Merger related costs of $75.6 million include severance and other external costs directly related to the Merger.
Transaction costs of $10.9 million for the year ending December 31, 2008 were comprised of $6.0 million for accelerated vesting of stock-based compensation, $4.0 million for bridge loan fees and $0.9 million of other costs and are included in selling, general and administrative expense in the Consolidated Statements of Income.
Preliminary Purchase Price Allocation Under the purchase method of accounting, the total preliminary purchase price was allocated to Grant Prideco’s net tangible and identifiable intangible assets based on their estimated fair values as of April 21, 2008.
The excess of the purchase price over the net tangible and identifiable intangible assets was recorded as goodwill.
The preliminary allocation of the purchase price was based upon preliminary valuations, and our estimates and assumptions are subject to change upon the receipt and management’s review of the final valuations.
The primary areas of the purchase price allocation, which are not yet finalized, relate to identifiable intangible assets, goodwill, certain preacquisition contingencies and related adjustments to deferred taxes.
The final valuation of net assets is expected to be completed as soon as possible, but no later than one year from the acquisition date.
The following table, set forth below, displays the total preliminary purchase price allocated to Grant Prideco’s net tangible and identifiable intangible assets based on their estimated fair values as of April 21, 2008 (in millions):

?Business?
of this Annual Report.
Influence of Oil and Gas Activity Levels on the Company?s Business The oil and gas industry in which the Company participates has historically experienced significant volatility.
Demand for the Company?s services and products depends primarily upon the general level of activity in the oil and gas industry worldwide, including the number of drilling rigs in operation, the number of oil and gas wells being drilled, the depth and drilling conditions of these wells, the volume of production, the number of well completions and the level of well remediation activity.
Oil and gas activity is in turn heavily influenced by, among other factors, oil and gas prices worldwide.
High levels of drilling and well remediation activity generally spurs demand for the Company?s products and services used to drill and remediate oil and gas wells.
Additionally, high levels of oil and gas activity increase cash flows available for oil and gas companies, drilling contractors, oilfield service companies, and manufacturers of oil country tubular goods (?OCTG?)
to invest in capital equipment that the Company sells.
Beginning in early 2004, increasing oil and gas prices led to steadily rising levels of drilling activity throughout the world.
Concerns about the long-term availability of oil and gas supply also began to build.
Consequently, the worldwide rig count increased 11% in 2006, 2% in 2007, and 7% in 2008.
As a result of higher cash flows realized by many of the Company?s customers, as well as the long-term concerns about supply-demand imbalance and the need to replace aging equipment, market conditions for capital equipment purchases improved significantly between 2006 and 2007, resulting in higher backlogs for the Company at the end of 2008 compared to the end of 2006 and 2007.
However, as a result of the financial crisis and significantly lower commodity prices, the worldwide drilling rig count declined 31% in 2009 and customers were far less willing to commit to major capital equipment purchases in 2009.
As a result, our order rates were substantially lower in 2009.
In 2010, as the financial crisis eased and oil prices recovered, order rates began to improve across a broad array of rig equipment, with a particular focus on continued build out of the deepwater fleet.2011 saw a further improvement in order rates as commodity prices remained at levels supporting sustained capital spending by our customers.
The rig count rose 16% in 2011 compared to 2010.
Backlog for the Company was approximately $10.2 billion at December 31, 2011 compared to approximately $5.0 billion and $6.4 billion for December 31, 2010 and 2009, respectively.
In 2009, 2010 and 2011, most of the Company?s revenue from Rig Technology resulted from major capital expenditures of drilling contractors, well servicing companies, and oil companies on rig construction and refurbishment, and well servicing equipment.
These capital expenditures are influenced by the amount of cash flow that contractors and service companies generate from drilling, completion, and remediation activity; as well as by the availability of financing, the outlook for future drilling and well servicing activity, and other factors.
Generally, the Company believes the demand for capital equipment lags increases in the level of drilling activity.
Most of the remainder of the Rig Technology segment?s revenue is related to the sale of spare parts and consumables, the provision of equipment-repair services, and the rental of equipment, which the Company believes are generally determined directly by the level of drilling and well servicing activity.
