FpML
Per 2006 ISDA Definitions, Section 4.16. Day Count Fraction, paragraph (a) or Annex to the 2000 ISDA Definitions (June 2000 Version), Section 4.16. Day Count Fraction, paragraph (a).

ACT/ACT.ISDA
FpML
Per 2006 ISDA Definitions, Section 4.16. Day Count Fraction, paragraph (b) or Annex to the 2000 ISDA Definitions (June 2000 Version), Section 4.16. Day Count Fraction, paragraph (b). Note that going from FpML 2.0 Recommendation to the FpML 3.0 Trial Recommendation the code in FpML 2.0 'ACT/365.ISDA' became 'ACT/ACT.ISDA'.

ACT/ACT.ICMA
FpML
Per 2006 ISDA Definitions, Section 4.16. Day Count Fraction, paragraph (c)

ACT/ACT.ISMA
FpML
The Fixed/Floating Amount will be calculated in accordance with Rule 251 of the statutes, by-laws, rules and recommendations of the International Securities Market Association, as published in April 1999, as applied to straight and convertible bonds issued after December 31, 1998, as though the Fixed/Floating Amount were the interest coupon on such a bond.

ACT/ACT.AFB
FpML
The Fixed/Floating Amount will be calculated in accordance with the "BASE EXACT/EXACT" day count fraction, as defined in the "Definitions Communes plusieurs Additifs Techniques" published by the Association Francaise des Banques in September 1994.

ACT/365.FIXED
FpML
Per 2006 ISDA Definitions, Section 4.16. Day Count Fraction, paragraph (d) or Annex to the 2000 ISDA Definitions (June 2000 Version), Section 4.16. Day Count Fraction, paragraph (c).

ACT/360
FpML
Per 2006 ISDA Definitions, Section 4.16. Day Count Fraction, paragraph (e) or Annex to the 2000 ISDA Definitions (June 2000 Version), Section 4.16. Day Count Fraction, paragraph (d).

30/360
FpML
Per 2006 ISDA Definitions, Section 4.16. Day Count Fraction, paragraph (f) or Annex to the 2000 ISDA Definitions (June 2000 Version), Section 4.16. Day Count Fraction, paragraph (e).

Per 2006 ISDA Definitions, Section 4.16. Day Count Fraction, paragraph (g) or Annex to the 2000 ISDA Definitions (June 2000 Version), Section 4.16. Day Count Fraction, paragraph (f). Note that the algorithm defined for this day count fraction has changed between the 2000 ISDA Definitions and 2006 ISDA Definitions. See Introduction to the 2006 ISDA Definitions for further information relating to this change.

30E/360.ISDA
FpML
Per 2006 ISDA Definitions, Section 4.16. Day Count Fraction, paragraph (h). Note the algorithm for this day count fraction under the 2006 ISDA Definitions is designed to yield the same results in practice as the version of the 30E/360 day count fraction defined in the 2000 ISDA Definitions. See Introduction to the 2006 ISDA Definitions for further information relating to this change.
