One of the great dangers in allocating common fixed Blank 1 of 1 costs is that such allocations can make a product line look less profitable than it really is.

One of the great dangers in allocating common fixed corporate costs is that such allocations can make a product line look less profitable than it really is.

Explanation:

Therefore, care must be exercised so that a product line is not eliminated because the common fixed costs have been allocated to it such that it becomes unprofitable.  This is why it is necessary to identify activity cost pools into which such fixed costs can be accumulated and from which they can be allocated to product lines.  Using ABC costing approach, for instance, offers a means of escape because the system tries to allocate costs based on the level of usage or consumption of such common costs by each product line instead of using arbitrary allocation formulas.
