New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	2. RECENT ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Pronouncements Effective January 1, 2019, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-02, Leases (“Topic 842”). This update amends the accounting requirements for leases by requiring recognition of lease liabilities and related right-of-use assets on the balance sheet. Lessees are required to recognize a lease liability measured on a discounted basis, which is the lessee’s obligation to make lease payments arising from a lease, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. We adopted Topic 842 using the modified retrospective approach as of the effective date, January 1, 2019. We have recorded the cumulative effects on our balance sheet as of the effective date. No adjustments were made to prior comparative periods. Due to the number of leases we are party to, the related obligations and right-of-use assets did have a material impact on our unaudited consolidated balance sheets (see Note 11 – Leases). As a result of the adoption, there was no impact on net income or net assets. We recorded operating lease right-of-use assets of $84.0 million, current lease liability of $22.4 million and non-current lease liability of $85.3 million as of March 31, 2019. The right-of-use asset balance reflects the impact of other liability amounts, specifically deferred rent that has been effectively reclassified. As part of the adoption, we elected the package of practical expedients permitted under the transition guidance within Topic 842, which among other things, allowed us to carry forward the historical lease classification. Further, we also applied the practical expedient to combine, when applicable, lease and non-lease components. Leases with a term of 12 months or less are not recorded on the balance sheet. On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (“Topic 606”). As a result of the adoption, we recorded a net increase to retained earnings as of January 1, 2018 of $0.2 million, net of tax, with the impact primarily relating to certain contracts that include event-based variable consideration. For further discussion about our revenue recognition policy see Note 4 – Revenue Recognition. On January 1, 2018, we adopted ASU 2016-15, Statement of Cash Flow (“Topic 230”). This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The update provided new guidance regarding the classification of debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitized transactions, and separately identifiable cash flows and application of the predominance principle. We determined that the manner in which we previously classified our contingent acquisition liability payments in the unaudited consolidated statement of cash flows would change. Based on our evaluation, adoption of this standard required a reclassification of a portion of the payments previously reported as financing activities for comparative periods in the statement of cash flows within our unaudited consolidated financial statements issued for periods beginning on or after January 1, 2018. Under this guidance, portions of these payments have been reclassified from financing activities to operating activities. We applied this change retrospectively, and it did not have a material impact on our unaudited consolidated financial statements. On January 1, 2018, we adopted ASU 2017-01, Business Combinations: Clarifying the Definition of a Business (“Topic 805”), which provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. We applied this change prospectively, and it did not have a material impact on our unaudited consolidated financial statements.
