The amendments to estimating expected credit losses (ASU 2016-13), in particular, how a company considers recoveries and extension options when estimating expected credit losses, are the most relevant to the Corporation. The ASU clarifies that (1) the estimate of expected credit losses should include expected recoveries of financial assets, including recoveries of amounts expected to be written off and those previously written off, and (2) that contractual extension or renewal options that are not unconditionally cancellable by the lender are considered when determining the contractual term over which expected credit losses are measured.
