A pool of mortgages contains 3.75%, 30-year loans with the total beginning balance of $100 million. The pool backs 75 principal-only (PO) shares and 97 interest-only (IO) shares. Monthly expenses and fees amount to 0.04% of the beginning-of-the-month balance (they are subtracted from the interest portion). In the first month, the total payments from the pool were $461.7 thousand. What was the cash flow per IO share (to the nearest dollar)? Assume no defaults.
