Stakeholders have expressed concerns with the current approach on the basis that current GAAP excludes certain callable debt securities from consideration of early repayment of principal even if the holder is certain that the call will be exercised. As a result, upon the exercise of a call on a callable debt security held at a premium, the unamortized premium is recorded as a loss in earnings. Further, there is diversity in practice (1) in the amortization period for premiums of callable debt securities, and (2) in how the potential for exercise of a call is factored into current impairment assessments. Another issue is that the practice in the United States is to quote, price, and trade callable debt securities assuming a model that incorporates consideration of calls (also referred to as “yield-to-worst” pricing). </font></div><div style="line-height:120%;text-align:left;font-size:8pt;"><font style="font-family:inherit;font-size:8pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;">The ASU shortens the amortization period for certain callable debt securities held at a premium and requires the premium to be amortized to the earliest call date.

This new guidance was issued to address concerns that current generally accepted accounting principles (GAAP) restricts the ability to record credit losses that are expected, but do not yet meet the “probable” threshold by replacing the current “incurred loss” model for recognizing credit losses with an “expected life of loan loss” model referred to as the Current Expected Credit Loss (CECL) model.</font></div><div style="line-height:120%;text-align:left;font-size:8pt;"><font style="font-family:inherit;font-size:8pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;">Under the CECL model, certain financial assets carried at amortized cost, such as loans held for investment and held-to-maturity debt securities, are required to be presented at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the “incurred loss” model required under current GAAP, which delays recognition until it is probable a loss has been incurred. The change could materially affect how the allowance for loan losses is determined and cause a charge to earnings through the provision for loan losses. Such would adversely affect the financial condition of the Corporation. </font></div><div style="line-height:120%;text-align:left;font-size:8pt;"><font style="font-family:inherit;font-size:8pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;">The ASU is effective for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 (i.e., January 1, 2020, for calendar year entities).

The Corporation established an implementation team that meets on a regular basis to oversee activities and monitor progress.
