disclosed our conclusion that no impairment was needed, in future filings we will provide further detail regarding our estimates and assumptions impacting future assessments when meaningful to an
understanding of our conclusion. Following is an example of the revised disclosure as it would have appeared in the Form 10-K for the fiscal year ended December&nbsp;31, 2014 (the underlined text is the proposed revision to the disclosure): </P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:8%; text-indent:4%; font-size:10pt; font-family:Times New Roman">In light of the significant decline in oil and natural gas commodity prices beginning in the fourth quarter of 2014 and
continuing into 2015, we deemed it necessary to <U>perform a Step 1 analysis as required by ASC 360-10-35 to</U> assess the recoverability of long-lived assets within our contract drilling and pressure pumping segments. With respect to these assets,
we estimated future cash flows over the expected <U>remaining</U> life of the assets, and determined that, on an undiscounted basis, expected cash flows exceeded the carrying value of the long-lived assets. <U>The expected cash flows for our
contract drilling segment include our backlog of commitments for contract drilling revenues under term contracts, which was approximately $1.5 billion at December&nbsp;31, 2014. We expect approximately $953 million of our backlog to be realized in
2015. Rigs not under term contracts will be subject to pricing in the spot market. Utilization and rates for rigs in the spot market and for our pressure pumping segment were estimated based upon our historical experience in prior downturns. Also,
the expected cash flows for our contract drilling and pressure pumping segments are based on the assumption that oil prices and activity levels in both segments would begin to recover in late 2015 and continue to recover in 2016. This oil price
assumption is consistent with forecast information published by the United States Energy Information Administration in January 2015. While we believe our assumptions with respect to future pricing for oil and natural gas were reasonable, actual
future prices may vary significantly from the ones we assumed. </U>Based on this assessment, no impairment was indicated. Impairment considerations related to our oil and natural gas segment are discussed below. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman"><B>2. Please tell us about rig utilization rates as of December&nbsp;31, 2014 and June&nbsp;30, 2015 using classifications similar to the
information presented on page 5 of your Form 10-K. In addition, please describe management&#146;s plans for rigs not currently under contract including your prospects for entering into drilling contracts. </B></P>

rigs in North America has declined significantly in 2015 as a result of the collapse in oil prices which began in the fourth quarter of 2014. A rig is &#147;stacked&#148; when it is released by a customer and we have not entered into a new contract
for that rig to work. Generally, stacked rigs are stored in secure locations and major components are serviced in an effort to maintain the stacked rigs in a condition whereby they can be reactivated without incurring excessive cost if demand
improves. We currently believe that until oil or natural gas prices improve, we will not experience any meaningful increase in demand for North American land drilling rigs. </P>

qualitative factors to determine whether the existence of events or circumstances would lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the
totality of events or circumstances, a company determines it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is considered to be unnecessary. Given
this guidance, we elected to use the qualitative approach to determine if the quantitative approach was necessary. Our qualitative assessment of goodwill was a comprehensive analysis of factors set forth in ASC 350-20-35-3C. Each factor was first
evaluated to determine if its impact on each reporting unit&#146;s fair value was positive, negative or neutral. We then assessed the magnitude of the potential impact of each factor as being high, medium or low. We also considered whether the
evidence supporting these assessments was objective or subjective. The key factors we considered included the following: </P> <P STYLE="font-size:6pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>
