Basis Of Presentation And Significant Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	2. Basis of Presentation and Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and with the rules and regulations of the Securities and Exchange Commission (the “SEC”). These consolidated financial statements include the accounts of Paramount and its consolidated subsidiaries, including the Operating Partnership. All significant intercompany balances and transactions have been eliminated in consolidation. Significant Accounting Policies Real Estate Real estate is carried at cost less accumulated depreciation and amortization. Betterments, major renovations and certain costs directly related to the improvement of real estate are capitalized. Maintenance and repair expenses are charged to expense as incurred. Depreciation is recognized on a straight-line basis over estimated useful lives of the assets, which range from 5 to 40 years. Tenant improvements are amortized on a straight-line basis over the lives of the related leases, which approximate the useful lives of the assets. Upon the acquisition of real estate, we assess the fair value of acquired assets (including land, buildings and improvements, identified intangibles, such as acquired above-market leases and acquired in-place leases) and acquired liabilities (such as acquired below-market leases) and allocate the purchase price based on these assessments. We assess fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including historical operating results, known trends, and market/economic conditions. We record acquired intangible assets (including acquired above-market leases and acquired in-place leases) and acquired intangible liabilities (including below-market leases) at their estimated fair value. We amortize acquired above-market and below-market leases as a decrease or increase to rental revenue, respectively, over the lives of the respective leases. Amortization of acquired in-place leases is included as a component of “depreciation and amortization”. Our properties, including any related intangible assets, are individually reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment analyses are based on our current plans, intended holding periods and available market information at the time the analyses are prepared. An impairment exists when the carrying amount of an asset exceeds the aggregate projected future cash flows over the anticipated holding period on an undiscounted basis. An impairment loss is measured based on the excess of the property’s carrying amount over its estimated fair value. Estimates of fair value are determined using discounted cash flow models, which consider, among other things, anticipated holding periods, current market conditions and utilize unobservable quantitative inputs, including appropriate capitalization and discount rates. If our estimates of the projected future cash flows, anticipated holding periods, or market conditions change, our evaluation of impairment losses may be different and such differences could be material to our consolidated financial statements. The evaluation of anticipated cash flows is subjective and is based, in part, on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results. Plans to hold properties over longer periods decrease the likelihood of recording impairment losses. Real estate and related intangibles are classified as held for sale when all the necessary criteria are met. The criteria include (i) management, having the authority to approve action, commits to a plan to sell the property in its present condition, (ii) the sale of the property is at a price reasonable in relation to its current fair value and (iii) the sale is probable and expected to be completed within one year. Real estate and the related intangibles held for sale are carried at the lower of carrying amounts or estimated fair value less disposal costs. Depreciation and amortization is not recognized on real estate and related intangibles classified as assets held for sale. Variable Interest Entities (“VIEs”) and Investments in Unconsolidated Joint Ventures and Funds We consolidate VIEs in which we are considered to be the primary beneficiary. Entities are considered to be the primary beneficiary if they have both of the following characteristics: (i) the power to direct the activities that, when taken together, most significantly impact the VIE’s performance, and (ii) the obligation to absorb losses and right to receive the returns from the VIE that would be significant to the VIE. Our judgment with respect to our level of influence or control of an entity involves the consideration of various factors including the form of our ownership interest, our representation in the entity’s governance, the size of our investment, estimates of future cash flows, our ability to participate in policy making decisions and the rights of the other investors to participate in the decision making process and to replace us as manager and/or liquidate the joint venture, if applicable. We account for investments under the equity method when the requirements for consolidation are not met, and we have significant influence over the operations of the investee. Equity method investments, which consists of investments in unconsolidated joint ventures and funds are initially recorded at cost and subsequently adjusted for our share of net income or loss and cash contributions and distributions each period. To the extent that our cost basis is different than our share of the equity in the equity method investment, the basis difference allocated to depreciable assets is amortized into “income from unconsolidated joint ventures” over the estimated useful life of the related asset. Investments that do not qualify for consolidation or equity method accounting are accounted for under the cost method. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and short-term highly liquid investments with original maturities of three months or less. The majority of our cash and cash equivalents are held at major commercial banks, which may at times exceed the Federal Deposit Insurance Corporation limit. To date, we have not experienced any losses on our invested cash. Restricted Cash Restricted cash consists primarily of security deposits held on behalf of our tenants, cash escrowed under loan agreements for debt service, real estate taxes, property insurance and capital improvements and cash restricted in connection with our deferred compensation plan. Preferred Equity Investments Preferred equity investments are comprised of investments in certain partnerships that own real estate. We evaluate the collectability of preferred equity investments when changes in events or circumstances, including delinquencies, loss experience and collateral quality, indicate that it is probable we will be unable to collect all amounts due under the contractual terms. If a preferred equity investment is considered impaired, a valuation allowance is measured and recorded based on the excess of the carrying amount of the investment over the net realizable value of the collateral. Marketable Securities Marketable securities consists of investments in trading securities that are held in our deferred compensation plan for which there is an offsetting liability. These investments are initially recorded at cost and subsequently measured at fair value at the end of each reporting period, with gains or losses resulting from changes in fair value recognized in earnings, which are included as a component of “interest and other income (loss), net” on our consolidated statements of income and the earnings are entirely offset by expenses from the mark-to-market of plan liabilities, which are included as a component of “general and administrative” expenses on our consolidated statements of income. Deferred Charges Deferred charges include deferred leasing costs and deferred financing costs related to our revolving credit facility. Deferred leasing costs consist of fees and direct costs related to successful leasing activities. Such costs are amortized on a straight-line basis over the lives of the related leases and recognized in our consolidated statements of income as a component of “depreciation and amortization”. Deferred financing costs consist of fees and direct costs incurred in obtaining our revolving credit facility. Such costs are amortized over the term of the revolving credit facility and are recognized as a component of “interest and debt expense” on our consolidated statements of income. Deferred Financing Costs Related to Notes and Mortgages Payable Deferred financing costs related to notes and mortgages payable consists of fees and direct costs incurred in obtaining such financing and are recorded as a reduction of our notes and mortgages payable. Such costs are amortized over the terms of the related debt agreements and recognized as a component of “interest and debt expense” on our consolidated statements of income. Upon the early extinguishment of our notes and mortgages payable, any unamortized costs related to such notes and mortgages payable are written off as a component of “loss on early extinguishment of debt” on our consolidated statements of income. Derivative Instruments and Hedging Activities We record all derivatives on our consolidated balance sheets at fair value in accordance with Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging Fair Value of Financial Instruments ASC Topic 820, Fair Value Measurement and Disclosures We use the following methods and assumptions in estimating fair value for financial instruments that are presented at fair value on our consolidated balance sheets: Interest Rate Swaps Interest rate swaps are valued by a third-party specialist using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each swap. This analysis reflects the contractual terms of the interest rate swaps and uses observable market-based inputs, including interest rate curves and implied volatilities. Interest rate swaps are classified as Level 2 in the fair value hierarchy. We use the following methods and assumptions in estimating fair value for financial instruments that are not presented at fair value on our consolidated balance sheets, but are disclosed in the notes to our consolidated financial statements: Preferred Equity Investments Preferred equity investments are valued by a third-party specialist using the standard practice of modeling the contractual cash flows required under the instrument and discounting them back to their present value. We use significant unobservable inputs in determining the discount rate used in the fair value measurement of these investments, including a credit spread and preferred rate of return. Preferred equity investments are classified as Level 3 in the fair value hierarchy. Notes and Mortgages Payable Notes and mortgages payable are valued by a third-party specialist using the standard practice of modeling the contractual cash flows required under the instrument and discounting them back to their present value at the appropriate current risk adjusted interest rate. For floating rate debt, we use forward rates derived from observable market yield curves to project the expected cash payments we would be required to make under the instrument. The notes and mortgages payable are classified as Level 2 in fair value hierarchy. The carrying value of marketable securities is determined using quoted prices in active markets. The carrying values of all other financial instruments on our consolidated balance sheets, including cash and cash equivalents, restricted cash, accounts and other receivables and accounts payable and accrued expenses, approximate their fair values due to the short-term nature of these instruments. Revenue Recognition Our revenues consist of rental revenues and revenues from contracts with customers. Rental Revenue Rental revenue is recognized in accordance with ASC Topic 842, Leases We evaluate the collectibility of our tenant receivables for payments required under the lease agreements. If we determine that collectibility is not probable, the difference between rental revenue recognized and rental payments received is recorded as an adjustment to “rental revenue” in our consolidated statements of income. Revenue from Contracts with Customers Revenue from contracts with customers, which is primarily comprised of (i) property management fees, (ii) asset management fees, (iii) fees relating to acquisitions, dispositions and leasing services and (iv) other fee income, is recognized in accordance with ASC Topic 606, Revenue from Contracts with Customers Fee income is recognized as and when we satisfy our performance obligations pursuant to contractual agreements. Property management and asset management services are provided continuously over time and revenue is recognized over that time. Fee income relating to acquisitions, dispositions and leasing services is recognized upon completion of the acquisition, disposition or leasing services as required in the contractual agreements. The amount of fee income to be recognized is stated in the contract as a fixed price or as a stated percentage of revenues, contributed capital or transaction price. Gains and Losses on Sale of Real Estate Gains and losses on the sale of real estate are recognized pursuant to ASC Topic 610-20, Gains and Losses from the Derecognition of Nonfinancial Assets, Stock-based Compensation We account for stock-based compensation in accordance with ASC Topic 718, Compensation – Stock Compensation Income Taxes We operate and have been organized in conformity with the requirements for qualification and taxation as a REIT for U.S. federal income tax purposes. So long as we qualify as a REIT, we generally will not be subject to U.S. federal income tax on our net income that we distribute currently to our stockholders. In order to maintain our qualification as a REIT, we are required under the Internal Revenue Code of 1986, as amended, to distribute at least 90% of our taxable income (without regard to the deduction for dividends paid and excluding net capital gains) to our stockholders and meet certain other requirements. If, with respect to any taxable year, we fail to maintain our qualification as a REIT, and we are not entitled to relief under the relevant statutory provisions, we would be subject to income tax at regular corporate tax rates. Even if we qualify as a REIT, we may also be subject to certain state, local and franchise taxes. Under certain circumstances, U.S. federal income tax may be due on our undistributed taxable income. We treat certain consolidated subsidiaries, and may in the future elect to treat newly formed subsidiaries, as taxable REIT subsidiaries (“TRSs”). TRSs may participate in non-real estate related activities and/or perform non-customary services for tenants and are subject to federal and state income tax at regular corporate tax rates. Our TRSs had a combined current income tax expense of approximately $242,000, $622,000 and $5,758,000 for the years ended December 31, 2019, 2018 and 2017, respectively. In addition, our TRSs had combined deferred income tax benefit of $28,000 and $922,000 for the years ended December 31, 2019 and 2017, respectively, and a combined deferred income tax expense of $87,000 for the year ended December 31, 2018.

Segments Our reportable segments are separated by region based on the three regions in which we conduct our business: New York , San Francisco and Washington D.C. Our determination of segments is aligned with our method of internal reporting and the way our Chief Executive Officer, who is also our Chief Operating Decision Maker, makes key operating decisions, evaluates financial results and manages our business. See Note 24, Segments . Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ materially from those estimates. Reclassification Certain prior year balances have been reclassified to conform to current year presentation. Recently Issued Accounting Pronouncements Not Materially Impacting Our Financial Statements In June 2016, the Financial Accounting Standards Board Financial Instruments – Credit Losses Leases In August 2018, the FASB issued ASU 2018-13, an update to ASC Topic 820, Fair Value Measurements In October 2018, the FASB issued ASU 2018-17, an update to ASC Topic 810, Consolidations In December 2018, the FASB issued ASU 2018-20, an update to ASC Topic 842, Leases In December 2019, the FASB issued ASU 2019-12, an update to ASC Topic 740, Income Taxes. Recently Issued Accounting Pronouncements Impacting or Potentially Impacting Our Financial Statements In February 2016, the FASB issued ASU 2016-02, an update to ASC Topic 842, Leases While accounting for lessors under ASU 2016-02 is substantially similar to existing lease accounting guidance, lessors are required to separate payments received pursuant to a lease between lease components (payments received towards the leased space) and non-lease components (payments received towards common area maintenance activities). In July 2018, the FASB issued ASU 2018-11, which provided lessors with a practical expedient to not separate lease and non-lease components, if certain criteria are met. Upon the adoption of ASU 2016-02, we elected this practical expedient and accordingly, have combined lease and non-lease components into rental revenue on our consolidated statements of income. We account for both components under ASC Topic 842. ASU 2016-02 also requires companies to account for the impairment of receivables arising from operating leases (previously recorded as bad debt expense, a component of “operating expenses”), as a reduction to “rental income”. Accordingly, beginning on January 1, 2019, impairment of receivables arising from operating leases have been recorded as a reduction of rental income and are no longer reflected as bad debt expense. Furthermore, ASU 2016-02 also updates the definition of initial direct costs for both lessees and lessors to include only incremental costs of a lease that would not have been incurred if the lease had not been obtained. This ASU also provides a package of practical expedients which permits companies not to reassess under ASC Topic 842, its prior conclusions about lease identification, lease classification and initial direct costs. Upon adoption of ASU 2016-02, we elected this practical expedient and accordingly, effective January 1, 2019, we no longer capitalize internal leasing costs.

Investments in Unconsolidated Joint Ventures	4. Investments in Unconsolidated Joint Ventures 111 Sutter Street On February 7, 2019, we completed the acquisition of 111 Sutter Street, a 293,000 square foot Class A office building in San Francisco, California. Simultaneously with closing, we brought in a joint venture partner to acquire 51.0% of the equity interest. We have retained the remaining 49.0% equity interest and manage and lease the asset. The purchase price was $227,000,000. In connection with the acquisition, the joint venture completed a $138,200,000 financing of the property. The four-year one-year One Steuart Lane Prior to 2019, our consolidated Residential Development Fund (“RDF”), in which we have a 7.4% interest, owned a 25.0% economic interest in One Steuart Lane, a residential condo development project (the “project”) in San Francisco, California. Accordingly, prior to 2019, our economic interest in the project was 1.9%. In March 2019 and again in September 2019, RDF acquired an additional 10.0% economic interest in the project, in two separate transactions, for an aggregate of $19,110,000. Subsequent to these transactions, RDF economic interest in the project increased to 35.0% and our economic interest (based on our 7.4% ownership) increased to 2.6%. We continue to consolidate our 7.4% interest in RDF and reflect the 92.6% interest we do not own as “noncontrolling interests” in our consolidated financial statements. 55 Second Street On August 21, 2019, we acquired a 44.1% equity interest in a joint venture that owns 55 Second Street, a 384,000 square foot Class A office building in San Francisco, California. The transaction valued the property at $401,700,000. In connection with the acquisition, the joint venture assumed the existing $137,500,000 mortgage loan and upsized it by an additional $50,000,000. The $187,500,000 mortgage loan is interest only at a fixed rate of 3.88% and matures in October 2026. We began accounting for our investment in 55 Second Street, under the equity method of accounting, from the date of the acquisition. Market Center On December 11, 2019, we completed the acquisition of Market Center, a two-building Class A office complex comprising 747,000 square feet, in San Francisco, California, through a joint venture in which we own a 67.0% interest. The transaction valued the property at $722,000,000. In connection with the acquisition, the joint venture completed a $402,000,000 financing of the property for an initial term of five years, with two one-year The following tables summarize our investments in unconsolidated joint ventures as of the dates thereof and the income or loss from these investments for the periods set forth below.

Preferred Equity Investments	6 . Preferred Equity Investments We owned a 24.4% interest in PGRESS Equity Holdings LP (“PGRESS”), an entity that owned a preferred equity investment in a partnership that owned 470 Vanderbilt, a 686,000 square foot office building in Brooklyn, New York.

Hamburg Trust Consulting GMBH (“HTC”) We have an agreement with HTC, a licensed broker in Germany, to supervise selling efforts for our private equity real estate funds (or investments in feeder vehicles for these funds) to investors in Germany, including distribution of securitized notes of feeder vehicles for Fund VIII and Fund X. Pursuant to this agreement, we have agreed to pay HTC for the costs incurred to sell investments in these feeder vehicles, which primarily consist of commissions paid to third party agents, and other incremental costs incurred by HTC as a result of the engagement, plus, in each case, a mark-up of 10%. HTC is 100% owned by Albert Behler, our Chairman, Chief Executive Officer and President. We incurred expenses of $796,000, $240,000 and $247,000 for the years ended December 31, 2019, 2018 and 2017, respectively, in connection with this agreement, which is included as a component of “transaction related costs” on our consolidated statements of income.

Dr. Martin Bussmann (a member of our Board of Directors) is also a trustee and a director of Mannheim Trust. During the years ended December 31, 2019, 2018 and 2017, we recognized $360,000, $366,000 and $358,000, respectively, for our share of rental income pursuant to this lease. Due from Affiliates At December 31, 2019, we had a $36,918,000 note receivable from Fund X that bears interest at LIBOR plus 220 basis points and is included as “due from affiliates” on our consolidated balance sheet.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	23. Commitments and Contingencies Insurance We carry commercial general liability coverage on our properties, with limits of liability customary within the industry. Similarly, we are insured against the risk of direct and indirect physical damage to our properties including coverage for the perils such as floods, earthquakes and windstorms. Our policies also cover the loss of rental income during an estimated reconstruction period. Our policies reflect limits and deductibles customary in the industry and specific to the buildings and portfolio. We also obtain title insurance policies when acquiring new properties. We currently have coverage for losses incurred in connection with both domestic and foreign terrorist-related activities. While we do carry commercial general liability insurance, property insurance and terrorism insurance with respect to our properties, these policies include limits and terms we consider commercially reasonable. In addition, there are certain losses (including, but not limited to, losses arising from known environmental conditions or acts of war) that are not insured, in full or in part, because they are either uninsurable or the cost of insurance makes it, in our belief, economically impractical to maintain such coverage. Should an uninsured loss arise against us, we would be required to use our own funds to resolve the issue, including litigation costs. We believe the policy specifications and insured limits are adequate given the relative risk of loss, the cost of the coverage and industry practice and, in consultation with our insurance advisors, we believe the properties in our portfolio are adequately insured. Other Commitments and Contingencies We are a party to various claims and routine litigation arising in the ordinary course of business. Some of these claims or others to which we may be subject from time to time, including claims arising specifically from the Formation Transactions, in connection with our initial public offering, may result in defense costs, settlements, fines or judgments against us, some of which are not, or cannot be, covered by insurance. Payment of any such costs, settlements, fines or judgments that are not insured could have an adverse impact on our financial position and results of operations. Should any litigation arise in connection with the Formation Transactions, we would contest it vigorously. In addition, certain litigation or the resolution of certain litigation may affect the availability or cost of some of our insurance coverage, which could adversely impact our results of operations and cash flow, expose us to increased risks that would be uninsured, and/or adversely impact our ability to attract officers and directors. The terms of our mortgage debt and certain side letters in place include certain restrictions and covenants which may limit, among other things, certain investments, the incurrence of additional indebtedness and liens and the disposition or other transfer of assets and interests in the borrower and other credit parties, and require compliance with certain debt yield, debt service coverage and loan to value ratios. In addition, our revolving credit facility contains representations, warranties, covenants, other agreements and events of default customary for agreements of this type with comparable companies. As of December 31, 201 9 , we believe we are in compliance with all of our covenants. 718 Fifth Avenue - Put Right Prior to the Formation Transactions, an affiliate of our Predecessor owned a 25.0% interest in 718 Fifth Avenue, a five-story building containing 19,050 square feet of prime retail space that is located on the southwest corner of 56th Street and Fifth Avenue in New York, New York (based on its 50.0% interest in a joint venture that held a 50.0% tenancy-in-common interest in the property). Prior to the completion of the Formation Transactions, this interest was sold to its partner in the 718 Fifth Avenue joint venture, who is also our joint venture partner in 712 Fifth Avenue, New York, New York. In connection with this sale, we granted our joint venture partner a put right, pursuant to which the 712 Fifth Avenue joint venture would be required to purchase the entire direct or indirect interests then held by our joint venture partner or its affiliates in 718 Fifth Avenue at a purchase price equal to the fair market value of such interests. The put right may be exercised at any time with the actual purchase occurring no earlier than 12 months after written notice is provided. If the put right is exercised and the 712 Fifth Avenue joint venture acquires the 50.0% tenancy-in-common interest in the property by our joint venture partner, we will own a 25.0% interest in 718 Fifth Avenue based on current ownership interests. Transfer Tax Assessments During 2017, the New York City Department of Finance issued Notices of Determination (“Notices”) assessing additional transfer taxes (including interest and penalties) in connection with the transfer of interests in certain properties during our 2014 initial public offering. We believe, after consultation with legal counsel, that the likelihood of a loss is reasonably possible, and while it is not possible to predict the outcome of these Notices, we estimate the range of loss could be between $0 and $43,500,000. Since no amount in this range is a better estimate than any other amount within the range, we have not accrued any liability arising from potential losses relating to these Notices in our consolidated financial statements.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and with the rules and regulations of the Securities and Exchange Commission (the “SEC”). These consolidated financial statements include the accounts of Paramount and its consolidated subsidiaries, including the Operating Partnership. All significant intercompany balances and transactions have been eliminated in consolidation.
Real Estate	Real Estate Real estate is carried at cost less accumulated depreciation and amortization. Betterments, major renovations and certain costs directly related to the improvement of real estate are capitalized. Maintenance and repair expenses are charged to expense as incurred. Depreciation is recognized on a straight-line basis over estimated useful lives of the assets, which range from 5 to 40 years. Tenant improvements are amortized on a straight-line basis over the lives of the related leases, which approximate the useful lives of the assets. Upon the acquisition of real estate, we assess the fair value of acquired assets (including land, buildings and improvements, identified intangibles, such as acquired above-market leases and acquired in-place leases) and acquired liabilities (such as acquired below-market leases) and allocate the purchase price based on these assessments. We assess fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including historical operating results, known trends, and market/economic conditions. We record acquired intangible assets (including acquired above-market leases and acquired in-place leases) and acquired intangible liabilities (including below-market leases) at their estimated fair value. We amortize acquired above-market and below-market leases as a decrease or increase to rental revenue, respectively, over the lives of the respective leases. Amortization of acquired in-place leases is included as a component of “depreciation and amortization”. Our properties, including any related intangible assets, are individually reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment analyses are based on our current plans, intended holding periods and available market information at the time the analyses are prepared. An impairment exists when the carrying amount of an asset exceeds the aggregate projected future cash flows over the anticipated holding period on an undiscounted basis. An impairment loss is measured based on the excess of the property’s carrying amount over its estimated fair value. Estimates of fair value are determined using discounted cash flow models, which consider, among other things, anticipated holding periods, current market conditions and utilize unobservable quantitative inputs, including appropriate capitalization and discount rates. If our estimates of the projected future cash flows, anticipated holding periods, or market conditions change, our evaluation of impairment losses may be different and such differences could be material to our consolidated financial statements. The evaluation of anticipated cash flows is subjective and is based, in part, on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results. Plans to hold properties over longer periods decrease the likelihood of recording impairment losses. Real estate and related intangibles are classified as held for sale when all the necessary criteria are met. The criteria include (i) management, having the authority to approve action, commits to a plan to sell the property in its present condition, (ii) the sale of the property is at a price reasonable in relation to its current fair value and (iii) the sale is probable and expected to be completed within one year. Real estate and the related intangibles held for sale are carried at the lower of carrying amounts or estimated fair value less disposal costs. Depreciation and amortization is not recognized on real estate and related intangibles classified as assets held for sale.
Variable Interest Entities and Investments in Unconsolidated Joint Ventures and Funds	Variable Interest Entities (“VIEs”) and Investments in Unconsolidated Joint Ventures and Funds We consolidate VIEs in which we are considered to be the primary beneficiary. Entities are considered to be the primary beneficiary if they have both of the following characteristics: (i) the power to direct the activities that, when taken together, most significantly impact the VIE’s performance, and (ii) the obligation to absorb losses and right to receive the returns from the VIE that would be significant to the VIE. Our judgment with respect to our level of influence or control of an entity involves the consideration of various factors including the form of our ownership interest, our representation in the entity’s governance, the size of our investment, estimates of future cash flows, our ability to participate in policy making decisions and the rights of the other investors to participate in the decision making process and to replace us as manager and/or liquidate the joint venture, if applicable. We account for investments under the equity method when the requirements for consolidation are not met, and we have significant influence over the operations of the investee. Equity method investments, which consists of investments in unconsolidated joint ventures and funds are initially recorded at cost and subsequently adjusted for our share of net income or loss and cash contributions and distributions each period. To the extent that our cost basis is different than our share of the equity in the equity method investment, the basis difference allocated to depreciable assets is amortized into “income from unconsolidated joint ventures” over the estimated useful life of the related asset. Investments that do not qualify for consolidation or equity method accounting are accounted for under the cost method.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and short-term highly liquid investments with original maturities of three months or less. The majority of our cash and cash equivalents are held at major commercial banks, which may at times exceed the Federal Deposit Insurance Corporation limit. To date, we have not experienced any losses on our invested cash.
Restricted Cash	Restricted Cash Restricted cash consists primarily of security deposits held on behalf of our tenants, cash escrowed under loan agreements for debt service, real estate taxes, property insurance and capital improvements and cash restricted in connection with our deferred compensation plan.
Preferred Equity Investments	Preferred Equity Investments Preferred equity investments are comprised of investments in certain partnerships that own real estate. We evaluate the collectability of preferred equity investments when changes in events or circumstances, including delinquencies, loss experience and collateral quality, indicate that it is probable we will be unable to collect all amounts due under the contractual terms. If a preferred equity investment is considered impaired, a valuation allowance is measured and recorded based on the excess of the carrying amount of the investment over the net realizable value of the collateral.
Marketable Securities	Marketable Securities Marketable securities consists of investments in trading securities that are held in our deferred compensation plan for which there is an offsetting liability. These investments are initially recorded at cost and subsequently measured at fair value at the end of each reporting period, with gains or losses resulting from changes in fair value recognized in earnings, which are included as a component of “interest and other income (loss), net” on our consolidated statements of income and the earnings are entirely offset by expenses from the mark-to-market of plan liabilities, which are included as a component of “general and administrative” expenses on our consolidated statements of income.
Deferred Charges	Deferred Charges Deferred charges include deferred leasing costs and deferred financing costs related to our revolving credit facility. Deferred leasing costs consist of fees and direct costs related to successful leasing activities. Such costs are amortized on a straight-line basis over the lives of the related leases and recognized in our consolidated statements of income as a component of “depreciation and amortization”. Deferred financing costs consist of fees and direct costs incurred in obtaining our revolving credit facility. Such costs are amortized over the term of the revolving credit facility and are recognized as a component of “interest and debt expense” on our consolidated statements of income.
Deferred Financing Costs Related to Notes and Mortgages Payable	Deferred Financing Costs Related to Notes and Mortgages Payable Deferred financing costs related to notes and mortgages payable consists of fees and direct costs incurred in obtaining such financing and are recorded as a reduction of our notes and mortgages payable. Such costs are amortized over the terms of the related debt agreements and recognized as a component of “interest and debt expense” on our consolidated statements of income. Upon the early extinguishment of our notes and mortgages payable, any unamortized costs related to such notes and mortgages payable are written off as a component of “loss on early extinguishment of debt” on our consolidated statements of income.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities We record all derivatives on our consolidated balance sheets at fair value in accordance with Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging
Fair Value of Financial Instruments	Fair Value of Financial Instruments ASC Topic 820, Fair Value Measurement and Disclosures We use the following methods and assumptions in estimating fair value for financial instruments that are presented at fair value on our consolidated balance sheets: Interest Rate Swaps Interest rate swaps are valued by a third-party specialist using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each swap. This analysis reflects the contractual terms of the interest rate swaps and uses observable market-based inputs, including interest rate curves and implied volatilities. Interest rate swaps are classified as Level 2 in the fair value hierarchy. We use the following methods and assumptions in estimating fair value for financial instruments that are not presented at fair value on our consolidated balance sheets, but are disclosed in the notes to our consolidated financial statements: Preferred Equity Investments Preferred equity investments are valued by a third-party specialist using the standard practice of modeling the contractual cash flows required under the instrument and discounting them back to their present value. We use significant unobservable inputs in determining the discount rate used in the fair value measurement of these investments, including a credit spread and preferred rate of return. Preferred equity investments are classified as Level 3 in the fair value hierarchy. Notes and Mortgages Payable Notes and mortgages payable are valued by a third-party specialist using the standard practice of modeling the contractual cash flows required under the instrument and discounting them back to their present value at the appropriate current risk adjusted interest rate. For floating rate debt, we use forward rates derived from observable market yield curves to project the expected cash payments we would be required to make under the instrument. The notes and mortgages payable are classified as Level 2 in fair value hierarchy. The carrying value of marketable securities is determined using quoted prices in active markets. The carrying values of all other financial instruments on our consolidated balance sheets, including cash and cash equivalents, restricted cash, accounts and other receivables and accounts payable and accrued expenses, approximate their fair values due to the short-term nature of these instruments.
Revenue Recognition	Revenue Recognition Our revenues consist of rental revenues and revenues from contracts with customers. Rental Revenue Rental revenue is recognized in accordance with ASC Topic 842, Leases We evaluate the collectibility of our tenant receivables for payments required under the lease agreements. If we determine that collectibility is not probable, the difference between rental revenue recognized and rental payments received is recorded as an adjustment to “rental revenue” in our consolidated statements of income. Revenue from Contracts with Customers Revenue from contracts with customers, which is primarily comprised of (i) property management fees, (ii) asset management fees, (iii) fees relating to acquisitions, dispositions and leasing services and (iv) other fee income, is recognized in accordance with ASC Topic 606, Revenue from Contracts with Customers Fee income is recognized as and when we satisfy our performance obligations pursuant to contractual agreements. Property management and asset management services are provided continuously over time and revenue is recognized over that time. Fee income relating to acquisitions, dispositions and leasing services is recognized upon completion of the acquisition, disposition or leasing services as required in the contractual agreements. The amount of fee income to be recognized is stated in the contract as a fixed price or as a stated percentage of revenues, contributed capital or transaction price.
Gains and Losses on Sale of Real Estate	Gains and Losses on Sale of Real Estate Gains and losses on the sale of real estate are recognized pursuant to ASC Topic 610-20, Gains and Losses from the Derecognition of Nonfinancial Assets,
Stock-based Compensation	Stock-based Compensation We account for stock-based compensation in accordance with ASC Topic 718, Compensation – Stock Compensation
Income Taxes	Income Taxes We operate and have been organized in conformity with the requirements for qualification and taxation as a REIT for U.S. federal income tax purposes. So long as we qualify as a REIT, we generally will not be subject to U.S. federal income tax on our net income that we distribute currently to our stockholders. In order to maintain our qualification as a REIT, we are required under the Internal Revenue Code of 1986, as amended, to distribute at least 90% of our taxable income (without regard to the deduction for dividends paid and excluding net capital gains) to our stockholders and meet certain other requirements. If, with respect to any taxable year, we fail to maintain our qualification as a REIT, and we are not entitled to relief under the relevant statutory provisions, we would be subject to income tax at regular corporate tax rates. Even if we qualify as a REIT, we may also be subject to certain state, local and franchise taxes. Under certain circumstances, U.S. federal income tax may be due on our undistributed taxable income. We treat certain consolidated subsidiaries, and may in the future elect to treat newly formed subsidiaries, as taxable REIT subsidiaries (“TRSs”). TRSs may participate in non-real estate related activities and/or perform non-customary services for tenants and are subject to federal and state income tax at regular corporate tax rates. Our TRSs had a combined current income tax expense of approximately $242,000, $622,000 and $5,758,000 for the years ended December 31, 2019, 2018 and 2017, respectively. In addition, our TRSs had combined deferred income tax benefit of $28,000 and $922,000 for the years ended December 31, 2019 and 2017, respectively, and a combined deferred income tax expense of $87,000 for the year ended December 31, 2018.

Segments	Segments Our reportable segments are separated by region based on the three regions in which we conduct our business: New York , San Francisco and Washington D.C. Our determination of segments is aligned with our method of internal reporting and the way our Chief Executive Officer, who is also our Chief Operating Decision Maker, makes key operating decisions, evaluates financial results and manages our business. See Note 24, Segments .
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ materially from those estimates.
Reclassification	Reclassification Certain prior year balances have been reclassified to conform to current year presentation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Not Materially Impacting Our Financial Statements In June 2016, the Financial Accounting Standards Board Financial Instruments – Credit Losses Leases In August 2018, the FASB issued ASU 2018-13, an update to ASC Topic 820, Fair Value Measurements In October 2018, the FASB issued ASU 2018-17, an update to ASC Topic 810, Consolidations In December 2018, the FASB issued ASU 2018-20, an update to ASC Topic 842, Leases In December 2019, the FASB issued ASU 2019-12, an update to ASC Topic 740, Income Taxes. Recently Issued Accounting Pronouncements Impacting or Potentially Impacting Our Financial Statements In February 2016, the FASB issued ASU 2016-02, an update to ASC Topic 842, Leases While accounting for lessors under ASU 2016-02 is substantially similar to existing lease accounting guidance, lessors are required to separate payments received pursuant to a lease between lease components (payments received towards the leased space) and non-lease components (payments received towards common area maintenance activities). In July 2018, the FASB issued ASU 2018-11, which provided lessors with a practical expedient to not separate lease and non-lease components, if certain criteria are met. Upon the adoption of ASU 2016-02, we elected this practical expedient and accordingly, have combined lease and non-lease components into rental revenue on our consolidated statements of income. We account for both components under ASC Topic 842. ASU 2016-02 also requires companies to account for the impairment of receivables arising from operating leases (previously recorded as bad debt expense, a component of “operating expenses”), as a reduction to “rental income”. Accordingly, beginning on January 1, 2019, impairment of receivables arising from operating leases have been recorded as a reduction of rental income and are no longer reflected as bad debt expense. Furthermore, ASU 2016-02 also updates the definition of initial direct costs for both lessees and lessors to include only incremental costs of a lease that would not have been incurred if the lease had not been obtained. This ASU also provides a package of practical expedients which permits companies not to reassess under ASC Topic 842, its prior conclusions about lease identification, lease classification and initial direct costs. Upon adoption of ASU 2016-02, we elected this practical expedient and accordingly, effective January 1, 2019, we no longer capitalize internal leasing costs.
