Payments based on legislation comparable to and having a similar effect as those listed in this paragraph may also qualify as having been made under a statute. Back pay under a statute, excluding penalties, is wages if paid for covered employment. It is allocated to the periods of time in which it should have been paid if the employer had not violated the statute. For backpay awards affecting periods prior to 1987, a State must fill a wage report and pay the contributions due for all periods involved in the back pay award under the rules applicable to those periods.
