Set the life and amortization clock

A fifteen-year license can have a six-year useful life. A renewable trade name can have no presently foreseeable limit without being immortal. The schedule starts only after that difference is defended.

Write the life memo before the formula

Inventory the limiting and extending facts: contractual term, renewal options and cost, legal and regulatory limits, expected product dependence, demand, competition, obsolescence, maintenance spending, management's supported use, and the lives of related assets. The shortest supported limit often matters, but no one fact substitutes for the complete analysis.

Classify the asset as finite-lived when the current evidence supplies a limit. Use indefinite-lived only when no foreseeable limit is supported, then retain life reassessment and the applicable impairment path. “Indefinite” never means “ignore the asset until disposal.”

Open the allocation clock

For a finite-lived asset, control cost, residual value, available-for-use date, useful life, and consumption pattern. Linden Peak's $240,000 license is ready April 1, has zero residual value and a supported six-year straight-line life:

$240,000 ÷ 72 months = $3,333.33 per month
$3,333.33 × 9 months = $30,000 first-year amortization
$240,000 − $30,000 = $210,000 ending carrying amount

The calculation retains full precision. A later supported life change is an estimate change applied prospectively; it does not make the original estimate an error. An original schedule that ignored available evidence can be a different accounting question.

Contrast the indefinite lane

Linden Peak's acquired trade name has renewable legal protection, low supported renewal cost, continued expected use, and no current contrary limit. It is not amortized under the supplied classification. The workpaper instead identifies the reassessment date and impairment evidence owner.

Can the schedule be released?

A schedule is ready for release only if a one-page life memo resolves a right whose legal term, expected product life, and renewal evidence point in different directions. State the conclusion, contrary evidence, available-for-use date, method, and the fact that would force reassessment. Then compute only the schedule supported by that memo.
