In the table above, "currently under short-term deferral" refers to loans subject to a 90-day payment deferral at December 31, 2021 and "CARES Act modification" refers to loans subject to longer-term modifications that, were it not for the provisions of the CARES Act, which expired on January 1, 2022, would likely have been reported as TDRs.

Non-performing loans totaled $205.9 million or 0.87% of total loans at December 31, 2021, compared to $276.7 million or 1.21% of total loans at September 30, 2021 and $244.5 million or 1.02% of total loans at December 31, 2020.

The following table presents the ACL and related ACL coverage ratios at the dates indicated and net charge-off rates for the years ended December 31, 2021 and 2020 (dollars in thousands):

	ACL		ACL to Total Loans (1)		ACL to Non-Performing Loans		Net Charge-offs to Average Loans
December 31, 2020	$	257,323	1.08	%	105.26	%	0.26	%
September 30, 2021	$	159,615	0.70	%	57.69	%
December 31, 2021	$	126,457	0.53	%	61.41	%	0.29	%

(1)    ACL to total loans, excluding government insured residential loans, PPP loans and MWL, which carry nominal or no reserves, was 0.62%, 0.81% and 1.26% at December 31, 2021, September 30, 2021 and December 31, 2020, respectively.

The ACL at December 31, 2021 represents management's estimate of lifetime expected credit losses given our assessment of historical data, current conditions and a reasonable and supportable economic forecast as of the balance sheet date. The estimate was informed by Moody's economic scenarios published in December 2021, economic information provided by additional sources, information about borrower financial condition and collateral values, data reflecting the impact of recent events on individual borrowers and other relevant information.

For the quarter ended December 31, 2021, the Company recorded a provision for credit losses of $0.2 million, which included a provision of $1.1 million related to funded loans offset by recoveries of provision related to unfunded loan commitments and accrued interest receivable. The decline in the ACL for the quarter ended December 31, 2021 was primarily attributable to charge-offs, the substantial majority of which were previously reserved for.

The following table summarizes the activity in the ACL for the periods indicated (in thousands):

	Three Months Ended December 31,				Years Ended December 31,

Net interest income

Net interest income for the quarter ended December 31, 2021 was $206.0 million compared to $195.1 million for the immediately preceding quarter ended September 30, 2021 and $193.4 million for the quarter ended December 31, 2020. Interest income increased by $3.5 million for the quarter ended December 31, 2021 compared to the immediately preceding quarter, and decreased by $13.2 million compared to the quarter ended December 31, 2020. Interest expense decreased by $7.4 million compared to the immediately preceding quarter and by $25.9 million compared to the quarter ended December 31, 2020.

The Company’s net interest margin, calculated on a tax-equivalent basis, increased by 0.11% to 2.44% for the quarter ended December 31, 2021, from 2.33% for the immediately preceding quarter ended September 30, 2021. Factors impacting the net interest margin for the quarter ended December 31, 2021 included:

•The average rate paid on FHLB and FRB advances decreased to 1.86% for the quarter ended December 31, 2021, from 2.35% for the quarter ended September 30, 2021. This decrease resulted from the termination and maturity of higher cost cash flow hedges and related borrowings during the quarter ended December 31, 2021.

•The average rate paid on interest bearing deposits decreased to 0.27% for the quarter ended December 31, 2021, from 0.29% for the quarter ended September 30, 2021. This decline reflected continued initiatives taken to lower rates paid on deposits, including the re-pricing of term deposits, partially offset by the issuance of some callable CDs in anticipation of rising rates.

•The tax-equivalent yield on investment securities increased to 1.54% for the quarter ended December 31, 2021 from 1.49% for the quarter ended September 30, 2021. This increase resulted primarily from slower prepayment speeds on securities purchased at a premium.

4

•The tax-equivalent yield on loans increased to 3.50% for the quarter ended December 31, 2021, from 3.45% for the quarter ended September 30, 2021.

Non-interest income and Non-interest expense

Non-interest income totaled $45.6 million for the quarter ended December 31, 2021 compared to $25.5 million for the immediately preceding quarter ended September 30, 2021 and $35.3 million for the quarter ended December 31, 2020. The main reason for the increase in non-interest income for the quarter ended December 31, 2021 compared to the immediately preceding quarter was an increase in the gain on sale of loans. During the quarter, the Company sold a portfolio of single-family residential loans for a gain of $18.2 million.

Non-interest expense totaled $187.9 million for the quarter ended December 31, 2021 compared to $118.0 million for the immediately preceding quarter ended September 30, 2021 and $123.3 million for the quarter ended December 31, 2020. Non-interest expense totaled $547.6 million and $457.2 million for the year ended December 31, 2021 and 2020, respectively. The following table detailsnotable items that impacted non-interest expense for the quarter ended December 31, 2021 (in thousands):

Discontinuance of cash flow hedges	$	(44,833)
Special employee bonus	(6,809)
Professional fees related to tax settlement	(4,198)
Impairment of operating lease equipment	(2,813)
	$	(58,653)

•Employee compensation and benefits increased by $13.3 million for the quarter ended December 31, 2021 compared to the immediately preceding quarter. The Company paid a special bonus in the fourth quarter to substantially all of its employees, in recognition of their hard work and efforts in the challenging environment we have faced over the past two years. Employees, regardless of their position in the organization, shared equally in the bonus payout, which totaled $6.8 million. Additionally, there was an increase of $4.6 million in variable compensation accruals for both incentives and regular annual discretionary bonuses in the fourth quarter.

•Professional fees increased by $5.7 million for the quarter ended December 31, 2021 compared to the immediately preceding quarter. The increase is primarily a result of $4.2 million related to the tax settlement with the Florida Department of Revenue discussed above.

•A loss on discontinuance of cash flow hedges totaling $44.8 million resulted from the termination of $401 million notional of pay fixed interest rate swaps at a weighted average pay rate of 3.24% during the quarter ended December 31, 2021.

•Depreciation and impairment of operating lease equipment included $2.8 million resulting from impairment charges related to certain sand cars in the operating lease equipment portfolio.

Non-GAAP Financial Measures

ACL to total loans, excluding government insured residential loans, PPP loans and MWL is a non-GAAP financial measure. Management believes this measure is relevant to understanding the adequacy of the ACL coverage, excluding the impact of loans which carry nominal or no reserves. Disclosure of this non-GAAP financial measure also provides a meaningful basis for comparison to other financial institutions. The following table reconciles the non-GAAP financial measurement of ACL to total loans, excluding government insured residential loans, PPP loans and MWL to the comparable GAAP financial measurement of ACL to total loans at the dates indicated (dollars in thousands):

	December 31, 2021			September 30, 2021			December 31, 2020

Tangible book value per common share is a non-GAAP financial measure. Management believes this measure is relevant to understanding the capital position and performance of the Company. Disclosure of this non-GAAP financial measure also provides a meaningful basis for comparison to other financial institutions as it is a metric commonly used in the banking industry. The following table reconciles the non-GAAP financial measurement of tangible book value per common share to the comparable GAAP financial measurement of book value per common share at the dates indicated (in thousands except share and per share data):
