Why JLPT N1 learners mix up 補足 (ほそく, “supplement, complement”) and 決算 (けっさん, “balance sheet, settlement of accounts”).
Both involve the final stages of data processing. Supplementing (補足) information and the settlement of accounts (決算) are both corrective or concluding actions performed at the end of a professional reporting period.
On JLPT N1, this pair shows up as a vocabulary meaning question. You see one word and pick its English equivalent from four options — one of which will be the other word in this pair, chosen as a distractor precisely because of the overlap.
