Item 1.01. Entry into a Material Definitive Agreement

New Asset Based Revolving Credit Facility

Overview

On February 11, 2016, SunOpta Inc. (the “Company”), SunOpta Foods Inc. (“SunOpta Foods”), The Organic Corporation B.V. (“TOC”) and certain other subsidiaries of the Company entered into a new $350.0 million asset-based revolving credit facility (the “New Asset-Based Revolving Credit Facility”) consisting of (x) a U.S. asset-based revolving credit subfacility in an initial aggregate principal amount of up to $260,000,000 (the “U.S. Subfacility”), (y) a Dutch subfacility in an aggregate principal amount of up to $75,000,000 (the “Dutch Subfacility”) and (z) a Canadian subfacility in an aggregate principal amount of up to $15,000,000 (the “Canadian Subfacility”). The New Asset-Based Revolving Credit Facility allows the borrowers to request that lenders provide additional commitments and/or borrowings of up to $100.0 million, subject to customary borrowing conditions and the agreement of any such lenders to provide such commitments.

The Company and certain of its Canadian subsidiaries are the borrowers under the Canadian Subfacility (the “Canadian Borrowers”), SunOpta Foods and certain of its subsidiaries are the borrowers under the U.S. Subfacility (the “U.S. Borrowers”) and TOC and certain of its Dutch subsidiaries are the borrowers under the Dutch Subfacility (the “Dutch Borrowers” and, together with the Canadian Borrowers and the U.S. Borrowers, the “Borrowers”). Borrowings under the New Asset-Based Revolving Facility may be made in U.S. Dollars, Canadian Dollars, Euros, Pounds Sterling, Swiss Francs and such other currencies as may be agreed by the Company and the lenders.

The New Asset-Based Revolving Credit Facility includes borrowing capacity available for letters of credit and provides for borrowings on same-day notice including in the form of swingline loans. A portion of the proceeds of the New Asset-Based Revolving Credit Facility will be used to repay in full the amounts owing under (i) the seventh amended and restated credit agreement dated as of July 27, 2012, as amended, supplemented or otherwise modified from time to time (the “North American Credit Facility”), and (ii) the amendment and restatement agreement, dated October 14, 2014, relating to that certain €92,500,000 Multipurpose Facilities Agreement, originally dated September 25, 2012, as amended, supplemented or otherwise modified from time to time (the “European Credit Facility”).

Interest Rate and Fees

Borrowings under the New Asset-Based Revolving Facility will bear interest at a margin over a reference rate selected at the option of the relevant Borrower. The margin for the New Asset-Based Revolving Credit Facility will be set quarterly based on average borrowing availability for the preceding fiscal quarter and will range from 0.25% to 0.75% with respect to base rate and prime rate borrowings and from 1.25% to 1.75% for eurocurrency rate and bankers’ acceptance rate borrowings. The initial margin for the New Asset-Based Revolving Credit Facility is 0.50% with respect to base rate and prime rate borrowings and 1.50% with respect to eurocurrency rate and bankers’ acceptance rate borrowings.

In addition to paying interest on outstanding principal under the New Asset-Based Revolving Credit Facility, the Borrowers are required to pay an unused line fee to the lenders under the New Asset-Based Revolving Credit Facility in respect of the unutilized commitments thereunder. The initial commitment fee rate is 0.30% per annum. The commitment fee rate is subject to a step-down based upon average utilization of the New Asset-Based Revolving Credit Facility commitments. The Borrower is also required to pay customary letter of credit fees, to the extent letters of credit are issued and outstanding under the New Asset-Based Revolving Credit Facility.

Guarantee and Security

All obligations under the New Asset-Based Revolving Credit Facility are unconditionally guaranteed by (x) each Borrower (other than with respect to its own obligations) and (y) each existing and future direct and indirect wholly-owned domestic, Canadian or Dutch subsidiary of the Company (other than the Borrowers, any immaterial subsidiaries, unrestricted subsidiaries, subsidiaries that are precluded by law or regulation from guaranteeing the obligations and other customary exceptions) (the subsidiaries described in this clause (y), collectively, the “Subsidiary Guarantors”).

In addition, the New Asset-Based Revolving Facility is secured by a first priority security interest in (x) substantially all of tangible and intangible assets of the Borrowers and those of each of the Subsidiary Guarantors (subject to certain customary exceptions and qualifications) and (y) all the capital stock of, or other equity interests in, each Borrower (other than the Company) and each Borrowers’ and each Subsidiary Guarantors’ direct restricted subsidiaries (subject to certain customary exceptions and qualifications) (collectively, the “Collateral”).

Certain Covenants and Events of Default

The New Asset-Based Revolving Credit Facility contains a number of covenants that, among other things, restrict, subject to certain exceptions, the Company’s, and the Company’s restricted subsidiaries’ ability to:

In addition, the Company and its restricted subsidiaries are required to maintain a minimum fixed charge coverage ratio of 1.0 to 1.0 if excess availability is less than the greater of (x) $20.0 million or (y) 10% of the lesser of (1) the aggregate commitments under the New Asset-Based Revolving Credit Facility and (2) the aggregate borrowing base until the 30th consecutive day that excess availability exceeds such threshold.

The New Asset-Based Revolving Credit Facility also contains certain customary affirmative covenants and events of default.
