Lower Cumulative Offline Transaction Amount is M/Chip's own accumulated-spending threshold, related to its sibling Upper Cumulative Offline Transaction Amount (CB, covered alongside it here) and to the core Offline Balance (9F50, covered earlier) that this pair of limits governs - conceptually parallel to the core Lower and Upper Consecutive Offline Limit tags (9F14/9F23, covered earlier) but measuring cumulative amount spent rather than consecutive transaction count, the two being complementary risk dimensions an issuer can bound independently. Crossing the lower threshold typically triggers additional risk scrutiny short of forcing an online transaction outright, with CB representing the harder ceiling that does force it - the same graduated-response design already described for the core consecutive-offline-limit pair, just applied to cumulative amount instead of transaction frequency. Its source citation carries the export's verificar vigencia flag, preserved unchanged. See Mastercard M/Chip 4 Card Application Specification.
