This process includes linking all derivatives to specific firm commitments or forecasted transactions and designating the derivatives as cash flow hedges. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative contracts that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items.

Earnings Per Share [Text Block]	12 . Net Loss per Share Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including stock options, restricted stock units and performance share awards, to the extent dilutive. Performance-based performance share awards are considered dilutive when the related performance conditions have been met assuming the end of the reporting period represents the end of the performance period. In periods with a net loss from continuing operations, all potential shares of common stock are excluded from the computation of diluted loss per share as the impact would be antidilutive. Net loss per basic and diluted weighted-average common share outstanding was calculated as follows (in thousands, except per share data): Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Loss from continuing operations $ (5,686 ) $ (1,421 ) $ (7,637 ) $ (4,963 ) Loss on discontinued operations - (647 ) - (973 ) Net loss $ (5,686 ) $ (2,068 ) $ (7,637 ) $ (5,936 ) Basic weighted-average common shares outstanding 9,727 9,610 9,717 9,607 Effect of potentially dilutive common shares (1) - - - - Diluted weighted-average common shares outstanding 9,727 9,610 9,717 9,607 Basic and diluted loss per common share: Continuing operations $ (0.59 ) $ (0.15 ) $ (0.79 ) $ (0.52 ) Discontinued operations - (0.07 ) - (0.10 ) Net loss per share $ (0.59 ) $ (0.22 ) $ (0.79 ) $ (0.62 ) ( 1 The weighted-average number of such antidilutive shares not three six June 30, 2018 64,000 75,000, 40,000 37,000, 100%, not not June 30, 2018. not three six June 30, 2017 195,000 196,000,
