Proactive Strategic Initiatives Funding Beginning in the 4th quarter of 2022, we proactively began utilizing brokered time deposits to secure fixed cost funding and reduce higher cost short-term borrowings. We held $31.3 million of cash and cash equivalents at March 31, 2023 and maintained $899.3 million of available funding from Federal Home Loan Bank advances, the Federal Reserve's Bank Term Funding Program ("BTFP"), and unsecured lines of credit with correspondent banks. Although we do not plan to utilize the BTFP, our borrowing capacity under the BTFP is $185.6 million based on the value of unpledged securities available to be used as collateral, valued at par value as permitted under the program. Cash and cash equivalents and available funding represented 136% of uninsured deposits at March 31, 2023. Our Assured Checking product provides FDIC deposit insurance protection on up to $100 million. Expense Control and Efficiency Despite inflationary pressures, we reduced core noninterest expense in the first quarter of 2023 compared to the third and the fourth quarters of 2022. Since the beginning of 2020, we have been proactive in our branch network strategy and have closed six branch locations, sold two branch locations and sold three tracts of land that were being held for future branch locations. The optimization of our branch footprint will continue to result in cost savings and allow us to focus more on our core markets. Credit Resolution and Balance Sheet Positioning ☐ Nonaccrual Loans have declined by $27.2 million to $5.6 million since the 3rd quarter of 2021. Incremental resolution of the impaired loan relationship impacted by Hurricane Ida in the 3rd quarter of 2021 is expected to continue throughout 2023. Nonperforming assets to total assets was 0.23% at March 31, 2023 compared to 0.44% at December 31, 2022. ■ We adopted the current expected credit loss accounting standard on January 1, 2023. Allowance for credit losses to total loans increased to 1.45% at March 31, 2023 compared to 1.16% at December 31, 2022. Allowance for credit losses to nonperforming loans increased to 535.6% at March 31, 2023 compared to 214.9% at December 31, 2022. " Over the last two years, we have increased our focus on underwriting high quality credits that are less susceptible to effects from a potential economic downturn and proactively exited credit relationships that do not fit this strategy.
