When shares of Chipotle Mexican Grill Inc. peaked on Aug. 5, 2015, four top executives held stock appreciation rights worth $225 million. For now, they’re worthless.

A plunge of more than 60 percent since then has erased paper gains of $37.5 million for Chief Executive Officer Steve Ells, $34.8 million for Chief Financial Officer Jack Hartung and $10.7 million for Chief Marketing Officer Mark Crumpacker.

Montgomery Moran, who left the company in June after sharing the CEO job with Ells, may have taken the biggest hit. His awards were worth $142.1 million at the 2015 peak, when the shares closed at $757.77. It’s unclear whether he exercised any of the securities this year.

Stock appreciation rights are similar to stock options as they generate gains when they’re exercised above the strike price. The awards held by the four men have strike prices ranging from $318.45 to $543.20. Chipotle shares tumbled 15 percent to $276.02 at 11:41 a.m. in New York, a day after the company reported a profit that badly missed Wall Street estimates.
