The assignment involves understanding and comparing the periodic and perpetual inventory systems, particularly focusing on their impact on calculating the cost of goods sold (COGS), their use in financial statements, and related accounting considerations. It includes assessing how inventory is recorded, how costs are determined, understanding FOB points, purchase discounts, purchase returns, and different cost flow assumptions. Additionally, it explores methods for computing ending inventory, industry usage, and factors influencing method choice. The assignment emphasizes understanding the LIFO conformity rule, cost index calculations, dollar-value LIFO, inventory valuation approaches like LCNRV or LCM, and handling inventory write-downs. It also covers inventory estimation techniques, the implications of changing inventory methods, prior period errors, and the recording of PPE, intangible assets, goodwill, and asset retirement obligations. The task extends to journal entries for various transactions, calculation of depreciation, depletion, amortization, impairment, and the handling of material errors, changes in estimates, and different depreciation methods. It discusses the recording of gains or losses from asset exchanges, the treatment of R&D costs, and the impact of impairment assessments. Overall, the focus is on comprehensive knowledge of inventory and fixed asset accounting, including theoretical concepts, practical computations, and GAAP compliance.

Paper For Above instruction

Understanding the distinctions between the periodic and perpetual inventory systems is foundational for accurate financial accounting and reporting. Both systems aim to track inventory costs and quantities, yet they differ significantly in methodology, timeliness of updates, and implications for financial statements. In this comprehensive analysis, we explore the fundamental aspects of each system, their respective treatments of the cost of goods sold (COGS), inventory valuation, and their alignment with industry practices and regulatory requirements.

Periodic vs. Perpetual Inventory Systems

The periodic inventory system updates inventory counts and COGS at specific intervals, typically at the end of an accounting period. Inventory purchases are recorded in a Purchases account, and COGS is calculated after an end-of-period physical count of inventory (Coulson & Taylor, 2020). Conversely, the perpetual inventory system maintains ongoing updates to inventory records with each purchase and sale, utilizing technology such as barcoding or RFID. This system provides real-time data, facilitating timely decision-making and inventory management (Warren et al., 2019).

Cost of Goods Sold and Financial Statements

The COGS is a crucial figure on the income statement, reflecting the direct costs attributable to goods sold during a period. Under the periodic system, COGS is derived after adjusting beginning inventory with purchases and ending inventory calculated through physical counts. It appears on the income statement and affects gross profit (Kieso et al., 2021). In the perpetual system, COGS is updated instantly with each sale, providing more accurate and timely financial insights.

Recording Inventory and Cost Flows

Inventory enters the accounts through purchase transactions, which may be influenced by FOB points—FOB shipping point and FOB destination—that determine when ownership transfers. Purchase discounts are recorded when taken, reducing the purchase cost, typically as a reduction of inventory or as a separate contra-expense account (Gordon et al., 2017). Purchase returns, similar to discounts, decrease inventory and impact cost calculations.

Cost Flow Assumptions and Valuation

Common cost flow assumptions include FIFO (First-In, First-Out), LIFO (Last-In, First-Out), average cost, and specific identification. These assumptions influence the computation of ending inventory and COGS. For instance, FIFO assumes older inventory costs are expensed first, often aligning with physical flow, though not always. LIFO assumes newer inventory is sold first, which affects tax liabilities and financial ratios. Industries such as retail often favor FIFO for simplicity, while oil and gas industries might prefer LIFO due to inventory characteristics (Horngren et al., 2018).

Matching Inventory Method to Actual Flow & LIFO Conformity Rule

Choosing an inventory method involves considering actual physical flow and consistency with financial reporting. The LIFO conformity rule mandates that if a company uses LIFO for tax purposes, it must also report inventory using LIFO for financial statements, which may differ from physical inventory flow (Higgins & Marshall, 2017).

Cost Index and Dollar-Value LIFO

A cost index, typically based on a price or cost index for a base year, is used to adjust inventory layers in dollar-value LIFO calculations. This method values inventory at current prices, focusing on dollar value rather than physical quantities. It simplifies inventory management, especially when quantities fluctuate, and helps prevent erosion of layers due to price increases (Fowler & Rittenberg, 2016).

Inventory Valuation Techniques and Write-downs

Inventory valuation may employ LCNRV (lower of cost or net realizable value) or LCM (lower of cost or market). When inventory declines below cost, a write-down to NRV is recorded, reflecting a loss in value. Common write-downs are usual, whereas unusual or significant declines require additional disclosures. Companies must support this adjustment with documentation (Schroeder et al., 2018).

Inventory Estimation & Method Switching

Estimation techniques like gross profit method and retail inventory method are used for interim or analytical purposes. Switching inventory methods necessitates proper documentation and may require retrospective adjustments to prior periods’ financial statements to ensure consistency (Brigham & Ehrhardt, 2017).

Handling Inventory and Asset Errors

Material errors discovered in prior periods are corrected retrospectively, adjusting prior financial statements and opening balances. Minor errors or changes in estimates, such as depreciation rates, are accounted for prospectively (Kieso et al., 2021).

Cost of PPE & Intangible Assets

Initial costs include the purchase price, taxes, transportation, and installation. Goodwill is computed as the excess of purchase price over the fair value of identifiable net assets. Asset Retirement Obligations (AROs) are recognized when a legal obligation exists, with initial costs included in the asset’s capitalized amount (Henderson & Rudd, 2019). Some intangible assets, like goodwill, are not amortized but tested annually for impairment.

Accounting for Acquisitions and Transactions

Assets acquired through noncash transactions are recorded at fair value. Donated assets are recorded at fair value as contributions revenue and the corresponding asset. Gains or losses from asset sales are computed as the difference between sale proceeds and book value, recognized in income (Louwers et al., 2020). When trading in equipment, the fair value of the new asset and the old asset’s book value determine the gain or loss. Software development costs are capitalized when they meet specific criteria, otherwise expensed (Hoffman et al., 2019).

Depreciation, Depletion, and Amortization

Depreciation allocates the cost of Tangible Assets over their useful lives; depletion pertains to natural resources; amortization relates to Intangible Assets. The depreciation method chosen, such as straight-line or declining balance, affects expense recognition. Changes in estimates are handled prospectively; modifications in depreciation methods follow specific GAAP rules (Schroeder et al., 2018).

Impairment and Material Errors

Impairment testing involves a two-step process to assess whether an asset’s carrying amount exceeds its recoverable amount, recognizing an impairment loss if necessary. Material errors require correction in prior period financial statements, with full disclosures of the impact (Henderson & Rudd, 2019).

Capitalization vs. Expense & Transaction Entries

Expenditures that extend the useful life or improve an asset are capitalized; routine maintenance is expensed. Journal entries for purchases, depreciation, inventory, and asset disposals follow standard accounting procedures, reflecting increases or decreases in respective accounts (Warren et al., 2019).

Conclusion

Effective management of inventory and fixed assets requires understanding multiple accounting principles, proper application of cost flow assumptions, and compliance with GAAP standards. Companies must choose appropriate methods based on industry practices, physical flow of goods, and regulatory requirements, ensuring accurate financial reporting and operational efficiency.
