The CA depreciation lives conform to the asset guideline classes and periods within IRS Revenue Procedure 83-35. To determine an asset's depreciation life, the application uses the value entered in the
PPT type - CA
field to determine which guideline class each asset belongs to. If that association is not turned on, is blank, or
Exempt
is entered, a determination of the asset class can't be completed and the life from the Tax treatment will be used. Then, based on other asset information, the application enters the method for the CA treatment. ("Other asset information" includes whether the asset is marked as Real Property and/or it is marked as used property on the Other tab, and the Method that was entered in the Tax treatment.)
