You own an oilfield equipment repair shop. You anticipate that in six years your company must spend $75,000 to replace the welding equipment in your shop. Your accountant has your company depreciating its existing equipment on a straight-line basis at rate of $10,500 per fiscal year. You set aside this amount in cash at the end of each year in a bank account that pays interest annually.
