Our most liquid assets are cash and due from banks. The levels of these assets are dependent on our operating, financing, lending and investing activities during any given period. At September 30, 2024 and December 31, 2023, cash and due from banks totaled $160.9 million and $147.4 million, respectively. Securities classified as available-for-sale, which provide additional sources of liquidity, totaled $469.5 million at September 30, 2024 and $489.9 million at December 31, 2023.
Certificates of deposit due within one year of September 30, 2024 totaled $137.8 million, or 96.5% of total certificates of deposit. The largest concentration of certificates of deposit represented brokered deposits in the amount of $100.0 million for diversified funding purposes.
We participate in IntraFi Network, allowing us to provide access to multi-million-dollar FDIC deposit insurance protection on deposits for customers, businesses and public entities. We can elect to sell or repurchase this funding as reciprocal deposits from other IntraFi Network banks depending on our funding needs. At September 30, 2024, we had a total of $102.5 million of IntraFi Network deposits, all of which were repurchased as reciprocal deposits from the IntraFi Network.
Although customer deposits remain our preferred source of funds, maintaining back up sources of liquidity is part of our prudent liquidity risk management practices. We have the ability to borrow from the Federal Home Loan Bank of New York and the Federal Reserve Bank of New York (“FRB”) as well as other correspondent banks. At September 30, 2024, we had a total capacity of $577.6 million at the Federal Home Loan Bank of New York, of which $76.0 million was used to collateralize municipal deposits, and $10.0 million was utilized for long-term advances. At September 30, 2024, we also had a $4.5 million collateralized line of credit from the Federal Reserve Bank of New York discount window with no outstanding balance. Additionally, we utilized $50 million of funding through the Bank Term Funding Program from the FRB under a one-year facility expiring in March 2025. We also had a total of $20.0 million of discretionary lines of credit at September 30, 2024 with no outstanding balance. We have a borrowing agreement with Atlantic Community Bankers Bank (“ACBB”) to provide short-term borrowings of $5.0 million at September 30, 2024. There were no outstanding borrowings with ACBB at September 30, 2024.
Our cash flows are comprised of three primary classifications: cash flows from operating activities, investing activities, and financing activities. Net cash provided by operating activities was $21.8 million and $28.5 million for the nine months ended September 30, 2024 and 2023, respectively. Net cash used in investing activities, which consists primarily of disbursements for loan originations and the purchase of securities, offset by principal collections on loans, proceeds from the sale of securities and proceeds from maturing securities and pay downs on securities, was $12.6 million and $106.7 million for the nine months ended September 30, 2024 and 2023, respectively. Net cash provided by financing activities, consisting of activity in deposit accounts and borrowings, was $4.4 million and $150.8 million for the nine months ended September 30, 2024 and 2023, respectively.
We remain committed to maintaining a strong liquidity position. We monitor and evaluate our liquidity position daily. We anticipate that we will have sufficient funds to meet our current funding commitments. Based on our deposit growth and retention, current pricing strategy and regulatory restrictions, we have the ability to retain and increase a substantial portion of maturing time deposits, and we can supplement our funding with borrowings in the event that we allow these deposits to run off at maturity.
Capital Resources. We are subject to various regulatory capital requirements administered by the FRB and the NYSDFS. At September 30, 2024 and December 31, 2023, we exceeded all applicable regulatory capital requirements, and were considered “well capitalized” under regulatory guidelines. See Note 10 to the Notes to the Unaudited Consolidated Financial Statements appearing elsewhere in this Quarterly Report on Form 10-Q for actual and required capital amounts and ratios at September 30, 2024 and December 31, 2023.
Off-Balance Sheet Arrangements
Off-Balance Sheet Arrangements. We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit, which involve elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. Our exposure to credit loss is represented by the contractual amount of the instruments. We use the same credit policies in making commitments as we do for on-balance sheet instruments.
At September 30, 2024, we had $429.1 million in loan commitments outstanding. We also had $15.5 million in standby letters of credit at September 30, 2024.
