ECL = PD × LGD × EAD. PD = probabilitas default, LGD = loss given default (1 − recovery), EAD = exposure at default. PSAK 71 menggantikan PPAP incurred-loss dengan model forward-looking 3-stage: Stage 1 (12-bulan), Stage 2 (lifetime, SICR), Stage 3 (default).
Glosarium: SICR = Significant Increase in Credit Risk (pemicu migrasi ke Stage 2); PPAP = Pembentukan Penyisihan Aktif Produktif (lama, incurred-loss); CKPN = Cadangan Kerugian Penurunan Nilai (nama PSAK 71 untuk ECL).
