EXPLANATORY NOTE
This report combines the Quarterly Reports on Form 10-Q for the period ended September 30, 2021March 31, 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 September 30, 2021,March 31, 2022, BXP owned an approximate 89.9%89.6% ownership interest in BPLP. The remaining approximate 10.1%10.4% interest was owned by limited partners. The other limited partners of BPLP areeither (1) persons who contributed their direct or indirect interests in properties to BPLP in exchange for common units or preferred units of limited partnership interest in BPLP and/or (2) recipients ofreceived long-term incentive plan units of BPLP pursuant to BXP’s Stock Option and Incentive Plans.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 offeringsissuances 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.
Equity,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


Table of Contents
noncontrolling interests in BPLP and limited partners of BPLP. The differences between shareholders’ equity and partners’ capital result from differences in the equity issued at BXP and BPLP levels.
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. This resultedredemptions, resulting in a difference between the net real estate of BXP as compared to BPLP of approximately $264.7$259.0 million, or 1.5%1.4% at September 30, 2021,March 31, 2022, and a corresponding difference in depreciation expense, impairment losses and gains on sales of real estate upon the sale of certainthese 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 futuresubsequent redemptions to be accounted for solely as an equity transaction.
To help investors better understand the key differences between BXP and BPLP, certainthe following items in this report present information separately for BXP and BPLP in this report has been separated, as set forth below:BPLP:

BOSTON PROPERTIES, INC. AND BOSTON PROPERTIES LIMITED PARTNERSHIP
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
1. Organization
Boston Properties, Inc., a Delaware corporation,BXP is a fully integrated, self-administered and self-managed real estate investment trust (“REIT”). Boston Properties, Inc.REIT. BXP is the sole general partner of Boston Properties Limited Partnership,BPLP, its operating partnership, and at September 30, 2021March 31, 2022 owned an approximate 89.9% (90.0%89.6% (89.7% at December 31, 2020)2021) general and limited partnership interest in Boston Properties Limited Partnership.BPLP. Unless stated otherwise or the context requires, the “Company” refers to Boston Properties, Inc.BXP and its subsidiaries, including Boston Properties Limited PartnershipBPLP and its consolidated subsidiaries. Partnership interests in Boston Properties Limited PartnershipBPLP 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”), and
preferred units of partnership interest (also referred to as “Preferred Units”).
Unless specifically noted otherwise, all references to OP Units exclude units held by Boston Properties, Inc.BXP. A holder of an OP Unit may present suchthe OP Unit to Boston Properties Limited PartnershipBPLP 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 1 year from issuance). Upon presentation of an OP Unit for redemption, Boston Properties Limited PartnershipBPLP is obligated to redeem the OP Unit for cash equal to the value of a share of common stock of Boston Properties, Inc.BXP (“Common Stock”). In lieu of asuch cash redemption, Boston Properties, Inc.BXP may elect to acquire the OP Unit for 1 share of Common Stock. Because the number of shares of Common Stock outstanding at all times equals the number of OP Units that Boston Properties, Inc.BXP owns, 1 share of Common Stock is generally the economic equivalent of 1 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 - 20212022 multi-year, long-term incentive program awards (also referred to as “MYLTIP Units”), each of which, upon the satisfaction of certain performance and vesting conditions, is convertible into one OP Unit. The three-year measurement periods for the 2012 OPP Units and the 2013 - 20182019 MYLTIP Units have ended and Boston Properties, Inc.’sBXP’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 20192020 - 20212022 MYLTIP Units differ from other LTIP Units granted to employees (including the 2012 OPP Units and the 2013 - 20182019 MYLTIP Units, which have been earned). Therefore, unless specifically noted otherwise, all references to LTIP Units exclude the 20192020 - 20212022 MYLTIP Units. LTIP Units (including the earned 2012 OPP Units and the earned 2013 - 20182019 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 107 and 14).
At December 31, 2020, there was 1 series of Preferred Units outstanding (i.e., Series B Preferred Units). The Series B Preferred Units were issued to Boston Properties, Inc. on March 27, 2013 in connection with the issuance of 80,000 shares (8,000,000 depositary shares each representing 1/100th of a share) of 5.25% Series B Cumulative Redeemable Preferred Stock (the “Series B Preferred Stock”). Boston Properties, Inc. contributed the net proceeds from the offering to Boston Properties Limited Partnership in exchange for 80,000 Series B Preferred Units having terms and preferences generally mirroring those of the Series B Preferred Stock. On March 2, 2021, Boston Properties, Inc. issued a redemption notice for 80,000 shares of 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 “Depositary Shares”), and recorded it as a liability. On March 31, 2021, Boston Properties, Inc. 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. On April 1, 2021, Boston Properties, Inc. redeemed 80,000 shares of Series B Preferred Stock (including the corresponding 8,000,000 Depositary Shares), which represented all of the outstanding shares of Series B Preferred Stock and all of the outstanding Depositary Shares. In connection with the redemption of the Series B Preferred Stock, the Series B Preferred Units were also redeemed (See Note 11).

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.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, 2020.2021.
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 6 of the 7 entities that are VIEs.
Consolidated Variable Interest Entities
As of September 30, 2021, Boston Properties, Inc.March 31, 2022, BXP has identified 6 consolidated VIEs, including Boston Properties Limited Partnership.BPLP.

Table of Contents
The Company consolidates these VIEs because it is the primary beneficiary.  The third parties’ interests in these consolidated entities (excluding Boston Properties Limited Partnership’sBPLP’s interest) are reflected as noncontrolling interests in property partnerships in the accompanying consolidated financial statements (See Note 10)7).
In addition, Boston Properties, Inc.’sBXP’s only significant asset is its investment in Boston Properties Limited PartnershipBPLP and, consequently, substantially all of Boston Properties, Inc.’sBXP’s assets and liabilities are the assets and liabilities of Boston Properties Limited Partnership.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.

The Company must make estimates as to the collectability of its accrued rent and accounts receivable balances related to lease revenue. When evaluating the collectability of tenants’ accrued rent and accounts receivable balances, management considers tenant creditworthiness, current economic trends, including the impact of COVID-19 on tenants’ businesses, and changes in tenants’ payment patterns, on a lease-by-lease basis. As a result, during thenine months ended September 30, 2021, the Company wrote off approximately $1.3 million related to accrued rent, net balances and accounts receivable, net balances. There were no new write-offs related to accrued rent, net balances and accounts receivable, net balances for the three months ended September 30, 2021.March 31, 2022. However, during the three months ended March 31, 2022, the Company determined it was probable of collecting substantially all of certain tenants’ accrued rent and account receivable balances and, therefore, ceased recognizing revenue from such tenants on a cash basis. As a result of returning these tenants to accrual basis accounting, the Company reinstated approximately $1.0 million of accrued rent balances. During the three and nine months ended September 30, 2020,March 31, 2021, the Company wrote off approximately $7.5$0.4 million and $63.8 million, respectively, related to accrued rent, net balances and accounts receivable, net balances. The write-offs were for tenants, primarily in the retail sector, that either terminated their leases or for which the Company determined their accrued rent and/or accounts receivable balances were no longer probable of collection.

Insurance
The Company’s property insurance program per occurrence limits are $1.0 billion for its portfolio insurance program, including coverage for acts of terrorism other than nuclear, biological, chemical or radiological terrorism (“Terrorism Coverage”). The Company also carries $250 million$1.35 billion of Terrorism Coverageproperty insurance in excess of the $1.0 billion of coverage in the Company’s property insurance program for 601 Lexington Avenue, New York, New York, (“601 Lexington Avenue”)consisting of $750 million of property and Terrorism Coverage in excess of the $1.0 billionof coverage in the Company’s property insurance program.program and $600 million of Terrorism Coverage only in excess of the $1.75 billion of coverage. Certain properties, including the General Motors Building located at 767 Fifth Avenue in New York, New York (“767 Fifth Avenue”), are currently insured in separate insurance programs. The property insurance program per occurrence limits for 767 Fifth Avenue are $1.625 billion, including Terrorism Coverage. The Company also currently carries nuclear, biological, chemical and radiological terrorism insurance coverage for acts of terrorism certified under the Federal Terrorism Risk Insurance Act (as amended, “TRIA”) (“NBCR Coverage”), which is provided by IXP as a direct insurer, for the properties in the Company’s portfolio, including 767 Fifth Avenue, but excluding certain other properties owned in joint ventures with third parties or which the Company manages. The per occurrence limit for NBCR Coverage is $1.0 billion. Under TRIA, after the payment of the required deductible and coinsurance, the NBCR Coverage provided by IXP is backstopped by the Federal Government if the aggregate industry insured losses resulting from a certified act of terrorism exceed a “program trigger.” The program trigger is $200 million, the coinsurance is 20% and the deductible is 20% of the premiums earned by the insurer for the year prior to a claim. If the Federal Government pays out for a loss under TRIA, it is mandatory that the Federal Government recoup the full amount of the loss from insurers offering TRIA coverage after the payment of the loss pursuant to a formula in TRIA. The Company may elect to terminate the NBCR Coverage if the Federal Government seeks recoupment for losses paid under TRIA, if TRIA is not extended after its expiration on December 31, 2027, if there is a change in its portfolio or for any other reason. The Company intends to continue to monitor the scope, nature and cost of available terrorism insurance.
The Company also currently carries earthquake insurance on its properties located in areas known to be subject to earthquakes. Specifically, the Company currently carries earthquake insurance which covers its San Francisco and Los Angeles regions with a $240$330 million per occurrence limit, and a $240$330 million annual aggregate limit, $20$30 million of which is provided by IXP, as a direct insurer. This insurance is subject to a deductible in the amount of 3% of the value of the affected property. In addition, the Company currently carries earthquake insurance which covers its Seattle region with a $60 million per occurrence limit, and a $60 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.

Table of Contents
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, Boston Properties Limited PartnershipBPLP has issued a guarantee to cover liabilities of IXP in the amount of $20.0 million.
Due to the current COVID-19 pandemic, the Company anticipates the possibility of business interruption, loss of lease revenue and/or other associated expenses related to the Company’s operations across its portfolio. Because this is an ongoing situation it is not yet possible to quantify the Company’s losses and expenses, which continue to develop. Because of the complexity of the Company’s insurance policies and limited precedent for claims being made related to pandemics, it is not yet possible to determine if such losses and expenses will be covered by the Company’s insurance policies. Therefore, at this time, the Company has provided notice to the applicable insurers of potential for claims in order to protect the Company’s rights under its policies.
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.

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, interest and other income (loss), gains (losses) 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 property level. NOI

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), minus 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 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 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, interest and other income (loss), gains (losses) 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.

13.10. Earnings Per Share / Common Unit
Boston Properties, Inc.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 Boston Properties, Inc.BXP and Boston Properties Limited Partnership’sBPLP’s LTIP Units, 2012 OPP Units and MYLTIP Units are considered participating securities. Participating securities are included in the computation of basic EPS of Boston Properties, Inc.BXP using the two-class method. Participating securities are included in the computation of diluted EPS of Boston Properties, Inc.BXP using the if-converted method if the impact is dilutive. Because the 2012 OPP Units and 2013 - 20182019 MYLTIP Units required, and the 20192020 - 20212022 MYLTIP Units require, Boston Properties, Inc.BXP to outperform absolute and/or relative return thresholds, unless such thresholds have been met by the end of the applicable reporting period, Boston Properties, Inc.BXP excludes such units from the diluted EPS calculation. Other potentially dilutive common shares, including stock options, restricted stock and other securities of Boston Properties Limited PartnershipBPLP that are exchangeable for Boston Properties, Inc.’sBXP’s Common Stock, and the related impact on earnings, are considered when calculating diluted EPS.

14.11. Stock Option and Incentive Plan
On February 2, 2021, Boston Properties, Inc.’s1, 2022, BXP’s Compensation Committee approved the 20212022 MYLTIP awards under the Boston Properties, Inc. 20122021 Stock Option and Incentive Plan (the “2012“2021 Plan”) to certain officers and employees of Boston Properties, Inc.BXP. The 20212022 MYLTIP awards consist of two, equally weighted (50% each) components that utilize Boston Properties, Inc.’sBXP’s TSR over a three-year measurement period as the performance metric.
The first component of the 20212022 MYLTIP which represents one-half (50%) of the target grant-date value retains the basic general structure of the 2020 MYLTIP awards with certain changes, including a change to the

Table of Contents
custom peer index against which Boston Properties, Inc.’s TSR is compared.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 Boston Properties, Inc.’sBXP’s three-year, annualized relative TSR performance compared to a custom index.index of peer companies. Under this component, 100% of the target number of LTIP Units will be earned if Boston Properties, Inc.’sBXP’s 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 20212022 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 Boston Properties, Inc.’sBXP’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 Boston Properties, Inc.’sBXP achieves an absolute TSR equal to +1,000 basis points; if Boston Properties, Inc.’sBXP’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 20212022 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 352,021254,061 LTIP Units with a target of approximately 176,009127,031 LTIP Units and linear interpolation between zero and maximum. Earned awards (if any) will vest 100% on February 1, 2024,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 Boston Properties, Inc.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 February 1, 2024,January 31, 2025, earned awards will be calculated based on TSR performance up to the date of the change of control. The 20212022 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 20212022 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, Boston Properties, Inc.BXP will also make a “catch-up” cash payment on the 20212022 MYLTIP Units that are ultimately earned in an amount equal to the regular and special distributions, if any, declared during the performance period on Boston Properties, Inc.’s common stock,BXP’s Common Stock, less the distributions actually paid to holders of 20212022 MYLTIP Units during the performance period on all of the awarded 20212022 MYLTIP Units. Under ASC 718 “Compensation - Stock Compensation,” the 20212022 MYLTIP awards have an aggregate value of approximately $15.3$17.3 million, which amount will generally be amortized into earnings under the graded vesting method.
On February 5, 2021,4, 2022, the measurement period for the Company’s 20182019 MYLTIP awards ended and, based on Boston Properties, Inc.’sBXP’s relative TSR performance, the final awards werepayout was determined to be 29.2%69.0% of target, or an aggregate of approximately $4.6$8.6 million (after giving effect to employee separations). As a result, an aggregate of 285,925 2018144,043 2019 MYLTIP Units that had been previously granted were automatically forfeited.
At Boston Properties, Inc.’s 2021 annual meeting of stockholders held on May 20, 2021, its stockholders approved the Boston Properties, Inc. 2021 Stock Incentive Plan (the “2021 Plan”). The 2021 Plan replaces the 2012 Plan and no further awards will be granted under the 2012 Plan. The material features of the 2021 Plan include, among other things: (i) the maximum number of shares of Common Stock reserved and available for issuance under the 2021 Plan is 5,400,000 shares less one share for every one share that was granted between March 4, 2021 and May 19, 2021 under the 2012 Plan, (ii) shares of Common Stock underlying awards granted under the 2021 Plan or the 2012 Plan that are forfeited, canceled or otherwise terminated (other than by exercise) will be added back to the shares of Common Stock available for issuance under the 2021 Plan and, with respect to “full-value” awards under the 2021 Plan or the 2012 Plan, shares tendered or held back for taxes and shares previously reserved for issuance pursuant to such an award to the extent that such shares are not issued and are no longer issuable pursuant to such an award (e.g., in the event that a full-value award that may be settled in cash or by issuance of shares of Common Stock is settled in cash) will be added back to the shares available for issuance under the 2021 Plan, (iii) the award of stock options (both incentive and non-qualified options), stock appreciation rights, restricted stock units, restricted stock, unrestricted stock, dividend equivalent rights, cash-based awards and other equity-based awards (including LTIP Units) is permitted, (iv) stock options may not be repriced and “underwater” stock options may not be exchanged for another award or cash without stockholder approval; and (v) the term of the 2021 Plan is for ten years from the date of stockholder approval.

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. and Boston Properties Limited Partnership. 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 Boston Properties, Inc.’sBXP’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 ninethree months ended September 30, 2021March 31, 2022 were valued at approximately $5.7$3.9 million ($100.46113.79 per share weighted-average). The LTIP Units granted were valued at approximately $23.8$27.2 million (approximately $84.43$108.41 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 0.65%1.71% and an expected price volatility of 30.0%31.0%. Because the 2012 OPP Units and 2013 - 20212022 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 $8.4$20.9 million and $8.0$19.8 million for the three months ended September 30,March 31, 2022 and 2021, and 2020, respectively, and $42.2 million and $35.3 million for the nine months ended September 30, 2021 and 2020, respectively. At September 30, 2021,March 31, 2022, there was (1) an aggregate of approximately $28.4$37.0 million of unrecognized compensation expense related to unvested restricted stock, LTIP Units and 20182019 MYLTIP Units and (2) an aggregate of approximately $9.4$16.0 million of unrecognized compensation expense related to unvested 20192020 - 20212022 MYLTIP Units that is expected to be recognized over a weighted-average period of approximately 2.12.3 years.

Overview
BXP is one of the largest publicly traded office real estate investment trusts (REITs) (based on total market capitalization as of September 30, 2021)March 31, 2022) in the United States that develops, owns, and manages primarily Class A office properties. 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 space to our tenants.clients. When making leasing decisions, we consider, among other things, the creditworthiness of the tenantclient 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 anyother client’s expansion rights and general economic factors.
Our core strategy has always been to develop, acquire and manage high-quality properties in supply-constrained markets with high barriers-to-entry and attractive demand drivers, and to focus on executing long-term leases with financially strong tenants.clients. Historically, these factors have minimized our exposure in weaker economic cycles and enhanced revenues as market conditions improve. Our tenantclient base is diverse across market sectors and

the weighted-average lease term for our in-place leases, excluding residential units, was approximately 7.57.9 years, as of September 30, 2021,March 31, 2022, including leases signed by our unconsolidated joint ventures. The weighted-average lease term for our 20 largest office tenantsclients, based on leased square footage, was approximately 10.511.2 years as of September 30, 2021.March 31, 2022.
To be successful in any leasing environment, we believe we must consider all aspects of the tenant-landlordclient-landlord relationship. In this regard, we believe that our competitive leasing advantage is based on the following attributes:
our understanding of tenants’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 properties in a sustainable and responsible manner;
our reputation as a premier developer, owner and manager of primarily Class A office properties;
our financial strength and our ability to maintain high building standards; and
our relationships with local brokers.
Outlook
The United StatesJust as the Omicron variant’s impact on the economy continuesbegan to recover fromslowly dissipate, geopolitical tensions in Eastern Europe increased uncertainty during the COVID-19 pandemic, although quarter-over-quarter GDPfirst 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.
As business conditions become more competitive due to rising interest rates, slowing economic growth, slowed to an annual rate of 2.0%and changes in the third quarter of 2021 comparedlabor markets, business leaders will likely feel the need to 6.7% in the second quarter of 2021. This slowdown reflects the impacts of the Delta variantbring their employees together on a much more consistent basis and moderation in government stimulus spending. Since the end of the third quarter, however, daily COVID infection levels have decreased by more than 50% from the recent highs in September 2021.modify their return to office policies. We believe the positive trend in infection rates, combined with relatively low unemployment rates, bodes well for continuing economic growth in our markets.
The overall economic recovery is having a positive impact on our leasing activity. Although additional COVID variants and supply-chain issues may emerge, we believe as the number of vaccinations increases and employees return to their offices in greater numbers, our strategically located, high-quality office and well-amenitized properties will remain a vital component of the strategies of today’s forward-thinking organizations that prioritize fostering collaboration, innovation, productivity and culture, and weculture. We expect tenantscompanies will look to take advantage of the availability of Class A space and upgrade.
Annual inflation increased to 5.4% in September 2021, driven largely by energy prices, which increased approximately 25% compared to one year ago. Energy is a component of our operating expenses our largest energy cost is electricity. We have limited most of our exposure to additional potential increases through 2022, and we have been increasing our procurement from green power. We remain exposed to the marginal cost of electrical generation in the Boston region where we expect increases in 2022 of greater than 10% compared to last year. Costs for security, cleaning and engineering labor continues to increase due to labor shortages across all trades. However, we are able to mitigate the risks from these increased costs to our results due to the nature of our lease contracts, which generally take one of two forms: (1) net leases, under which all of the operating expense and real estate taxes are paid by the tenant, and (2) gross leases with a base year that is set upon the lease commencement with increases in expenses over that base year added to the rental obligation of the tenant. Our near-term exposure to increases in operating expenses is primarily on our vacant space and for new or renewal leases where we are setting a base year. Our vacancy was approximately 11.6% at September 30, 2021, and our 2021 and 2022 lease expirations total approximately 7.6% of our portfolio. We do not expect an increase in operating expenses to have a material adverse effect on our results of operations for the remainder of 2021 or 2022.

We remain focused on the following priorities:priorities, which we believe are key to increasing future revenue and asset values over the long-term:
ensuring tenantclient health, safety and satisfaction;
leasing available space in our in-service and development properties, as well as proactively focusing on future lease expirations;
completing the construction and leasing of our development properties;

The following is an overview of portfolio activity, leasing activity and capital marketsinvestment activity in the thirdfirst quarter of 2021.2022.
Leasing Activity and Occupancy
In the thirdfirst quarter of 2021,2022, we signed approximately 1.41.2 million square feet of new leases and renewals, which is in line with our 10-year, pre-pandemic average for leasing for the first quarter. These leases have a weighted-average lease term of approximately 9.27.3 years, indicating that many new and existing tenantsclients continue to commit to

the long-term use of space and view our properties as their preferred choice for a premium Class A office environment. The volume of leasing in the third quarter of 2021 (measured by square feet) was more than double the volume achieved in the first quarter of 2021 and approximately 90% of our pre-pandemic historical third quarter average.
The overall occupancy of our in-service office and retail properties was 88.4%89.1% at SeptemberMarch 31, 2022, an increase of 30 2021, a decreasebasis points from December 31, 2021.

We anticipateleases signed, but for which occupancy for the remainder of 2021 will be relatively flat with occupancy for the third quarter of 2021, but will begin to improve as we head into 2022, as our remaining 2021 and 2022 lease expirations are backfilled by signed leases that havehas not yet commenced, and new leases.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 $23.5$21.7 million in the thirdfirst quarter of 2021, an increase2022, a decrease of approximately $5.2$1.4 million, or 6%, from the secondfourth quarter of 2021. The increase was primarily due to improved transient parking and greater insurance proceeds from a water main break at a New York property. The third quarter 2021 parking and other revenue was 92% of pre-pandemic parking and other revenue from the third quarter of 2019. We expect to return to pre-pandemic levels of parking revenue as workers increasingly return to work in their offices.
Our hotel property, the Boston Marriott Cambridge, generatedalso experienced a decrease in revenue of approximately $1.2$1.7 million, of net operating income duringor 27%, from the thirdfourth quarter of 2021. This wasWe believe both decreases are correlated to the spike in the Omicron variant throughout the U.S. in the first quarter since the startpart of the pandemic in which the hotel made a positive contribution to our results.

Investment Activity
We remain committed to developing and acquiring assets to enhance our long-term growth and to meet tenantclient demand for high-quality office, residential, and lablife 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 properties in each of our chosen markets.
DuringConsistent with this strategy, on April 14, 2022, we entered into an agreement to acquire Madison Centre, a Class A office property in the thirdSeattle, Washington central business district (“CBD”), for a gross purchase price of $730 million. This addition to our portfolio furthers our goal to establish a strong platform for continued growth 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 2021,this year and will be initially funded with a one-year, $730 million term loan. We anticipate ultimately funding the acquisition through incremental asset sales, which we continued to execute on our strategy and completedanticipate would be structured as like-kind exchanges or joint venture equity.
In the first quarter of 2022, we commenced two acquisitions. We believe these investments align with several elements of our growth strategy, including entering new markets or submarkets that exhibit strong demand and limitations on supply, uncovering opportunities that utilize our leasing and redevelopment skills to increase value, broadening our portfolio to meet the current and anticipated future

In addition, during September and October of 2021, we completed and delivered approximately 1.5 million square feet of space to tenants from our development pipeline.
In early 2021 we added several new development and redevelopment projects to our development pipeline focused on the specific needs of tenants in the life sciences sector. Our lab/life sciences developments in our pipeline total approximately 920,000 square feet and include properties in Waltham, Massachusetts and South San Francisco, California. Although Shady Grove Bio+Tech Campus is not currently included in our development pipeline, we anticipate converting the office buildings on the campus to lab space. Our lab/life sciences developments are located in some of the largest life sciences clusters in the United States, with strong demand from tenants because of the close proximity to universities, research institutions and related businesses and concentrations of labor with specialized skills and knowledge.
Supply-chain concerns and inflationary pressures continue to negatively impact our business bothand have been exacerbated by the war in Ukraine and the ongoing Omicron outbreak in China. Impacts on our business include increased time to completioncomplete construction projects and increased costs. Our construction schedule is one of the criteriaelements we useconsider 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 are workingcontinue 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, impact schedules.directly or indirectly, cause delays. We are intentionally minimizing the amount of materials we acquire from overseas,foreign suppliers, releasing material packages as early as possible and, stock-pilingwhen appropriate, purchasing materials in advance and storing them off-site. In addition, when budgeting new development projects, we are including projected cost increases of approximately 5-6%.

Certain accounting policies are considered to be critical accounting policies, as they require management to make assumptions about matters that are highly uncertain at the time the estimate is made and changes in accounting estimate are reasonably likely to occur from period to period. Management bases its estimates and assumptions on historical experience and current economic conditions. On an on-going basis, management evaluates its estimates and assumptions including those related to revenue, impairment of long-lived assets and the allowance for doubtful accounts. Actual results may differ from those estimates and assumptions.

At September 30,March 31, 2022 and 2021, and 2020, we owned or had joint venture interests in a portfolio of 202201 and 196 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 provides a complete understanding of our operating results.is meaningful. Therefore, the comparison of operating results for the three and nine months ended September 30,March 31, 2022 and 2021 and 2020 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 in development or redevelopment after the beginning of the earliest period presented or disposed of prior to the end of the latest period presented.

Net operating income (“NOI”)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, interest and other income (loss), gains (losses) 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 of 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, 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, 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 ninethree months ended September 30, 2021March 31, 2022 to the ninethree months ended September 30, 2020March 31, 2021

Same Property Portfolio
Lease Revenue (Excluding Termination Income)
Lease revenue (excluding termination income) from the Same Property Portfolio increased by approximately $51.8$22.9 million for the ninethree months ended September 30, 2021March 31, 2022 compared to 2020. Approximately $59.6 million of the2021. The increase was related to write-offsa result of accrued rent and accounts receivable balances that occurred during the nine months ended September 30, 2020 and did not recur in 2021, for primarily retail tenants that either terminated their leases or we determined that the accrued rent and/or accounts receivable balances were no longer probable of collection. Excluding the write-offs, the Same Property Portfolio decreasedour average revenue per square foot increasing by approximately $7.8 million due to average occupancy decreasing from 93.4% to 91.7%, resulting in a decrease of$2.96, contributing approximately $62.9$25.7 million, partially offset by an increase inapproximately $2.8 million decrease due to our average revenue per square foot by approximately $1.08, contributing approximately $55.1 million.
We continueoccupancy decreasing from 91.5% to evaluate the collectability of our accrued rent and accounts receivable balances related to lease revenue. If after a write-off has been recorded, (1) we subsequently determine that we are probable we will collect substantially all the remaining lessee’s lease payments under the lease term and (2) the lease has not been modified since the write-off, we will then reinstate the accrued rent and accounts receivable write-offs, adjusting for the amount related to the period when the lease payments were considered not probable of collection. If our estimate of collectability differs from the cash received, then the timing and amount of our reported revenue could be impacted.
Each quarter since the second quarter of 2020, the number of executed COVID-19 lease modifications has decreased and as of the third quarter of 2021, we are executing COVID-19 modifications on a limited basis.91.1%.
Termination Income
Termination income increaseddecreased by approximately $3.1$2.2 million for the ninethree months ended September 30, 2021March 31, 2022 compared to 2020.2021.
Termination income for the ninethree months ended September 30, 2021March 31, 2022 related to 23ten tenants across the Same Property Portfolio and totaled approximately $11.5$1.5 million, which was primarily related to tenants that terminated leases early in New York City and the Boston region.San Francisco. In addition, we received a distribution from our unsecured credit claim against Lehman Brothers, Inc. of approximately $0.6 million.
Termination income for the ninethree months ended September 30, 2020March 31, 2021 related to 3411 tenants across the Same Property Portfolio and totaled approximately $8.4$4.3 million, of which $3.7 million was primarily related to tenantsa retail tenant in the Boston region that terminated leases early in New York City.closed all of its retail stores.
Parking and Other Revenue
Parking and other revenue increased by approximately $3.3$4.7 million for the ninethree months ended September 30, 2021March 31, 2022 compared to 2020.2021. Parking revenue and other revenue increased by approximately $0.8$6.2 million and $2.5 million, respectively. The increase in parking revenue was primarily due to an increase in transient parking. The increase in other revenue was primarily due to approximately $5.1 million in insurance proceeds related to damage at one of our properties in the New York region due to a water main break, partially offset by a decrease in other revenue of approximately $2.6 million related to tenant restoration obligation payments in 2020 that did not recur in 2021.

(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.
Hotel Net Operating Loss
The Boston Marriott Cambridge hotel property operatedcontinues to operate at a loss, ofhowever, the net operating loss decreased by approximately $0.6$1.1 million for the ninethree months ended September 30,March 31, 2022 compared to 2021. This is approximately $4.3 million less than the nine months ended September 30, 2020.
The decreased demand for and occupancy of the Boston Marriott Cambridge closed in March 2020 due to COVID-19. The hotel re-opened on October 2, 2020 and has operated at lower occupancy levels due to the continued impact of COVID-19 on business and leisure travel. The closing of the hotel for more than two fiscal quarters, and the lower demand and low occupancy since its re-opening, have had, and are expected to continue to have, a material adverse effect on the hotel’sits operations. We expect hotel occupancy to remain low until the demand for business and leisure travel returns to historical levels.

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.

This increasedecrease was partially offset by (1) an approximately $5.8$6.9 million gain on sale of real estate from the sale of Annapolis Junction Building Eight and two undeveloped land parcels during the nine months ended September 30, 2020 and (2) an approximately $1.1 million decreaseincrease in net income from our Metropolitan Square joint venture, primarily related toplacing in-service (1) 7750 Wisconsin Avenue (Marriott International Headquarters) in Bethesda, Maryland, (2) 100 Causeway Street in Boston, Massachusetts and (3) increased interest expense related toleasing at the mortgage refinancing.Hub50House residential property 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.

Interest and Other Income (Loss)
Interest and other income (loss) decreasedincreased by approximately $0.1 million for the ninethree months ended September 30, 2021March 31, 2022 compared to 2020,2021, due primarily to a decrease of approximately $2.9 million in interest income as a result of lower interest earned on our deposits, partially offset by an approximately $2.8$0.1 million decrease in the allowance for current expected credit losses, which results in higher income.
On January 1, 2020, we adopted Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”) and, as a result, we were required to record an allowance for current expected credit losses related to our outstanding (1) related party note receivable, (2) notes receivable and (3) off-balance sheet credit exposures.
Gains (Losses) from Investments in Securities
Gains (losses) from investments in securities for the ninethree months ended September 30,March 31, 2022 and 2021 and 2020 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 ninethree months ended September 30,March 31, 2022 and 2021, and 2020, we recognized gains (losses) of approximately $3.7$(2.3) million and $1.0$1.7 million, respectively, on these investments. By comparison, our general and administrative expense increased (decreased) by approximately $3.7$(2.3) million and $1.0$1.7 million during the ninethree months ended September 30,March 31, 2022 and 2021, and 2020, respectively, as a result of increases (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.

(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 2021 Credit Facility, which replacedfact 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 2017 Credit Facility (See Note 8current 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.

Development and Management Services Revenue
Development and management services revenue decreased by approximately $1.0 million for the three months ended March 31, 2022 compared to 2021. Development services revenue and management services revenue decreased by approximately $0.9 million and $0.1 million, respectively. The decrease in development services revenue was primarily related to a decrease in development fees. The decrease in management services revenue was primarily related to a decrease in leasing commissions earned from a third-party owned building in the Washington, DC region, partially offset by an increase in asset management fees earned from an unconsolidated joint venture in Seattle.
General and Administrative Expense
General and administrative expense decreased by approximately $1.8 million for the three months ended March 31, 2022 compared to 2021 primarily due to a decrease in compensation expense of approximately $3.6

million, partially offset by an increase of approximately $1.8 million in other general and administrative expenses. The decrease in compensation expense primarily related to an approximately $4.0 million decrease in the value of our deferred compensation plan. The increase in other general and administrative expenses primarily related to an increase in professional fees.
Wages directly related to the development of rental properties isare capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over the useful lives of the real estateapplicable asset or lease term. As portions of properties are placed in-service, we cease capitalizing interest on that portion and interest is then expensed.

These costs are not included in the interest expense referencedgeneral and administrative expenses discussed above.
On October 15,Transaction Costs
Transaction costs decreased by approximately $0.3 million for the three months ended March 31, 2022 compared to 2021 BPLP used available cash and funds under its 2021 Credit Facility to complete the redemption of $1.0 billion in aggregate principal amount of its 3.85% senior notes due February 1, 2023. The redemption price was approximately $1.05 billion, which was equal to par plus approximately $7.9 million of accrued and unpaid interest to, but not including, the redemption date and an early redemption premium and unamortized financing costs totaling approximately $43.9 million. We expect to recognize a loss from early extinguishment of debt related primarily to joint venture formation costs that occurred during the paymentthree months ended March 31, 2021. In general, transaction costs relating to the formation of new and pending 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 redemption premiumreal 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 fourth quarter.Explanatory Note that follows the cover page of this Quarterly Report on Form 10-Q.

(1)The increase was primarily attributable to an increase in lease revenue from our tenants. In addition, during the nine months ended September 30, 2020, we accelerated amortization expense related to a below-market lease that terminated early.
(2)During the nine months ended September 30, 2020, we wrote off approximately $26.8 million of accrued rent and accounts receivable balances for tenants that either terminated their leases or for which we determined their accrued rent and/or accounts receivable balances, primarily retail tenants, were no longer probable of collection. Approximately $12.0 million represents our partners’ share of the write-offs.
(3)The decrease was primarily due to a decrease in lease revenue from our retail tenants and a tenant that terminated its space during the nine months ended September 30, 2020, partially offset by the increase in revenue related to placing in-service One Five Nine East 53rd Street. During the nine months ended September 30, 2020, we wrote off approximately $2.9 million of accrued rent and accounts receivable balances for tenants that either terminated their leases or for which we determined their accrued rent and/or accounts receivable balances, primarily retail tenants, were no longer probable of collection. Approximately $1.3 million represents our partners’ share of the write-offs.
Noncontrolling Interest—Common Units of the Operating Partnership
For BXP, noncontrolling interest—common units of the Operating Partnership decreased by approximately $61.7 million for the nine months ended September 30, 2021 compared to 2020 due primarily to a decrease in allocable income, which was the result of recognizing a greater gain on sales of real estate amount during 2020.

Income from Unconsolidated Joint Ventures
For the three months ended September 30,March 31, 2022 compared to 2021, income from unconsolidated joint ventures decreased by approximately $3.0 million due to a $10.3 million gain on sale of investment from the sale of our Annapolis Junction joint venture during the three months ended September 30, 2020” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.
Below are reconciliations ofMarch 31, 2021. This decrease was partially offset by an approximately $6.9 million increase in net income attributablefrom placing in-service (1) 7750 Wisconsin Avenue (Marriott International Headquarters) in Bethesda, Maryland, (2) 100 Causeway Street in Boston, Massachusetts and (3) increased leasing at the Hub50House residential property 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 Boston Properties, Inc. common shareholderscertain properties. The difference between the real estate assets of BXP as compared to NOI and net income attributable to Boston Properties Limited Partnership common unitholders to NOIBPLP 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.

Comparison of the three months ended September 30, 2021 to the three months ended September 30, 2020
The table below shows selected operating information for the Same Property PortfolioInterest and the Total Property Portfolio. The Same Property Portfolio consists of 143 properties totalingother income (loss) increased by approximately 39.7$0.1 million net rentable square feet, excluding unconsolidated joint ventures. The Same Property Portfolio includes properties acquired or placed in-service on or prior to July 1, 2020 and owned and in-service through September 30, 2021. The Total Property Portfolio includes the effects of the other properties either acquired, placed in-service, in development or redevelopment after July 1, 2020 or disposed of on or prior to September 30, 2021. This table includes a reconciliation from the Same Property Portfolio to the Total Property Portfolio by also providing information for the three months ended September 30,March 31, 2022 compared to 2021, due to an approximately $0.1 million decrease in the allowance for current expected credit losses, which results in higher income.
Gains (Losses) from Investments in Securities
Gains (losses) from investments in securities for the three months ended March 31, 2022 and 20202021 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 respect toequivalent assets and thereby limit our market risk. The performance of these investments is recorded as gains (losses) from investments in securities. During the properties that were acquired, placed in-service, in development or redevelopment or sold. We did not sell any propertiesthree months ended March 31, 2022 and 2021, we recognized gains (losses) of approximately $(2.3) million and $1.7 million, respectively, on these investments. By comparison, our general and administrative expense increased (decreased) by approximately $(2.3) million and $1.7 million during the three months ended September 30,March 31, 2022 and 2021, and 2020.

Same Property Portfolio
Lease Revenue (Excluding Termination Income)
Lease revenue (excluding termination income) from the Same Property Portfolio increased by approximately $21.8$22.9 million for the three months ended September 30, 2021March 31, 2022 compared to 2020. Approximately $7.5 million2021. The increase was a result of the increase related to write-offs of accrued rent and accounts receivable balances that occurred during the three months ended September 30, 2020 and did not recur in 2021, for primarily retail tenants that either terminated their leases or we determined that the accrued rent and/or accounts receivable balances were no longer probable of collection. Excluding the write-offs, the Same Property Portfolio increased by approximately $14.3 million primarily due to our average revenue per square foot increasing by approximately $2.77, resulting in an increase of$2.96, contributing approximately $24.1$25.7 million, partially offset by an approximately $9.8$2.8 million decrease due to our average occupancy decreasing from 92.4%91.5% to 91.0%91.1%.
We continue to evaluate the collectability of our accrued rent and accounts receivable balances related to lease revenue. If after a write-off has been recorded, (1) we subsequently determine that we are probable we will collect substantially all the remaining lessee’s lease payments under the lease term and (2) the lease has not been modified since the write-off, we will then reinstate the accrued rent and accounts receivable write-offs, adjusting for the amount related to the period when the lease payments were considered not probable of collection. If our estimate of collectability differs from the cash received, then the timing and amount of our reported revenue could be impacted.
Each quarter since the second quarter of 2020, the number of executed COVID-19 lease modifications has decreased and as of the third quarter of 2021, we are executing COVID-19 modifications on a limited basis.
Termination Income

Parking revenue and other revenue increased by approximately $6.3$6.2 million and $0.8 million, respectively.was partially offset by a decrease in other revenue of approximately $1.5 million. The increase in parking revenue was primarily due to an increase in transient and monthly parking.The decrease in other revenue was due to a decrease in insurance proceeds received during the three months ended March 31, 2022 compared to 2021.
Real Estate Operating Expenses
Real estate operating expenses from the Same Property Portfolio decreasedincreased by approximately $1.1$10.8 million, or 0.4%4.3%, for the three months ended September 30, 2021March 31, 2022 compared to 2020,2021, due primarily to an increase of approximately $15.1 million, or 16.2%, in operating expenses, including cleaning, utilities, repairs and maintenance, and roads/grounds/security, and other real estate operating expenses of $1.7 million, or 7.9%, partially offset by a decrease in real estate taxes of approximately $5.9$6.0 million, or 4.4%, offset4.5%. The increase in operating expenses is driven by an increase in utility and other real estate operating expenses of approximately $3.1 million, or 12.1%, and $1.7 million, or 1.9%, respectively.physical tenant occupancy. The decrease in real estate taxes was primarily experienced in New York City. The increase in utility expense was experienced across the portfolio and was primarily driven by an increase in physical tenant occupancy, which led to higher demand for electricity and HVAC.

_______________  
(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.
Hotel Net Operating Income (Loss)Loss
The Boston Marriott Cambridge hotel property operatedcontinues to operate at ana loss, however, the net operating loss decreased by approximately $1.2$1.1 million profit duringfor the three months ended September 30,March 31, 2022 compared to 2021. This is approximately $4.3 million greater than the three months ended September 30, 2020.
The decreased demand for and occupancy of the Boston Marriott Cambridge closed in March 2020 due to COVID-19. The hotel re-opened on October 2, 2020 and has operated at lower occupancy levels due to the continued impact of COVID-19 on business and leisure travel. The closing of the hotel for more than two fiscal quarters, and the lower demand and low occupancy since its re-opening, have had, and are expected to continue to have, a material adverse effect on the hotel’sits operations. We expect hotel occupancy to remain low until the demand for business and leisure travel returns to historical levels.

Development services revenue and management services revenue decreased by approximately $1.1$0.9 million and $0.1 million, respectively. The decrease in development services revenue was primarily related to a decrease of approximately $0.6 million in development fees earned in New York City from an unconsolidated joint venture and a decrease of approximately $0.5 million in fees associated with tenant improvement projects earned from a building owned by a third-party in the Washington, DC region.fees. The decrease in management services revenue was primarily related to a decrease in propertyleasing commissions earned from a third-party owned building in the Washington, DC region, partially offset by an increase in asset management fees earned from third-party owned buildingsan unconsolidated joint venture in the Washington, DC region.Seattle.

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.

Gains (Losses) from Investments in Securities
Gains (losses) from investments in securities for the three months ended September 30,March 31, 2022 and 2021 and 2020 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 three months ended September 30,March 31, 2022 and 2021, and 2020, we recognized gains (losses) of approximately $(0.2)$(2.3) million and $1.9$1.7 million, respectively, on these investments. By comparison, our general and administrative expense increased (decreased) by approximately $(0.2)$(2.3) million and $1.9$1.7 million during the three months ended September 30,March 31, 2022 and 2021, and 2020, respectively, as a result of increases (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.

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 our prior unsecured revolving credit agreement (the “2017 Credit Facility”).

(1) On June 15, 2021, BPLP entered into the 2021 Credit Facility, which replaced the 2017 Credit Facility (See Note 8 to the Consolidated Financial Statements).
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,March 31, 2022 and 2021 and 2020 was approximately $11.6$13.7 million and $13.5$12.0 million, respectively. These costs are not included in the interest expense referenced above.
On October 15, 2021, BPLP used available cash and funds under its 2021 Credit Facility to complete the redemption of $1.0 billion in aggregate principal amount of its 3.85% senior notes due February 1, 2023. The redemption price was approximately $1.05 billion, which was equal to par plus approximately $7.9 million of accrued and unpaid interest to, but not including, the redemption date and an early redemption premium and unamortized financing costs totaling approximately $43.9 million. We expect to recognize a loss from early extinguishment of debt related primarily to the payment of the redemption premium in the fourth quarter.
At September 30, 2021,March 31, 2022, our outstanding variable rate debt consisted of BPLP’s $1.5 billion Revolving Facility.unsecured credit facility (the “Revolving Facility”).

Noncontrolling Interest—Common Units of the Operating Partnership
For BXP, noncontrolling interest—common units of the Operating Partnership increased by approximately $2.0$5.3 million for the three months ended September 30, 2021March 31, 2022 compared to 20202021 due primarily to an increase in allocable income.income, which was partially 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.
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, 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, we 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. 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.
Liquidity and Capital Resources
General
Our principal liquidity needs for the next twelve months and beyond are to:
fund normal recurring expenses;
meet debt service and principal repayment obligations, including balloon payments on maturing debt;
fund 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 2021 CreditRevolving 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 through our Strategic Capital Program (“SCP”) with large institutional investors; and
issuances of BXP equity securities and/or preferred or common units of partnership interestinterests in BPLP.
We draw on multiple financing sources to fund our long-term capital needs. We expect to fund our current developmentdevelopment/redevelopment properties primarily with our available cash balances, construction loans 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), 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 tenant turnover and controlling operating expenses. Our sources of revenue also include third-party fees generated by our property management, leasing, and 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. 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.
Leasing activity and revenue from transient parking and our hotel improved during the third quarter of 2021.We signed approximately 1.4 million square feet of leases in the quarter, which represents more than double the leasing volume in the first quarter of 2021 and is approximately 90% of our pre-pandemic average for the third quarter. Our parking and hotel revenue also increased approximately 36% compared to the second quarter of 2021. We expect parking revenue to continue to improve gradually as the return to in-person work accelerates and hotel occupancy to remain low until the demand for business and leisure travel returns to historical levels.
Ourour primary uses of capital over the next twelve months will be the commencement, continuation and completion of our current and committed development and redevelopment projects, the acquisition of Madison Centre, servicing the principal and interest payments on our outstanding indebtedness and satisfying our REIT distribution requirements.
As of September 30, 2021,March 31, 2022, we had nine11 properties under development or redevelopment. Our share of the remaining development and redevelopment costs that we expect to fund through 20242026 was approximately $1.1$1.2 billion. In January 2022, we commenced the redevelopment of 651 Gateway in South San Francisco, California, a project in which we own a 50% interest, and in February 2022, we restarted the first phase of our Platform 16 development project in San Jose, California, a project in which we own a 55% interest (see Note 5 to the Consolidated Financial Statements).
DuringIn July 2021, we announced the third quarterformation of 2021, BPLP completedan investment program with two partners committing a public “green bond” offeringtargeted equity investment of $850.0 million of 2.450% unsecured senior notes due October 2033. The offering marked BPLP’s fourth green bond offering and represented the lowest coupon ever issued by BPLP. The net proceeds from the offering along with available cash and borrowings under BPLP’s Revolving Facility were used to fully redeem the $1.0 billion, aggregate principal amount of 3.85% unsecured senior notesincluding $250 million from us. Under this agreement, we will provide these partners, for up to two years, exclusive first offers to form joint ventures with us to invest in assets that were scheduledmeet target criteria. All investments are discretionary to mature in February 2023. each partner.
The early repayment will result in a loss from early extinguishment of debt of approximately $43.9 million in the fourth quarter of 2021. This amount includes approximately $1.0 million of unamortized financing and other costs.
We have a SCP that 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 fees paid to us,fee income, and in certain partnerships, a greater share of income upon achieving certain success criteria. These large financial partners include some of the world’s largest sovereign wealth funds and pension plans. 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. As part of the broader SCP,
On April 14, 2022, we announced in July 2021 the formation ofentered into an investment program with two large partners committing a targeted equity investment of $1.0 billion, including $250 million from us. Under this agreement we will provide these partners, for up to two years, exclusive first offers to form joint ventures with us to invest in assets that meet the SCP’s target criteria. All investments are discretionary to each partner.
For example, during the third quarter of 2021, we partnered with two SCP partners to acquire Safeco Plaza, a 50-story,purchase Madison Centre, an approximately 765,000 net rentable760,000 square foot, LEED-Platinum certified,37-story Class A office property locatedbuilding in Seattle, Washington. After mortgage financing, the partners contributed approximately $215 million to fund the acquisition. Each partner owns approximatelyWashington for a one-third ownership interest in the property (See Note 5 to the Consolidated Financial Statements).
In addition, we expect to acquire 360 Park Avenue South, located in New York, New York, for agross purchase price of approximately $300 million$730.0 million. The acquisition is expected to close in the fourthsecond quarter of 2021. At closing,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 will assumeanticipate would be structured as like-kind exchanges, or joint venture equity.
We have no debt maturities until September 2023. Our unconsolidated joint ventures have one loan maturing in 2022, of which our share of the aggregate outstanding principal is approximately $202 million of$88.2 million. We are currently in the market to refinance this maturity with a mortgage debt and issue approximately $98 million of OP Units, with a floor price of $111 per OP Unit. Otherin an amount equal to or greater than customary closing costs, no cash is required to close the transaction. We expect to fund future investment in this asset through a joint venture with one or more financial partners from the SC Program.current balance.

On OctoberApril 25, 2021,2022, we completed the sale of our 181, 191 and 201 Spring Street properties, located in Lexington, Massachusetts, for a gross sales price of $191.5 million.
We have no debt maturities during the remainder of 2021. We have one loan maturing in 2022 that has an outstanding principal balancehad available cash of approximately $618.7$313.8 million (of which approximately $103.8 million is attributable to our share is approximately $340.3 million)consolidated joint venture partners). The loan is secured by our 601 Lexington Avenue property in New York. Our unconsolidated joint ventures have two loans maturing in 2022, of which our share of outstanding principal is approximately $147.0 million. We are currently in the market to refinance the 601 Lexington Avenue mortgage. Due to the increase in cash flow from this asset, due in part to the redevelopment completed earlier in 2021, we anticipate increasing the principal amount of the mortgage and reducing the interest rate as part of the refinancing. There can be no assurance that this refinancing will be consummated on the terms currently contemplated or at all.
Although the current and future impact of COVID-19 on our liquidity and capital resources will depend on a wide range of factors, we believe that our access to capital and our strong liquidity, including the approximately $1.2$1.3 billion available under the 2021 CreditRevolving Facility and our available cash, of approximately $362.7 million (of which approximately $122.2 million is attributable to our consolidated joint venture partners), as of November 2, 2021, isApril 25, 2022, are sufficient to fund our remaining capital requirements on existing development and redevelopment projects, fund acquisitions, repay our maturing indebtedness when due, satisfy our REIT distribution requirements and still allow us to act opportunistically on attractive investment opportunities.
We have not sold any shares under BXP’s $600.0 million “at the market” equity offering program.

We may seek to enhance our liquidity to fund our foreseeable potentialcurrent and future development activity, pursue additional attractive investment opportunities and refinance or repay indebtedness. Depending on interest rates, andthe overall conditions in the debt and public and private equity markets, and our leverage at the time, we may decide to access eitherone or bothmore of these markets in advancecapital sources (including utilization of BXP’s $600.0 million “at the need for the funds.market” equity offering program). Doing so may result in us carrying additional cash and cash equivalents pending our use of the proceeds, which wouldcould increase our net interest expense andor be dilutive to our earnings.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 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 including the impact of COVID-19, 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.
Cash Flow Summary

Our principal source of cash flow is related to the operation of our properties. The weighted-average term of our in-place leases, excluding residential units, was approximately 7.57.9 years as of September 30, 2021,March 31, 2022, including leases signed by our unconsolidated joint ventures, with occupancy rates historically in the range of 88% to 94%. Generally, our properties generate a relatively consistent stream of cash flow that provides us with resources to pay operating expenses, debt service and fund regular quarterly dividend and distribution payment requirements.

addition, over the past several years, we have raised capital through the sale of some of our properties and through secured and unsecured borrowings.
The full extent of the impact of COVID-19 on our business, operations and financial results will depend on numerous evolving factors that we may not be able to accurately predict. In addition, we cannot predict the impact that COVID-19 will have on our tenants, employees, contractors, lenders, suppliers, vendors and joint venture partners; any material adverse effect on these parties could also have a material adverse effect on us.
Cash is used in investing activities to fund acquisitions, development, net investments in unconsolidated joint ventures and maintenance and repositioning capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing and property management skills and invest in existing buildings to enhance or maintain our market position.

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:
(1)     our consolidated debt; plus
(2)     the product of (x) the closing price per share of BXP common stockCommon Stock on September 30, 2021,March 31, 2022, as reported by the New York Stock Exchange, multiplied by (y) the sum of:
(i)     the number of outstanding shares of common stockCommon 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, 2013 - 20182019 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, 20192020 - 20212022 MYLTIP Units are not included in this calculation as of September 30, 2021.March 31, 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

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 96 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
64

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
93

Table of Contents
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.

Contractual Obligationspurchase 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 September 30, 2021,March 31, 2022, we paid approximately $67.8$70.1 million to fund tenant-related obligations, including tenant improvements and leasing commissions.
In addition, during the three months ended September 30, 2021,March 31, 2022, we and our unconsolidated joint venture partners incurred approximately $102.9$90.8 million of new tenant-related obligations associated with approximately 1.41.2 million square feet of second generation leases, or approximately $73$79 per square foot. We did not sign anysigned approximately 21,000 square feet of first generation leases during the three months ended September 30, 2021.leases. The tenant-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 first quarter of 2022, we signed leases for approximately 1.2 million square feet of space and incurred aggregate tenant-related obligations of approximately $94.9 million, or approximately $80 per square foot.

At September 30, 2021,March 31, 2022, the weighted-average coupon/stated rates on the fixed rate debt stated above was 3.47%3.32% per annum. At March 31, 2022, our outstanding variable rate debt based on LIBOR totaled
approximately $255.0 million. At March 31, 2022, the coupon/stated rate on our variable rate debt was
approximately 1.02% 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 million for the three months ended March 31, 2022.
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”). 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.

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.

Table of Contents
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.

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 usebusiness 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 joint venturestalent, rising inflation and participationinterest rates, volatility in a co-investment program may limit our flexibility with jointly owned investmentsthe public equity and debt markets, and international economic and other assets weconditions, including pandemics, geopolitical instability (such as the war in Ukraine), sanctions and other conditions beyond our control.

the financial condition of our tenants may be adversely affected, which may result in tenant 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 joint venture partnersability to borrow on terms and conditions that we find acceptable, or at all, may have different objectives than we have regarding the appropriate timingbe limited, which could reduce our ability to pursue acquisition and terms of any sale or refinancing of a property, its operation or, if applicable, the commencement ofdevelopment opportunities and refinance existing debt, reduce our returns from our acquisition and development activities and we could become engaged in a dispute with any ofincrease our joint venture partners that could lead to the sale of either parties’ ownershipfuture interest or the property;expense;
