Apple Inc. has reached a deal with a synthetic sapphire glass maker that will allow details of contracts between the companies and the business problems that led GT Advanced Technologies to a financial crisis to remain secret.

A Tuesday filing in U.S. Bankruptcy Court in New Hampshire shows a settlement that will allow sealed documents filed by GT’s chief operating officer and Apple last week to be withdrawn and all copies destroyed.

Apple hasn’t commented beyond saying it was surprised by the bankruptcy filings and was working to retain jobs at the plant.

GT is shutting down a new sapphire plant in Mesa and laying off 724 workers.

Apple advanced GT $429 million to outfit the plant under a contract announced last November.
