Methods, software programs, and systems for managing one or more liabilities

A processor-implemented method for managing borrower-issued debt, comprising:

• electronically obtaining an expected principal amortization period associated with a first credit issued by a borrower, wherein the first credit is included as debt;
• processor-adjusting the expected principal amortization period associated with the first credit, said adjustment of the expected principal amortization period associated with the first credit resulting in an extension of the expected principal amortization period associated with the first credit;
• and
• electronically applying, during a time period when a benchmark interest rate is below a predetermined interest rate level, at least part of an amount made available from the adjustment to at least partially defease a second credit when a yield on the second credit is above a yield on the first credit and the second credit is callable, wherein the second credit is issued by the borrower and included in the debt.

A method implemented by a programmed computer system for managing debt issued by a borrower, comprising:

• obtaining, with the computer system, an expected principal amortization period associated with a first credit, the first credit issued by a borrower and included in a debt, wherein the first credit is a series of variable rate demand bonds;
• adjusting, with the computer system, the expected principal amortization period associated with the first credit, said adjustment of the expected principal amortization period associated with the first credit resulting in an extension of the expected principal amortization period associated with the first credit;
• and
• applying, when a yield on the second credit is above a yield on the first credit, at least part of an amount made available from the adjustment made with the computer system to at least partially defease a second credit, wherein the second credit is issued by the borrower and included in the debt, wherein the second credit forms a variable rate credit,
• wherein the first and second credits are issued at different time,
• wherein applying at least part of the amount made available from the adjustment made with the computer system to at least partially defease the second credit is obligated, wherein the obligation result from a practice of the borrower.
