Billionaire collector Ronald Perelman's $410 million insurance trial has finally begun after seven years of litigation, over 1,500 court filings, and a 2018 fire at his East Hampton estate. The dispute centers on five paintings by Cy Twombly, Ed Ruscha, and Andy Warhol that survived the fire but were exposed to smoke and sprinklers. Perelman claims the works lost their market appeal—their "oomph"—while insurers at Lloyd's of London dispute any detectable damage and allege Perelman quietly tried to sell some of the pieces. The trial has also revealed that Perelman sold over 70 works from his collection after a margin call from Deutsche Bank, with some contested paintings used as collateral.
This case matters because it highlights a persistent challenge in the art market: how to quantify intangible aesthetic losses, or "oomph," in insurance claims. The legal battle draws on scientific testimony about invisible chemical degradation, echoing past disputes like the overpainting of a vandalized Barnett Newman in the 1990s and the restoration controversies around Leonardo da Vinci's *Salvator Mundi*. The trial also exposes the intersection of art collecting with high finance, as Perelman's financial arrangements and margin calls come to light, underscoring how art assets are increasingly treated as collateral and how valuation disputes can drag on for years, with rising legal costs and calcifying positions.
