Upon the acquisition of ZF Array on August 31, 2011, the Company accrued $2,400 for contingent consideration. Contingent consideration is based on financial performance of the acquired company’s operations for a 24-month period following the acquisition date, to a maximum of $2,400. The final payment was made in the fourth quarter of 2013, and therefore no additional charges were incurred for the six months ended period June 29, 2014 (June 30, 2013 - $250 loss was recorded as the contingent liability was increased).
