Build the retrospective comparative bridge

Partition pre period and presented period direct effects, then reconcile opening equity, statements, tax, and per share amounts without plugs or duplication.

The authorized preferability file is complete. Cedar Trail now has to show what each comparative statement would have reported under the new principle. The work begins with a time boundary, not a retained-earnings number.

Partition the years

Assume Cedar Trail presents Years 2, 3, and 4. The model has historical records for Years 0 through 4. The opening of Year 2 is the comparative boundary.

Layer	Treatment
Year 0 and Year 1 direct effects	cumulative after-tax adjustment to opening Year 2 assets, liabilities, and equity
Year 2 direct effects	revise Year 2 statement lines, tax, income, and EPS
Year 3 direct effects	revise Year 3 statement lines, tax, income, and EPS
Year 4 direct effects	apply the new principle in current-year columns
indirect effects	recognize when incurred under their own facts

The earliest period presented is not the oldest year in the ledger. Records before Year 2 still matter, but their cumulative direct effect enters the opening balances of the earliest presented period rather than a phantom fourth comparative income statement.

Derive opening equity from accounts

For a supplied pre-Year-2 pretax asset increase of $240,000 and a 25-percent direct tax effect:

asset adjustment                              $240,000
deferred tax liability                         (60,000)
opening retained-earnings increase             $180,000

The $180,000 follows from the asset and tax balances. It appears in the opening balance sheet and statement of changes in equity; it does not also pass through Year 4 income. If the asset and liability effects do not explain the equity amount, investigate the missing account rather than force a plug.

Build period-specific direct effects

Use signed as-reported, adjustment, and recast columns for each statement line. For example:

Year 2 line	As reported	Adjustment	Recast
Cost of goods sold	$4,800,000	($70,000)	$4,730,000
Pretax income	620,000	70,000	690,000
Income tax expense	155,000	17,500	172,500
Net income	465,000	52,500	517,500

The signs depend on the displayed line: a negative COGS adjustment increases pretax income. State that convention at the top of the workpaper. Recompute each period's current and deferred tax consequences and basic and diluted EPS from that period's facts; do not carry one rate or share count across columns.

Reconcile every statement

The balance-sheet adjustment columns must satisfy assets equals liabilities plus equity. Recast ending retained earnings must roll from recast opening equity, recast net income, dividends, and other equity movements. Cash-flow classification and the indirect reconciliation must agree with recast income and balances even when total cash is unchanged.

The note then explains the nature and reason, preferability, method, periods and line items recast, per-share effects, and opening-equity adjustment. The bridge is ready for disclosure only when each period and statement ties independently.
