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 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 office and retail 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 June 30, 2019, 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. 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 June 30, 2019, 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 June 30, 2019, 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.

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.

As of June 30, 2019, 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 June 30, 2019 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.

The accompanying interim financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conjunction with the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying interim financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. However, the results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The interim financial statements for the Company and the Operating Partnership should be read in conjunction with the audited consolidated financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2018.

The Operating Partnership is a variable interest entity (“VIE”) that is consolidated by the Company as the primary beneficiary as the Operating Partnership is a limited partnership in which the common limited partners do not have substantive kick-out or participating rights. At June 30, 2019, the consolidated financial statements of the Company included two VIEs in addition to the Operating Partnership: 100 First LLC and 303 Second LLC. At June 30, 2019, the Operating Partnership was determined to be the primary beneficiary of these two VIEs since the Operating Partnership had the ability to control the activities that most significantly impact each of the VIE’s economic performance. As of June 30, 2019, the two VIEs’ total assets, liabilities and noncontrolling interests included on our consolidated balance sheet were approximately $457.3 million (of which $392.0 million related to real estate held for investment), approximately $30.9 million and approximately $187.0 million, respectively. Revenues,

At December 31, 2018, the consolidated financial statements of the Company and the Operating Partnership included three VIEs in which we were deemed to be the primary beneficiary: 100 First LLC, 303 Second LLC and an entity established during the fourth quarter of 2018 to facilitate a transaction intended to qualify as a like-kind exchange pursuant to Section 1031 of the Code (“Section 1031 Exchange”). In January 2019, the Section 1031 Exchange was successfully completed and the related VIE was terminated. At December 31, 2018, the impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests on our consolidated balance sheet by 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.

Effective January 1, 2019, we adopted Financial Accounting Standards Board (“FASB”) ASU No. 2016-02 “Leases (Topic 842)” (“Topic 842”) and the related FASB ASU Nos. 2018-01, 2018-10, 2018-11, 2018-20 and 2019-01 which provide practical expedients, technical corrections and improvements for certain aspects of ASU 2016-02, on a modified retrospective basis. Topic 842 establishes a single comprehensive model for entities to use in accounting for leases and supersedes the existing leasing guidance. We evaluated each of the Company’s contracts to determine if the contract is or contains a lease and concluded that Topic 842 is applicable to the Company as a lessor in its tenant lease agreements and as a lessee in its ground leases.

As a lessor, the Company’s leases with tenants for its real estate assets generally provide for the lease of space, as well as common area maintenance and parking. Under Topic 842, the lease of space is considered a lease component while the common area maintenance billings and tenant parking are considered nonlease components, which fall under revenue recognition guidance in Topic 606. However, upon adopting the guidance in Topic 842, the Company determined that its tenant leases met the criteria to apply the practical expedient provided by ASU 2018-11 to recognize the lease and non-lease components together as one single component. This conclusion was based on the consideration that 1) the timing and pattern of transfer of the nonlease components and associated lease component are the same, and 2) the lease component, if accounted for separately, would be classified as an operating lease. As the lease of space is the predominant component of the Company’s leasing arrangements, we accounted for all lease and non-lease components as one single component under Topic 842. As a result, the adoption of Topic 842 did not have any impact on the Company’s timing or pattern of recognition of rental revenues as compared to previous guidance. Transient daily parking revenue will be accounted for under the guidance in Topic 606 and included in other property income in our consolidated statements of operations.

To reflect their recognition as one lease component, rental revenues, tenant reimbursements and other lease related property income related to leases that also meet the requirements of the practical expedient provided by ASU 2018-11 have been combined in one line item subsequent to the adoption of Topic 842 for the three and six months ended June 30, 2019 in rental income on the Company’s consolidated statements of operations. In addition, under Topic 842, lessor costs for certain services directly reimbursed by tenants, which were previously presented on a net basis under previous guidance, are required to be presented on a gross basis in revenues and expenses. During the three and six months ended June 30, 2019, we incurred additional property expenses of $3.1 million and $6.1 million, respectively, for which we were reimbursed, that were not required to be grossed up under the previous guidance. We presented this amount on a gross basis within rental income and property expenses in the Company’s consolidated statements of operations as a result of the adoption, which had no impact on net income.

Our rental income is mostly comprised of fixed contractual payments defined under the lease that, in most cases, escalate annually over the term of the lease at fixed rates. Additionally, rental income includes variable payments for tenant reimbursements of property-related expenses and payments based on a percentage of tenant’s sales. The table below sets forth the allocation of rental income between fixed and variable payments for the three and six months ended June 30, 2019:

Upon adoption of Topic 842, the Company elected to apply the package of practical expedients provided and did not reassess the following as of January 1, 2019: 1) whether any expired or existing contracts are or contain leases; 2) the lease classification for any expired or existing leases; and 3) initial direct costs for any existing leases. Under Topic 842, initial direct costs for both lessees and lessors would include only those costs that are incremental to the arrangement and would not have been incurred if the lease had not been obtained. As a result, beginning January 1, 2019, the Company will no longer capitalize internal leasing costs and third-party legal leasing costs and instead will expense these costs as incurred. These expenses are included in leasing costs and general and administrative expenses on our consolidated statements of operations in 2019. During the three and six months ended June 30, 2019, the Company expensed approximately $3.4 million and $6.0 million, respectively, of indirect leasing costs which would have been capitalized prior to the adoption of Topic 842.

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 previously 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 $3.1 million cumulative-effect adjustment, primarily related to internal leasing costs and legal leasing costs for tenant leases that had not commenced prior to that date, to increase distributions in excess of earnings for the Company and partners’ capital for the Operating Partnership in connection with our adoption of Topic 842.

Upon the adoption of Topic 842 on January 1, 2019, our determination of the adequacy of the Company’s allowances for tenant receivables includes a binary assessment of whether or not the amounts due under a tenant’s lease agreement are probable of collection. For such amounts that are deemed probable of collection, revenue continues to be recorded on a straight-line basis over the lease term. For such amounts that are deemed not probable of collection, revenue is recorded as the lesser of (i) the amount which would be recognized on a straight-line basis or (ii) cash that has been received from the tenant, with any tenant and deferred rent receivable balances charged as a direct write-off against rental income in the period of the change in the collectability determination. In addition, for tenant and deferred rent receivables deemed probable of collection we also may record an allowance under other authoritative GAAP depending upon our evaluation of the individual receivables, specific credit enhancements, current economic conditions, and other relevant factors. Such allowances are recorded as increases or decreases through rental income on our consolidated statements of operations.

The Company’s ground leases are the primary contracts in which we are the lessee. Upon adoption of Topic 842 on January 1, 2019, the Company had four existing ground leases which were classified as operating leases. We elected to apply the practical expedient to use hindsight in determining the lease term of our existing ground leases. As discussed above, the Company also elected to apply the package of practical expedients provided by Topic 842 and therefore did not reassess the classification of these ground leases. Existing ground leases that commenced before the January 1, 2019 adoption date continued to be accounted for as operating leases, and the new guidance did not have a material impact on our recognition of ground lease expense or our results of operations. However, for periods beginning after January 1, 2019, we are now required to recognize a lease liability on our consolidated balance sheets equal to the present value of the minimum future lease payments required in accordance with each ground lease, as well as a right of use asset equal to the lease liability adjusted for above and below market intangibles and deferred leasing costs. The adoption of Topic 842 resulted in the recognition of right of use ground lease assets totaling $82.9 million and ground lease liabilities totaling $87.4 million on January 1, 2019. There was no material impact to our consolidated statements of operations or consolidated statements of cash flows as a result of adoption of this new guidance. For further information, refer to Note 10.

We recognize revenue from rent, tenant reimbursements, parking and other lease-related 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) payment has been received or the collectability of the amount due is probable. 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. Minimum annual rental revenues are recognized in rental revenues on a straight-line basis over the non-cancellable term of the related lease.

We carry our current and deferred rent receivables net of allowances for amounts that may not be collected. Prior to the adoption of Topic 842 on January 1, 2019, the allowances are increased or decreased through provision for bad debts on our consolidated statements of operations. Upon the adoption of Topic 842 on January 1, 2019, our determination of the adequacy of the Company's allowances for tenant receivables includes a binary assessment of whether or not the amounts due under a tenant’s lease agreement are probable of collection. For such amounts that are deemed probable of collection, revenue continues to be recorded on a straight-line basis over the lease term. For such amounts that are deemed not probable of collection, revenue is recorded as the lesser of (i) the amount which would be recognized on a straight-line basis or (ii) cash that has been received from the tenant, with any tenant and deferred rent receivable balances charged as a direct write-off against rental income in the period of the change in the collectability determination. In addition, for tenant and deferred rent receivables deemed probable of collection we also may record an allowance under other authoritative GAAP depending upon our evaluation of the individual receivables, specific credit enhancements, current economic conditions, and other relevant factors. Such allowances are recorded as increases or decreases through rental income on our consolidated statements of operations. For the three months ended June 30, 2019, we recorded a provision for bad debts of $0.2 million. For the six months ended June 30, 2019, we recorded a net reversal of allowance for tenant and deferred rent receivables of $3.3 million primarily due to the improved credit quality of a tenant that we previously recorded a provision against during the three months ended June 30, 2018. For the three and six months ended June 30, 2018, we recorded a provision for bad debts of $5.6 million and $5.4 million, respectively, primarily related to this tenant.

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 complete and 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 or controls the physical use of the leased 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.

Reimbursements from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs, are recognized in rental income subsequent to the adoption of Topic 842 in the period the recoverable costs are incurred. Tenant reimbursements where we pay the associated costs directly to third-party vendors and are reimbursed by our tenants are recognized and recorded on a gross basis.

Other property income primarily includes amounts recorded in connection with transient daily parking, tenant bankruptcy settlement payments, broken deal income and property damage settlement related payments. Other property income also includes miscellaneous income from tenants, restoration fees and fees for late rental payments. Amounts recorded within other property income fall within the scope of Topic 606 and are accounted for at the point in time when control of the goods or services transfers to the customer and our performance obligation is satisfied.

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 Instrument - 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 a material impact on its consolidated financial statements or notes to its consolidated financial statements.

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 (the “Concepts Statement”), which the FASB finalized on August 28, 2018. The FASB used the guidance in the Concepts Statement to improve the effectiveness of Topic 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 its consolidated financial statements.

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 its consolidated financial statements and notes to its consolidated financial statements.
