Litigation

The Company is subject to legal proceedings and claims which arise in the ordinary course of its business. Although occasional adverse decisions or settlements may occur, the Company believes that the final disposition of such matters should not have a material adverse effect on its financial position, results of operations or liquidity.

Sales Tax

During 2012, the Company engaged a sales tax consultant to assist in determining the extent of its potential sales tax exposure. Based upon this analysis, management determined the Company had probable exposure for certain unpaid obligations, including interest and penalty, of approximately $1,100,000 including and prior to the year ended December 31, 2011. The Company has approximately $150,000 and $230,000 accrued as of June 30, 2016 and December 31, 2015, respectively. 

The Company continues to manage the liability by establishing voluntary disclosure agreements (VDAs) with the applicable states, which establishes a maximum look-back period and payment arrangements. However, if the aforementioned methods prove unsuccessful and the Company is examined or challenged by taxing authorities, there exists possible exposure of an additional $20,000, not including any applicable interest and penalties.

Prior to 2016, the Company successfully executed and paid in full VDAs in thirty one states totaling approximately $695,000 and is current with the subsequent filing requirements.

During the six months ended June 30, 2016, the Company executed five VDA’s totaling approximately $70,000.

The following table sets forth the change in the sales tax accrual as of June 30, 2016 and December 31, 2015:
