For example, if a business buys a new lathe in October how much of what they paid for it is an offset against their income for that year? All of what they paid, 1/6th of what they paid, 1/60th of what they paid, or some other number?
If a business spends all of their profits to buy new merchandise do they have any income? If so how is it measured - what the inventory cost or what it is worth at the end of the year?
