Depreciation can mislead one on net income. Let's say one year you make $5,000,000 in net income. You have a comprehensive income (change) of $1,000,000. Your total of $6,000,000 in net income. BUT, you spent $7,000,000 on expansion (credit from the bank) which increase your interest payments each month (expenses), and you depreciation expense (tax deductable) goes up to $3,000,000 for the year (at the now acceptable accelerated rate allowed). Your interest payments at 8% annualy would be $560,000 plus depreciation expense of $3m, equals $3.56 mill off your net income, which leaves only $2,440,000 net income, BUT you expanded from 5 stores to 15 stores. Revenues are key here, not necessarily net income.
