By comparison, leading life expectancy providers have publicly reported A/E ratios close to 100%. Documents Show Abacus Knew Lapetus's Life Expectancy Estimates Were Chronically ShortOther unsealed documents show that Abacus was aware of the disparity between Lapetus's life expectancy estimates and those of other medical underwriters. Had Abacus referenced the Lewis & Ellis valuation calculated using Abacus's discount rate, the resulting valuation would not have been within 1% as Abacus claimed. In several instances, Abacus provided older - and shorter - life expectancy estimates while withholding more recent - and longer - estimates already in its possession. By supplying older, shorter estimates for several of its largest policies, Abacus caused those policies' valuations to be significantly inflated.
