, unvested restricted common stock of BXP and BPLP’s LTIP Units, 2012 OPP Units and MYLTIP Units are considered participating securities. Participating securities are included in the computation of basic EPS of BXP using the two-class method. Participating securities are included in the computation of diluted EPS of BXP using the if-converted method if the impact is dilutive. Because the 2012 OPP Units and 2013 - 2019 MYLTIP Units required, and the 2020 - 2022 MYLTIP Units require, BXP to outperform absolute and/or relative return thresholds, unless such thresholds have been met by the end of the applicable reporting period, BXP excludes such units from the diluted EPS calculation. Other potentially dilutive common shares, including stock options, restricted stock and other securities of BPLP that are exchangeable for BXP’s Common Stock, and the related impact on earnings, are considered when calculating diluted EPS.

The following table provides a reconciliation of both the net income attributable to Boston Properties Limited Partnership common unitholders 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 common unitholders by the weighted-average number of common units outstanding during the period. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are also participating securities. As such, unvested restricted common stock of BXP and BPLP’s LTIP Units, 2012 OPP Units and MYLTIP Units are considered participating securities. Participating securities are included in the computation of basic earnings per common unit using the two-class method. Participating securities are included in the computation of diluted earnings per common unit using the if-converted method if the impact is dilutive.

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 17,626,00017,662,000 and 17,089,00017,011,000 redeemable common units for the three months ended March 31,September 30, 2022 and 2021, respectively, and 17,631,000 and 17,016,000 redeemable common units for the nine months ended September 30, 2022 and 2021, respectively.

11.12. Stock Option and Incentive Plan
On February 1, 2022, BXP’s Compensation Committee approved the 2022 MYLTIP awards under the Boston Properties, Inc. 2021 Stock Option and Incentive Plan (the “2021 Plan”) to certain officers and employees of BXP. The 2022 MYLTIP awards consist of two, equally weighted (50% each) components that utilize BXP’s TSR over a three-year measurement period as the performance metric.
The first component of the 2022 MYLTIP represents one-half (50%) of the target grant-date value of the award. The number of LTIP Units that can be earned under this component ranges from zero to 200% of the target number of LTIP Units, based on BXP’s three-year, annualized relative TSR performance compared to a custom index of peer companies. Under this component, 100% of the target number of LTIP Units will be earned if BXP’s
42

Table of Contents
TSR equals the custom index TSR; for relative TSR performance between -1,000 basis points and +1,000 basis points, the number of LTIP Units earned will be determined using linear interpolation.
The second component represents the remaining one-half (50%) of the target grant-date value of the 2022 MYLTIP. The number of LTIP Units that can be earned under this component ranges from zero to 200% of the target number of LTIP Units, based on BXP’s non-annualized, cumulative absolute TSR during the three-year performance period. Under this component, 100% of the target number of LTIP Units will be earned if BXP achieves an absolute TSR equal to +1,000 basis points; if BXP’s absolute TSR is greater than -4,000 basis points but less than +6,000 basis points, then the number of LTIP Units earned will be determined using linear interpolation.
Total earned awards under the 2022 MYLTIP, if any, will equal the sum of the number of LTIP Units earned under the first and second components and will range from zero to a maximum of 254,061 LTIP Units with a target of approximately 127,031 LTIP Units and linear interpolation between zero and maximum. Earned awards (if any) will vest 100% on January 31, 2025, but may not be converted, redeemed, sold or otherwise transferred for one additional year thereafter. Vesting will be accelerated in the event of a change in control, termination of employment by BXP without cause, or termination of employment by the award recipient for good reason, death, disability or retirement. If there is a change of control prior to January 31, 2025, earned awards will be calculated based on TSR performance up to the date of the change of control. The 2022 MYLTIP awards are in the form of LTIP Units issued

on the grant date, and they are subject to forfeiture to the extent awards are not earned. Prior to the performance measurement date holders of the 2022 MYLTIP Units are only entitled to one-tenth (10%) of the regular quarterly distributions payable on common partnership units. Following the completion of the three-year performance period, BXPthe Company will also make a “catch-up” cash payment on the 2022 MYLTIP Units that are ultimately earned in an amount equal to the regular and special distributions, if any, declared during the performance period on BXP’s Common Stock, less the distributions actually paid to holders of 2022 MYLTIP Units during the performance period on all of the awarded 2022 MYLTIP Units. Under ASC 718 “Compensation - Stock Compensation,” the 2022 MYLTIP awards have an aggregate value of approximately $17.3 million, which amount will generally be amortized into earnings under the graded vesting method.
On February 4, 2022, the measurement period for the Company’s 2019 MYLTIP awards ended and, based on BXP’s relative TSR performance, the final payout was determined to be 69.0% of target, or an aggregate of approximately $8.6 million (after giving effect to employee separations). As a result, an aggregate of 144,043 2019 MYLTIP Units that had been previously granted were automatically forfeited.
During the threenine months ended March 31,September 30, 2022, BXP issued 33,41141,818 shares of restricted common stock and BPLP issued 250,893280,616 LTIP Units and 254,061 2022 MYLTIP Units to employees and non-employee directors under the 2021 Plan. Employees and non-employee directors paid $0.01 per share of restricted common stock and $0.25 per LTIP Unit and 2022 MYLTIP Unit. When issued, LTIP Units are not economically equivalent in value to a share of Common Stock, but over time can increase in value to one-for-one parity with Common Stock if there is sufficient appreciation in the value of the Company’s assets. The aggregate value of the LTIP Units is included in noncontrolling interests in the Consolidated Balance Sheets of Boston Properties, Inc.BXP and Boston Properties Limited Partnership.BPLP. A substantial majority of the grants of restricted common stock and LTIP Units to employees vest in four equal annual installments. Restricted common stock is measured at fair value on the date of grant based on the number of shares granted and the closing price of BXP’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. The shares of restricted common stock granted during the threenine months ended March 31,September 30, 2022 were valued at approximately $3.9$4.7 million ($113.79111.47 per share weighted-average). The LTIP Units granted were valued at approximately $27.2$29.9 million (approximately $108.41$106.46 per unit weighted-average fair value) using a Monte Carlo simulation method model. The per unit fair values of the LTIP Units granted were estimated on the dates of grant and for a substantial majority of such units were valued using the following assumptions: an expected life of 5.7 years, a risk-free interest rate of 1.71% and an expected price volatility of 31.0%. Because the 2012 OPP Units and 2013 - 2022 MYLTIP Units are subject to both a service condition and a market condition, the Company recognizes the related compensation expense under the graded vesting attribution method. Under the graded vesting attribution method, each portion of the award that vests at a different date is accounted for as a separate award and recognized over the period appropriate to that portion so that the compensation cost for each portion should be recognized in full by the time that portion vests. The Company recognizes forfeitures as they occur on its awards of stock-based compensation. Dividends paid on both vested and unvested shares of restricted stock are charged directly to Dividends in Excess of Earnings in Boston Properties, Inc.’s Consolidated Balance Sheets and Partners’ Capital in Boston Properties Limited Partnership’s Consolidated Balance Sheets. Aggregate stock-based compensation expense associated with restricted stock, LTIP Units and MYLTIP Units was approximately $20.9$7.7 million and $19.8$8.4 million for the three months

ended March 31,September 30, 2022 and 2021, respectively, and $43.2 million and $42.2 million for the nine months ended September 30, 2022 and 2021, respectively. At March 31,September 30, 2022, there was (1) an aggregate of approximately $37.0$25.9 million of unrecognized compensation expense related to unvested restricted stock, LTIP Units and 2019 MYLTIP Units and (2) an aggregate of approximately $16.0$7.3 million of unrecognized compensation expense related to unvested 2020 - 2022 MYLTIP Units that is expected to be recognized over a weighted-average period of approximately 2.32.0 years.

We caution you that, while forward-looking statements reflect our good-faith beliefs when we make them, they are not guarantees of future performance or occurrences 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.

The most significant factors that may cause actual results to differ materially from those expressed or implied by the forward-looking statements include the impact on global and U.S. economic conditions due to the ongoing COVID-19 pandemic, the ongoing war in Ukraine, risingcontinuing inflation, increasing interest rates, and supply-chain disruptions, as well as the risks described in (i) our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 including those described under the caption “Risk Factors,” (ii) our Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2022 including those described under the caption “Risk Factors,” (iii) our subsequent filings under the Exchange Act and (iii)(iv) the risk factors set forth in this Form 10-Q in Part II, Item 1A, if any.
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 risks and uncertainties related to the impact of (1) the COVID-19 global pandemic, including the emergence of additional variants, the effectiveness, availability and distribution of vaccines, including their efficacy against new variant strains and the willingness of individuals to be vaccinated, (2) the impact of geopolitical conflicts, including the war in Ukraine, and (3) the severity and duration of the indirect economic impacts of the foregoing, such as recession, supply chain disruptions, labor market disruptions, risingcontinued inflation, increasing interest rates, dislocation and volatility in capital markets, job losses, potential longer-term changes in consumer and tenantclient behavior, as well as possible future governmental responses;
volatile or adverse global economic and geopolitical conditions, health crises and dislocations in the credit markets could adversely affect our access to cost-effective capital and have a resulting material adverse effect on our business opportunities, results of operations and financial condition;
risks associated with downturns in the national and local economies, continued inflation, increasing interest rates, and volatility in the securities markets;
general risks affecting the real estate industry (including, without limitation, the inability to enter into or renew leases, tenantclient space utilization, dependence on tenants’clients’ 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;

Overview
BXP is one of the largest publicly traded office real estate investment trusts (REITs) (based on total market capitalization as of March 31,September 30, 2022) in the United States that develops, owns, and manages primarily Class A office properties.premier workplaces. Our properties are concentrated in six markets in the United States - Boston, Los Angeles, New York, San Francisco, Seattle, and Washington, DC. BPLP is the entity through which BXP conducts substantially all of its business and owns (either directly or through subsidiaries) substantially all of its assets. We generate revenue and cash primarily by leasing Class A office spacepremier workplaces to our clients. When making leasing decisions, we consider, among other things, the creditworthiness of the client and the industry in which it conducts business, the length of the lease, the rental rate to be paid at inception and throughout the lease term, the costs of tenant improvements, free rent periods and other landlord concessions, anticipated operating expenses and real estate taxes, current and anticipated vacancy in our properties and the market overall (including sublease space), current and expected future demand for the space, the impact of other client’s expansion rights and general economic factors.

Our core strategy has always been to develop, acquire and manage high-quality propertieshighest quality premier workplaces in supply-constrainedgateway markets with high barriers-to-entry and attractive demand drivers, and to focus on executing long-term leases with financially strong clients. Historically, these factors have minimized our exposure in weaker economic cycles and enhanced revenues as market conditions improve. Our client base is diverse across market sectors and

the weighted-average lease term for our in-place leases, excluding residential units, was approximately 7.97.8 years, as of March 31,September 30, 2022, including leases signed by our unconsolidated joint ventures. The weighted-average lease term for our 20 largest clients, based on leased square footage, was approximately 11.211.0 years as of March 31,September 30, 2022.
To be successful in any leasing environment, we believe we must consider all aspects of the client-landlord relationship. In this regard, we believe that our competitive leasing advantage is based on the following attributes:
our understanding of our client’s short- and long-term space utilization and amenity needs in the local markets;
our track record of developing and operating Class A office propertiespremier workplaces in a sustainable and responsible manner;
our reputation as a premier developer, owner and manager of primarily Class A office properties;the highest quality premier workplaces in our markets;
our financial strength and our ability to maintain high building standards; and
our relationships with local brokers.
Outlook
JustOver the last quarter, inflation has remained resilient. Although the U.S. GDP returned to growth in the third quarter after two consecutive quarterly contractions, consumer spending still slowed as inflation shrank buying power. The Federal Reserve remains committed to taming the Omicron variant’s impact on the economy beganfastest rising inflation in four decades by aggressively raising interest rates and are expected to slowly dissipate, geopolitical tensions in Eastern Europe increased uncertainty during the first quarter of 2022. Inflation, at generational highs, has caused food and energy prices to spike, thereby reducing consumer’s purchasing power and elevating the risks of an economic slowdown. At the same time, the labor market remains historically tight and companies continue to look to add employees, pushing unemployment lower.do so. This evolving operating environment impacts our operating activities as:
As business conditionsleaders may generally become more competitivereticent to make large capital allocation decisions, such as entry into a new lease, given the uncertain economic environment;
our capital costs have increased due to risinghigher interest rates slowing economic growth, and changes incredit spreads, and private market debt financing, both for construction and existing assets, is significantly more challenging to arrange; and
construction costs have increased for new development and, although the labor markets, business leaders will likely feelcosts for our active development pipeline are, at this stage, relatively fixed, the needcost of potential future developments continues to bring their employees together on a much more consistent basis and modify their return to office policies. We believe as employees return to their offices in greater numbers, our strategically located, high-quality office and well-amenitized properties will remain a vital componentincrease.

ensuringcontinuing to embrace our leadership position in the premier workplace industry and leveraging our strength in portfolio quality, client health, safetyrelationships, development skills, market penetration and satisfaction;sustainability to profitably build market share. Premier workplaces, the preferred choice for our current and prospective clients, are gaining market share and demonstrating the highest occupancy, net absorption levels and rental rates in the central business district (“CBD”) markets where we operate;

The following is an overview of leasing and investment activity in the firstthird quarter of 2022.
Leasing Activity and Occupancy
In the firstthird quarter of 2022, we signed approximately 1.21.4 million square feet of new leases and renewals, which is in line with our 10-year, pre-pandemic average forstrongest third quarter leasing for the first quarter.volume since 2019.

The overall occupancy of our in-service office and retail properties was 89.1%88.9% at March 31, 2022, an increase ofSeptember 30, basis points from December 31, 2021. Given our moderate near-term rollover, the amount of leases signed, but for which occupancy has not commenced, and the number of leases in negotiation for space in the in-service portfolio, we expect our occupancy to continue to increase.
Our parking and other revenue was approximately $21.7 million in the first quarter of 2022, a decrease of approximately $1.4 million, or 6%,60 basis points from the fourth quarter of 2021. Our hotel property, the Boston Marriott Cambridge, alsoJune 30, 2022. We experienced a decreaseslight decline in revenueoccupancy as we wait for recently signed leases to commence. We also removed three assets from our in-service portfolio: 601 Massachusetts Avenue, which was approximately 98% leased prior to its sale, 140 Kendrick Street Building A, which is now under redevelopment and 100% pre-leased, and 760 Boylston Street which is in redevelopment and 100% pre-leased.
The macroeconomic environment has resulted in softening demand in all of approximately $1.7 million, or 27%,our markets. While tours continue and leases under negotiation move forward, there is less urgency from the fourth quarter of 2021. We believe both decreasesclients to make new commitments. Potential clients touring space acknowledge that economic uncertainty is impacting space decisions. As we consider our expectations for leasing in 2023, we are correlated to the spikefactoring in the Omicron variant throughoutimpacts of a slower economy, softer business performance, and reduced demand for space. We expect the U.S. in the first partbulk of the quarter that delayed returnour leasing will continue to office openingscome from small and slowed down travel.medium-sized professional and financial services firms.
Investment Activity
We remain committed to developing and acquiring assets to enhance our long-term growth and to meet client demand for high-quality office, residential, and life sciences space. We continually evaluate current and prospective markets for possible acquisitions of “value-add” assets that require lease-up or repositioning, and acquisitions that are otherwise consistent with our long-term strategy of owning, managing, developing, and improving premier Class A propertiesworkplaces in each of our chosen markets.
Consistent with this strategy, on April 14,in September 2022, we further expanded our life sciences portfolio in Kendall Square in Cambridge, Massachusetts by completing the acquisition of 125 Broadway for a purchase price, including transaction costs, of approximately $592.4 million. 125 Broadway is a six-story, 271,000 square foot laboratory/life sciences property adjacent to our existing 2.2 million square foot portfolio in the heart of Kendall Square. Kendall Square is considered to be among the largest and most important cluster of life sciences companies and research space in the United States. This property is 100% leased.
In October of 2022, we entered into an agreement to acquire Madison Centre, a Class A office propertyan approximate 27% interest in the Seattle, Washington central business district (“CBD”),joint venture that owns 200 Fifth Avenue, a 14-story, approximately 870,000 square-foot, LEED Gold certified, premier workplace located in New York City that is approximately 93% leased. The acquisition of the joint venture interest will be our second investment in the vibrant Midtown South neighborhood in the past twelve months. We will serve as the managing member and provide customary leasing and property management services for the joint venture. We expect to close the acquisition in the fourth quarter of 2022 for a gross purchase price of $730approximately $280.2 million, which includes $120.1 million of cash and our pro rata share of the outstanding loan secured by the property of $160.1 million. This addition to our portfolio furthers our goal to establish a strong platform for continued growthThe mortgage loan bears interest at 4.34% per annum and matures in the Seattle market. Built in 2017, Madison Centre is approximately 760,000 square feet, 37 floors, 93% leased and LEED Platinum certified. The acquisition is expected to close in the second quarter of this year andNovember 2028. There can be no assurance that we will be initially funded with a one-year, $730 million term loan. We anticipate ultimately fundingcomplete the acquisition through incremental asset sales, which we anticipate would be structured as like-kind exchangeson the terms currently contemplated or joint venture equity.
In the first quarter of 2022, we commenced two new development projects:
the redevelopment of 651 Gateway in South San Francisco, California, an office building that will be converted to approximately 327,000 net rentable square feet of life sciences space and that is owned by a joint venture in which we have a 50% interest; and
the development of the first phase of Platform 16 in San Jose, California, a Class A office project that is owned by a joint venture in which we have a 55% interest. The first phase is an approximately 390,000 net rentable square foot Class A creative office building. When all phases are complete, Platform 16 is expected to include approximately 1.1 million net rentable square feet.at all.
As of March 31,September 30, 2022, our development/redevelopment pipeline consists of 1114 properties that, when completed, we expect will total approximately 4.14.4 million net rentable square feet. Our share of the estimated total cost for these projects is approximately $2.9$2.7 billion, of which approximately $1.2 billion$948.2 million remained to be invested. The total development pipeline, inclusive of both office and lab/laboratory/life sciences developments, but excluding the View Boston Observatory at Thethe Prudential Center and Reston Next Residential, is 54% pre-leased as of April 29, 2022. The office development projects, which total approximately 2.8 million square feet, are approximately 57% pre-leased as of April 29, 2022, to predominately credit-strong clients with long-lease terms.52% pre-leased.
Supply-chain concerns and inflationary pressures continue to negatively impact our business and have been exacerbated by the war in Ukraine and the ongoing Omicron outbreak in China. Impacts on our business include increased time to complete construction projects and increased costs. Our construction schedule is one of the elements we consider when we evaluate bids for development projects and capital improvements. We have been successful in awarding bids and maintaining schedules through the pandemic. However, there are fewer choices for materials, and we continue to work closely with our consultants and contractors to ensure there are not items used in the development or redevelopment process that are not available or could, directly or indirectly, cause delays. We are intentionally minimizing the amount of materials we acquire from foreign suppliers, releasing material packages as early as possible and, when appropriate, purchasing materials in advance and storing them off-site. We currently expect to deliver all active developments and redevelopments on time and budget. However, we may experience greater costs and/or necessary materials may not be available, which could delay the completion of our development projects. A failure to deliver a project on time could expose us to additional costs, in time or penalties (including lease termination rights), under leases signed for the project.

At March 31,September 30, 2022 and 2021, we owned or had joint venture interests in a portfolio of 201193 and 196202 commercial real estate properties, respectively (in each case, the “Total Property Portfolio”). As a result of changes within our Total Property Portfolio, the financial data presented below shows significant changes in revenue and expenses from period-to-period. Accordingly, we do not believe that our period-to-period financial data with respect to the Total Property Portfolio is meaningful.provides a complete understanding of our operating results. Therefore, the comparison of operating results for the three and nine months ended March 31,September 30, 2022 and 2021 show separately the changes attributable to the properties that were owned by us and in-service throughout each period compared (the “Same Property Portfolio”) and the changes attributable to the properties included in the Acquired, Placed In-Service, Development or Redevelopment or Sold Portfolios.
In our analysis of operating results, particularly to make comparisons of net operating income between periods more 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 and in-service through the end of the latest period presented as our Same Property Portfolio. The Same Property Portfolio therefore excludes properties acquired, placed in-service or

NOINet operating income (“NOI”) is a non-GAAP financial measure equal to net income attributable to Boston Properties, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership common unitholders, as applicable, the most directly comparable GAAP financial measures, plus (1) preferred stock/unit redemption charge, preferred dividends/distributions, net income attributable to noncontrolling interests, interest expense, losses from early extinguishment of debt, loss from unconsolidated joint ventures, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts and corporate general and administrative expense less (2) gains (losses) from investments in securities, other income - assignment fee, interest and other income (loss), gains on sales of real estate, income from unconsolidated joint ventures, direct reimbursements of payroll and related costs from management services contracts and development and management services revenue. We use NOI internally as a performance measure and believe it provides useful information to investors regarding our results of operations and financial condition because, when compared across periods, it 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, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership common unitholders. 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. Similarly, interest expense may be incurred at the property level even though the financing proceeds may be used at the corporate level (e.g., used for other investment activity). In addition, depreciation and amortization expense, because of historical cost accounting and useful life estimates, may distort operating performance measures at the property level. NOI presented by us may not be comparable to NOI reported by other REITs or real estate companies that define NOI differently.
We believe that in order to facilitate a clear understanding ofunderstand our operating results, NOI should be examined in conjunction with net income attributable to Boston Properties, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership common unitholders as presented in our Consolidated Financial Statements. NOI should not be considered as a substitute for net income attributable to Boston Properties, Inc. common shareholders or net income attributable to Boston Properties Limited Partnership common unitholders (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to our financial information prepared in accordance with GAAP.
The gains on sales of real estate and depreciation expense and impairment losses may differ between BXP and BPLP as a result of previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor OP Unit redemptions by BPLP. This accounting resulted in a step-up of the real estate assets at BXP that was allocated to certain properties. The difference between the real estate assets of BXP as compared to BPLP for certain properties having an allocation of the real estate step-up will result in a corresponding difference in gains on sales of real estate and depreciation expense and impairment losses, when those properties are sold. For additional information see the Explanatory Note that follows the cover page of this Quarterly Report on Form 10-Q.
Comparison of the threenine months ended March 31,September 30, 2022 to the threenine months ended March 31,September 30, 2021
The table below shows selected operating information for the Same Property Portfolio and the Total Property Portfolio. The Same Property Portfolio consists of 140126 properties totaling approximately 39.638.2 million net rentable square feet, excluding unconsolidated joint ventures. The Same Property Portfolio includes properties acquired or placed in-service on or prior to January 1, 2021 and owned and in-servicein service through March 31,September 30, 2022. The Total Property Portfolio includes the effects of the other properties either acquired, placed in-service, in development or redevelopment after January 1, 2021 or disposed of on or prior to March 31,September 30, 2022. This table includes a reconciliation from the Same Property Portfolio to the Total Property Portfolio by also providing information for the threenine months ended March 31,September 30, 2022 and 2021 with respect to the properties that were acquired, placed in-service, in development or redevelopment or sold.

(1)Average Monthly Rental Rate is calculated as the average of the quotients obtained by dividing (A) rental revenue as determined in accordance with GAAP, by (B) the number of occupied units for each month within the applicable fiscal period.
(2)Average Physical Occupancy is defined as (1) the average number of occupied units divided by (2) the total number of units, expressed as a percentage.
(3)Average Economic Occupancy is defined as (1) total possible revenue less vacancy loss divided by (2) total possible revenue, expressed as a percentage. 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 used by us in calculating Economic Occupancy are based on the current market rates set by the managers of our residential properties based on their experience in renting their residential property’s units and publicly available market data. Actual market rents and trends in such rents for a region as reported by others may vary materially from Market Rents used by us. Market Rents for a period are based on the average Market Rents during that period and do not reflect any impact for cash concessions.

Concurrently with the sale, we agreed to act as development manager and guaranteed the completion of the project. The development project achieved final completion during the third quarter of 2021 at which time the total cost of development was determined to be below the estimated total investment at the time of sale. As a result, we recognized a gain of approximately $23.4 million related to the sale of 195 West Street in Waltham, Massachusetts (See Note 3 to the Consolidated Financial Statements).

Gains (Losses) from Investments in Securities
Gains (losses) from investments in securities for the threenine months ended March 31,September 30, 2022 and 2021 related to investments that we have made to reduce our market risk relating to deferred compensation plans that we maintain for BXP’s officers and former non-employee directors. Under the deferred compensation plans, each officer or non-employee director who is eligible to participate is permitted to defer a portion of the officer’s current income or the non-employee director’s compensation 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 or non-employee director. In order to reduce our market risk relating to these plans, 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 or non-employee director. This enables us to generally match our liabilities to BXP’s officers or former non-employee directors under our deferred compensation plans with equivalent assets and thereby limit our market risk. The performance of these investments is recorded as gains (losses) from investments in securities. During the threenine months ended March 31,September 30, 2022 and 2021, we recognized gains (losses) of approximately $(2.3)$(8.5) million and $1.7$3.7 million, respectively, on these investments. By comparison, our general and administrative expense increased (decreased) by approximately $(2.3)$(8.5) million and $1.7$3.7 million during the threenine months ended March 31,September 30, 2022 and 2021, respectively, as a result of increases (decreases) in our liability under our deferred compensation plans that was

Losses From Early Extinguishment of Debt
On February 14, 2021, BPLP completed the redemption of $850.0 million in aggregate principal amount of its 4.125% senior notes due May 15, 2021. The redemption price was approximately $858.7 million, which was equal to the stated principal plus approximately $8.7 million of accrued and unpaid interest to, but not including, the redemption date. Excluding the accrued and unpaid interest, the redemption price was equal to the principal amount being redeemed. We recognized a loss from early extinguishment of debt totaling approximately $0.4 million related to unamortized origination costs.
On March 16, 2021, BPLP repaid $500.0 million, representing all amounts outstanding on its delayed draw term loan facility (“Delayed Draw Facility”) under ourits prior unsecured revolving credit agreement (the “2017 Credit Facility”). We recognized a loss from early extinguishment of debt totaling approximately $0.5 million related to the acceleration of remaining unamortized financing costs.
Interest Expense
Interest expense decreased by approximately $6.7$2.8 million for the threenine months ended March 31,September 30, 2022 compared to 2021, as detailed below.

Interest expense directly related to the development of rental properties is capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over the useful lives of the real estate or lease term. As portions of properties are placed in-service, we cease capitalizing interest on that portion and interest is then expensed. Interest capitalized for the threenine months ended March 31,September 30, 2022 and 2021 was approximately $13.7$40.0 million and $12.0$39.3 million, respectively. These costs are not included in the interest expense referenced above.
We expect our interest expense will be materially greater in 2023 compared to 2022 due to the cessation of capitalized interest on our development deliveries, acquisitions funded by debt, higher interest rates on our floating rate debt, and the impact of refinancing our 2023 debt maturities at materially higher interest rates.

Noncontrolling Interest—Common Units of the Operating Partnership
For BXP, noncontrolling interest—common units of the Operating Partnership increased by approximately $5.3$47.4 million for the threenine months ended March 31,September 30, 2022 compared to 2021 due primarily to an increase in allocable income, which was partially the result of recognizing a greater gain on sales of real estate amount during 2022. Due to our ownership structure, there is no corresponding line item on BPLP’s financial statements.
Preferred Stock/Unit Redemption Charge
On March 2, 2021, BXP issued a redemption notice for 80,000 shares of its 5.25% Series B Cumulative Redeemable Preferred Stock, (the “Series B Preferred Stock”), which constituted all of the outstanding Series B Preferred Stock, and the corresponding depositary shares,Depositary Shares, each representing 1/100th of a share of Series B Preferred Stock. The redemption price per share of Series B Preferred Stock was $2,500, plus all accrued and unpaid dividendsdividend to, but not including, the redemption date, totaling $2,516.41 per share. On March 31, 2021, we transferred the full redemption price for all outstanding shares of Series B Preferred Stock of approximately, $201.3 million, including approximately $1.3 million of accrued and unpaid dividends to, but not including, the redemption date, to the redemption agent. The excess of the redemption price over the carrying value of the Series B Preferred Stock and Series B Preferred Units of approximately $6.4 million relates to the original issuance costs and is reflected as a reduction to Net Income Attributable to Boston Properties, Inc. common shareholders and Net Income Attributable to Boston Properties Limited Partnership common unitholders on the Consolidated Income Statement.

NOI is a non-GAAP financial measure equal to net income attributable to Boston Properties, Inc. and net income attributable to Boston Properties Limited Partnership, as applicable, the most directly comparable GAAP financial measures, plus (1) net income attributable to noncontrolling interests, interest expense, losses from investments in securities, loss from unconsolidated joint ventures, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts and corporate general and administrative expense less (2) interest and other income (loss), gains on sales of real estate, direct reimbursements of payroll and related costs from management services contracts and development and management services revenue. We use NOI internally as a performance measure and believe it provides useful information to investors regarding our results of operations and financial condition because, when compared across periods, it 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, Inc. and net income attributable to Boston Properties Limited Partnership. 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. Similarly, interest expense may be incurred at the property level even though the financing proceeds may be used at the corporate level (e.g., used for other investment activity). In addition, depreciation and amortization expense, because of historical cost accounting and useful life estimates, may distort operating performance measures at the property level. NOI presented by us may not be comparable to NOI reported by other REITs or real estate companies that define NOI differently.
We believe that in order to understand our operating results, NOI should be examined in conjunction with net income attributable to Boston Properties, Inc. and net income attributable to Boston Properties Limited Partnership as presented in our Consolidated Financial Statements. NOI should not be considered as a substitute for net

income attributable to Boston Properties, Inc. or net income attributable to Boston Properties Limited Partnership (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to our financial information prepared in accordance with GAAP.

Same Property Portfolio
Lease Revenue (Excluding Termination Income)
Lease revenue (excluding termination income) from the Same Property Portfolio increased by approximately $21.0 million for the three months ended September 30, 2022 compared to 2021. The increase was a result of our average revenue per square foot increasing by approximately $2.88, contributing approximately $25.4 million, partially offset by an approximately $4.4 million decrease due to our average occupancy decreasing from 91.4% to 90.8%.
Termination Income
Termination income decreased by approximately $0.2 million for the three months ended September 30, 2022 compared to 2021.
Termination income for the three months ended September 30, 2022 related to eight clients across the Same Property Portfolio and totaled approximately $1.7 million, which was primarily related to clients that terminated leases early in San Francisco.
Termination income for the three months ended September 30, 2021 related to six clients across the Same Property Portfolio and totaled approximately $1.9 million, which was primarily related to clients that terminated leases early in New York City.
Parking and Other Revenue
Parking and other revenue increased by approximately $3.5 million for the three months ended September 30, 2022 compared to 2021. Parking revenue increased by approximately $3.9 million and was partially offset by a decrease in other revenue of approximately $0.4 million. The increase in parking revenue was primarily due to an increase in transient and monthly parking.
Real Estate Operating Expenses
Real estate operating expenses from the Same Property Portfolio increased by approximately $17.8 million, or 7.3%, for the three months ended September 30, 2022 compared to 2021, due primarily to an increase in operating expenses, including cleaning, utilities, repairs and maintenance, and roads/grounds/security. The increase in operating expenses was driven by an increase in physical occupancy.

(1)Average Monthly Rental Rate is calculated as the average of the quotients obtained by dividing (A) rental revenue as determined in accordance with GAAP, by (B) the number of occupied units for each month within the applicable fiscal period.
(2)Average Physical Occupancy is defined as (1) the average number of occupied units divided by (2) the total number of units, expressed as a percentage.
(3)Average Economic Occupancy is defined as (1) total possible revenue less vacancy loss divided by (2) total possible revenue, expressed as a percentage. 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 used by us in calculating Economic Occupancy are based on the current market rates set by the managers of our residential properties based on their experience in renting their residential property’s units and publicly available market data. Actual market rents and trends in such rents for a region as reported by others may vary materially from Market Rents used by us. Market Rents for a period are based on the average Market Rents during that period and do not reflect any impact for cash concessions.

Other Operating Revenue and Expense Items
Development and Management Services Revenue
Development and management services revenue increased by approximately $1.4 million for the three months ended September 30, 2022 compared to 2021. Management services revenue increased by approximately $1.4 million and was primarily related to an increase in property management fees from an unconsolidated joint venture in the Boston region and asset management fees from an unconsolidated joint venture in the Los Angeles region.
General and Administrative Expense
General and administrative expense decreased by approximately $2.0 million for the three months ended September 30, 2022 compared to 2021 primarily due to a decrease in compensation expense of approximately $3.9 million, partially offset by an increase of approximately $1.9 million in other general and administrative expenses. The decrease in compensation expense primarily related to an approximately $1.4 million decrease in the value of

Table of Contents
our deferred compensation plan, and an approximately $2.5 million decrease in other compensation expenses. The increase in other general and administrative expenses was primarily related to an increase in professional fees.
Wages directly related to the development of rental properties are capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over the useful lives of the applicable asset or lease term. Capitalized wages for the three months ended September 30, 2022 and 2021 were approximately $3.9 million and $3.4 million, respectively. These costs are not included in the general and administrative expenses discussed above.
Transaction Costs
Transaction costs decreased by approximately $0.2 million for the three months ended September 30, 2022 compared to 2021 due primarily to costs incurred in connection with the pursuit and formation of new joint ventures. In general, transaction costs relating to the formation of new joint ventures and the pursuit of other transactions are expensed as incurred.
Depreciation and Amortization Expense
Depreciation expense may differ between BXP and BPLP as a result of previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor OP Unit redemptions by BPLP.  This accounting resulted in a step-up of the real estate assets at BXP that was allocated to certain properties.  The difference between the real estate assets of BXP as compared to BPLP for certain properties having an allocation of the real estate step-up will result in a corresponding difference in depreciation expense. For additional information see the Explanatory Note that follows the cover page of this Quarterly Report on Form 10-Q.

Direct Reimbursements of Payroll and Related Costs From Management Services Contracts and Payroll and Related Costs From Management Service Contracts
We have determined that amounts reimbursed for payroll and related costs received from third parties in connection with management services contracts should be reflected on a gross basis instead of on a net basis as we have determined that we are the principal under these arrangements. We anticipate that these two financial statement line items will generally offset each other.
Other Income and Expense Items
Loss from Unconsolidated Joint Ventures
For the three months ended September 30, 2022 compared to 2021, loss from unconsolidated joint ventures decreased by approximately $2.1 million due primarily to an approximately $2.2 million increase in net income from placing in service (1) 7750 Wisconsin Avenue (Marriott International Headquarters) in Bethesda, Maryland and (2) 100 Causeway Street in Boston, Massachusetts.
Gains on Sales of Real Estate
Gains on sales of real estate may differ between BXP and BPLP as a result of previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor OP Unit redemptions by BPLP. This accounting resulted in a step-up of the real estate assets at BXP that was allocated to certain properties. The difference between the real estate assets of BXP as compared to BPLP for certain properties having an allocation of the real estate step-up will result in a corresponding difference in the gains on sales of real estate when those properties are sold. For additional information, see the Explanatory Note that follows the cover page of this Quarterly Report on Form 10-Q.

Interest and Other Income (Loss)
Interest and other income (loss) increased by approximately $2.2 million for the three months ended September 30, 2022 compared to 2021, due primarily to an increase of approximately $2.2 million in interest income due to increased interest earned on our deposits.
Losses from Investments in Securities
Losses from investments in securities for the three months ended September 30, 2022 and 2021 related to investments that we have made to reduce our market risk relating to deferred compensation plans that we maintain for BXP’s officers and former non-employee directors. Under the deferred compensation plans, each officer or non-employee director who is eligible to participate is permitted to defer a portion of the officer’s current income or the non-employee director’s compensation 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 or non-employee director. In order to reduce our market risk relating to these plans, 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 or non-employee director. This enables us to generally match our liabilities to BXP’s officers or former non-employee directors under our deferred compensation plans with equivalent assets and thereby limit our market risk. The performance of these investments is recorded as losses from investments in securities. During the three months ended September 30, 2022 and 2021, we recognized losses of approximately $1.6 million and $0.2 million, respectively, on these investments. By comparison, our general and administrative expense decreased by approximately $1.6 million and $0.2 million during the three months ended September 30, 2022 and 2021, respectively, as a result of decreases in our liability under our deferred compensation plans that was associated with the performance of the specific investments selected by officers and former non-employee directors of BXP participating in the plans.
Interest Expense
Interest expense increased by approximately $6.1 million for the three months ended September 30, 2022 compared to 2021, as detailed below.

Interest expense directly related to the development of rental properties is capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over the useful lives of the real estate or lease term. As portions of properties are placed in-service, we cease capitalizing interest on that portion and interest is then expensed. Interest capitalized for the three months ended September 30, 2022 and 2021 was approximately $12.2 million and $14.2 million, respectively. These costs are not included in the interest expense referenced above.
At September 30, 2022, our outstanding variable rate debt consisted of BPLP’s $1.5 billion Revolving Facility and $730.0 million Unsecured Term Loan. The Revolving Facility and Unsecured Term Loan had approximately $1.1 billion outstanding as of September 30, 2022.

allocable income, which was the result of recognizing a greater gain on sales of real estate during 2022. Due to our ownership structure, there is no corresponding line item on BPLP’s financial statements.
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 the Unsecured Term Loan and balloon payments on maturing debt;
fund development and redevelopment costs;
fund capital expenditures, including major renovations, tenant improvements and leasing costs;
fund pending and possible acquisitions of properties, either directly or indirectly through the acquisition of equity interests therein; and
make the minimum distribution required to enable BXP 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;
borrowings under BPLP’s Revolving Facility, unsecured term loans, short-term bridge facilities and construction loans;
long-term secured and unsecured indebtedness (including unsecured exchangeable indebtedness);
sales of real estate;
private equity sources including through our Strategic Capital Program (“SCP”) with large institutional investors; and
issuances of BXP equity securities and/or preferred or common units of partnership interests in BPLP.
We draw on multiple financing sources to fund our long-term capital needs. We expect to fund our current development/redevelopment properties primarily with our available cash balances, construction loans, unsecured term loans, proceeds from asset sales and BPLP’s Revolving Facility. We use BPLP’s Revolving Facility primarily as a bridge facility to fund acquisition opportunities, refinance outstanding indebtedness and meet short-term development and working capital needs. Although we may seek to fund our development projects with construction loans, which may require guarantees by BPLP, the financing for each particular project ultimately depends on several factors, including, among others, the project’s size and duration, the extent of pre-leasing, and our available cash and access to cost effective capital at the given time.

Lease revenue (which includes recoveries from tenants)clients), other income from operations, available cash balances, mortgage financings, unsecured indebtedness and draws on BPLP’s Revolving Facility are the principal sources of capital that we use to fund operating expenses, debt service, maintenance and repositioning capital expenditures, tenant improvements and the minimum distribution required to enable BXP 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 tenantclient turnover and controlling operating expenses. Our sources of revenue also include third-party fees generated by our property management, leasing, development and construction businesses, as well as the sale of assets from time to time. We believe these sources of capital will continue to provide the funds necessary for our short-term liquidity needs, including our properties under development and redevelopment.needs. Material adverse changes in one or more sources of capital whether due to the impacts of the COVID-19 pandemic or otherwise, may adversely affect our net cash flows.
We expect our primary uses of capital over the next twelve months will be to fund the anticipated acquisition of an approximate 27% interest in the joint venture that owns 200 Fifth Avenue in New York City, the commencement, continuation and completion of our current and committed development and redevelopment projects, the acquisition of Madison Centre,repaying debt maturities (as discussed below), servicing the interest payments on our outstanding indebtedness, and satisfying our REIT distribution requirements.
As of March 31,September 30, 2022, we had 1114 properties under development or redevelopment. Our share of the remaining development and redevelopment costs of active development and redevelopment projects that we expect to fund through 2026 was approximately $1.2 billion.$948.2 million (excluding costs related to 300 Binney Street). In Januarythe third quarter of 2022, we commenced two redevelopment projects and committed to begin a third redevelopment project in early 2023 described below:
140 Kendrick Street Building A in Needham, Massachusetts. When completed, the building will consist of approximately 104,000 net rentable square feet and will be the first net zero, carbon neutral office repositioning of this scale in Massachusetts. This project is 100% pre-leased.
760 Boylston Street, a retail property at the Prudential Center in Boston, Massachusetts. The redevelopment is a modernization of the approximately 118,000 net rentable square foot space. This project is 100% pre-leased.
300 Binney Street in Cambridge, Massachusetts. The conversion of this approximately 195,000 net rentable square foot property into an approximately 240,000 net rentable square foot laboratory/life sciences property has a total budgeted cost of $210.0 million and is expected to begin in early 2023. This project is 100% pre-leased. There can be no assurance that we will commence the redevelopment of 651 Gateway in South San Francisco, California, a project in which we own a 50% interest,on the terms and in Februaryschedule currently contemplated or at all.
On September 16, 2022, we restartedacquired 125 Broadway in Cambridge, Massachusetts for a net purchase price, including transaction costs, of approximately $592.4 million. The acquisition was completed with available cash and borrowings under BPLP’s Revolving Facility. 125 Broadway is a 271,000 square foot, six-story, laboratory/life sciences property. The property is 100% leased.
In the first phasethird quarter of our Platform 16 development project2022, we completed the sale of 601 Massachusetts Avenue located in San Jose, California,Washington, DC and two parcels of land located in Loudoun County, Virginia for aggregate net proceeds of $537.9 million. On October 6, 2022, we entered into an agreement to sell the residential component of The Avant at Reston Town Center located in Reston, Virginia for a project in whichgross sale price of $141 million. There can be no assurance that we own a 55% interest (see Note 5 towill complete the Consolidated Financial Statements).sale on the terms currently contemplated or at all.
In July 2021, we announced the formation of an investment programthe SCP with two partners committingeach having a targeted equity investmentcommitment of $1.0 billion includingand a $250 million commitment from us. Under this agreement, we willagreed to provide these partners, for up to two years, exclusive first offers to form joint ventures with us to invest in assets that meet target criteria. All investments are discretionary to each partner.
The SCP provides us the opportunity to partner with large institutional investors and capitalize our investment opportunities partially through private equity. The SCP enhances our access to capital and investment capacity, and further enhances our returns through fee income, and in certain partnerships,some investments provides us the opportunity to realize a greater share of income upon achieving certain success criteria. These large financial partners include some ofare among the world’s largest sovereign wealth funds and pension plans. OurAs we move forward, we anticipate increasing our use of the SCP is consistent with our ongoing strategy to create value through opportunistic investments in high-quality office properties in markets with the strongest economic growth over time while maintaining a strong balance sheet and modest leverage.
On April 14, 2022, we entered into an agreement to purchase Madison Centre, an approximately 760,000 square foot, 37-story Class A office building in Seattle, Washington for a gross purchase price of $730.0 million. The acquisition is expected to close in the second quarter of this year and will be initially funded with a one-year, $730.0 million unsecured term loan. We anticipate ultimately funding the acquisition through incremental asset sales, which we anticipate would be structured as like-kind exchanges, or joint venture equity.partner equity to manage our debt levels.

We have no remaining debt maturities untilin 2022. Our 2023 debt maturities include (1) the Unsecured Term Loan, which matures on May 16, 2023, and (2) $500.0 million aggregate principal amount of BPLP’s 3.125% senior unsecured notes, which mature on September 1, 2023. OurIn our unconsolidated joint venturesventure portfolio, we have one loan maturingapproximately $533.6 million (our share) of debt maturating in 2023. We expect to fund 2023 debt maturities using available cash balances, proceeds from asset sales, BPLP’s Revolving Facility, and/or through refinancings. We expect our interest expense will be materially greater in 2023 compared to 2022 due to the cessation of whichcapitalized interest on our sharedevelopment deliveries, acquisitions funded by debt, higher interest rates on our floating rate debt, and the impact of the aggregate outstanding principal is approximately $88.2 million. We are currently in the market to refinance this maturity with a mortgagerefinancing our 2023 debt in an amount equal to or greater than the current balance. There can be no assurance that we will complete this refinancing on the terms currently contemplated ormaturities at all.materially higher interest rates.
As of April 25,November 1, 2022, we had available cash of approximately $313.8$268.5 million (of which approximately $103.8$100.3 million is attributable to our consolidated joint venture partners). Although the future impact of COVID-19 on ourOur liquidity and capital resources will depend on a wide range of factors and we believe that our access to capital and our strong liquidity, including the approximately $1.3$1.1 billion available under the Revolving Facility and our available cash, as of April 25,November 1, 2022, are sufficient to fund our remaining capital requirements on existing development and redevelopment projects, fund acquisitions, repay or refinance our maturing indebtedness when due, satisfy our REIT distribution requirements and still allow us to act opportunistically on attractive investment opportunities.

Table of Contents
We may seek to enhance our liquidity to fund our current and future development activity, pursue additional attractive investment opportunities and refinance or repay indebtedness. Depending on interest rates, the overall conditions in the debt and public and private equity markets, and our leverage at the time, we may decide to access one or more of these capital sources (including utilization of BXP’s $600.0 million “at the market” equity offering program). Doing so may result in us carrying additional cash and cash equivalents pending our use of the proceeds, which could increase our net interest expense or be dilutive to our earnings, or both.
We have not sold any shares under BXP’s $600.0 million “at the market” equity offering program.
REIT Tax Distribution Considerations
Dividend
BXP as a REIT is subject to a number of organizational and operational requirements, including a requirement that BXP currently distribute at least 90% of its annual taxable income (excluding capital gains and with certain other adjustments). Our policy is for BXP to distribute at least 100% of its taxable income, including capital gains, to avoid paying federal tax. Common and LTIP unitholders (other than unearned MYLTIP units) of limited partnership interest in BPLP receive the same total distribution per unit.
BXP’s Board of Directors will continue to evaluate BXP’s dividend rate in light of our actual and projected taxable income (including gains on sales), liquidity requirements and other circumstances and there can be no assurance that the future dividends declared by BXP’s Board of Directors will not differ materially from the current quarterly dividend amount.
Sales
To the extent that we sell assets at a gain and cannot efficiently use the proceeds in a tax deferred manner for either our development activities or attractive acquisitions, BXP would, at the appropriate time, decide whether it is better to declare a special dividend, adopt a stock repurchase program, reduce 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 BXP’s common stock and REIT distribution requirements. At a minimum, we expect that BXP would distribute at least that amount of proceeds necessary for BXP to avoid paying corporate level tax on the applicable gains realized from any asset sales.
From time to time in select cases, whether due to a change in use, structuring issues to comply with applicable REIT regulations or other reasons, we may sell an asset that is held by a taxable REIT subsidiary (“TRS”). Such a sale by a TRS would be subject to federal and local taxes.

Consolidated Debt to Consolidated Market Capitalization Ratio is a measure of leverage commonly used by analysts in the REIT sector. We present this measure as a percentage and it is calculated by dividing (A) our consolidated debt by (B) our consolidated market capitalization, which is the market value of our outstanding equity securities plus our consolidated debt. Consolidated market capitalization is the sum of:
85

Table of Contents
(1)     our consolidated debt; plus
(2)     the product of (x) the closing price per share of BXP Common Stock on March 31,September 30, 2022, as reported by the New York Stock Exchange, multiplied by (y) the sum of:
(i)     the number of outstanding shares of Common Stock of BXP,
(ii)     the number of outstanding OP Units in BPLP (excluding OP Units held by BXP),
59

Table of Contents
(iii)     the number of OP Units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units, and
(iv)     the number of OP Units issuable upon conversion of 2012 OPP Units, and 2013 - 2019 MYLTIP Units that were issued in the form of LTIP Units.
The calculation of consolidated market capitalization does not include LTIP Units issued in the form of MYLTIP Awards unless and until certain performance thresholds are achieved and they are earned. Because their three-year performance periods have not yet ended, 2020 - 2022 MYLTIP Units are not included in this calculation as of March 31,September 30, 2022.
We also present BXP’s Share of Market Capitalization and BXP’s Share of Debt/BXP’s Share of Market Capitalization, which are calculated in the same manner, except that BXP’s Share of Debt is utilized instead of our consolidated debt in both the numerator and the denominator. BXP’s Share of Debt is defined as our consolidated debt plus our share of debt from our unconsolidated joint ventures (calculated based upon our ownership percentage), minus our partners’ share of debt from our consolidated joint ventures (calculated based upon the partners’ percentage ownership interests adjusted for basis differentials). Management believes that BXP’s Share of Debt provides useful information to investors regarding our financial condition because it includes our share of debt from unconsolidated joint ventures and excludes our partners’ share of debt from consolidated joint ventures, in each case presented on the same basis. We have several significant joint ventures and presenting various measures of financial condition in this manner can help investors better understand our financial condition and/or results of operations after taking into account our economic interest in these joint ventures.  We caution investors that the ownership percentages used in calculating BXP’s Share of Debt may not completely and accurately depict all of the legal and economic implications of holding an interest in a consolidated or unconsolidated joint venture. For example, in addition to partners’ interests in profits and capital, venture agreements vary in the allocation of rights regarding decision making (both for routine and major decisions), distributions, transferability of interests, financing and guarantees, liquidations and other matters.  Moreover, in some cases we exercise significant influence over, but do not control, the joint venture in which case GAAP requires that we account for the joint venture entity using the equity method of accounting and we do not consolidate it for financial reporting purposes. In other cases, GAAP requires that we consolidate the venture even though our partner(s) own(s) a significant percentage interest.  As a result, management believes that the presentation of BXP’s Share of a financial measure should not be considered a substitute for, and should only be considered with and as a supplement to our financial information presented in accordance with GAAP.
We present these supplemental ratios 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 and because different investors and lenders consider one or both of these ratios. Investors should understand that these ratios are, in part, a function of the market price of the common stock of BXP and as such will fluctuate with changes in such price, and they do 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 BXP, whose assets are primarily income-producing real estate, these ratios may provide investors with an alternate indication of leverage, so long as they are 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.
For a discussion of our unconsolidated joint venture indebtedness, see “Liquidity and Capital Resources—Investment in Unconsolidated Joint Ventures - Secured DebtDebt” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations” and for a discussion of our consolidated joint venture indebtedness see “Liquidity and Capital Resources—Mortgage Notes Payable” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Investment in Unconsolidated Joint Ventures - Secured Debt
We have investments in unconsolidated joint ventures with our effective ownership interests ranging from 20% to 55%. FifteenSixteen of these ventures have mortgage indebtedness. We exercise significant influence over, but do not control, these entities. As a result, we account for them using the equity method of accounting. See also Note 5 to the Consolidated Financial Statements. At March 31,September 30, 2022, the aggregate carrying amount of debt, including both our and our partners’ share, incurred by these ventures was approximately $3.4 billion (of which our proportionate share is approximately $1.4$1.5 billion). The table below summarizes the outstanding debt of these joint venture properties at March 31,September 30, 2022. 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) as well as the completion of development projects on certain of the loans.

State and Local Tax Matters 
Because BXP is organized and qualifies as a REIT, it is generally not subject to federal income taxes, but is 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 position 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
For information concerning our insurance program, see Note 67 to the Consolidated Financial Statements.
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,” for each of BXP and BPLP by adjusting net income (loss) attributable to Boston Properties, Inc. common shareholders and net income (loss) attributable to Boston Properties Limited Partnership common unitholders (computed in accordance with GAAP), respectively, for gains (or losses) from sales of properties, impairment losses on depreciable real estate consolidated on our balance sheet, impairment losses on our investments in unconsolidated joint ventures driven by a measurable decrease in
6491

Table of Contents
driven by a measurable decrease in the fair value of depreciable real estate held by the unconsolidated joint ventures and our share of real estate-related depreciation and amortization. FFO is a non-GAAP financial measure. We believe the presentation of FFO, combined with the presentation of required GAAP financial measures, improves the understanding of operating results of REITs among the investing public and helps make comparisons of REIT operating results more meaningful. Management generally considers FFO to be useful measures for understanding and comparing our operating results because, by excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment losses and real estate asset depreciation and amortization (which can differ across owners of similar assets in similar condition based on historical cost accounting and useful life estimates), FFO can help investors compare the operating performance of a company’s real estate across reporting periods and to the operating performance of other 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. We believe that in order to facilitate a clear understanding of our operating results, FFO should be examined in conjunction with net income attributable to Boston Properties, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership as presented in our Consolidated Financial Statements. FFO should not be considered as a substitute for net income attributable to Boston Properties, Inc. common shareholders or net income attributable to Boston Properties Limited Partnership common unitholders (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to our financial information prepared in accordance with GAAP.

Material Cash Commitments
On April 14, 2022, we entered into an agreement to purchase Madison Centre, an approximately 760,000 square foot, 37-story Class A office building in Seattle, Washington for a gross purchase price of $730.0 million. The acquisition is expected to close in the second quarter of this year and will be initially funded with a one-year, $730.0 million unsecured term loan. We anticipate ultimately funding the acquisition through incremental asset sales, which we anticipate would be structured as like-kind exchanges, or joint venture equity.
We have various service contracts with vendors related to our property management. In addition, we have certain other contracts we enter into in the ordinary course of business that may extend beyond one year. These contracts include terms that provide for cancellation with insignificant or no cancellation penalties. Contract terms are generally between three and five years.
During the three months ended March 31,September 30, 2022, we paid approximately $70.1$60.1 million to fund tenant-relatedclient-related obligations, including tenant improvements and leasing commissions.
In addition, during the three months ended March 31,September 30, 2022, we and our unconsolidated joint venture partners incurred approximately $90.8$100.3 million of new tenant-relatedclient-related obligations associated with approximately 1.21.0 million square feet of second generation leases, or approximately $79$99 per square foot. We signed approximately 21,000429,900 square feet of first generation leases. The tenant-relatedclient-related obligations for the development properties are included within the projects’ “Estimated Total Investment” referred to in “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.” In aggregate during the firstthird quarter of 2022, we signed leases for approximately 1.21.4 million square feet of space and incurred aggregate tenant-relatedclient-related obligations of approximately $94.9$198.9 million, or approximately $80$137 per square foot.

As of March 31,September 30, 2022, approximately $12.8 billion of these borrowings bore interest at fixed rates and therefore the fair value of these instruments is affected by changes in the market interest rates. As of March 31,September 30, 2022, the weighted-average interest rate on our variable rate debt was LIBOR plus 0.775% (1.02%)3.40% per annum.

At March 31,September 30, 2022, the weighted-average coupon/stated rates on the fixed rate debt stated above was 3.32% per annum. At March 31,September 30, 2022, our outstanding variable rate debt based on LIBOR totaled
approximately $255.0$340.0 million and our outstanding variable rate debt based on SOFR totaled $730.0 million. At March 31,September 30, 2022, the coupon/stated rate on our variable rate debt was
approximately 1.02%3.40% per annum. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $0.6$2.7 million and $8.0 million for the three and nine months ended March 31, 2022.September 30, 2022, respectively.
The fair value 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.
On March 5, 2021, the Financial Conduct Authority (“FCA”) announced that USD LIBOR will no longer be published after June 30, 2023. This announcement has several implications, including setting the spread that may be used to automatically convert contracts from LIBOR to the Secured Overnight Financing Rate (“SOFR”).SOFR. Additionally, banking regulators are encouraging banks to discontinue new LIBOR debt issuances by December 31, 2021.
We anticipate that LIBOR will continue to be available at least until June 30, 2023. Any changes adopted by the FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in its current form.
We and our unconsolidated joint ventures have contracts that are indexed to LIBOR and we are monitoring and evaluating the related risks. These risks arise in connection with transitioning contracts to an alternative rate, including any resulting value transfer that may occur, and are likely to vary by contract. The value of loans, securities, or derivative instruments tied to LIBOR, as well as interest rates on our unconsolidated joint ventures current or future indebtedness, may also be impacted if LIBOR is limited or discontinued. For some instruments the

method of transitioning to an alternative reference rate may be challenging, especially if we cannot agree with the respective counterparty about how to make the transition.

Table of Contents
While we expect LIBOR to be available in substantially its current form until at least the end of June 30, 2023, it is possible that LIBOR will become unavailable prior to that point. This could result, for example, if a sufficient number of banks decline to make submissions to the LIBOR administrator. In that case, the risks associated with the transition to an alternative reference rate will be accelerated and magnified.
Alternative rates and other market changes related to the replacement of LIBOR, including the introduction of financial products and changes in market practices, may lead to risk modeling and valuation challenges, such as adjusting interest rate accrual calculations and building a term structure for an alternative rate.
The introduction of an alternative rate also may create additional basis risk and increased volatility as alternative rates are phased in and utilized in parallel with LIBOR.
Adjustments to systems and mathematical models to properly process and account for alternative rates will be required, which may strain the model risk management and information technology functions and result in substantial incremental costs for us.

PART II. OTHER INFORMATION
ITEM 1—Legal Proceedings.
We are subject to legal proceedings and claims that arise in the ordinary course of business. These matters are generally covered by insurance. Management believes that the final outcome of such matters will not have a material adverse effect on our financial position, results of operations or liquidity.
ITEM 1A—Risk Factors.
Except to the extent updated below 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, 2021.
Enhanced market and economic volatility due to adverse economic and geopolitical conditions, such as the war in Ukraine, health crises or dislocations in the credit markets, could have a material adverse effect on our results of operations, financial condition and ability to pay dividends and/or distributions.
Our business may be adversely affected by market and economic volatility experienced by the U.S. and global economies, the real estate industry as a whole and/or the local economies in the markets in which our properties are located, Such adverse economic and geopolitical conditions may be due to, among other issues, increased labor market challenges impacting the recruitment and retention of talent,employees, rising inflation and interest rates, volatility in the public equity and debt markets, and international economic and other conditions, including pandemics, geopolitical instability (such as the war in Ukraine), sanctions and other conditions beyond our control. These current conditions, or similar conditions existing in the future, may adversely affect our results of operations, financial condition and ability to pay dividends and/or distributions as a result of one or more of the following, among other potential consequences:
the financial condition of our tenantsclients may be adversely affected, which may result in tenantclient defaults under leases due to bankruptcy, lack of liquidity, lack of funding, operational failures or for other reasons;
significant job losses may occur, which may decrease demand for our office space, causing market rental rates and property values to be negatively impacted;
tightening labor market conditions may adversely affect our ability to recruit and retain talent, which may result in lack of business continuity and increased costs to address the labor challenges;
our ability to borrow on terms and conditions that we find acceptable, or at all, may be limited, which could reduce our ability to pursue acquisition and development opportunities and refinance existing debt, reduce our returns from our acquisition and development activities and increase our future interest expense;
reduced values of our properties may limit our ability to dispose of assets at attractive prices or to obtain debt financing secured by our properties and may reduce the availability of unsecured loans;
the value and liquidity of our short-term investments and cash deposits could be reduced as a result of a deterioration of the financial condition of the institutions that hold our cash deposits or the institutions or assets in which we have made short-term investments, a dislocation of the markets for our short-term investments, increased volatility in market rates for such investments or other factors;
one or more lenders under our line of credit could refuse to fund their financing commitment to us or could fail and we may not be able to replace the financing commitment of any such lenders on favorable terms, or at all; and
to the extent we enter into derivative financial instruments, one or more counterparties to our derivative financial instruments could default on their obligations to us, or could fail, increasing the risk that we may not realize the benefits of these instruments.
