The document discusses interest rate risk management techniques used by companies. It describes two main types of interest rate risk: mismatching of interest rate bases for assets and liabilities, and mismatching in the timing of repricing interest rate sensitive assets and liabilities. To manage these risks, the document outlines various outright and option based instruments that companies can use, including interest rate swaps, forwards, caps, floors, and collars. The goal is for companies to forecast interest rates and select the appropriate tools to match their assets and liabilities.
