The Boy Scouts of America’s sex abuse settlement plan could fall apart if insurers aren’t granted releases, the financial advisor for the organization’s restructuring testified Monday, the 11th day of a confirmation hearing for the current Chapter 11 plan.

Though those opposing the plan, including insurance companies, have cited a release of future litigation as a primary reason U.S. District Judge Laurie Selber Silverstein of the District of Delaware shouldn’t approve the Boy Scouts’ plan, Brian Whittman of Alvarez & Marshal testified it would be impossible for the plan to be viable without a complete settlement, and a complete settlement is only possible with releases.
