Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview	Overview Organization and Business Description Douglas Emmett, Inc. is a fully integrated, self-administered and self-managed REIT. We are one of the largest owners and operators of high-quality office and multifamily properties in Los Angeles County, California and Honolulu, Hawaii. Through our interest in our Operating Partnership and its subsidiaries, consolidated JVs and unconsolidated Fund, we focus on owning, acquiring, developing and managing a substantial market share of top-tier office properties and premier multifamily communities in neighborhoods that possess significant supply constraints, high-end executive housing and key lifestyle amenities. The terms "us," "we" and "our" as used in the consolidated financial statements refer to Douglas Emmett, Inc. and its subsidiaries on a consolidated basis. At December 31, 2021, our Consolidated Portfolio consisted of (i) a 17.8 million square foot office portfolio, (ii) 4,388 multifamily apartment units and (iii) fee interests in two parcels of land from which we receive rent under ground leases. We also manage and own an equity interest an unconsolidated Fund which, at December 31, 2021, owned an additional 0.4 million square feet of office space. We manage our unconsolidated Fund alongside our Consolidated Portfolio, and we therefore present the statistics for our office portfolio on a Total Portfolio basis. As of December 31, 2021, our portfolio (not including two parcels of land from which we receive rent under ground leases), consisted of the following properties (including ancillary retail space): Consolidated Portfolio Total Portfolio Office Wholly-owned properties 53 53 Consolidated JV properties 16 16 Unconsolidated Fund properties — 2 69 71 Multifamily Wholly-owned properties 11 11 Consolidated JV properties 1 1 12 12 Total 81 83 Basis of Presentation The accompanying consolidated financial statements are the consolidated financial statements of Douglas Emmett, Inc. and its subsidiaries, including our Operating Partnership and our consolidated JVs. All significant intercompany balances and transactions have been eliminated in our consolidated financial statements. We consolidate entities in which we are considered to be the primary beneficiary of a VIE or have a majority of the voting interest of the entity. We are deemed to be the primary beneficiary of a VIE when we have (i) the power to direct the activities of that VIE that most significantly impact its economic performance, and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. We do not consolidate entities in which the other parties have substantive kick-out rights to remove our power to direct the activities, most significantly impacting the economic performance, of that VIE. In determining whether we are the primary beneficiary, we consider factors such as ownership interest, management representation, authority to control decisions, and contractual and substantive participating rights of each party. We consolidate our Operating Partnership through which we conduct substantially all of our business, and own, directly and through subsidiaries, substantially all of our assets, and are obligated to repay substantially all of our liabilities. The consolidated debt, excluding our consolidated JVs, was $3.41 billion and $3.19 billion, as of December 31, 2021 and December 31, 2020, respectively. See Note 8. We also consolidate three JVs through our Operating Partnership (four JVs before December 31, 2020 - see "2020 Property Disposition" in Note 3 for more information regarding the dissolution of one of our JVs before December 31, 2020). We consolidate our Operating Partnership and our three JVs because they are VIEs and we or our Operating Partnership are the primary beneficiary for each. As of December 31, 2021, our consolidated VIE entities, excluding our Operating Partnership, had aggregate consolidated assets of $3.56 billion (of which $3.28 billion related to investment in real estate) and aggregate consolidated liabilities of $1.72 billion (of which $1.64 billion related to debt). As of December 31, 2020, our consolidated VIE entities, excluding our Operating Partnership, had aggregate consolidated assets of $3.58 billion (of which $3.37 billion related to investment in real estate) and aggregate consolidated liabilities of $1.73 billion (of which $1.59 billion related to debt). The accompanying consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC in conformity with US GAAP as established by the FASB in the ASC. The accompanying consolidated financial statements include, in our opinion, all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial information set forth therein. Any references to the number or class of properties, square footage, per square footage amounts, apartment units and geography, are unaudited and outside the scope of our independent registered public accounting firm’s audit of our consolidated financial statements in accordance with the standards of the PCAOB.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates The preparation of consolidated financial statements in conformity with US GAAP requires management to make certain estimates that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Investment in Real Estate Acquisitions and Initial Consolidation of VIEs We account for property acquisitions as asset acquisitions, and include the acquired properties' results of operations in our results of operations from the respective acquisition date. We allocate the purchase price for asset acquisitions, which includes the capitalized transaction costs, and for the properties upon the initial consolidation of VIEs not determined to be a business, on a relative fair value basis to: (i) land, (ii) buildings and improvements, (iii) tenant improvements and identifiable intangible assets such as in-place at-market leases, (iv) acquired above- and below-market ground and tenant leases (including for renewal options), and if applicable (v) assumed debt and (vi) assumed interest rate swaps, based upon comparable sales for land, and the income approach using our estimates of expected future cash flows and other valuation techniques, which include but are not limited to, our estimates of rental rates, revenue growth rates, capitalization rates and discount rates, for other assets and liabilities. We estimate the relative fair values of the tangible assets on an ‘‘as-if-vacant’’ basis. The estimated relative fair value of acquired in-place at-market leases are the estimated costs to lease the property to the occupancy level at the date of acquisition, including the fair value of leasing commissions and legal costs. We evaluate the time period over which we expect such occupancy level to be achieved and include an estimate of the net operating costs (primarily real estate taxes, insurance and utilities) incurred during the lease-up period. Above- and below-market ground and tenant leases are recorded as an asset or liability based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be paid or received pursuant to the in-place ground or tenant leases, respectively, and our estimate of the fair market rental rates for the corresponding in-place leases, over the remaining non-cancelable term of the lease. Assumed debt is recorded at fair value based upon the present value of the expected future payments and current interest rates. See Note 3 for our property acquisition disclosures. Depreciation and Amortization The assets and liabilities listed below are carried on our consolidated balance sheet net of the related accumulated depreciation or amortization/accretion, and any impairment charges. We accelerate depreciation for affected assets when we renovate our buildings or our buildings are impacted by new developments. When assets are sold or retired, their cost and related accumulated depreciation or amortization are removed from our consolidated balance sheet with the resulting gains or losses, if any, reflected in our results of operations for the respective period. • Buildings and improvements are depreciated on a straight-line basis using an estimated life of twenty-five • Tenant improvements are depreciated on a straight-line basis over the life of the related lease, with any remaining balance depreciated in the period of any early lease termination. • Acquired in-place leases are amortized on a straight-line basis over the weighted average remaining term of the acquired in-place leases. • Acquired lease intangibles are amortized on a straight-line basis over the related lease term, with any remaining balance amortized in the period of any early lease termination. • Acquired above- and below-market tenant leases are amortized/accreted on a straight line basis over the life of the related lease and recorded as either an increase (for below-market leases) or a decrease (for above-market leases) to rental revenue. • Acquired above- and below-market ground leases, from which we earn ground rent income, are amortized/accreted on a straight line basis over the life of the related lease and recorded either as an increase (for below-market leases) or a decrease (for above-market leases) to rental revenue. • Acquired above- and below-market ground leases, for which we incur ground rent expense, are accreted/ amortized over the life of the related lease and recorded either as an increase (for below-market leases) or a decrease (for above-market leases) to expense. Real Estate Held for Sale Properties are classified as held for sale in our consolidated balance sheets when they meet certain requirements, including the approval of the sale of the property, the marketing of the property for sale, and our expectation that the sale will likely occur within the next 12 months. Properties classified as held for sale are carried at the lower of their carrying value or fair value less costs to sell, and we also cease to depreciate the property. As of December 31, 2021 and 2020, we did not have any properties held for sale. Dispositions Recognition of gains or losses from sales of investments in real estate requires that we meet certain revenue recognition criteria and transfer control of the real estate to the buyer. The gain or loss recorded is measured as the difference between the sales price, less costs to sell, and the carrying value of the real estate when we sell it. See Note 3 for our property disposition disclosures. Cost capitalization Costs incurred during the period of construction of real estate are capitalized. Cost capitalization of development and redevelopment activities begins during the predevelopment period, which we define as the activities that are necessary to begin the development of the property. We cease capitalization upon substantial completion of the project, but no later than one year from cessation of major construction activity. We also cease capitalization when activities necessary to prepare the property for its intended use have been suspended. Capitalized costs are included in Investment in real estate, gross, in our consolidated balance sheets. Demolition expenses and repairs and maintenance are recorded as expense when incurred. During 2021, 2020 and 2019, we capitalized $185.4 million, $186.4 million and $75.3 million of costs related to our developments, respectively, which included $8.8 million, $4.8 million and $3.8 million of capitalized interest, respectively. Ground Lease We account for our ground lease, for which we are the lessee, in accordance with Topic 842 "Leases". We classify the ground lease as an operating lease, and we recognize a right-of-use asset for the land and a lease liability for the future lease payments. We recognize the lease payments as expense, which is included in Office expenses in our consolidated statements of operations. See Note 4 for more information regarding this ground lease. See Note 14 for the fair value disclosures related to the ground lease liability. Investment in Unconsolidated Fund As of December 31, 2021 and 2020, we managed and owned an equity interest in one unconsolidated Fund. Before November 21, 2019 we managed and owned equity interests in three unconsolidated Funds. See Note 6. We account for our investment in our unconsolidated Fund using the equity method because we have significant influence but not control over the Fund. Under the equity method, we initially recorded our investment in our Fund at cost, which includes acquisition basis difference and additional basis for capital raising costs, and subsequently adjust the investment balance for: (i) our share of the Fund's net income or losses, (ii) our share of the Fund's other comprehensive income or losses, (iii) our cash contributions to the Fund and (iv) our distributions received from the Fund. We will remove our investment in our unconsolidated Fund from our consolidated balance sheet when we sell our interest in the Fund or if the Fund qualifies for consolidation. Our investment in our unconsolidated Fund is included in Investment in unconsolidated Fund in the consolidated balance sheets. Our share of our Fund's accumulated other comprehensive income or losses is included in Accumulated other comprehensive income (loss) in our consolidated balance sheets. As of December 31, 2021 and 2020, the total investment basis difference included in our investment balance in our unconsolidated Fund was $28.7 million and $29.6 million, respectively. Our share of the net income or losses from our Funds is included in Income from unconsolidated Funds in the consolidated statements of operations. We periodically assess whether there has been any impairment that is other than temporary in our investment in our unconsolidated Funds. An impairment charge would be recorded if events or changes in circumstances indicate that a decline in the fair value below the carrying value has occurred and the decline is other-than-temporary. Based upon such periodic assessments, no impairments occurred during 2021, 2020 or 2019. Impairment of Long-Lived Assets We periodically assess whether there has been any impairment in the carrying value of our properties and whenever events or changes in circumstances indicate that the carrying value of a property may not be recoverable. An impairment charge would be recorded if events or changes in circumstances indicate that a decline in the fair value below the carrying value has occurred and the decline is other-than-temporary. Recoverability of the carrying value of our properties is measured by a comparison of the carrying value to the undiscounted future cash flows expected to be generated by the property. If the carrying value exceeds the estimated undiscounted future cash flows, an impairment loss is recorded equal to the difference between the property's carrying value and its fair value based on the estimated discounted future cash flows. Based upon such periodic assessments, no impairments occurred during 2021, 2020 or 2019. Cash and Cash Equivalents We consider short-term investments with maturities of three months or less when purchased to be cash equivalents. Rental Revenues and Tenant Recoveries We account for our rental revenues and tenant recoveries in accordance with Topic 842 "Leases", which we adopted on January 1, 2019 on a modified retrospective basis. We adopted a practical expedient which allows us to account for our rental revenues and tenant recoveries on a combined basis. Rental revenues and tenant recoveries from tenant leases are included in Rental revenues and tenant recoveries in the consolidated statements of operations. All of our tenant leases are classified as operating leases. For lease terms exceeding one year, rental income is recognized on a straight-line basis over the lease term. Tenant receivables consist primarily of amounts due for contractual lease payments and reimbursements of common area maintenance expenses, property taxes, and other costs recoverable from tenants. Deferred rent receivables represent the amount by which the cumulative straight-line rental revenue recorded to date exceeds the cumulative cash rents billed to date under the lease agreement. Rental revenue from month-to-month leases or leases with no scheduled rent increases or other adjustments is recognized on a monthly basis when earned. Lease Terminations Lease termination fees, which are included in Rental revenues and tenant recoveries in the consolidated statements of operations, are recognized on a straight line basis over the new remaining lease term when the related lease is canceled. We recognized lease termination revenue of $1.2 million, $1.0 million and $0.5 million during 2021, 2020 and 2019, respectively. Tenant Improvements Tenant improvements constructed, and owned by us, and reimbursed by tenants are recorded as our assets, and the related revenue, which are included in Rental revenues and tenant recoveries in the consolidated statements of operations, is recognized over the related lease term. We recognized revenue for reimbursement of tenant improvements of $5.8 million, $5.9 million and $5.8 million during 2021, 2020 and 2019, respectively. Tenant Recoveries Estimated tenant recoveries for real estate taxes, common area maintenance and other recoverable operating expenses, which are included in Rental revenues and tenant recoveries in the consolidated statements of operations, are recognized as revenue on a gross basis in the period that the recoverable expenses are incurred. Subsequent to year-end, in accordance with our policy, we perform reconciliations on a lease-by-lease basis and bill or credit each tenant for any differences between the estimated expenses we billed to the tenant and the actual expenses incurred. Collectibility In accordance with Topic 842, we perform an assessment as to whether or not substantially all of the amounts due under a tenant’s lease agreement is deemed probable of collection. This assessment involves using a methodology that requires judgment and estimates about matters that are uncertain at the time the estimates are made, including tenant specific factors, specific industry conditions, and general economic trends and conditions. For leases where we have concluded it is probable that we will collect substantially all the lease payments due under those leases, we continue to record lease income on a straight-line basis over the lease term. For leases where we have concluded that it is not probable that we will collect substantially all the lease payments due under those leases, we limit the lease income to the lesser of the income recognized on a straight-line basis or cash basis. If our conclusion of collectibility changes, we will record the difference between the lease income that would have been recognized on a straight-line basis and cash basis as a current-period adjustment to rental revenues and tenant recoveries. We write-off tenant receivables and deferred rent receivables as a charge against rental revenues and tenant recoveries in the period we conclude that substantially all of the lease payments are not probable of collection. If we subsequently collect amounts that were previously written off then the amounts collected are recorded as an increase to our rental revenues and tenant recoveries in the period they are collected. Charges for uncollectible tenant receivables and deferred rent receivables, which were primarily due to the impact of the COVID-19 pandemic, reduced our office revenues by $3.0 million and $41.0 million in 2021 and 2020, respectively. Lease Modifications In April 2020, the FASB staff issued a question and answer document (the “Lease Modification Q&A”) on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. Under the existing lease accounting guidance, we would be required to determine on a lease-by-lease basis if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows us, if certain criteria are met, to bypass the lease-by-lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. We have availed ourselves of the election to avoid performing a lease-by-lease analysis and we have elected to apply the lease modification accounting framework for the lease concessions that meet the criteria. Office Parking Revenues Office parking revenues, which are included in office Parking and other income in our consolidated statements of operations, are within the scope of Topic 606 "Revenue from Contracts with Customers". Our lease contracts generally make a specified number of parking spaces available to the tenant, and we bill and recognize parking revenues on a monthly basis in accordance with the lease agreements, generally using the monthly parking rates in effect at the time of billing. Office parking revenues were $69.0 million, $76.1 million and $108.7 million in 2021, 2020 and 2019, respectively. Office parking receivables were $0.8 million and $0.6 million as of December 31, 2021 and 2020, respectively, and are included in Tenant receivables in our consolidated balance sheets. Insurance Recoveries The amount by which insurance recoveries related to property damage exceeds any losses recognized from that damage are recorded as other income when payment has been received or confirmation of the amount of proceeds has been received. In January 2020, there was a fire in one of our residential property buildings. We carry comprehensive liability and property insurance covering all of the properties in our portfolio under blanket insurance policies to cover these kinds of losses. We recorded $4.8 million and $3.9 million of business interruption revenues during 2021 and 2020, respectively, which is included in Multifamily rental - Parking and other income in the consolidated statements of operations. In addition, we recorded a gain related to property damage of $13.1 million during 2020, which is included in Other income in the consolidated statements of operations. Interest Income Interest income from our short-term money market fund investments is recognized on an accrual basis. Interest income is included in other income in the consolidated statements of operations. Leasing Costs We account for our leasing costs in accordance with Topic 842 "Leases", which we adopted on January 1, 2019 on a modified retrospective basis. In accordance with Topic 842, we capitalize initial direct costs of a lease, which are costs that would not have been incurred had the lease not been executed. Costs to negotiate a lease that would have been incurred regardless of whether the lease was executed, such as employee salaries, are not considered to be initial direct costs, and are expensed as incurred. Loan Costs Loan costs incurred directly with the issuance of secured notes payable and revolving credit facilities are deferred and amortized to interest expense over the respective loan or credit facility term. Any unamortized amounts are written off upon early repayment of the secured notes payable, and the related cost and accumulated amortization are removed from our consolidated balance sheets. To the extent that a refinancing is considered an exchange of debt with the same lender, we account for loan costs based upon whether the old debt is determined to be modified or extinguished for accounting purposes. If the old debt is determined to be modified then we (i) continue to defer and amortize any unamortized deferred loan costs associated with the old debt at the time of the modification over the new term of the modified debt, (ii) defer and amortize the lender costs incurred in connection with the modification over the new term of the modified debt, and (iii) expense all other costs associated with the modification. If the old debt is determined to be extinguished then we (i) write off any unamortized deferred loan costs associated with the extinguished debt at the time of the extinguishment and remove the related cost and accumulated amortization from our balance sheet, (ii) expense all lender costs associated with the extinguishment, and (iii) defer and amortize all other costs incurred directly in connection with the extinguishment over the term of the new debt. In circumstances where we modify or exchange our revolving credit facility with the same lender, we account for the loan costs based upon whether the borrowing capacity of the new arrangement is (a) equal to or greater than the borrowing capacity of the old arrangement, or (b) less than the borrowing capacity of the old arrangement (borrowing capacity is defined as the product of the remaining term and the maximum available credit). If the borrowing capacity of the new arrangement is greater than or equal to the borrowing capacity of the old arrangement, then we (i) continue to defer and amortize the unamortized deferred loan costs from the old arrangement over the term of the new arrangement and (ii) defer all lender and other costs incurred directly in connection with the new arrangement over the term of the new arrangement. If the borrowing capacity of the new arrangement is less than the borrowing capacity of the old arrangement, then we (i) write off any unamortized deferred loan costs at the time of the transaction related to the old arrangement in proportion to the decrease in the borrowing capacity of the old arrangement and (ii) defer all lender and other costs incurred directly in connection with the new arrangement over the term of the new arrangement. Deferred loan costs are presented on the balance sheet as a deduction from the carrying amount of our secured notes payable and revolving credit facility. All loan costs expensed and deferred loan costs amortized are included in interest expense in our consolidated statements of operations. See Note 8 for our loan cost disclosures. Debt Discounts and Premiums Debt discounts and premiums related to recording debt assumed in connection with property acquisitions at fair value are generally amortized and accreted, respectively, over the remaining term of the related loan, which approximates the effective interest method. The amortization/accretion is included in interest expense in our consolidated statements of operations. Derivative Contracts We make use of interest rate swap contracts to manage the risk associated with changes in interest rates on our floating-rate debt. When we enter into a floating-rate term loan, we generally enter into an interest rate swap agreement for the equivalent principal amount, for a period covering the majority of the loan term, which effectively converts our floating-rate debt to a fixed-rate basis during that time. We do not speculate in derivatives and we do not make use of any other derivative instruments. When entering into derivative agreements, we generally elect to designate them as cash flow hedges for accounting purposes. Changes in fair value of hedging instruments designated as cash flow hedges are recorded in accumulated other comprehensive income (loss) (AOCI), which is a component of equity outside of earnings. For our Funds' hedging instruments designated as cash flow hedges, we record our share of the changes in fair value of the hedging instrument in AOCI. Amounts recorded in AOCI related to our designated hedges are reclassified to Interest expense as interest payments are made on the hedged floating rate debt. Amounts reported in AOCI related to our Funds' hedges are reclassified to Income from unconsolidated Funds, as interest payments are made by our Funds on their hedged floating rate debt. We present our derivatives on the balance sheet at fair value on a gross basis. Our share of the fair value of our Funds' derivatives is included in our investment in unconsolidated Funds on our consolidated balance sheet. See Note 10 for our derivative disclosures. Stock-Based Compensation We account for stock-based compensation, which includes grants of LTIP Units, using the fair value method of accounting. The estimated fair value of LTIP Units granted, net of estimated forfeitures, is amortized over the vesting period, which is based upon service. See Note 13 for our stock-based compensation disclosures. EPS We calculate basic EPS by dividing the net income attributable to common stockholders for the period by the weighted average number of common shares outstanding during the respective period. We calculate diluted EPS by dividing the net income attributable to common stockholders for the period by the weighted average number of common shares and dilutive instruments outstanding during the respective period using the treasury stock method. Unvested LTIP Units contain non-forfeitable rights to dividends and we account for them as participating securities and include them in the computation of basic and diluted EPS using the two-class method. See Note 12 for our EPS disclosures. Segment Information Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate two business segments: the acquisition, development, ownership and management of office real estate, and the acquisition, development, ownership and management of multifamily real estate. The services for our office segment include primarily rental of office space and other tenant services, including parking and storage space rental. The services for our multifamily segment include primarily rental of apartments and other tenant services, including parking and storage space rental. See Note 15 for our segment disclosures. Income Taxes We have elected to be taxed as a REIT under the Code, commencing with our initial taxable year ended December 31, 2006. To qualify as a REIT, we are required (among other things) to distribute at least 90% of our REIT taxable income to our stockholders and meet various other requirements imposed by the Code relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided that we qualify for taxation as a REIT, we are generally not subject to corporate-level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. If we fail to qualify as a REIT in any taxable year, and are unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at the regular corporate rate, including any applicable alternative minimum tax for taxable years prior to 2018. We have elected to treat one of our subsidiaries as a TRS, which generally may engage in any business, including the provision of customary or non-customary services to our tenants. A TRS is treated as a regular corporation and is subject to federal income tax and applicable state income and franchise taxes at regular corporate rates. We had two TRSs in 2020 and 2019. Our TRSs did not have significant tax provisions or deferred income tax items for 2021, 2020 or 2019. Our subsidiaries (other than our TRS), including our Operating Partnership, are partnerships, disregarded entities, QRSs or REITs, as applicable, for federal income tax purposes. Under applicable federal and state income tax rules, the allocated share of net income or loss from disregarded entities or flow-through entities is reportable in the income tax returns of the respective owners. Accordingly, no income tax provision is included in our consolidated financial statements for these entities. New Accounting Pronouncements Changes to US GAAP are implemented by the FASB in the form of ASUs. We consider the applicability and impact of all ASUs. We did not adopt any ASUs during 2021, and as of the date of this Report, the FASB has not issued any ASUs that we expect to be applicable and have a material impact on our future consolidated financial statements.

The property sold was held by one of our consolidated JVs in which we owned a two-thirds capital interest. The JV was subsequently dissolved prior to December 31, 2020. 2019 Property Acquisition and JV consolidation Acquisition of The Glendon On June 7, 2019, we acquired The Glendon, a residential community in Westwood, and on June 28, 2019, we contributed the property to a consolidated JV that we manage and in which we own a 20% capital interest. The table below summarizes the purchase price allocation for the acquisition. The contract and purchase prices differ due to prorations and similar adjustments: (In thousands, except number of units) The Glendon Submarket West Los Angeles Acquisition date June 7, 2019 Contract price $ 365,100 Number of multifamily units 350 Retail square footage 50 Land $ 32,773 Buildings and improvements 333,624 Tenant improvements and lease intangibles 2,301 Acquired above- and below-market leases, net (2,114) Net assets and liabilities acquired $ 366,584 Consolidation of JV On November 21, 2019, we acquired an additional 16.3% of the equity in one of our previously unconsolidated Funds, Fund X, in exchange for $76.9 million in cash and 332 thousand OP Units valued at $14.4 million, which increased our ownership in the Fund to 89.0%. In connection with this transaction, we restructured the Fund with one remaining institutional investor. The new JV is a VIE, and as a result of the amended operating agreement, we became the primary beneficiary of the VIE and commenced consolidating the JV on November 21, 2019. The results of the consolidated JV are included in our operating results from November 21, 2019 (before November 21, 2019, our share of the Fund's net income was included in our statements of operations in Income from unconsolidated Funds). The consolidation of the JV required us to recognize the JVs identifiable assets and liabilities at fair value in our consolidated financial statements, along with the fair value of the non-controlling interest of $61.4 million. We recognized a gain of $307.9 million to adjust the carrying value of our existing investment in the JV to its estimated fair value upon consolidation. The gain was determined by taking the difference between: (a) the fair value of Fund X’s assets less its liabilities and (b) the sum of the fair value of the noncontrolling interest, carrying value of our existing investment in Fund X, and the amounts paid to acquire other Fund investors’ interests. We determined the fair value of Fund X’s assets and liabilities upon initial consolidation using our estimates of expected future cash flows and other valuation techniques. We estimated the fair values of Fund X’s properties by using the income and sales comparison valuation approaches which included, but are not limited to, our estimates of rental rates, comparable sales, revenue growth rates, capitalization rates and discount rates. Assumed debt was recorded at fair value based upon the present value of the expected future payments and current interest rates. Other acquired assets, including cash and assumed liabilities were recorded at cost due to the short-term nature of the balances. The JV owns six Class A office properties totaling 1.5 million square feet in the Los Angeles submarkets of Beverly Hills, Santa Monica, Sherman Oaks/Encino and Warner Center. The JV also owns an interest of 9.4% in our remaining unconsolidated Fund, Partnership X, which owns two additional Class A office properties totaling 386,000 square feet in Beverly Hills and Brentwood.

Real Estate Investments, Net [Abstract]
Investments in Unconsolidated Funds	Investments in Unconsolidated Funds Description of our Funds As of December 31, 2021 and 2020, we managed and owned an equity interest of 33.5% in an unconsolidated Fund, Partnership X, through which we and other investors in the Fund owned two office properties totaling 0.4 million square feet. We purchased an additional interest of 3.6% in Partnership X for $6.6 million during 2020. Before November 21, 2019, we managed and owned equity interests in three unconsolidated Funds, consisting of 6.2% of the Opportunity Fund, 72.7% of Fund X and 28.4% of Partnership X, through which we and other investors in the Funds owned eight office properties totaling 1.8 million square feet. On November 21, 2019, we acquired additional interests of 16.3% in Fund X and 1.5% in Partnership X, and restructured Fund X which resulted in Fund X being treated as a consolidated JV from November 21, 2019. See Note 3 for more information regarding the consolidation of the JV. We also acquired all of the investors’ ownership interests in the Opportunity Fund (The Opportunity Fund’s only investment was an ownership interest in Fund X) and closed the Opportunity Fund. During the period January 1, 2019 to November 20, 2019 we purchased additional interests of 1.4% in Fund X and 3.9% in Partnership X. Our Funds pay us fees and reimburse us for certain expenses related to property management and other services we provide, which are included in Other income in our consolidated statements of operations.

Derivative Contracts	Derivative Contracts Derivative Summary As of December 31, 2021, all of our interest rate swaps, including our consolidated JVs' and our unconsolidated Fund's interest rate swaps, as summarized below, were designated as cash flow hedges: Number of Interest Rate Swaps Notional Consolidated derivatives (1)(2)(4)(5) 37 $ 5,317,400 Unconsolidated Fund's derivatives (3)(4)(5) 2 $ 115,000 ___________________________________________________ (1) The notional amount reflects 100%, not our pro-rata share, of our consolidated JVs' derivatives. (2) The notional amount includes: a. Two swaps with a combined initial notional amount of $50.0 million, which will increase to $450.0 million on July 1, 2022 to replace existing swaps when they expire, and b. One swap with a notional amount of $300.0 million that will replace existing swaps when they expire on January 1, 2022. (3) The notional amount reflects 100%, not our pro-rata share, of our unconsolidated Fund's derivatives. For more information about our Fund, including our equity interest percentage, see Note 6 . (4) Our derivative contracts do not provide for right of offset between derivative contracts. (5) See Note 14 for our derivative fair value disclosures. Credit-risk-related Contingent Features Our swaps include credit-risk related contingent features. For example, we have agreements with certain of our interest rate swap counterparties that contain a provision under which we could be declared in default on our derivative obligations if repayment of the underlying indebtedness that we are hedging is accelerated by the lender due to our default on the indebtedness. As of December 31, 2021, there have been no events of default with respect to our interest rate swaps, our consolidated JVs' interest rate swaps, or our Fund's interest rate swaps. We do not post collateral for our interest rate swap contract liabilities. The fair value of our interest rate swap contract liabilities, including accrued interest and excluding credit risk adjustments, was as follows: (In thousands) December 31, 2021 December 31, 2020 Consolidated derivatives (1) $ 77,760 $ 225,166 Unconsolidated Fund's derivatives (2) $ — $ 208 ___________________________________________________ (1) Includes 100%, not our pro-rata share, of our consolidated JVs' derivatives. (2) The amounts reflect 100%, not our pro-rata share, of our unconsolidated Fund's derivatives. For more information about our Fund, including our equity interest percentage, see Note 6. Counterparty Credit Risk We are subject to credit risk from the counterparties on our interest rate swap contract assets because we do not receive collateral. We seek to minimize that risk by entering into agreements with a variety of high quality counterparties with investment grade ratings. The fair value of our interest rate swap contract assets, including accrued interest and excluding credit risk adjustments, was as follows: (In thousands) December 31, 2021 December 31, 2020 Consolidated derivatives (1)(3) $ 14,927 $ — Unconsolidated Fund's derivatives (2)(3) $ 1,889 $ — ___________________________________________________ (1) Includes 100%, not our pro-rata share, of our consolidated JVs' derivatives. (2) The amounts reflect 100%, not our pro-rata share, of our unconsolidated Fund's derivatives. For more information about our Fund, including our equity interest percentage, see Note 6. (3) We did not have any interest rate swap contract asset balances as of December 31, 2020.

Stockholders' Equity Note [Abstract]
Equity	Equity Transactions During 2021: • We acquired 65 thousand OP Units in exchange for issuing an equal number of shares of our common stock to the holders of the OP Units. • We acquired 4,051 OP Units for $122 thousand in cash. During 2020: • We acquired 94 thousand OP Units in exchange for issuing an equal number of shares of our common stock to the holders of the OP Units. • We acquired 150 OP Units for $7 thousand in cash. During 2019: • We acquired 222 thousand OP Units in exchange for issuing an equal number of shares of our common stock to the holders of the OP Units. • We acquired 19 thousand OP Units and fully-vested LTIP Units for $734 thousand in cash. • We issued 4.9 million shares of our common stock under our ATM program for net proceeds of $201.0 million. • We purchased a property on June 7, 2019 for a contract price of $365.1 million, which we subsequently contributed to one of our consolidated JVs on June 28, 2019. We manage and own a twenty percent capital interest in the JV. The acquisition and related working capital was funded with (i) a secured, non-recourse $160.0 million interest-only loan scheduled to mature in June 2029, which was assumed by the consolidated JV to which we contributed the property, (ii) a $44.0 million capital contribution by us to the JV, and (iii) a $176.0 million capital contribution by Noncontrolling interests in the JV. See Note 3 for more information regarding the property acquisition and Note 8 for more information regarding the loan. • On November 21, 2019, we acquired an additional 16.3% of the equity in one of our previously unconsolidated Funds, Fund X, in exchange for $76.9 million in cash and 332 thousand OP Units valued at $14.4 million, which increased our ownership in the Fund to 89.0%. See Note 3 for more information regarding the consolidation of the JV and note 6 for more information regarding our Funds. Noncontrolling Interests Our noncontrolling interests consist of interests in our Operating Partnership and consolidated JVs which are not owned by us. As of December 31, 2021, noncontrolling interests in our Operating Partnership owned 31.1 million OP Units and fully-vested LTIP Units, which represented approximately 15.0% of our Operating Partnership's total outstanding interests, and we owned 175.5 million OP Units (to match our 175.5 million shares of outstanding common stock). A share of our common stock, an OP Unit and an LTIP Unit (once vested and booked up) have essentially the same economic characteristics, sharing equally in the distributions from our Operating Partnership. Investors who own OP Units have the right to cause our Operating Partnership to acquire their OP Units for an amount of cash per unit equal to the market value of one share of our common stock at the date of acquisition, or, at our election, exchange their OP Units for shares of our common stock on a one-for-one b asis. LTIP Units have been granted to our employees and non-employee directors as part of their compensation. These awards generally vest over a service period and once vested can generally be converted to OP Units provided our stock price increases by more than a specified hurdle.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Stock Incentive Plans The Douglas Emmett, Inc. 2016 Omnibus Stock Incentive Plan, as amended, our stock incentive plan (our "2016 Plan"), permits us to make grants of incentive stock options, non-qualified stock options, stock appreciation rights, deferred stock awards, restricted stock awards, dividend equivalent rights and other stock-based awards. On May 28, 2020, our stockholders approved an amendment to the 2016 Plan to, among other things, increase the number of common shares for future awards by 9.5 million. We had an aggregate of 6.9 million shares available for grant as of December 31, 2021. Awards such as LTIP Units, deferred stock and restricted stock, which deliver the full value of the underlying shares, are counted against the Plan limits as two shares. Awards such as stock options and stock appreciation rights are counted as one share. The number of shares reserved under our 2016 Plan is also subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization. Shares of stock underlying any awards that are forfeited, canceled or otherwise terminated (other than by exercise) are added back to the shares of stock available for future issuance under the 2016 Plan. For options exercised, our policy is to issue common stock on a net settlement basis - net of the exercise price and related taxes. Until it expired in 2016, we made grants under our 2006 Omnibus Stock Incentive Plan (our "2006 Plan"), which was substantially similar to our 2016 Plan. No further awards may be granted under our 2006 Plan, although awards granted under the 2006 Plan in the past and which are still outstanding will continue to be governed by the terms of our 2006 Plan. Our 2016 and 2006 Plans (the "Plans") are administered by the compensation committee of our board of directors. The compensation committee may interpret our Plans and make all determinations necessary or desirable for the administration of our Plans. The committee has full power and authority to select the participants to whom awards will be granted, to make any combination of awards to participants, to accelerate the exercisability or vesting of any award and to determine the specific terms and conditions of each award, subject to the provisions of our Plans. All officers, employees, directors and other key personnel (including consultants and prospective employees) are eligible to participate in our 2016 Plan. We have made certain awards in the form of a separate series of units of limited partnership interests in our Operating Partnership called LTIP Units, which can be granted either as free-standing awards or in tandem with other awards under our 2016 Plan. Our LTIP Units are valued by reference to the value of our common stock at the time of grant, and are subject to such conditions and restrictions as the compensation committee may determine, including continued employment or service, and/or achievement of pre-established performance goals, financial metrics and other objectives. Once vested, LTIP Units can generally be converted to OP Units on a one for one basis, provided our stock price increases by more than a specified hurdle. Employee Awards We grant stock-based compensation in the form of LTIP Units as a part of our annual incentive compensation to various employees each year, a portion which vests at the date of grant, and the remainder which vests in three equal annual installments over the three calendar years following the grant date. Compensation expense for LTIP Units which are not vested at the grant date is recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award. We have also made long-term grants in the form of LTIP Units to certain employees, which generally vest in equal annual installments over four five Non-Employee Director Awards As annual fees for their services, each of our non-employee directors receives a grant of LTIP Units that vests on a quarterly basis during the year the services are rendered, which is the calendar year following the grant date. In aggregate, we granted 52 thousand, 55 thousand, and 38 thousand LTIP Units to our non-employee directors during 2021, 2020 and 2019, respectively. Compensation Expense At December 31, 2021, the total unrecognized stock-based compensation expense for unvested LTIP Unit awards was $19.5 million, which will be recognized over a weighted-average term of 2 years.

Fair Value of Financial Instruments	Fair Value of Financial Instruments Our estimates of the fair value of financial instruments were determined using available market information and widely used valuation methods. Considerable judgment is necessary to interpret market data and determine an estimated fair value. The use of different market assumptions or valuation methods may have a material effect on the estimated fair values. The FASB fair value framework hierarchy distinguishes between assumptions based on market data obtained from sources independent of the reporting entity, and the reporting entity’s own assumptions about market-based inputs. The hierarchy is as follows: Level 1 - inputs utilize unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 - inputs are observable either directly or indirectly for similar assets and liabilities in active markets. Level 3 - inputs are unobservable assumptions generated by the reporting entity As of December 31, 2021, we did not have any fair value estimates of financial instruments using Level 3 inputs. Financial instruments disclosed at fair value Short term financial instruments The carrying amounts for cash and cash equivalents, tenant receivables, revolving credit line, interest payable, accounts payable, security deposits and dividends payable approximate fair value because of the short-term nature of these instruments. Secured notes payable See Note 8 for the details of our secured notes payable. We estimate the fair value of our consolidated secured notes payable by calculating the credit-adjusted present value of the principal and interest payments for each secured note payable. The calculation incorporates observable market interest rates which we consider to be Level 2 inputs, assumes that the loans will be outstanding through maturity, and includes any maturity extension options. The table below presents the estimated fair value and carrying value of our secured notes payable (excluding our revolving credit facility), the carrying value includes unamortized loan premium and excludes unamortized deferred loan fees: (In thousands) December 31, 2021 December 31, 2020 Fair value $ 5,017,494 $ 4,719,462 Carrying value $ 5,050,732 $ 4,706,979 Ground lease liability See Note 4 for the details of our ground lease. We estimate the fair value of our ground lease liability by calculating the present value of the future lease payments disclosed in Note 4 using our incremental borrowing rate. The calculation incorporates observable market interest rates which we consider to be Level 2 inputs. The table below presents the estimated fair value and carrying value of our ground lease liability: (In thousands) December 31, 2021 December 31, 2020 Fair value $ 8,861 $ 11,865 Carrying value $ 10,860 $ 10,871 Financial instruments measured at fair value Derivative instruments See Note 10 for the details of our derivatives. We present our derivatives in the consolidated balance sheets at fair value, on a gross basis, excluding accrued interest. We estimate the fair value of our derivative instruments by calculating the credit-adjusted present value of the expected future cash flows of each derivative. The calculation incorporates the contractual terms of the derivatives, observable market interest rates which we consider to be Level 2 inputs, and credit risk adjustments to reflect the counterparty's as well as our own nonperformance risk. Our derivatives are not subject to master netting arrangements. The table below presents the estimated fair value of our derivatives: (In thousands) December 31, 2021 December 31, 2020 Derivative Assets: Fair value - c onsolidated derivatives (1) $ 15,473 $ — Fair value - unconsolidated Fund's derivatives (2) $ 1,963 $ — Derivative Liabilities: Fair value - c onsolidated derivatives (1) $ 69,930 $ 214,016 Fair value - unconsolidated Fund's derivatives (2) $ — $ 137 ___________________________________________________________________________________ (1) Consolidated derivatives, which include 100%, not our pro-rata share, of our consolidated JVs' derivatives, are included in interest rate contracts in our consolidated balance sheets. The fair values exclude accrued interest which is included in interest payable in the consolidated balance sheets. (2) The amounts reflect 100%, not our pro-rata share, of our unconsolidated Fund's derivatives. Our pro-rata share of the amounts related to the unconsolidated Fund's derivatives is included in our Investment in unconsolidated Fund in our consolidated balance sheets. See Note 6 for more information about our Fund, including our equity interest percentage, and see "Guarantees" in Note 17 regarding our Fund's derivatives.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate in two business segments: (i) the acquisition, development, ownership and management of office real estate and (ii) the acquisition, development, ownership and management of multifamily real estate. The services for our office segment primarily include rental of office space and other tenant services, including parking and storage space rental. The services for our multifamily segment include rental of apartments and other tenant services, including parking and storage space rental. Asset information by segment is not reported because we do not use this measure to assess performance or make decisions to allocate resources. Therefore, depreciation and amortization expense is not allocated among segments. General and administrative expenses and interest expense are not included in segment profit as our internal reporting addresses these items on a corporate level. The table below presents the operating activity of our reportable segments: (In thousands) Year Ended December 31, 2021 2020 2019 Office Segment Total office revenues $ 786,870 $ 771,169 $ 816,755 Office expenses (265,376) (268,259) (264,482) Office segment profit 521,494 502,910 552,273 Multifamily Segment Total multifamily revenues 131,527 120,354 119,927 Multifamily expenses (38,025) (37,154) (33,681) Multifamily segment profit 93,502 83,200 86,246 Total profit from all segments $ 614,996 $ 586,110 $ 638,519 The table below presents a reconciliation of the total profit from all segments to net income attributable to common stockholders: (In thousands) Year Ended December 31, 2021 2020 2019 Total profit from all segments $ 614,996 $ 586,110 $ 638,519 General and administrative expenses (42,554) (39,601) (38,068) Depreciation and amortization (371,289) (385,248) (357,743) Other income 2,465 16,288 11,653 Other expenses (937) (2,947) (7,216) Income from unconsolidated Funds 946 430 6,923 Interest expense (147,496) (142,872) (143,308) Gain on sale of investment in real estate — 6,393 — Gain from consolidation of JV — — 307,938 Net income 56,131 38,553 418,698 Less: Net loss (income) attributable to noncontrolling interests 9,136 11,868 (54,985) Net income attributable to common stockholders $ 65,267 $ 50,421 $ 363,713

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees Legal Proceedings From time to time, we are party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of our business. Excluding ordinary, routine litigation incidental to our business, we are not currently a party to any legal proceedings that we believe would reasonably be expected to have a materially adverse effect on our business, financial condition or results of operations. Concentration of Risk Tenant Receivables We are subject to credit risk with respect to our tenant receivables and deferred rent receivables related to our tenant leases. Our tenants' ability to honor the terms of their respective leases remains dependent upon economic, regulatory and social factors. We seek to minimize our credit risk from our tenant leases by: (i) targeting smaller, more affluent office tenants, from a diverse mix of industries, (ii) performing credit evaluations of prospective tenants, and (iii) obtaining security deposits or letters of credit from our tenants. During 2021, 2020 and 2019, no tenant accounted for more than 10% of our total revenues. See our "Rental Revenues and Tenant Recoveries" accounting policy in Note 2 for the charges to revenue for uncollectible amounts for tenant receivables and deferred rent receivables. Geographic Risk All of our properties, including the properties of our consolidated JVs and our unconsolidated Fund, are located in Los Angeles County, California and Honolulu, Hawaii, and we are therefore susceptible to adverse economic and regulatory developments, as well as natural disasters, in those markets. Swap Counterparty Credit Risk We are subject to credit risk with respect to our interest rate swap counterparties that we use to manage the risk associated with our floating rate debt. We do not post or receive collateral with respect to our swap transactions. Our swap contracts do not provide for right of offset between derivative contracts. See Note 10 for the details of our interest rate contracts. We seek to minimize our credit risk by entering into agreements with a variety of counterparties with investment grade ratings. Cash Balances We have significant cash balances invested in a variety of short-term money market funds that are intended to preserve principal value and maintain a high degree of liquidity while providing current income. These investments are not insured against loss of principal and there is no guarantee that our investments in these funds will be redeemable at par value. We also have significant cash balances in bank accounts with high quality financial institutions with investment grade ratings. Interest bearing bank accounts at each U.S. banking institution are insured by the FDIC up to $250 thousand. Asset Retirement Obligations Conditional asset retirement obligations represent a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement is conditional on a future event that may or may not be within our control. A liability for a conditional asset retirement obligation must be recorded if the fair value of the obligation can be reasonably estimated. Environmental site assessments have identified thirty-two buildings in our Consolidated Portfolio which contain asbestos, and would have to be removed in compliance with applicable environmental regulations if these properties are demolished or undergo major renovations. As of December 31, 2021, the obligations to remove the asbestos from properties which are currently undergoing major renovations, or that we plan to renovate in the future, are not material to our consolidated financial statements. As of December 31, 2021, the obligations to remove the asbestos from our other properties have indeterminable settlement dates, and we are unable to reasonably estimate the fair value of the associated conditional asset retirement obligations. Contractual Commitments Development Projects In West Los Angeles, we are building a high-rise apartment building with 376 apartments. In downtown Honolulu, we are converting a 25 story, 493,000 square foot office tower into approximately 493 apartments in phases over a number of years as the office space is vacated. As of December 31, 2021, we had an aggregate remaining contractual commitment for these and other development projects of approximately $69.7 million. Other Contractual Commitments As of December 31, 2021, we had an aggregate remaining contractual commitment for repositionings, capital expenditure projects and tenant improvements of approximately $22.0 million. Guarantees Partnership X Guarantees Our unconsolidated Fund, Partnership X, has a $115.0 million floating-rate term loan that matures on September 14, 2028. Starting on October 1, 2021, the loan carried interest at LIBOR + 1.35% (with a zero-percent LIBOR floor), which has been effectively fixed at 2.19% until October 1, 2026 with interest rate swaps (which do not have zero-percent LIBOR floors). The loan is secured by two properties held by Partnership X and is non-recourse. We have made certain environmental and other limited indemnities and guarantees covering customary non-recourse carve-outs for Partnership X's loan, and we have also guaranteed the related swaps. Partnership X has agreed to indemnify us for any amounts that we would be required to pay under these agreements. As of December 31, 2021, assuming that LIBOR does not decrease below zero-percent, the maximum future interest payments for the swap were $4.7 million.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with US GAAP requires management to make certain estimates that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.
Acquisitions and Initial Consolidation of VIEs	Acquisitions and Initial Consolidation of VIEs We account for property acquisitions as asset acquisitions, and include the acquired properties' results of operations in our results of operations from the respective acquisition date. We allocate the purchase price for asset acquisitions, which includes the capitalized transaction costs, and for the properties upon the initial consolidation of VIEs not determined to be a business, on a relative fair value basis to: (i) land, (ii) buildings and improvements, (iii) tenant improvements and identifiable intangible assets such as in-place at-market leases, (iv) acquired above- and below-market ground and tenant leases (including for renewal options), and if applicable (v) assumed debt and (vi) assumed interest rate swaps, based upon comparable sales for land, and the income approach using our estimates of expected future cash flows and other valuation techniques, which include but are not limited to, our estimates of rental rates, revenue growth rates, capitalization rates and discount rates, for other assets and liabilities. We estimate the relative fair values of the tangible assets on an ‘‘as-if-vacant’’ basis. The estimated relative fair value of acquired in-place at-market leases are the estimated costs to lease the property to the occupancy level at the date of acquisition, including the fair value of leasing commissions and legal costs. We evaluate the time period over which we expect such occupancy level to be achieved and include an estimate of the net operating costs (primarily real estate taxes, insurance and utilities) incurred during the lease-up period. Above- and below-market ground and tenant leases are recorded as an asset or liability based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be paid or received pursuant to the in-place ground or tenant leases, respectively, and our estimate of the fair market rental rates for the corresponding in-place leases, over the remaining non-cancelable term of the lease. Assumed debt is recorded at fair value based upon the present value of the expected future payments and current interest rates. See Note 3 for our property acquisition disclosures.
Depreciation and Amortization	Depreciation and Amortization The assets and liabilities listed below are carried on our consolidated balance sheet net of the related accumulated depreciation or amortization/accretion, and any impairment charges. We accelerate depreciation for affected assets when we renovate our buildings or our buildings are impacted by new developments. When assets are sold or retired, their cost and related accumulated depreciation or amortization are removed from our consolidated balance sheet with the resulting gains or losses, if any, reflected in our results of operations for the respective period. • Buildings and improvements are depreciated on a straight-line basis using an estimated life of twenty-five • Tenant improvements are depreciated on a straight-line basis over the life of the related lease, with any remaining balance depreciated in the period of any early lease termination. • Acquired in-place leases are amortized on a straight-line basis over the weighted average remaining term of the acquired in-place leases. • Acquired lease intangibles are amortized on a straight-line basis over the related lease term, with any remaining balance amortized in the period of any early lease termination. • Acquired above- and below-market tenant leases are amortized/accreted on a straight line basis over the life of the related lease and recorded as either an increase (for below-market leases) or a decrease (for above-market leases) to rental revenue. • Acquired above- and below-market ground leases, from which we earn ground rent income, are amortized/accreted on a straight line basis over the life of the related lease and recorded either as an increase (for below-market leases) or a decrease (for above-market leases) to rental revenue. • Acquired above- and below-market ground leases, for which we incur ground rent expense, are accreted/ amortized over the life of the related lease and recorded either as an increase (for below-market leases) or a decrease (for above-market leases) to expense.
Real Estate Held for Sale	Real Estate Held for SaleProperties are classified as held for sale in our consolidated balance sheets when they meet certain requirements, including the approval of the sale of the property, the marketing of the property for sale, and our expectation that the sale will likely occur within the next 12 months. Properties classified as held for sale are carried at the lower of their carrying value or fair value less costs to sell, and we also cease to depreciate the property.
Dispositions	Dispositions Recognition of gains or losses from sales of investments in real estate requires that we meet certain revenue recognition criteria and transfer control of the real estate to the buyer. The gain or loss recorded is measured as the difference between the sales price, less costs to sell, and the carrying value of the real estate when we sell it. See Note 3 for our property disposition disclosures.
Cost capitalization	Cost capitalizationCosts incurred during the period of construction of real estate are capitalized. Cost capitalization of development and redevelopment activities begins during the predevelopment period, which we define as the activities that are necessary to begin the development of the property.  We cease capitalization upon substantial completion of the project, but no later than one year from cessation of major construction activity.  We also cease capitalization when activities necessary to prepare the property for its intended use have been suspended. Capitalized costs are included in Investment in real estate, gross, in our consolidated balance sheets. Demolition expenses and repairs and maintenance are recorded as expense when incurred.
Ground Leases	Ground LeaseWe account for our ground lease, for which we are the lessee, in accordance with Topic 842 "Leases". We classify the ground lease as an operating lease, and we recognize a right-of-use asset for the land and a lease liability for the future lease payments. We recognize the lease payments as expense, which is included in Office expenses in our consolidated statements of operations.
Investment in Unconsolidated Funds	Investment in Unconsolidated Fund As of December 31, 2021 and 2020, we managed and owned an equity interest in one unconsolidated Fund. Before November 21, 2019 we managed and owned equity interests in three unconsolidated Funds. See Note 6.
Impairment of Long-Lived Assets	Impairment of Long-Lived AssetsWe periodically assess whether there has been any impairment in the carrying value of our properties and whenever events or changes in circumstances indicate that the carrying value of a property may not be recoverable. An impairment charge would be recorded if events or changes in circumstances indicate that a decline in the fair value below the carrying value has occurred and the decline is other-than-temporary. Recoverability of the carrying value of our properties is measured by a comparison of the carrying value to the undiscounted future cash flows expected to be generated by the property. If the carrying value exceeds the estimated undiscounted future cash flows, an impairment loss is recorded equal to the difference between the property's carrying value and its fair value based on the estimated discounted future cash flows.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider short-term investments with maturities of three months or less when purchased to be cash equivalents.
Rental Revenue and Tenant Recoveries	Rental Revenues and Tenant Recoveries We account for our rental revenues and tenant recoveries in accordance with Topic 842 "Leases", which we adopted on January 1, 2019 on a modified retrospective basis. We adopted a practical expedient which allows us to account for our rental revenues and tenant recoveries on a combined basis. Rental revenues and tenant recoveries from tenant leases are included in Rental revenues and tenant recoveries in the consolidated statements of operations. All of our tenant leases are classified as operating leases. For lease terms exceeding one year, rental income is recognized on a straight-line basis over the lease term. Tenant receivables consist primarily of amounts due for contractual lease payments and reimbursements of common area maintenance expenses, property taxes, and other costs recoverable from tenants. Deferred rent receivables represent the amount by which the cumulative straight-line rental revenue recorded to date exceeds the cumulative cash rents billed to date under the lease agreement. Rental revenue from month-to-month leases or leases with no scheduled rent increases or other adjustments is recognized on a monthly basis when earned. Lease Terminations Lease termination fees, which are included in Rental revenues and tenant recoveries in the consolidated statements of operations, are recognized on a straight line basis over the new remaining lease term when the related lease is canceled. We recognized lease termination revenue of $1.2 million, $1.0 million and $0.5 million during 2021, 2020 and 2019, respectively. Tenant Improvements Tenant improvements constructed, and owned by us, and reimbursed by tenants are recorded as our assets, and the related revenue, which are included in Rental revenues and tenant recoveries in the consolidated statements of operations, is recognized over the related lease term. We recognized revenue for reimbursement of tenant improvements of $5.8 million, $5.9 million and $5.8 million during 2021, 2020 and 2019, respectively. Tenant Recoveries Estimated tenant recoveries for real estate taxes, common area maintenance and other recoverable operating expenses, which are included in Rental revenues and tenant recoveries in the consolidated statements of operations, are recognized as revenue on a gross basis in the period that the recoverable expenses are incurred. Subsequent to year-end, in accordance with our policy, we perform reconciliations on a lease-by-lease basis and bill or credit each tenant for any differences between the estimated expenses we billed to the tenant and the actual expenses incurred. Collectibility In accordance with Topic 842, we perform an assessment as to whether or not substantially all of the amounts due under a tenant’s lease agreement is deemed probable of collection. This assessment involves using a methodology that requires judgment and estimates about matters that are uncertain at the time the estimates are made, including tenant specific factors, specific industry conditions, and general economic trends and conditions. For leases where we have concluded it is probable that we will collect substantially all the lease payments due under those leases, we continue to record lease income on a straight-line basis over the lease term. For leases where we have concluded that it is not probable that we will collect substantially all the lease payments due under those leases, we limit the lease income to the lesser of the income recognized on a straight-line basis or cash basis. If our conclusion of collectibility changes, we will record the difference between the lease income that would have been recognized on a straight-line basis and cash basis as a current-period adjustment to rental revenues and tenant recoveries. We write-off tenant receivables and deferred rent receivables as a charge against rental revenues and tenant recoveries in the period we conclude that substantially all of the lease payments are not probable of collection. If we subsequently collect amounts that were previously written off then the amounts collected are recorded as an increase to our rental revenues and tenant recoveries in the period they are collected. Charges for uncollectible tenant receivables and deferred rent receivables, which were primarily due to the impact of the COVID-19 pandemic, reduced our office revenues by $3.0 million and $41.0 million in 2021 and 2020, respectively. Lease Modifications In April 2020, the FASB staff issued a question and answer document (the “Lease Modification Q&A”) on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. Under the existing lease accounting guidance, we would be required to determine on a lease-by-lease basis if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows us, if certain criteria are met, to bypass the lease-by-lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. We have availed ourselves of the election to avoid performing a lease-by-lease analysis and we have elected to apply the lease modification accounting framework for the lease concessions that meet the criteria.
Office Parking Revenues	Office Parking RevenuesOffice parking revenues, which are included in office Parking and other income in our consolidated statements of operations, are within the scope of Topic 606 "Revenue from Contracts with Customers". Our lease contracts generally make a specified number of parking spaces available to the tenant, and we bill and recognize parking revenues on a monthly basis in accordance with the lease agreements, generally using the monthly parking rates in effect at the time of billing.
Insurance Recoveries	Insurance Recoveries The amount by which insurance recoveries related to property damage exceeds any losses recognized from that damage are recorded as other income when payment has been received or confirmation of the amount of proceeds has been received. In January 2020, there was a fire in one of our residential property buildings. We carry comprehensive liability and property insurance covering all of the properties in our portfolio under blanket insurance policies to cover these kinds of losses. We recorded $4.8 million and $3.9 million of business interruption revenues during 2021 and 2020, respectively, which is included in Multifamily rental - Parking and other income in the consolidated statements of operations. In addition, we recorded a gain related to property damage of $13.1 million during 2020, which is included in Other income in the consolidated statements of operations.
Interest Income	Interest IncomeInterest income from our short-term money market fund investments is recognized on an accrual basis. Interest income is included in other income in the consolidated statements of operations.
Leasing Costs	Leasing CostsWe account for our leasing costs in accordance with Topic 842 "Leases", which we adopted on January 1, 2019 on a modified retrospective basis. In accordance with Topic 842, we capitalize initial direct costs of a lease, which are costs that would not have been incurred had the lease not been executed. Costs to negotiate a lease that would have been incurred regardless of whether the lease was executed, such as employee salaries, are not considered to be initial direct costs, and are expensed as incurred.
Loan Costs	Loan Costs Loan costs incurred directly with the issuance of secured notes payable and revolving credit facilities are deferred and amortized to interest expense over the respective loan or credit facility term. Any unamortized amounts are written off upon early repayment of the secured notes payable, and the related cost and accumulated amortization are removed from our consolidated balance sheets. To the extent that a refinancing is considered an exchange of debt with the same lender, we account for loan costs based upon whether the old debt is determined to be modified or extinguished for accounting purposes. If the old debt is determined to be modified then we (i) continue to defer and amortize any unamortized deferred loan costs associated with the old debt at the time of the modification over the new term of the modified debt, (ii) defer and amortize the lender costs incurred in connection with the modification over the new term of the modified debt, and (iii) expense all other costs associated with the modification. If the old debt is determined to be extinguished then we (i) write off any unamortized deferred loan costs associated with the extinguished debt at the time of the extinguishment and remove the related cost and accumulated amortization from our balance sheet, (ii) expense all lender costs associated with the extinguishment, and (iii) defer and amortize all other costs incurred directly in connection with the extinguishment over the term of the new debt. In circumstances where we modify or exchange our revolving credit facility with the same lender, we account for the loan costs based upon whether the borrowing capacity of the new arrangement is (a) equal to or greater than the borrowing capacity of the old arrangement, or (b) less than the borrowing capacity of the old arrangement (borrowing capacity is defined as the product of the remaining term and the maximum available credit). If the borrowing capacity of the new arrangement is greater than or equal to the borrowing capacity of the old arrangement, then we (i) continue to defer and amortize the unamortized deferred loan costs from the old arrangement over the term of the new arrangement and (ii) defer all lender and other costs incurred directly in connection with the new arrangement over the term of the new arrangement. If the borrowing capacity of the new arrangement is less than the borrowing capacity of the old arrangement, then we (i) write off any unamortized deferred loan costs at the time of the transaction related to the old arrangement in proportion to the decrease in the borrowing capacity of the old arrangement and (ii) defer all lender and other costs incurred directly in connection with the new arrangement over the term of the new arrangement.
Debt Discounts and Premiums	Debt Discounts and Premiums Debt discounts and premiums related to recording debt assumed in connection with property acquisitions at fair value are generally amortized and accreted, respectively, over the remaining term of the related loan, which approximates the effective interest method. The amortization/accretion is included in interest expense in our consolidated statements of operations.
Derivative Contracts	Derivative Contracts We make use of interest rate swap contracts to manage the risk associated with changes in interest rates on our floating-rate debt. When we enter into a floating-rate term loan, we generally enter into an interest rate swap agreement for the equivalent principal amount, for a period covering the majority of the loan term, which effectively converts our floating-rate debt to a fixed-rate basis during that time. We do not speculate in derivatives and we do not make use of any other derivative instruments. When entering into derivative agreements, we generally elect to designate them as cash flow hedges for accounting purposes. Changes in fair value of hedging instruments designated as cash flow hedges are recorded in accumulated other comprehensive income (loss) (AOCI), which is a component of equity outside of earnings. For our Funds' hedging instruments designated as cash flow hedges, we record our share of the changes in fair value of the hedging instrument in AOCI. Amounts recorded in AOCI related to our designated hedges are reclassified to Interest expense as interest payments are made on the hedged floating rate debt. Amounts reported in AOCI related to our Funds' hedges are reclassified to Income from unconsolidated Funds, as interest payments are made by our Funds on their hedged floating rate debt.
Stock-Based Compensation	Stock-Based CompensationWe account for stock-based compensation, which includes grants of LTIP Units, using the fair value method of accounting. The estimated fair value of LTIP Units granted, net of estimated forfeitures, is amortized over the vesting period, which is based upon service.
EPS	EPSWe calculate basic EPS by dividing the net income attributable to common stockholders for the period by the weighted average number of common shares outstanding during the respective period. We calculate diluted EPS by dividing the net income attributable to common stockholders for the period by the weighted average number of common shares and dilutive instruments outstanding during the respective period using the treasury stock method. Unvested LTIP Units contain non-forfeitable rights to dividends and we account for them as participating securities and include them in the computation of basic and diluted EPS using the two-class method.
Segment Information	Segment InformationSegment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate two business segments: the acquisition, development, ownership and management of office real estate, and the acquisition, development, ownership and management of multifamily real estate. The services for our office segment include primarily rental of office space and other tenant services, including parking and storage space rental. The services for our multifamily segment include primarily rental of apartments and other tenant services, including parking and storage space rental.
Income Taxes	Income Taxes We have elected to be taxed as a REIT under the Code, commencing with our initial taxable year ended December 31, 2006. To qualify as a REIT, we are required (among other things) to distribute at least 90% of our REIT taxable income to our stockholders and meet various other requirements imposed by the Code relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided that we qualify for taxation as a REIT, we are generally not subject to corporate-level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. If we fail to qualify as a REIT in any taxable year, and are unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at the regular corporate rate, including any applicable alternative minimum tax for taxable years prior to 2018. We have elected to treat one of our subsidiaries as a TRS, which generally may engage in any business, including the provision of customary or non-customary services to our tenants. A TRS is treated as a regular corporation and is subject to federal income tax and applicable state income and franchise taxes at regular corporate rates. We had two TRSs in 2020 and 2019. Our TRSs did not have significant tax provisions or deferred income tax items for 2021, 2020 or 2019. Our subsidiaries (other than our TRS), including our Operating Partnership, are partnerships, disregarded entities, QRSs or REITs, as applicable, for federal income tax purposes. Under applicable federal and state income tax rules, the allocated share of net income or loss from disregarded entities or flow-through entities is reportable in the income tax returns of the respective owners. Accordingly, no income tax provision is included in our consolidated financial statements for these entities.
New Accounting Pronouncements	New Accounting Pronouncements Changes to US GAAP are implemented by the FASB in the form of ASUs. We consider the applicability and impact of all ASUs. We did not adopt any ASUs during 2021, and as of the date of this Report, the FASB has not issued any ASUs that we expect to be applicable and have a material impact on our future consolidated financial statements.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Our estimates of the fair value of financial instruments were determined using available market information and widely used valuation methods. Considerable judgment is necessary to interpret market data and determine an estimated fair value. The use of different market assumptions or valuation methods may have a material effect on the estimated fair values. The FASB fair value framework hierarchy distinguishes between assumptions based on market data obtained from sources independent of the reporting entity, and the reporting entity’s own assumptions about market-based inputs. The hierarchy is as follows: Level 1 - inputs utilize unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 - inputs are observable either directly or indirectly for similar assets and liabilities in active markets.
