Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	6. Income Taxes The Company had an effective tax rate of nil for the six months ended June 30, 2013 and 2012. The Company incurred losses before taxes for the six months ended June 30, 2013 and 2012. However, it has not recorded a tax benefit for the resulting net operating loss carryforwards, as the Company has determined that a full valuation allowance against its net deferred tax assets was appropriate based primarily on its historical operating results. In July 2008, the Company completed the sale of all of the outstanding capital stock of Xmark to Stanley. In January 2010, Stanley received a notice from the Canadian Revenue Agency (“CRA”) that the CRA would be performing a review of Xmark’s Canadian tax returns for the periods 2005 through 2008. This review covers all periods that the Company owned Xmark. In February 2011, and as revised on November 9, 2011, Stanley received a notice from the CRA that the CRA completed its review of the Xmark returns and was questioning certain deductions attributable to allocations from related companies on the tax returns under review. In November and December 2011, the CRA and the Ministry of Revenue of the Province of Ontario issued notices of reassessment confirming the proposed adjustments. The total amount of the income tax reassessments for the 2006-2008 tax years, including both provincial and federal reassessments, plus interest, was approximately $1.4 million. On January 20, 2012, the Company received an indemnification claim notice from Stanley related to the matter. The Company does not agree with the position taken by the CRA, and filed a formal appeal related to the matter on March 8, 2012. In addition, on March 28, 2012, Stanley received assessments for withholding taxes on deemed dividend payments in respect of the disallowed management fee totaling approximately $0.2 million, for which we filed a formal appeal on June 7, 2012. In October 2012, the Company submitted a Competent Authority filing to the U.S. IRS seeking relief in the matter. In connection with the filing of the appeals, Stanley was required to remit an upfront payment of a portion of the tax reassessment totaling approximately $950,000. The Company has also filed a formal appeal related to the withholding tax assessments, pursuant to which Stanley was required to remit an additional upfront payment of approximately $220,000. Pursuant to a letter agreement dated March 7, 2012, the Company has agreed to repay Stanley for the upfront payments, plus interest at the rate of five percent per annum, in 24 equal monthly payments beginning on June 1, 2012. To the extent that the Company and Stanley reach a successful resolution of the matter through the appeals process, the upfront payment (or a portion thereof) will be returned to Stanley or the Company as applicable. Based on the Company’s review of the correspondence and evaluation of the supporting detail, it does not believe that the ultimate resolution of this matter will have a material negative impact on the Company’s historical tax liabilities or results of operations. The Company has established an accrual of $400,000 for this contingency, which management believes is adequate. This accrual was reclassified as a liability to Stanley and recorded in the tax contingency line in the consolidated balance sheets, and a prepaid tax advance to Stanley in the amount of $708,000 has been recorded, as of June 30, 2013. During 2012 and continuing into 2013, the Company has been delinquent in its payments to Stanley. The Company and Stanley have agreed to monthly payments of approximately $26,000 per month for 2013. The outstanding balance of the liability to Stanley is $896,000 as of June 30, 2013.
