4. Accrued contingent consideration

In connection with the acquisition of substantially all of the assets of Printrex, Inc. (“Printrex”) on August 19, 2011, we entered into a contingent consideration arrangement for 30% of the gross profit for a three-year period related to certain new products under development, less certain other adjustments, beginning on the earlier of 1) January 1, 2012 or 2) the date of first commercial introduction of the new products under development.  The undiscounted fair value related to the contingent liability could range from approximately $200,000 to $1,600,000.  The fair value of the contingent consideration arrangement was $760,000 and $960,000 at June 30, 2013 and December 31, 2012, respectively, which was estimated by applying the income approach.  That measure is based on significant inputs that are not observable in the market, which fair value measurement guidance refers to as Level 3 inputs. During the second quarter of 2013, the fair value of the contingent consideration decreased by $200,000 and this credit is included in general and administrative expenses on the Condensed Consolidated Statements of Income.No payments were made under the arrangement during the six months ended June 30, 2013 as the underlying conditions of the contingent consideration arrangement were not satisfied. Refer to Note 3, Business acquisitions, to the Company’s Consolidated Financial Statements included in the Company’s 2012 Annual Report on Form 10-K for the year ended December 31, 2012 for additional information regarding this contingent consideration arrangement.
