Goodwill has not treated Corporate America so well lately.

Impairment of goodwill—more cynically known as “writing down the value of assets that aren’t worth what you thought”—rose sharply among the S&P 500 last year. Total impairment stood at $30.78 billion, compared to $12.02 billion in 2014. Average impairment among the S&P 500 jumped from $26.4 million in 2014 to $67.7 million last year.

The good news is that only 40 companies in the S&P 500 reported any goodwill impairment at all last year. The bad news: that number is still up 11 percent from 2014, when 36 companies disclosed an impairment charge.

A quick refresher for any non-accountants or analysts reading this post: goodwill is the value places on an asset above its tangible worth. For example, if a software company with $1 million in “hard” assets (computers, property, cash, receivables) is acquired for $10 million, that implies $9 million in goodwill—the value placed on intangible assets such as software patents, customer loyalty, and talented personnel.

Impairment occurs when the company decides (often reluctantly, and after a two-step test to determine impairment) that those intangible assets aren’t worth the stated value. Maybe those patents are invalidated, or long-time customers leave, or employees quit. Suddenly that software company acquired for $10 million is floundering, and that new parent writes down the goodwill value from $9 million to something lower; the exact number depends on just how bad the floundering is.

The mother of all impairments happened in 2003, when Time-Warner took a $45.5 billion impairment on its acquisition of AOL (which Time-Warner had acquired for $103.5 billion just two years earlier). More recently, one of the largest impairments in 2015 happened at Yahoo; it wrote down $4.4 billion in goodwill due to “a combination of factors, including a sustained decrease in our market capitalization in fourth quarter of 2015 and lower estimated projected revenue and profitability in the near term.”

That $4.4 billion was allocated across North America, Latin America, and European operations, plus a separate write-down of $230 million for Tumblr, which Yahoo acquired in 2013 for $1.1 billion, including a press release promising “not to screw it up.”

The next seven companies behind Yahoo, all reporting impairments of $1 billion or more, were in the oil & gas sector—so no surprise there, given how troubled that sector has been with falling oil prices.
