31, 2020. Other sources of liquidity included the brokered deposit market, deposit listing services, and the ability to offer local time-deposit campaigns. Management is of the opinion that available investments and other potentially liquid assets, along with standby funding sources it has arranged, are more than sufficient to meet the Company’s current and anticipated short-term liquidity needs and that its liquidity has not been adversely impacted by COVID-19.
The Company’s net loans to assets and available investments to assets ratios were 65.4% and 25.1%, respectively, at June 30, 2021, as compared to internal policy guidelines of “less than 78%” and “greater than 3%.” Other liquidity ratios reviewed periodically by Management and the Board include net loans to total deposits and wholesale funding to total assets, including ratios and sub-limits for the various components comprising wholesale funding, which were all well within policy guidelines at June 30, 2021. The Company has been able to maintain a robust liquidity position in recent periods, but no assurance can be provided that our liquidity position will continue at current strong levels.
The holding company’s primary uses of funds include operating expenses incurred in the normal course of business, interest on trust preferred securities, shareholder dividends, and stock repurchases. Its primary source of funds is dividends from the Bank, since the holding company does not conduct regular banking operations. As of June 30, 2021, the holding company maintained a cash balance of $8.7 million. Management anticipates that with the available cash and the continued ability for the Bank to provide dividends to the holding company, that the holding company has sufficient liquidity to meet its funding requirements for the foreseeable future. Both the holding company and the Bank are subject to legal and regulatory limitations on dividend payments, as outlined in Item 5(c) Dividends in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 which was filed with the SEC.
INTEREST RATE RISK MANAGEMENT
Market risk arises from changes in interest rates, exchange rates, commodity prices and equity prices. The Company does not engage in the trading of financial instruments, nor does it have exposure to currency exchange rates. Our market risk exposure is primarily that of interest rate risk, and we have established policies and procedures to monitor and limit our earnings and balance sheet exposure to changes in interest rates. The principal objective of interest rate risk management is to manage the financial components of the Company’s balance sheet in a manner that will optimize the risk/reward equation for earnings and capital under a variety of interest rate scenarios.
To identify areas of potential exposure to interest rate changes, we utilize commercially available modeling software to perform monthly earnings simulations and calculate the Company’s market value of portfolio equity under varying interest rate scenarios. The model imports relevant information for the Company’s financial instruments and incorporates Management’s assumptions on pricing, duration, and optionality for anticipated new volumes. Various rate scenarios consisting of key rate and yield curve projections are then applied in order to calculate the expected effect of a given interest rate change on interest income, interest expense, and the value of the Company’s financial instruments. The rate projections can be shocked (an immediate and parallel change in all base rates, up or down), ramped (an incremental increase or decrease in rates over a specified time period), economic (based on current trends and econometric models) or stable (unchanged from current actual levels).
In addition to a stable rate scenario, which presumes that there are no changes in interest rates, we typically use at least eight other interest rate scenarios in conducting our rolling 12-month net interest income simulations: upward shocks of 100, 200, 300, and 400 basis points, and downward shocks of 100, 200, and 300 basis points. Those scenarios may be supplemented, reduced in number, or otherwise adjusted as determined by Management to provide the most meaningful simulations considering economic conditions and expectations at the time. Given the current near zero interest rate environment it is unlikely that rates could decline much further beyond the downward shock of 100 basis points, therefore the downward shock scenarios of 200,300, and 400 basis points are temporarily being suspended after concurrence by the Company’s Board of Directors. Pursuant to policy guidelines, we generally attempt to limit the projected decline in net interest income relative to the stable rate scenario to no more than 5% for a 100 basis point (bp) interest rate shock, 10% for a 200 bp shock, 15% for a 300 bp shock, and 20% for a 400 bp shock.
