Section I, Traditional Depreciation – Methods for Financial Statement Reporting
Outline 17-1 Calculating Depreciation by the Straight-Line Method Steps to Prepare a Depreciation Schedule by the Straight –Line-Method: Step 1. Determine the total coast and salvage value of the asset. Step 2. Subtract salvage value from total cost to find amount total amount of depreciation. Step 3. Calculated the amount of depreciation by dividing the total depreciation by the useful life of the asset. Step 4. Set up the depreciation schedule in the form of a chart with the following headings: End Annual Accumulated Book of Year Depreciation Depreciation Value

Everybody’s Business Learning Tip On a depreciation schedule, the starting book value is the original cost of the asset, and the last book value is the salvage value of the asset.

17-2 Calculating Depreciation by the Sum-of-Years’-Digits Method
Steps to Prepare a Depreciation Schedule by the um-of-Years’-Digits Method: Step 1. Find the total depreciation of the asset by Step 2. Calculate the SYD depreciation rate fraction for each year by. Total depreciation = Total cost – Salvage value SYD depreciation rate fraction = Years of useful life remaining n (n=1) 2

17-2 Calculating Depreciation by the Sum-of-Years’-Digits Method (Cont
Steps to Prepare a Depreciation Schedule by the um-of-Years’-Digits Method: Step 3. Calculate the depreciation for each year by multiplying the total depreciation by that years’ depreciation rate fraction. Step 4. Set up the depreciation schedule in the form of a chart with the following headings: End of Total Depreciation Annual Accumulated Book Year Depreciation x Rate fraction = Depreciation Depreciation Value Annual depreciation = total depreciation x Depreciation rate fraction

Everybody’s Business Real World Connection From Chapter 15, Financial Statements, remember that depreciation appears on both the balance sheet and the income statement. Balance sheet – Used to determine book value of an asset. Income statement- Listed as an operating expense.

Section II, Asset Cost Recovery Systems – IRS Prescribed Methods for Income Tax Reporting
17-5 Calculating Depreciation by Using the Modified Accelerated Cost Recovery System (MACRS) Steps to Prepare a Depreciation Schedule by Using MACRS: Step 1. Use Table 17-1 to determine the property calss for the asset in question. Step 2. Multiply the cost recovery percentage for each year, from Table 17-2, by the original basis of the asset. Step 3. Set up the depreciation schedule in the form of a chart with the following headings: End of Original Cost recovery Cost recovery Accumulated Book Year Basis Percentage (depreciation) Depreciation Value

Everybody’s Business Learning Tip In MACRS, the entire asset is depreciated. There is no salvage value. Note that the percents for any given property class in the Cost Recovery Percentage table add up to 100%

17-6 Calculating the Periodic Depletion cost of Natural Resources
Steps to Calculate the Periodic Depletion Cost of Natural Resources: Step 1. Compute the average depletion cost per unit by Step 2. Calculate the periodic depletion cost by: Average depletion cost per unit = Total cost of resources – Residual value Estimated total units available Periodic = Units produced in Average depletion depletion current period X cost per unit cost

Chapter 17, Section II Business Decision Intangible Write-offs
As you have seen in this chapter, companies depreciate or write-off the expense of tangible assets, such as trucks and equipment over a period of its useful life. Many companies also have intangible assets that must be accounted for as an expense over a period of time. Intangible assets are resources that benefit the company, but do not have any physical substance. Some examples are copyrights, franchises, patents, trademarks and leases. In accounting, intangible assets are written off in a procedure known as asset amortization. This is much like straight-line depreciation, but there is no salvage value.
