Material Impairment 8-Ks, Trailing 12 Months (S&P 500)

## What this measures

The total over the latest 12 months of original Form 8-K current reports in which a company's board or officers conclude that a material charge for the impairment of an asset (goodwill, intangibles, property, investments) is required: filings that list Item 2.06 (Material Impairments), filed while the company was an S&P 500 member. Counted by filing date, monthly, from September 2004, the first full month of the current 8-K item regime.

## Why it matters

A Form 8-K is due within four business days of the event, so these counts move ahead of quarterly reports and court statistics. Impairment charges are asset values written down after the fact: they cluster after a downturn, a sector shock or a failed acquisition, and tend to lag the cycle.

## How to read it

Higher means more filings. The 12-month total smooths out the month-to-month noise of a small count; compare it with the same month a year earlier. The count also moves with the number of companies that report to the SEC, which changes over time, so compare levels across decades with care. The S&P 500 series is much smaller than the all-filer count and can be zero for long stretches.

## What it does not say

It counts filings, not companies or dollars: a company can report an event in more than one filing, and a filing says nothing about the size of the debt or charge. Only SEC registrants file 8-Ks, so private companies (most borrowers) are not here, and companies that stopped reporting before a default are missed. A filing filed jointly by a parent and its subsidiaries counts once. Amended reports (8-K/A) are not counted. Asset-backed securities issuers (SIC 6189) and filers with no industry code are left out: in 2005–2007 several hundred note-issuing trusts of two life insurers filed 8-Ks tagged Item 1.03, which would otherwise double those years' bankruptcy counts. S&P 500 membership comes from Palanor's membership table: companies in the index before 26 September 2026 count for their whole history (the list as it stood then, so companies that left the index earlier are missing and failures are under-counted); dated changes count from that day.
