Hi all, some errors: The text 'Criterion', second line after '4.11.7.8 Procedure F' needs to be style 'Heading 3'. Some formulas have yellow background, but they should have no color: 6.5.1 General, 6.5.4 MMULT, 6.5.6 TRANSPOSE, In AMORLINC: 'When period = 0' should be 'When Period = 0' with 'Period' having character style 'Parameter Name'. There seem to be two superfluous line breaks around 'the depreciation = Cost - Salvage - accumulated-depreciation'. In DB: 'where Period LIfeTime' There is a typo in LIfeTime and it needs the character style 'Parameter Name'. In GAMMADIST: The formulas have an erroneous '%'. Kind regards Regina
