Teeming and ladding

This is the method by which the deficiencies of cash are concealed for sometime. When cash  is received from some debtor, it is not recorded in the cash books and is misappropriate. Later on, when cash is received from any other debtor, his account is not credited but the account of the first debtor is credited and cash is debited, again later on, when cash is received from their debtor, his account is not credited but that of the second debtor in credited and cash is debited.
