Invalid Elements Used On Range Axis

Rule function

This rule identifies where filers have used either of the following elements with the RangeAxis:

1. OperatingLeaseWeightedAverageRemainingLeaseTerm1
2. FinanceLeaseWeightedAverageRemainingLeaseTerm1

If these elements are used with any member on the RangeAxis then the rule will flag an error.

Problem solved by the rule

The intent of the rule is to allow filers to check that their filing is consistent with the FASB’s XBRL implementation guide. These elements, because they are weighted average elements, should not have a maximum or minimum value. If the filer wants to report the values of the minimum and the maximum lease terms for a lease they should use extension elements that reflect this. For example, OperatingLeaseRemainingLeaseTerm for operating leases or FinanceLeaseRemainingLeaseTerm for finance leases. The FASB plans to add additional elements to the US-GAAP taxonomy in 2020 to provide for this disclosure.

Example rule message

The element OperatingLeaseWeightedAverageRemainingLeaseTerm1 with a value of P1Y has been reported in the filing using the range axis. This element cannot be used with the range axis. To record the range of remaining lease terms use an extension element called OperatingLeaseRemainingLeaseTerm for operating leases and an extension element called FinanceLeaseRemainingLeaseTerm for finance leases.
