The payer and receiver credit default swap options are computed using the Black's model as described in O'Kane [1]:
where
RPV01is the risky present value of a basis point (seecdsrpv01
).
Φis the normal cumulative distribution function.
σis the spread volatility.
tis the valuation date.
tEis the option expiry date.
Tis the CDS maturity date.
Fis the forward spread (from option expiry to CDS maturity).
Kis the strike spread.
FEPis the front-end protection (from option initiation to option expiry).
