Eric Patterson updated OFFICE-2704:
-----------------------------------


From Excel:
ACCRINT(issue, first_interest, settlement, rate, par, frequency, [basis], [calc_method]) Important   Dates should be entered by using the DATE function, or as results of other formulas or functions. For example, use DATE(2008,5,23) for the 23rd day of May, 2008. Problems can occur if dates are entered as text.

The ACCRINT function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

Issue    Required. The security's issue date.
First_interest    Required. The security's first interest date.
Settlement    Required. The security's settlement date. The security settlement date is the date after the issue date when the security is traded to the buyer.
Rate    Required. The security's annual coupon rate.
Par    Required. The security's par value. If you omit par, ACCRINT uses $1,000.
Frequency    Required. The number of coupon payments per year. For annual payments, frequency = 1; for semiannual, frequency = 2; for quarterly, frequency = 4.
Basis    Optional. The type of day count basis to use.
Basis Day count basis 
0 or omitted US (NASD) 30/360 
1 Actual/actual 
2 Actual/360 
3 Actual/365 
4 European 30/360 

Calc_method    Optional. A logical value that specifies the way to calculate the total accrued interest when the date of settlement is later than the date of first_interest. A value of TRUE (1) returns the total accrued interest from issue to settlement. A value of FALSE (0) returns the accrued interest from first_interest to settlement. If you do not enter the argument, it defaults to TRUE.

> The description of ACCRINT has several issues:
> 1) The constraint is given as: issue < first < settlement ; coupon > 0; par > 0. OOo and Excel clearly permit settlement<first and most examples on the web seem to be of that kind.
> 2) The short description of calc_method reads "A logical value that specifies how to treat the case where settlement>first." which seems to imply that there is a permitted case where settlement > first does not hold.
> 3) The formula given contains the undefined  variables start-of-period and end-of-period. Especially in view of the statement "ACCRINT
> supports short, standard, and long coupon periods.", it is not clear what those values are.
> 4) If the constraint is changed, a formula for the settlement < first case is needed.
