Contingencies [Abstract]
Contingencies	17. Contingencies The Company is subject to various legal proceedings that arise from time to time in the ordinary course of its business. Although the Company believes that the various proceedings brought against it are without merit, and that it has adequate product liability and other insurance to cover any claims, litigation is subject to many factors which are difficult to predict and there can be no assurance that the Company will not incur material costs in the resolution of legal matters.

Legal Proceedings The Glodek Litigation On July 25, 2016, Kevin Glodek filed and served a Summons with Notice against Kadmon Holdings, LLC and Kadmon Holdings, Inc. in the New York State Supreme Court, for the county of New York, for an amount of no less than $2.8 million with interest, plus costs and disbursements. Company counsel demanded a complaint and that complaint was served and filed on September 6, 2016. In the complaint, Glodek alleges fraud, misrepresentation, breach of contract, breach of the implied covenant of good faith and fair dealing, and unjust enrichment, for amounts to be determined at trial, but in no event less than $4 million with interest, plus costs and disbursements. Glodek’s claims arise out of a 2015 settlement agreement, in which he released all claims he had against Kadmon Holdings, LLC and Kadmon Holdings, Inc. On September 21, 2016, Glodek filed an Amended Summons and an Amended Complaint adding Steven N. Gordon and Mr. Poukalov as named defendants. All defendants moved (i) to dismiss the Amended Complaint and (ii) for sanctions or, in the alternative, to disqualify Glodek’s counsel. Argument on the motions was conducted on January 24, 2017 before the Honorable Anil Singh. On April 18, 2017, the complaint was dismissed in its entirety. Glodek filed a Notice of Appeal on May 18, 2017, and had 9 months within which to “perfect” his appeal by filing a brief and the record. Defendants filed a Notice of Cross Appeal on May 18, 2017. Glodek has filed a motion to expand his time to perfect his appeal, which the defendants have opposed.

Should the Company determine that any future obligations will exist, the Company will record expense equal to the amount which is deemed probable and estimable.
