1.1 ,This practice covers guidance as to the proper treatment for accounting and accountability purposes when items are still retained but need to be recognized as impaired or retired to administrative control. This practice is intended to be used in conjunction with Practice E2279, which provides various principles to improve the effectiveness and efficiency of the property management functions. These include the concepts of materiality, best value, reasonable detail, and reasonable assurance and proper reporting. During the life cycle of property management, appropriate action must be taken at the appropriate time to be in conformance with these principles. The objective, on behalf of the owner, is to maintain property accounting records that adequately represent the appropriate book value of the property and for accountability purposes apply the appropriate management and oversight for the proper protection and safeguarding of assets.
