In addition, we had $11.7 million in PPP loans as of September 30, 2021 to attorney customers which are excluded from the table above. We remain focused on prudently growing our Litigation-Related loan portfolio.
Securities. Securities available-for-sale increased $24.0 million, or 20.4%, to $141.7 million at September 30, 2021 from $117.7 million at December 31, 2020, driven by purchases of $70.5 million, offset by paydowns of $43.6 million, unrealized losses of $2.2 million through other comprehensive income, and net amortization of $613 thousand.
Funding. Total deposits increased $173.0 million, or 21.5%, to $977.0 million at September 30, 2021 from $804.1 million at December 31, 2020. We continue to focus on the acquisition and expansion of core deposit relationships, which we define as all deposits except for certificates of deposit. Core deposits totaled $965.9 million at September 30, 2021, or 98.9% of total deposits at that date, compared to $792.9 million or 98.6% of total deposits at December 31, 2020.
In addition to our core deposits as a source of funding, the Company continues to prudently manage its balance sheet through deposit sweep programs, maintaining off-balance sheet funds totaling $443.9 million at September 30, 2021 which is a $63.6 million, or 16.7%, increase from the December 31, 2020 balance of $380.3 million.
At September 30, 2021, we had the ability to borrow a total of $133.8 million from the Federal Home Loan Bank of New York. We also had an available line of credit with the Federal Reserve Bank of New York discount window of $27.5 million. At September 30, 2021, we also had $67.5 million in aggregate unsecured lines of credit with unaffiliated correspondent banks. No amounts were outstanding on any of the aforementioned lines of credit at September 30, 2021.
Equity. Total stockholders’ equity increased $11.1 million, or 8.8%, to $137.2 million at September 30, 2021, from $126.1 million at December 31, 2020.
Asset Quality. Nonperforming assets, totaling $12 thousand, consisted of several nonaccrual consumer loans as of September 30, 2021. As of September 30, 2021, the allowance for loan losses was $8.7 million, or 1.16% of total loans, as compared to $11.4 million, or 1.70% of total loans at December 31, 2020. The decrease in the allowance as a percentage of loans is a result of the charge-off of $9.0 million upon reclassification of the legacy NFL consumer post settlement loan portfolio from held for investment to held for sale as our overall reserve for loan losses to total loans returned to pre-pandemic levels. At September 30, 2021, special mention and substandard loans totaled $24.8 million and $4.8 million, respectively.
