23. Field 38G: Designated Maturity

FORMAT

Option G 2n1!a/2n1!a (Number From)(Period From)(Number To)(Period To)

PRESENCE

Mandatory in mandatory subsequence B2

DEFINITION

This field specifies the designated maturities of the rate source.

For an ISDA Master (Type in field 77H = ISDA), this field specifies the Designated Maturity as per ISDA definitions.

CODES

Period From and Period To must be specified using one of the following codes (Error code(s): T48):

D Daily
M Monthly
O The designated maturity is specified in field 72.
W Weekly
Y Yearly

USAGE RULES

This field specifies the tenor for the interest rate. For example, a deal that starts in 3 months and ends in 9, has a 6 months tenor; in this case 38G contains 6M/6M as it is the 6 months rate; here both subfields have the same value.

For interpolation, this field specifies the two designated maturities.

When there is no interpolation, Period-From and Period-To must be the same designated maturity.
