Carter Company sells on credit with terms of n/30. For the $500,000 of accounts at the end of the year that are not overdue, there is a 90% probability of collection. For the $200,000 of accounts that are less than a month past due, Carter estimates the likelihood of collection going down to 70%. The probability of collecting the $100,000 of accounts more than a month past due is estimated to be 25%.
