Syntax

bondmoddur2(cpn;mat;dcb;issu;first;freq;setl;price)

Input

Argument	Type	Description
`cpn`	integer or decimal	The annual coupon rate expressed as a percentage A scalar value or the name of a column
`mat`	integer	The maturity date A scalar value or the name of a column
`dcb`	text	The day count basis (dcb) A text value or the name of a column Generally, `dcb` should be `'ACTACT'` for U.S. Treasury Notes and Bonds and `'I30360'` for U.S. corporate bonds. For more information, see Daily count basis.
`issu`	integer	The original dated date A scalar value or the name of a column
`first`	integer	The first coupon date A scalar value or the name of a column The first coupon date and the maturity date must be a whole number of `freq` periods apart.
`freq`	integer	The number of coupon payments per year (e.g., 2 for semiannual) A scalar value or the name of a column
`setl`	integer	The settlement date The `setl` argument must be a valid date and cannot be a column name or N/A.
`price`	integer or decimal	The price (without accrued interest) expressed as a percentage A scalar value or the name of a column

Note: One of the arguments must reference a column. This does not include setl, which cannot be a column name.

Return Value

Returns the modified duration of the bond as a decimal value.

The bondmoddur2(cpn;mat;dcb;issu;first;freq;setl;price) function handles N/A values as follows:

If cpn, mat, or price are N/A, the result is N/A.
If dcb is N/A, actual/actual is used.
If freq is N/A, it is assumed to be 2 (semiannual).
If issu is N/A, it is assumed to be 30 years prior to maturity.
If first is N/A, it is assumed to be the first date after issue that is an integral number of payment periods from maturity.
