Assuming Anton contribution distribution from Formula (12) Formula (18) defines the annuity depreciation of a single capital investment g as

For t = 1 we have, considering that
= g,

Thus the annuity depreciation
is equal the straight-line depreciation (1/N)g. Likewise, for t = 2
we have

Repeating the process the general
becomes

which, again, is equal the straight-line depreciation.
