In the contract drilling segment, significant costs are incurred and passed through to customers with little or no markup. For the quarter and year ended December 31, 2012 these costs aggregated $10.4 million and $35 million respectively. In the same respective periods in 2011 these costs amounted to $11.3 million and $41.6 million. Savanna's accounting policy with respect to cost recoveries billed to customers is to include them as both revenue and operating expenses rather than net them. Although Savanna believes this most appropriately reflects the substance of the underlying transactions, the accounting treatment of cost recoveries varies in the oilfield services industry. There is no effect on overall operating margins whether cost recoveries are netted or not; however, the different treatments do result in different operating margin percentages as the same dollar margin is factored against lower revenue when cost recoveries are netted. As a result, Savanna believes it is useful to provide revenue excluding cost recoveries and the resulting operating margin percentages for comparative purposes.
