Abstract: A data processing system analyzes a stock investment limited recourse borrowing contract. The system receives and processes as input data on the date of analysis (1) contract data including the identity and amount of the collateral stock, the amount of the initial loan and the minimum and maximum interest rate percentages payable by the investor under the contract; (2) actual data relating to the stock prior to the analysis date including its market prices per share at selected regular intervals and the dividends per share paid in a selected number of quarters; and (3) estimated data relating to the stock from the analysis date to the end of the contract term including its estimated market price per share at intervals and the estimated dividends per share to be paid.
