CENTURY 21 ACCOUNTING © 2009 South-Western, Cengage Learning Chapter 8 Objectives Accounting for Uncollectible Accounts After studying Chapter 8, you will be able to: Define accounting terms related to plant assets and depreciation. Identify accounting concepts and practices related to accounting for plant assets and depreciation. Journalize entries for buying plant assets. Calculate and record property tax expense. Calculate and record depreciation expense for a plant asset using straight- line depreciation. Journalize entries disposing of plant assets. Calculate depreciation expense using other methods. 2 LESSON 8-4

CENTURY 21 ACCOUNTING © 2009 South-Western, Cengage Learning Lesson 8-4 declining-balance method of depreciation: multiplying the book value at the end of each fiscal period by a constant depreciation rate sum-of-the-years’-digits method of depreciation: using fractions based on the number of years of a plant asset’s useful life production-unit method of depreciation: calculating estimated annual depreciation expense based on the amount of production expected from a plant asset 3 LESSON 8-4

CENTURY 21 ACCOUNTING © 2009 South-Western, Cengage Learning Lesson 8-4 Modified Accelerated Cost Recovery System: a depreciation method required by the Internal Revenue Service to be used for income tax calculation purposes for most plant assets placed in service after 1986 depletion: the decrease in the value of a plant asset because of the removal of a natural resource 4 LESSON 8-4
