Book Notes

Cost basis - of an asset represents the total cost that is claimed as an expense over an asset's life. in other words its the sum of the annual depreciation expenses.

Two Depreciation Methods

  1. 1. Book - intended for financial reports, such as income statements and balance sheets. Uses Straight Line calculation.
\begin{equation} Dn=(I-S)/N \end{equation}

Dn = Depreciation charge
I = Cost of the asset including installation expenses.
S = Salvage value at the end of the useful life
N = Useful life

  1. 2. Tax - for the purpose of calculating taxes. Uses the Modified Accelerated Cost Recovery System(MACRS). Under MACRS the salvage value is zero. It is broken up into 8 recovery periods; 3, 5, 7, 10, 15, 20, 27.5, 39 year.
