other covenants and restrictions, including limits on the amount of additional indebtedness, and restrictions on the ability to merge, consolidate or sell all, or substantially all, of our assets. Under the provisions of the Amended Credit Agreement, we may elect to increase our Leverage Ratio to a 4.0 to 1.0 ratio (a “Leverage Increase”) during the fiscal quarter in which a Material Acquisition (as defined in the Amended Credit Agreement) takes place and for the next three fiscal quarters. If the Material Acquisition occurs within the last 45 days of any fiscal quarter, the Leverage Increase is applicable for the following four fiscal quarters. We qualified for and elected the Leverage Increase as a result of the Spectrum Controls acquisition in the fourth quarter of 2021. We were in compliance with all covenants at June 30, 2022.
As of June 30, 2022, the unused Amended Revolving Facility was $4,944. The amount available to borrow may be lower and may vary from period to period based upon our debt and EBITDA levels, which impacts our covenant calculations. The Amended Credit Agreement matures in February 2025.
There were no borrowings under the China Facility during the three months ended June 30, 2022 and 2021, respectively.
The Company declared dividends of $0.050 and $0.045 per share during the six months ended June 30, 2022 and 2021, respectively. The Company’s working capital, capital expenditure and dividend requirements are expected to be funded from cash provided by operations and amounts available under the Amended Credit Agreement.
Although there is ongoing uncertainty related to the current conflict in Ukraine and the continued impact of COVID-19 and variants on our future results, we believe our diverse markets, our strong market position in many of our businesses, and the steps we have taken to strengthen our balance sheet leaves us well-positioned to manage our business through the crisis as it continues to unfold. We continually assess our liquidity and cash positions and have assessed the impact of COVID-19 on our Company. Based on our analysis, we believe our existing balances of cash, the flexibility of our Amended Credit Agreement and our currently anticipated operating cash flows will be more than sufficient to meet our cash needs arising in the ordinary course of business for the next twelve months.
Item 3. Qualitative and Quantitative Disclosures about Market Risk
Foreign Currency
We have international operations in The Netherlands, Sweden, Germany, China, Portugal, Canada, Czech Republic, Mexico, the United Kingdom and New Zealand which expose us to foreign currency exchange rate fluctuations due to transactions denominated in Euros, Swedish Krona, Chinese Renminbi, Canadian dollar, Czech Krona, Mexican pesos, British Pound Sterling, and New Zealand dollar, respectively. We continuously evaluate our foreign currency risk and we take action from time to time in order to best mitigate these risks. A hypothetical 10% change in the value of the U.S. dollar in relation to our most significant foreign currency exposures would have had an impact of approximately $4,013 on our sales for the three months ended June 30, 2022 and $8,253 on our sales for the six months ended June 30, 2022. This amount is not indicative of the hypothetical net earnings impact due to partially offsetting impacts on cost of sales and operating expenses in those currencies. We estimate that foreign currency exchange rate fluctuations during the three months ended June 30, 2022 increased revenues in comparison to the quarter ended June 30, 2021 by $5,174. For the six months ended June 30, 2022, we estimate that foreign currency exchange rate fluctuations increased revenues $8,403 in 2022 compared to 2021.
We translate all assets and liabilities of our foreign operations, where the U.S. dollar is not the functional currency, at the period-end exchange rate and translate sales and expenses at the average exchange rates in effect during the period. The net effect of these translation adjustments is recorded in the condensed consolidated financial statements as comprehensive (loss) income. The translation adjustment was a loss of $8,699 and a gain of $955 for the three months ended June 30, 2022 and 2021, respectively. The translation adjustment was a loss of $9,932 and $3,052 for the six months ended June 30, 2022 and 2021, respectively. Translation adjustments are not adjusted for income taxes as they relate to permanent investments in our foreign subsidiaries. A hypothetical 10% change in the value of the U.S. dollar in relation to our most significant foreign currency net assets would have had an impact of approximately $11,152 on our foreign net assets as of June 30, 2022.
We have contracts to hedge our short-term balance sheet exposure, primarily intercompany, that are denominated in currencies (Euro, Mexican Peso, New Zealand Dollar, Chinese Renminbi, Swedish Krona) other than the subsidiary’s functional currency and are adjusted to current values using period-end exchange rates. The resulting gains or losses are recorded in other (income) expense, net in the consolidated statements of income and comprehensive (loss) income. To minimize foreign currency exposure, the Company had foreign currency contracts with notional amounts of $16,000 at June 30, 2022. The foreign currency contracts are recorded in the
