New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted Accounting Pronouncements In May 2017, the Financial Accounting Standards Board ("FASB") issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09"). This ASU provides clarity about which changes to the terms or conditions of a share-based payment award require the application of modification accounting. Specifically, ASU 2017-09 clarifies that changes to the terms or conditions of an award should be accounted for as a modification unless all of the following are met: 1) the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified, 2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified and 3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. ASU 2017-09 is effective for annual reporting periods beginning after December 15, 2017. The Company adopted ASU 2017-09 on January 1, 2018 and does not expect ASU 2017-09 to significantly impact its accounting for share-based payment awards, as changes to awards' terms and conditions subsequent to the grant date are unusual and infrequent in nature. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business ("ASU 2017-01"). This ASU provides clarifying guidance on what constitutes a business acquisition versus an asset acquisition. Specifically, the new guidance lays out a screen to more easily determine if a set of integrated assets and activities does in fact represent a business. Under the ASU 2017-01, when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, the assets do not represent a business. ASU 2017-01 is effective for annual reporting periods beginning after December 15, 2017. The Company adopted ASU 2017-01 on January 1, 2018 with no impact to the Company's accounting treatment of its acquisitions. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, a Consensus of the FASB Emerging Issues Task Force ("ASU 2016-15"). This ASU provides clarifying guidance on the presentation of certain cash receipts and cash payments in the statement of cash flows. ASU 2016-15 is effective for annual reporting periods beginning after December 15, 2017. The Company adopted ASU 2016-15 on January 1, 2018, with no impact to its presentation of cash receipts and payments on its consolidated statements of cash flows. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). This new standard replaces all preceding U.S. GAAP guidance on this topic and eliminates all industry-specific guidance. ASU 2014-09 provides a unified five-step model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. The Company adopted ASU 2014-09 on January 1, 2018 using the modified retrospective approach and recorded a cumulative adjustment to retained earnings of approximately $410,000 at the adoption date. The majority of the Company's revenue recognition policies were not impacted by the new revenue standard, as leases (the source of the Company's majority of revenues) are excluded from ASU 2014-09. Only the accounting treatment for the customer loyalty programs at the TRS properties was impacted by the adoption of ASU 2014-09. See Note 11 to the condensed consolidated financial statements for further details on the adoption impact of ASU 2014-09 at the TRS Properties. Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal Use Software (Subtopic 350-40: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (a consensus of the FASB Emerging Issues Task Force) ("ASU 2018-15"). This ASU clarifies that entities should follow the guidance for capitalizing implementation costs incurred to develop or obtain internal-use software to account for implementation costs of cloud computing arrangements that are service contracts. ASU 2018-15 does not change the accounting for the service component of a cloud computing arrangement. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company does not expect the adoption of ASU 2018-15 to have a significant impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). This ASU simplifies an entity's goodwill impairment test by eliminating Step 2 from the test. The new guidance also amends the definition of impairment to a condition that exists when the carrying amount of goodwill exceeds its fair value. By eliminating Step 2 from the test, entities are no longer required to determine the implied fair value of goodwill by computing the fair value (at impairment testing date) of all assets and liabilities in a manner similar to that required in conjunction with business combinations. Upon the adoption of ASU 2017-04, an impairment charge is simply recorded as the difference between carrying value and fair value, when carrying value exceeds fair value. ASU 2017-04 is effective for annual reporting periods beginning after December 15, 2019 and early adoption is permitted. The Company does not expect the adoption of ASU 2017-04 to significantly impact its goodwill impairment testing. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instrument ("ASU 2016-13"). This ASU introduces a new model for estimating credit losses for certain types of financial instruments, including loans receivable and net investments in direct financing leases, amongst other financial instruments. ASU 2016-13 sets forth an "expected credit loss" impairment model to replace the current "incurred loss" method of recognizing credit losses, which is intended to improve financial reporting by requiring timely recording of credit losses on loans and other financial instruments. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted for fiscal years beginning after December 15, 2018. The Company does not expect the adoption of ASU 2016-13 to have a significant impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). This ASU primarily provides new guidance for lessees on the accounting treatment of operating leases. Under the new guidance, lessees are required to recognize assets and liabilities arising from operating leases on the balance sheet. ASU 2016-02 also aligns lessor accounting with the revenue recognition guidance in Topic 606 of the Accounting Standards Codification. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018 and was originally required to be adopted on a modified retrospective basis, meaning the new leasing model will be applied to the earliest year presented in the financial statements and thereafter. However, in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements ("ASU 2018-11") which permits companies to apply the transition provisions of the lease accounting standard at its effective date (i.e. comparative financial statements would not be required). The Company intends to apply the new transition option under ASU 2018-11 to its adoption of the new leasing standard. The Company is evaluating the impact of adopting this new accounting standard on its financial statements but does not expect the adoption of the new guidance to have a significant impact on the accounting treatment of its triple-net tenant leases, which are the primary source of revenue to the Company. Generally speaking, ASU 2016-02 will more significantly impact the accounting for leases in which GLPI is the lessee by requiring the Company to record a right of use asset and lease liability on its consolidated balance sheets for these leases. Although the Company has made significant strides in the implementation of ASU 2016-02, due to the recent transactions described in Note 1 to the condensed consolidated financial statements, which resulted in the Company's entry into a number of new ground leases and the uncertainty surrounding borrowing rates at January 1, 2019, the Company is still evaluating the final dollar impact of adopting the new leasing standard.
