Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

Our interest rate risk management objective is to limit the impact of future interest rate changes on our earnings and cash flows. To achieve this objective, our consolidated subsidiaries primarily borrow on a fixed-rate basis for longer-term debt issuances. As of March 31, 2023, we had $17.1 billion aggregate principal amount of outstanding indebtedness, of which 99.4% has fixed rate interest and 0.6% has a variable interest rate, representing the US$103.6 million (denominated in CAD) outstanding under our Revolving Credit Facility.

Additionally, we are exposed to interest rate risk between the time we enter into a transaction and the time we finance the related transaction with long-term fixed-rate debt. In addition, when that long-term debt matures, we may have to refinance such debt at a higher interest rate. In a rising interest rate environment, we have from time to time and may in the future seek to mitigate that risk by utilizing forward-starting interest rate swap agreements, treasury locks and other derivative instruments. Market interest rates are sensitive to many factors that are beyond our control.

Capital Markets Risks

We are exposed to risks related to the equity capital markets, and our related ability to raise capital through the issuance of our common stock or other equity instruments. We are also exposed to risks related to the debt capital markets, and our related ability to finance our business through long-term indebtedness, borrowings under credit facilities or other debt instruments. As a REIT, we are required to distribute a significant portion of our taxable income annually, which constrains our ability to accumulate operating cash flow and therefore requires us to utilize debt or equity capital to finance our business. We seek to mitigate these risks by monitoring the debt and equity capital markets to inform our decisions on the amount, timing, and terms of capital we raise.
