Recent Accounting Pronouncements	Note 20—Recent accounting pronouncements: Adopted On January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842), which is a comprehensive rewriting of the lease accounting guidance which aims to increase comparability and transparency with regard to lease transactions. The primary change was the recognition of lease assets for the right-of-use of the underlying asset and lease liabilities for the obligation to make payments by lessees on the balance sheet for leases previously classified as operating leases. ASU 2016-02, as amended, also requires increased qualitative disclosure about leases in addition to quantitative disclosures previously required. As permitted, we adopted this ASU prospectively as of January 1, 2019 with no restatement of prior period financial statements. This ASU permits companies to elect certain practical expedients upon adoption, and at adoption we elected the package of practical expedients related to, among other things, lease classification (in which existing leases classified as operating leases under prior GAAP are classified as an operating lease under the new ASU, and existing leases classified as a capital lease under prior GAAP are classified as a finance lease under the new ASU), nonlease components (in which nonlease components associated with a lease and paid by us to the lessor, such as property taxes, insurance and maintenance, are treated as a lease component and considered part of minimum lease rental payments), and short-term leases (in which leases with an original maturity of 12 months or less are excluded from the recognition requirements of the new ASU). Upon adoption of this new ASU, at January 1, 2019 we recognized an aggregate right-of-use operating lease asset of $35.1 million and a corresponding aggregate operating lease liability of $34.5 million (there was no impact to the opening balance of retained earnings at January 1, 2019 as a result of adopting this new ASU). See Notes 1 and 7. Pending Adoption In December 2019, The Financial Accounting Standards Board issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which changes the accounting for certain income tax transactions and reduces complexity in accounting for income taxes in certain areas. The ASU introduces new guidance including providing a policy election for an entity to not allocate consolidated current and deferred tax expense when a member of a consolidated tax return is not subject to income tax in its separate financial statements and is a disregarded entity by the taxing authority; and providing guidance to evaluate whether a step-up in tax basis of goodwill relates to a business combination in which book goodwill was recognized or a separate transaction. The ASU also changes existing guidance in a number of areas, including: the method of making an intraperiod allocation of total income tax expense if there is a loss in continuing operations and gains outside of continuing operations; determining when a deferred tax liability is recognized after an investor in a non-U.S. entity transitions to or from the equity method of accounting; accounting for tax law changes and year-to-date losses in interim periods; and determining how to apply the income tax guidance to franchise taxes that are partially based on income. The amendments in ASU 2019-12 are effective for us beginning in the first quarter of 2021, with early adoption permitted. We expect to adopt this ASU in the first quarter of 2020 and we do not expect the adoption to have a material effect on our Consolidated Financial Statements.

Note 20—Recent accounting pronouncements:

Adopted

On January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842), which is a comprehensive rewriting of the lease accounting guidance which aims to increase comparability and transparency with regard to lease transactions. The primary change was the recognition of lease assets for the right-of-use of the underlying asset and lease liabilities for the obligation to make payments by lessees on the balance sheet for leases previously classified as operating leases. ASU 2016-02, as amended, also requires increased qualitative disclosure about leases in addition to quantitative disclosures previously required. As permitted, we adopted this ASU prospectively as of January 1, 2019 with no restatement of prior period financial statements. This ASU permits companies to elect certain practical expedients upon adoption, and at adoption we elected the package of practical expedients related to, among other things, lease classification (in which existing leases classified as operating leases under prior GAAP are classified as an operating lease under the new ASU, and existing leases classified as a capital lease under prior GAAP are classified as a finance lease under the new ASU), nonlease components (in which nonlease components associated with a lease and paid by us to the lessor, such as property taxes, insurance and maintenance, are treated as a lease component and considered part of minimum lease rental payments), and short-term leases (in which leases with an original maturity of 12 months or less are excluded from the recognition requirements of the new ASU).
