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. 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, 2018 . The interim consolidated financial statements should be read in conjunction with the consolidated financial statements in the 2017 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 cost or 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 March 31, 2018 , the Company has determined that four joint ventures and our operating partnership met the definition of a VIE. Three of the joint ventures are consolidated entities and one joint venture is a non-consolidated entity. Consolidated Entities As of March 31, 2018 , the operating partnership has determined that three 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 Westside Pavilion (1) 75.0 % _________________ (1) As of March 31, 2018, this joint venture was formed but no significant contributions of cash or property have been made by the partners. On March 1, 2018, the Company entered into a joint venture agreement with Macerich WSP, LLC (“Macerich”) to form HPP-MAC WSP, LLC (“HPP-MAC JV”) to redevelop Westside Pavilion, a shopping mall in West Los Angeles, into approximately 500,000 square feet of state-of-the-art creative office space, with approximately 100,000 square feet of existing retail and entertainment space. The HPP-MAC JV is held 75% by the Company and 25% by Macerich, with the Company serving as the managing member and developer. As of March 31, 2018 , the assets held by the HPP-MAC JV include pre-development costs and the initial contributions from the members. Pursuant to the joint venture agreement, it is anticipated that the Company and Macerich will enter into a contribution agreement within a year to contribute Westside Pavilion to the joint venture. The contribution is valued at approximately $190.0 million before certain credits, prorations, closing costs and debt assumption. Total costs of the HPP-MAC JV will be funded 75% by the Company and 25% by Macerich. If either party defaults on its obligation to contribute to the joint venture, the defaulting party is required to pay a $25.0 million fee to the other member. The joint venture agreement lacks substantive participating or kick-out rights and is therefore a VIE. The Company, through its subsidiaries, has the right to (i) receive benefits and absorb losses and (ii) has the power to direct the activities that most significantly affect the joint venture. As of March 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 VIEs. Non-consolidated Entities On June 16, 2016, the Company entered into a joint venture to co-originate a loan secured by land in Santa Clara, California. The assets of the joint venture consist of notes receivable. As of March 31, 2018 , the Company has determined it is not the primary beneficiary of the joint venture that meets the definition of a VIE. Due to its significant influence over the non-consolidated entity, the Company accounts for it 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. The Company’s net equity investment is reflected within prepaid expenses and other assets on the Consolidated Balance Sheets which represents the Company’s maximum exposure for loss. The Company’s share of net income or loss from the entity is included within other income on the Consolidated Statements of Operations. The Company owns 21% of the non-consolidated entity. 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, 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. 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 (iii) ancillary revenues (iv) guest parking revenues and (v) sale of real estate. Revenue Stream Components Financial Statement Location Rental revenues Office rentals, stage rentals and storage rentals Office and Studio Segments: rental Tenant recoveries Reimbursement of real estate taxes, insurance, repairs and maintenance, other operating expenses and monthly parking revenues Office Segment: tenant recoveries and parking and other Studio Segment: tenant recoveries and other property-related revenue Ancillary revenues Revenues derived from tenants’ use of lighting, equipment rental, power, HVAC and telecommunications (i.e., telephone and internet) Studio Segment: other property-related revenue Guest parking revenues Parking revenue that is not associated with lease agreements Office Segment: parking and other Sale of real estate Gains on sales derived from cash consideration less cost basis Gains on sale of real estate Currently rental revenues are accounted for under ASC 840, Leases . Rental revenues will be accounted for under ASC 842, Leases (“ASC 842”), which the Company plans to adopt on January 1, 2019. Currently tenant recoveries are accounted for under ASC 605, Revenue Recognition (“ASC 605”). Tenant recoveries will be accounted for under ASC 606, Revenue from Contracts with Customers (“ASC 606”), on January 1, 2019, when the Company adopts ASC 842. Under the current ASC 842 guidance, the Company would be required to classify its tenant recoveries into lease and non-lease components. On March 28, 2018, the FASB agreed to issue an amendment to ASC 842, which if elected, permits the Company to classify tenant recoveries as a single lease component and accounted for with rental revenues in the Consolidated Statement of Operations. Please refer to our Update on ASC 842 implementation section below for details. Ancillary revenues and guest parking revenues have been accounted for under ASC 606 since the Company adopted this standard on January 1, 2018. This standard requires the Company to recognize revenues based on a five-step model and will result in the consideration being recognized once all performance obligations are satisfied. The timing and pattern of revenue recognition as it relates to ancillary revenues and guest parking revenues have not changed from those under ASC 605. Sale of real estate has been accounted for under ASC 610, Other Income , since the Company adopted this standard on January 1, 2018. This standard requires the Company to apply certain recognition and measurement principles in ASC 606 when it derecognizes nonfinancial assets and in substance nonfinancial assets, and the counterparty is not a customer. This is the case for the Company's sales of real estate, and therefore, 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 by the seller with the sold property, 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 of 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 (the “FASB”) in the form of Accounting Standards Update (“ASU”). The following ASUs were adopted by the Company in 2018: Standard Description Effect on the Financial Statements or Other Significant Matters ASU 2018-04, Investments—Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273 (SEC Update) ASU 2018-03, Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ASU 2016-01, Financial Instruments— Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities The guidance no longer allows the use of cost method of accounting for equity instruments that do not have a readily determinable fair value and Companies are now required to measure equity investments at fair value through net income. Companies are permitted to elect a measurement alternative that allows for measuring equity instruments at cost, less any impairment, plus or minus changes resulting from observable price changes, adjusted as of the date that an observable transaction takes place, rather than report date. For equity investments that do not have a readily determinable fair value, this guidance is adopted prospectively for all investments that exist as of the date of adoption. The guidance allows entities to use a prospective transition approach only for securities they elect to measure using the measurement alternative. The Company adopted this guidance during Q1 2018 using the prospective approach. The Company has elected to measure our equity instruments using the measurement alternative. Please see Note 12 for details. ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Therefore, a cumulative effect adjustment related to elimination of ineffectiveness measurement is required to be recorded to the opening balance of retained earnings as of the beginning of the fiscal year of adoption for cash flow hedge. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. This guidance must be applied using a modified retrospective approach. The Company adopted this guidance during Q1 2018 using the modified retrospective approach. As a result of the adoption, the concept of ineffectiveness from an accounting perspective is eliminated. Subsequent changes in fair value for a hedging instrument that has been designated and qualifies as a cash flow hedge will be recognized as a component in other comprehensive income. Additionally, the Company eliminated any previously recorded ineffectiveness with a cumulative effect adjustment. Please see Note 9 for details. ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting The guidance clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. This guidance must be applied prospectively. The Company adopted this guidance during Q1 2018 on a prospective basis. The adoption did not have an impact on the Consolidated Financial Statements. Standard Description Effect on the Financial Statements or Other Significant Matters ASU 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets The guidance updates the definition of an in substance nonfinancial asset and clarifies the scope of ASC 610-20 on the sale or transfer of nonfinancial assets to noncustomers, including partial sales. It also clarifies the derecognition guidance for nonfinancial assets to conform with the new revenue recognition standard. Either a full or modified retrospective approach can be applied. The Company adopted this guidance during Q1 2018 using the modified retrospective approach. The Company has not had variable consideration in our sale of real estate, or partial sales of nonfinancial assets or contribution of a nonfinancial asset to form a joint venture with retained noncontrolling interest, therefore the guidance does not currently impact the Company. ASU 2014-09, Revenue from Contracts with Customers amended by ASU 2016-08, Revenue from Contracts with Customers—Principal versus Agent Considerations (Reporting Revenue Gross versus Net) Issued on May 28, 2014, ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenues arising from contracts with customers and specifically notes that lease contracts with customers are a scope exception. Issued on March 17, 2016, ASU 2016-08 clarifies certain aspects of the principal-versus-agent guidance in its new revenue recognition standard related to the determination of whether an entity is a principal-versus-agent and the determination of the nature of each specified good or service. The guidance provides for practical expedients associated with the determination of whether a significant financing component exists and the expedient for recording an immediate expense for certain incremental costs of obtaining a contract with a customer. The Company adopted this guidance during Q1 2018 using the modified retrospective approach and is using the practical expedients associated with expensing incremental costs of obtaining a contract with a customer with terms of one year or less. The adoption of this ASU did not result in any changes with respect to the timing and pattern of revenue recognition. Please refer to the revenue recognition paragraph above for the additional disclosures. Update on ASC 842 implementation On February 25, 2016, the FASB issued ASU 2016-02, Leases , to amend the accounting guidance for leases and set out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a lease agreement (i.e., lessees and lessors). This ASU is effective for annual reporting periods (including interim periods) beginning after December 15, 2018. A modified retrospective approach must be applied for leases that exist or are entered into after January 1, 2017, the beginning of the earliest comparative period presented in the 2019 consolidated financial statements, with a cumulative adjustment to the opening balance of retained earnings (accumulated deficit) on January 1, 2017, and restatement of the amounts presented prior to January 1, 2019. On March 28, 2018, the FASB agreed to issue an amendment to ASU 842 that would provide an entity the optional transition method to initially account for the impact of the adoption with a cumulative adjustment to retained earnings (accumulated deficit) on the effective date of the ASU, January 1, 2019, rather than January 1, 2017, which would eliminate the need to restate amounts presented prior to January 1, 2019. This guidance requires all lessees to record a lease liability at lease inception, with a corresponding right-of-use asset, except for short-term leases. Lessor accounting will not be fundamentally changed. ASC 842 provides practical expedients that allow entities to not (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. The Company plans to adopt the standard on January 1, 2019 and expects to elect the use of practical expedients. If the proposed amendment to ASU 842 is adopted, the Company would elect the transition method for adoption as described above. Lessor Accounting The Company recognized rental revenues and tenant recoveries of $161.7 million and $158.3 million for the three months ended March 31, 2018 and March 31, 2017 . This ASU requires companies to identify lease and non-lease components of a lease agreement. Lease components relate to the right to use the leased asset and non-lease components relate to payments for goods or services that are transferred separately from the right to use the underlying asset. Total lease consideration is allocated to lease and non-lease components on a relative standalone basis. The recognition of revenues related to lease components will be governed by ASC 842 while revenue related to non-lease components will be subject to ASC 606. Under current accounting standards, the Company recognizes rental revenue from tenants on a straight-line basis over the lease term when collectability is reasonably assured and the tenant has taken possession or controls the physical use of the leased asset. 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, have discretion in selecting the supplier and bear the associated credit risk. In the March 28, 2018 FASB meeting, the FASB agreed to issue an amendment to ASC 842 which would allow lessors to elect, as a practical expedient, not to allocate the total consideration to lease and non-lease components based on their relative standalone selling prices. Once the amendment is adopted, this practical expedient will allow lessors 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 and, the combined single lease component would be classified as an operating lease. The Company has not completed its analysis of this ASU. Once the amendments discussed during the March 28, 2018 FASB meeting are issued, adopted and elected, tenant recoveries that qualify as non-lease components will be combined under a single lease component presentation. The ASU also requires lessors to capitalize only those costs that are defined as initial direct costs. Under the current accounting standards, the Company capitalizes initial direct and indirect leasing costs. During the three months ended March 31, 2018 and March 31, 2017 , the Company capitalized $1.8 million and $1.4 million of indirect leasing costs, respectively. Under this new ASU, these costs will be expensed as incurred. Lessee Accounting As of March 31, 2018 , the future undiscounted minimum lease payments under the Company’s ground leases totaled $449.3 million . This guidance requires lessees to record a lease liability at lease inception, with a corresponding right-of-use asset, except for short-term leases. The Company continues to evaluate the amount of right-of-use asset and lease liability that will ultimately be recorded with respect to its ground lease agreements, where it is the lessee. 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 2017 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 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 The amendments in this update permit an entity to elect an optional transition practical expedient to not evaluate under Topic 842 land easements that exist or expired before the entity’s adoption of Topic 842 and that were not previously accounted for as leases under Topic 840. An entity that elects this practical expedient should apply the practical expedient consistently to all of its existing or expired land easements that were not previously accounted for as leases under Topic 840. Once an entity adopts Topic 842, it should apply that Topic prospectively to all new (or modified) land easements to determine whether the arrangement should be accounted for as a lease. The effective date and transition requirements are the same as that in Update 2016-02 (Effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years.) The Company is currently evaluating the impact of this update.

Real Estate [Abstract]
Investment in Real Estate	Investment in Real Estate Real estate held for investment The following table summarizes the Company’s investment in real estate, at cost as of: March 31, 2018 December 31, 2017 Land $ 1,302,907 $ 1,302,907 Building and improvements 4,476,124 4,480,993 Tenant improvements 425,624 411,706 Furniture and fixtures 8,371 8,608 Property under development 286,367 219,227 Investment in real estate, at cost (1) $ 6,499,393 $ 6,423,441 _____________ (1) Excludes balances related to properties that have been classified as held for sale. Acquisitions The Company’s acquisitions are accounted for using the acquisition method. The results of operations for each of these acquisitions are included in the Company’s Consolidated Statements of Operations from the date of acquisition. The Company evaluates each acquisition to determine if the integrated set of assets and activities acquired meet the definition of a business and need to be accounted for as a business combination in accordance with ASC 805, Business Combinations . An integrated set of assets and activities would fail to qualify as a business if either (i) substantially all of the fair value of the gross assets acquired is concentrated in either a single identifiable asset or a group of similar identifiable assets or (ii) the integrated set of assets and activities is lacking, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs (i.e., revenue generated before and after the transaction). An acquired process is considered substantive if (i) the process includes an organized workforce (or includes an acquired contract that provides access to an organized workforce) that is skilled, knowledgeable and experienced in performing the process, (ii) the process cannot be replaced without significant cost, effort, or delay or (iii) the process is considered unique or scarce. The Company assesses fair value based on Level 2 and Level 3 inputs within the fair value framework, which includes estimated cash flow projections that utilize appropriate discount, capitalization rates, renewal probability and available market information, which includes market rental rate and market rent growth rates. Estimates of future cash flows are based on a number of factors, including historical operating results, known and anticipated trends and market and economic conditions. The fair value of tangible assets of an acquired property considers the value of the property as if it were vacant. The fair value of acquired “above- and below-” market leases are based on the estimated cash flow projections utilizing discount rates that reflect the risks associated with the leases acquired. The amount recorded is based on the present value of the difference between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management’s estimate of fair market lease rates for each in-place lease, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the extended below-market term for any leases with below-market renewal options. Other intangible assets acquired include amounts for in-place lease values that are based on the Company’s evaluation of the specific characteristics of each tenant’s lease. Factors considered include estimates of carrying costs during hypothetical expected lease-up periods, market conditions and costs to execute similar leases. In estimating carrying costs, the Company includes estimates of lost rents at market rates during the hypothetical expected lease-up periods, which are dependent on local market conditions. In estimating costs to execute similar leases, the Company considers leasing commissions, legal and other related costs. The Company had no acquisitions during the three months ended March 31, 2018 . Dispositions The following table summarizes the properties sold during the three months ended March 31, 2018 . These properties were non-strategic assets to the Company’s portfolio and were classified as held for sale as of December 31, 2017 : Property Month of Disposition Square Feet Sales Price (1) (in millions) 2600 Campus Drive (building 6 of Peninsula Office Park) January 2018 63,050 $ 22.5 Embarcadero Place January 2018 197,402 136.0 2180 Sand Hill March 2018 45,613 82.5 Total dispositions 306,065 $ 241.0 _________________ (1) Represents gross sales price before certain credits, prorations and closing costs. These dispositions met the criteria in ASC 610 for recognizing gains of $37.7 million for the three months ended March 31, 2018 , which is included in the gains on sale of real estate line item in the Consolidated Statements of Operations. Held for Sale In December 2017, the Company entered into an agreement to sell its 9300 Wilshire property for $13.8 million (before certain credits, prorations and closing costs).

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 one 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 treated as pass-through entities or disregarded entities (or, in the case of the entities that own the 1455 Market and Hill7 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 March 31, 2018 , 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 2013. The Company has assessed its tax positions for all open years, which include 2013 to 2017, 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. In September 2016, the Company entered into an agreement to receive shares of a nonpublic company in lieu of rental and tenant recovery revenues that were valued at $1.8 million . The shares were accounted for under the cost method of accounting as there was no readily determinable fair value. The investment in the shares has been accounted for under ASC 825-10, Recognition and Measurement of Financial Assets and Financial Liabilities , since the Company adopted ASU 2016-01 on January 1, 2018, at which point the Company elected the measurement alternative. This standard requires the Company to mark the investment in shares to fair value, which are based on recent transactions. There have been no other transactions since the Company obtained its shares in 2016 and therefore there have been no adjustments to the carrying value. The Company’s financial assets and liabilities measured and reported at fair value on a recurring basis include the following as of: March 31, 2018 December 31, 2017 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Derivative assets (1) $ — $ 21,922 $ — $ 21,922 $ — $ 12,586 $ — $ 12,586 Derivative liabilities — — — — — 265 — 265 _________________ (1) Included in the prepaid expenses and other assets line item on the Consolidated Balance Sheets. Other Financial Instruments The carrying values of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued liabilities are reasonable estimates of fair value, using Level 1 inputs, because of the short-term nature of these instruments. Fair values for notes payable are estimates based on rates currently prevailing for similar instruments of similar maturities using Level 2 inputs. The table below represents the carrying value and fair value of the Company’s notes payable as of: March 31, 2018 December 31, 2017 Carrying Value Fair Value Carrying Value Fair Value Unsecured notes payable (1)(2) $ 1,894,296 $ 1,856,896 1,974,278 $ 1,960,560 Secured notes payable 365,782 356,935 464,311 458,441 _________________ (1) Amounts represent notes payable excluding net deferred financing costs.

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 to employees on an annual basis as part of the employees’ annual compensation. The time-based awards are generally issued in the fourth quarter and the individual share awards vest in equal annual installments over the applicable service vesting period, which is generally three years. Additionally, certain restricted share 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 (“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. An award under the OPP Plan is ultimately earned to the extent the Company outperforms a predetermined total shareholder return (“TSR”) goal and/or achieves goals with respect to the outperformance of its peers in a particular REIT index. The ultimate aggregate award cannot exceed the predetermined maximum bonus pool. OPP Plan awards granted are settled in common stock and in the case of certain executives, in performance units in our operating partnership. With respect to OPP Plan awards granted prior to 2017, 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 25% of the earned award will vest in equal annual installments over the two years thereafter, subject to the participant’s continued employment. 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 2018, the Compensation Committee adopted the 2018 OPP Plan. The 2018 OPP Plan is substantially similar to the 2017 OPP Plans except for (i) the performance period beginning on January 1, 2018 and ending on December 31, 2020, (ii) the maximum bonus pool is $25.0 million , (iii) the relative comparison index is the SNL US Office REIT index, (iv) the absolute TSR hurdle will be 21% (or 7% per annum) and (v) adjusted the sliding scale low return factor so that relative TSR pool can only be reduced by 75% under this feature. The per unit fair value of the 2018 OPP award granted was estimated on the date of grant using the following assumptions in the Monte Carlo valuation: Assumption Expected price volatility for the Company 20.00% Expected price volatility for the particular REIT index 18.00% Risk-free rate 2.37% Dividend yield 2.90% The following table presents the classification and amount recognized for stock-based compensation related to the Company’s awards: Three Months Ended March 31, 2018 2017 Expensed stock compensation (1) $ 4,338 $ 3,902 Capitalized stock compensation (2) 232 199 Total stock compensation (3) $ 4,570 $ 4,101 _________________ (1) Amounts are recorded in general and administrative expenses in the Consolidated Statements of Operations.

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. The following table summarizes the ownership of common units, excluding unvested restricted units as of: March 31, 2018 December 31, 2017 Company-owned common units in the operating partnership 155,626,055 155,602,508 Company’s ownership interest percentage 99.6 % 99.6 % Non-controlling common units in the operating partnership (1) 569,045 569,045 Non-controlling ownership interest percentage (1) 0.4 % 0.4 % _________________ (1) Represents common units held by certain of the Company’s executive officers and directors, certain of their affiliates and other outside investors . 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. Subject to any agreed upon exceptions, once vested and having achieved parity with common unitholders, performance units are convertible into common units in the operating partnership on a one -for-one basis. 6.25% Series A cumulative redeemable preferred units of the operating partnership There are 407,066 Series A preferred units of partnership interest in the operating partnership, or Series A preferred units, which are not owned by the Company. These Series A preferred units are entitled to preferential distributions at a rate of 6.25% per annum on the liquidation preference of $25.00 per unit and became convertible at the option of the holder into common units or redeemable into cash or, at the Company’s election, exchangeable for registered shares of common stock after June 29, 2013. For a description of the conversion and redemption rights of the Series A preferred units, please see “Description of the Partnership Agreement of Hudson Pacific Properties, L.P. — Material Terms of Our Series A Preferred Units” in the Company’s June 23, 2010 Prospectus. Common Stock Activity The Company has not completed any common stock offerings in 2018. 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 three months ended March 31, 2018 . A cumulative total of $20.1 million has been sold as of March 31, 2018 . Share repurchase program On January 20, 2016, the Board authorized a share repurchase program to buy up to $100.0 million of the outstanding common stock of Hudson Pacific Properties, Inc., which the Board has increased up to a total of $250.0 million on March 8, 2018. No share repurchases have been made as of March 31, 2018 . Dividends During the first quarter of 2018 , the Company declared dividends on its common stock and non-controlling interest in common units in the operating partnership of $0.25 per share and unit. The Company also declared dividends on its Series A preferred units of $0.3906 per unit. The first quarter dividends were paid on March 29, 2018 to stockholders and unitholders of record on March 19, 2018 . 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.

Disposal of Pinnacle I and Pinnacle II to certain affiliates of Blackstone On November 16, 2017, the consolidated joint venture that owned Pinnacle I and Pinnacle II sold the properties to certain affiliates of Blackstone for $350.0 million , before credits, prorations and closing costs, including the assumption of $216.0 million of secured notes payable. Michael Nash, a director on the Board, is a senior managing director of an affiliate of Blackstone. Disposal of 222 Kearny to certain affiliates of Farallon Funds On February 14, 2017, the Company sold its 222 Kearny property to a joint venture, a partner of which is an affiliate of the Farallon Funds. Richard B. Fried, a director on the Board, is a managing member of the Farallon Funds. JMG Capital Lease at 11601 Wilshire JMG Capital Management LLC leases approximately 6,638 square feet at the Company’s 11601 Wilshire property pursuant to an eight -year lease at an aggregate rate of approximately $279 thousand annualized rent per year. Jonathan M. Glaser, a director on the Board, is the founder and managing member of JMG Capital Management LLC. JMG Capital Management LLC was a tenant of the property at the time it was purchased by the Company in 2016. During 2017, JMG Capital Management LLC assigned the lease to a third party and as a result is no longer a lessee at our 11601 Wilshire property as of December 31, 2017. Agreement Related to EOP Acquisition On April 1, 2015, the Company completed the EOP Acquisition from certain affiliates of Blackstone, which consisted of 26 high-quality office assets totaling approximately 8.2 million square feet and two development parcels located throughout the Northern California region. The total consideration paid for the EOP Acquisition before certain credits, prorations and closing costs, included a cash payment of $1.75 billion and an aggregate of 63,474,791 shares of common stock of Hudson Pacific Properties, Inc. and common units in the operating partnership. In connection with the EOP Acquisition, the Company, the operating partnership and Blackstone entered into a stockholders agreement, which conferred Blackstone certain rights, including the right to nominate up to three of the Company’s directors. Additionally, the Company entered into a registration rights agreement with Blackstone providing for customary registration rights with respect to the equity consideration paid in the EOP Acquisition. Following a common stock offering and common unit repurchase on January 10, 2017, the stockholders agreement and the registration rights agreement automatically terminated on that date. Common Stock Offerings and Common Unit Redemptions On January 10, 2017, the Company, Blackstone and the Farallon Funds completed a public offering of 18,673,808 shares of common stock, consisting of 8,881,575 shares offered by the Company and 9,792,233 shares offered by the selling stockholders. The offering generated net proceeds for the Company and the selling stockholders of approximately $310.9 million and $342.7 million , respectively, before expenses. The Company used the net proceeds that it received from the offering to redeem 8,881,575 common units held by Blackstone and the Farallon Funds. The Company did not receive any proceeds from the sale of the common stock by the selling stockholders in the offerings described above but it paid approximately half of the expenses of the offerings with respect to the shares of common stock sold by the Farallon Funds and all of the expenses with respect to the shares of common stock sold by Blackstone, in each case, other than underwriting discounts, which were borne by the selling stockholders.

Summary of Significant Accoun28

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
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. 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, 2018 . The interim consolidated financial statements should be read in conjunction with the consolidated financial statements in the 2017 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 cost or 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 March 31, 2018 , the Company has determined that four joint ventures and our operating partnership met the definition of a VIE. Three of the joint ventures are consolidated entities and one joint venture is a non-consolidated entity.
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, 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.
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 (iii) ancillary revenues (iv) guest parking revenues and (v) sale of real estate. Revenue Stream Components Financial Statement Location Rental revenues Office rentals, stage rentals and storage rentals Office and Studio Segments: rental Tenant recoveries Reimbursement of real estate taxes, insurance, repairs and maintenance, other operating expenses and monthly parking revenues Office Segment: tenant recoveries and parking and other Studio Segment: tenant recoveries and other property-related revenue Ancillary revenues Revenues derived from tenants’ use of lighting, equipment rental, power, HVAC and telecommunications (i.e., telephone and internet) Studio Segment: other property-related revenue Guest parking revenues Parking revenue that is not associated with lease agreements Office Segment: parking and other Sale of real estate Gains on sales derived from cash consideration less cost basis Gains on sale of real estate Currently rental revenues are accounted for under ASC 840, Leases . Rental revenues will be accounted for under ASC 842, Leases (“ASC 842”), which the Company plans to adopt on January 1, 2019. Currently tenant recoveries are accounted for under ASC 605, Revenue Recognition (“ASC 605”). Tenant recoveries will be accounted for under ASC 606, Revenue from Contracts with Customers (“ASC 606”), on January 1, 2019, when the Company adopts ASC 842. Under the current ASC 842 guidance, the Company would be required to classify its tenant recoveries into lease and non-lease components. On March 28, 2018, the FASB agreed to issue an amendment to ASC 842, which if elected, permits the Company to classify tenant recoveries as a single lease component and accounted for with rental revenues in the Consolidated Statement of Operations. Please refer to our Update on ASC 842 implementation section below for details. Ancillary revenues and guest parking revenues have been accounted for under ASC 606 since the Company adopted this standard on January 1, 2018. This standard requires the Company to recognize revenues based on a five-step model and will result in the consideration being recognized once all performance obligations are satisfied. The timing and pattern of revenue recognition as it relates to ancillary revenues and guest parking revenues have not changed from those under ASC 605. Sale of real estate has been accounted for under ASC 610, Other Income , since the Company adopted this standard on January 1, 2018. This standard requires the Company to apply certain recognition and measurement principles in ASC 606 when it derecognizes nonfinancial assets and in substance nonfinancial assets, and the counterparty is not a customer. This is the case for the Company's sales of real estate, and therefore, 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 by the seller with the sold property, 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 of 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 (the “FASB”) in the form of Accounting Standards Update (“ASU”). The following ASUs were adopted by the Company in 2018: Standard Description Effect on the Financial Statements or Other Significant Matters ASU 2018-04, Investments—Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273 (SEC Update) ASU 2018-03, Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ASU 2016-01, Financial Instruments— Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities The guidance no longer allows the use of cost method of accounting for equity instruments that do not have a readily determinable fair value and Companies are now required to measure equity investments at fair value through net income. Companies are permitted to elect a measurement alternative that allows for measuring equity instruments at cost, less any impairment, plus or minus changes resulting from observable price changes, adjusted as of the date that an observable transaction takes place, rather than report date. For equity investments that do not have a readily determinable fair value, this guidance is adopted prospectively for all investments that exist as of the date of adoption. The guidance allows entities to use a prospective transition approach only for securities they elect to measure using the measurement alternative. The Company adopted this guidance during Q1 2018 using the prospective approach. The Company has elected to measure our equity instruments using the measurement alternative. Please see Note 12 for details. ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Therefore, a cumulative effect adjustment related to elimination of ineffectiveness measurement is required to be recorded to the opening balance of retained earnings as of the beginning of the fiscal year of adoption for cash flow hedge. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. This guidance must be applied using a modified retrospective approach. The Company adopted this guidance during Q1 2018 using the modified retrospective approach. As a result of the adoption, the concept of ineffectiveness from an accounting perspective is eliminated. Subsequent changes in fair value for a hedging instrument that has been designated and qualifies as a cash flow hedge will be recognized as a component in other comprehensive income. Additionally, the Company eliminated any previously recorded ineffectiveness with a cumulative effect adjustment. Please see Note 9 for details. ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting The guidance clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. This guidance must be applied prospectively. The Company adopted this guidance during Q1 2018 on a prospective basis. The adoption did not have an impact on the Consolidated Financial Statements. Standard Description Effect on the Financial Statements or Other Significant Matters ASU 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets The guidance updates the definition of an in substance nonfinancial asset and clarifies the scope of ASC 610-20 on the sale or transfer of nonfinancial assets to noncustomers, including partial sales. It also clarifies the derecognition guidance for nonfinancial assets to conform with the new revenue recognition standard. Either a full or modified retrospective approach can be applied. The Company adopted this guidance during Q1 2018 using the modified retrospective approach. The Company has not had variable consideration in our sale of real estate, or partial sales of nonfinancial assets or contribution of a nonfinancial asset to form a joint venture with retained noncontrolling interest, therefore the guidance does not currently impact the Company. ASU 2014-09, Revenue from Contracts with Customers amended by ASU 2016-08, Revenue from Contracts with Customers—Principal versus Agent Considerations (Reporting Revenue Gross versus Net) Issued on May 28, 2014, ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenues arising from contracts with customers and specifically notes that lease contracts with customers are a scope exception. Issued on March 17, 2016, ASU 2016-08 clarifies certain aspects of the principal-versus-agent guidance in its new revenue recognition standard related to the determination of whether an entity is a principal-versus-agent and the determination of the nature of each specified good or service. The guidance provides for practical expedients associated with the determination of whether a significant financing component exists and the expedient for recording an immediate expense for certain incremental costs of obtaining a contract with a customer. The Company adopted this guidance during Q1 2018 using the modified retrospective approach and is using the practical expedients associated with expensing incremental costs of obtaining a contract with a customer with terms of one year or less. The adoption of this ASU did not result in any changes with respect to the timing and pattern of revenue recognition. Please refer to the revenue recognition paragraph above for the additional disclosures. Update on ASC 842 implementation On February 25, 2016, the FASB issued ASU 2016-02, Leases , to amend the accounting guidance for leases and set out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a lease agreement (i.e., lessees and lessors). This ASU is effective for annual reporting periods (including interim periods) beginning after December 15, 2018. A modified retrospective approach must be applied for leases that exist or are entered into after January 1, 2017, the beginning of the earliest comparative period presented in the 2019 consolidated financial statements, with a cumulative adjustment to the opening balance of retained earnings (accumulated deficit) on January 1, 2017, and restatement of the amounts presented prior to January 1, 2019. On March 28, 2018, the FASB agreed to issue an amendment to ASU 842 that would provide an entity the optional transition method to initially account for the impact of the adoption with a cumulative adjustment to retained earnings (accumulated deficit) on the effective date of the ASU, January 1, 2019, rather than January 1, 2017, which would eliminate the need to restate amounts presented prior to January 1, 2019. This guidance requires all lessees to record a lease liability at lease inception, with a corresponding right-of-use asset, except for short-term leases. Lessor accounting will not be fundamentally changed. ASC 842 provides practical expedients that allow entities to not (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. The Company plans to adopt the standard on January 1, 2019 and expects to elect the use of practical expedients. If the proposed amendment to ASU 842 is adopted, the Company would elect the transition method for adoption as described above. Lessor Accounting The Company recognized rental revenues and tenant recoveries of $161.7 million and $158.3 million for the three months ended March 31, 2018 and March 31, 2017 . This ASU requires companies to identify lease and non-lease components of a lease agreement. Lease components relate to the right to use the leased asset and non-lease components relate to payments for goods or services that are transferred separately from the right to use the underlying asset. Total lease consideration is allocated to lease and non-lease components on a relative standalone basis. The recognition of revenues related to lease components will be governed by ASC 842 while revenue related to non-lease components will be subject to ASC 606. Under current accounting standards, the Company recognizes rental revenue from tenants on a straight-line basis over the lease term when collectability is reasonably assured and the tenant has taken possession or controls the physical use of the leased asset. 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, have discretion in selecting the supplier and bear the associated credit risk. In the March 28, 2018 FASB meeting, the FASB agreed to issue an amendment to ASC 842 which would allow lessors to elect, as a practical expedient, not to allocate the total consideration to lease and non-lease components based on their relative standalone selling prices. Once the amendment is adopted, this practical expedient will allow lessors 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 and, the combined single lease component would be classified as an operating lease. The Company has not completed its analysis of this ASU. Once the amendments discussed during the March 28, 2018 FASB meeting are issued, adopted and elected, tenant recoveries that qualify as non-lease components will be combined under a single lease component presentation. The ASU also requires lessors to capitalize only those costs that are defined as initial direct costs. Under the current accounting standards, the Company capitalizes initial direct and indirect leasing costs. During the three months ended March 31, 2018 and March 31, 2017 , the Company capitalized $1.8 million and $1.4 million of indirect leasing costs, respectively. Under this new ASU, these costs will be expensed as incurred. Lessee Accounting As of March 31, 2018 , the future undiscounted minimum lease payments under the Company’s ground leases totaled $449.3 million . This guidance requires lessees to record a lease liability at lease inception, with a corresponding right-of-use asset, except for short-term leases. The Company continues to evaluate the amount of right-of-use asset and lease liability that will ultimately be recorded with respect to its ground lease agreements, where it is the lessee. 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 2017 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 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 The amendments in this update permit an entity to elect an optional transition practical expedient to not evaluate under Topic 842 land easements that exist or expired before the entity’s adoption of Topic 842 and that were not previously accounted for as leases under Topic 840. An entity that elects this practical expedient should apply the practical expedient consistently to all of its existing or expired land easements that were not previously accounted for as leases under Topic 840. Once an entity adopts Topic 842, it should apply that Topic prospectively to all new (or modified) land easements to determine whether the arrangement should be accounted for as a lease. The effective date and transition requirements are the same as that in Update 2016-02 (Effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years.) The Company is currently evaluating the impact of this update.

Schedule of recently issued accounting pronouncements	The following ASUs were adopted by the Company in 2018: Standard Description Effect on the Financial Statements or Other Significant Matters ASU 2018-04, Investments—Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273 (SEC Update) ASU 2018-03, Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ASU 2016-01, Financial Instruments— Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities The guidance no longer allows the use of cost method of accounting for equity instruments that do not have a readily determinable fair value and Companies are now required to measure equity investments at fair value through net income. Companies are permitted to elect a measurement alternative that allows for measuring equity instruments at cost, less any impairment, plus or minus changes resulting from observable price changes, adjusted as of the date that an observable transaction takes place, rather than report date. For equity investments that do not have a readily determinable fair value, this guidance is adopted prospectively for all investments that exist as of the date of adoption. The guidance allows entities to use a prospective transition approach only for securities they elect to measure using the measurement alternative. The Company adopted this guidance during Q1 2018 using the prospective approach. The Company has elected to measure our equity instruments using the measurement alternative. Please see Note 12 for details. ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. Therefore, a cumulative effect adjustment related to elimination of ineffectiveness measurement is required to be recorded to the opening balance of retained earnings as of the beginning of the fiscal year of adoption for cash flow hedge. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. This guidance must be applied using a modified retrospective approach. The Company adopted this guidance during Q1 2018 using the modified retrospective approach. As a result of the adoption, the concept of ineffectiveness from an accounting perspective is eliminated. Subsequent changes in fair value for a hedging instrument that has been designated and qualifies as a cash flow hedge will be recognized as a component in other comprehensive income. Additionally, the Company eliminated any previously recorded ineffectiveness with a cumulative effect adjustment. Please see Note 9 for details. ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting The guidance clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. This guidance must be applied prospectively. The Company adopted this guidance during Q1 2018 on a prospective basis. The adoption did not have an impact on the Consolidated Financial Statements. Standard Description Effect on the Financial Statements or Other Significant Matters ASU 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets The guidance updates the definition of an in substance nonfinancial asset and clarifies the scope of ASC 610-20 on the sale or transfer of nonfinancial assets to noncustomers, including partial sales. It also clarifies the derecognition guidance for nonfinancial assets to conform with the new revenue recognition standard. Either a full or modified retrospective approach can be applied. The Company adopted this guidance during Q1 2018 using the modified retrospective approach. The Company has not had variable consideration in our sale of real estate, or partial sales of nonfinancial assets or contribution of a nonfinancial asset to form a joint venture with retained noncontrolling interest, therefore the guidance does not currently impact the Company. ASU 2014-09, Revenue from Contracts with Customers amended by ASU 2016-08, Revenue from Contracts with Customers—Principal versus Agent Considerations (Reporting Revenue Gross versus Net) Issued on May 28, 2014, ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenues arising from contracts with customers and specifically notes that lease contracts with customers are a scope exception. Issued on March 17, 2016, ASU 2016-08 clarifies certain aspects of the principal-versus-agent guidance in its new revenue recognition standard related to the determination of whether an entity is a principal-versus-agent and the determination of the nature of each specified good or service. The guidance provides for practical expedients associated with the determination of whether a significant financing component exists and the expedient for recording an immediate expense for certain incremental costs of obtaining a contract with a customer. The Company adopted this guidance during Q1 2018 using the modified retrospective approach and is using the practical expedients associated with expensing incremental costs of obtaining a contract with a customer with terms of one year or less. The adoption of this ASU did not result in any changes with respect to the timing and pattern of revenue recognition. Please refer to the revenue recognition paragraph above for the additional disclosures.
Schedule of new accounting pronouncements	The following table lists the recently issued ASUs that have not been disclosed in the Company ’s 2017 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 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 The amendments in this update permit an entity to elect an optional transition practical expedient to not evaluate under Topic 842 land easements that exist or expired before the entity’s adoption of Topic 842 and that were not previously accounted for as leases under Topic 840. An entity that elects this practical expedient should apply the practical expedient consistently to all of its existing or expired land easements that were not previously accounted for as leases under Topic 840. Once an entity adopts Topic 842, it should apply that Topic prospectively to all new (or modified) land easements to determine whether the arrangement should be accounted for as a lease. The effective date and transition requirements are the same as that in Update 2016-02 (Effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years.) The Company is currently evaluating the impact of this update.
