Actual results could differ from those estimates. Estimates that could change significantly relate to the provision for credit losses and the related allowance, potential impairment of goodwill or other intangible assets, valuation of investment securities and the determination of whether available-for-sale debt securities with fair values less than amortized costs are impaired and require an allowance for credit losses, valuation of other real estate owned, valuation of share based compensation, the assessment that a liability should be recognized with respect to any matters under litigation, the calculation of current and deferred income taxes, and the actuarial projections related to pension expense and the related liability.</span></div>

The new standard is a result of LIBOR likely being discontinued as an available benchmark rate. The standard is elective and provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, or other transactions that reference LIBOR, or another reference rate expected to be discontinued. The amendments in the update are effective for all entities between March 12, 2020 and December 31, 2022. The Company has established a cross-functional working group to guide the Company’s transition from LIBOR and has begun efforts to transition to alternative rates consistent with industry timelines. The Company has identified its products that utilize LIBOR and has implemented enhanced fallback language to facilitate the transition to alternative reference rates. The Company is evaluating existing platforms and systems and preparing to offer new rates.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In December 2019, FASB released ASU 2019-12 - </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Income Taxes (Topic 740),</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> which simplifies the accounting for income taxes by removing multiple exceptions to the general principals in Topic 740.
