The Company’s ownership in the fund is 19%. The clawback liability is joint and several, such that the Company may be required to fund the clawback for other general partners should they default. The Company believes its potential liability due to the possibility of default by other general partners is remote.

The maximum additional clawback liability is $0.3 million which was reflected in Other long-term liabilities on the Consolidated Balance Sheet at March 31, 2018. In October 2001, the Company entered into an agreement with a former Chairman and Chief Executive Officer of the Company, to provide for annual payments of $0.65 million per year and certain health care and other benefits for life. The related current liability of $0.8 million was included in Accrued expenses and other current liabilities and the long-term portion of $1.7 million was included in Other long-term liabilities on the Consolidated Balance Sheet at March 31, 2018.

The letter of credit was secured by cash and was classified as Long-term restricted cash equivalents on the Consolidated Balance Sheet as of December 31, 2017. During the first quarter of 2018, the restriction on the cash lapsed in connection with the termination of the related letter of credit and is classified as Cash and cash equivalents on the Consolidated Balance Sheet as of March 31, 2018. In January 2018, the Company announced a change in strategy and implemented an initiative to reduce the operating costs of the Company. In April 2018, the Company announced additional management changes intended to further streamline the Company's organizational structure and further reduce its operating costs. In connection with the changes that the Company has implemented, the Company will incur approximately $3.8 million of severance payments to terminated employees that will be paid over approximately twelve months. The Company has agreements with certain remaining employees that provide for severance payments to the employee in the event the employee is terminated without cause or an employee terminates his employment for “good reason.” The Company recognized $1.1 million of severance expense for the three months ended March 31, 2018 and $1.0 million was classified as accrued compensation and benefits on the Consolidated Balance Sheet as of March 31, 2018. The maximum aggregate exposure under employment and severance agreements for remaining employees was approximately $6.7 million at April 15, 2018. In June 2011, the Company's former partner company, Advanced BioHealing, Inc. (“ABH”) was acquired by Shire plc (“Shire”). Prior to the expiration of the escrow period in March 2012, Shire filed a claim against all amounts held in escrow related to the sale based principally upon a United States Department of Justice (“DOJ”) false claims act investigation relating to ABH (the “Investigation”). In connection with the Investigation, in July 2015 the Company received a Civil Investigation Demand-Documentary Material (“CID”) from the DOJ regarding ABH and Safeguard’s relationship with ABH. Pursuant to the CID, the Company provided the requested materials and information. To the Company’s knowledge, the CID was related to multiple qui tam (“whistleblower”) actions, one of which was filed in 2014 by an ex-employee of ABH that named the Company and one of the Company’s employees along with other entities and individuals as defendants. At this time, the DOJ has declined to pursue the qui tam action as it relates to the Company and such Company employee. In addition, in connection with the above matters, the Company and other former equity holders in ABH recently entered into a settlement and release with Shire, which resulted in the release to Shire of all amounts held in escrow related to the sale of ABH.
