A firm has the following assets in its portfolio: $20 million in cash reserves with the Fed, $20 million in T-bills, and $50 million in mortgage loans. If it needs to dispose of its assets at short notice, it will receive only 99 % of the fair market value of the T-bills on 90% of the fair market value of its mortgage loans. If the firm waits one month to liquidate these assets, it will receive full fair market value for each security. What is the liquidity index?
