2.8 Assets That Provide No Future Benefit
An entity may determine that a specific asset within a larger asset
                group has no future benefit (e.g., when the asset is destroyed [as opposed to
                damaged], becomes obsolete, or is lost). Even if the asset group is determined to be
                recoverable as a whole, the entity would need to write off an asset that has no
                future benefit. 
            Example 2-4
                                Entity A provides ground delivery services
                                        to its customers through a fleet of trucks. Entity A has
                                        appropriately determined that its ground delivery business
                                        represents a “lowest level” for which identifiable cash
                                        flows are largely independent of the cash flows of other
                                        assets and liabilities. One truck in its delivery fleet has
                                        been destroyed in an accident. Entity A can continue to
                                        provide ground delivery services at the same level by using
                                        the remaining trucks in its fleet in such a way that the
                                        destroyed truck is not expected to be replaced. Although A
                                        expects no adverse change in expected cash flows as a result
                                        of the loss of the truck, A must write off the asset that
                                        was destroyed.
                                An entity often maintains insurance to mitigate losses in the event
                of property damage or casualty losses. Even if an asset is insured, the entity would
                recognize a loss to write off the damaged asset and separately recognize any
                recovery. The recognized loss to write off an asset and any associated recovery
                proceeds (through insurance proceeds or other sources of recovery) is treated as two
                separate events and therefore two separate units of account. The principle
                underlying this separation is derived from the involuntary conversion guidance
                codified in ASC 610-30-25-2.
