Worked-example setupScope and assumptions
  • Cedar Trail and all facts are fictional and supplied for instruction.
  • The old and new inventory-cost principles are acceptable for the identified population, and an authorized reviewer has supplied a supported preferability conclusion.
  • Full retrospective application is practicable; Years 2 and 3 are comparative periods and Year 2 is the earliest period presented.
  • All effects shown are direct; indirect bonus, royalty, covenant, and cash consequences are excluded and routed separately.
  • A 25 percent enacted tax rate applies to the bounded direct temporary differences with no other tax complication.
  • Weighted-average common shares are supplied and diluted EPS requires a separate period-specific computation.

Problem

Cedar Trail voluntarily changes the inventory-cost principle used for one stable product family. Both methods are acceptable. The authorized technical- accounting reviewer has supplied a preferability conclusion. The controller wants to post the entire cumulative difference to Year 3 income because “that is when we changed the books.” Reconstruct the comparative reporting instead.

The reporting entity and product population are unchanged. That exclusion is part of the route: revising a principle for the same entity is not a change in the entities whose statements are presented.

Partition the historical effects

Years 2 and 3 are presented. Effects before Year 2 are cumulative:

pre-Year-2 pretax inventory increase             $240,000
direct deferred tax liability at 25%              (60,000)
opening Year-2 retained-earnings increase         $180,000

The $180,000 follows from the two balance-sheet adjustments. It enters opening Year 2 equity and never also enters Year 3 income.

Recast Year 2

The new principle increases Year 2 pretax income by $70,000. Under the bounded tax facts, tax expense increases $17,500 and net income increases $52,500.

Year 2 pretax income As reported Adjustment Recast
Amount $620,000 $70,000 $690,000

With 500,000 weighted-average common shares, the basic EPS effect is $0.105, displayed as $0.11. Recompute diluted EPS from the full Year 2 security file; do not assume the basic adjustment is also diluted.

Recast Year 3

The signed Year 3 pretax effect is $(30,000). Tax expense decreases $7,500 and net income decreases $22,500.

Year 3 pretax income As reported Adjustment Recast
Amount $750,000 $(30,000) $720,000

With 520,000 weighted-average common shares, the basic EPS effect is about $(0.0433), displayed as $(0.04). Using Year 2 or current shares would break the period-specific comparison.

Controls and boundary

The asset, deferred-tax, and equity columns must satisfy the accounting equation at the opening of Year 2. Each year's income and tax effects must roll into corrected ending equity. Cash-flow and note effects are rebuilt from the same signed effect ledger.

This example does not prove preferability, practicability, tax law, or diluted- EPS treatment. Those are supplied or separately reviewed. It proves that the accepted route has been partitioned and recomputed without a current-income or retained-earnings plug.
