Abstract

Abstract Methods and apparatus for restructuring one or more debt obligations issued in the form of interest-bearing bonds into a serial issue of zero coupon bonds. The data processing system evaluates the cash flows and present value of an existing bond, then creates a serial issue of zero coupon bonds which provides pretax cash flows equivalent to those of the existing bond and determines a table of call yields for the serial issue of zero coupon bonds to replace the table of call prices for the old bond. The system evaluates the after-tax cash flows, and determines the after-tax present value to the issuer of the existing bond and the serial issue of zero coupon bonds. The system periodically determines the potential savings from calling the zero coupon bond issue, or selected bonds from the series, and refinancing the debt at the prevailing interest rates.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 333 words
A data processing system for implementing a debt-for-debt exchange to restructure an issuer's existing debt issue into a serial issue of callable zero coupon bonds so that debt service payments after the exchange are substantially equivalent to debt service payments prior to the exchange, said existing debt issue and said serial issue of callable zero coupon bonds each having a respective sequence of cash payment obligations, a respective present value, and a respective cost of calling, said exchange occurring on a settlement date, said method comprising: means for entering parameters which define the existing debt issue, said parameters including a maturity date and a table of call price values; means for analyzing one or more of said parameters to determine the issuer's cash payment obligations for each of a succession of payment periods from the settlement date of said exchange to the maturity date of the existing debt issue; means for determining a face value for each maturity of the serial issue of callable zero coupon bonds so that the sequence of cash payment obligations associated with the serial issue of callable zero coupon bonds is substantially equivalent to the sequence of cash payment obligations of said existing debt issue and so that the present value of said serial issue of callable zero coupon bonds equals the present value of said existing debt issue; means for transforming the table of call price values for the existing debt issue into a table of call yield values for the serial issue of callable zero coupon bonds so that the cost of calling the entire serial issue of callable zero coupon bonds is substantially the same as the cost of calling the existing debt issue at any data on which the existing debt issue can be called; and means for printing certificates evidencing each separate bond issue in the new serial issue of callable zero coupon bonds and for printing the table of call yield values for the new seria issue of callable zero coupon bonds.
Claim 2
Dependent Claim 333 words
A data processing system for implementing a debt-for-debt exchange to restructure an issuer's existing debt issue into a serial issue of callable zero coupon bonds so that debt service payments after the exchange are substantially equivalent to debt service payments prior to the exchange, said existing debt issue and said serial issue of callable zero coupon bonds each having a respective sequence of cash payment obligations, a respective present value, and a respective cost of calling, said exchange occurring on a settlement date, said method comprising: means for entering parameters which define the existing debt issue, said parameters including a maturity date and a table of call price values; means for analyzing one or more of said parameters to determine the issuer's cash payment obligations for each of a succession of payment periods from the settlement date of said exchange to the maturity date of the existing debt issue; means for determining a face value for each maturity of the serial issue of callable zero coupon bonds so that the sequence of cash payment obligations associated with the serial issue of callable zero coupon bonds is substantially equivalent to the sequence of cash payment obligations of said existing debt issue and so that the present value of said serial issue of callable zero coupon bonds equals the present value of said existing debt issue; means for transforming the table of call price values for the existing debt issue into a table of call yield values for the serial issue of callable zero coupon bonds so that the cost of calling the entire serial issue of callable zero coupon bonds is substantially the same as the cost of calling the existing debt issue at any data on which the existing debt issue can be called; and means for printing certificates evidencing each separate bond issue in the new serial issue of callable zero coupon bonds and for printing the table of call yield values for the new seria issue of callable zero coupon bonds.
Claim 3
Dependent Claim 334 words
A data processing method for implementing a debt-for-debt exchange to restructure an issuer's existing debt issue into a serial issue of callable zero coupon bonds so that debt service payments after the exchange are substantialy equivalent to debt service payments prior to the exchange, said existing debt issue and said serial issue of callable zero coupon bonds each having a respective sequence of cash payment obligations, a respective present value, a respective cost of calling, a respective market value, and respective after-tax cash flows, said exchange occurring on a settlement data, said method comprising the steps of: entering parameters which define the existing debt issue, said parameters including a maturity date and a table of call price values; analyzing one or more of said parameters to determine the issuer's cash payment obligations for each of a succession of payment periods from the settlement date of said exchange to the maturity date of the existing debt issue; determining a face value for each maturity of the serial issue of callable zero coupon bonds so that the sequence of case payment obligations associated with the serial issue of callable zero coupon bonds is substantially equivalent to the sequency of cash payment obligations of said existing debt issue and so that the present value of said serial issue of callable zero coupon bonds equals the present value of said existing debt issue; transforming the table of call price values for the existing debt issue into a table of call yield values for the serial issue of callable zero coupon bonds so that the cost of calling the entire serial issue of callable zero coupon bonds is substantially the same as the cost of calling the existing debt issue at any date on which the existing debt issue can be called; and printing certificates evidencing each separate bond issue in the new serial issue of callable zero coupon bonds and for printing the table of call yield values for the new serial issue of callable zero coupon bonds.
Claim 4
Dependent Claim 334 words
A data processing method for implementing a debt-for-debt exchange to restructure an issuer's existing debt issue into a serial issue of callable zero coupon bonds so that debt service payments after the exchange are substantialy equivalent to debt service payments prior to the exchange, said existing debt issue and said serial issue of callable zero coupon bonds each having a respective sequence of cash payment obligations, a respective present value, a respective cost of calling, a respective market value, and respective after-tax cash flows, said exchange occurring on a settlement data, said method comprising the steps of: entering parameters which define the existing debt issue, said parameters including a maturity date and a table of call price values; analyzing one or more of said parameters to determine the issuer's cash payment obligations for each of a succession of payment periods from the settlement date of said exchange to the maturity date of the existing debt issue; determining a face value for each maturity of the serial issue of callable zero coupon bonds so that the sequence of case payment obligations associated with the serial issue of callable zero coupon bonds is substantially equivalent to the sequency of cash payment obligations of said existing debt issue and so that the present value of said serial issue of callable zero coupon bonds equals the present value of said existing debt issue; transforming the table of call price values for the existing debt issue into a table of call yield values for the serial issue of callable zero coupon bonds so that the cost of calling the entire serial issue of callable zero coupon bonds is substantially the same as the cost of calling the existing debt issue at any date on which the existing debt issue can be called; and printing certificates evidencing each separate bond issue in the new serial issue of callable zero coupon bonds and for printing the table of call yield values for the new serial issue of callable zero coupon bonds.
Claim 5
Dependent Claim 69 words
The method of claim 2, further comprising; evaluating the market value of the serial issue of callable zero coupon bonds; evaluating said after-tax cash flows of the existing debt issue to determine a present value for the after-tax cash flows of the existing debt issue which occur after the settlement date; calculating a net present value of the debt-for-debt exchange by subtracting said market value from said present value.
Claim 6
Dependent Claim 40 words
The method of claim 2, further comprising: evaluating, for each zero coupon bond in said serial issue of callable zeo coupon bonds, any potential savings to be gained by calling the bond for redemption and refinancing at prevailing interest rates.
