Recently Adopted Accounting Pronouncements Date Issued and Topic Date Adopted and Method Description Impact February 2016 Leases January 1, 2019 Effective Date Method The new standard replaces the existing guidance on leases and requires the lessee to recognize a right-of-use ("ROU") asset and a lease liability for all leases with lease terms equal to or greater than twelve months. For finance leases, the lessee recognizes interest expense and amortization of the ROU asset, and for operating leases, the lessee recognizes total lease expense on a straight-line basis. The standard offers several practical expedients for transition and certain expedients specific to lessees or lessors. The standard allows for two methods of adoption: retrospective to each prior reporting period presented with the cumulative effect of adoption recognized at the beginning of the earliest period presented or retrospective to the beginning of the period of adoption through a cumulative-effect adjustment (the "Effective Date Method"). See Note 6 for the impact of adoption of this standard. March 2017 Nonrefundable Fees and Other Costs January 1, 2019 Modified Retrospective This update shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. The amendments do not require an accounting change for securities held at a discount. Upon adoption, entities are required to use a modified retrospective transition with the cumulative effect adjustment recognized to retained earnings as of the beginning of the period of adoption. The adoption of this update did not have an impact on our consolidated financial statements.
