NOTES	Depreciation is an estimate, and it is permissible to change the depreciation,
	as long as the change is prospective (in the future). So, a company might
	depreciate an asset for a few years, and then decide that the asset will last
	longer or shorter. The company is not allowed to go back to previous years
	to change the depreciation, but can speed up or slow down the depreciation
	in the future.
RULE	To change the depreciation, take the remaining BOOK VALUE, subtract the
	SALVAGE VALUE, and divide the result by the REMAINING YEARS.
	Although we are concentrating on a change in the LIFE of the asset, the
	SALVAGE VALUE may also be changed.
