In February 2016, FASB issued an ASU that will require lessees to recognize most leases on the balance sheet. This ASU allows lessees to make an accounting policy election to not recognize a lease asset and liability for leases with a term of 12 months or less and do not have a purchase option that is expected to be exercised. For public entities, this ASU is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. This ASU must be applied using the modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is currently evaluating the impact this guidance will have on its financial statements. In June 2016, FASB issued an ASU that changes the impairment model for most financial assets and certain other instruments, and will also require expanded disclosures. For public entities, this ASU is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. The provisions of the ASU must be applied as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is currently evaluating the impact this ASU will have on its financial statements.

This ASU must be applied as of the beginning of the fiscal year of adoption (that is, the initial application date). The amended presentation and disclosure guidance are required only prospectively. The Company is currently evaluating the impact this guidance will have on its financial statements. In February 2018, FASB issued an ASU that provides entities with the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of recent U.S. tax reform to retained earnings. The Company adopted this ASU effective during the third quarter of 2018, and adoption did not have a material impact on its disclosures. In August 2018, FASB issued an ASU that aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with those for capitalizing implementation costs incurred to develop or obtain internal use software.

This ASU must be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption.
