Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements of the Company and the operating partnership are prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) applicable to interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to the Securities and Exchange Commission (“SEC”) rules and regulations. Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying interim financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. References to number of properties, square feet and credit rating are not covered by the auditor’s review procedures. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ended December 31, 2019. The interim consolidated financial statements should be read in conjunction with the consolidated financial statements in the 2018 Annual Report on Form 10-K of Hudson Pacific Properties, Inc. and Hudson Pacific Properties, L.P. and the notes thereto. Principles of Consolidation The unaudited interim consolidated financial statements of the Company include the accounts of the Company, the operating partnership and all wholly owned and controlled subsidiaries. The consolidated financial statements of the operating partnership include the accounts of the operating partnership and all wholly owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements. Under the consolidation guidance, the Company first evaluates an entity using the variable interest model, then the voting model. The Company ultimately consolidates all entities that the Company controls through either majority ownership or voting rights, including all variable interest entities (“VIEs”) of which the Company is considered the primary beneficiary. The Company accounts for all other unconsolidated joint ventures using the equity method of accounting. In addition, the Company continually evaluates each legal entity that is not wholly owned for reconsideration based on changing circumstances. VIEs are defined as entities in which equity investors do not have: • the characteristics of a controlling financial interest; • sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties; and/or • the entity is structured with non-substantive voting rights. The entity that consolidates a VIE is known as its primary beneficiary and is generally the entity with both the power to direct the activities that most significantly affect the VIE’s economic performance and the right to receive benefits from the VIE or the obligation to absorb losses of the VIE that could be significant to the VIE. As of September 30, 2019, the Company has determined its operating partnership and five joint ventures met the definition of a VIE. Four of the joint ventures are consolidated and one of the joint ventures is unconsolidated. Consolidated Joint Ventures As of September 30, 2019, the operating partnership has determined that four of its joint ventures met the definition of a VIE and are consolidated: Entity Property Ownership Interest Hudson 1455 Market, L.P. 1455 Market 55.0 % Hudson 1099 Stewart, L.P. Hill7 55.0 % HPP-MAC WSP, LLC One Westside and 10850 Pico 75.0 % Hudson One Ferry REIT, L.P. Ferry Building 55.0 % As of September 30, 2019 and December 31, 2018, the Company has determined that its operating partnership met the definition of a VIE and is consolidated. Substantially all of the assets and liabilities of the Company are related to the operating partnership VIE. Unconsolidated Joint Ventures As of September 30, 2019, the Company has determined it is not the primary beneficiary of one joint venture. Due to its significant influence over the unconsolidated entity, the Company accounts for the entity using the equity method of accounting. Under the equity method, the Company initially records the investment at cost and subsequently adjusts for equity in earnings or losses and cash contributions and distributions. On June 5, 2019, the Company purchased, pursuant to a co-ownership agreement with Blackstone, the Bentall Centre property located in Vancouver, Canada. The joint venture property-owning entity is structured as a tenancy in common under applicable tax laws. The Company owns 20% of this joint venture and serves as the operating partner. The Company’s net equity investment of this unconsolidated entity is reflected within investment in unconsolidated real estate entity on the Consolidated Balance Sheets. The Company’s share of net income or loss from the entity is included within loss from unconsolidated real estate investments on the Consolidated Statements of Operations. Refer to note 4 for details. On June 16, 2016, the Company entered into a joint venture to co-originate a loan secured by land in Santa Clara, California. The Company owned 21% of the unconsolidated non-real estate entity. In the third quarter of 2019, the joint venture was dissolved. The Company’s net equity investment in the unconsolidated joint venture was $0.0 and $86 thousand as of September 30, 2019 and December 31, 2018, respectively, which is reflected within prepaid expenses and other assets, net line item on the Consolidated Balance Sheets. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of commitments and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to acquiring, developing and assessing the carrying values of its real estate properties, determining the incremental borrowing rate used in the present value calculations of its new or modified operating lessee agreements, its accrued liabilities and its performance-based equity compensation awards. The Company bases its estimates on historical experience, current market conditions and various other assumptions that are believed to be reasonable under the circumstances. Actual results could materially differ from these estimates. Lease Accounting In February 2016, the FASB issued guidance codified in ASC 842, Leases (“ASC 842”), which amends the guidance in former ASC 840, Leases (“ASC 840”). The standard sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a lease agreement (i.e., lessees and lessors). The new standard increases transparency and comparability most significantly by requiring the recognition by lessees of right-of-use (“ROU”) assets and lease liabilities on the balance sheet for those leases classified as operating leases. The Company adopted ASC 842 on January 1, 2019 using the modified retrospective transition approach that must be applied for leases that exist or are entered into after January 1, 2019. ASC 842 requires companies to identify lease and non-lease components of a lease agreement. Lease components relate to the right to use the leased asset whereas non-lease components relate to payments for goods or services that are transferred separately from the right to use the underlying asset. ASC 842 provides transition practical expedients that must be elected together, which allows relief from the requirement to (i) reassess whether any expired or existing contracts are considered or contain leases; (ii) reassess the lease classification for any expired or existing leases; and (iii) reassess initial direct costs for any existing leases that are in effect as of the date of adoption. The guidance also permits an entity to elect a practical expedient that provides relief from the requirement to assess whether an existing or expired land easement that was not previously accounted for as a lease under ASC 840 is considered a lease under ASC 842. For lessors, the guidance provides for a practical expedient, by class of underlying asset, to elect a combined single lease component presentation if (i) the timing and pattern of the transfer of the combined single lease component is the same, and (ii) the related lease component, if accounted for separately, would be classified as an operating lease. The Company elected the practical expedients above. The lessor practical expedient to combine lease and non-lease components was elected only for the Company’s leases related to the office properties. For the Company’s studio properties, the timing and pattern of the transfer of the lease components and non-lease components for studio properties are not the same and therefore the Company could not elect this practical expedient for the Company’s studio properties. The standalone selling price related to the studio non-lease components is readily available and does not require estimates. Lessee Accounting The Company determines if an arrangement is a lease at inception. The Company’s operating lease agreements relate to ground lease assets and are reflected in operating lease ROU assets and operating lease liabilities on the Consolidated Balance Sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Variable lease payments are excluded from the ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. As the Company’s leases do not provide an implicit rate, the Company determines its incremental borrowing rate based on the information available at commencement date, or the date of the ASC 842 adoption, in determining the present value of lease payments. The weighted average incremental borrowing rate used to calculate the ROU assets and liabilities as of September 30, 2019 was 5.7%. ROU assets also include any lease payments made and exclude lease incentives. Many of the Company’s lessee agreements include options to extend the lease, which we do not include in its minimum lease terms unless the option is reasonably certain to be exercised. Rental expense for lease payments related to operating leases is recognized on a straight-line basis over the lease term. The weighted average remaining lease term, as of September 30, 2019, was 32 years. Lessor Accounting As a lessor, the Company’s recognition of revenue remained consistent with previous guidance, apart from the narrower definition of initial direct costs that can be capitalized. With the election of the lessor practical expedient, the presentation of revenues on the Consolidated Statement of Operations has changed to reflect a single lease component that combines rental, tenant recoveries, and other tenant-related revenues for the office portfolio. For the Company’s rentals at the studio properties, total lease consideration is allocated to lease and non-lease components on a relative standalone basis. The recognition of revenues related to lease components is governed by ASC 842, while revenue related to non-lease components is subject to ASC 606, Revenue from Contracts with Customers (“ASC 606”). The new standard defines initial direct costs as only the incremental costs of signing a lease. Internal direct compensation costs and external legal fees related to the execution of successful lease agreements that no longer meet the definition of initial direct costs under ASC 842 are accounted for as office operating expense or studio operating expense in the Company’s Consolidated Statements of Operations. Additionally, the Company may elect the practical expedients only for leases that have commenced before the effective date of the adoption of ASC 842. As a result of the adoption, the Company recognized $1.8 million as a cumulative adjustment to accumulated deficit for costs associated with leases that have not commenced as of January 1, 2019, that were previously capitalized and no longer meet the definition of initial direct costs in accordance with ASC 842. The Company recognized $0.3 million as cumulative adjustments to accumulated deficit related to other transition adjustments. Revenue Recognition The Company has compiled an inventory of its sources of revenues and has identified the following material revenue streams: (i) rental revenues (ii) tenant recoveries and other tenant-related revenues (iii) ancillary revenues (iv) other revenues and (v) sale of real estate. Revenue Stream Components Financial Statement Location (1) Rental revenues Office rentals, stage rentals and storage rentals Office and studio segments: rental Tenant recoveries and other tenant-related revenues Reimbursement of real estate taxes, insurance, repairs and maintenance, other operating expenses and must-take parking revenues Office segment: rental Ancillary revenues Revenues derived from tenants’ use of lighting, equipment rental, power, HVAC and telecommunications (i.e., telephone and internet) Studio segment: service revenues and other Other revenues Parking revenue that is not associated with lease agreements, management fees, and other Office and studio segments: service revenues and other Sale of real estate Gains on sales derived from cash consideration less cost basis Gains on sale of real estate _________________ 1. The financial statement locations stated above are for the nine months ended September 30, 2019, after the adoption of ASC 842, and do not reflect the locations for the nine months ended September 30, 2018. The Company’s 2018 rental revenues are accounted for under ASC 840. The Company continues to recognize rental revenue from tenants on a straight-line basis over the lease term when collectability is probable and the tenant has taken possession of or controls the physical use of the leased asset. The Company recognizes tenant recoveries related to reimbursement of real estate taxes, insurance, repairs and maintenance, and other operating expenses are recognized as revenue in the period during which the applicable expenses are incurred. The reimbursements are recognized and presented gross, as the Company is generally the primary obligor with respect to purchasing goods and services from third-party suppliers, has discretion in selecting the supplier and bears the associated credit risk. Other tenant-related revenues includes parking stipulated in lease agreements as must-take parking rentals. These revenues are recognized over the term of the lease. Ancillary revenues and other revenues have been accounted for under ASC 606 since the Company adopted this standard on January 1, 2018. These revenues have single performance obligations and are recognized at the point in time when services are rendered. The following table summarizes the Company’s revenue streams that are accounted for under ASC 606: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Ancillary revenues $ 7,505 $ 6,135 $ 19,473 $ 15,541 Other revenues $ 9,686 $ 7,083 $ 21,400 $ 18,357 Studio-related tenant recoveries (1) $ 744 N/A $ 1,739 N/A _________________ 1. Studio-related tenant recoveries are accounted for under ASC 606 effective January 1, 2019. The following table summarizes the Company’s receivables that are accounted for under ASC 606: September 30, 2019 December 31, 2018 Ancillary revenues $ 2,835 $ 3,752 Other revenues $ 2,229 $ 959 Studio-related tenant recoveries (1) $ 9 N/A _________________ 1. Studio-related tenant recoveries are accounted for under ASC 606 effective January 1, 2019. In regards to sale of real estate, the Company applies certain recognition and measurement principles in accordance with ASC 606. The Company is required to evaluate the sales of real estate based on transfer of control. If a real estate sale contract includes ongoing involvement with the sold property by the seller, the seller must evaluate each promised good or service under the contract to determine whether it represents a performance obligation, constitutes a guarantee or prevents the transfer of control. The timing and pattern of revenue recognition might change as it relates to gains on sale of real estate if the sale includes continued involvement that represents a separate performance obligation. Recently Issued Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Update (“ASU”). The following ASUs were adopted by the Company in 2019: Standard Description Effect on the Financial Statements or Other Significant Matters ASU 2016-02, Leases (Topic 842) Issued on February 5, 2016, ASU 2016-02 amends the accounting guidance for leases and sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a lease agreement (i.e., lessees and lessors). The Company adopted ASC 842 during the first quarter of 2019 using the modified retrospective transition method with a cumulative adjustment to accumulated deficit. Refer to Lease Accounting section above for details. ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes The amendments in this update permits use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate. The Company adopted this guidance during the first quarter of 2019 using the prospective approach. The adoption did not have an impact on the Consolidated Financial Statements since LIBOR is still in use, however, this is expected to have an impact in later periods once SOFR is adopted. ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) The amendment allows for capitalization of implementation costs incurred in a hosting arrangement that is a service contract. The Company early adopted this guidance during the third quarter of 2019 using the prospective approach. The adoption did not have a material impact on the Consolidated Financial Statements. ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The amendments in this Update also require certain disclosures about stranded tax effects. The Company adopted this guidance during the first quarter of 2019 on a prospective basis. The adoption did not have an impact on the Consolidated Financial Statements. Other Recently Issued ASUs The Company considers the applicability and impact of all ASUs. The following table lists the recently issued ASUs that have not been disclosed in the Company’s 2018 Annual Report on Form 10-K and have not been adopted by the Company. The list excludes those ASUs that are not expected to have a material impact on the Company’s consolidated financial statements. Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters ASU 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief The amendments in this update provide an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. For those entities, the targeted transition relief will increase comparability of financial statement information by providing an option to align measurement methodologies for similar financial assets. Furthermore, the targeted transition relief also may reduce the costs for some entities to comply with the amendments in Update 2016-13 while still providing financial statement users with decision-useful information. For entities that have not yet adopted the amendments in Update 2016-13, the effective date and transition methodology for the amendments in this Update are the same as in Update 2016-13. Therefore, they are effective for fiscal years beginning after December 15, 2019, including interim periods within those years. The Company is currently evaluating the impact of this update. ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments The FASB amended its standards on credit losses, hedging, and recognizing and The adoption dates and methods are as follows per topic: The Company is currently evaluating the impact of this update. In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses: Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial instruments by requiring companies to recognize an allowance for expected losses, rather than incurred losses as required currently by the other-than-temporary impairment model. The accounting standard will apply to our non-real-estate investments and the Company’s receivables related to service revenues. This standard applies to net investments in leases resulting from sales-type or direct financing leases recognized by a lessor and does not apply to the receivables arising from operating leases, which are accounted for under ASC 842. The accounting standard is effective for reporting periods beginning after December 15, 2019, with early adoption permitted, and will be applied as a cumulative adjustment to retained earnings as of the effective date. The effect on the Company’s consolidated financial statements will largely depend on the composition and credit quality of our financial investments and the economic conditions at the time of adoption.

Income Taxes	Income Taxes Hudson Pacific Properties, Inc. has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”), commencing with its taxable year ended December 31, 2010. Provided it continues to qualify for taxation as a REIT, Hudson Pacific Properties, Inc. is generally not subject to corporate level income tax on the earnings distributed currently to its stockholders. The Company has elected, together with certain of its subsidiaries, to treat such subsidiary as a taxable REIT subsidiary (“TRS”) for federal income tax purposes. The Company’s property-owning subsidiaries are limited liability companies and are treated as pass-through entities or disregarded entities (or, in the case of the entities that own the 1455 Market, Hill7 and Ferry Building properties, REITs) for federal income tax purposes. Accordingly, no provision has been made for federal income taxes in the accompanying consolidated financial statements for the activities of these entities. The Company periodically evaluates its tax positions to determine whether it is more likely than not that such positions would be sustained upon examination by a tax authority for all open tax years, as defined by the statute of limitations, based on their technical merits. As of September 30, 2019, the Company has not established a liability for uncertain tax positions. The Company and its TRS file income tax returns with the U.S. federal government and various state and local jurisdictions. The Company and its TRS are no longer subject to tax examinations by tax authorities for years prior to 2014. The Company has assessed its tax positions for all open years, which include 2014 to 2018, and concluded that there are no material uncertainties to be recognized.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The GAAP fair value framework uses a three-tiered approach. Fair value measurements are classified and disclosed in one of the following three categories: • Level 1: unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities; • Level 2: quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and • Level 3: prices or valuation techniques where little or no market data is available that require inputs that are both significant to the fair value measurement and unobservable. The Company’s financial assets and liabilities measured and reported at fair value on a recurring basis include the following as of: September 30, 2019 December 31, 2018 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Derivative assets (1) $ — $ 655 $ — $ 655 $ — $ 16,687 $ — $ 16,687 Derivative liabilities (2) $ — $ (2,741) $ — $ (2,741) $ — $ — $ — $ — Non-real estate investments (1) $ — $ 5,545 $ — $ 5,545 $ — $ 2,713 $ — $ 2,713 ___________ 1.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company has various stock compensation arrangements, which are more fully described in the 2018 Annual Report on Form 10-K. Under the 2010 Incentive Plan, as amended (“2010 Plan”), the Company’s board of directors (“Board”) has the ability to grant, among other things, restricted stock, restricted stock units, operating partnership performance units and performance-based awards. The Board awards restricted shares to non-employee Board members on an annual basis as part of such Board members’ annual compensation and to newly elected non-employee Board members in accordance with the Non-Employee Director Compensation Program. The time-based awards are generally issued in the second quarter, in conjunction with the director’s election to the Board, and the individual share awards vest in equal annual installments over the applicable service vesting period, which is three years. The Board awards time-based restricted shares or time-based operating partnership performance units to certain employees on an annual basis as part of the employees’ annual compensation. These time-based awards are generally issued in the fourth quarter and vest in equal annual installments over the applicable service vesting period, which is generally three years. Additionally, certain awards are subject to a mandatory holding period upon vesting if the grantee is a named executive officer. In December 2015, the compensation committee of the Board (the “Compensation Committee”) awarded a one-time special retention award to certain executives. The grants consist of time-based awards and performance-based awards. The time-based awards vest in equal 25% installments over a four-year period, subject to the participant’s continued employment. The performance-based awards vest over a four-year period, subject to the achievement of applicable performance goals and the participant’s continued employment. The Compensation Committee annually adopts a Hudson Pacific Properties, Inc. Outperformance Program (“OPP Plan”) under the 2010 Plan. With respect to OPP Plan awards granted through 2016, to the extent an award is earned following the completion of a three-year performance period, 50% of the earned award will vest in full at the end of the three-year performance period and 50% of the earned award will vest in equal annual installments over the two years thereafter, subject to the participant’s continued employment. OPP Plan awards are settled in common stock and, in the case of certain executives, in operating partnership performance units. Commencing with the 2017 OPP Plan, the two-year post-performance vesting period was replaced with a two-year mandatory holding period upon vesting. In February 2019, the Compensation Committee adopted the 2019 OPP Plan. The 2019 OPP Plan is substantially similar to the 2018 OPP Plan except for (i) the performance period beginning on January 1, 2019 and ending on December 31, 2021 and (ii) the maximum bonus pool is $28.0 million. The per unit fair value of the grants from the 2019 OPP Plan was estimated on the date of grant using the following assumptions in the Monte Carlo valuation: Assumption Expected price volatility for the Company 22.00% Expected price volatility for the particular REIT index 18.00% Risk-free rate 2.57% Dividend yield 3.00% The following table presents the classification and amount recognized for stock-based compensation related to the Company’s awards: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Expensed stock compensation (1) $ 5,176 $ 4,292 $ 15,393 $ 12,919 Capitalized stock compensation (2) 28 282 92 802 TOTAL STOCK COMPENSATION (3) $ 5,204 $ 4,574 $ 15,485 $ 13,721 _________________ 1.

The gains and losses on the Company’s derivative instruments are reported in the interest expense line item on the Consolidated Statements of Operations. Interest expense was $77.5 million for the nine months ended September 30, 2019. Non-Controlling Interests Common Units in the Operating Partnership Common units of the operating partnership and shares of common stock of the Company have essentially the same economic characteristics, as they share equally in the total net income or loss distributions of the operating partnership. Investors who own common units have the right to cause the operating partnership to repurchase any or all of their common units for cash equal to the then-current market value of one share of common stock or, at the Company’s election, issue shares of the Company’s common stock in exchange for common units on a one-for-one basis. Performance Units in the Operating Partnership Performance units are partnership interests in the operating partnership. Each performance unit awarded will be deemed equivalent to an award of one share of common stock under the 2010 Plan, reducing the availability for other equity awards on a one-for-one basis. Under the terms of the performance units, the operating partnership will revalue its assets for tax purposes upon the occurrence of certain specified events and any increase in valuation from the time of grant until such event will be allocated first to the holders of performance units to equalize the capital accounts of such holders with the capital accounts of common unitholders. Once vested and having achieved parity with common unitholders, performance units generally are convertible into common units in the operating partnership on a one-for-one basis. Current Year Activity The following table summarizes the ownership interest in the operating partnership, excluding unvested restricted units and unvested restricted performance units as of: September 30, 2019 December 31, 2018 Company-owned common units in the operating partnership 154,414,452 154,371,538 Company’s ownership interest percentage 99.5 % 99.6 % Non-controlling units in the operating partnership (1) 720,773 569,045 Non-controlling ownership interest percentage 0.5 % 0.4 % _________________ 1. Represents units held by certain of the Company’s executive officers, directors and outside investors. As of September 30, 2019, this amount represents both common units and performance units of 550,969 and 169,804, respectively. As of December 31, 2018, this amount represents common units of 569,045 . On January 17, 2019, a common unitholder requested the operating partnership repurchase 18,076 common units and the Company elected, in accordance with the limited partnership agreement of the operating partnership, to settle in cash to satisfy the redemption. On March 11, 2019, 169,804 performance units were granted and vested related to the completion of the 2016 OPP performance period. Common Stock Activity The Company has not completed any common stock offerings in 2019. The Company’s at-the-market, or ATM, program permits sales of up to $125.0 million of common stock. The Company did not utilize the ATM program during the nine months ended September 30, 2019. A cumulative total of $20.1 million has been sold as of September 30, 2019. Share Repurchase Program There have been no repurchases in 2019. On March 8, 2018, the Board increased the amount authorized under its share repurchase program to a total of $250.0 million. A cumulative total of $50.0 million has been repurchased as of September 30, 2019. The Company may make repurchases under the program at any time in its discretion, subject to market conditions, applicable legal requirements and other factors. Dividends The Board declared dividends on a quarterly basis and the Company paid the dividends during the quarters in which the dividends were declared. The following table summarizes dividends declared and paid for the periods presented: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Common stock $ 0.25 $ 0.25 $ 0.75 $ 0.75 Common units $ 0.25 $ 0.25 $ 0.75 $ 0.75 Series A preferred units $ 0.3906 $ 0.3906 $ 1.1718 $ 1.1718 Performance units $ 0.25 $ 0.25 $ 0.75 $ 0.75 Payment date September 30, 2019 September 28, 2018 N/A N/A Record date September 20, 2019 September 18, 2018 N/A N/A Taxability of Dividends Earnings and profits, which determine the taxability of distributions to stockholders, may differ from income reported for financial reporting purposes due to the differences for federal income tax purposes in the treatment of loss on extinguishment of debt, revenue recognition, compensation expense and the basis of depreciable assets and estimated useful lives used to compute depreciation.

Segment Reporting

Segment Reporting	9 Months Ended

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting The Company’s reporting segments are based on the Company’s method of internal reporting, which classifies its operations into two reporting segments: (i) office properties and (ii) studio properties. The Company evaluates performance based upon net operating income of the combined properties in each segment. General and administrative expenses and interest expense are not included in segment profit as its internal reporting addresses these items on a corporate level. Asset information by segment is not reported because the Company does not use this measure to assess performance or make decisions to allocate resources, therefore, depreciation and amortization expense is not allocated among segments. The table below presents the operating activity of the Company’s reportable segments: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Office segment Office revenues $ 186,015 $ 161,446 $ 540,920 $ 476,528 Office expenses (66,969) (57,295) (188,680) (164,475) Office segment profit 119,046 104,151 352,240 312,053 Studio segment Studio revenues 22,203 19,252 61,343 53,457 Studio expenses (11,440) (10,511) (32,088) (28,714) Studio segment profit 10,763 8,741 29,255 24,743 TOTAL SEGMENT PROFIT $ 129,809 $ 112,892 $ 381,495 $ 336,796 Segment revenues $ 208,218 $ 180,698 $ 602,263 $ 529,985 Segment expenses (78,409) (67,806) (220,768) (193,189) TOTAL SEGMENT PROFIT $ 129,809 $ 112,892 $ 381,495 $ 336,796 The table below is a reconciliation of the total profit from all segments to net income: Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 2019 2018 2019 2018 Total profit from all segments $ 129,809 $ 112,892 $ 381,495 $ 336,796 General and administrative (17,661) (14,280) (54,099) (46,047) Depreciation and amortization (69,781) (62,224) (207,892) (183,483) Loss from unconsolidated real estate investments (260) — (345) — Interest expense (26,590) (20,131) (77,492) (59,965) Interest income 1,002 418 3,034 493 Transaction-related expenses (331) (165) (459) (283) Unrealized gain on non-real estate investment — — — 928 Gains on sale of real estate 47,100 3,735 47,100 43,337 Impairment loss — — (52,201) — Other (loss) income (333) 25 (258) 748 NET INCOME $ 62,955 $ 20,270 $ 38,883 $ 92,524

Commitments and Contingencies	Commitments and Contingencies Legal From time to time, the Company is party to various lawsuits, claims and other legal proceedings arising out of, or incident to, the ordinary course of business. Management believes, based in part upon consultation with legal counsel, that the ultimate resolution of all such claims will not have a material adverse effect on the Company’s results of operations, financial position or cash flows. As of September 30, 2019, the risk of material loss from such legal actions impacting the Company’s financial condition or results from operations has been assessed as remote. Letters of Credit

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements of the Company and the operating partnership are prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) applicable to interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to the Securities and Exchange Commission (“SEC”) rules and regulations. Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying interim financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. References to number of properties, square feet and credit rating are not covered by the auditor’s review procedures.
Principles of Consolidation	Principles of Consolidation The unaudited interim consolidated financial statements of the Company include the accounts of the Company, the operating partnership and all wholly owned and controlled subsidiaries. The consolidated financial statements of the operating partnership include the accounts of the operating partnership and all wholly owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements. Under the consolidation guidance, the Company first evaluates an entity using the variable interest model, then the voting model. The Company ultimately consolidates all entities that the Company controls through either majority ownership or voting rights, including all variable interest entities (“VIEs”) of which the Company is considered the primary beneficiary. The Company accounts for all other unconsolidated joint ventures using the equity method of accounting. In addition, the Company continually evaluates each legal entity that is not wholly owned for reconsideration based on changing circumstances. VIEs are defined as entities in which equity investors do not have: • the characteristics of a controlling financial interest; • sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties; and/or • the entity is structured with non-substantive voting rights. The entity that consolidates a VIE is known as its primary beneficiary and is generally the entity with both the power to direct the activities that most significantly affect the VIE’s economic performance and the right to receive benefits from the VIE or the obligation to absorb losses of the VIE that could be significant to the VIE. As of September 30, 2019, the Company has determined its operating partnership and five joint ventures met the definition of a VIE. Four of the joint ventures are consolidated and one of the joint ventures is unconsolidated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of commitments and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to acquiring, developing and assessing the carrying values of its real estate properties, determining the incremental borrowing rate used in the present value calculations of its new or modified operating lessee agreements, its accrued liabilities and its performance-based equity compensation awards. The Company bases its estimates on historical experience, current market conditions and various other assumptions that are believed to be reasonable under the circumstances. Actual results could materially differ from these estimates.
Lessee Accounting	Lessee Accounting The Company determines if an arrangement is a lease at inception. The Company’s operating lease agreements relate to ground lease assets and are reflected in operating lease ROU assets and operating lease liabilities on the Consolidated Balance Sheets.
Lessor Accounting	Lessor Accounting As a lessor, the Company’s recognition of revenue remained consistent with previous guidance, apart from the narrower definition of initial direct costs that can be capitalized. With the election of the lessor practical expedient, the presentation of revenues on the Consolidated Statement of Operations has changed to reflect a single lease component that combines rental, tenant recoveries, and other tenant-related revenues for the office portfolio. For the Company’s rentals at the studio properties, total lease consideration is allocated to lease and non-lease components on a relative standalone basis. The recognition of revenues related to lease components is governed by ASC 842, while revenue related to non-lease components is subject to ASC 606, Revenue from Contracts with Customers (“ASC 606”). The new standard defines initial direct costs as only the incremental costs of signing a lease. Internal direct compensation costs and external legal fees related to the execution of successful lease agreements that no longer meet the definition of initial direct costs under ASC 842 are accounted for as office operating expense or studio operating expense in the Company’s Consolidated Statements of Operations. Additionally, the Company may elect the practical expedients only for leases that have commenced before the effective date of the adoption of ASC 842. As a result of the adoption, the Company recognized $1.8 million as a cumulative adjustment to accumulated deficit for costs associated with leases that have not commenced as of January 1, 2019, that were previously capitalized and no longer meet the definition of initial direct costs in accordance with ASC 842. The Company recognized $0.3 million as cumulative adjustments to accumulated deficit related to other transition adjustments.
Revenue Recognition	Revenue Recognition The Company has compiled an inventory of its sources of revenues and has identified the following material revenue streams: (i) rental revenues (ii) tenant recoveries and other tenant-related revenues (iii) ancillary revenues (iv) other revenues and (v) sale of real estate. Revenue Stream Components Financial Statement Location (1) Rental revenues Office rentals, stage rentals and storage rentals Office and studio segments: rental Tenant recoveries and other tenant-related revenues Reimbursement of real estate taxes, insurance, repairs and maintenance, other operating expenses and must-take parking revenues Office segment: rental Ancillary revenues Revenues derived from tenants’ use of lighting, equipment rental, power, HVAC and telecommunications (i.e., telephone and internet) Studio segment: service revenues and other Other revenues Parking revenue that is not associated with lease agreements, management fees, and other Office and studio segments: service revenues and other Sale of real estate Gains on sales derived from cash consideration less cost basis Gains on sale of real estate _________________ 1. The financial statement locations stated above are for the nine months ended September 30, 2019, after the adoption of ASC 842, and do not reflect the locations for the nine months ended September 30, 2018. The Company’s 2018 rental revenues are accounted for under ASC 840. The Company continues to recognize rental revenue from tenants on a straight-line basis over the lease term when collectability is probable and the tenant has taken possession of or controls the physical use of the leased asset. The Company recognizes tenant recoveries related to reimbursement of real estate taxes, insurance, repairs and maintenance, and other operating expenses are recognized as revenue in the period during which the applicable expenses are incurred. The reimbursements are recognized and presented gross, as the Company is generally the primary obligor with respect to purchasing goods and services from third-party suppliers, has discretion in selecting the supplier and bears the associated credit risk. Other tenant-related revenues includes parking stipulated in lease agreements as must-take parking rentals. These revenues are recognized over the term of the lease. Ancillary revenues and other revenues have been accounted for under ASC 606 since the Company adopted this standard on January 1, 2018. These revenues have single performance obligations and are recognized at the point in time when services are rendered. The following table summarizes the Company’s revenue streams that are accounted for under ASC 606: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Ancillary revenues $ 7,505 $ 6,135 $ 19,473 $ 15,541 Other revenues $ 9,686 $ 7,083 $ 21,400 $ 18,357 Studio-related tenant recoveries (1) $ 744 N/A $ 1,739 N/A _________________ 1. Studio-related tenant recoveries are accounted for under ASC 606 effective January 1, 2019. The following table summarizes the Company’s receivables that are accounted for under ASC 606: September 30, 2019 December 31, 2018 Ancillary revenues $ 2,835 $ 3,752 Other revenues $ 2,229 $ 959 Studio-related tenant recoveries (1) $ 9 N/A _________________ 1. Studio-related tenant recoveries are accounted for under ASC 606 effective January 1, 2019. In regards to sale of real estate, the Company applies certain recognition and measurement principles in accordance with ASC 606. The Company is required to evaluate the sales of real estate based on transfer of control. If a real estate sale contract includes ongoing involvement with the sold property by the seller, the seller must evaluate each promised good or service under the contract to determine whether it represents a performance obligation, constitutes a guarantee or prevents the transfer of control. The timing and pattern of revenue recognition might change as it relates to gains on sale of real estate if the sale includes continued involvement that represents a separate performance obligation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Update (“ASU”). The following ASUs were adopted by the Company in 2019: Standard Description Effect on the Financial Statements or Other Significant Matters ASU 2016-02, Leases (Topic 842) Issued on February 5, 2016, ASU 2016-02 amends the accounting guidance for leases and sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a lease agreement (i.e., lessees and lessors). The Company adopted ASC 842 during the first quarter of 2019 using the modified retrospective transition method with a cumulative adjustment to accumulated deficit. Refer to Lease Accounting section above for details. ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes The amendments in this update permits use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate. The Company adopted this guidance during the first quarter of 2019 using the prospective approach. The adoption did not have an impact on the Consolidated Financial Statements since LIBOR is still in use, however, this is expected to have an impact in later periods once SOFR is adopted. ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) The amendment allows for capitalization of implementation costs incurred in a hosting arrangement that is a service contract. The Company early adopted this guidance during the third quarter of 2019 using the prospective approach. The adoption did not have a material impact on the Consolidated Financial Statements. ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The amendments in this Update also require certain disclosures about stranded tax effects. The Company adopted this guidance during the first quarter of 2019 on a prospective basis. The adoption did not have an impact on the Consolidated Financial Statements. Other Recently Issued ASUs The Company considers the applicability and impact of all ASUs. The following table lists the recently issued ASUs that have not been disclosed in the Company’s 2018 Annual Report on Form 10-K and have not been adopted by the Company. The list excludes those ASUs that are not expected to have a material impact on the Company’s consolidated financial statements. Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters ASU 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief The amendments in this update provide an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. For those entities, the targeted transition relief will increase comparability of financial statement information by providing an option to align measurement methodologies for similar financial assets. Furthermore, the targeted transition relief also may reduce the costs for some entities to comply with the amendments in Update 2016-13 while still providing financial statement users with decision-useful information. For entities that have not yet adopted the amendments in Update 2016-13, the effective date and transition methodology for the amendments in this Update are the same as in Update 2016-13. Therefore, they are effective for fiscal years beginning after December 15, 2019, including interim periods within those years. The Company is currently evaluating the impact of this update. ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments The FASB amended its standards on credit losses, hedging, and recognizing and The adoption dates and methods are as follows per topic: The Company is currently evaluating the impact of this update. In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses: Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial instruments by requiring companies to recognize an allowance for expected losses, rather than incurred losses as required currently by the other-than-temporary impairment model. The accounting standard will apply to our non-real-estate investments and the Company’s receivables related to service revenues. This standard applies to net investments in leases resulting from sales-type or direct financing leases recognized by a lessor and does not apply to the receivables arising from operating leases, which are accounted for under ASC 842. The accounting standard is effective for reporting periods beginning after December 15, 2019, with early adoption permitted, and will be applied as a cumulative adjustment to retained earnings as of the effective date. The effect on the Company’s consolidated financial statements will largely depend on the composition and credit quality of our financial investments and the economic conditions at the time of adoption.

The Company adopted ASC 842 during the first quarter of 2019 using the modified retrospective transition method with a cumulative adjustment to accumulated deficit. Refer to Lease Accounting section above for details. ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes The amendments in this update permits use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate. The Company adopted this guidance during the first quarter of 2019 using the prospective approach. The adoption did not have an impact on the Consolidated Financial Statements since LIBOR is still in use, however, this is expected to have an impact in later periods once SOFR is adopted. ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) The amendment allows for capitalization of implementation costs incurred in a hosting arrangement that is a service contract. The Company early adopted this guidance during the third quarter of 2019 using the prospective approach. The adoption did not have a material impact on the Consolidated Financial Statements. ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The amendments in this Update also require certain disclosures about stranded tax effects. The Company adopted this guidance during the first quarter of 2019 on a prospective basis. The adoption did not have an impact on the Consolidated Financial Statements. Other Recently Issued ASUs The Company considers the applicability and impact of all ASUs. The following table lists the recently issued ASUs that have not been disclosed in the Company’s 2018 Annual Report on Form 10-K and have not been adopted by the Company. The list excludes those ASUs that are not expected to have a material impact on the Company’s consolidated financial statements. Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters ASU 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief The amendments in this update provide an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. For those entities, the targeted transition relief will increase comparability of financial statement information by providing an option to align measurement methodologies for similar financial assets. Furthermore, the targeted transition relief also may reduce the costs for some entities to comply with the amendments in Update 2016-13 while still providing financial statement users with decision-useful information. For entities that have not yet adopted the amendments in Update 2016-13, the effective date and transition methodology for the amendments in this Update are the same as in Update 2016-13. Therefore, they are effective for fiscal years beginning after December 15, 2019, including interim periods within those years. The Company is currently evaluating the impact of this update. ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments The FASB amended its standards on credit losses, hedging, and recognizing and The adoption dates and methods are as follows per topic: The Company is currently evaluating the impact of this update.
