Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There have been no significant changes in our interest rate risk, foreign currency exchange rate exposure, marketable securities price risk or raw material price risk from the information we provided in our Annual Report on Form 10-K for the year ended December 31, 2021, except as noted below.

During the first quarter of 2021, we repaid the remaining principal balance of our 1.875% Euro-denominated senior notes. Prior to this repayment, the carrying value these notes was designated as an effective hedge of our net investment in certain foreign subsidiaries where the Euro serves as the functional currency, and gains or losses on the revaluation of these senior notes to our reporting currency were recorded in accumulated other comprehensive loss. Upon repayment of these notes, this net investment hedge was discontinued. The balance of foreign exchange revaluation gains and losses associated with this discontinued net investment hedge will remain within accumulated other comprehensive loss until the hedged net investment is sold or liquidated.

We had variable interest rate borrowings of $264.0 million outstanding at June 30, 2022, bearing a weighted average interest rate of 2.59% and representing 8% of our total outstanding debt. A hypothetical 100 basis point increase in the interest rate applicable to these borrowings would change our annualized interest expense by approximately $2.6 million as of June 30, 2022. We may enter into interest rate swaps, collars or similar instruments with the objective of reducing interest rate volatility relating to our borrowing costs.

Our financial instruments, which are subject to foreign currency exchange risk, consist of foreign currency forward contracts with an aggregate notional value of $452.9 million and with a fair value representing a net asset position of $4.9 million at June 30, 2022. Fluctuations in the value of these contracts are generally offset by the value of the underlying exposures being hedged. We conducted a sensitivity analysis on the fair value of our foreign currency hedge portfolio assuming an instantaneous 10% change in select foreign currency exchange rates from their levels as of June 30, 2022, with all other variables held constant. A 10% appreciation of the U.S. Dollar against foreign currencies that we hedge would result in a decrease of approximately $36.0 million in the fair value of our foreign currency forward contracts. A 10% depreciation of the U.S. Dollar against these foreign currencies would result in an increase of approximately $40.1 million in the fair value of our foreign currency forward contracts. The sensitivity of the fair value of our foreign currency hedge portfolio represents changes in fair values estimated based on market conditions as of June 30, 2022, without reflecting the effects of underlying anticipated transactions. When those anticipated transactions are realized, actual effects of changing foreign currency exchange rates could have a material impact on our earnings and cash flows in future periods.
