To ensure appropriate valuation of accounts receivable, management performs a quarterly review of the calculation for the allowance for doubtful accounts. The inputs, activities, and outputs of this review are as follows: Inputs On a quarterly basis, Tyler, the AR clerk, creates an aged AR schedule and calculation of the allowance for doubtful accounts. Tyler agrees total AR per the aging schedule to the trial balance and foots and crossfoots the schedule before providing the schedules to Gavin. Specific quarterly review activities Gavin, the CFO, obtains schedules from Tyler and 1) reviews each of the percentage assumptions for reasonableness based on experience, 2) compares each aging category's total balance to the average corresponding aging category balance from the previous two years, 3) considers external factors affecting the industry and specific customers, and 4) identifies differences (i.e., deviations) as either any aging category whose balance exceeds the two-year average by greater than 2 percent or any other specific transactions or customer balances that appear unusual. Outputs Gavin (CFO) discusses identified deviations with Emma (controller) and Tyler (AR clerk). After resolving any identified deviations, Gavin signs off on the schedules.
