(1) Includes reclassification of freight billed to customers from sales and marketing expense to revenue of $0.4 million and $0.3 million for the first and second quarters of 2015, respectively, and $0.5 million, $0.4 million, $0.3 million, and $0.4 million for the first, second, third, and fourth quarters of 2014, respectively.

(2) Included in 2015 and 2014 quarterly gross profit is amortization of intangible assets of $1.6 million, $1.6 million, $1.6 million and $1.5 million for the first quarter, second quarter, third quarter and fourth quarter, respectively.

(3) Basic and diluted EPS amounts in each quarter are computed using the weighted-average number of shares outstanding during that quarter, while basic and diluted EPS for the full year is computed using the weighted-average number of shares outstanding during the year. Therefore, the sum of the four quarters’ basic or diluted EPS may not equal the full year basic or diluted EPS.
