On June 25, 2022, we had $7.2 million outstanding on our $550 million revolving credit facility, and we had approximately $535.7 million in remaining availability after considering $7.1 million in outstanding letters of credit. Financial covenants on the unsecured revolving credit facility and unsecured notes include minimum interest tests and a maximum leverage ratio. The agreements also restrict the amount of additional indebtedness we may incur and the amount of assets which may be sold. We were in compliance with all our covenant requirements on June 25, 2022.
At the end of the second quarter of 2022, we have approximately $1.2 billion in total liquidity, consisting of our net cash surplus and remaining availability under our revolving credit facility and a shelf agreement with certain lenders providing up to $500 million in borrowing capacity.

CRITICAL ACCOUNTING POLICIES
In preparing our consolidated financial statements, we follow accounting principles generally accepted in the United States. These principles require us to make certain estimates and apply judgments that affect our financial position and results of operations. We continually review our accounting policies and financial information disclosures. There have been no material changes in our policies or estimates since December 25, 2021.
Item 3. Quantitative and Qualitative Disclosures about Market Risk.
We are exposed to market risks related to fluctuations in interest rates on our variable rate debt, which consists of a revolving credit facility and industrial development revenue bonds. We do not currently use interest rate swaps, futures contracts or options on futures, or other types of derivative financial instruments to mitigate this risk.
For fixed rate debt, changes in interest rates generally affect the fair market value, but not earnings or cash flows. Conversely, for variable rate debt, changes in interest rates generally do not influence fair market value, but do affect future earnings and cash flows. We do not have an obligation to prepay fixed rate debt prior to maturity, and as a result, interest rate risk and changes in fair market value should not have a significant impact on such debt until we would be required to refinance it.
We are subject to fluctuations in the price of lumber. We experience significant fluctuations in the cost of commodity lumber products from primary producers (the “Lumber Market”). A variety of factors over which we have no control, including government regulations, transportation, environmental regulations, weather conditions, economic conditions, and natural disasters, impact the cost of lumber products and our selling prices. While we attempt to minimize our risk from severe price fluctuations, substantial, prolonged trends in lumber prices can affect our sales volume, our gross margins, and our profitability. We anticipate that these fluctuations will continue in the future. (See “Impact of the Lumber Market on Our Operating Results.”)
Our international operations have exposure to foreign currency rate risks, primarily due to fluctuations in their local currency, which is their functional currency, compared to the U.S. Dollar. Additionally, certain of our operations enter into transactions that will be settled in a currency other than the U.S. Dollar. We may enter into forward foreign exchange rate contracts in the future to mitigate foreign currency exchange risk. Historically, our hedge contracts are deemed immaterial to the financial statements, however any material hedge contract in the future will be disclosed.
