calc_90_percent_test | Averages the two semiannual testing dates and, if the fund falls short, computes the Form 8996 Part IV penalty month by month (pass month-end figures in monthly for an exact figure; otherwise testing-date figures are applied to each half-year and the result is flagged as an approximation) at an unde |
