Granite Harbor failed to accrue $20,000 of an operating obligation in each of 4 years. Nothing reversed. At the end of Year 4, the liability is understated by $80,000 and current-year pretax income is overstated by $20,000.

rollover amount:      current Year 4 income overstatement      $20,000
iron-curtain amount:  ending liability understatement          $80,000

Both are correct answers to different questions. Neither is the materiality conclusion.

Compute one signed error ledger

Start with origin, reversal, correction, and carryover by period:

Year Origin increases reported income Reversal decreases reported income Correction through income Rollover Ending accumulated liability understatement
1 $20,000 $0 $0 $20,000 $20,000
2 20,000 0 0 20,000 40,000
3 20,000 0 0 20,000 60,000
4 before correction 20,000 0 0 20,000 80,000

If management proposes an $80,000 Year 4 expense catch-up, ending liabilities become correct, but the proposed current-income correction exceeds the current rollover amount by $60,000. That out-of-period component needs its own supplied reporting conclusion.

For a reversing error, the relationship can invert. A $75,000 prior-year overstatement that reverses this year can produce a $75,000 current rollover effect and a zero ending iron-curtain amount after reversal. Neither approach is uniformly larger or more conservative.

Aggregate without hiding gross effects

Maintain a passed-adjustment schedule with:

  • identifier, owner, discovery and origin dates;
  • account, statement caption, business unit, and period;
  • current origin, reversal, correction, and ending carryover;
  • pretax, tax, after-tax, and EPS views;
  • rollover and iron-curtain quantities;
  • gross and permitted analytical net views;
  • qualitative facts and affected controls; and
  • corrected, passed, unresolved, or superseded status.

Two errors can offset net income while distorting revenue and expense, current and noncurrent classification, segments, ratios, or trends. Preserve gross effects and the reason for any aggregation or net presentation.

Perform the separate SAB 99 analysis

Magnitude is a starting point. The supplied materiality file also considers the actual surrounding facts, including whether a misstatement masks a trend, changes a loss to income, affects a segment, changes contract or regulatory compliance, changes compensation, concerns concealment or unlawful activity, or combines with other items.

Do not use 5 percent, or any percentage, as a safe harbor. Do not turn one qualitative example into an automatic materiality override. Record contrary evidence and the responsible conclusion. The accounting exercise can show the inputs and their consequences without pretending that a formula decides what a reasonable investor would consider important.

Preserve scope

SAB 99 and SAB 108 express SEC staff views for covered registrants. They are not Commission rules and do not become general GAAP for every private company. The initial SAB 108 transition accommodation is historical, not a recurring option. The course uses the two-view framework only in an explicitly scoped registrant extension and keeps Topic 250 classification separate.

The quantitative phase closes when both views reconcile to one error ledger, the proposed booking is tested for current distortion, gross and aggregate views remain visible, and the supplied materiality conclusion is documented without a mechanical threshold.
