INCOME TAXES	INCOME TAXES The Company’s effective tax rate for the three months ended March 31, 2018 and April 1, 2017 was 15.5% and 39.8%, respectively. For the three months ended March 31, 2018, the decrease was primarily attributable to the tax on the gain on the divestiture of the CDMO business of $18.0 million in the first quarter of 2017 and tax benefits from favorable taxing authority rulings for the three months ended March 31, 2018 of $2.7 million.

The amount of accrued interest on unrecognized tax benefits was $2.6 million at March 31, 2018.
