Its a method of calculating depreciation.  Its a ratio of the
years of life expectancy in reverse order to the sum of those
digits.  For example, if the life expectancy is three years:

    (3+2+1)/6

The depreciation in the first year is 3/6, in the second year 2/6
and the third year is 1/6.

The formula

   S=(N*(N+1))/2

may be used to find the denominator.

For financial info I use

  "Financial Management" by Siegel and Shim

a part of the Barron's Business Library
