Debt Covenants [Table Text Block]				The Financing Agreement requires the Company to comply with a financial statement covenant that stipulates a maximum leverage ratio (defined to mean the ratio of (a) consolidated total funded indebtedness to (b) consolidated EBITDA) of no greater than 4.35:1.00 for the four quarters ending June 30, 2016; 5.40:1.00 for the four quarters ending September 30, 2016; 4.20:1.00 for the four quarters ending December 31, 2016 and thereafter declining over time from 3.50:1.00 to 2.50:1.00. The Financing Agreement also restricts the Company from making capital expenditures in excess of $20 million in any fiscal year. As of September 30, 2016 the Company was in compliance with these covenants. The Company’s ability to satisfy the leverage ratio covenant in the future is heavily dependent on its ability to increase bookings and billings above levels experienced over the last 12 months. In recent quarters, the Company has experienced volatility in bookings and billings resulting from, among other things, (i) its transition towards subscription and recurring revenue streams and the resulting decline in traditional upfront product sales, (ii) volatility in currency rates and in particular the strengthening of the US dollar against the Euro, (iii) dramatic changes in the media industry and the impact it has on the Company’s customers and (iv) the impact of new and anticipated product launches and features. In addition to the impact of new bookings and billings, GAAP revenues recognized as the result of the existence of Implied Maintenance Release PCS (as defined below) in prior periods will decline significantly for the remainder of 2016 and in 2017, which will have an adverse impact on the Company’s leverage ratio. In the event bookings and billings in future quarters are lower than the Company currently anticipates, it may be forced to take remedial actions which could include, among other things (and where allowed by the Lenders), (i) further cost reductions, (ii) seeking replacement financing, (iii) raising additional equity or (iv) disposing of certain assets or businesses. Such remedial actions, which may not be available on favorable terms or at all, could have a material adverse impact on the Company’s business. If the Company is not in compliance with the leverage ratio and is unable to obtain an amendment or waiver, such noncompliance may result in an event of default under the Financing Agreement, which could permit acceleration of the outstanding indebtedness under the Financing Agreement and require the Company to repay such indebtedness before the scheduled due date. If an event of default were to occur, the Company might not have sufficient funds available to make the payments required. If the Company is unable to repay amounts owed, the lenders may be entitled to foreclose on and sell substantially all of the Company’s assets, which secure its borrowings under the Financing Agreement.
