Of the $25,145 of cash and cash equivalents at March 31, 2023, $19,311 was located at our foreign subsidiaries and may be subject to withholding tax if repatriated back to the U.S.
During the three months ended March 31, 2023, the increase in cash provided by operating activities is primarily due to increased sales, as well as working capital needs in the prior year period, primarily for inventories due to strategic decisions to secure critical components.
The increase in cash used in investing activities in 2023 relates primarily to the $6,250 cash consideration paid relating to the Spectrum acquisition in the first quarter. Cash used in investing activities in the three months ended March 31, 2023 includes $3,554 for purchases of property and equipment compared to $2,478 during the three months ended March 31, 2022. Capital expenditures are expected to be between $18,000 and $23,000 for the full year 2023.
The decrease in cash provided by financing activities during the three months ended March 31, 2023 is primarily due to increased Amended Revolving Facility borrowings in the first quarter of 2022 to support working capital needs, primarily inventory. Debt payments of $3,116 were made during the three months ended March 31, 2023. At March 31, 2023, we had $228,138 of obligations under the Amended Revolving Facility, excluding deferred financing costs.
The Amended Credit Agreement contains certain financial covenants related to minimum interest coverage, total leverage ratio, and non-material subsidiaries assets to consolidated total assets at the end of each quarter. The Amended Credit Agreement also includes 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. The Amended Credit Agreement contains financial covenants that require that the Company maintain a minimum interest coverage ratio of at least 3.0 to 1.0 at the end of each fiscal quarter. In addition, the Company’s Leverage Ratio at the end of any fiscal quarter shall not be greater than 4.0 to 1.0 ratio (reduced to 3.5:1.0 for quarters ending on or after December 31, 2023); provided that the Company may elect to temporarily increase the Leverage Ratio by 0.5x during the twelve-month period following a material acquisition under the Amended Credit Agreement (“acquisition leverage increase”), subject to certain exceptions. The Company was in compliance with all covenants as of March 31, 2023.
As of March 31, 2023, the unused Amended Revolving Facility was $51,862. The amount available to borrow may be limited by 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 March 31, 2023 and 2022, respectively.
The Company declared dividends of $0.025 per share during each of the three months ended March 31, 2023 and 2022, 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 $5,102 on our sales for the three months ended March 31, 2023. 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
