Cash used in investing activities in the six months ended June 30, 2021 relates entirely to purchases of property and equipment. Purchases of property and equipment were $5,885 during the six months ended June 30, 2021 compared to $3,614 during the six months ended June 30, 2020 reflecting continued commitments to capital expenditure projects supporting customer and growth initiatives. Cash used in investing activities in the prior year period included a $14,728 outflow related to the acquisition of Dynamic Controls. Capital expenditures are expected to be between $12,000 and $15,000 for 2021.
The decrease in cash provided by financing activities in the six months ended June 30, 2021 from the six months ended June 30, 2020 is because the 2020 period included the acquisition of Dynamic Controls for approximately $14,700, net of cash received. At June 30, 2021, we had $112,897 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. We were in compliance with all covenants at June 30, 2021.
As of June 30, 2021, the unused Amended Revolving Facility was $112,103. 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 six months ended June 30, 2021 and 2020, respectively.
The Company declared dividends of $0.045 and $0.040 per share during the six months ended June 30, 2021 and 2020, respectively.
Although there is ongoing uncertainty related to the anticipated impact of COVID-19 and variants on our future results, we believe our diverse markets, and the steps we have taken to strengthen our balance sheet, such as retaining cash to support shorter term needs and extending the maturity of our revolving credit facility in the second quarter of 2020 leaves us well-positioned to manage our business through the crisis as it continues to unfold. We have reviewed numerous potential scenarios in connection with 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 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 foreign operations in The Netherlands, Sweden, Germany, China, Portugal, Czech Republic, Canada, Mexico, the United Kingdom and New Zealand which expose the Company to foreign currency exchange rate fluctuations due to transactions denominated in Euros, Swedish Krona, Chinese Renminbi, Czech Krona, Canadian dollar, Mexican pesos, British Pound Sterling and New Zealand dollar, respectively. We continuously evaluate our foreign currency risk and will 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 $4,000 on our sales for the three months ended June 30, 2021 and $8,500 on our sales for the six months ended June 30, 2021. 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, 2021 increased sales in comparison to the quarter ended June 30, 2020 by $4,104. For the six months ended June 30, 2021, we estimate that foreign currency exchange rate fluctuations increased sales $8,378 in 2021 compared to 2020.
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 income. The translation adjustment was a gain of $955 and $1,932 for the three months ended June 30, 2021 and 2020, respectively. The translation adjustment was a loss of $3,052 and $496 for the six months ended June 30, 2021 and 2020, 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
