Hope this helps a little.

Hi Bob,

Still scratching my head :-)

From page 87, example 1 of HP92 Investor Apps Manual...

Semi annual
30/360 basis
Issue date = JUL 6, 1976
Settlement = AUG 23, 1976 (47 days)
Maturity = DEC 20, 1976 (117 days)

My guesses...
Issue date = start of coupon period
End of coupon period = 180 - (47 + 117) = 16 days after maturity
E (seems) to be days between Issue and Maturity (164 days)

Using the HP-92 to manually key in the calculation on 113 of HP-92 manual, I get an answer of 100.036. (Rounded = 100.34) The manual states an answer of 100.03

There is a small discrepancy which I cannot account for, which could mean the method I am using is still in error.

I think I have the accrued interest calculations working now for both 30/360 and actual/360.

cheers
