The service-based Restricted Stock Award program (RSA), designed for recruitment, retention and special recognition purposes, also provides for awards of restricted stock to key employees.
The following summarizes the activity of the Executive Continuity Award program and RSA program for the three years ending December 31, 2014:
## Table 0 ##
At December 31, 2014, 2013 and 2012 a total of 16.3 million, 17.8 million and 19.3 million shares, respectively, were available for grant under the ICP.
Stock-based compensation expense and related income tax benefits were as follows:
## Table 1 ##
At December 31, 2014, $117 million of compensation cost, net of estimated forfeitures, related to unvested restricted performance shares, executive continuity awards and restricted stock attributable to future performance had not yet been recognized.
This amount will be recognized in expense over a weighted-average period of 1.6 years.
NOTE 19 FINANCIAL INFORMATION BY INDUSTRY SEGMENT AND GEOGRAPHIC AREA International Paper’s industry segments, Industrial Packaging, Printing Papers and Consumer Packaging Businesses, are consistent with the internal structure used to manage these businesses.
All segments are differentiated on a common product, common customer basis consistent with the business segmentation generally used in the Forest Products industry.
Following the July 1, 2014 spinoff of xpedx, which historically represented the Company's Distribution reportable segment, the assets of the xpedx business totaling $1.2 billion as of December 31, 2013 were adjusted off the consolidated balance sheet and are not included on the consolidated balance sheet as of December 31, 2014.
For management purposes, International Paper reports the operating performance of each business based on earnings before interest and income taxes (EBIT).
Intersegment sales and transfers are recorded at current market prices.
External sales by major product is determined by aggregating sales from each segment based on similar products or services.
External sales are defined as those that are made to parties outside International Paper’s consolidated group, whereas sales by segment in the Net Sales table are determined using a management approach and include intersegment sales.
The Company also holds a 50% interest in Ilim that is a separate reportable industry segment.
The Company recorded equity earnings (losses), net of taxes, of $(194) million, $(46) million and $56 million in 2014, 2013, and 2012, respectively, for Ilim.
Equity earnings (losses) includes an after-tax foreign exchange gain (loss) of $(269) million, $(32) million and $16 million in 2014, 2013 and 2012, respectively, primarily on the remeasurement of U. S.  dollar-denominated net debt.
Part II, Item 7 In 2006, cash provided by financing activities was $291 million which was primarily due to the proceeds from employee stock plans ($442 million) and an increase in debt of $1.5 billion partially offset by the repurchase of 17.99 million shares of Schlumberger stock ($1.07 billion) and the payment of dividends to shareholders ($568 million).
Schlumberger believes that at December 31, 2006, cash and short-term investments of $3.0 billion and available and unused credit facilities of $2.2 billion are sufficient to meet future business requirements for at least the next twelve months.
Summary of Major Contractual Commitments
## Table 2 ##
1.
Excludes future payments for interest.
Includes amounts relating to the $1,425 million of Convertible Debentures which are described in Note 11 of the Consolidated Financial Statements.2.
Represents an estimate of contractual obligations in the ordinary course of business.
Although these contractual obligations are considered enforceable and legally binding, the terms generally allow Schlumberger the option to reschedule and adjust their requirements based on business needs prior to the delivery of goods.
Refer to Note 4 of the Consolidated Financial Statements for details regarding potential commitments associated with Schlumberger’s prior business acquisitions.
Refer to Note 20 of the Consolidated Financial Statements for details regarding Schlumberger’s pension and other postretirement benefit obligations.
Schlumberger has outstanding letters of credit/guarantees which relate to business performance bonds, custom/excise tax commitments, facility lease/rental obligations, etc.
These were entered into in the ordinary course of business and are customary practices in the various countries where Schlumberger operates.
Critical Accounting Policies and Estimates The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires Schlumberger to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses.
The following accounting policies involve “critical accounting estimates” because they are particularly dependent on estimates and assumptions made by Schlumberger about matters that are inherently uncertain.
A summary of all of Schlumberger’s significant accounting policies is included in Note 2 to the Consolidated Financial Statements.
Schlumberger bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.
Actual results may differ from these estimates under different assumptions or conditions.
Multiclient Seismic Data The WesternGeco segment capitalizes the costs associated with obtaining multiclient seismic data.
The carrying value of the multiclient seismic data library at December 31, 2006, 2005 and 2004 was $227 million, $222 million and $347 million, respectively.
Such costs are charged to Cost of goods sold and services based on the percentage of the total costs to the estimated total revenue that Schlumberger expects to receive from the sales of such data.
However, except as described below under “WesternGeco Purchase Accounting,” under no circumstance will an individual survey carry a net book value greater than a 4-year straight-lined amortized value.
areas.
However, these increases were offset by lower WesternGeco marine vessel utilization and reduced multiclient seismic sales.
Year-on-year, pretax operating margin increased 14 bps, to 29.5%, largely due to the higher-margin exploration activities that benefited Wireline Technologies and Testing Services.
Higher margin software sales also contributed to the improvement.
These increases were partially offset by lower profitability in WesternGeco due to lower vessel utilization and lower PetroTechnical Services multiclient seismic sales.
Drilling Group Full-year 2014 revenue of $18.5 billion was 8% higher than the 2013, primarily due to the robust demand for Drilling & Measurements services and M-I SWACO Technologies as activity strengthened in the North America and Middle East & Asia Areas.
Rig revenue from the May 2014 acquisition of Saxon also contributed to the growth.
Year-on-year, pretax operating margin increased 171 bps, to 21.0%, primarily due to the increase in higher-margin exploration activities of Drilling & Measurements in North America offshore and in the international markets.
Improved profitability on Integrated Project Management activities also contributed to the margin increase.
Production Group Full-year 2014 revenue of $18.1 billion increased 14% compared to 2013, primarily from Well Services pressure pumping technologies driven by market share gains, improvements in operational efficiency and the introduction of new technologies.
Schlumberger Production Management (SPM) revenue grew as projects in Latin America continued to progress ahead of work plans.
Revenue from the expanding artificial lift business also contributed to the year-onyear growth.
Year-on-year, pretax operating margin increased 138 bps, to 17.8%, mainly on improved profitability for Well Services and Well Intervention, particularly in the International Areas.
SPM activities also contributed to the margin expansion.
However, these improvements were partially offset by the decrease in margins in North America due to pressure pumping commodity cost inflation.
