The Company accounts for share-based compensation by measuring the cost of the employee services received in exchange for an award of equity instruments, including grants of stock options, based on the fair value of the award at the date of grant. In addition, to the extent that the Company receives an excess tax benefit upon exercise of an award, such benefit is reflected as cash flow from financing activities in the consolidated statement of cash flows.
 
Stock-based compensation expense for the three months ended June 30, 2017 and 2016 was $10,688 and $22,272, respectively, and stock based compensation expense for the six months ended June 30, 2017 and 2016 was $10,688 and $38,322, respectively, relating to employee and director RSUs, and included in selling, general and administrative expenses in the accompanying consolidated statements of operations.
