Final answer:
The expenditures on repair and maintenance would be expensed, while extensive repairs that improve asset efficiency or extend its useful life would be capitalized. The net book value of the airplane must account for the original cost, accumulated depreciation, and added value from capital improvements. Depreciation affects net income but does not entail a direct cash outflow and could lower tax payments.
Step-by-step explanation:
Assuming Delta made extensive repairs on an airplane engine, here are the ledger effects for the current year for each transaction:
- Ordinary repairs and maintenance expenditures ($7,000,000 cash) would be expensed in the current period with no effect on the airplane's book value. Therefore, cash would decrease, and repair and maintenance expense would increase, but there would be no effect (NE) on the airplane's capital account.
- Extensive and major repairs to the airplane's engine amounting to $2,700,000 in cash can be capitalized since they increase the asset's efficiency and useful life. Thus, the airplane's asset value on the balance sheet would increase, and cash would decrease by the same amount.
- Recorded depreciation for the current year will depend on the new useful life, remaining book value, and whether any new residual value is considered post repairs.
The net book value of the airplane on December 31 of the current year depends on the new depreciable base (original cost minus accumulated depreciation plus capital improvements) and any depreciation expense recognized during the year.
Regarding the effect of depreciation on cash flows, it's important to note that depreciation is a non-cash expense. Therefore, while it reduces net income for the period, it does not directly result in an outflow of cash. However, the lower net income resulting from depreciation could lead to lower taxable income, which may reduce cash payments for taxes.
