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%;padding-bottom:6px;padding-top:6px;text-align:left;padding-left:72px;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.

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%;padding-bottom:12px;padding-top:12px;text-align:left;padding-left:48px;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).

Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers.

The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Corporation plans to adopt this ASU in the first quarter of 2019. The impact of this ASU continues to be evaluated, but it’s expected a one-time adjustment to the Corporation’s other assets and other liabilities on the consolidated balance sheet will occur as of the beginning of the first reporting period in which the new standard is effective. The magnitude of any such adjustment or the overall impact of the new standard on financial condition, results of operations and regulatory capital is being evaluated. </font></div><div style="line-height:120%;text-align:left;padding-left:48px;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;padding-left:24px;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;padding-left:24px;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;font-weight:bold;">FASB Accounting Standards Updates No. 2016-01, </font><font style="font-family:Arial;font-size:8pt;font-style:italic;font-weight:bold;">Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities </font></div><div style="line-height:120%;text-align:left;padding-left:24px;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;padding-left:48px;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;font-weight:bold;">Summary -</font><font style="font-family:Arial;font-size:8pt;"> The FASB has issued Accounting Standards Update (ASU) No. 2016-01, </font><font style="font-family:Arial;font-size:8pt;font-style:italic;">Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.</font><font style="font-family:Arial;font-size:8pt;"> The new guidance is intended to improve the recognition and measurement of financial instruments.

The amendments in this update supersede virtually all existing GAAP revenue recognition guidance, including most industry-specific revenue recognition guidance. ASU 2014-09 creates a single, principle-based revenue recognition framework and will require entities to apply significantly more judgment and expanded disclosures surrounding revenue recognition. The core principle requires an entity to recognize revenue in a manner that depicts the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those good or services. ASU 2014-09 applies to contracts with customers to provide goods and services, with certain exclusion such as lease contracts, financing arrangements and financial instruments. The amendments in ASU 2014-09 are effective for annual reporting periods beginning after December 15, 2017. Early adoption is permitted for annual reporting periods beginning after December 15, 2016. </font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:left;padding-left:48px;font-size:8pt;"><font style="font-family:Arial;font-size:8pt;">The Corporation’s revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. The revenue line items within the scope of this new guidance have been identified and the Corporation's accounting policies will not materially change since the principles of revenue recognition from the ASU are largely consistent with existing guidance and the Corporation's current practices. The Corporation has elected to implement using the modified retrospective application, with the cumulative effect recorded as an adjustment to opening retained earnings at January 1, 2018. Qualitative disclosures of performance obligations related to revenue recognition and disaggregation for significant categories of revenue will be presented according to the scope of the guidance.</font></div></div>
