COUPDAYSNC Function (Microsoft Excel)
vSettlement: Settlement date for the security. The date after the issue date when the security is traded to the buyer. Function returns Null if vSettlement is Null, cannot be interpreted as a Date, or is greater than the maturity date vMaturity. The time component of vSettlement (if any) is ignored.
vMaturity: Maturity date for the security. The date on which the security expires. Function returns Null if vSettlement is Null or cannot be interpreted as a Date. The time component of vMaturity (if any) is ignored.
vFrequency: Number of coupon payments per year. Use 1 for annual payments, 2 for semiannual payments, or 4 for quarterly payments. vFrequency is rounded to the nearest integer. Function returns Null if vFrequency is not 1, 2, nor 4.
vBasis: Optional day count basis that determines how to count the difference in days and years. One of the following day count basis constants: US_NASD_30_360, Actual_Actual, Actual_360, Actual_365, or European_30_360. vBasis defaults to US_NASD_30_360 if it is missing or Null or cannot be interpreted as a number. Function returns Null if vBasis is not one of the recognized Day Count Basis constants.
Note: This function does not match the Microsoft Excel COUPDAYSNC function in many cases when vBasis is US_NASD_30_360 (0) or European_30_360 (4).
