Material Impairments Reported to the SEC
Form 8-K filings reporting a material impairment charge, all SEC filers and S&P 500 companies, 12-month totals
Plays the chart through its history. Pauses are where the data set a record or moved most.
Original Form 8-K filings by every SEC registrant, counted by filing date; amendments are not counted and a filing made jointly by a parent and its subsidiaries counts once. Private companies do not file 8-Ks. S&P 500: the index list as it stood on 26 September 2026 for earlier years, dated membership since.
Companies writing down goodwill, intangibles or other assets outside their regular reports. Impairments cluster after downturns and sector shocks.
