Under the updated guidance, impairment will now be recognized as the amount by which a reporting unit’s carrying value exceeds its fair value. The standard will be effective for us in the first quarter of 2020 on a prospective basis with early adoption permitted. We do not expect the adoption of this guidance to have a material effect on our financial condition and results of operations.</font></div><div style="line-height:120%;text-align:left;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;font-style:italic;font-weight:bold;">Premium Amortization on Purchased Callable Debt Securities</font></div><div style="line-height:120%;text-align:left;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;">In March 2017, the FASB issued guidance on the amortization period for purchased callable debt securities held at a premium. The guidance requires the premium to be amortized to the earliest call date. Under current guidance, premiums generally are amortized over the contracted life of the security. This guidance is effective for us in the first quarter of 2019 on a modified retrospective basis through a cumulative effect adjustment to beginning retained earnings. Early adoption is permitted. Securities held at a discount do not require an accounting change. We are in the process of evaluating the effect the updated guidance will have on our financial condition and results of operations.</font></div><div style="line-height:120%;text-align:left;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:9.75pt;"><font style="font-family:News Gothic,sans-serif;font-size:9.75pt;">Refer to the 2016 Form 10-K for information on other accounting guidance not yet adopted.</font></div></div>
