ITEM 2.01 Completion of Acquisition or Disposition of Assets.

On April 4, 2016, Charles River Laboratories International, Inc. (“Charles River” or the “Company”) completed its acquisition of WRH, Inc. (“WRH”), which is now an indirect, wholly owned subsidiary of Charles River.

Under the terms of the Agreement and Plan of Merger, dated January 6, 2016, among Charles River, Pretzel Acquisition Corporation, a wholly owned subsidiary of Charles River (“Merger Sub”), WRH, and American Capital Equity III, LP, in its capacity as Stockholder’s Representative, Merger Sub merged with and into WRH for approximately $585 million in cash, subject to certain customary adjustments. Charles River funded the merger consideration with cash on hand and proceeds from the Seventh Amended and Restated Credit Agreement described below.

ITEM 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On March 30, 2016, Charles River amended and restated its existing credit agreement with certain financial institutions and JPMorgan Chase Bank, N.A., as administrative agent (the “Seventh Amended and Restated Credit Agreement”). The Seventh Amended and Restated Credit Agreement (1) extends the maturity date for the facilities and (2) makes certain other amendments in connection with the Company’s acquisition of WRH. The obligations of Charles River under the Seventh Amended and Restated Credit Agreement are guaranteed by Charles River's material domestic subsidiaries and are secured by substantially all of the assets of Charles River and the guarantors, including a pledge of 100% of the capital stock of the domestic subsidiaries (other than the capital stock of any domestic subsidiary that is treated as a disregarded entity for U.S. federal income tax purposes (“Disregarded Entities”)), and 65% of the capital stock of certain first-tier foreign subsidiaries and Disregarded Entities.

The Seventh Amended and Restated Credit Agreement provides for up to approximately $1.65 billion in financing, including an approximately $650 million term loan facility and a $1 billion revolving facility. Up to the equivalent of $500 million of the revolving facility is available in euros or Sterling to certain subsidiaries of the Company based in the United Kingdom, the Netherlands and Luxembourg (the “Multicurrency Revolving Facility”), and up to the equivalent of $30 million of the Multicurrency Revolving Facility is available in Japanese yen to a subsidiary of the Company based in Japan. The term loan facility matures in 19 quarterly installments with the last installment due March 30, 2021. The revolving facility matures on March 30, 2021, and requires no scheduled payment before that date. Under specified circumstances, the Company has the ability to increase the term loans and/or revolving line of credit under the Seventh Amended and Restated Credit Agreement by up to $500 million in the aggregate. The interest rates applicable to term loans and revolving loans under the credit agreement are, at the Company’s option, equal to either the base rate (which is the higher of (1) the prime rate, (2) the federal funds rate plus 0.50%, or (3) the one-month adjusted LIBOR rate plus 1%) or the adjusted LIBOR rate plus an interest rate margin based upon the Company’s leverage ratio.

The interest rates applicable to term loans and revolving loans under the Seventh Amended and Restated Credit Agreement are lower than the interest rates under the existing facilities, reflecting current market conditions.

In addition to the scheduled repayments, Charles River is required to prepay the term loans with the following amounts:

The Seventh Amended and Restated Credit Agreement requires that Charles River comply with an interest coverage ratio test and a leverage ratio test. In addition, the Seventh Amended and Restated Credit Agreement includes negative covenants that will, subject to significant exceptions, limit the ability of Charles River and its subsidiaries to:

The Seventh Amended and Restated Credit Agreement also contains certain customary representations and warranties, affirmative covenants, and events of default.

The Seventh Amended and Restated Credit Agreement is attached hereto as Exhibit 10.1 and incorporated into this Item 2.03 by reference.

ITEM 7.01 Regulation FD Disclosure.

On April 4, 2016, Charles River issued a press release announcing the completion of the acquisition. A copy of the press release is attached hereto as Exhibit 99.1. The information being furnished pursuant to Item 7.01, including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall it be deemed incorporated by reference into any filing under the Securities Act of 1933, except as expressly set forth by reference in such filing.
