Item 1.01. Entry into a Material Definitive Agreement.

On January 20, 2016, NOW Inc. (the “Company”) entered into an amendment (the “Amendment”) to its Credit Agreement dated as of April 18, 2014 (the “Credit Agreement”). The Amendment, among other things, (A) suspends, until the Company elects otherwise, the Credit Agreement’s minimum interest coverage ratio effective as of December 30, 2015, (B) adds a minimum asset coverage ratio (as defined in the Credit Agreement), which requires that the ratio of the value of the Company’s eligible assets to the amount of its outstanding obligations under the Credit Agreement is no less than 1.50 to 1.00, (C) reduces the maximum capitalization ratio (as defined in the Credit Agreement) from 50% to 45%, and (D) increases the applicable interest margin on current borrowings by 75 basis points and the current commitment fee by 5 basis points. In connection with the Amendment, the Company also entered into a Security Agreement dated as of January 20, 2016 (the “Security Agreement”) pursuant to which it granted the lenders under the Credit Agreement customary security interests in substantially all of the Company’s U.S. assets and in approximately 65% of the equity interests of the Company’s first-tier foreign subsidiaries.

Total commitments under the credit facility remain at $750 million (provided that borrowings above 75% of such commitments are conditioned upon compliance with a minimum fixed charge ratio (as defined in the Credit Agreement)). The credit facility continues to include the $250 million accordion feature and still expires in April 2019. Based on the Amendment, the Company is in compliance with all financial covenants in the Credit Agreement as of December 31, 2015.

The Amendment and the Security Agreement are filed as exhibits to this current report on Form 8-K.
