Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
Currency Exchange Rate Risk
Our consolidated financial statements are denominated in, and our principal currency is, the U.S. Dollar. For the year ended December 31, 2021, a portion of our net sales ($370.0 million, representing 34.4% of our aggregate net sales), was attributable to sales that were denominated in foreign currencies. All other international sales were denominated in U.S. Dollars. Our principal market risk relates to changes in the value of the Chinese Yuan Renminbi (CNY) and Euro (EUR) relative to the U.S. Dollar (USD), with limited market risk relating to various other currencies. In general, a strengthening of the U.S. Dollar against CNY has a negative effect on our operating income. Our Euro-denominated expenses associated with our European operations (manufacturing sites, a distribution facility and sales representatives) provide a natural hedge for Euro-denominated revenues. Accordingly, a strengthening of the U.S. Dollar against the Euro will generally have a positive effect on our operating income.
We forecast our net exposure related to sales and expenses denominated in foreign currencies. As of December 31, 2021 and 2020, we had entered into foreign currency forward contracts, which qualified as cash flow hedges, with aggregate notional amounts of $123.0 million and $168.2 million, respectively. We also forecast our net exposure in various receivables and payables to fluctuations in the value of various currencies, and we enter into foreign currency forward contracts to mitigate that exposure. As of December 31, 2021 and 2020, we had entered into foreign currency forward contracts, which were not designated as hedging instruments, related to those balance sheet accounts with aggregate notional amounts of $86.0 million and $74.8 million, respectively.
A sensitivity analysis of changes in the fair value of all currency exchange rate derivative contracts at December 31, 2021 and 2020 indicates that, if the U.S. Dollar strengthened or weakened by 10 percent against all currencies, it would have the following impact on the fair value of these contracts (in thousands):
2021
2020
10% Strengthening
$
3,470
$
2,768
10% Weakening
$
(3,470)
$
(2,768)
Gains or losses on the fair value of derivative contracts would generally be offset by gains and losses on the underlying hedged transaction or net exposure. These offsetting gains and losses are not reflected above. See Note 9 to our consolidated financial statements set forth in Item 8 of this report for additional discussion of our foreign currency forward contracts.
Interest Rate Risk
As discussed in Note 8 to our consolidated financial statements set forth in Item 8 of this report, as of December 31, 2021, we had outstanding borrowings of $243.1 million under the Third Amended Credit Agreement. Accordingly, our earnings and after-tax cash flow are affected by changes in interest rates. On December 23, 2019, we entered into a pay-fixed, receive-variable interest rate swap with Wells Fargo Bank, with a notional amount of $75 million, to fix the one-month LIBOR rate at 1.71% for the period from July 6, 2021 to July 31, 2024. This interest rate swap is intended to reduce our exposure to interest rate fluctuations and was not entered into for speculative purposes. Excluding the amount that is subject to a fixed rate under the interest rate swap and assuming the current level of borrowings remained the same, it is estimated that our interest expense and income before income taxes would change by approximately $1.7 million annually for each one percentage point change in the average interest rate under these borrowings.
Certain of the interest rates applicable to our Third Amended Credit Agreement, and applicable to hedging instruments we have purchased to offset interest rate risk under our Third Amended Credit Agreement, are LIBOR-based. We anticipate replacement rates will be identified, as provided for in our Third Amended Credit Agreement, as LIBOR-based rates become unavailable.
