Organization	'
	Organization
	Hudson Pacific Properties, Inc. (which is referred to in these financial statements as the “Company,” “we,” “us,” or “our”) is a Maryland corporation formed on November 9, 2009 that did not have any meaningful operating activity until the consummation of our initial public offering and the related acquisition of our predecessor and certain other entities on June 29, 2010 (“IPO”).
	Since the completion of the IPO, we have been a fully integrated, self-administered, and self-managed real estate investment trust (“REIT”). Through our controlling interest in Hudson Pacific Properties, L.P. (our “Operating Partnership”) and its subsidiaries, we own, manage, lease, acquire and develop real estate, consisting primarily of office and media and entertainment properties. As of September 30, 2014, we owned a portfolio of 25 office properties and two media and entertainment properties. These properties are located in California and Washington. The results of operations for properties acquired after our IPO are included in our consolidated statements of operations from the date of each such acquisition.

Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements of the Company are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The effect of all significant intercompany balances and transactions has been eliminated.

The accompanying unaudited interim financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States may have been condensed or omitted pursuant to SEC rules and regulations, although we believe that the disclosures are adequate to make their presentation not misleading. The accompanying unaudited financial statements include, in our opinion, all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial information set forth therein. 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, 2014. The interim financial statements should be read in conjunction with the consolidated financial statements in our 2013 Annual Report on Form 10-K and the notes thereto. Any reference to the number of properties and square footage are unaudited and outside the scope of our independent registered public accounting firm’s review of our financial statements in accordance with the standards of the United States Public Company Accounting Oversight Board.

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.

Investment in Real Estate Properties

The properties are carried at cost less accumulated depreciation and amortization. The Company assigns the cost of an acquisition, including the assumption of liabilities, to the acquired tangible assets and identifiable intangible assets and liabilities based on their estimated fair values in accordance with GAAP. The Company assesses fair value based on estimated cash flow projections that utilize discount and/or capitalization rates and available market information. 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 was vacant.

Acquisition-related expenses associated with acquisition of operating properties are expensed in the period incurred.

The Company records acquired above- and below- market leases at fair value using 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 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 capitalizes direct construction and development costs, including predevelopment costs, interest, property taxes, insurance and other costs directly related and essential to the acquisition, development or construction of a real estate project. Indirect development costs, including salaries and benefits, office rent, and associated costs for those individuals directly responsible for and who spend their time on development activities are also capitalized and allocated to the projects to which they relate. Capitalized personnel costs for the three and nine months ended September 30, 2014 were approximately $0.8 million and $2.1 million, respectively, and $0.5 million and $1.5 million for the three and nine months ended September 30, 2013, respectively. Interest is capitalized on the construction in progress at a rate equal to the Company’s weighted average cost of debt. Capitalized interest for the three and nine months ended September 30, 2014 was approximately $1.9 million and $5.2 million, respectively, and $1.1 million and $2.8 million for the three and nine months ended September 30, 2013, respectively. Construction and development costs are capitalized while substantial activities are ongoing to prepare an asset for its intended use. The Company considers a construction project as substantially complete and held available for occupancy upon the completion of tenant improvements but no later than one year after cessation of major construction activity. Costs incurred after a project is substantially complete and ready for its intended use, or after development activities have ceased, are expensed as they are incurred. Costs previously capitalized related to abandoned acquisitions or developments are charged to earnings. Expenditures for repairs and maintenance are expensed as they are incurred.

The Company computes depreciation using the straight-line method over the estimated useful lives of 39 years for building and improvements, 15 years for land improvements, 5 to 7 years for furniture and fixtures and equipment, and over the shorter of asset life or life of the lease for tenant improvements. Above- and below-market lease intangibles are amortized to revenue over the remaining non-cancellable lease terms and bargain renewal periods, if applicable. Other in-place lease intangibles are amortized to expense over the remaining non-cancellable lease term. Depreciation is discontinued when a property is identified as held for sale.

Impairment of Long-Lived Assets

The Company assesses the carrying value of real estate assets and related intangibles whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable in accordance with GAAP. Impairment losses are recorded on real estate assets held for investment when indicators of impairment are present and the future undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. The Company recognizes impairment losses to the extent the carrying amount exceeds the fair value of the properties. Properties held for sale are recorded at the lower of cost or estimated fair value less cost to sell. There were no properties held for sale at September 30, 2014 and December 31, 2013. The Company recorded $5.6 million of impairment charges related to a property held for sale during the nine months ended September 30, 2013 with no comparable charge for the nine months ended September 30, 2014.

Goodwill

Goodwill represents the excess of acquisition cost over the fair value of net tangible and identifiable intangible assets acquired and liabilities assumed in business combinations. Our goodwill balance as of September 30, 2014 was $8.8 million. We do not amortize this asset but instead analyze it on an annual basis for impairment. No impairment indicators have been noted during the three and nine months ended September 30, 2014 and 2013.

Cash and Cash Equivalents

Cash and cash equivalents are defined as cash on hand and in banks, plus all short-term investments with a maturity of three months or less when purchased.

The Company maintains some of its cash in bank deposit accounts that, at times, may exceed the federally insured limit. No losses have been experienced related to such accounts.

Restricted Cash

Restricted cash consists of amounts held by lenders to provide for future real estate taxes and insurance expenditures, repairs and capital improvements reserves, general and other reserves and security deposits.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable consist of amounts due for monthly rents and other charges. The Company maintains an allowance for doubtful accounts for estimated losses resulting from tenant defaults or the inability of tenants to make contractual rent and tenant recovery payments. The Company monitors the liquidity and creditworthiness of its tenants and operators on an ongoing basis. This evaluation considers industry and economic conditions, property performance, credit enhancements and other factors. For straight-line rent amounts, the Company’s assessment is based on amounts estimated to be recoverable over the term of the lease. At September 30, 2014 and December 31, 2013, the Company had reserved $0.5 million and $0.3 million, respectively, of straight-line receivables. The Company evaluates the collectability of accounts receivable based on a combination of factors. The allowance for doubtful accounts is based on specific identification of uncollectible accounts and the Company’s historical collection experience. The Company recognizes an allowance for doubtful accounts based on the length of time the receivables are past due, the current business environment and the Company’s historical experience. Historical experience has been within management’s expectations. The Company recognized $(0.3) million and $0.2 million of bad debt (recovery) expense for the nine months ended September 30, 2014 and 2013, respectively.

Revenue Recognition

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. If the lease provides for tenant improvements, the Company determines whether the tenant improvements, for accounting purposes, are owned by the tenant or the Company. When the Company is the owner of the tenant improvements, the tenant is not considered to have taken physical possession or have control of the physical use of the leased asset until the tenant improvements are substantially completed. When the tenant is the owner of the tenant improvements, any tenant improvement allowance that is funded is treated as a lease incentive and amortized as a reduction of revenue over the lease term. Tenant improvement ownership is determined based on various factors including, but not limited to:

•

whether the lease stipulates how and on what a tenant improvement allowance may be spent;

•

whether the tenant or landlord retains legal title to the improvements at the end of the lease term;

•

whether the tenant improvements are unique to the tenant or general-purpose in nature; and

•

whether the tenant improvements are expected to have any residual value at the end of the lease.

Certain leases provide for additional rents contingent upon a percentage of the tenant’s revenue in excess of specified base amounts or other thresholds. Such revenue is recognized when actual results reported by the tenant, or estimates of tenant results, exceed the base amount or other thresholds. Such revenue is recognized only after the contingency has been removed (when the related thresholds are achieved), which may result in the recognition of rental revenue in periods subsequent to when such payments are received.

Other property-related revenue is revenue that is derived from the tenants’ use of lighting, equipment rental, parking, power, HVAC and telecommunications (phone and Internet). Other property-related revenue is recognized when these items are provided.

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.

The Company recognizes gains on sales of properties upon the closing of the transaction with the purchaser. Gains on properties sold are recognized using the full accrual method when (i) the collectability of the sales price is reasonably assured, (ii) the Company is not obligated to perform significant activities after the sale, (iii) the initial investment from the buyer is sufficient and (iv) other profit recognition criteria have been satisfied. Gains on sales of properties may be deferred in whole or in part until the requirements for gain recognition have been met.

Deferred Financing Costs

Deferred financing costs are amortized over the term of the respective loan.

Derivative Financial Instruments

The Company manages interest rate risk associated with borrowings by entering into interest rate derivative contracts. The Company recognizes all derivatives on the consolidated balance sheet at fair value. Derivatives that are not hedges are adjusted to fair value and the changes in fair value are reflected as income or expense. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings, or recognized in other comprehensive income, which is a component of equity. The ineffective portion of a derivative’s change in fair value is immediately recognized in earnings.

The Company held three interest rate contracts as of September 30, 2014 and December 31, 2013, respectively, all of which have been accounted for as cash flow hedges as more fully described in note 6 below.

Stock-Based Compensation

Accounting Standard Codification, (“ASC”), Topic 718, Compensation—Stock Compensation (“ASC 718”), requires us to recognize an expense for the fair value of equity-based compensation awards. Grants of stock options, restricted stock, restricted stock units and performance units under our equity incentive award plans are accounted for under ASC 718. Our compensation committee regularly considers the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our equity incentive award plans and programs.

Income Taxes

Our taxable income prior to the completion of our IPO is reportable by the members of the limited liability companies that comprise our predecessor. Our property-owning subsidiaries are limited liability companies and are treated as pass-through entities for 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.

We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) commencing with our initial taxable year. To qualify as a REIT, we are required to distribute at least 90% of our REIT taxable income to our stockholders and meet the various other requirements imposed by the Code relating to such matters as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we qualify for taxation as a REIT, we are generally not subject to corporate-level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. If we fail to qualify as a REIT in any taxable year, and are unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax.

We have elected, together with one of our subsidiaries, to treat such subsidiary as a taxable REIT subsidiary (“TRS”) for federal income tax purposes. Certain activities that we undertake must be conducted by a TRS, such as non-customary services for our tenants and holding assets that we cannot hold directly. A TRS is subject to federal and state income taxes.

The Company is subject to the statutory requirements of the states in which it conducts business.

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, 2014, the Company had not established a liability for uncertain tax positions.

Fair Value of Assets and Liabilities

Under GAAP, the Company is required to measure certain financial instruments at fair value on a recurring basis. In addition, the Company is required to measure other financial instruments and balances at fair value on a non-recurring basis (e.g., carrying value of impaired real estate and long-lived assets). Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. 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 requires inputs that are both significant to the fair value measurement and unobservable.

When available, the Company utilizes quoted market prices from an independent third-party source to determine fair value and classifies such items in Level 1 or Level 2. In instances where the market for a financial instrument is not active, regardless of the availability of a nonbinding quoted market price, observable inputs might not be relevant and could require the Company to make a significant adjustment to derive a fair value measurement. Additionally, in an inactive market, a market price quoted from an independent third party may rely more on models with inputs based on information available only to that independent third party. When the Company determines the market for a financial instrument owned by the Company to be illiquid or when market transactions for similar instruments do not appear orderly, the Company uses several valuation sources (including internal valuations, discounted cash flow analysis and quoted market prices) and establishes a fair value by assigning weights to the various valuation sources.

Changes in assumptions or estimation methodologies can have a material effect on these estimated fair values. In this regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in an immediate settlement of the instrument.

The Company considers the following factors to be indicators of an inactive market: (i) there are few recent transactions, (ii) price quotations are not based on current information, (iii) price quotations vary substantially either over time or among market makers (for example, some brokered markets), (iv) indexes that previously were highly correlated with the fair values of the asset or liability are demonstrably uncorrelated with recent indications of fair value for that asset or liability, (v) there is a significant increase in implied liquidity risk premiums, yields, or performance indicators (such as delinquency rates or loss severities) for observed transactions or quoted prices when compared with the Company’s estimate of expected cash flows, considering all available market data about credit and other nonperformance risk for the asset or liability, (vi) there is a wide bid-ask spread or significant increase in the bid-ask spread, (vii) there is a significant decline or absence of a market for new issuances (that is, a primary market) for the asset or liability or similar assets or liabilities, and (viii) little information is released publicly (for example, a principal-to-principal market).

The Company considers the following factors to be indicators of non-orderly transactions: (i) there was not adequate exposure to the market for a period before the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities under current market conditions, (ii) there was a usual and customary marketing period, but the seller marketed the asset or liability to a single market participant, (iii) the seller is in or near bankruptcy or receivership (that is, distressed), or the seller was required to sell to meet regulatory or legal requirements (that is, forced), and (iv) the transaction price is an outlier when compared with other recent transactions for the same or similar assets or liabilities.

The Company’s interest rate contract agreements are classified as Level 2 and their fair value is derived from estimated values obtained from observable market data for similar instruments.

As of September 30, 2014, the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk:

Recently Issued Accounting Literature

Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of an Accounting Standards Update (“ASU”). We consider the applicability and impact of all ASUs. Recently issued ASUs not listed below are not expected to have a material impact on our consolidated financial position and results of operations, because either the ASU is not applicable or the impact is expected to be immaterial.

On June 19, 2014, the FASB issued their final standard to amend the accounting guidance for stock compensation tied to performance targets (ASU No. 2014-12). The issue is the result of a consensus of the FASB Emerging Issues Task Force (Issue No. 13-D). The standard requires that a performance target that could be achieved after the requisite service period be treated as a performance condition, and as a result, this type of performance condition may delay expense recognition until achievement of the performance target is probable. The ASU is effective for all entities for reporting periods (including interim periods) beginning after December 15, 2015, and early adoption is permitted. The Company will adopt the guidance effective January 1, 2016 and the guidance is not expected to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

On May 28, 2014, the FASB issued their final standard on revenue from contracts with customers. The guidance specifically notes that lease contracts with customers are a scope exception. The standard (ASU No. 2014-09) outlines a single comprehensive model for entities to use in accounting for revenues arising from contracts with customers. The ASU is effective for annual reporting periods (including interim periods) beginning after December 15, 2016, and early adoption is not permitted. The Company will adopt the guidance effective January 1, 2017 and is currently assessing the impact on our consolidated financial statements and notes to our consolidated financial statements.

On April 10, 2014, the FASB issued final guidance to change the criteria for reporting discontinued operations while enhancing disclosures in this area (ASU No. 2014-08). Under the new guidance, only disposals representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held for sale should be reported as discontinued operations. The guidance also expands the disclosure requirements for discontinued operations and adds new disclosures for individually significant dispositions that do not qualify as discontinued operations. The guidance will be applied prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The guidance is effective for annual financial statements with fiscal years beginning on or after December 15, 2014 with early adoption permitted for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. As of January 1, 2014, we have early adopted the amended guidance and the result did not have a meaningful impact on our consolidated financial position or results of operations.

	Senior Unsecured Credit Facility
	On September 23, 2014, we amended and restated our $250.0 million unsecured revolving credit facility to increase the unsecured revolving credit facility to $300.0 million, extend the term of that facility to September 23, 2018, and add a five-year, $150.0 million unsecured term loan facility with a group of lenders for which Wells Fargo Bank, N.A. acts as administrative agent, and Wells Fargo Securities, LLC and Merrill Lynch, Pierce, Fenner and Smith Incorporated act as joint lead arrangers, and Bank of America, N.A. and Barclays Bank PLC, act as joint syndication agents, and Keybank, N.A., acts as documentation agent.
	The $150.0 million unsecured term loan facility was fully drawn by the Company on the closing date to repay a $95.0 million loan secured by the Company’s 505 First Street and 83 King properties, with the remaining $55.0 million used to repay amounts outstanding under the Company’s prior unsecured revolving facility.
	Our Operating Partnership continues to be the borrower under the new facility and the Company and all subsidiaries that own unencumbered properties will continue to provide guaranties unless the Company obtains and maintains a credit rating of at least BBB- from S&P or Baa3 from Moody’s, in which case such guaranties are not required except under limited circumstances.  Subject to the satisfaction of certain conditions and lender commitments, the Company may increase the availability of either or both of the revolving credit facility or term loan facility so long as the aggregate commitments under both facilities do not exceed $700.0 million.
	Under the revolving credit facility, the Company may elect to pay interest at a rate equal to either LIBOR plus 115 to 155 basis points per annum or a specified base rate plus 15 to 55 basis points per annum, depending on the Company’s leverage ratio. Under the term loan facility, the Company may elect to pay interest at a rate equal to either LIBOR plus 130 to 190 basis points per annum or a specified base rate plus 30 to 90 basis points per annum, again depending on the Company’s leverage ratio. If the Company obtains a credit rating for its senior unsecured long term indebtedness, it may make an irrevocable election to change the interest rate for the revolving credit facility to a rate equal to either LIBOR plus 87.5 to 165 basis points per annum or the specified base rate plus 0 to 65 basis points per annum, and for the term loan facility equal to either LIBOR plus 90 to 190 basis points per annum or the specified base rate plus 0 to 90 basis points per annum, in each case depending on the credit rating.
	The revolving credit facility is subject to a facility fee in an amount equal to the Company’s revolving credit commitments (whether or not utilized) multiplied by a rate per annum equal to 20 to 35 basis points, depending on the Company’s leverage ratio, or, if the Company makes the credit rating election, in an amount equal to the aggregate amount of its revolving credit commitments multiplied by a rate per annum equal to 12.5 to 30 basis points, depending upon the credit rating. Unused amounts of the facility are no longer subject to a separate fee.
	The Company’s ability to borrow under the facility remains subject to ongoing compliance with a number of customary restrictive covenants. In addition to these covenants, the facility also includes certain limitations on dividend payouts and distributions, limits on certain types of investments outside of the Company’s primary business, and other customary affirmative and negative covenants.
	As of September 30, 2014, we were in compliance with our facility’s financial covenants. As of September 30, 2014, we had $300.0 million of total capacity under our unsecured revolving credit facility, of which $95.0 million had been drawn.
	The following table sets forth information as of September 30, 2014 with respect to our outstanding indebtedness.

	Non-controlling Interests
	Common units in the Operating Partnership
	Common units in the operating partnership consisted of 2,382,563 common units of partnership interests, or common units, not owned by us. Common units and shares of our common stock have essentially the same economic characteristics, as they share equally in the total net income or loss distributions of our operating partnership. Investors who own common units have the right to cause our operating partnership to redeem any or all of their common units for cash equal to the then-current market value of one share of common stock or, at our election, issue shares of our common stock in exchange for common units on a one-for-one basis.
	Non-controlling interest—members in consolidated entities
	Non-controlling interest—members in consolidated entities refers to our joint venture partner, Media Center Partners, LLC, a California limited liability company (“MCP”), with which we have entered into a joint venture, Hudson MC Partners, LLC, a Delaware limited liability company (the “Pinnacle JV”), to acquire The Pinnacle, a two-building (Pinnacle I and Pinnacle II), 625,640 square-foot office property located in Burbank, California. As of September 30, 2014, we owned a 65.0% interest in the Pinnacle JV, which owns the 625,640 square-foot project known as The Pinnacle. As of December 31, 2012 and until the acquisition by the Pinnacle JV of the 231,864 square-foot Pinnacle II building on June 14, 2013, we owned a 98.25% interest in the Pinnacle JV, which owns the 393,776 square-foot Pinnacle I building.
	6.25% series A cumulative redeemable preferred units of the Operating Partnership
	6.25% series A cumulative redeemable preferred units of the Operating Partnership are 407,066 series A preferred units of partnership interest in our operating partnership, or series A preferred units, that are not owned by us. 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 our option, exchangeable for registered shares of common stock, after June 29, 2013. In October 2013, one of our series A preferred unit holders required us to redeem 80,000 series A preferred units. We elected to redeem these units for cash equal to the liquidation preference of $25.00 per unit. As a result of this redemption, our outstanding series A preferred units decreased from 499,014 units outstanding to 419,014 units outstanding. In March 2014, one of our series A preferred unit holders required us to redeem 11,948 series A preferred units. We elected to redeem these units for cash equal to the liquidation preference of $25.00 per unit. As a result of this redemption, our outstanding series A preferred units decreased from 419,014 units outstanding to the current 407,066 units outstanding as of September 30, 2014. 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 our June 23, 2010 Prospectus.
	8.375% Series B cumulative redeemable preferred stock
	8.375% series B cumulative redeemable preferred stock are 5,800,000 shares of 8.375% preferred stock, with a liquidation preference of $25.00 per share, $0.01 par value per share. In December 2010, we completed the public offering of 3,500,000 share of our series B preferred stock (including 300,000 shares of series B preferred stock issued and sold pursuant to the exercise of the underwriters’ option to purchase additional shares in part). Total proceeds from the offering, after deducting underwriting discount, were approximately $83.9 million (before transaction costs). On January 23, 2012, we completed the public offering of 2,300,000 of our series B cumulative preferred stock (including 300,000 shares of series B preferred stock issued and sold pursuant to the exercise of the underwriters’ option to purchase additional shares in full). Total proceeds from the offering, after deducting underwriting discount, were approximately $57.5 million (before transaction costs).
	Dividends on our series B preferred stock are cumulative from the date of original issue and payable quarterly on or about the last calendar day of each March, June, September and December, at the rate of 8.375% per annum of its $25.00 per share liquidation preference (equivalent to $2.0938 per share per annum). If, following a change of control of the Company, either our series B preferred stock (or any preferred stock of the surviving entity that is issued in exchange for our series B preferred stock) or the common stock of the surviving entity, as applicable, is not listed on the New York Stock Exchange, or NYSE, or quoted on the NASDAQ Stock Market, or NASDAQ (or listed or quoted on a successor exchange or quotation system), holders of our series B preferred stock will be entitled to receive cumulative cash dividends from, and including, the first date on which both the change of control occurred and either our series B preferred stock (or any preferred stock of the surviving entity that is issued in exchange for our series B preferred stock) or the common stock of the surviving entity, as applicable, is not so listed or quoted, at the increased rate of 12.375% per annum per share of the liquidation preference of our series B preferred stock (equivalent to $3.09375 per annum per share) for as long as either our series B preferred stock (or any preferred stock of the surviving entity that is issued in exchange for our series B preferred stock) or the common stock of the surviving entity, as applicable, is not so listed or quoted. Except in instances relating to preservation of our qualification as a REIT or in connection with a change of control of the Company, our series B preferred stock is not redeemable prior to December 10, 2015. On and after December 10, 2015, we may redeem our series B preferred stock in whole, at any time, or in part, from time to time, for cash at a redemption price of $25.00 per share, plus any accrued and unpaid dividends to, but not including, the date of redemption. If at any time following a change of control either our series B preferred stock (or any preferred stock of the surviving entity that is issued in exchange for our series B preferred stock) or the common stock of the surviving entity, as applicable, is not listed on the NYSE or quoted on NASDAQ (or listed or quoted on a successor exchange or quotation system), we will have the option to redeem our series B preferred stock, in whole but not in part, within 90 days after the first date on which both the change of control has occurred and either our series B preferred stock (or any preferred stock of the surviving entity that is issued in exchange for our series B preferred stock) or the common stock of the surviving entity, as applicable, is not so listed or quoted, for cash at $25.00 per share, plus accrued and unpaid dividends, if any, to, but not including, the redemption date. Our series B preferred stock has no maturity date and will remain outstanding indefinitely unless redeemed by us, and it is not subject to any sinking fund or mandatory redemption and is not convertible into any of our other securities. For a full description of the Series B cumulative redeemable preferred stock, please see “Description of our Preferred Stock” in our December 7, 2010 Prospectus.
	February 2013 Common Stock Offering
	On February 12, 2013, we completed the public offering of 8,000,000 shares of common stock and the exercise of the underwriters’ option to purchase an additional 1,200,000 shares of our common stock at the public offering price of $21.50 per share. Total proceeds from the public offering, after underwriters’ discount, were approximately $189.9 million (before transaction costs).
	January 2014 Common Stock Offering
	On January 28, 2014, we completed the public offering of 8,250,000 shares of common stock and the exercise of the underwriters’ option to purchase an additional 1,237,500 shares of our common stock at the public offering price of $21.50 per share. Total proceeds from the public offering, after underwriters’ discount, were approximately $195.8 million (before transaction costs).
	Dividends
	During the third quarter for 2014, we declared dividends on our common stock and non-controlling common partnership interests of $0.125 per share and unit. We also declared dividends on our series A preferred partnership interests of $0.3906 per unit. In addition, we declared dividends on our series B preferred shares of $0.5234 per share. The third quarter dividends were declared on September 8, 2014 to holders of record on September 20, 2014.
	Taxability of Dividends
	Earnings and profits, which determine the taxability of distributions to stockholders, may differ from income reported for financial reporting purposes because of the differences for federal income tax purposes in the treatment of loss on extinguishment of debt, revenue recognition, and compensation expense and in the basis of depreciable assets and estimated useful lives used to compute depreciation.
	Stock-Based Compensation
	The Board of Directors 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 our Non-Employee Director Compensation Program. The share-based awards are generally issued in the second quarter, and the individual share awards vest in equal annual installments over the applicable service vesting period, which is three years.
	In addition, the Board of Directors awards restricted shares to employees on an annual basis as part of the employees’ annual compensation. The share-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 three years.
	The following table summarizes the restricted share activity for the nine months ended September 30, 2014 and status of all unvested restricted share awards to our non-employee board members and employees at September 30, 2014:
	Non-vested Shares	Shares		Weighted-Average Grant-Date Fair Value

	We recognize the total compensation expense for time-vested shares on a straight-line basis over the vesting period based on the fair value of the award on the date of grant.
	Hudson Pacific Properties, Inc. Outperformance Programs
	In each of 2012, 2013 and 2014, the Compensation Committee of our Board of Directors adopted a Hudson Pacific Properties, Inc. Outperformance Program (individually, the “2012 OPP,” the “2013 OPP” and the “2014 OPP” and, together, the “OPPs”). Participants in the 2012 OPP, 2013 OPP and 2014 OPP may earn, in the aggregate, up to $10 million, $11 million and $12 million, respectively, of stock-settled awards based on our Total Shareholder Return, or TSR, for the three-year period beginning January 1 of the year in which the applicable OPP was adopted and ending December 31 of 2014, 2015 or 2016, respectively.
	Under each OPP, participants will be entitled to share in a performance pool with a value, subject to the applicable dollar-denominated cap described above, equal to the sum of: (i) 4% of the amount by which our TSR during the applicable performance period exceeds 9% simple annual TSR (the “absolute TSR component”), plus (ii) 4% of the amount by which our TSR during the applicable performance period exceeds that of the SNL Equity REIT Index (determined on a percentage basis that is then multiplied by the sum of (A) our market capitalization on that date, plus (B) the aggregate per share dividend over the applicable performance period through such date) (the “relative TSR component”), except that the relative TSR component will be reduced on a linear basis from 100% to zero percent for absolute TSR ranging from 7% to zero percent simple annual TSR over the applicable performance period. In addition, the relative TSR component may be a negative value equal to 4% of the amount by which we underperform the SNL Equity REIT Index by more than 3% per year during the applicable performance period (if any).
	With respect to the 2012 OPP, if we attain pro-rated TSR performance goals during 2012 and/or 2013 that yield hypothetical bonus pools of up to $2 million for 2012 performance and/or up to $4 million for combined 2012/2013 performance, stock awards issued under the final bonus pool at the end of the applicable performance period will cover a number of shares in the aggregate at least equal to the number of shares that would have been subject to stock awards issued at the end of 2012 or 2013 (whichever is greater) based on our TSR performance and common stock price for such prior years (subject to reduction to comply with the $10 million bonus pool limitation). Similarly, with respect to the 2013 OPP , if we attain pro-rated TSR performance goals during 2013 and/or 2014 that yield hypothetical bonus pools of up to $2 million for 2013 performance and/or up to $4 million for combined 2013/2014 performance, stock awards issued under the final bonus pool at the end of the applicable performance period will cover a number of shares in the aggregate at least equal to the number of shares that would have been subject to stock awards issued at the end of 2013 or 2014 (whichever is greater) based on our TSR performance and common stock price for such prior years (subject to reduction to comply with the $11 million bonus pool limitation).
	At the end of the applicable three-year performance period, participants who remain employed with us will be paid their percentage interest in the bonus pool as stock awards based on the value of our common stock at the end of the performance period. Half of each such participant’s bonus pool interest will be paid in fully vested shares of our common stock and the other half will be paid in RSUs that vest in equal annual installments over the two years immediately following the applicable performance period (based on continued employment) and which carry tandem dividend equivalent rights. However, if the applicable performance period is terminated in connection with a change in control, OPP awards will be paid entirely in fully vested shares of our common stock immediately prior to the change in control. In addition to these share/RSU payments, each OPP award entitles its holder to a cash payment equal to the aggregate dividends that would have been paid during the applicable performance period on the total number of shares and RSUs ultimately issued or granted in respect of such OPP award, had such shares and RSUs been outstanding throughout the performance period.
	If a participant’s employment is terminated without “cause,” for “good reason” or due to the participant’s death or disability during the applicable performance period (referred to as qualifying terminations), the participant will be paid his or her OPP award at the end of the performance period entirely in fully vested shares (except for the performance period dividend equivalent, which will be paid in cash at the end of the performance period). Any such payment will be pro-rated in the case of a termination without “cause” or for “good reason” by reference to the participant’s period of employment during the applicable performance period. If we experience a change in control or a participant experiences a qualifying termination of employment, in either case, after the end of the applicable performance period, any unvested RSUs that remain outstanding will accelerate and vest in full upon such event.
	The cost of the 2012 OPP, the 2013 OPP and the 2014 OPP (approximately $3.49 million, $4.14 million and $3.21 million, respectively, subject to a forfeiture adjustment equal to 6%, 6% and 10%, respectively, of the total cost) will be amortized through the final vesting period under a graded vesting expense recognition schedule.
	The 2012 OPP, 2013 OPP and 2014 OPP were valued, in accordance with ASC 718, at an aggregate of approximately $3.49 million, $4.14 million and $3.21 million, respectively, utilizing a Monte Carlo simulation to estimate the probability of the performance vesting conditions being satisfied. The Monte Carlo simulation used a statistical formula underlying the Black-Scholes and binomial formulas and such simulation was run 100,000 times. For each simulation, the payoff is calculated at the settlement date, which is then discounted to the award date at a risk-free interest rate. The average of the values over all simulations is the expected value of the unit on the award date. Assumptions used in the valuations included (1) factors associated with the underlying performance of the Company’s stock price and total shareholder return over the term of the performance awards including total stock return volatility and risk-free interest and (2) factors associated with the relative performance of the Company’s stock price and total shareholder return when compared to the SNL Equity REIT Index. The valuation was performed in a risk-neutral framework, so no assumption was made with respect to an equity risk premium. The fair value of the OPP awards is based on the sum of: (1) the present value of the expected payoff to the awards on the measurement date, if the TSR over the applicable measurement period exceeds performance hurdles of the absolute and the relative TSR components; and (2) the present value of the distributions payable on the awards. The ultimate reward realized on account of the OPP awards by the holders of the awards is contingent on the TSR achieved on the measurement date, both in absolute terms and relative to the TSR of the SNL Equity REIT Index. The per unit fair value of each 2012 OPP award, 2013 OPP award and 2014 OPP award was estimated on the date of grant using the following assumptions in the Monte Carlo valuation: expected price volatility for the Company and the SNL Equity REIT index of 36% and 35%, 33% and 25%, and 28% and 26%, respectively; a risk-free rate of 0.40%, 0.38% and 0.77%, respectively; and total dividend payments over the measurement period of $1.62, $1.50 and $1.50, respectively, per share.
	For the nine months ended September 30, 2014 and 2013, $5.3 million and $5.2 million, respectively, of non-cash compensation expense for all stock compensation was recognized as additional paid-in capital, of which $5.0 million and $5.0 million, respectively, was included in general and administrative expenses, with the remaining $0.3 million and $0.2 million, respectively, of stock compensation capitalized to tenant improvement and deferred leasing costs and lease intangibles, net.

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, our 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, 2014, the risk of material loss from such legal actions impacting the Company’s financial condition or results from operations has been assessed as remote.
	Concentrations
	As of September 30, 2014, the majority of the Company’s properties were located in California, which exposes the Company to greater economic risks than if it owned a more geographically dispersed portfolio. Further, for the nine months ended September 30, 2014 and 2013, approximately 16% and 21%, respectively, of the Company’s revenues were derived from tenants in the media and entertainment industry, which makes the Company susceptible to demand for rental space in such industry. Consequently, the Company is subject to the risks associated with an investment in real estate with a concentration of tenants in that industry.

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) media and entertainment properties. The Company evaluates performance based upon property net operating income from continuing operations (“NOI”) of the combined properties in each segment. NOI is not a measure of operating results or cash flows from operating activities as measured by GAAP, is not indicative of cash available to fund cash needs and should not be considered an alternative to cash flows as a measure of liquidity. All companies may not calculate NOI in the same manner. The Company considers NOI to be an appropriate supplemental financial measure to net income because it helps both investors and management to understand the core operations of the Company’s properties. The Company defines NOI as operating revenues (including rental revenues, other property-related revenue, tenant recoveries and other operating revenues), less property-level operating expenses (which includes external management fees and property-level general and administrative expenses). NOI excludes corporate general and administrative expenses, depreciation and amortization, impairments, gain/loss on sale of real estate, interest expense, acquisition-related expenses and other non-operating items.
	Summary information for the reportable segments for the nine months ended September 30, 2014 is as follows:
		Office Properties			Media and  Entertainment			Total
					Properties
	Revenue	$	155,693		$	30,187		$	185,880
	Operating expenses	58,469			19,244			77,713
	Net operating income	$	97,224		$	10,943		$	108,167
	Summary information for the reportable segments for the nine months ended September 30, 2013 is as follows:
		Office Properties			Media and  Entertainment			Total

	Revenue	$	117,754		$	30,387		$	148,141
	Operating expenses	44,191			18,133			62,324
	Net operating income	$	73,563		$	12,254		$	85,817
	The following is reconciliation from NOI to reported net income, the most direct comparable financial measure calculated and presented in accordance with GAAP:
		September 30, 2014			September 30, 2013
	Net operating income	$	108,167		$	85,817
	General and administrative	(19,157		)	(15,195		)

	Acquisition-related expenses	(319		)	(992		)
	Other expense	43			(41		)
	Income from continuing operations	$	17,263		$	(1,891	)
	There were no inter-segment sales or transfers during either of the nine months ended September 30, 2014 and 2013.
	Asset information by segment is not reported because we do not use this measure to assess performance or make decisions to allocate resources.  Therefore, depreciation and amortization expense is not allocated among segments.  General and administrative expenses and interest expense are not included in segment profit as our internal reporting addresses these items on a corporate level.

Accounting Policies [Abstract]	'
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, 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.
Investment in Real Estate Properties	'
	Investment in Real Estate Properties
	The properties are carried at cost less accumulated depreciation and amortization. The Company assigns the cost of an acquisition, including the assumption of liabilities, to the acquired tangible assets and identifiable intangible assets and liabilities based on their estimated fair values in accordance with GAAP. The Company assesses fair value based on estimated cash flow projections that utilize discount and/or capitalization rates and available market information. 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 was vacant.
	Acquisition-related expenses associated with acquisition of operating properties are expensed in the period incurred.
	The Company records acquired above- and below- market leases at fair value using 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 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 capitalizes direct construction and development costs, including predevelopment costs, interest, property taxes, insurance and other costs directly related and essential to the acquisition, development or construction of a real estate project. Indirect development costs, including salaries and benefits, office rent, and associated costs for those individuals directly responsible for and who spend their time on development activities are also capitalized and allocated to the projects to which they relate. Capitalized personnel costs for the three and nine months ended September 30, 2014 were approximately $0.8 million and $2.1 million, respectively, and $0.5 million and $1.5 million for the three and nine months ended September 30, 2013, respectively. Interest is capitalized on the construction in progress at a rate equal to the Company’s weighted average cost of debt. Capitalized interest for the three and nine months ended September 30, 2014 was approximately $1.9 million and $5.2 million, respectively, and $1.1 million and $2.8 million for the three and nine months ended September 30, 2013, respectively. Construction and development costs are capitalized while substantial activities are ongoing to prepare an asset for its intended use. The Company considers a construction project as substantially complete and held available for occupancy upon the completion of tenant improvements but no later than one year after cessation of major construction activity. Costs incurred after a project is substantially complete and ready for its intended use, or after development activities have ceased, are expensed as they are incurred. Costs previously capitalized related to abandoned acquisitions or developments are charged to earnings. Expenditures for repairs and maintenance are expensed as they are incurred.
Depreciation	'
	The Company computes depreciation using the straight-line method over the estimated useful lives of 39 years for building and improvements, 15 years for land improvements, 5 to 7 years for furniture and fixtures and equipment, and over the shorter of asset life or life of the lease for tenant improvements. Above- and below-market lease intangibles are amortized to revenue over the remaining non-cancellable lease terms and bargain renewal periods, if applicable. Other in-place lease intangibles are amortized to expense over the remaining non-cancellable lease term. Depreciation is discontinued when a property is identified as held for sale.
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	The Company assesses the carrying value of real estate assets and related intangibles whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable in accordance with GAAP. Impairment losses are recorded on real estate assets held for investment when indicators of impairment are present and the future undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount. The Company recognizes impairment losses to the extent the carrying amount exceeds the fair value of the properties. Properties held for sale are recorded at the lower of cost or estimated fair value less cost to sell.
Goodwill	'
	Goodwill
	Goodwill represents the excess of acquisition cost over the fair value of net tangible and identifiable intangible assets acquired and liabilities assumed in business combinations. Our goodwill balance as of September 30, 2014 was $8.8 million. We do not amortize this asset but instead analyze it on an annual basis for impairment.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents are defined as cash on hand and in banks, plus all short-term investments with a maturity of three months or less when purchased.
	The Company maintains some of its cash in bank deposit accounts that, at times, may exceed the federally insured limit. No losses have been experienced related to such accounts.
Restricted Cash	'
	Restricted Cash
	Restricted cash consists of amounts held by lenders to provide for future real estate taxes and insurance expenditures, repairs and capital improvements reserves, general and other reserves and security deposits.
Accounts Receivable and Allowance for Doubtful Accounts	'
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable consist of amounts due for monthly rents and other charges. The Company maintains an allowance for doubtful accounts for estimated losses resulting from tenant defaults or the inability of tenants to make contractual rent and tenant recovery payments. The Company monitors the liquidity and creditworthiness of its tenants and operators on an ongoing basis. This evaluation considers industry and economic conditions, property performance, credit enhancements and other factors. For straight-line rent amounts, the Company’s assessment is based on amounts estimated to be recoverable over the term of the lease. At September 30, 2014 and December 31, 2013, the Company had reserved $0.5 million and $0.3 million, respectively, of straight-line receivables. The Company evaluates the collectability of accounts receivable based on a combination of factors. The allowance for doubtful accounts is based on specific identification of uncollectible accounts and the Company’s historical collection experience. The Company recognizes an allowance for doubtful accounts based on the length of time the receivables are past due, the current business environment and the Company’s historical experience. Historical experience has been within management’s expectations.
Revenue Recognition	'
	Revenue Recognition
	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. If the lease provides for tenant improvements, the Company determines whether the tenant improvements, for accounting purposes, are owned by the tenant or the Company. When the Company is the owner of the tenant improvements, the tenant is not considered to have taken physical possession or have control of the physical use of the leased asset until the tenant improvements are substantially completed. When the tenant is the owner of the tenant improvements, any tenant improvement allowance that is funded is treated as a lease incentive and amortized as a reduction of revenue over the lease term. Tenant improvement ownership is determined based on various factors including, but not limited to:
	•	whether the lease stipulates how and on what a tenant improvement allowance may be spent;
	•	whether the tenant or landlord retains legal title to the improvements at the end of the lease term;
	•	whether the tenant improvements are unique to the tenant or general-purpose in nature; and
	•	whether the tenant improvements are expected to have any residual value at the end of the lease.
	Certain leases provide for additional rents contingent upon a percentage of the tenant’s revenue in excess of specified base amounts or other thresholds. Such revenue is recognized when actual results reported by the tenant, or estimates of tenant results, exceed the base amount or other thresholds. Such revenue is recognized only after the contingency has been removed (when the related thresholds are achieved), which may result in the recognition of rental revenue in periods subsequent to when such payments are received.
	Other property-related revenue is revenue that is derived from the tenants’ use of lighting, equipment rental, parking, power, HVAC and telecommunications (phone and Internet). Other property-related revenue is recognized when these items are provided.
	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.
	The Company recognizes gains on sales of properties upon the closing of the transaction with the purchaser. Gains on properties sold are recognized using the full accrual method when (i) the collectability of the sales price is reasonably assured, (ii) the Company is not obligated to perform significant activities after the sale, (iii) the initial investment from the buyer is sufficient and (iv) other profit recognition criteria have been satisfied. Gains on sales of properties may be deferred in whole or in part until the requirements for gain recognition have been met.
Deferred Financing Costs	'
	Deferred Financing Costs
	Deferred financing costs are amortized over the term of the respective loan.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	The Company manages interest rate risk associated with borrowings by entering into interest rate derivative contracts. The Company recognizes all derivatives on the consolidated balance sheet at fair value. Derivatives that are not hedges are adjusted to fair value and the changes in fair value are reflected as income or expense. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings, or recognized in other comprehensive income, which is a component of equity. The ineffective portion of a derivative’s change in fair value is immediately recognized in earnings.
Stock Based Compensation	'
	Stock-Based Compensation
	Accounting Standard Codification, (“ASC”), Topic 718, Compensation—Stock Compensation (“ASC 718”), requires us to recognize an expense for the fair value of equity-based compensation awards. Grants of stock options, restricted stock, restricted stock units and performance units under our equity incentive award plans are accounted for under ASC 718. Our compensation committee regularly considers the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our equity incentive award plans and programs.
Income Taxes	'
	Income Taxes
	Our taxable income prior to the completion of our IPO is reportable by the members of the limited liability companies that comprise our predecessor. Our property-owning subsidiaries are limited liability companies and are treated as pass-through entities for 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.
	We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) commencing with our initial taxable year. To qualify as a REIT, we are required to distribute at least 90% of our REIT taxable income to our stockholders and meet the various other requirements imposed by the Code relating to such matters as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we qualify for taxation as a REIT, we are generally not subject to corporate-level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. If we fail to qualify as a REIT in any taxable year, and are unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax.
	We have elected, together with one of our subsidiaries, to treat such subsidiary as a taxable REIT subsidiary (“TRS”) for federal income tax purposes. Certain activities that we undertake must be conducted by a TRS, such as non-customary services for our tenants and holding assets that we cannot hold directly. A TRS is subject to federal and state income taxes.
	The Company is subject to the statutory requirements of the states in which it conducts business.
	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, 2014, the Company had not established a liability for uncertain tax positions.
Fair Value of Assets and Liabilities	'
	Fair Value of Assets and Liabilities
	Under GAAP, the Company is required to measure certain financial instruments at fair value on a recurring basis. In addition, the Company is required to measure other financial instruments and balances at fair value on a non-recurring basis (e.g., carrying value of impaired real estate and long-lived assets). Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. 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 requires inputs that are both significant to the fair value measurement and unobservable.
	When available, the Company utilizes quoted market prices from an independent third-party source to determine fair value and classifies such items in Level 1 or Level 2. In instances where the market for a financial instrument is not active, regardless of the availability of a nonbinding quoted market price, observable inputs might not be relevant and could require the Company to make a significant adjustment to derive a fair value measurement. Additionally, in an inactive market, a market price quoted from an independent third party may rely more on models with inputs based on information available only to that independent third party. When the Company determines the market for a financial instrument owned by the Company to be illiquid or when market transactions for similar instruments do not appear orderly, the Company uses several valuation sources (including internal valuations, discounted cash flow analysis and quoted market prices) and establishes a fair value by assigning weights to the various valuation sources.
	Changes in assumptions or estimation methodologies can have a material effect on these estimated fair values. In this regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in an immediate settlement of the instrument.
	The Company considers the following factors to be indicators of an inactive market: (i) there are few recent transactions, (ii) price quotations are not based on current information, (iii) price quotations vary substantially either over time or among market makers (for example, some brokered markets), (iv) indexes that previously were highly correlated with the fair values of the asset or liability are demonstrably uncorrelated with recent indications of fair value for that asset or liability, (v) there is a significant increase in implied liquidity risk premiums, yields, or performance indicators (such as delinquency rates or loss severities) for observed transactions or quoted prices when compared with the Company’s estimate of expected cash flows, considering all available market data about credit and other nonperformance risk for the asset or liability, (vi) there is a wide bid-ask spread or significant increase in the bid-ask spread, (vii) there is a significant decline or absence of a market for new issuances (that is, a primary market) for the asset or liability or similar assets or liabilities, and (viii) little information is released publicly (for example, a principal-to-principal market).
	The Company considers the following factors to be indicators of non-orderly transactions: (i) there was not adequate exposure to the market for a period before the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities under current market conditions, (ii) there was a usual and customary marketing period, but the seller marketed the asset or liability to a single market participant, (iii) the seller is in or near bankruptcy or receivership (that is, distressed), or the seller was required to sell to meet regulatory or legal requirements (that is, forced), and (iv) the transaction price is an outlier when compared with other recent transactions for the same or similar assets or liabilities.
	The Company’s interest rate contract agreements are classified as Level 2 and their fair value is derived from estimated values obtained from observable market data for similar instruments.
Recently Issued Accounting Literature	'
	Recently Issued Accounting Literature
	Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of an Accounting Standards Update (“ASU”). We consider the applicability and impact of all ASUs. Recently issued ASUs not listed below are not expected to have a material impact on our consolidated financial position and results of operations, because either the ASU is not applicable or the impact is expected to be immaterial.
	On June 19, 2014, the FASB issued their final standard to amend the accounting guidance for stock compensation tied to performance targets (ASU No. 2014-12). The issue is the result of a consensus of the FASB Emerging Issues Task Force (Issue No. 13-D). The standard requires that a performance target that could be achieved after the requisite service period be treated as a performance condition, and as a result, this type of performance condition may delay expense recognition until achievement of the performance target is probable. The ASU is effective for all entities for reporting periods (including interim periods) beginning after December 15, 2015, and early adoption is permitted. The Company will adopt the guidance effective January 1, 2016 and the guidance is not expected to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.
	On May 28, 2014, the FASB issued their final standard on revenue from contracts with customers. The guidance specifically notes that lease contracts with customers are a scope exception. The standard (ASU No. 2014-09) outlines a single comprehensive model for entities to use in accounting for revenues arising from contracts with customers. The ASU is effective for annual reporting periods (including interim periods) beginning after December 15, 2016, and early adoption is not permitted. The Company will adopt the guidance effective January 1, 2017 and is currently assessing the impact on our consolidated financial statements and notes to our consolidated financial statements.
	On April 10, 2014, the FASB issued final guidance to change the criteria for reporting discontinued operations while enhancing disclosures in this area (ASU No. 2014-08). Under the new guidance, only disposals representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held for sale should be reported as discontinued operations. The guidance also expands the disclosure requirements for discontinued operations and adds new disclosures for individually significant dispositions that do not qualify as discontinued operations. The guidance will be applied prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The guidance is effective for annual financial statements with fiscal years beginning on or after December 15, 2014 with early adoption permitted for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. As of January 1, 2014, we have early adopted the amended guidance and the result did not have a meaningful impact on our consolidated financial position or results of operations.
