FpML 5.3 Validation Rules - Rules for Interest Rate Derivatives (IRD) (confirmation view)

This is the Interest Rate Derivatives part of the validation rule set accompanying the FpML 5.3 Recommendation. The introductory section in the draft contains background information and documentation for this page.

The rules contained on this page contain links to cut down versions of valid and invalid test cases. These test cases have been analysed using Systemwire's xlinkit rule engine to highlight relevant document portions accessed by a rule. The cut down test cases are non-normative and are provided for the purpose of documentation only.

Definitions

Term: frequency equivalence
A frequency is specified as a tuple of period, which is an integer, and periodMultiplier, which is one of "D", "M", "Y", "W" or "T", standing for day, month, year, week and term. Between any pair of frequencies, the following is the complete list of equivalences where the period multipliers differ: iff(period elements are equal, If the period multipliers of a pair of frequencies are equivalent then they are equal). For the purpose of calculating multiples of periods, the following additional rule holds:
Term: unadjusted calculation period dates
This applies in the context of an InterestRateStream. For the purpose of validation, the unadjusted calculation period dates are determined as follows:
Term: the schedule implied by
The schedule defined by the effective- and termination-Date, together with the "RegularPeriod" dates which may appear optionally in the presence of stubs, and the calculation period frequency.

Conditions

-- There are no global conditions for IRD rules. --

Functions

The following shared functions are used in the rules.

English Description:
Context: CalculationPeriodDates (complex type)
If floatingRateIndex is not “CNY-CNREPOFIX=CFXS-Reuters”, the frequency specified in calculationPeriodFrequency must divide precisely the schedule of regular periods from the first regular period start date to the last regular period end date. This means that by stepping through the period from the start date at the specified frequency, it must be possible to reach the end date.
Comment: The technical paper “Financial Date Calculations in FpML” describes in detail how to handle this type of date calculations in the section with title “Dividing a Period by Intervals” and following. The paper explains also how to handle stub periods. The paper can be found in the “Documents” section on FpML.org. An XPath description is not available for this rule.
