Oracle Documentation:

..."Allocate Annual Depreciation Across Periods

After calculating the annual depreciation amount, Oracle Assets uses your depreciation calendar, the divide depreciation flag, and the depreciate when placed in service flag to determine how much of the fiscal year depreciation to allocate to the period for which you ran depreciation.

If you choose to allocate depreciation evenly to each of your accounting periods, Oracle Assets divides the annual depreciation by the number of depreciation periods in your fiscal year to get the depreciation per period. If, however, you choose to allocate it according to the number of days in each period, Oracle Assets divides the annual depreciation by the number of days the asset depreciates in the fiscal year and multiplies the result by the number of days in the appropriate accounting period...."
