Our profitability, like most financial institutions, depends to a large extent upon our net interest income, which is the difference between our interest income on interest-earning assets, such as loans and securities, and our interest expense on interest-bearing liabilities, such as deposits and borrowed funds. Accordingly, our results of operations depend largely on movements in market interest rates and our ability to manage our interest-rate-sensitive assets and liabilities in response to these movements. Factors such as inflation, recession and instability in financial markets, among other factors beyond our control, may affect interest rates.
If interest rates rise, and if rates on our deposits and variable rate borrowings reprice upwards faster than the rates on our long-term loans and investments, we could experience compression of our interest rate spread, which would have a negative effect on our profitability. Conversely, decreases in interest rates can result in increased prepayments of loans and mortgage-related securities, as borrowers refinance to reduce their borrowing costs. Under these circumstances, we are subject to reinvestment risk, as we may have to redeploy such loan or securities proceeds into lower-yielding assets, which might also negatively impact our income.
Any substantial, unexpected, prolonged change in market interest rates could have a material adverse effect on our financial condition, liquidity and results of operations. Further, a prolonged period of exceptionally low market interest rates limits our ability to lower our interest expense, while the average yield on our interest-earning assets may continue to decrease as our loans reprice or are originated at these low market rates. Accordingly, our net interest income may decrease, which may have an adverse effect on our profitability. Also, our interest rate risk-modeling techniques and assumptions likely may not fully predict or capture the impact of actual interest rate changes on our balance sheet or projected operating results.
While we pursue an asset/liability strategy designed to mitigate our risk from changes in interest rates, changes in interest rates can still have a material adverse effect on our financial condition and results of operations. Changes in the level of interest rates also may negatively affect our ability to originate real estate loans, the value of our assets and our ability to realize gains from the sale of our assets, all of which ultimately affect our earnings.
