a liquidity position of at least 8% of total assets. A portion of the Bank’s deposit base has been historically seasonal in nature, with balances typically declining in the winter months through late spring, during which period the Bank’s liquidity position tightens.
Our liquidity position remains strong. During the quarter we initiated pandemic-specific liquidity stress tests to analyze potential impacts from payment deferrals, unanticipated use of committed lines of credit, as well as the possibility of required servicer advances on sold loans. At March 31, 2022, available same-day liquidity totaled approximately $1.1 billion, including cash, borrowing capacity at FHLB and the Federal Reserve Discount Window and various lines of credit. Additional sources of liquidity include cash flows from operations, wholesale deposits, cash flow from our amortizing securities and loan portfolios. We had unused borrowing capacity at the FHLB of $436 million, unused borrowing capacity at the Federal Reserve of $87 million and unused lines of credit totaling $51.0 million, in addition to over $200.0 million in unencumbered, liquid investment portfolio assets.
The Bank maintains a liquidity contingency plan approved by the Bank’s Board of Directors. This plan addresses the steps that would be taken in the event of a liquidity crisis, and identifies other sources of liquidity available to us. Our management believes the level of liquidity is sufficient to meet current and future funding requirements. However, changes in economic conditions, including consumer savings habits and availability or access to the brokered deposit market could potentially have a significant impact on our liquidity position.
Capital Resources
Please see the “Equity” section of the Comparison of Financial Condition for a discussion of shareholders’ equity together with the Note 6 Capital Ratios and Shareholders’ Equity in the consolidated financial statements. Additional information about regulatory capital is contained in the notes to the consolidated financial statements and in our most recent Annual Report on Form 10-K.
Our principal cash requirement is the payment of dividends on our common stock, as and when declared by our Board of Directors. Dividends to shareholders in the aggregate amount of $3.6 million and $3.3 million for the three months ended March 31, 2022 and 2021, respectively. All dividends declared and distributed by us will be in compliance with applicable state corporate law and regulatory requirements.
Off-Balance Sheet Arrangements
We are, from time to time, a party to certain off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on the our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources, that may be material to investors.
Our off-balance sheet arrangements are limited to standby letters of credit whereby the Bank guarantees the obligations or performance of certain customers. These letters of credit are sometimes issued in support of third-party debt. The risk involved in issuing standby letters of credit is essentially the same as the credit risk involved in extending loan facilities to customers, and they are subject to the same origination, portfolio maintenance and management procedures in effect to monitor other credit products. The amount of collateral obtained, if deemed necessary by the Bank upon issuance of a standby letter of credit, is based upon management's credit evaluation of the customer.
Our off-balance sheet arrangements have not changed materially since previously reported in our Annual Report on Form 10-K for the year ended December 31, 2021.
APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES, AND RECENT ACCOUNTING PRONOUNCEMENTS
Our Consolidated Financial Statements were prepared in accordance with GAAP and follow general practices within the industries in which we operate. The most significant accounting policies we follow are presented in Note 1 to the our Annual Report on Form 10-K for the year ended December 31, 2021. Application of these principles requires us to make estimates, assumptions, and judgments that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Most accounting policies are not considered by management to be critical accounting policies. Several factors are considered in determining whether or not a policy is critical in the preparation of the Consolidated
