Item 7A. Quantitative and Qualitative Disclosures about Market Risk Interest Income Our investment portfolio includes cash, cash equivalents, short-term investments and long-term investments. Our main investment objectives are the preservation of investment capital and the maximization of after-tax returns on our investment portfolio. Our interest income is sensitive to changes in the general level of U.S. interest rates. Our investment portfolio holdings as January 1, 2022 and January 2, 2021 yielded less than 100 basis points. A decline in yield to zero basis points on our investment portfolio holdings as of January 1, 2022 and January 2, 2021 would decrease our future annual interest income by approximately $3.6 million and $5.2 million, respectively. We believe that our investment policy, which defines the duration, concentration, and minimum credit quality of the allowable investments, meets our investment objectives. Interest Expense We are exposed to interest rate fluctuations in the normal course of our business, including through our credit facility. The interest rate on the credit facility consists of a variable rate of interest and an applicable margin. While we have drawn from the credit facility in the past, we have no borrowings as of January 1, 2022. If we borrow from the credit facility in the future, we will again be exposed to interest rate fluctuations. Foreign currency exchange rate risk We are exposed to foreign currency exchange rate risk primarily through assets, liabilities and operating expenses of our subsidiaries denominated in currencies other than the U.S. dollar. Our foreign subsidiaries are considered to be extensions of the U.S. parent. The functional currency of the foreign subsidiaries is the U.S. dollar. Accordingly, gains and losses resulting from remeasuring transactions denominated in currencies other than U.S. dollars are recorded in the Consolidated Statements of Income. We use foreign currency forward contracts to manage exposure to foreign exchange risk. Gains and losses on foreign currency forward contracts are recognized in earnings in the same period during which the hedged transaction is recognized. Investments in Auction-rate Securities As of January 1, 2022, we held $6.0 million par value auction-rate securities, all of which have experienced failed auctions because sell orders exceeded buy orders. We are unable to predict if these funds will become available before their maturity dates. Additionally, if we determine that a credit-related decline in the fair value of any of our available-for-sale auction-rate securities has occurred, we may be required to adjust the carrying value of the investments through an impairment charge. ​ Item 8.
