Equity Method Investments and Joint Ventures [Abstract] |
VENTURE CAPITAL INVESTMENTS | VENTURE CAPITAL INVESTMENTS The Company invests in several venture capital funds that invest in start-up companies, primarily in the life sciences industry. The Company’s ownership interest in these funds ranges from 0.7% to 12.0%. The Company accounts for the investments in limited partnerships (LPs), which are variable interest entities, under the equity or cost method of accounting. The Company is not the primary beneficiary because it has no power to direct the activities that most significantly affect the LPs’ economic performance.

The Company’s total commitments to the entities as of April 1, 2017, were $84.8 million, of which the Company funded $42.0 million through April 1, 2017. During the three months ended April 1, 2017, the Company received dividends of $4.4 million from the entities. During the three months ended March 26, 2016, the Company received no dividends from the entities. The Company recognized a gain of $4.2 million and a gain of $3.1 million related to these investments for the three months ended April 1, 2017, and March 26, 2016, respectively.
