However, this risk is limited due to the Company’s large number of clients and their dispersion across many different industries and geographies. At December 31, 2017 and 2016, the Company had </font><font style="font-family:inherit;font-size:10pt;">no</font><font style="font-family:inherit;font-size:10pt;"> significant concentrations of risk.</font></div></div>

For each assignment, the Company and its client enter into a contract that outlines the general terms and conditions of the assignment. Typically, the Company is paid a retainer for its executive search services equal to approximately one-third of the estimated first year compensation for the position to be filled. In addition, generally, if the actual compensation of a placed candidate exceeds the estimated compensation, the Company often is authorized to bill the client for one-third of the excess. Indirect expenses are calculated as a percentage of the retainer with certain dollar limits per search. The Company generally bills its clients for its retainer and indirect expenses in one-third increments over a </font><font style="font-family:inherit;font-size:10pt;">three</font><font style="font-family:inherit;font-size:10pt;">-month period commencing in the month of a client’s acceptance of the contract.</font></div><div style="line-height:120%;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Net revenue is recognized when earned and realizable and therefore when the following criteria have been met: (a) persuasive evidence of an arrangement exists, (b) services have been rendered, (c) the fee to our client is fixed or determinable, and (d) collectability is reasonably assured. Taxes collected from clients and remitted to governmental authorities are presented on a net basis. Typically, net revenue from standard executive search engagements is recognized over the expected average period of performance, in proportion to the estimated personnel time incurred to fulfill our obligations under the arrangements. Net revenue in excess of the retainer, resulting from actual compensation of the placed candidate exceeding the estimated compensation, is recognized upon completion of the executive search when the amount of the additional fee is known.</font></div><div style="line-height:120%;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Net revenue associated with culture shaping services is recognized proportionally as services are performed.
