The decrease primarily related to decreased commission expense and branch manager compensation driven by decreased loan origination volume and branch profitability as gross margins decreased.

•	Professional fees decreased $489,000 to $361,000 during the quarter ended June 30, 2021 compared to $850,000 of expense during the quarter ended June 30, 2020. The decrease related to a decrease in litigation costs compared to the prior year, as the Herrington settlement was resolved in 2020.

•

Other noninterest expense decreased $561,000 to $2.7 million during the quarter ended June 30, 2021 compared to $3.2 million during the quarter ended June 30, 2020. The decrease related to a decrease in the provision for losses on loans sold to the secondary market that results from both early payoff and early default provisions with investors. The decreased provision is driven by both an decrease in the number and volume of loans sold, as well as actual default activity resulting from COVID-19 pandemic was lower than expected.

Recent Developments:

COVID-19 Pandemic and the CARES Act

The CARES Act, signed into law at the end of March 2020, allowed for a temporary delay in the adoption of accounting guidance under Accounting Standards Codification Topic 326, “Financial Instruments – Credit Losses (“CECL”) until the earlier of December 31, 2020 or the 60th day after the end of the COVID-19 national emergency. During the quarter ended March 31, 2020, pursuant to the CARES Act and guidance from the Securities and Exchange Commission (“SEC”) and Financial Accounting Standards Board (“FASB”), we elected to delay adoption of CECL. On December 27, 2020, the Consolidated Appropriations Act, 2021 was signed into law. Among other provisions, this Act extended the temporary delay on the adoption of CECL until January 1, 2022. We have elected to continue to delay adoption of CECL. As a result, our financial statements for the quarter and year ended June 30, 2021 include an allowance for loan losses that was prepared under the existing incurred loss methodology.
