Related-Party Transactions [Abstract]
Related-Party Transactions	15. Related-Party Transactions The Company uses the law firm of Blank Rome LLP for legal services. A partner of that firm is the son-in-law of the Chairman of the Company’s Board of Directors. For the three months ended March 31, 2018, the Company paid that firm approximately $103 for legal services and costs. For the three months ended March 31, 2017, the Company paid that firm approximately $72 for legal services and costs. The Chairman of our Board of Directors is considered independent under applicable Nasdaq and Securities and Exchange Commission rules because (i) no payments were made to the Chairman or the partner directly in exchange for the services provided by the law firm and (ii) the amounts paid to the law firm did not exceed the thresholds contained in the Nasdaq standards. Furthermore, the aforementioned partner does not provide any legal services to the Company and is not involved in billing matters.
