We use a variety of strategies to hedge a portion of our exposure to market risks, primarily interest rate risk and associated risks, including prepayment risk and extension risk. Our risk management strategy takes into consideration our risk / return profile for the current environment and incorporates our investment strategy, the cost of hedging transactions, and our intention to continue to qualify as a REIT. Our hedging strategies are generally not designed to protect our net asset value from spread risk.
The principal instruments that we use to hedge a portion of our exposure to interest rate, prepayment, and extension risks are interest rate swaps and interest rate swaptions. We also utilize TBA contracts, U.S. Treasury securities, and U.S. Treasury futures contracts, primarily through short sales.
As of March 31, 2022, our interest rate hedge portfolio totaled $77.5 billion and covered 121% of our repo funding, other debt and net TBA position.

Duration is a measurement of market price sensitivity to interest rate movements and represents the estimated percentage change in the market value of our mortgage assets and our hedge portfolio caused by a parallel change in short- and long-term interest rates. The duration of our investment portfolio tends to increase when interest rates rise and decrease when interest rates fall.
As of March 31, 2022, we had a net duration gap of 0.3 years.
