Item 7A. Quantitative and Qualitative Disclosures About Market Risk
 
We have no derivative instruments and minimal exposure to commodity market risks. 
 
Foreign Currency Exchange Rates
 
We face exchange rate risk from transactions with customers in countries outside the United States and from intercompany transactions between affiliates. Transactional exchange rate risk arises from the purchase and sale of goods and services in currencies other than our functional currency or the functional currency of the applicable subsidiary. We also face translational exchange rate risk related to the translation of financial statements of our foreign operations into U.S. dollars, our functional currency. Costs incurred and sales recorded by subsidiaries operating outside of the United States are translated into U.S. dollars using exchange rates effective during the respective period. As a result, we are exposed to movements in the exchange rates of various currencies against the U.S. dollar. Currency exposures have increased as a result of the GPT Acquisition, which incurs a substantial portion of its expenses in Swedish Krona, while most revenue contracts for GPT are in U.S. Dollars and euros. Therefore, when the Swedish Krona strengthens or weakens against the U.S. dollar, operating profits are decreased or increased, respectively. The effect of a change in currency exchange rates on our international subsidiaries' assets and liabilities is reflected in the accumulated other comprehensive income component of stockholders’ equity.
 
To the extent material, we have discussed the impact of the change in foreign currency within Item 7. "Results of Operations." A hypothetical 10 percent reduction in currency exchange rates compared to the U.S. dollar (U.S. dollar weakening) would result in an estimated $170 after tax reduction in net earnings over a one-year period. Actual changes in market prices or rates may differ from hypothetical changes.
 
Interest Rates
 
Beginning during our year ended March 31, 2020, we held investments in money market funds. As a result, we are exposed to potential loss from market risks that may occur as a result of changes in interest rates, credit quality of the issuer, or other factors.
 
During our year ended March 31, 2021, we entered into the Credit Facility. Based on the Company’s variable-rate debt outstanding as of March 31, 2022, we estimate that a 1 percentage point increase in interest rates would have increased interest expense by $193 for the year ended March 31, 2022.
