Apple’s bankrupt former sapphire supplier is seeking to shut down its Mesa, Arizona plant and has informed 727 employees that they will be laid off between today and December 15th, according to AZ Central. The breakdown of the jobs being cut includes:

GTAT first filed for bankruptcy after it was revealed that the company had not been able to meet Apple’s demand for sapphire crystal smartphone displays to be used in the recently-released iPhone 6 and 6 Plus, causing Apple to withhold a #139 million payment.

The sapphire provider has asked that the court documents surrounding this case be sealed and revealed a few of the contractual obligations that Apple’s suppliers are held to. Prior to the announcement, the CEO of GT Advanced Technologies unloaded millions in stock.
