The CPA firm used to use dollar unit sampling.
Easiest way to explain get loans in a random order. Start adding up the balances. Example, using $2million - When adding up, whatever loan hits $2MM is selected randomly.an that csuses total to hit $4MM is selected, etc a nausium! Larger loans with higher potential loss would have a greater chance of being selected, but all loans could be selected.
Watch list items, selected for risk and reserves done separetly.
