                                         Depreciation The amount of expense that a company
                                         charges against earnings to write off the cost of a capital
                                         asset over the time it will benefit the company, without
                                regard to how it was paid for and after coinsidering age, wear, obsoles-
                                cence, and salvage value.
                                  There are various methods of calculating this expense, most origi-
                                nating from favorable tax laws. If the expense is assumed to be
                                incurred equally over the life of the asset, the method of depreciation
                                is straight line. If the expense is assumed to be incurred in decreasing
                                amounts over the life of the asset, the method is accelerated.The
                                straight line method is more common: the total cost of the asset is
                                divided by the number of months it will be used and the result is
                                charged to expense each month until the asset is retired or sold off.
                               cash payments and the periods benefited more into alignment.
                               It might finance a machine over five years and depreciate it
                               over the same five years. For many assets, this is helpful but
                               doesn’t solve the problem entirely, as financing periods are
                               often shorter than the useful lives of the assets being financed,
                               e.g., a factory machine might last seven to 10 years or more,
                               yet few banks will finance such purchases for longer than three
                               to five years. Thus, even in this seemingly ideal scenario, you
                               will still have a disparity between the cash disbursement and the
                               recording of depreciation expense.
                                   Another example is the area of prepaid expenses (discussed
                               in Chapter 3), which are amortized. An example might be an
                               insurance policy on which an annual premium is paid in
                               advance. When you buy insurance and pay the premium, that
                               policy provides protection for a year. Proper accounting treat-
                               ment says that the premium benefits all 12 months and should
                               therefore be charged to profits over the benefit period, not just
                               the month in which you paid the premium. So, you write your
                               check in January 2003, but you record as expense only 1/12 of
                               the check amount each month during the next 12 months, the
                               period of coverage. Cash flow and expense are reflected totally
                               differently in this example.
                                   As you can see, some of these examples describe transac-
