Consider a borrower who purchased a $300,000 home using conventional conforming financing at 90% LTV. The underwriting approval requires private mortgage insurance (PMI) with 30% coverage. Suppose over time the borrower pays down the principal of the loan to a balance of $261,333, but is no longer able to make any additional payments and defaults. If the servicer were to foreclose on the collateral property and sell it clearing $160,272 in net proceeds, how much is the loss of principal taking into consideration the protection provided by the mortgage insurance policy?

(Input your answer rounded to the nearest whole dollar and without the $ or negative signs, e.g., input a loss of -$100,000 as 100,000)
