Quarterly performance is affected by, among other things, weather conditions, timing of onsite projects, the value of our products, foreign exchange rates, market demand and the timing of our growth capital investments as well as acquisitions and the contributions from those investments. Growth capital investments completed in the first half of the year will tend to strengthen the second half financial performance. Revenue from certain business units is impacted by seasonality. However, due to the diversity of our business, the impact is limited on a consolidated basis. For example, waste volumes received at our oilfield facilities decline in the second quarter due to road bans which restrict drilling activity. This decline is offset by increased activity in our Eastern Onsite business unit due to the aqueous nature of work performed, as well as potentially by fluctuations in the value of our products or event-based waste receipts at SCL. As experienced over the last eight quarters, fluctuations in the value of our products can impact results.
