”Our revenue growth reflects the investment that we have made in pursuing specific wireless markets such as offloading, SCADA, Positive Train Control, Network Timing with High Rejection GPS antennas, and Fleet Management,” said Marty Singer, PCTEL’s Chairman and CEO. “It also reflects our technology investment in advanced scanning receiver capabilities required by new cellular technologies, such as LTE and TD-LTE,” added Singer.

This schedule reconciles the company’s GAAP operating income and GAAP net income to its non-GAAP operating income and non-GAAP net income. The company believes that presentation of this schedule provides meaningful supplemental information to both management and investors that is indicative of the company’s core operating results and facilitates comparison of operating results across reporting periods. The company uses these non-GAAP measures when evaluating its financial results as well as for internal planning and forecasting purposes. These non-GAAP measures should not be viewed as a substitute for the company’s GAAP results.

(a) These adjustments reflect stock based compensation expense, amortization of intangible assets, restructuring charges, impairment charges, and the loss on the sale of product lines.

(b) These adjustments include the items described in footnote (a) as well as the non-cash income tax expense, noncontrolling interest, and investment income related to noncontrolling interest.
