Revenue Recognition

2. Revenue Recognition

The timing of revenues is dependent on the Company's backlog, contract awards, and the performance requirements of each contract. The Company's revenues are also affected by the timing of its clients planned remediation work as well as the timing of unplanned emergency spills. Historically, planned remediation work generally increases during the third and fourth quarters. Although the Company believes that the historical trend in quarterly revenues for the third and fourth quarters of each year are generally higher than the first and second quarters, there can be no assurance that this will occur in future periods.
