| Accumulated Depreciation | Contra-Asset (+) | - | 500.00 |
💡 Accountant's Note
Unlike a delivery truck, factory machine depreciation is a component of product cost (Overhead).
Practitioner & Systems Framework
💻 ERP Architecture
Factory machine depreciation flows through Manufacturing Overhead (not directly to the P&L as an expense) because it is a production cost — it is embedded in the product cost and recognized as COGS when goods are sold. Administrative asset depreciation (office computers, sales vehicles) goes directly to SG&A. Use the units-of-production depreciation method for high-use factory machines where production volume directly drives wear — this produces a more accurate unit cost. For straight-line depreciation, the monthly charge = (Cost − Residual) ÷ Useful Life in months.
⚠️ Audit Flags
Auditors confirm the depreciation method and useful life are appropriate for each asset type. Production equipment useful lives should be reviewed annually — early obsolescence (due to technology changes or product line discontinuation) may require impairment testing. For the fixed asset register, confirm factory equipment is correctly categorized (production, not administrative) to ensure depreciation flows to the correct account.
📄 Required Documentation
Fixed asset register (equipment type, cost, residual value, useful life, depreciation method, category — factory vs. admin), monthly depreciation calculation, Manufacturing Overhead (Control) posting, Accumulated Depreciation update, useful life review memo, impairment assessment (if production equipment is obsolete or underutilized), and component accounting records (for multi-component equipment).
