Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Note 7- Commitments and Contingencies Under the terms of the Amega Agreement, we are required to pay contingent consideration (the “Amega Earn Out”) if the cumulative revenues for our Continuous Monitoring Division for the three years subsequent to the acquisition meet certain levels. The potential consideration payable ranges from $0 to $10,000,000 and is based upon a sliding scale of three-year cumulative revenues between $31,625,000 and $43,500,000. Based upon both historical and projected growth rates, we recorded $500,000 of contingent consideration payable which represents our best estimate of the amount that will ultimately be paid. Any changes to the contingent consideration ultimately paid will result in additional income or expense in our condensed consolidated statements of income. We will continue to monitor the results of our Continuous Monitoring Division and we will adjust the contingent liability on a go forward basis, based on then current information. The contingent consideration is payable in the third quarter of our year ending March 31, 2017. In November 2014, Amega Scientific Corporation (“Amega”) and its owner Anthony Amato (“Amato”) filed a complaint in the United States District Court for the district of Colorado alleging, among other items, that our termination of Amato as an employee impacted his ability to maximize the potential consideration payable under the Amega Earn Out and to exercise stock options that failed to vest. In addition, Amato has alleged that we improperly withheld certain amounts from the holdback consideration under the Amega Agreement. These amounts (which were recorded as liabilities in our original purchase accounting) remain recorded as other accrued expenses on the accompanying condensed consolidated balance sheets and will remain so until a final ruling by the court is made. In January 2015 we filed a motion to dismiss the complaint with prejudice. Given that the complaint is in the early stages of the process, we are unable to make a reasonable estimate of the potential loss or range of losses, if any, that might arise from this matter. We believe that we acted in a matter consistent with employment law and the provisions of the Amega Agreement and we intend to defend our position vigorously. Under the terms of the Bios Agreement, we are required to pay contingent consideration if the cumulative revenues related to the acquisition for the three years subsequent to the acquisition exceed $22,127,000. The potential future payment that we could be required to make ranges from $0 to $6,710,000. Based upon historical growth rates, we initially recorded $2,140,000 of contingent consideration payable which represented our best estimate of the amount that would ultimately be paid. Based upon actual results and current run rates, during the year ended March 31, 2014, we revised our estimate of the ultimate contingent liability that would be paid, which resulted in reducing the contingent consideration payable to $1,120,000. Any further changes to the contingent consideration ultimately paid would result in additional income or expense in our condensed consolidated statements of income. We will continue to monitor the results associated with the Bios Acquisition and we will adjust the contingent liability on a go forward basis, based on then current information. The contingent consideration is payable in the first quarter of our year ending March 31, 2016. Under the terms of the PCD Agreement, we are required to pay contingent consideration if the cumulative revenues for our process challenge device business for the three years subsequent to the acquisition meet certain levels. The potential consideration payable ranges from $0 to $1,500,000 and is based upon a sliding scale of three-year cumulative revenues between $9,900,000 and $12,600,000. Based upon both historical and projected growth rates, we recorded $300,000 of contingent consideration payable which represents our best estimate of the amount that will ultimately be paid. Any changes to the contingent consideration ultimately paid will result in additional income or expense in our condensed consolidated statements of income. We will continue to monitor the results of our process challenge device business and we will adjust the contingent liability on a go forward basis, based on then current information. The contingent consideration is payable in three annual installments beginning in the third quarter of our year ending March 31, 2016. A company is required to collect and remit state sales tax from certain of its customers if that company is determined to have “nexus” in a particular state. The determination of nexus varies state by state and often requires knowledge of each jurisdiction’s tax case law. During the year ended March 31, 2013, we determined that there are states in which we most likely had established nexus during prior periods without properly collecting and remitting sales tax. We recorded an estimate of $100,000 associated with one specific state but we were unable to estimate our remaining exposure at that time. The ultimate amount due in remaining states will depend upon a number of factors, including the amount of sales that were made to customers who are either exempt or have already paid the tax, the number of years of exposure, and any penalties or interest that might be due. During the year ended March 31, 2014, we completed our analysis associated with the remaining states and we recorded an estimate of $1,408,000, which was included in other accrued expenses on the consolidated balance sheets and in general and administrative expense on the consolidated statements of income for the year ended March 31, 2014. That estimate was based upon facts and circumstances known at such time and our ultimate liability was subject to change as further analysis is completed and state sales tax returns are filed. During the nine months ended December 31, 2014 we successfully completed and filed several state sales tax returns which concluded our obligation for historical sales taxes in those states. In addition we continued to work through the process in the remaining states. As a result of this work, we determined that our exposure had increased above and beyond our original accrual and as a result, we recorded an additional accrual of $460,000 during the three months ended December 31, 2014. We are hopeful that we are far enough in the process that we have accrued for the ultimate amount of liability that will be paid but our work was based upon facts and circumstances known at such time and our ultimately liability is subject to change as further analysis is completed and state sales tax returns are filed.
