Earnings per share amounts for each quarter are required to be computed independently using the weighted average number of shares outstanding during the period. As a result, the sum of the individual quarterly earnings per share amounts may not agree to the earnings per share calculated for the year.

Gross profit in the fourth quarter of 2014 benefited from higher levels of claim settlements and change orders.
