Endo International PLC is letting go of 90 full-time positions as part of a restructuring.

The layoffs will save the company $15 million to $20 million in costs. The restructuring itself is expected to result in $40 million to $50 million in annual run-rate pretax cost savings by the fourth quarter of 2017.

The company will invest the savings in its core product franchises and new product development programs for branded and generics business segments.
