Recently Issued and Adopted Accounting Pronouncements [Abstract]
Recently Issued and Adopted Accounting Pronouncements	NOTE B - Recently Issued and Adopted Accounting Pronouncements Recently Issued Accounting Pronouncements: Changes to U.S. GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). We considered the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations. Leases. In February 2016, the FASB issued ASU 2016-02 which amended various aspects of existing guidance for leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. The main difference between ASU 2016-02 and previous U.S. GAAP is the recognition of lease assets and lease liabilities by lessees on the balance sheet for those leases classified as operating leases under previous U.S. GAAP. As a result, we have recognized a liability representing our lease payments and a right-of-use asset representing our right to use the underlying asset for the lease term on the balance sheet. We adopted the requirements of the new lease standard effective January 1, 2019 using the modified retrospective method and have not restated comparative periods. We elected the transition package of three practical expedients permitted within the standard, which eliminates the requirements to reassess prior conclusions about lease identification, lease classification, and initial direct costs. We did not elect the hindsight practical expedient, which permits the use of hindsight when determining lease term and impairment of right-of-use assets. Further, we elected a short-term lease exception policy, permitting us to not apply the recognition requirements of this standard to short-term leases (i.e. leases with terms of 12 months or less). For our real property leases, we did not elect the accounting policy to account for lease and non-lease components as a single component. As part of the adjustment for ASU 2016-02 effective January 1, 2019, we derecognized certain assets and liabilities associated with legacy build-to-suit arrangements and the deferred gain on previous sale leaseback transactions. Accordingly, $53.5 million of net property and equipment, $50.8 million of financing obligations, $9.3 million of other net liabilities, and $2.3 million of deferred tax assets recorded on the balance sheet as of December 31, 2018 were removed as part of our transition adjustment. Effective January 1, 2019, we recognized right-of-use lease assets totaling $177.9 million and recorded lease liabilities totaling $175.4 million. The net adjustment recorded to equity as of January 1, 2019 was a credit of $6.8 million. Since we are not restating prior periods as part of adopting this guidance, our results in 2019 will not be directly comparable to our results for periods before 2019. Specifically, for those leases that were previously recognized on our balance sheet prior to 2019, their associated depreciation and interest expense will be characterized as rent expense. The adoption of ASU 2016-02 had an immaterial impact on our consolidated statement of income and our consolidated statement of cash flows for the nine-month period ended September 30, 2019.

NOTE B - Recently Issued and Adopted Accounting Pronouncements

Recently Issued Accounting Pronouncements:

Changes to U.S. GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). We considered the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations.

Leases. In February 2016, the FASB issued ASU 2016-02 which amended various aspects of existing guidance for leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. The main difference between ASU 2016-02 and previous U.S. GAAP is the recognition of lease assets and lease liabilities by lessees on the balance sheet for those leases classified as operating leases under previous U.S. GAAP. As a result, we have recognized a liability representing our lease payments and a right-of-use asset representing our right to use the underlying asset for the lease term on the balance sheet. We adopted the requirements of the new lease standard effective January 1, 2019 using the modified retrospective method and have not restated comparative periods.

We elected the transition package of three practical expedients permitted within the standard, which eliminates the requirements to reassess prior conclusions about lease identification, lease classification, and initial direct costs.
