Subsequent Events [Abstract]
Subsequent Events	15. Subsequent Events In connection with a recent review by the Company of equity compensation awards made under its 2000 Stock Incentive Plan, which is described in greater detail in Footnote 10 herein, the Company determined that it had inadvertently exceeded the annual per-person sub-limits set forth in the 2000 Stock Incentive Plan. The awards that exceeded the per-person sub-limits included certain RS, RSU and stock option awards made to certain of its current and past officers and directors. The amount of common stock represented by these awards in excess of the per-person annual sub-limits totaled approximately 1.6 million shares. The awards that exceeded the per-person sub-limits included several awards that were issued immediately following the Company's business combination with Transave, several awards that were negotiated with new hires pursuant to employment agreements or offers of employment, and certain other awards made subsequent to our 2011 one-for-ten reverse stock split. The Company has not exceeded the aggregate maximum share limit approved by shareholders under the 2000 Stock Incentive Plan (currently 3,925,000 shares of common stock), whether as a result of previously-issued awards or currently outstanding awards. As a result of the foregoing review and findings with respect to awards in excess of the per-person annual sub-limits, on March 7, 2013, the Company's Board approved a remediation and compliance plan recommended by the Board's compensation committee. Pursuant to the remediation and compliance plan, on March 14, 2013, the Company provided notice to each current employee and director who was a recipient of an affected equity compensation award. As of March 15, 2013, each current employee and director who holds an affected equity compensation award that is currently unvested and/or unexercised, has entered into a waiver and consent with the Company. Pursuant to such waiver and consent, each affected current employee or director agreed that the unvested portion of such awards in excess of the sub-limits shall not vest and shall not become exercisable and any vested portion of such awards of stock options in excess of the sub-limits shall not be exercisable, in each case, unless the Company's shareholders ratify and approve the portion of the affected awards that were in excess of the applicable sub-limits. If the Company's shareholders do not ratify and approve the affected portion of such awards, such portions would be deemed forfeited. In furtherance of the foregoing, on March 7, 2013, as part of the remediation and compliance plan, the Board approved the recommendation of a special committee of the Board that we seek shareholder approval at the Company's 2013 annual meeting of shareholders to ratify and approve the excess portions of the affected awards. On March 12, 2013, the Company notified Nasdaq of the grants previously made in excess of the annual per-person sublimits provided for by 2000 Stock Incentive Plan. The Company believes that a decision by the Company to increase the annual sub-limits would have constituted an immaterial amendment to the 2000 Stock Incentive Plan, which amendment would not have required shareholder approval under applicable Nasdaq guidance. However, because the grant of certain awards exceeded the sublimits applicable at the time the grants were made, it is possible that Nasdaq will conclude that the Company issued securities pursuant to the 2000 Stock Incentive Plan without shareholder approval in violation of Nasdaq Listing Rule 5635(c). In a March 13, 2013 letter to Nasdaq, the Company submitted a remediation and compliance plan, which the Company refers to as the remediation plan, to address the grants made in excess of the 2000 Stock Incentive Plan sub-limits. Among other items, the Company's remediation plan conditions the continued vesting and exercise of the portion of each equity compensation award issued to our current employees and directors in excess of the 2000 Stock Incentive Plan's sub-limits on approval by the Company's shareholders of such portion of the affected grants. If our shareholders do not ratify and approve the affected portions of such awards, such portions would be deemed forfeited. As part of the Company's remediation plan, and after receiving confirmation from Nasdaq's staff on Nasdaq's continued reliance on Staff Interpretation Letter 2007-28, on March 15, 2013, the compensation committee of the Board recommended and the Board approved an amendment to the 2000 Stock Incentive Plan to replace the three individual annual per person equity compensation limits with a single annual aggregate stock option, performance share and restricted stock sub-limit of 1,500,000 shares. The Company did not change the overall share reserve for the 2000 Stock Incentive Plan of 3,925,000 shares, which was approved by the Company's shareholders in May 2011.
