Segment Reporting [Abstract]  
Segments and Major Customers
Segments and Major Customers
For the three and six months ended June 30, 2015, MID and CRD were reportable segments as each of them met the quantitative thresholds for disclosure as a reportable segment. The results of the remaining operating segments were shown under “Other.” Additionally, some employees moved departments in the fourth quarter of 2014 causing a change in the prior period reportable segment financial results. The presentation of the 2014 segment data has been updated accordingly to conform with the updated segment presentation.
The Company evaluates the performance of its segments based on segment operating income (loss), which is defined as revenue minus segment operating expenses. Segment operating expenses are comprised of direct operating expenses.
Segment operating expenses do not include sales, general and administrative expenses and the allocation of certain expenses managed at the corporate level, such as stock-based compensation, amortization, and certain bonus and acquisition costs. The “Reconciling Items” category includes these unallocated sales, general and administrative expenses as well as corporate level expenses.
The tables below present reported segment operating income (loss) for the three and six months ended June 30, 2015 and 2014, respectively.
