Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for credit losses, the valuations of mortgage servicing rights, derivative financial instruments, debt securities in an unrealized loss position, and goodwill.</span></div>

<div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Derivative Financial Instruments Designated as Hedges</span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company recognizes all derivatives in the consolidated balance sheets at fair value. On the date a derivative contract is entered into, the derivative is designated as a hedge of either a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), or a held for trading instrument (“trading instrument”). The relationships between hedging instruments and hedged items is formally documented, as is the risk management objectives and strategy for undertaking various hedge transactions. Both at the hedge’s inception and on an ongoing basis, determination is made as to whether the derivatives that are used in hedging transactions are effective in offsetting changes in cash flows or fair values of hedged items. Changes in fair value of a derivative that is effective and that qualifies as a cash flow hedge are recorded in OCI and are reclassified into earnings when the forecasted transaction or related cash flows affect earnings. Changes in fair value of a derivative that qualifies as a fair value hedge and the change in fair value of the hedged item are both recorded in earnings and offset each other when the transaction is effective. Those derivatives that are classified as trading instruments, including customer loan swaps, are recorded at fair value with changes in fair value recorded in earnings. Hedge accounting is discontinued when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, that it is unlikely that the forecasted transaction will occur, or that the designation of the derivative as a hedging instrument is no longer appropriate.</span></div>

On the date a derivative contract is entered into, the derivative is designated as a hedge of either a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), or a held for trading instrument (“trading instrument”). The relationships between hedging instruments and hedged items is formally documented, as is the risk management objectives and strategy for undertaking various hedge transactions. Both at the hedge’s inception and on an ongoing basis, determination is made as to whether the derivatives that are used in hedging transactions are effective in offsetting changes in cash flows or fair values of hedged items. Changes in fair value of a derivative that is effective and that qualifies as a cash flow hedge are recorded in OCI and are reclassified into earnings when the forecasted transaction or related cash flows affect earnings. Changes in fair value of a derivative that qualifies as a fair value hedge and the change in fair value of the hedged item are both recorded in earnings and offset each other when the transaction is effective. Those derivatives that are classified as trading instruments, including customer loan swaps, are recorded at fair value with changes in fair value recorded in earnings. Hedge accounting is discontinued when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, that it is unlikely that the forecasted transaction will occur, or that the designation of the derivative as a hedging instrument is no longer appropriate.</span></div>
