(1)
Included in 2016 quarterly gross profit is amortization of intangible assets of $1.6 million, $1.6 million, $1.6 million and $1.7 million for the first quarter, second quarter, third quarter and fourth quarter, respectively. Included in 2015 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.

(2)
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.
