As of December 31, 2012, Schlumberger had approximately $6.3 billion of cash and short-term investments on hand.
Schlumberger had separate committed debt facility agreements aggregating $4.1 billion with commercial banks, of which $3.8 billion was available and unused as of December 31, 2012.
This included $3.5 billion of committed facilities which support commercial paper borrowings in the United States and Europe.
Schlumberger believes that these amounts are sufficient to meet future business requirements for at least the next 12 months.
Schlumberger did not have any commercial paper borrowings outstanding as of December 31, 2012.
## Table 0 ##
(1) Excludes future payments for interest.
(2) Excludes interest on $1.6 billion of variable rate debt, which had a weighted average interest rate of 3.6% as of December 31, 2012.
(3) 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 its requirements based on business needs prior to the delivery of goods.
Refer to Note 18 Pension and Other Benefit Plans of the Consolidated Financial Statements for details regarding Schlumberger’s pension and other postretirement benefit obligations.
As discussed in Note 14 Income Taxes of the Consolidated Financial Statements, included in the Schlumberger Consolidated Balance Sheet at December 31, 2012 is approximately $1.45 billion of liabilities associated with uncertain tax positions in the over 100 jurisdictions in which Schlumberger conducts business.
Due to the uncertain and complex application of tax regulations, combined with the difficulty in predicting when tax audits throughout the world may be concluded, Schlumberger cannot make reliable estimates of the timing of cash outflows relating to these liabilities.
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 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 business capitalizes the costs associated with obtaining multiclient seismic data.
The carrying value of the multiclient seismic data library at December 31, 2012 and 2011 was $518 million and $425 million, respectively.
Such costs are charged to Cost of revenue 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, under no circumstances will an individual survey carry a net book value greater than a 4-year, straight-line amortized value.
The carrying value of surveys is reviewed for impairment annually as well as when an event or change in circumstance indicates an impairment may have occurred.
Adjustments to the carrying value are recorded when it is

In 2009, Schlumberger learned that United States officials began a grand jury investigation and an associated regulatory inquiry, both related to certain Schlumberger operations in specified countries that are subject to United States trade and economic sanctions.
Also in 2009, prior to being acquired by Schlumberger, Smith received an administrative subpoena with respect to its historical business practices in certain countries that are subject to United States trade and economic sanctions.
Schlumberger is cooperating with the governmental authorities.
On April 20, 2010, a fire and explosion occurred onboard the semisubmersible drilling rig Deepwater Horizon, owned by Transocean Ltd.  and under contract to a subsidiary of BP plc.
Pursuant to a contract between M-I SWACO and BP, M-I SWACO provided certain services under the direction of BP.
A number of legal actions, certain of which name an M-I SWACO entity as a defendant, have been filed in connection with the Deepwater Horizon incident, and additional legal actions may be filed in the future.
Based on information currently known, the amount of any potential loss attributable to M-I SWACO with respect to potential liabilities related to the incident would not be material to Schlumberger’s consolidated financial statements.
Schlumberger and its subsidiaries are party to various other legal proceedings from time to time.
A liability is accrued when a loss is both probable and can be reasonably estimated.
Management believes that the probability of a material loss is remote.
However, litigation is inherently uncertain and it is not possible to predict the ultimate disposition of these proceedings.17.

USRIP, or the Plan, Investment and Asset Allocation Strategies.
The primary goal of the asset allocation strategy of the Plan is to produce a total investment return which will satisfy future annual cash benefit payments to participants and minimize future contributions from the Company.
Additionally, this strategy will diversify the plan assets to minimize nonsystemic risk and provide reasonable assurance that no single security or class of security will have a disproportionate impact on the Plan.
Investment managers are required to abide by the provisions of ERISA.
Standards of performance for each manager include an expected return versus an assigned benchmark, a measure of volatility, and a time period of evaluation.
The asset allocation strategy is determined by our external advisor forecasting investment returns by asset class and providing allocation guidelines to maximize returns while minimizing the volatility and correlation of those returns.
Investment recommendations are made by our external advisor, working in conjunction with our in-house Investment Committee.
The asset allocation and ranges are approved by our in-house Investment Committee and Plan Administrators, who are Named Fiduciaries under ERISA.
The Plan, in an effort to meet asset allocation objectives, utilizes a variety of asset classes which have historically produced returns which are relatively uncorrelated to those of the S&P 500 in most environments.
Asset classes included in this category of alternative assets include hedge funds, private equity (including secondary private equity) and real assets (real estate, funds of hard asset securities and private equity funds focused on real assets).
The primary benefits of using these types of asset classes are: (1) their non-correlated returns reduce the overall volatility of the Plan’s portfolio of assets, and (2) their ability to produce superior risk-adjusted returns.
Additionally, the Plan allows certain of their managers, subject to specific risk constraints, to utilize derivative instruments in order to enhance asset return, reduce volatility or both.
Derivatives are primarily employed by the Plans in their fixed income portfolios and in the hedge fund-of-funds area.
Derivatives can be used for hedging purposes to reduce risk.
No shares of Equifax common stock were directly owned by the Plan at December 31, 2017 or 2016.
Not more than 5% of the portfolio (at cost) shall be invested in the securities of any one issuer, with the exceptions of U. S.  Treasury and government agency securities.
The following asset allocation ranges and actual allocations were in effect as of December 31, 2017 and 2016:

CRIP Investment and Asset Allocation Strategies.
The primary goal of the asset allocation strategy of the Plan is to produce a total investment return which will satisfy future annual cash benefit payments to participants and minimize future contributions from the Company.
Additionally, this strategy will diversify the plan assets to minimize nonsystemic risk and provide reasonable assurance that no single security or class of security will have a disproportionate impact on the Plan.
Due to the high funded status of the Plan, the Investment Committee of the CRIP has adopted a conservative asset allocation of 50/50 in equities and fixed income.
The Investment Committee maintains an investment policy for the CRIP, which imposes certain limitations and restrictions regarding allowable types of investments.
The current investment policy imposes those restrictions on investments or transactions such as (1) Equifax common stock or securities, except as might be incidental to any pooled funds which the plan may have, (2) commodities or loans, (3) short sales and the use of margin accounts, (4) put and call options, (5) private placements, and (6) transactions which are “related-party” in nature as specified by the Canadian Pension Benefits Standards Act and its regulations.
with these proceedings and investigations, it is not possible to estimate the amount of loss or range of possible loss that might result from adverse judgments, settlements, penalties or other resolution of such proceedings and investigations based on the early stage of these proceedings and investigations, that alleged damages have not been specified, the uncertainty as to the certification of a class or classes and the size of any certified class, as applicable, and the lack of resolution on significant factual and legal issues.
The Tax Cuts and Jobs Act of 2017 (“Tax Act”), as signed by the President of the United States on December 22, 2017, significantly revises U. S.  tax law.
The legislation will positively impact the Company’s ongoing effective tax rate due to the reduction of the U. S.  federal corporate tax rate from 35% to 21%.
The Tax Act makes major changes to the U. S.  international tax system.
Under previous law, foreign earnings were subject to U. S.  tax when repatriated to the U. S.  Under the Tax Act, foreign earnings are generally exempt from U. S.  tax.
Additionally, there is a one-time deemed repatriation tax on undistributed foreign earnings and profits (the “transition tax”).
The Tax Act imposes other U. S.  taxes on “global intangible low taxed income” and “base erosion anti-abuse transactions.
” Other significant changes include limitations on the deductibility of interest expense and executive compensation, and repeal of the deduction for domestic production activities.
As a result of the current interpretation and estimated impact of the Tax Act, the Company recorded adjustments totaling a net tax benefit of $48.3 million in the fourth quarter of 2017 to provisionally account or the estimated impact.
