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.
