mbs_py_ai_b (routine)

Mortgage backed security - calculate the price/yield and accrued interest with balloon payment

Introduced in release: 1.0
Component: US MBS
Purpose: Calculates either dollar price or bond equivalent yield to maturity and It uses the monthly cash flows as input.

Special Considerations: This function differs from mbs_py_b in that it uses or returns the clean price (exclusive of accrued interest) as opposed to the dirty price (inclusive of accrued interest).

Notes: This routine takes as input cash flows which must first be calculated.

 To calculate the cash flows for a Fixed Rate MBS use mbs_gen_tbls.
 To calculate the cash flows for a GPM use mbs_gentblsg.
 To calculate the cash flows for an ARM use arm_gen_tbls. See Coding Examples for a more detailed explanation.

Results: The result is returned as the value of the function, accurate to as many places as supported by a double precision value.

Error Conditions: Returned values should be ignored for a non-zero status. See Errors.
