Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization and Ownership | Organization and Ownership Kilroy Realty Corporation (the “Company”) is a self-administered real estate investment trust (“REIT”) active in premier office and mixed-use submarkets along the West Coast. We own, develop, acquire and manage real estate assets, consisting primarily of Class A properties in the coastal regions of Greater Los Angeles, Orange County, San Diego County, the San Francisco Bay Area and Greater Seattle, which we believe have strategic advantages and strong barriers to entry. Class A real estate encompasses attractive and efficient buildings of high quality that are attractive to tenants, are well-designed and constructed with above-average material, workmanship and finishes and are well-maintained and managed. We qualify as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). The Company’s common stock is publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “KRC.” We own our interests in all of our real estate assets through Kilroy Realty, L.P. (the “Operating Partnership”) and Kilroy Realty Finance Partnership, L.P. (the “Finance Partnership”). We generally conduct substantially all of our operations through the Operating Partnership. Unless stated otherwise or the context indicates otherwise, the terms “Kilroy Realty Corporation” or the “Company,” “we,” “our,” and “us” refer to Kilroy Realty Corporation and its consolidated subsidiaries and the term “Operating Partnership” refers to Kilroy Realty, L.P. and its consolidated subsidiaries. The descriptions of our business, employees, and properties apply to both the Company and the Operating Partnership. Our stabilized portfolio of operating properties was comprised of the following properties at December 31, 2018 : Number of Buildings Rentable Square Feet (unaudited) Number of Tenants Percentage Occupied (unaudited) Percentage Leased (unaudited) Stabilized Office Properties 94 13,232,580 482 94.4 % 96.6 % Number of Number of Units 2018 Average Occupancy Stabilized Residential Property 1 200 79.7 % Our stabilized portfolio includes all of our properties with the exception of development and redevelopment properties currently committed for construction, under construction or in the tenant improvement phase, undeveloped land and real estate assets held for sale. We define redevelopment properties as those properties for which we expect to spend significant development and construction costs on the existing or acquired buildings pursuant to a formal plan, the intended result of which is a higher economic return on the property. We define properties in the tenant improvement phase as properties that we are developing or redeveloping where the project has reached cold shell condition and is ready for tenant improvements, which may require additional major base building construction before being placed in service. Projects in the tenant improvement phase are added to our stabilized portfolio once the project reaches the earlier of 95% occupancy or one year from the date of the cessation of major base building construction activities. Costs capitalized to construction in progress for development and redevelopment properties are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets at the historical cost of the property as the projects are placed in service. As of December 31, 2018 , the following properties were excluded from our stabilized portfolio. We did not have any redevelopment properties or properties held for sale at December 31, 2018 . Number of Properties/Projects Estimated Rentable Square Feet (1) (unaudited) In-process development projects - tenant improvement (2) 2 1,150,000 In-process development projects - under construction (3) 3 1,290,000 _______________ (1) Estimated rentable square feet upon completion. (2) Includes 88,000 square feet of Production, Distribution, and Repair (“PDR”) space. (3) In addition to the estimated office and PDR rentable square feet noted above, development projects under construction also include 96,000 square feet of retail space and 801 residential units. Our stabilized portfolio also excludes our future development pipeline, which as of December 31, 2018 was comprised of five potential development sites, representing approximately 73 gross acres of undeveloped land. As of December 31, 2018 , all of our properties and development projects were owned and all of our business was conducted in the state of California with the exception of eight office properties and one development project under construction located in the state of Washington. All of our properties and development projects are 100% owned, excluding four office properties owned by three consolidated property partnerships and an office property held by a consolidated variable interest entity for a transaction intended to qualify as a like-kind exchange pursuant to Section 1031 of the Code (“Section 1031 Exchange”) that closed in January 2019. Two of the three property partnerships, 100 First Street Member, LLC (“100 First LLC”) and 303 Second Street Member, LLC (“303 Second LLC”), each owned one office property in San Francisco, California through subsidiary REITs. As of December 31, 2018 , the Company owned a 56% common equity interest in both 100 First LLC and 303 Second LLC. The third property partnership, Redwood City Partners, LLC (“Redwood LLC”) owned two office properties in Redwood City, California. As of December 31, 2018 , the Company owned an approximate 93% common equity interest in Redwood LLC. The remaining interests in all three property partnerships were owned by unrelated third parties. As of December 31, 2018 , the Company owned an approximate 98.0% common general partnership interest in the Operating Partnership. The remaining approximate 2.0% common limited partnership interest in the Operating Partnership as of December 31, 2018 was owned by non-affiliated investors and certain of our executive officers and directors. Both the general and limited common partnership interests in the Operating Partnership are denominated in common units. Generally, the number of common units held by the Company is equivalent to the number of outstanding shares of the Company’s common stock, and the rights of all the common units to quarterly distributions and payments in liquidation mirror those of the Company’s common stockholders. The common limited partners have certain redemption rights as provided in the Operating Partnership’s Seventh Amended and Restated Agreement of Limited Partnership, as amended, the “Partnership Agreement”. Kilroy Realty Finance, Inc., which is a wholly-owned subsidiary of the Company, is the sole general partner of the Finance Partnership and owns a 1.0% common general partnership interest in the Finance Partnership. The Operating Partnership owns the remaining 99.0% common limited partnership interest. With the exception of the Operating Partnership and our consolidated property partnerships, all of our subsidiaries are wholly-owned. |

Basis of Presentation and Significant Accounting Policies [Abstract] | |
Basis of Presentation and Significant Accounting Policies | Basis of Presentation and Significant Accounting Policies Basis of Presentation The consolidated financial statements of the Company include the consolidated financial position and results of operations of the Company, the Operating Partnership, the Finance Partnership, 303 Second LLC, 100 First LLC, Redwood LLC and all of our wholly-owned and controlled subsidiaries. The consolidated financial statements of the Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, the Finance Partnership, 303 Second LLC, 100 First LLC, Redwood LLC and all of our wholly-owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements. Accounting Pronouncements Adopted January 1, 2018 Effective January 1, 2018, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2014-09 “Revenue From Contracts with Customers (Topic 606)” (“ASU 2014-09”) and the related FASB ASU Nos. 2016-12 and 2016-20, which provide practical expedients, technical corrections, and improvements for certain aspects of ASU 2014-09, on a modified retrospective basis. ASU 2014-09 establishes a single comprehensive model for entities to use in accounting for revenue from contracts with customers and supersedes most of the existing revenue recognition guidance. We evaluated each of the Company’s revenue streams to determine the sources of revenue that are impacted by ASU 2014-09 and concluded that two revenue streams, sales of real estate and revenue from our multi-tenant parking arrangements, fall within the scope of Topic 606. We evaluated the impact of the adoption of the guidance on the timing of gain recognition for our historical dispositions and concluded there was not a significant impact to our consolidated financial statements given the straight forward nature of our historical disposition transactions. We also evaluated the impact of the guidance on the timing and pattern of revenue recognition for our multi-tenant parking arrangements and determined there was no significant impact to our consolidated financial statements. We generally provide parking for our multi-tenant properties based on the prevailing market rate per parking space, which adjusts based on prevailing market rates during the tenant’s occupancy, and we recognize parking revenue as parking spaces are utilized by the tenant. Given the structure of these arrangements whereby the amount of parking revenue we recognize corresponds directly to the tenant’s use, we were able to apply the practical expedient provided in Accounting Standards Codification (“ASC”) 606-10-50-14(b) (the “right to invoice” practical expedient). As a result of applying this practical expedient, we are not required to disclose the transaction price allocated to future performance obligations for multi-tenant parking since we cannot predict or estimate the use of such parking spaces. During the years ended December 31, 2018 , 2017 and 2016 , we recognized $26.7 million , $26.7 million and $23.3 million , respectively, of parking revenue for arrangements that are within the scope of Topic 606, which is included in rental revenues on our consolidated statements of operations. We concluded that the adoption of Topic 606 did not have a material impact on our consolidated financial statements or a material impact on the notes to our consolidated financial statements. Effective January 1, 2018, we adopted FASB ASU No. 2017-09 “Compensation - Stock Compensation (Topic 718)” on a prospective basis. Under the guidance, an entity will not apply modification accounting to a share-based payment award if the award’s fair value, vesting conditions, and classification as an equity or liability instrument remain the same immediately before and after the change. The adoption of this guidance did not have an impact on our consolidated financial statements or notes to our consolidated financial statements. Effective January 1, 2018, we adopted FASB ASU No. 2017-05 “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20)” (“ASU 2017-05”) on a retrospective basis. This standard clarifies the scope of the original guidance within Subtopic 610-20 “Gains and Losses from the Derecognition of Nonfinancial Assets” that was issued in connection with ASU 2014-09 which provided guidance for recognizing gains and losses from the transfer of nonfinancial assets in transactions with noncustomers. Additionally, ASU 2017-05 adds guidance pertaining to the partial sales of real estate and clarifies that nonfinancial assets within the scope of ASC 610-20 may include nonfinancial assets transferred within a legal entity to a counterparty. For example, a parent may transfer control of nonfinancial assets by transferring ownership interests in a consolidated subsidiary. We evaluated the impact of the new amendments on our historical transactions and concluded that there was no impact. As such, the adoption of this guidance did not have an impact on our consolidated financial statements or notes to our consolidated financial statements. Effective January 1, 2018, we adopted FASB ASU No. 2016-15 (“ASU 2016-15”) which provides guidance where there is diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows, on a retrospective basis. The adoption of this guidance did not have an impact on our consolidated financial statements or notes to our consolidated financial statements. Effective January 1, 2018, we adopted FASB ASU No. 2016-01 (“ASU 2016-01”) which amends the accounting guidance on the classification and measurement of financial instruments and FASB ASU No. 2018-03 (“ASU 2018-03”) which provides technical corrections and improvements to ASU 2016-01, on a modified retrospective basis. The amendments require that all investments in equity securities, including other ownership interests, are reported at fair value with changes in fair value reported in net income. This requirement does not apply to investments that qualify for equity method accounting or to those that result in consolidation of the investee or for which the entity has elected the predictability exception to fair value measurement. Additionally, the amendments require that the portion of the total fair value change caused by a change in instrument-specific credit risk for financial liabilities for which the fair value option has been elected would be recognized in other comprehensive income. Any accumulated amount remaining in other comprehensive income is reclassified to earnings when the liability is extinguished. The adoption of this guidance did not have an impact on our consolidated financial statements or notes to our consolidated financial statements since our only financial instruments within the scope of ASU 2016-01 and 2018-03 are the marketable securities related to our deferred compensation plan which are classified as trading securities and marked to market at fair value through earnings each reporting period. Partially Owned Entities and Variable Interest Entities At December 31, 2018 the consolidated financial statements of the Company included three VIEs in addition to the Operating Partnership: 100 First LLC, 303 Second LLC and an entity established during the fourth quarter of 2018 to facilitate a Section 1031 Exchange. At December 31, 2018 , the Company and the Operating Partnership were determined to be the primary beneficiaries of these three VIEs since we had the ability to control the activities that most significantly impact each of the VIEs’ economic performance. As of December 31, 2018 , the three VIEs’ total assets, liabilities and noncontrolling interests included on our consolidated balance sheet were approximately $615.4 million (of which $543.9 million related to real estate held for investment), approximately $45.1 million and approximately $186.4 million , respectively. In January 2019, the Section 1031 Exchange was successfully completed and the related VIE was terminated. Revenues, income and net assets generated by 100 First LLC and 303 Second LLC may only be used to settle their contractual obligations, which primarily consist of operating expenses, capital expenditures and required distributions. At December 31, 2017 , the consolidated financial statements of the Company included two VIEs in addition to the Operating Partnership: 100 First LLC and 303 Second LLC. At December 31, 2017 , the impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests on our consolidated balance sheet by approximately $426.5 million (of which $382.1 million related to real estate held for investment on our consolidated balance sheet), approximately $27.3 million and approximately $175.4 million , respectively. The consolidated financial statements of the Operating Partnership included the same three VIEs at December 31, 2017 . Our accounting policy is to consolidate entities in which we have a controlling financial interest and significant decision making control over the entity's operations. In determining whether we have a controlling financial interest in a partially owned entity and the requirement to consolidate the accounts of that entity, we consider factors such as ownership interest, board representation, management representation, size of our investment (including loans), authority to control decisions, and contractual and substantive participating rights of the members. In addition to evaluating control rights, we consolidate entities in which the other members have no substantive kick-out rights to remove the Company as the managing member. Entities in which the equity investors do not have sufficient equity at risk to finance their endeavors without additional financial support or the holders of the equity investment at risk do not have a controlling financial interest are VIEs. We evaluate whether an entity is a VIE and whether we are the primary beneficiary. We are deemed to be the primary beneficiary of a VIE when we have the power to direct the activities of the VIE that most significantly impact the VIEs’ economic performance and the obligation to absorb losses or receive benefits that could potentially be significant to the VIE. If the requirements for consolidation are not met, the Company would account for investments under the equity method of accounting if we have the ability to exercise significant influence over the entity. Equity method investments would be initially recorded at cost and subsequently adjusted for our share of net income or loss and cash contributions and distributions each period. The Company did not have any equity method investments at December 31, 2018 or 2017 . Significant Accounting Policies Acquisitions Subsequent to our adoption of FASB ASU No. 2017-01 (“ASU 2017-01”) on January 1, 2017, which was adopted on a prospective basis, acquisitions of operating properties and development and redevelopment opportunities generally no longer meet the definition of a business and are accounted for as asset acquisitions. For these asset acquisitions, we record the acquired tangible and intangible assets and assumed liabilities based on each asset’s and liability’s relative fair value at the acquisition date of the total purchase price plus any capitalized acquisition costs. We record the acquired tangible and intangible assets and assumed liabilities of acquisitions of operating properties and development and redevelopment opportunities that meet the accounting criteria to be accounted for as business combinations at fair value at the acquisition date. The acquired assets and assumed liabilities for an acquisition generally include but are not limited to (i) land and improvements, buildings and improvements, undeveloped land and construction in progress and (ii) identified tangible and intangible assets and liabilities associated with in-place leases, including tenant improvements, leasing costs, value of above-market and below-market operating leases and ground leases, acquired in-place lease values and tenant relationships, if any. Any debt assumed and equity (including common units of the Operating Partnership) issued in connection with a property acquisition is recorded at fair value on the date of acquisition. The fair value of land and improvements is derived from comparable sales of land and improvements within the same submarket and/or region. The fair value of buildings and improvements, tenant improvements and leasing costs considers the value of the property as if it was vacant as well as current replacement costs and other relevant market rate information. The fair value of the above-market or below-market component of an acquired in-place operating lease is based upon the present value (calculated using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining non-cancellable lease term and (ii) our estimate of the rents that would be paid using fair market rental rates and rent escalations at the date of acquisition measured over the remaining non-cancellable term of the lease for above-market operating leases and the initial non-cancellable term plus the term of any below-market fixed rate renewal options, if applicable, for below-market operating leases. Our below-market operating leases generally do not include fixed rate or below-market renewal options. The amounts recorded for above-market operating leases are included in deferred leasing costs and acquisition-related intangible assets, net on the balance sheet and are amortized on a straight-line basis as a reduction of rental income over the remaining term of the applicable leases. The amounts recorded for below-market operating leases are included in deferred revenue and acquisition-related intangible liabilities, net on the balance sheet and are amortized on a straight-line basis as an increase to rental income over the remaining term of the applicable leases plus the term of any below-market fixed rate renewal options, if applicable. The amortization of the below-market ground lease obligation is recorded as an increase to ground lease expense in the consolidated statements of operations for the periods presented. The amortization of the above-market ground lease obligation is recorded as a decrease to ground lease expense in the consolidated statements of operations for the periods presented. The fair value of acquired in-place leases is derived based on our assessment of lost revenue and costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased. The amount recorded for acquired in-place leases is included in deferred leasing costs and acquisition-related intangible assets, net on the balance sheet and amortized as an increase to depreciation and amortization expense over the remaining term of the applicable leases. Fully amortized intangible assets are written off each quarter. Subsequent to our adoption of ASU 2017-01 on January 1, 2017, transaction costs associated with our acquisitions are capitalized as part of the purchase price of the acquisition. Prior to our adoption of ASU 2017-01, costs associated with all operating property acquisitions and those development and redevelopment acquisitions that met the criteria to be accounted for as business combinations were expensed as incurred and costs associated with development acquisitions accounted for as asset acquisitions were capitalized as part of the cost of the asset. Operating Properties Operating properties are generally carried at historical cost less accumulated depreciation. Properties held for sale are reported at the lower of the carrying value or the fair value less estimated cost to sell. The cost of operating properties includes the purchase price or development costs of the properties. Costs incurred for the renovation and betterment of the operating properties are capitalized to our investment in that property. Maintenance and repairs are charged to expense as incurred. When evaluating properties to be held and used for potential impairment, we first evaluate whether there are any indicators of impairment for any of our properties. If any impairment indicators are present for a specific property, we then evaluate the regional market conditions that could reasonably affect the property. If there are negative changes and trends in that regional market, we then perform an undiscounted cash flow analysis and compare the net carrying amount of the property to the property’s estimated undiscounted future cash flow over the anticipated holding period. If the estimated undiscounted future cash flow is less than the net carrying amount of the property, we then perform an impairment loss calculation to determine if the fair value of the property is less than the net carrying value of the property. Our impairment loss calculation compares the net carrying amount of the property to the property’s estimated fair value, which may be based on estimated discounted future cash flow calculations or third-party valuations or appraisals. We would recognize an impairment loss if the asset’s net carrying amount exceeds the asset’s estimated fair value. If we were to recognize an impairment loss, the estimated fair value of the asset (less costs to sell for assets held for sale) would become its new cost basis. For a depreciable long-lived asset, the new cost basis would be depreciated (amortized) over the remaining useful life of that asset. Cost Capitalization All costs clearly associated with the development, redevelopment and construction of a property are capitalized as project costs, including internal compensation costs. In addition, the following costs are capitalized as project costs during periods in which activities necessary to prepare development and redevelopment properties for their intended use are in progress: pre-construction costs essential to the development of the property, interest, real estate taxes and insurance. • For office and retail development and redevelopment properties that are pre-leased, we cease capitalization when revenue recognition commences, which is upon substantial completion of tenant improvements deemed to be the Company’s asset for accounting purposes. • For office and retail development and redevelopment properties that are not pre-leased, we may not immediately build out the tenant improvements. Therefore, we cease capitalization when revenue recognition commences upon substantial completion of the tenant improvements deemed to be the Company's asset for accounting purposes, but in any event, no later than one year after the cessation of major construction activities. We also cease capitalization on a development or redevelopment property when activities necessary to prepare the property for its intended use have been suspended. • For office and retail development or redevelopment properties with multiple tenants and staged leasing, we cease capitalization and begin depreciation on the portion of the development or redevelopment property for which revenue recognition has commenced. • For residential development properties, we cease capitalization when the property is substantially complete and available for occupancy. Once major base building construction activities have ceased and the development or redevelopment property is placed in service, the costs capitalized to construction in progress are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets as the historical cost of the property. Depreciation and Amortization of Buildings and Improvements The costs of buildings and improvements and tenant improvements are depreciated using the straight-line method of accounting over the estimated useful lives set forth in the table below. Depreciation expense for buildings and improvements for the three years ended December 31, 2018 , 2017 , and 2016 was $198.6 million , $190.5 million , and $172.0 million , respectively. Asset Description Depreciable Lives Buildings and improvements 25 – 40 years Tenant improvements 1 – 20 years (1) ________________________ (1) Tenant improvements are amortized over the shorter of the lease term or the estimated useful life. Real Estate Assets Held for Sale, Dispositions and Discontinued Operations A real estate asset is classified as held for sale when certain criteria are met, including but not limited to the availability of the asset for immediate sale, the existence of an active program to locate a buyer and the probable sale or transfer of the asset within one year. If such criteria are met, we present the applicable assets and liabilities related to the real estate asset held for sale, if material, separately on the balance sheet and we would cease to record depreciation and amortization expense. Real estate assets held for sale are reported at the lower of their carrying value or their estimated fair value less the estimated costs to sell. As of December 31, 2018 and 2017 , we did not have any properties classified as held for sale. Property disposals representing a strategic shift that have (or will have) a major effect on the Company’s operations and financial results, such as a major line of business, a major geographical area or a major equity investment, are required to be presented as discontinued operations. If we were to determine that a property disposition represents a strategic shift, the revenues, expenses and net gain (loss) on dispositions of the property would be recorded in discontinued operations for all periods presented through the date of the applicable disposition. The operations of the eleven , eleven and six properties sold during the years ended December 31, 2018 , December 31, 2017 and December 31, 2016 , respectively, are presented in continuing operations as they did not represent a strategic shift in the Company’s operations and financial results. The net gains (losses) on dispositions of non-depreciable real estate property, including land, are reported in the consolidated statements of operations as gains (losses) on sale of land within continuing operations in the period the land is sold. The net gains (losses) on dispositions of depreciable real estate property are reported in the consolidated statements of operations as gains on sales of depreciable operating properties within continuing operations in the period the land is sold. Revenue Recognition We recognize revenue from rent, tenant reimbursements, parking and other revenue once all of the following criteria are met: (i) the agreement has been fully executed and delivered, (ii) services have been rendered, (iii) the amount is fixed or determinable and (iv) the collectability of the amount is reasonably assured. Minimum annual rental revenues are recognized in rental revenues on a straight-line basis over the non-cancellable term of the related lease. Rental revenue recognition commences when the tenant takes possession or controls the physical use of the leased space. In order for the tenant to take possession, the leased space must be substantially complete and ready for its intended use. In order to determine whether the leased space is substantially ready for its intended use, we begin by determining whether the Company or the tenant owns the tenant improvements. When we conclude that the Company is the owner of tenant improvements, rental revenue recognition begins when the tenant takes possession of the finished space, which is generally when Company owned tenant improvements are substantially complete. In certain instances, when we conclude that the Company is not the owner (the tenant is the owner) of tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the space. When we conclude that the Company is the owner of tenant improvements, we record the cost to construct the tenant improvements, including costs paid for or reimbursed by the tenants, as a capital asset. For these tenant improvements, we record the amount funded by or reimbursed by the tenants as deferred revenue, which is amortized on a straight-line basis as additional rental income over the term of the related lease. When we conclude that the tenant is the owner of tenant improvements for accounting purposes, we record our contribution towards those improvements as a lease incentive, which is included in deferred leasing costs and acquisition-related intangible assets, net on our consolidated balance sheets and amortized as a reduction to rental income on a straight-line basis over the term of the lease. For residential properties, we commence revenue recognition upon lease commencement. Residential rental revenue is recognized on a straight-line basis over the term of the related lease, net of any concessions. Tenant Reimbursements Reimbursements from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs, are recognized as revenue in the period the recoverable costs are incurred. Tenant reimbursements are generally recognized and recorded on a gross basis, as we are generally the primary obligor with respect to purchasing goods and services from third-party suppliers, have discretion in selecting the supplier, and have credit risk. Other Property Income Other property income primarily includes amounts recorded in connection with lease terminations, tenant bankruptcy settlement payments, broken deal income and property damage settlement related payments. Lease termination fees are amortized over the remaining lease term, if applicable. If there is no remaining lease term, they are recognized when received and realized. Other property income also includes miscellaneous income from tenants, such as fees related to the restoration of leased premises to their original condition and fees for late rental payments. Allowances for Uncollectible Tenant and Deferred Rent Receivables We carry our current and deferred rent receivables net of allowances for uncollectible amounts. Our determination of the adequacy of these allowances is based primarily upon evaluations of individual receivables, current economic conditions, and other relevant factors. The allowances are increased or decreased through the provision for bad debts on our consolidated statements of operations. We also evaluate allowances for all other receivables which includes note receivables included in prepaid expenses and other assets on our consolidated balances sheets. Cash and Cash Equivalents We consider all highly-liquid investments with original maturities of three months or less to be cash equivalents. Restricted Cash Restricted cash consists of cash proceeds from dispositions that are temporarily held at qualified intermediaries for purposes of facilitating potential Section 1031 Exchanges and cash held in escrow related to acquisition and disposition holdbacks. Restricted cash also includes cash held as collateral to provide credit enhancement for the Operating Partnership’s mortgage debt, including cash reserves for capital expenditures, tenant improvements and property taxes. As of December 31, 2018 we had $113.1 million of restricted cash held at qualified intermediaries for the purpose of facilitating Section 1031 Exchanges. In January 2019, the Section 1031 Exchange was completed and the cash proceeds were released from the qualified intermediary. We did not have any restricted cash held at qualified intermediaries for the purpose of facilitating Section 1031 Exchanges at December 31, 2017 . Marketable Securities / Deferred Compensation Plan Marketable securities reported in our consolidated balance sheets represent the assets held in connection with the Kilroy Realty Corporation 2007 Deferred Compensation Plan (the “Deferred Compensation Plan”) (see Note 16 “Employee Benefit Plans” for additional information). The Deferred Compensation Plan assets are held in a limited rabbi trust and invested in various mutual and money market funds. As a result, the marketable securities are treated as trading securities for financial reporting purposes and are adjusted to fair value at the end of each accounting period, with the corresponding gains and losses recorded in interest income and other net investment gains (losses). At the time eligible management employees (“Participants”) defer compensation or earn mandatory Company contributions, or if we were to make a discretionary contribution, we record compensation cost and a corresponding deferred compensation plan liability, which is included in accounts payable, accrued expenses, and other liabilities on our consolidated balance sheets. This liability is adjusted to fair value at the end of each accounting period based on the performance of the benchmark funds selected by each Participant, and the impact of adjusting the liability to fair value is recorded as an increase or decrease to compensation cost. The impact of adjusting the deferred compensation plan liability to fair value and the changes in the value of the marketable securities held in connection with the Deferred Compensation Plan generally offset and therefore do not significantly impact net income. Deferred Leasing Costs Costs incurred in connection with successful property leasing are capitalized as deferred leasing costs and classified as investing activities in the statement of cash flows. Deferred leasing costs consist primarily of leasing commissions and also include certain internal payroll costs and lease incentives, which are amortized using the straight-line method of accounting over the lives of the leases which generally range from one to 20 years. We reevaluate the remaining useful lives of leasing costs as the creditworthiness of our tenants and economic and market conditions change. If we determine that the estimated remaining life of a lease has changed, we adjust the amortization period accordingly. Fully amortized deferred leasing costs are written off each quarter. As discussed below under “ Accounting Standards Issued But Not Yet Effective at December 31, 2018 ,” upon the adoption of FASB ASU No. 2016-02 “Leases (Topic 842),” most deferred leasing costs (with the exception of leasing commissions paid to external third party brokers) will no longer meet the criteria for capitalization. For leases commenced prior to December 31, 2018, these costs will continue to be amortized over the remaining life of the associated lease. For leases executed prior to December 31, 2018 that have not yet commenced as of December 31, 2018, such costs will be charged to distributions in excess of earnings as of January 1, 2019. Deferred Financing Costs Financing costs related to the origination or assumption of long-term debt are deferred and generally amortized using the straight-line method of accounting, which approximates the effective interest method, over the contractual terms of the applicable financings. Fully amortized deferred financing costs are written off when the corresponding financing is repaid. Debt Discounts and Premiums Original issuance debt discounts and discounts/premiums related to recording debt acquired in connection with operating property acquisitions at fair value are generally amortized and accreted on a straight-line basis, which approximates the effective interest method. Discounts are recorded as additional interest expense from date of issuance or acquisition through the contractual maturity date of the related debt. Premiums are recorded as a reduction to interest expense from the date of issuance or acquisition through the contractual maturity date of the related debt. Noncontrolling Interests - Common Units of the Operating Partnership in the Company's Consolidated Financial Statements Common units of the Operating Partnership within noncontrolling interests in the Company’s consolidated financial statements represent the common limited partnership interests in the Operating Partnership not held by the Company (“noncontrolling common units”). Noncontrolling common units are presented in the equity section of the Company’s consolidated balance sheets and are reported at their proportionate share of the net assets of the Operating Partnership. Noncontrolling interests with redemption provisions that permit the issuer to settle in either cash or shares of common stock must be further evaluated to determine whether equity or temporary equi |

The Company drew the full amount of the Series A Notes due 2026 on July 18, 2018. On October 22, 2018, the Company drew the full amount of the Series B Notes due 2026. The Series A and B Notes due 2026 mature on their respective due dates, unless earlier redeemed or prepaid pursuant to the terms of the 2018 Note Purchase Agreement. Interest on the Series A and B Notes due 2026 is payable semi-annually in arrears on April 18 and October 18 of each year beginning April 18, 2019 . As of December 31, 2018 , there was $50.0 million and $200.0 million issued and outstanding aggregate principal amount of Series A and Series B Notes due 2026, respectively.

The Series A and B Notes due 2027 and 2029 mature on their respective due dates unless earlier redeemed or prepaid pursuant to the terms of the 2016 Note Purchase Agreement. Interest on the Series A and B Notes due 2027 and 2029 is payable semi-annually in arrears on February 17 and August 17 of each year. As of December 31, 2018 , there was $175.0 million and $75.0 million issued and outstanding aggregate principal amount of Series A and B Notes, respectively.

In connection with the issuance of the Series A and B Notes due 2026 and Series A and B Notes due 2027 and 2029, the Company entered into an agreement whereby it will guarantee the payment by the Operating Partnership of all amounts due with respect to the Series A and B Notes due 2026 and Series A and B Notes due 2027 and the performance by the Operating Partnership of its obligations under the 2016 & 2018 Note Purchase Agreements. Unsecured Revolving Credit Facility and Term Loan Facility In July 2017, the Operating Partnership amended and restated the terms of its unsecured revolving credit facility and unsecured term loan facility (together, the “Facility”). The amendment and restatement increased the size of the unsecured revolving credit facility from $600.0 million to $750.0 million , maintained the size of the unsecured term loan facility of $150.0 million , reduced the borrowing costs and extended the maturity date of the Facility to July 2022. The following table summarizes the balance and terms of our unsecured revolving credit facility as of December 31, 2018 and 2017 : December 31, 2018 December 31, 2017 (in thousands) Outstanding borrowings $ 45,000 $ — Remaining borrowing capacity 705,000 750,000 Total borrowing capacity (1) $ 750,000 $ 750,000 Interest rate (2) 3.48 % 2.56 % Facility fee-annual rate (3) 0.200% Maturity date July 2022 _______________ (1) We may elect to borrow, subject to bank approval and obtaining commitments for any additional borrowing capacity, up to an additional $600.0 million under an accordion feature under the terms of the unsecured revolving credit facility and unsecured term loan facility. (2) Our unsecured revolving credit facility interest rate was calculated based on the contractual rate of LIBOR plus 1.000% as of December 31, 2018 and 2017 . (3) Our facility fee is paid on a quarterly basis and is calculated based on the total borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs. As of December 31, 2018 and 2017 , $4.7 million and $6.0 million of unamortized deferred financing costs, respectively, which are included in prepaid expenses and other assets, net on our consolidated balance sheets, remained to be amortized through the maturity date of our unsecured revolving credit facility. The Company intends to borrow under the unsecured revolving credit facility from time to time for general corporate purposes, to finance development and redevelopment expenditures, to fund potential acquisitions and to potentially repay long-term debt. During the first quarter of 2018, we borrowed the full $150.0 million borrowing capacity of our unsecured term loan facility. In connection with the funding of the outstanding borrowings, we transferred $30.0 million of outstanding borrowings under the unsecured revolving credit facility to the balance of our unsecured term loan facility. As a result, only $120.0 million of cash proceeds were received from the funding of the unsecured term loan facility. The following table summarizes the balance and terms of our unsecured term loan facility as of December 31, 2018 and 2017 : December 31, 2018 December 31, 2017 (in thousands) Outstanding borrowings $ 150,000 $ — Remaining borrowing capacity — 150,000 Total borrowing capacity (1) $ 150,000 $ 150,000 Interest rate (2) 3.49 % 2.66 % Undrawn facility fee-annual rate (3) 0.200% Maturity date July 2022 _______________ (1) As of December 31, 2018 and 2017 , $0.9 million and $1.2 million of unamortized deferred financing costs, respectively, remained to be amortized through the maturity date of our unsecured term loan facility. (2) Our unsecured term loan facility interest rate was calculated based on the contractual rate of LIBOR plus 1.100% as of December 31, 2018 and 2017 . (3) Prior to borrowing the full capacity of our unsecured term loan facility, the undrawn facility fee was calculated based on any unused borrowing capacity and was paid on a quarterly basis. Debt Covenants and Restrictions The unsecured revolving credit facility, the unsecured term loan facility, the unsecured senior notes, the Series A and B Notes due 2026 and Series A and B Notes due 2027 and 2029 and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. Some of the more restrictive financial covenants include a maximum ratio of total debt to total asset value, a minimum fixed-charge coverage ratio, a minimum unsecured debt ratio and a minimum unencumbered asset pool debt service coverage ratio. Noncompliance with one or more of the covenants and restrictions could result in the full principal balance of the associated debt becoming immediately due and payable. We believe we were in compliance with all of our debt covenants as of December 31, 2018 and 2017 . Debt Maturities The following table summarizes the stated debt maturities and scheduled amortization payments as of December 31, 2018 : Year (in thousands) 2019 $ 76,309 2020 5,137 2021 5,342 2022 200,554 2023 305,775 Thereafter 2,362,694 Total aggregate principal value (1) $ 2,955,811 ________________________ (1) Includes gross principal balance of outstanding debt before the effect of the following at December 31, 2018 : $17.4 million of unamortized deferred financing costs for the unsecured term loan facility, unsecured senior notes and secured debt, $6.6 million of unamortized discounts for the unsecured senior notes and $0.8 million of unamortized premiums for the secured debt.

Noncontrolling Interest [Abstract] | |
Noncontrolling Interests on the Company's Consolidated Financial Statements | Noncontrolling Interests on the Company’s Consolidated Financial Statements Common Units of the Operating Partnership The Company owned a 98.0% and 97.9% common general partnership interest in the Operating Partnership as of December 31, 2018 and 2017 , respectively. The remaining 2.0% and 2.1% common limited partnership interest as of December 31, 2018 and 2017 , respectively, was owned by non-affiliated investors and certain of our executive officers and directors in the form of noncontrolling common units. There were 2,025,287 and 2,077,193 common units outstanding held by these investors, executive officers and directors as of December 31, 2018 and 2017 , respectively. The decrease in the common units from December 31, 2017 to December 31, 2018 was attributable to 51,906 common unit redemptions. The noncontrolling common units may be redeemed by unitholders for cash. Except under certain circumstances, we, at our option, may satisfy the cash redemption obligation with shares of the Company’s common stock on a one-for-one basis. If satisfied in cash, the value for each noncontrolling common unit upon redemption is the amount equal to the average of the closing quoted price per share of the Company’s common stock, par value $.01 per share, as reported on the NYSE for the ten trading days immediately preceding the applicable redemption date. The aggregate value upon redemption of the then-outstanding noncontrolling common units was $126.4 million and $154.5 million as of December 31, 2018 and 2017 , respectively. This redemption value does not necessarily represent the amount that would be distributed with respect to each noncontrolling common unit in the event of our termination or liquidation. In the event of our termination or liquidation, it is expected in most cases that each common unit would be entitled to a liquidating distribution equal to the liquidating distribution payable in respect of each share of the Company’s common stock. Noncontrolling Interest in Consolidated Property Partnerships On August 30, 2016, the Operating Partnership entered into agreements with Norges Bank Real Estate Management (“NBREM”) whereby NBREM invested, through two REIT subsidiaries, in two existing companies that owned the Company’s 100 First Street and 303 Second Street office properties located in San Francisco, California. Based on a gross valuation of the properties of approximately $1.2 billion , NBREM contributed a total of $452.9 million , for a 44% common equity interest in the companies, which was net of approximately $55.3 million of its proportionate share of the existing mortgage debt on 303 Second Street as of the transaction date. In November 2017, NBREM contributed $54.4 million to fund their proportionate share of the Company’s repayment of this mortgage debt. The transaction was structured with a staggered closing. On August 30, 2016, the first tranche of the transaction closed and NBREM contributed $191.4 million plus a working capital contribution of $2.1 million for a 44% common ownership interest in 100 First LLC. On November 30, 2016, the second tranche of the transaction closed and NBREM contributed $261.5 million , which was net of its proportionate share of the existing mortgage debt secured by the 303 Second Street property of approximately $55.3 million , plus a working capital contribution of $2.9 million for a 44% common ownership interest in 303 Second LLC. The transactions did not meet the criteria to qualify as sales of real estate because the Company continues to effectively control the properties and therefore continued to account for the 100 First Street and 303 Second Street office properties on a consolidated basis in its financial statements. At formation, the Company accounted for the transactions as equity transactions and recognized noncontrolling interests in its consolidated balance sheets. In connection with the transaction, the Company provides customary property management, leasing and construction management services for both properties. 100 First Street is a 467,095 square foot office tower, and 303 Second Street is a 740,047 square foot office property, both located in the South of Market submarket in San Francisco, California. The noncontrolling interests in 100 First LLC and 303 Second LLC as of December 31, 2018 and 2017 were $186.4 million and $175.4 million , respectively, which is recognized in noncontrolling interests in consolidated property partnerships on the Company’s consolidated balance sheets. The remaining amount of noncontrolling interests in consolidated property partnerships represents the third party equity interest in Redwood LLC. This noncontrolling interest was $6.0 million and $6.2 million as of December 31, 2018 and 2017 , respectively. Noncontrolling Interests on the Operating Partnership’s Consolidated Financial Statements Consolidated Property Partnerships On August 30, 2016, the Operating Partnership entered into agreements with NBREM whereby NBREM invested, through two REIT subsidiaries, in two existing companies that owned the Company’s 100 First Street and 303 Second Street office properties located in San Francisco, California.

The redemption payment did not include any additional accrued dividends because the redemption date was also the dividend payment date. On March 30, 2017 (the “Series G Redemption Date”), the Company redeemed all 4,000,000 shares of its 6.875% Series G Cumulative Redeemable Preferred Stock (“Series G Preferred Stock”). The shares of Series G Preferred Stock were redeemed at a redemption price equal to their stated liquidation preference of $25.00 per share, representing $100.0 million in aggregate, plus all accrued and unpaid dividends to the Series G Redemption Date. In connection with the redemption of the Series G and Series H Preferred Stock, during the year ended December 31, 2017 we recorded non-cash charges of $7.6 million as a reduction to net income available to common stockholders for the original issuance costs of the Series H and Series G Preferred Stock. Common Stock Forward Equity Offering On August 8, 2018, the Company entered into forward equity sale agreements with certain financial institutions acting as forward purchasers in connection with an offering of 5,000,000 shares of common stock at an initial gross offering price of $360.5 million , or $72.10 per share, before underwriting discounts, commissions and offering expenses. The forward purchasers borrowed and sold an aggregate of 5,000,000 shares of common stock in the offering. The Company did not receive any proceeds from the sale of its shares of common stock by the forward purchasers at the time of the offering. The Company currently expects to fully physically settle the forward sale agreements and receive cash proceeds upon one or more settlement dates, at the Company’s discretion, prior to the final settlement date under the forward sale agreements of August 1, 2019. The forward sale price that we expect to receive upon physical settlement of the agreements, which was initially $71.68 per share, will be subject to adjustment for (i) a floating interest rate factor equal to a specified daily rate less a spread, (ii) the forward purchasers’ stock borrowing costs and (iii) scheduled dividends during the term of the forward equity sale agreements. The full amount of this offering remains available for future settlement as of the date of this filing. Upon issuance of shares, the Company will contribute the net proceeds from these issuances to the Operating Partnership in exchange for an equal number of units in the Operating Partnership. Common Stock Issuances In January 2017, the Company completed an underwritten public offering of 4,427,500 shares of its common stock. The net offering proceeds, after deducting underwriting discounts and offering expenses, were approximately $308.8 million . We used a portion of the proceeds to partially fund our $1.90 per share of special dividends declared by our Board of Directors in December 2016 and used the remaining proceeds for general corporate uses, to fund development expenditures and to repay outstanding indebtedness. At-The-Market Stock Offering Program Under our at-the-market stock offering programs, which commenced in December 2014 and June 2018 we may offer and sell shares of our common stock from time to time in “at-the-market” offerings. During the year ended December 31, 2018 , the Company completed its existing at-the-market stock offering program (the “2014 At-The-Market Program”) under which we sold an aggregate of $300.0 million in gross sales of shares, and in June 2018 commenced a new at-the-market stock offering program (the “2018 At-The-Market Program”) under which we may offer and sell shares of our common stock with an aggregate gross sales price of up to $500.0 million . In connection with the 2018 At-The-Market-Program, the Company may, at its discretion, enter into forward equity sale agreements. The use of a forward equity sale agreements would allow the Company to lock in a share price on the sale of shares of our common stock at the time the agreement is executed, but defer receiving the proceeds from the sale of shares until a later date, allowing the Company to better align such funding with its capital needs. The following table sets forth information regarding sales of our common stock under our at-the-market offering programs for the years ended December 31, 2018 , 2017 and 2016 : Year Ended December 31, 2018 2017 2016 (in millions, except share data) Shares of common stock sold during the period 1,817,195 235,077 451,398 Weighted average price per share of common stock $ 73.64 $ 75.40 $ 71.50 Aggregate gross proceeds $ 133.8 $ 17.7 $ 32.3 Aggregate net proceeds after selling commissions $ 132.1 $ 17.5 $ 31.9 The proceeds from sales were used to fund acquisitions, development expenditures and general corporate purposes including repayment of borrowings under the unsecured revolving credit facility. During the year ended December 31, 2018 , under the 2014 At-The-Market Program, we sold 1,369,729 shares of common stock and completed the program. Since commencement of the 2018 At-The-Market Program through December 31, 2018 , we have sold 447,466 shares of common stock, none of which were sold under forward equity sale agreements. Approximately $466.2 million remains available to be sold under this program. Actual future sales will depend upon a variety of factors, including, but not limited to, market conditions, the trading price of the Company’s common stock and our capital needs. We have no obligation to sell the remaining shares available for sale under the 2018 At-The-Market program. Common Stock Repurchases On February 23, 2016, the Company’s Board of Directors approved a 4,000,000 share increase to the Company’s existing share repurchase program bringing the total current repurchase authorization to 4,988,025 shares.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
Share-Based Compensation | hare-Based and Other Compensation Stockholder Approved Share-Based Incentive Compensation Plan As of December 31, 2018 , we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan, as amended (the “2006 Plan”). The Company has a currently effective registration statement registering 9.2 million shares of our common stock for possible issuance under our 2006 Incentive Award Plan. As of December 31, 2018 , approximately 0.6 million shares were available for grant under the 2006 Plan. The calculation of shares available for grant is presented after taking into account a reserve for a sufficient number of shares to cover the vesting and payment of 2006 Plan awards that were outstanding on that date, including performance-based vesting awards at (i) levels actually achieved for the performance conditions (as defined below) for which the performance period has been completed and (ii) at maximum levels for the other performance and market conditions (as defined below) for awards still in a performance period. The Executive Compensation Committee (the “Compensation Committee”) of the Company's Board of Directors may grant the following share-based awards to eligible individuals, as provided under the 2006 Plan: incentive stock options, nonqualified stock options, restricted stock (nonvested shares), stock appreciation rights, performance shares, performance stock units, dividend equivalents, stock payments, deferred stock, restricted stock units (“RSUs”), profit interest units, performance bonus awards, performance-based awards and other incentive awards. For each award granted under our share-based incentive compensation programs, the Operating Partnership simultaneously issues to the Company a number of common units equal to the number of shares of common stock ultimately paid by the Company in respect of such awards. 2018, 2017 and 2016 Share-Based Compensation Grants In connection with entering into an amended employment agreement (the “Amended Employment Agreement”), on December 27, 2018, the Compensation Committee of the Company’s Board of Directors awarded John Kilroy, the Chairman of the Board of Directors, Chief Executive Officer and President of the Company and the Operating Partnership 483,871 RSUs, providing an additional retention incentive during the term of the agreement and enticing Mr. Kilroy to delay his retirement. Of these RSUs awarded, 266,130 RSUs (at the target level of performance) are subject to market-based vesting requirements and 217,741 RSUs are subject to time-based vesting requirements. In addition to Mr. Kilroy’s award, the Compensation Committee of the Company’s Board of Directors awarded 161,290 RSUs to certain members of management. Of these RSUs awarded, 80,647 RSUs (at the target level of performance) are subject to market-based vesting requirements (together totaling 346,777 target RSUs with Mr. Kilroy’s award, the “December 2018 Market-Based RSUs”) and 80,643 RSUs are subject to time-based vesting requirements (together totaling 298,384 RSUs with Mr. Kilroy’s award, the “December 2018 Time-Based RSUs”). In January and February 2018 , the Executive Compensation Committee of the Company’s Board of Directors awarded 282,038 RSUs to certain officers of the Company under the 2006 Plan, which included 158,205 RSUs (at the target level of performance) that are subject to market and/or performance-based vesting requirements (the “2018 Performance-Based RSUs”) and 123,833 RSUs that are subject to time-based vesting requirements (the “2018 Time-Based RSUs”). Additionally, during 2018, 14,999 RSUs were granted to the board of directors and certain members of management subject to time vesting requirements. In February 2017 , the Executive Compensation Committee of the Company’s Board of Directors awarded 229,976 RSUs to certain officers of the Company under the 2006 Plan, which included 130,956 RSUs (at the target level of performance) that are subject to time-based, market-measure based and performance-based vesting requirements (the “2017 Performance-Based RSUs”) and 99,020 RSUs that are subject to time-based vesting requirements (the “2017 Time-Based RSUs”). Additionally, during 2017, 43,081 RSUs were granted to the board of directors and certain members of management subject to time vesting requirements. On January 28, 2016 , the Executive Compensation Committee of the Company’s Board of Directors awarded 294,821 RSUs to certain officers of the Company under the 2006 Plan, which included 168,077 RSUs (at the target level of performance) that are subject to time-based, market-measure based and performance-based vesting requirements (the “2016 Performance-Based RSUs”) and 126,744 RSUs that are subject to time-based vesting requirements (“2016 Time-Based RSUs”). Additionally, during 2016, 47,003 RSUs were granted to the board of directors and certain members of management subject to time vesting requirements. December 2018 Market-Based RSU Grant Between 0% and 200% of the total 346,777 target number of December 2018 Market-Based RSUs will be eligible to vest based on the Company’s relative total shareholder return (“TSR”) versus a comparative group of companies that consist of companies in the SNL US REIT Office Index over the performance period. An initial number of RSUs (the “Initial Number of RSUs”) will be determined at the end of 2021 based on a three -year performance period (2019 through 2021). Once the Initial Number of RSUs is determined, 75% of the Initial Number of RSUs will be scheduled to vest on January 5, 2022. The remaining 25% of the Initial Number of RSUs will be scheduled to vest on January 5, 2023, subject to adjustment based on the Company’s relative TSR for the entire four-year performance period (2019 through 2022). The December 2018 Market-Based RSUs are also subject to service vesting requirements through the scheduled vest dates. Each December 2018 Market-Based RSU represents the right to receive one share of our common stock in the future, subject to, and as modified by, the Company’s level of achievement of the applicable market conditions. The December 27, 2018 grant date fair value of the December 2018 Market-Based RSUs was $23.8 million . The fair value was calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below. For the year ended December 31, 2018 , we recorded compensation expense based upon the $68.66 grant date fair value per share. Compensation expense for the December 2018 Market-Based RSUs is recognized using a graded vesting approach, where 75% of the fair value will be recognized on a straight-line basis over the three-year initial performance period through the end of 2021, and the remaining 25% of the fair value will be recognized on a straight-line basis over the four-year final performance period through the end of 2022. The following table summarizes the assumptions utilized in the Monte Carlo simulation pricing models: December 2018 Market-Based RSU Award Fair Value Assumptions Valuation date December 27, 2018 Fair value per share on valuation date $68.66 Expected share price volatility 23.0% Risk-free interest rate 2.4% The computation of expected volatility was based on a blend of the historical volatility of our shares of common stock over a period of twice the performance period and implied volatility data based on the observed pricing of six month publicly-traded options on shares of our common stock. The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury STRIP securities in effect at December 27, 2018. 2018, 2017 and 2016 Annual Performance-Based RSU Grants The 2018 Performance-Based RSUs are scheduled to vest at the end of a three -year period (consisting of calendar years 2018-2020). A target number of 2018 Performance-Based RSUs were awarded, and the final number of 2018 Performance-Based RSUs that vest (which may be more or less than the target number) will be based upon (1) the achievement of pre-set FFO per share goals for the year ending December 31, 2018 that applies to 100% of the Performance-Based RSUs awarded (the “2018 FFO Performance Condition”) and (2) a performance measure that applies to 50% of the award based upon a measure of the Company’s average debt to EBITDA ratio for the three -year performance period (the “2018 Debt to EBITDA Ratio Performance Condition” and together with the 2018 FFO Performance Condition, the “2018 Performance Conditions”) and a market measure that applies to the other 50% of the award based upon the relative ranking of the Company’s TSR for the three -year performance period compared to the TSR of an established comparison group of companies over the same period (the “2018 Market Condition”). The 2018 Performance-Based RSUs are also subject to a three -year service vesting provision and are scheduled to cliff vest on the date the final vesting percentage is determined following the end of the three -year performance period under the awards. The 2018 FFO Performance Condition was achieved 175% of target for one participant and 150% of target for all other participants. The number of 2018 Performance-Based RSUs ultimately earned could fluctuate from the current estimated number of 2018 Performance-Based RSUs granted based upon the levels of achievement for the 2018 Debt to EBITDA Ratio Performance Condition, the 2018 Market Condition and the extent to which the service vesting condition is satisfied. The 2017 Performance-Based RSUs are scheduled to cliff vest at the end of a three -year period (consisting of calendar years 2017-2019) based upon (1) the achievement of pre-defined FFO per share goals for the year ended December 31, 2017 that applies to 100% of the 2017 Performance-Based RSUs awarded (the “2017 FFO Performance Condition”) and (2) also based upon either the average FAD per share growth that applies to 30% of the award or the Company’s average debt to EBITDA ratio that applies to a separate 30% of the award (together, the “Other 2017 Performance Conditions” and together with the 2017 FFO Performance Condition, the “2017 Performance Conditions”) or the relative TSR versus a comparative group of companies that consist of companies in the SNL US REIT Office Index that applies to the remaining 40% of the award (the “2017 Market Condition”) for the three -year period ending December 31, 2019. The 2017 FFO Performance Condition was achieved at a weighted average of approximately 131% of target for the 2017 Performance-Based RSUs. The number of 2017 Performance-Based RSUs ultimately earned could fluctuate from the current estimated number of 2017 Performance-Based RSUs granted based upon the levels of achievement for the Other 2017 Performance Conditions, the 2017 Market Condition and the extent to which the service vesting condition is satisfied. The 2016 Performance-Based RSUs are also scheduled to cliff vest at the end of a three -year service period based upon the achievement of pre-defined FFO per share goals for the year ended December 31, 2016 (the “2016 Performance Condition”) and also upon the average annual relative total stockholder return versus a comparative group of companies that consist of companies in the SNL US REIT Office Index (the “2016 Market Condition”) for the three -year period ending December 31, 2018. Based upon the combined results of the final 2016 Performance Condition and 2016 Market Condition, the 2016 Performance-Based RSUs achieved 144% of their target level of performance. As of December 31, 2018 , the estimated number of RSUs earned for the 2018 and 2017 Performance-Based RSUs and the actual number of RSUs earned for the 2016 Performance-Based RSUs was as follows: 2018 Performance-Based RSUs 2017 Performance-Based RSUs 2016 Performance-Based RSUs Service vesting period February 14, 2018 - January, 2021 February 24, 2017 - January, 2020 January 28, 2016 - January, 2019 Target RSUs granted 158,205 130,956 168,077 Estimated RSUs earned (1) 254,235 170,994 241,438 Date of valuation February 14, 2018 February 24, 2017 January 28, 2016 _______________ (1) Estimated RSUs earned for the 2018 Performance-Based RSUs are based on the actual achievement of the 2018 FFO Performance Condition and assumes target level achievement of the 2018 Debt to EBITDA Ratio Performance Condition and the 2018 Market Condition. Estimated RSUs earned for the 2017 Performance-Based RSUs are based on the actual achievement of the 2017 FFO Performance Condition and assume target level achievement of the 2017 Market Condition and Other 2017 Performance Conditions. The 2016 Performance-Based RSUs earned are based on actual performance of the 2016 Performance Condition and the 2016 Market Condition. Each Performance-Based RSU represents the right to receive one share of our common stock in the future, subject to, and as modified by, the Company’s level of achievement of the applicable performance and market conditions. The fair values of the 2018 Performance-Based RSUs, 2017 Performance-Based RSUs and 2016 Performance-Based RSUs were $10.8 million at February 14, 2018 , $10.3 million at February 24, 2017 and $9.6 million at January 28, 2016 , respectively. The fair values for the awards with market conditions were calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below. The determination of the fair value of the 2018, 2017 and 2016 Performance-Based RSUs takes into consideration the likelihood of achievement of the 2018, 2017 and 2016 Performance Conditions and the 2018, 2017 and 2016 Market Conditions, respectively, as discussed above. The following table summarizes the assumptions utilized in the Monte Carlo simulation pricing models: 2018 Award Fair Value Assumptions 2017 Award Fair Value Assumptions 2016 Award Fair Value Assumptions Valuation date February 14, 2018 February 24, 2017 January 28, 2016 Fair value per share on valuation date $70.08 $80.89 $57.08 Expected share price volatility 20.00% 21.00% 26.00% Risk-free interest rate 2.37% 1.39% 1.13% The computation of expected volatility was based on a blend of the historical volatility of our shares of common stock over a period of twice the remaining performance period as of the grant date and implied volatility data based on the observed pricing of six month publicly-traded options on shares of our common stock. The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury STRIP securities in effect at February 14, 2018 , February 24, 2017 and January 28, 2016 . Compensation expense for the Performance-Based RSUs is recognized on a straight-line basis over the requisite service period for each participant, which is generally the three-year service period. However, for one participant there was a shorter service period for their 2017 and 2018 Performance-Based RSUs. As of December 31, 2018 , the number of 2018 Performance-Based RSUs estimated to be earned based on the Company’s estimate of the performance conditions measured against the applicable goals was 254,235 , and the compensation cost recorded to date for this program was based on that estimate. For the portion of the 2018 Performance-Based RSUs subject to the 2018 Market Condition, for the year ended December 31, 2018 , we recorded compensation expense based upon the $70.08 fair value per share at February 14, 2018 . Compensation expense will be variable for the portion of the 2018 Performance-Based RSUs subject to the 2018 Debt to EBITDA Ratio Performance Condition, based upon the outcome of that condition. As of December 31, 2018 , the number of 2017 Performance-Based RSUs estimated to be earned based on the Company’s estimate of the performance conditions measured against the applicable goals was 170,994 , and the compensation cost recorded to date for this program was based on that estimate. For the portion of the 2017 Performance-Based RSUs subject to the 2017 Market Condition, for the years ended December 31, 2018 and 2017 , we recorded compensation expense based upon the $80.89 fair value per share at February 24, 2017 . Compensation expense will be variable for the portion of the 2017 Performance-Based RSUs subject to the Other 2017 Performance Conditions, based upon the outcome of those conditions. For the years ended December 31, 2018 , 2017 and 2016 , we recorded compensation expense for the 2016 Performance-Based RSUs based upon $57.08 fair value per share at January 28, 2016 multiplied by the 241,438 RSUs, which is net of forfeitures, estimated to be earned at December 31, 2016. December 2018 and Annual 2018, 2017 and 2016 Time-Based RSU Grants The annual 2018, 2017 and 2016 Time-Based RSUs are scheduled to vest in equal installments over the periods listed below. The December 2018 Time-Based RSUs are scheduled to vest 50% on January 5, 2022 and 50% on January 5, 2023.

Except as noted below, the Amended Employment Agreement continues Mr. Kilroy’s employment on terms substantially similar to those of the existing employment agreement, with a new term scheduled to continue through December 31, 2023. The Amended Employment Agreement includes a cash retirement benefit of $13.2 million , or $16.2 million for a retirement at or after attaining age 73 , with at least twelve months’ advance notice or at or after the end of the term of the agreement. For the year ended December 31, 2018, the Company recognized $12.1 million of compensation expense in general and administrative expenses on the consolidated statement of operations, representing the present value of the potential cash retirement benefit amount that was earned based on prior service. |

Retirement Benefits [Abstract] | |
Employee Benefit Plans | Employee Benefit Plans 401(k) Plan We have a retirement savings plan designed to qualify under Section 401(k) of the Code (the “401(k) Plan”). Our employees are eligible to participate in the 401(k) Plan on the first day of the month after three months of service. The 401(k) Plan allows eligible employees (“401(k) Participants”) to defer up to 60% of their eligible compensation on a pre-tax basis, subject to certain maximum amounts allowed by the Code. The 401(k) Plan provides for a matching contribution by the Company in an amount equal to 50 cents of each one dollar of participant contributions up to a maximum of 10% of the 401(k) Participant’s annual salary. 401(k) Participants vest immediately in the amounts contributed by us. For each of the years ended December 31, 2018 , 2017 , and 2016 , we contributed $1.5 million , $1.3 million and $1.2 million , respectively, to the 401(k) Plan. Deferred Compensation Plan In 2007, we adopted the Deferred Compensation Plan, under which directors and certain management employees may defer receipt of their compensation, including up to 70% of their salaries and up to 100% of their director fees and bonuses, as applicable. In addition, employee participants will receive mandatory Company contributions to their Deferred Compensation Plan accounts equal to 10% of their gross monthly salaries, without regard to whether such employees elect to defer salary or bonus compensation under the Deferred Compensation Plan. Our Board may, but has no obligation to, approve additional discretionary contributions by the Company to Participant accounts. We hold the Deferred Compensation Plan assets in a limited rabbi trust, which is subject to the claims of our creditors in the event of bankruptcy or insolvency. See Note 19 “Fair Value Measurements and Disclosures” for further discussion of our Deferred Compensation Plan assets as of December 31, 2018 and 2017 . Our liability of $21.7 million and $20.6 million under the Deferred Compensation Plan was fully funded as of December 31, 2018 and 2017 , respectively. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies General As of December 31, 2018 , we had commitments of approximately $960.1 million , excluding our ground lease commitments, for contracts and executed leases directly related to our operating and development properties. Ground Leases The following table summarizes our properties that are held subject to long-term noncancellable ground lease obligations and the respective contractual expiration dates: Property Contractual Expiration Date (1) 601 108th Ave NE, Bellevue, WA November 2093 701, 801 and 837 N. 34th Street, Seattle, WA (2) December 2041 1701 Page Mill Road and 3150 Porter Drive, Palo Alto, CA December 2067 Kilroy Airport Center Phases I, II, and III, Long Beach, CA July 2084 ____________________ (1) Reflects the contractual expiration date prior to the impact of any extension or purchase options held by the Company. (2) The Company has three 10 -year and one 45 -year extension options for this ground lease, which if exercised would extend the expiration date to December 2116. The minimum commitment under our ground leases as of December 31, 2018 for five years and thereafter is as follows: Year Ending (in thousands) 2019 $ 5,154 2020 5,154 2021 5,154 2022 5,154 2023 5,154 Thereafter 233,619 Total (1)(2)(3)(4)(5) $ 259,389 ________________________ (1) Excludes contingent future rent payments based on gross income or adjusted gross income and reflects the minimum ground lease obligations before the impact of ground lease extension options. (2) One of our ground lease obligations is subject to a fair market value adjustment every five years ; however, the lease includes ground rent subprotection and infrastructure rent credits which currently limit our annual rental obligations to $1.0 million . The contractual obligations for that ground lease included above assumes the lesser of $1.0 million or annual lease rental obligation in effect as of December 31, 2018 . (3) One of our ground lease obligations includes a component which is based on the percentage of gross income that exceeds the minimum ground rent. The minimum rent is subject to increases every five years based on 50% of the average annual percentage rent for the previous five years. The contractual obligations for that lease included above assume the current annual ground lease obligation in effect at December 31, 2018 for the remainder of the lease term since we cannot predict future adjustments. (4) One of our ground lease obligations is subject to a fair market value adjustment every five years based on a combination of CPI adjustments and third-party appraisals limited to maximum increases annually. The contractual obligations for that lease included above assume the current annual ground lease obligation in effect at December 31, 2018 for the remainder of the lease term since we cannot predict future adjustments. (5) One of our ground lease obligations includes a component which is based on the percentage of adjusted gross income that exceeds the minimum ground rent. The minimum rent is subject to increases every 10 years by an amount equal to 60% of the average annual percentage rent for the previous three years. The contractual obligations for this lease included above assume the current annual ground lease obligation in effect at December 31, 2018 for the remainder of the lease term since we cannot predict future adjustments. Environmental Matters We follow the policy of monitoring all of our properties, including acquisition, development, and existing stabilized portfolio properties, for the presence of hazardous or toxic substances. While there can be no assurance that a material environmental liability does not exist, we are not currently aware of any environmental liability with respect to our stabilized portfolio properties that would have a material adverse effect on our financial condition, results of operations and cash flow, or that we believe would require additional disclosure or the recording of a loss contingency. As of December 31, 2018 and 2017 , we had accrued environmental remediation liabilities of approximately $83.2 million and $28.3 million , respectively, recorded on our consolidated balance sheets in connection with certain of our in-process and future development projects. The accrued environmental remediation liabilities represent the remaining costs we estimate we will incur prior to and during the development process at various development acquisition sites. These estimates, which we developed with the assistance of third party experts, consist primarily of the removal of contaminated soil, performing environmental closure activities, constructing remedial systems, and other related costs since we are required to dispose of any existing contaminated soil, and sometimes perform other environmental closure or remedial activities, when we develop new buildings at these sites. We record estimated environmental remediation obligations for acquired properties at the acquisition date when we are aware of such costs and when such costs are probable of being incurred and can be reasonably estimated. Estimated costs related to development environmental remediation liabilities are recorded as an increase to the cost of the development project. Actual costs are recorded as a decrease to the liability when incurred. These accruals are adjusted as an increase or decrease to the development project costs and as an increase or decrease to the accrued environmental remediation liability if we obtain further information or circumstances change. The environmental remediation obligations recorded at December 31, 2018 and 2017 were not discounted to their present values since the amount and timing of cash payments are not fixed. It is possible that we could incur additional environmental remediation costs in connection with these development projects. However, potential additional environmental costs for these development projects cannot be reasonably estimated at this time and certain changes in estimates could occur as the site conditions, final project timing, design elements, actual soil conditions and other aspects of the projects, which may depend upon municipal and other approvals beyond the control of the Company, are determined. Other than the accrued environmental liabilities discussed above, we are not aware of any unasserted claims and assessments with respect to an environmental liability that we believe would require additional disclosure or the recording of an additional loss contingency. Litigation We and our properties are subject to litigation arising in the ordinary course of business. To our knowledge, neither we nor any of our properties are presently subject to any litigation or threat of litigation which, if determined unfavorably to us, would have a material adverse effect on our cash flow, financial condition, or results of operations. Insurance We maintain commercial general liability, auto liability, employers’ liability, umbrella/excess liability, special form property, difference in conditions including earthquake and flood, environmental, rental loss, and terrorism insurance covering all of our properties. Management believes the policy specifications and insured limits are reasonable given the relative risk of loss, the cost of the coverage, and industry practice. We do not carry insurance for generally uninsurable losses such as loss from governmental action, nuclear hazard, and war and military action. Policies are subject to various terms, conditions, and exclusions and some policies may involve large deductibles or co-payments. Property Damage Settlement During the year ended December 31, 2016 , we settled an outstanding property damage matter and received cash proceeds totaling $5.0 million , which is included in other property income on our consolidated statements of operations. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements and Disclosures | Fair Value Measurements and Disclosures Assets and Liabilities Reported at Fair Value The only assets we record at fair value on our consolidated financial statements are the marketable securities related to our Deferred Compensation Plan (see Note 16 “Employee Benefit Plans” for additional information).

We report the change in the fair value of the marketable securities at the end of each accounting period in interest income and other net investment (losses) gains in the consolidated statements of operations. We also adjust the related Deferred Compensation Plan liability to fair value at the end of each accounting period based on the performance of the benchmark funds selected by each participant, which results in a corresponding increase or decrease to compensation cost for the period. The following table sets forth the net (loss) gain on marketable securities recorded during the years ended December 31, 2018 , 2017 and 2016 : December 31, 2018 2017 2016 Description (in thousands) Net (loss) gain on marketable securities $ (1,851 ) $ 3,023 $ 1,130 Financial Instruments Disclosed at Fair Value The following table sets forth the carrying value and the fair value of our other financial instruments as of December 31, 2018 and 2017 : December 31, 2018 2017 Carrying Value Fair Value (1) Carrying Value Fair Value (1) (in thousands) Liabilities Secured debt, net $ 335,531 $ 335,885 $ 340,800 $ 346,858 Unsecured debt, net 2,552,070 2,546,386 2,006,263 2,077,199 Unsecured line of credit (1) 45,000 45,058 — — _______________ (1) Fair value calculated using Level II inputs, which are based on model-derived valuations in which significant inputs and significant value drivers are observable in active markets. |

Basis of Presentation and Significant Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The consolidated financial statements of the Company include the consolidated financial position and results of operations of the Company, the Operating Partnership, the Finance Partnership, 303 Second LLC, 100 First LLC, Redwood LLC and all of our wholly-owned and controlled subsidiaries. The consolidated financial statements of the Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, the Finance Partnership, 303 Second LLC, 100 First LLC, Redwood LLC and all of our wholly-owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements. |
Partially Owned Entities and Variable Interest Entities | Partially Owned Entities and Variable Interest Entities At December 31, 2018 the consolidated financial statements of the Company included three VIEs in addition to the Operating Partnership: 100 First LLC, 303 Second LLC and an entity established during the fourth quarter of 2018 to facilitate a Section 1031 Exchange. At December 31, 2018 , the Company and the Operating Partnership were determined to be the primary beneficiaries of these three VIEs since we had the ability to control the activities that most significantly impact each of the VIEs’ economic performance. As of December 31, 2018 , the three VIEs’ total assets, liabilities and noncontrolling interests included on our consolidated balance sheet were approximately $615.4 million (of which $543.9 million related to real estate held for investment), approximately $45.1 million and approximately $186.4 million , respectively. In January 2019, the Section 1031 Exchange was successfully completed and the related VIE was terminated. Revenues, income and net assets generated by 100 First LLC and 303 Second LLC may only be used to settle their contractual obligations, which primarily consist of operating expenses, capital expenditures and required distributions. At December 31, 2017 , the consolidated financial statements of the Company included two VIEs in addition to the Operating Partnership: 100 First LLC and 303 Second LLC. At December 31, 2017 , the impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests on our consolidated balance sheet by approximately $426.5 million (of which $382.1 million related to real estate held for investment on our consolidated balance sheet), approximately $27.3 million and approximately $175.4 million , respectively. The consolidated financial statements of the Operating Partnership included the same three VIEs at December 31, 2017 . Our accounting policy is to consolidate entities in which we have a controlling financial interest and significant decision making control over the entity's operations. In determining whether we have a controlling financial interest in a partially owned entity and the requirement to consolidate the accounts of that entity, we consider factors such as ownership interest, board representation, management representation, size of our investment (including loans), authority to control decisions, and contractual and substantive participating rights of the members. In addition to evaluating control rights, we consolidate entities in which the other members have no substantive kick-out rights to remove the Company as the managing member. Entities in which the equity investors do not have sufficient equity at risk to finance their endeavors without additional financial support or the holders of the equity investment at risk do not have a controlling financial interest are VIEs. We evaluate whether an entity is a VIE and whether we are the primary beneficiary. We are deemed to be the primary beneficiary of a VIE when we have the power to direct the activities of the VIE that most significantly impact the VIEs’ economic performance and the obligation to absorb losses or receive benefits that could potentially be significant to the VIE. If the requirements for consolidation are not met, the Company would account for investments under the equity method of accounting if we have the ability to exercise significant influence over the entity. Equity method investments would be initially recorded at cost and subsequently adjusted for our share of net income or loss and cash contributions and distributions each period. The Company did not have any equity method investments at December 31, 2018 or 2017 . |
Acquisitions | Acquisitions Subsequent to our adoption of FASB ASU No. 2017-01 (“ASU 2017-01”) on January 1, 2017, which was adopted on a prospective basis, acquisitions of operating properties and development and redevelopment opportunities generally no longer meet the definition of a business and are accounted for as asset acquisitions. For these asset acquisitions, we record the acquired tangible and intangible assets and assumed liabilities based on each asset’s and liability’s relative fair value at the acquisition date of the total purchase price plus any capitalized acquisition costs. We record the acquired tangible and intangible assets and assumed liabilities of acquisitions of operating properties and development and redevelopment opportunities that meet the accounting criteria to be accounted for as business combinations at fair value at the acquisition date. The acquired assets and assumed liabilities for an acquisition generally include but are not limited to (i) land and improvements, buildings and improvements, undeveloped land and construction in progress and (ii) identified tangible and intangible assets and liabilities associated with in-place leases, including tenant improvements, leasing costs, value of above-market and below-market operating leases and ground leases, acquired in-place lease values and tenant relationships, if any. Any debt assumed and equity (including common units of the Operating Partnership) issued in connection with a property acquisition is recorded at fair value on the date of acquisition. The fair value of land and improvements is derived from comparable sales of land and improvements within the same submarket and/or region. The fair value of buildings and improvements, tenant improvements and leasing costs considers the value of the property as if it was vacant as well as current replacement costs and other relevant market rate information. The fair value of the above-market or below-market component of an acquired in-place operating lease is based upon the present value (calculated using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining non-cancellable lease term and (ii) our estimate of the rents that would be paid using fair market rental rates and rent escalations at the date of acquisition measured over the remaining non-cancellable term of the lease for above-market operating leases and the initial non-cancellable term plus the term of any below-market fixed rate renewal options, if applicable, for below-market operating leases. Our below-market operating leases generally do not include fixed rate or below-market renewal options. The amounts recorded for above-market operating leases are included in deferred leasing costs and acquisition-related intangible assets, net on the balance sheet and are amortized on a straight-line basis as a reduction of rental income over the remaining term of the applicable leases. The amounts recorded for below-market operating leases are included in deferred revenue and acquisition-related intangible liabilities, net on the balance sheet and are amortized on a straight-line basis as an increase to rental income over the remaining term of the applicable leases plus the term of any below-market fixed rate renewal options, if applicable. The amortization of the below-market ground lease obligation is recorded as an increase to ground lease expense in the consolidated statements of operations for the periods presented. The amortization of the above-market ground lease obligation is recorded as a decrease to ground lease expense in the consolidated statements of operations for the periods presented. The fair value of acquired in-place leases is derived based on our assessment of lost revenue and costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased. The amount recorded for acquired in-place leases is included in deferred leasing costs and acquisition-related intangible assets, net on the balance sheet and amortized as an increase to depreciation and amortization expense over the remaining term of the applicable leases. Fully amortized intangible assets are written off each quarter. Subsequent to our adoption of ASU 2017-01 on January 1, 2017, transaction costs associated with our acquisitions are capitalized as part of the purchase price of the acquisition. Prior to our adoption of ASU 2017-01, costs associated with all operating property acquisitions and those development and redevelopment acquisitions that met the criteria to be accounted for as business combinations were expensed as incurred and costs associated with development acquisitions accounted for as asset acquisitions were capitalized as part of the cost of the asset. |
Operating Properties and Cost Capitalization | Operating Properties Operating properties are generally carried at historical cost less accumulated depreciation. Properties held for sale are reported at the lower of the carrying value or the fair value less estimated cost to sell. The cost of operating properties includes the purchase price or development costs of the properties. Costs incurred for the renovation and betterment of the operating properties are capitalized to our investment in that property. Maintenance and repairs are charged to expense as incurred. When evaluating properties to be held and used for potential impairment, we first evaluate whether there are any indicators of impairment for any of our properties. If any impairment indicators are present for a specific property, we then evaluate the regional market conditions that could reasonably affect the property. If there are negative changes and trends in that regional market, we then perform an undiscounted cash flow analysis and compare the net carrying amount of the property to the property’s estimated undiscounted future cash flow over the anticipated holding period. If the estimated undiscounted future cash flow is less than the net carrying amount of the property, we then perform an impairment loss calculation to determine if the fair value of the property is less than the net carrying value of the property. Our impairment loss calculation compares the net carrying amount of the property to the property’s estimated fair value, which may be based on estimated discounted future cash flow calculations or third-party valuations or appraisals. We would recognize an impairment loss if the asset’s net carrying amount exceeds the asset’s estimated fair value. If we were to recognize an impairment loss, the estimated fair value of the asset (less costs to sell for assets held for sale) would become its new cost basis. For a depreciable long-lived asset, the new cost basis would be depreciated (amortized) over the remaining useful life of that asset. Cost Capitalization All costs clearly associated with the development, redevelopment and construction of a property are capitalized as project costs, including internal compensation costs. In addition, the following costs are capitalized as project costs during periods in which activities necessary to prepare development and redevelopment properties for their intended use are in progress: pre-construction costs essential to the development of the property, interest, real estate taxes and insurance. • For office and retail development and redevelopment properties that are pre-leased, we cease capitalization when revenue recognition commences, which is upon substantial completion of tenant improvements deemed to be the Company’s asset for accounting purposes. • For office and retail development and redevelopment properties that are not pre-leased, we may not immediately build out the tenant improvements. Therefore, we cease capitalization when revenue recognition commences upon substantial completion of the tenant improvements deemed to be the Company's asset for accounting purposes, but in any event, no later than one year after the cessation of major construction activities. We also cease capitalization on a development or redevelopment property when activities necessary to prepare the property for its intended use have been suspended. • For office and retail development or redevelopment properties with multiple tenants and staged leasing, we cease capitalization and begin depreciation on the portion of the development or redevelopment property for which revenue recognition has commenced. • For residential development properties, we cease capitalization when the property is substantially complete and available for occupancy. Once major base building construction activities have ceased and the development or redevelopment property is placed in service, the costs capitalized to construction in progress are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets as the historical cost of the property. Depreciation and Amortization of Buildings and Improvements The costs of buildings and improvements and tenant improvements are depreciated using the straight-line method of accounting over the estimated useful lives set forth in the table below. |
Real Estate Assets Held for Sale, Dispositions and Discontinued Operations | Real Estate Assets Held for Sale, Dispositions and Discontinued Operations A real estate asset is classified as held for sale when certain criteria are met, including but not limited to the availability of the asset for immediate sale, the existence of an active program to locate a buyer and the probable sale or transfer of the asset within one year. If such criteria are met, we present the applicable assets and liabilities related to the real estate asset held for sale, if material, separately on the balance sheet and we would cease to record depreciation and amortization expense. Real estate assets held for sale are reported at the lower of their carrying value or their estimated fair value less the estimated costs to sell. As of December 31, 2018 and 2017 , we did not have any properties classified as held for sale. Property disposals representing a strategic shift that have (or will have) a major effect on the Company’s operations and financial results, such as a major line of business, a major geographical area or a major equity investment, are required to be presented as discontinued operations. If we were to determine that a property disposition represents a strategic shift, the revenues, expenses and net gain (loss) on dispositions of the property would be recorded in discontinued operations for all periods presented through the date of the applicable disposition. The operations of the eleven , eleven and six properties sold during the years ended December 31, 2018 , December 31, 2017 and December 31, 2016 , respectively, are presented in continuing operations as they did not represent a strategic shift in the Company’s operations and financial results. The net gains (losses) on dispositions of non-depreciable real estate property, including land, are reported in the consolidated statements of operations as gains (losses) on sale of land within continuing operations in the period the land is sold. The net gains (losses) on dispositions of depreciable real estate property are reported in the consolidated statements of operations as gains on sales of depreciable operating properties within continuing operations in the period the land is sold |
Revenue Recognition, Tenant Reimbursements and Other Property Income | Revenue Recognition We recognize revenue from rent, tenant reimbursements, parking and other revenue once all of the following criteria are met: (i) the agreement has been fully executed and delivered, (ii) services have been rendered, (iii) the amount is fixed or determinable and (iv) the collectability of the amount is reasonably assured. Minimum annual rental revenues are recognized in rental revenues on a straight-line basis over the non-cancellable term of the related lease. Rental revenue recognition commences when the tenant takes possession or controls the physical use of the leased space. In order for the tenant to take possession, the leased space must be substantially complete and ready for its intended use. In order to determine whether the leased space is substantially ready for its intended use, we begin by determining whether the Company or the tenant owns the tenant improvements. When we conclude that the Company is the owner of tenant improvements, rental revenue recognition begins when the tenant takes possession of the finished space, which is generally when Company owned tenant improvements are substantially complete. In certain instances, when we conclude that the Company is not the owner (the tenant is the owner) of tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the space. When we conclude that the Company is the owner of tenant improvements, we record the cost to construct the tenant improvements, including costs paid for or reimbursed by the tenants, as a capital asset. For these tenant improvements, we record the amount funded by or reimbursed by the tenants as deferred revenue, which is amortized on a straight-line basis as additional rental income over the term of the related lease. When we conclude that the tenant is the owner of tenant improvements for accounting purposes, we record our contribution towards those improvements as a lease incentive, which is included in deferred leasing costs and acquisition-related intangible assets, net on our consolidated balance sheets and amortized as a reduction to rental income on a straight-line basis over the term of the lease. For residential properties, we commence revenue recognition upon lease commencement. Residential rental revenue is recognized on a straight-line basis over the term of the related lease, net of any concessions. Tenant Reimbursements Reimbursements from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs, are recognized as revenue in the period the recoverable costs are incurred. Tenant reimbursements are generally recognized and recorded on a gross basis, as we are generally the primary obligor with respect to purchasing goods and services from third-party suppliers, have discretion in selecting the supplier, and have credit risk. Other Property Income Other property income primarily includes amounts recorded in connection with lease terminations, tenant bankruptcy settlement payments, broken deal income and property damage settlement related payments. Lease termination fees are amortized over the remaining lease term, if applicable. If there is no remaining lease term, they are recognized when received and realized. Other property income also includes miscellaneous income from tenants, such as fees related to the restoration of leased premises to their original condition and fees for late rental payments. |
Allowances for Uncollectible Tenant and Deferred Rent Receivables | Allowances for Uncollectible Tenant and Deferred Rent Receivables We carry our current and deferred rent receivables net of allowances for uncollectible amounts. Our determination of the adequacy of these allowances is based primarily upon evaluations of individual receivables, current economic conditions, and other relevant factors. The allowances are increased or decreased through the provision for bad debts on our consolidated statements of operations. |
Cash and Cash Equivalents | Cash and Cash Equivalents We consider all highly-liquid investments with original maturities of three months or less to be cash equivalents |
Restricted Cash | Restricted Cash Restricted cash consists of cash proceeds from dispositions that are temporarily held at qualified intermediaries for purposes of facilitating potential Section 1031 Exchanges and cash held in escrow related to acquisition and disposition holdbacks. Restricted cash also includes cash held as collateral to provide credit enhancement for the Operating Partnership’s mortgage debt, including cash reserves for capital expenditures, tenant improvements and property taxes. As of December 31, 2018 we had $113.1 million of restricted cash held at qualified intermediaries for the purpose of facilitating Section 1031 Exchanges. In January 2019, the Section 1031 Exchange was completed and the cash proceeds were released from the qualified intermediary. We did not have any restricted cash held at qualified intermediaries for the purpose of facilitating Section 1031 Exchanges at December 31, 2017 . |
Marketable Securities | Marketable securities reported in our consolidated balance sheets represent the assets held in connection with the Kilroy Realty Corporation 2007 Deferred Compensation Plan (the “Deferred Compensation Plan”) (see Note 16 “Employee Benefit Plans” for additional information). The Deferred Compensation Plan assets are held in a limited rabbi trust and invested in various mutual and money market funds. As a result, the marketable securities are treated as trading securities for financial reporting purposes and are adjusted to fair value at the end of each accounting period, with the corresponding gains and losses recorded in interest income and other net investment gains (losses). |
Deferred Compensation Plan | At the time eligible management employees (“Participants”) defer compensation or earn mandatory Company contributions, or if we were to make a discretionary contribution, we record compensation cost and a corresponding deferred compensation plan liability, which is included in accounts payable, accrued expenses, and other liabilities on our consolidated balance sheets. This liability is adjusted to fair value at the end of each accounting period based on the performance of the benchmark funds selected by each Participant, and the impact of adjusting the liability to fair value is recorded as an increase or decrease to compensation cost. The impact of adjusting the deferred compensation plan liability to fair value and the changes in the value of the marketable securities held in connection with the Deferred Compensation Plan generally offset and therefore do not significantly impact net income. |
Deferred Leasing Costs | Deferred Leasing Costs Costs incurred in connection with successful property leasing are capitalized as deferred leasing costs and classified as investing activities in the statement of cash flows. Deferred leasing costs consist primarily of leasing commissions and also include certain internal payroll costs and lease incentives, which are amortized using the straight-line method of accounting over the lives of the leases which generally range from one to 20 years. We reevaluate the remaining useful lives of leasing costs as the creditworthiness of our tenants and economic and market conditions change. If we determine that the estimated remaining life of a lease has changed, we adjust the amortization period accordingly. Fully amortized deferred leasing costs are written off each quarter. As discussed below under “ Accounting Standards Issued But Not Yet Effective at December 31, 2018 ,” upon the adoption of FASB ASU No. 2016-02 “Leases (Topic 842),” most deferred leasing costs (with the exception of leasing commissions paid to external third party brokers) will no longer meet the criteria for capitalization. For leases commenced prior to December 31, 2018, these costs will continue to be amortized over the remaining life of the associated lease. For leases executed prior to December 31, 2018 that have not yet commenced as of December 31, 2018, such costs will be charged to distributions in excess of earnings as of January 1, 2019. |
Deferred Financing Costs, and Debt Discounts and Premiums | Deferred Financing Costs Financing costs related to the origination or assumption of long-term debt are deferred and generally amortized using the straight-line method of accounting, which approximates the effective interest method, over the contractual terms of the applicable financings. Fully amortized deferred financing costs are written off when the corresponding financing is repaid. Debt Discounts and Premiums Original issuance debt discounts and discounts/premiums related to recording debt acquired in connection with operating property acquisitions at fair value are generally amortized and accreted on a straight-line basis, which approximates the effective interest method. Discounts are recorded as additional interest expense from date of issuance or acquisition through the contractual maturity date of the related debt. Premiums are recorded as a reduction to interest expense from the date of issuance or acquisition through the contractual maturity date of the related debt. |
Noncontrolling Interest and Partnership Interests | Noncontrolling Interests - Common Units of the Operating Partnership in the Company's Consolidated Financial Statements Common units of the Operating Partnership within noncontrolling interests in the Company’s consolidated financial statements represent the common limited partnership interests in the Operating Partnership not held by the Company (“noncontrolling common units”). Noncontrolling common units are presented in the equity section of the Company’s consolidated balance sheets and are reported at their proportionate share of the net assets of the Operating Partnership. Noncontrolling interests with redemption provisions that permit the issuer to settle in either cash or shares of common stock must be further evaluated to determine whether equity or temporary equity classification on the balance sheet is appropriate. Since the common units contain such a provision, we evaluated the accounting guidance and determined that the common units qualify for equity presentation in the Company’s consolidated financial statements. Net income attributable to noncontrolling common units is allocated based on their relative ownership percentage of the Operating Partnership during the reported period. The noncontrolling interest ownership percentage is determined by dividing the number of noncontrolling common units by the total number of common units outstanding. The issuance or redemption of additional shares of common stock or common units results in changes to the noncontrolling interest percentage as well as the total net assets of the Company. As a result, all equity transactions result in an allocation between equity and the noncontrolling interest in the Company’s consolidated balance sheets and statements of equity to account for the changes in the noncontrolling interest ownership percentage as well as the change in total net assets of the Company. Noncontrolling Interests in Consolidated Property Partnerships Noncontrolling interests in consolidated property partnerships represent the equity interests held by unrelated third parties in our three consolidated property partnerships (see Note 11 “Noncontrolling Interests on the Company’s Consolidated Financial Statements” and see Note 12 “Noncontrolling Interests on the Operating Partnership’s Consolidated Financial Statements”). Noncontrolling interests in consolidated property partnerships are not redeemable and are presented as permanent equity in the Company's consolidated balance sheets. We account for the noncontrolling interests in consolidated property partnerships using the hypothetical liquidation at book value (“HLBV”) method to attribute the earnings or losses of the consolidated property partnerships between the controlling and noncontrolling interests. Under the HLBV method, the amounts reported as noncontrolling interests in consolidated property partnerships in the consolidated balance sheets represent the amounts the noncontrolling interests would hypothetically receive at each balance sheet reporting date under the liquidation provisions of the governing agreements assuming the net assets of the consolidated property partnerships were liquidated at recorded amounts and distributed between the controlling and noncontrolling interests in accordance with the governing documents. The net income attributable to noncontrolling interests in consolidated property partnerships in the consolidated statements of operations is associated with the increase or decrease in the noncontrolling interest holders’ contractual claims on the respective entities’ balance sheets assuming a hypothetical liquidation at the end of that reporting period when compared with their claims on the respective entities’ balance sheets assuming a hypothetical liquidation at the beginning of that reporting period, after removing any contributions or distributions. Common Partnership Interests on the Operating Partnership’s Consolidated Balance Sheets The common units held by the Company and the noncontrolling common units held by the common limited partners are both presented in the permanent equity section of the Operating Partnership’s consolidated balance sheets in partners’ capital. The redemption rights of the noncontrolling common units permit us to settle the redemption obligation in either cash or shares of the Company’s common stock at our option (see Note 11 “Noncontrolling Interests on the Company’s Consolidated Financial Statements” for additional information). Noncontrolling Interests on the Operating Partnership’s Consolidated Financial Statements Noncontrolling interests in the Operating Partnership’s consolidated financial statements include the noncontrolling interest in property partnerships (see Note 12 “Noncontrolling Interests on the Operating Partnership’s Consolidated Financial Statements”) and the Company’s 1.0% general partnership interest in the Finance Partnership. The 1.0% general partnership interest in the Finance Partnership noncontrolling interest is presented in the permanent equity section of the Operating Partnership’s consolidated balance sheets given that these interests are not convertible or redeemable into any other ownership interest of the Company or the Operating Partnership. |
Equity Offerings | Equity Offerings Underwriting commissions and offering costs incurred in connection with common equity offerings and our at-the-market stock offering program (see Note 13 “Stockholders’ Equity of the Company”) are reflected as a reduction of additional paid-in capital. Issuance costs incurred in connection with preferred equity offerings are reflected as a reduction of the carrying value of the preferred equity. Sales of our common stock under forward equity sale agreements (such as those under the forward equity offering executed in August 2018 and discussed at Note 13) meet the derivatives and hedging guidance scope exception to be accounted for as equity instruments based on the following assessment: (i) none of the agreements’ exercise contingencies were based on observable markets or indices besides those related to the market for our own stock price and operations; and (ii) none of the settlement provisions precluded the agreements from being indexed to our own stock. The net proceeds from any equity offering of the Company are generally contributed to the Operating Partnership in exchange for a number of common units equivalent to the number of shares of common stock issued and are reflected in the Operating Partnership’s consolidated financial statements as an increase in partners’ capital. |
Share-based Incentive Compensation Accounting | Share-based Incentive Compensation Accounting Compensation cost for all share-based awards, including options, requires measurement at estimated fair value on the grant date. Compensation cost is recognized on a straight-line basis over the service vesting period, which represents the requisite service period. The grant date fair value of market measure-based share-based compensation plans are calculated using a Monte Carlo simulation pricing model. The grant date fair value of stock option grants is calculated using the Black-Scholes valuation model. Equity awards settled in cash are valued at the fair value of our common stock on the period end date through the settlement date. Equity awards settled in cash are remeasured at each reporting period and are recognized as a liability in the consolidated balance sheet during the vesting period until settlement. Forfeitures of all share-based awards are recognized when they occur. For share-based awards in which the performance period precedes the grant date, we recognize compensation cost over the requisite service period, which includes both the performance and service vesting periods, using the accelerated attribution expense method. The requisite service period begins on the date the Executive Compensation Committee authorizes the award and adopts any relevant performance measures. For share-based awards with performance-based measures, the total estimated compensation cost is based on our most recent estimate of the probable achievement of the pre-established specific corporate performance measures. These estimates are based on actual results and our latest internal forecasts for each performance measure. For share-based awards with market measures, the total estimated compensation cost is based on the fair value of the award at the grant date. For share-based awards with performance-based measures and market measures, the total estimated compensation cost is based on the fair value per share at the grant date multiplied by our most recent estimate of the number of shares to be earned based on actual results and the probable achievement of the pre-established corporate performance measures based on our latest internal forecasts. In accordance with the provisions of our share-based incentive compensation plan, we accept the return of shares of Company common stock, at the current quoted market price, from employees to satisfy minimum statutory tax-withholding requirements related to shares that vested during the period. For share-based awards granted by the Company, the Operating Partnership issues a number of common units equal to the number of shares of common stock ultimately granted by the Company in respect of such awards. |
Basic and Diluted Net Income Available to Common Stockholders/ Unitholders per Share/ Unit | Basic and Diluted Net Income Available to Common Stockholders per Share Basic net income available to common stockholders per share is computed by dividing net income available to common stockholders, after preferred distributions and the allocation of income to participating securities, by the weighted-average number of shares of common stock outstanding for the period. Diluted net income available to common stockholders per share is computed by dividing net income available for common stockholders, after preferred distributions and the allocation of income to participating securities, by the sum of the weighted-average number of shares of common stock outstanding for the period plus the assumed exercise of all dilutive securities. The impact of the outstanding common units is considered in the calculation of diluted net income available to common stockholders per share. The common units are not reflected in the diluted net income available to common stockholders per share calculation because the exchange of common units into common stock is on a one for one basis, and the common units are allocated net income on a per share basis equal to the common stock (see Note 21 “Net Income Available to Common Stockholders Per Share of the Company”). Accordingly, any exchange would not have any effect on diluted net income (loss) available to common stockholders per share. Nonvested share-based payment awards (including nonvested restricted stock units (“RSUs”), vested market-measure RSUs and vested dividend equivalents issued to holders of RSUs) containing nonforfeitable rights to dividends or dividend equivalents are accounted for as participating securities and included in the computation of basic and diluted net income available to common stockholders per share pursuant to the two-class method. The dilutive effect of shares issuable under executed forward equity sale agreements and stock options are reflected in the weighted average diluted outstanding shares calculation by application of the treasury stock method. The dilutive effect of the outstanding nonvested shares of common stock (“nonvested shares”) and RSUs that have not yet been granted but are contingently issuable under the share-based compensation programs is reflected in the weighted average diluted shares calculation by application of the treasury stock method at the beginning of the quarterly period in which all necessary conditions have been satisfied. Basic and Diluted Net Income Available to Common Unitholders per Unit Basic net income available to common unitholders per unit is computed by dividing net income available to common unitholders, after preferred distributions and the allocation of income to participating securities, by the weighted-average number of vested common units outstanding for the period. Diluted net income available to common unitholders per unit is computed by dividing net income available to common unitholders, after preferred distributions and the allocation of income to participating securities, by the sum of the weighted-average number of common units outstanding for the period plus the assumed exercise of all dilutive securities. The dilutive effect of stock options, outstanding nonvested shares, RSUs, awards containing nonforfeitable rights to dividend equivalents and shares issuable under executed forward equity sale agreements are reflected in diluted net income available to common unitholders per unit in the same manner as noted above for net income available to common stockholders per share. |
Fair Value Measurements | Fair Value Measurements The fair values of our financial assets and liabilities are disclosed in Note 19, “Fair Value Measurements and Disclosures,” to our consolidated financial statements. The only financial assets recorded at fair value on a recurring basis in our consolidated financial statements are our marketable securities. We elected not to apply the fair value option for any of our eligible financial instruments or other items. We determine the estimated fair value of financial assets and liabilities utilizing a hierarchy of valuation techniques based on whether the inputs to a fair value measurement are considered to be observable or unobservable in a marketplace. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. This hierarchy requires the use of observable market data when available. The following is the fair value hierarchy: • Level 1 – quoted prices for identical instruments in active markets; • 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 – fair value measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. We determine the fair value for the marketable securities using quoted prices in active markets for identical assets. Our other financial instruments, which are only disclosed at fair value, are comprised of secured debt, unsecured senior notes, unsecured line of credit and unsecured term loan facility. We generally determine the fair value of our secured debt, unsecured debt, and unsecured line of credit by performing discounted cash flow analyses using an appropriate market discount rate. We calculate the market rate by obtaining period-end treasury rates for maturities that correspond to the maturities of our fixed-rate debt and then adding an appropriate credit spread based on information obtained from third-party financial institutions. These credit spreads take into account factors, including but not limited to, our credit profile, the tenure of the debt, amortization period, whether the debt is secured or unsecured, and the loan-to-value ratio of the debt to the collateral. These calculations are significantly affected by the assumptions used, including the discount rate, credit spreads and estimates of future cash flow. We calculate the market rate of our unsecured line of credit, unsecured term loan facility, and unsecured term loan by obtaining the period-end London Interbank Offered Rate (“LIBOR”) and then adding an appropriate credit spread based on our credit ratings, and the amended terms of our unsecured line of credit, unsecured term loan facility, and unsecured term loan agreement. We determine the fair value of each of our publicly traded unsecured senior notes based on their quoted trading price at the end of the reporting period, if such prices are available. Carrying amounts of our cash and cash equivalents, restricted cash and accounts payable approximate fair value due to their short-term maturities. |
Income Taxes | Income Taxes We have elected to be taxed as a REIT under Sections 856 through 860 of the Code. To qualify as a REIT, we must distribute annually at least 90% of our adjusted taxable income, as defined in the Code, to our stockholders and satisfy certain other organizational and operating requirements. We generally will not be subject to federal income taxes if we distribute 100% of our taxable income for each year to our stockholders. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income taxes (including any applicable alternative minimum tax) on our taxable income at regular corporate rates and we may not be able to qualify as a REIT for four subsequent taxable years. Even if we qualify for taxation as a REIT, we may be subject to certain state and local taxes on our income and property and to federal income taxes and excise taxes on our undistributed taxable income. We believe that we have met all of the REIT distribution and technical requirements for the years ended December 31, 2018 , 2017 and 2016 , and we were not subject to any federal income taxes (see Note 25 “Tax Treatment of Distributions” for additional information). We intend to continue to adhere to these requirements and maintain the Company’s REIT status. Accordingly, no provision for income taxes has been made in the accompanying financial statements. In addition, any taxable income from our taxable REIT subsidiaries, which were formed in 2002 and 2018, are subject to federal, state, and local income taxes. For the years ended December 31, 2018 , 2017 and 2016 the taxable REIT subsidiaries had de minimis taxable income. |
Uncertain Tax Positions | Uncertain Tax Positions We include favorable tax positions in the calculation of tax liabilities if it is more likely than not that our adopted tax position will prevail if challenged by tax authorities. We evaluated the potential impact of identified uncertain tax positions for all tax years still subject to audit under state and federal income tax law and concluded that we did not have any unrecognized tax benefits or any additional tax liabilities as of December 31, 2018 or 2017 . As of December 31, 2018 , the years still subject to audit are 2014 through 2018 under the California state income tax law and 2015 through 2018 under the federal income tax law. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from those estimates. |
Segment | Segments We currently operate in one operating segment, our office properties segment. |
Concentration of Credit Risk | Concentration of Credit Risk All of our properties and development and redevelopment projects are owned and all of our business is currently conducted in the state of California with the exception of the ownership and operation of eight office properties and one development project under construction located in the state of Washington. The ability of tenants to honor the terms of their leases is dependent upon the economic, regulatory, and social factors affecting the communities in which our tenants operate. As of December 31, 2018 , our 15 largest tenants represented approximately 45.7% of total annualized base rental revenues, of which 5.9% was attributable to our largest tenant. We have deposited cash with financial institutions that is insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 per institution. As of December 31, 2018 and 2017 , we had cash accounts in excess of FDIC insured limits. |
Recent Accounting Pronouncements | Accounting Pronouncements Adopted January 1, 2019 ASU No. 2016-02 “Leases (Topic 842)” On February 25, 2016, the FASB issued ASU No. 2016-02 “Leases (Topic 842)” (“ASU 2016-02”) to amend the accounting guidance for leases. The accounting applied by a lessor is largely unchanged under ASU 2016-02. However, the standard requires lessees to recognize lease assets and lease liabilities for leases classified as operating leases on the balance sheet. Lessees will recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it will recognize lease expense for such leases generally on a straight-line basis over the lease term. For leases with a term of 12 months or less where we are the lessee, we plan to make this policy election. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018. In July 2018, the FASB issued ASU No. 2018-11 which (1) simplifies transition requirements for both lessees and lessors by adding an option that permits an organization to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented in its financial statements and (2) provides a practical expedient for lessors that permits lessors to make an accounting policy election to not separate nonlease components from the associated lease components, if the following two criteria are met: (1) the timing and pattern of transfer of the lease and nonlease components are the same and (2) the lease component would be classified as an operating lease if accounted for separately. For leases where we are the lessor, we plan to elect the optional transition relief and apply the practical expedients provided by ASU 2018-11. As a result, leases where we are the lessor will be accounted for in a similar method to existing standards with the underlying leased asset being reported and recognized as a real estate asset. In December 2018, the FASB issued ASU 2018-20 which clarifies lessor treatment of sales taxes and other similar taxes collected from lessees, lessor costs paid directly by lessees and recognition of variable payments for contracts with lease and nonlease components. This will result in a gross-up of amounts recorded to tenant reimbursements and property expenses in our consolidated statements of operations related to certain services that, under existing GAAP guidance, were presented on a net basis and such change will not have an impact to net income. ASU 2016-02 also specifies that upon adoption, lessors will no longer be able to capitalize and amortize certain leasing related costs and instead will only be permitted to capitalize and amortize incremental direct leasing costs. As a result, we have concluded that upon the adoption of the standard, we will be required to expense as incurred certain leasing costs we are currently able to capitalize and amortize as deferred leasing costs under existing guidance. This change had a material impact on the Company’s consolidated financial statements upon adoption of the standard on January 1, 2019. The election of the package of practical expedients described above permits us to continue to account for our leases that commenced before January 1, 2019 under the existing lease accounting guidance for the remainder of their lease terms, and to apply the new lease accounting guidance to leases commencing or modified after January 1, 2019. On January 1, 2019, we recognized a cumulative adjustment to distributions in excess of earnings, as required by ASU 2016-02, to write-off lease origination costs that were capitalized in connection with leases that had not commenced before January 1, 2019. These costs were capitalized in accordance with the lease accounting standards existing prior to January 1, 2019, and would not qualify for capitalization under the new lease accounting guidance. This adjustment did not have a material impact to our consolidated financial statements. For leases where we are the lessee, specifically for our four ground leases, the adoption of the standard will significantly change the accounting on our consolidated balance sheets since both existing ground leases and any future ground leases will be required to be recorded on the Company’s consolidated balance sheets as an obligation of the Company. Existing ground leases executed before the January 1, 2019 adoption date will continue to be accounted for as operating leases and the new guidance will not have a material impact on our recognition of ground lease expense or our results of operations. However, we will be required to recognize a right of use asset and a lease liability on our consolidated balance sheets equal to the present value of the minimum lease payments required in accordance with each ground lease. The adoption of this ASU will result in the recognition of operating lease right of use assets and related liabilities of approximately $80 million to $95 million in the aggregate as of January 1, 2019. We do not expect there will be a material impact to our consolidated statements of operations or consolidated cash flows as a result of adoption of this new guidance. In addition, we currently believe that for new ground leases entered into after the adoption date of the new standard, such leases could be required to be accounted for as financing-type leases, resulting in ground lease expense recorded using the effective interest method instead of on a straight-line basis over the term of the lease. This could have a significant impact on our results of operations if we enter into material new ground leases after the date of adoption since ground lease expense calculated using the effective interest method results in an increased amount of ground lease expense in the earlier years of a ground lease as compared to the current straight-line method. Accounting Pronouncements Effective 2020 and Beyond ASU No. 2016-13 “Financial Instruments - Credit Losses (Topic 326)” On June 16, 2016, the FASB issued ASU No. 2016-13 (“ASU 2016-13”) to amend the accounting for credit losses for certain financial instruments. Under the new guidance, an entity recognizes its estimate of expected credit losses as an allowance, which the FASB believes will result in more timely recognition of such losses. In November 2018, the FASB released ASU No. 2018-19 “ Codification Improvements to Topic 326, Financial Instruments - Credit Losses. ” This ASU clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20 “Financial Instruments – Credit Losses.” Instead, impairment of receivables arising from operating leases should be accounted for under Subtopic 842-30 “Leases – Lessor.” ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company does not anticipate that the guidance will have an impact on the consolidated financial statements or notes to the consolidated financial statements. ASU No. 2018-13 “Fair Value Measurement (Topic 820)” On August 28, 2018, the FASB issued ASU No. 2018-13 (“ASU 2018-13”) to amend the disclosure requirements for fair value measurements. The amendments in ASU 2018-13 include new, modified and eliminated disclosure requirements and are the result of a broader disclosure project called FASB Concepts Statement, Conceptual Framework for Financial Reporting - Chapter 8: Notes to Financial Statements , which the Board finalized on August 28, 2018. The Board used the guidance in the Concepts Statement to improve the effectiveness of ASC 820’s disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for any eliminated or modified disclosures. The Company currently anticipates that the guidance will not have a significant impact on the disclosures in the notes to the consolidated financial statements. ASU No. 2018-15 “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)” On August 29, 2018, the FASB issued ASU No. 2018-15 (“ASU 2018-15”) to amend a customer’s accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. ASU 2018-15 can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently evaluating the impact of ASU 2018-15 on the consolidated financial statements and notes to the consolidated financial statements. |
