Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our variable rate debt, including our unsecured revolving credit facility and commercial paper program, are reflected at fair value. At March 31, 2026, we had $2,866,865,000 outstanding related to our variable rate debt after considering the effects of interest rate swaps. Assuming no changes in outstanding balances, a 1% increase in interest rates would result in increased annual interest expense of $28,669,000. At December 31, 2025, we had $4,064,010,000 of outstanding variable-rate debt. Assuming no changes in outstanding balances, a 1% increase in interest rates would have resulted in increased annual interest expense of $40,640,000.

We are subject to currency fluctuations that may, from time to time, affect our financial condition and results of operations. Increases or decreases in the value of the Canadian Dollar or British Pounds Sterling relative to the U.S. Dollar impact the amount of net income we earn from our investments in Canada and the U.K. Based solely on our results for the three months ended March 31, 2026, a hypothetical 10% increase or decrease in the Canadian Dollar or British Pounds Sterling relative to the U.S. Dollar would result in a corresponding increase or decrease in our annualized net income from these investments of less than $53,000,000. We mitigate a portion of our foreign currency exposure through non-U.S. denominated borrowings and derivative instruments. Accordingly, the impact of changes in foreign currency exchange rates on our consolidated financial statements may differ from the sensitivity presented above. If we increase our international presence through investments in, or acquisitions or development of, seniors housing and healthcare properties outside the U.S., we may also decide to transact additional business or borrow funds in currencies other than U.S. Dollars, Canadian Dollars or British Pounds Sterling.

We have entered into various foreign currency debt obligations. As of March 31, 2026, the total principal amount of foreign currency debt obligations was $4,384,611,000, including $1,384,110,000 denominated in Pounds Sterling and $3,000,501,000 denominated in Canadian Dollars. Fluctuations in the exchange rates between these foreign currencies and the U.S. Dollar will impact the amount of U.S. Dollars that we will require to settle the foreign currency debt obligations at maturity. If the U.S. Dollar would have been weaker or stronger by 1% in comparison to these foreign currencies as of March 31, 2026, we estimate our obligation to cash settle the principal of these foreign currency debt obligations in U.S. Dollars would have increased or decreased by approximately $43,846,000. A portion of our Pounds Sterling-denominated debt is hedged through cross currency swaps designated as fair value hedges, which are intended to substantially offset the impact of changes in foreign exchange rates on that exposure.

We are also party to foreign currency forward and cross currency swap contracts used to manage foreign currency exposures, including net investment hedging activities. As of March 31, 2026, the total notional amount of cross currency swap contracts, other than those designated as fair value hedges, was $18,146,381,000, including $11,640,639,000 denominated in Pounds Sterling and $6,505,742,000 denominated in Canadian Dollars. If the U.S. Dollar weakened or strengthened by 1% in comparison to foreign currencies, we estimate our obligation to cash settle these hedges would have increased or decreased by approximately $181,464,000.
