SIGNIFICANT CLIENTS AND OTHER CONCENTRATIONS

(4)       SIGNIFICANT CLIENTS and other concentrations

The Company had one client that contributed in excess of 10% of total revenue for the three months ended March 31, 2014. This client operates in the communications industry and is included in the Customer Management Services segment. This client contributed 11.6% and 11.9% of total revenue for the three months ended March 31, 2014 and 2013. This client had an outstanding receivable balance of $30.4 million and $25.0 million as of March 31, 2014 and 2013.

The loss of one or more of its significant clients could have a material adverse effect on the Company's business, operating results, or financial condition. The Company does not require collateral from its clients. To limit the Company's credit risk, management performs periodic credit evaluations of its clients and maintains allowances for uncollectible accounts and may require pre-payment for services. Although the Company is impacted by economic conditions in various industry segments, management does not believe significant credit risk existed as of March 31, 2014.
