Accounting corrections are arguably one of the most important metrics in understanding trends in financial reporting. We can identify three distinct types of error corrections:
- Material errors that undermine reliance on previously filed financial statements. To correct material errors, companies are required to restate previously filed financial statements. The companies are also required to file an 8-K Item 4.02 and warn investors that previously filed financial statements could no longer be relied upon. This type of error correction is also known as a “Big R” restatement.
- Errors that are immaterial to the previously filed financial statements, but that are material in aggregate to the current financial statements. The errors are corrected by revising previously filed financial statements. This type of error correction is also known as a “little r” restatement.
- Errors that are immaterial to either current or previously filed financial statements. The errors are corrected as an aggregate adjustment in the current period, no revision of previously filed financial statements is required. This type of error correction is also known as an out-of-period adjustment.
Big R restatements experienced a steady decline between 2009 and 2016. Out-of-period adjustments, on the other hand, steadily increased over the same period. One possible explanation is that improved internal controls allow for a faster identification of the errors, so the errors are promptly corrected without reaching the level that would necessitate a full-scale Big R restatement.
Let’s take a look at the frequency of the major accounting issues cited for these corrections.
Taxes topped the list of reasons provided for out-of-period adjustments for the last 8 years. In 2016, companies recorded 85 tax related out-of-period adjustments – 26% of all the out of period adjustments recorded during the year. Second and third of the top issues were liabilities (14%) and revenue recognition (12%).
Reasons cited for financial restatements differ significantly from those for out-of-period adjustments. Securities (debt, quasi-debt, warrants & equity) issues ranked at the top, comprising 17.6% of restatements in 2016, whereas these issues were cited in only 5.8% of out-of-period adjustments during the same year. Classification issues was the next most common restatement issue (14.2% of all 2016 restatements).
In addition to issues cited, the most important differentiator between restatements and out-of-period adjustments is materiality, which is governed by SAB 99 (codified into ASC 250). The largest restatement exceed the largest out-of-period adjustment for a majority of the time.
While restatements tend to have a greater negative affect, overlap between restatements and out-of-period adjustments has been shown to exist in a previous research paper as a result of qualitative factors being applied in materiality judgments.
Immaterial errors also carry negative impacts for investor assessments (as shown by share price responses) regardless of the quantitative extent to which it affects financial statements. It appears that this negative connotation to investors stems from the predictive nature of immaterial errors. Whether corrected as a revision or out-of-period adjustment, immaterial errors can be indicative of poor reporting quality which may lead to future material weaknesses and material errors.
