Stub

A type defining how a stub calculation period amount is calculated and the start and end date of the stub. A single floating rate tenor different to that used for the regular part of the calculation periods schedule may be specified, or two floating rate tenors many be specified. If two floating rate tenors are specified then Linear Interpolation (in accordance with the 2000 ISDA Definitions, Section 8.3 Interpolation) is assumed to apply. Alternatively, an actual known stub rate or stub amount may be specified.

For example, a 2 month stub period may use the linear interpolation of a 1 month and 3 month rate. The different rates would be specified in this component. Note that a maximum of two rates can be specified. If a stub period uses the same floating rate index, including tenor, as the regular calculation periods then this should not be specified again within this component, i.e. the stub calculation period amount component may not need to be specified even if there is an initial or final stub period. If a stub period uses a different floating rate index compared to the regular calculation periods then this should be specified within this component.

Stub

A choice of stub value.

floatingRate(FloatingRate)

The rates to be applied to the initial or final stub may be the linear interpolation of two different rates. While the majority of the time, the rate indices will be the same as that specified in the stream and only the tenor itself will be different, it is possible to specify two different rates. For example, a 2 month stub period may use the linear interpolation of a 1 month and 3 month rate. The different rates would be specified in this component. Note that a maximum of two rates can be specified. If a stub period uses the same floating rate index, including tenor, as the regular calculation periods then this should not be specified again within this component, i.e. the stub calculation period amount component may not need to be specified even if there is an initial or final stub period. If a stub period uses a different floating rate index compared to the regular calculation periods then this should be specified within this component. If specified here, they are likely to have id attributes, allowing them to be referenced from within the cashflows component.

floatingRateIndex(FloatingRateIndex)

	Defines floating rate index.
	Float rate code.

indexTenor(Period)

The ISDA Designated Maturity, i.e. the tenor of the floating rate.

periodMultiplier(integer)

	A time period multiplier, e.g. 1, 2 or 3 etc. A negative value can be used when specifying an offset relative to another date, e.g. -2 days.

period(PeriodEnum)

	A time period, e.g. a day, week, month or year of the stream. If the periodMultiplier value is 0 (zero) then period must contain the value D (day).
	D;W;M;Y;

floatingRateMultiplierSchedule(Schedule)

A rate multiplier or multiplier schedule to apply to the floating rate. A multiplier schedule is expressed as explicit multipliers and dates. In the case of a schedule, the step dates may be subject to adjustment in accordance with any adjustments specified in the calculationPeriodDatesAdjustments. The multiplier can be a positive or negative decimal. This element should only be included if the multiplier is not equal to 1 (one) for the term of the stream.

initialValue(decimal)

	The initial rate or amount, as the case may be. An initial rate of 5% would be represented as 0.05.

step(Step)

	The schedule of step date and value pairs. On each step date the associated step value becomes effective. A list of steps may be ordered in the document by ascending step date. An FpML document containing an unordered list of steps is still regarded as a conformant document.

stepDate(date)

	The date on which the associated stepValue becomes effective. This day may be subject to adjustment in accordance with a business day convention.

stepValue(decimal)

	The rate or amount which becomes effective on the associated stepDate. A rate of 5% would be represented as 0.05.

spreadSchedule(SpreadSchedule)

The ISDA Spread or a Spread schedule expressed as explicit spreads and dates. In the case of a schedule, the step dates may be subject to adjustment in accordance with any adjustments specified in calculationPeriodDatesAdjustments. The spread is a per annum rate, expressed as a decimal. For purposes of determining a calculation period amount, if positive the spread will be added to the floating rate and if negative the spread will be subtracted from the floating rate. A positive 10 basis point (0.1%) spread would be represented as 0.001.

initialValue(decimal)

	The initial rate or amount, as the case may be. An initial rate of 5% would be represented as 0.05.

step(Step)

	The schedule of step date and value pairs. On each step date the associated step value becomes effective. A list of steps may be ordered in the document by ascending step date. An FpML document containing an unordered list of steps is still regarded as a conformant document.

	The rate or amount which becomes effective on the associated stepDate. A rate of 5% would be represented as 0.05.

capRateSchedule(StrikeSchedule)

	The cap rate or cap rate schedule, if any, which applies to the floating rate. The cap rate (strike) is only required where the floating rate on a swap stream is capped at a certain strike level. A cap rate schedule is expressed as explicit cap rates and dates and the step dates may be subject to adjustment in accordance with any adjustments specified in calculationPeriodDatesAdjustments. The cap rate is assumed to be exclusive of any spread and is a per annum rate, expressed as a decimal. A cap rate of 5% would be represented as 0.05.
