Weighted Average Maturity
Generally, the Weighted Average Maturity of a Bond Issue is the sum of the product of the Issue Price of each maturity of the Bond Issue multiplied by the number of years from the Closing until that Maturity Date divided by the Issue Price of the entire Bond Issue. The Weighted Average Maturity of a Tax-Exempt Bond Issue is important for a number of purposes under the Code and Treasury Regulations (see the “120% Rule”) and must be reported to the Internal Revenue Service (IRS) on the applicable Form 8038.
