Incorrect Period Reported

Rule function

This rule checks that period reported for the 10-K or 20-F is a valid annual period. The rule identifies the concepts used in the Income Statement and identifies those facts that match the DocumentPeriodEndDate start date and end date. It then identifies those durational periods that have a matching end date but a different start date. If the number of annual periods is less than the total count of other durations on the financial statements then an error is returned.

The rule will not run in those cases where the filer has indicated that the report is a transition period, is the year of inception or is a successor or predecessor entity.

The filer can indicate these conditions by performing the following:

• Define an extension element called TransitionReport with a value.
• Define an extension element Called YearOfInception with a value.
• Define a value of true for the dei element DocumentTransitionReport.
• Define a value of true for the us-gaap element FinancialDesignationPredecessorAndSuccessorFixedList.

Problem solved by the rule

The rule is intended to ensure that filers do not enter the incorrect start date on the values reported in the financial statements.

Example rule message

The company has reported a 10-K or 20-F but the majority of the values reported on the Income Statement are for a period other than a year. Please check that the values used on the Income Statement represent a full year for the required reporting period.
