Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Basis of Presentation and Nature of Operations	'
	A.  Basis of Presentation
	In the opinion of management, the accompanying financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of (a) the consolidated results of operations for the three and six month periods ended June 30, 2014 and 2013, (b) the consolidated comprehensive income for the three and six month periods ended June 30, 2014 and 2013, (c) the consolidated financial position at June 30, 2014 and December 31, 2013, (d) the consolidated changes in stockholders’ equity for the six month periods ended June 30, 2014 and 2013, and (e) the consolidated cash flow for the six month periods ended June 30, 2014 and 2013.  The financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (U.S. GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission.  Certain amounts for prior periods have been reclassified to conform to the current period financial statement presentation.
	We have revised previously reported amounts on the Consolidated Statement of Cash Flow for the six months ended June 30, 2013 to correct for customer advances invoiced but not yet paid and to correct for certain non-cash transactions impacting Receivables - trade and other and Accounts payable. Although these revisions did not impact Net cash provided by operating activities, cash provided by Receivables - trade and other decreased by $200 million, cash provided by Accounts payable increased by $83 million and cash used for Customer advances decreased by $117 million from the amounts previously reported for the six month period ended June 30, 2013. Management has concluded that the impact was not material to any period presented.
	Interim results are not necessarily indicative of results for a full year. The information included in this Form 10-Q should be read in conjunction with the audited financial statements and notes thereto included in our Company’s annual report on Form 10-K for the year ended December 31, 2013 (2013 Form 10-K).
	The December 31, 2013 financial position data included herein is derived from the audited consolidated financial statements included in the 2013 Form 10-K but does not include all disclosures required by U.S. GAAP.
	B.  Nature of Operations
	Information in our financial statements and related commentary are presented in the following categories:
	Machinery, Energy & Transportation – Represents the aggregate total of Construction Industries, Resource Industries, Energy & Transportation, and All Other operating segments and related corporate items and eliminations.
	Financial Products – Primarily includes the company’s Financial Products Segment.  This category includes Caterpillar Financial Services Corporation (Cat Financial), Caterpillar Financial Insurance Services (Insurance Services) and their respective subsidiaries.

Accounting Changes and Error Corrections [Abstract]	'
New Accounting Guidance	'
	New Accounting Guidance
	Joint and several liability arrangements – In February 2013, the Financial Accounting Standards Board (FASB) issued accounting guidance on the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements. The guidance requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The entity is also required to disclose the nature and amount of the obligation as well as any other information about those obligations. This guidance was effective January 1, 2014, with retrospective application required. The guidance did not have a material impact on our financial statements.
	Parent's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity – In March 2013, the FASB issued accounting guidance on the parent's accounting for the cumulative translation adjustment (CTA) upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. The new standard clarifies existing guidance regarding when the CTA should be released into earnings upon various deconsolidation and consolidation transactions. This guidance was effective January 1, 2014. The guidance did not have a material impact on our financial statements.
	Presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists – In July 2013, the FASB issued accounting guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance requires an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward in the financial statements if available under the applicable tax jurisdiction. The guidance was effective January 1, 2014. The guidance did not have a material impact on our financial statements.
	Reporting discontinued operations and disclosures of disposals of components of an entity – In April 2014, the FASB issued accounting guidance for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The guidance defines a discontinued operation as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. This guidance is effective January 1, 2015. We do not expect the adoption to have a material impact on our financial statements.
	Revenue recognition – In May 2014, the FASB issued new revenue recognition guidance to provide a single, comprehensive revenue recognition model for all contracts with customers. Under the new guidance, an entity will recognize revenue to depict the transfer of promised goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. A five step model has been introduced for an entity to apply when recognizing revenue. The new guidance also includes enhanced disclosure requirements, and is effective January 1, 2017. Entities have the option to apply the new guidance under a retrospective approach to each prior reporting period presented, or a modified retrospective approach with the cumulative effect of initially applying the new guidance recognized at the date of initial application within the Consolidated Statement of Changes in Stockholders' Equity. We are in the process of evaluating the application and implementation of the new guidance.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]	'
Stock-Based Compensation	'
	Stock-Based Compensation
	Accounting for stock-based compensation requires that the cost resulting from all stock-based payments be recognized in the financial statements based on the grant date fair value of the award.  Stock-based compensation primarily consists of stock options, restricted stock units (RSUs) and stock-settled stock appreciation rights (SARs).  We recognized pretax stock-based compensation cost in the amount of $84 million and $137 million for the three and six months ended June 30, 2014, respectively; and $83 million and $132 million for the three and six months ended and June 30, 2013, respectively.
	The following table illustrates the type and fair value of the stock-based compensation awards granted during the six month periods ended June 30, 2014 and 2013, respectively:
		2014				2013
		Shares Granted		Fair Value		Shares Granted	Fair Value
				Per Award			Per Award
	Stock options	4,448,218		$	29.52	4,276,060	$	28.34
	RSUs	1,429,512		$	89.18	1,614,870	$	84.05
	The stock price on the date of grant was $96.31 and $89.75 for 2014 and 2013, respectively.
	The following table provides the assumptions used in determining the fair value of the stock-based awards for the six month periods ended June 30, 2014 and 2013, respectively:
		Grant Year
		2014	2013
	Weighted-average dividend yield	2.15%	2.13%
	Weighted-average volatility	28.20%	30.60%

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Financial Instruments and Risk Management	'
	Derivative Financial Instruments and Risk Management
	Our earnings and cash flow are subject to fluctuations due to changes in foreign currency exchange rates, interest rates and commodity prices.  Our Risk Management Policy (policy) allows for the use of derivative financial instruments to prudently manage foreign currency exchange rate, interest rate and commodity price exposures.  Our policy specifies that derivatives are not to be used for speculative purposes.  Derivatives that we use are primarily foreign currency forward, option, and cross currency contracts, interest rate swaps, and commodity forward and option contracts.  Our derivative activities are subject to the management, direction and control of our senior financial officers.  Risk management practices, including the use of financial derivative instruments, are presented to the Audit Committee of the Board of Directors at least annually.
	All derivatives are recognized on the Consolidated Statement of Financial Position at their fair value. On the date the derivative contract is entered into, we designate the derivative as (1) a hedge of the fair value of a recognized asset or liability (fair value hedge), (2) a hedge of a forecasted transaction or the variability of cash flow to be paid (cash flow hedge), or (3) an undesignated instrument. Changes in the fair value of a derivative that is qualified, designated and highly effective as a fair value hedge, along with the gain or loss on the hedged recognized asset or liability that is attributable to the hedged risk, are recorded in current earnings. Changes in the fair value of a derivative that is qualified, designated and highly effective as a cash flow hedge are recorded in Accumulated other comprehensive income (loss) (AOCI), to the extent effective, on the Consolidated Statement of Financial Position until they are reclassified to earnings in the same period or periods during which the hedged transaction affects earnings.  Changes in the fair value of undesignated derivative instruments and the ineffective portion of designated derivative instruments are reported in current earnings. Cash flow from designated derivative financial instruments are classified within the same category as the item being hedged on the Consolidated Statement of Cash Flow.  Cash flow from undesignated derivative financial instruments are included in the investing category on the Consolidated Statement of Cash Flow.
	We formally document all relationships between hedging instruments and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions.  This process includes linking all derivatives that are designated as fair value hedges to specific assets and liabilities on the Consolidated Statement of Financial Position and linking cash flow hedges to specific forecasted transactions or variability of cash flow.
	We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the designated derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flow of hedged items.  When a derivative is determined not to be highly effective as a hedge or the underlying hedged transaction is no longer probable, we discontinue hedge accounting prospectively, in accordance with the derecognition criteria for hedge accounting.
	Foreign Currency Exchange Rate Risk
	Foreign currency exchange rate movements create a degree of risk by affecting the U.S. dollar value of sales made and costs incurred in foreign currencies. Movements in foreign currency rates also affect our competitive position as these changes may affect business practices and/or pricing strategies of non-U.S.-based competitors. Additionally, we have balance sheet positions denominated in foreign currencies, thereby creating exposure to movements in exchange rates.
	Our Machinery, Energy & Transportation operations purchase, manufacture and sell products in many locations around the world. As we have a diversified revenue and cost base, we manage our future foreign currency cash flow exposure on a net basis. We use foreign currency forward and option contracts to manage unmatched foreign currency cash inflow and outflow. Our objective is to minimize the risk of exchange rate movements that would reduce the U.S. dollar value of our foreign currency cash flow. Our policy allows for managing anticipated foreign currency cash flow for up to five years.
	We generally designate as cash flow hedges at inception of the contract any Australian dollar, Brazilian real, British pound, Canadian dollar, Chinese yuan, euro, Indian rupee, Japanese yen, Mexican peso, Singapore dollar or Swiss franc forward or option contracts that meet the requirements for hedge accounting and the maturity extends beyond the current quarter-end. Designation is performed on a specific exposure basis to support hedge accounting. The remainder of Machinery, Energy & Transportation foreign currency contracts are undesignated, including any hedges designed to protect our competitive exposure.
	As of June 30, 2014, $13 million of deferred net gains, net of tax, included in equity (AOCI in the Consolidated Statement of Financial Position), are expected to be reclassified to current earnings (Other income (expense) in the Consolidated Statement of Results of Operations) over the next twelve months when earnings are affected by the hedged transactions.  The actual amount recorded in Other income (expense) will vary based on exchange rates at the time the hedged transactions impact earnings.
	In managing foreign currency risk for our Financial Products operations, our objective is to minimize earnings volatility resulting from conversion and the remeasurement of net foreign currency balance sheet positions, and future transactions denominated in foreign currencies. Our policy allows the use of foreign currency forward, option and cross currency contracts to offset the risk of currency mismatch between our receivables and debt, and exchange rate risk associated with future transactions denominated in foreign currencies. Substantially all such foreign currency forward, option and cross currency contracts are undesignated.
	Interest Rate Risk
	Interest rate movements create a degree of risk by affecting the amount of our interest payments and the value of our fixed-rate debt. Our practice is to use interest rate derivatives to manage our exposure to interest rate changes and, in some cases, lower the cost of borrowed funds.
	Our Machinery, Energy & Transportation operations generally use fixed-rate debt as a source of funding.  Our objective is to minimize the cost of borrowed funds.  Our policy allows us to enter into fixed-to-floating interest rate swaps and forward rate agreements to meet that objective. We designate fixed-to-floating interest rate swaps as fair value hedges at inception of the contract, and we designate certain forward rate agreements as cash flow hedges at inception of the contract.
	As of June 30, 2014, $4 million of deferred net losses, net of tax, included in equity (AOCI in the Consolidated Statement of Financial Position), related to Machinery, Energy & Transportation forward rate agreements, are expected to be reclassified to current earnings (Interest expense excluding Financial Products in the Consolidated Statement of Results of Operations) over the next twelve months.
	Financial Products operations has a match-funding policy that addresses interest rate risk by aligning the interest rate profile (fixed or floating rate) of Cat Financial’s debt portfolio with the interest rate profile of their receivables portfolio within predetermined ranges on an ongoing basis. In connection with that policy, we use interest rate derivative instruments to modify the debt structure to match assets within the receivables portfolio. This matched funding reduces the volatility of margins between interest-bearing assets and interest-bearing liabilities, regardless of which direction interest rates move.
	Our policy allows us to use fixed-to-floating, floating-to-fixed, and floating-to-floating interest rate swaps to meet the match-funding objective.  We designate fixed-to-floating interest rate swaps as fair value hedges to protect debt against changes in fair value due to changes in the benchmark interest rate.  We designate most floating-to-fixed interest rate swaps as cash flow hedges to protect against the variability of cash flows due to changes in the benchmark interest rate.
	As of June 30, 2014, $4 million of deferred net losses, net of tax, included in equity (AOCI in the Consolidated Statement of Financial Position), related to Financial Products floating-to-fixed interest rate swaps, are expected to be reclassified to current earnings (Interest expense of Financial Products in the Consolidated Statement of Results of Operations) over the next twelve months.  The actual amount recorded in Interest expense of Financial Products will vary based on interest rates at the time the hedged transactions impact earnings.
	We have, at certain times, liquidated fixed-to-floating and floating-to-fixed interest rate swaps at both Machinery, Energy & Transportation and Financial Products.  The gains or losses associated with these swaps at the time of liquidation are amortized into earnings over the original term of the previously designated hedged item.
	Commodity Price Risk
	Commodity price movements create a degree of risk by affecting the price we must pay for certain raw material. Our policy is to use commodity forward and option contracts to manage the commodity risk and reduce the cost of purchased materials.
	Our Machinery, Energy & Transportation operations purchase base and precious metals embedded in the components we purchase from suppliers.  Our suppliers pass on to us price changes in the commodity portion of the component cost. In addition, we are subject to price changes on energy products such as natural gas and diesel fuel purchased for operational use.
	Our objective is to minimize volatility in the price of these commodities. Our policy allows us to enter into commodity forward and option contracts to lock in the purchase price of a portion of these commodities within a five-year horizon. All such commodity forward and option contracts are undesignated.

We enter into International Swaps and Derivatives Association (ISDA) master netting agreements within Machinery, Energy & Transportation and Financial Products that permit the net settlement of amounts owed under their respective derivative contracts. Under these master netting agreements, net settlement generally permits the company or the counterparty to determine the net amount payable for contracts due on the same date and in the same currency for similar types of derivative transactions. The master netting agreements generally also provide for net settlement of all outstanding contracts with a counterparty in the case of an event of default or a termination event.
Collateral is generally not required of the counterparties or of our company under the master netting agreements. As of June 30, 2014 and December 31, 2013, no cash collateral was received or pledged under the master netting agreements.
The effect of the net settlement provisions of the master netting agreements on our derivative balances upon an event of default or termination event is as follows:

	B.  Goodwill
	We test goodwill for impairment annually and whenever events or circumstances make it more likely than not that an impairment may have occurred. We perform our annual goodwill impairment test as of October 1 and monitor for interim triggering events on an ongoing basis. Goodwill is reviewed for impairment utilizing a qualitative assessment or a two-step process. We have an option to make a qualitative assessment of a reporting unit's goodwill for impairment. If we choose to perform a qualitative assessment and determine the fair value more likely than not exceeds the carrying value, no further evaluation is necessary. For reporting units where we perform the two-step process, the first step requires us to compare the fair value of each reporting unit, which we primarily determine using an income approach based on the present value of discounted cash flows, to the respective carrying value, which includes goodwill. If the fair value of the reporting unit exceeds its carrying value, the goodwill is not considered impaired. If the carrying value is higher than the fair value, there is an indication that an impairment may exist and the second step is required. In step two, the implied fair value of goodwill is calculated as the excess of the fair value of a reporting unit over the fair values assigned to its assets and liabilities. If the implied fair value of goodwill is less than the carrying value of the reporting unit's goodwill, the difference is recognized as an impairment loss. No goodwill for reporting units was impaired during the three and six months ended June 30, 2014 or 2013.
	As discussed in Note 15, effective January 1, 2014, we revised our reportable segments in line with the changes to our organizational structure. Our reporting units did not significantly change as a result of the changes to our reportable segments. The segment information for 2013 has been retrospectively adjusted to conform to the 2014 presentation.

	Corporate Bonds.  The unrealized losses on our investments in asset-backed securities relate to changes in interest rates and credit-related yield spreads since time of purchase.  We do not intend to sell the investments and it is not likely that we will be required to sell the investments before recovery of their amortized cost basis.  We do not consider these investments to be other-than-temporarily impaired as of June 30, 2014.
	Mortgage-Backed Debt Securities.  The unrealized losses on our investments in mortgage-backed securities relate to changes in interest rates and credit-related yield spreads since time of purchase.  We do not intend to sell the investments and it is not likely that we will be required to sell these investments before recovery of their amortized cost basis.  We do not consider these investments to be other-than-temporarily impaired as of June 30, 2014.
	Equity Securities.  Insurance Services maintains a well-diversified equity portfolio consisting of two specific mandates:  large capitalization value stocks and smaller company growth stocks.  U.S. equity valuations were higher during the second quarter of 2014 on generally favorable economic data.  The unrealized losses on our investments in equity securities relate to inherent risks of individual holdings and/or their respective sectors. We do not consider these investments to be other-than-temporarily impaired as of June 30, 2014.

Guarantees and Product Warranty	6 Months Ended
	Jun. 30, 2014
Commitments and Contingencies Disclosure [Abstract]	'
Guarantees and Product Warranty	'
	Guarantees and Product Warranty
	We have provided an indemnity to a third-party insurance company for potential losses related to performance bonds issued on behalf of Caterpillar dealers.  The bonds are issued to insure governmental agencies against nonperformance by certain dealers.  We also provided guarantees to a third-party related to the performance of contractual obligations by certain Caterpillar dealers. The guarantees cover potential financial losses incurred by the third-party resulting from the dealers’ nonperformance.
	We provide loan guarantees to third-party lenders for financing associated with machinery purchased by customers. These guarantees have varying terms and are secured by the machinery. In addition, Cat Financial participates in standby letters of credit issued to third parties on behalf of their customers. These standby letters of credit have varying terms and beneficiaries and are secured by customer assets.
	We have provided a guarantee to one of our customers in Brazil related to the performance of contractual obligations by a supplier consortium to which one of our Caterpillar subsidiaries is a member. The guarantees cover potential damages (some of them capped) incurred by the customer resulting from the supplier consortium’s non-performance. The guarantee will expire when the supplier consortium performs all its contractual obligations, which is expected to be completed in 2025.
	We have provided guarantees to third-party lessors for certain properties leased by Cat Logistics Services, LLC, in which we sold a 65 percent equity interest in the third quarter of 2012. The guarantees are for the possibility that the third party logistics business would default on real estate lease payments. The guarantees were granted at lease inception, which was prior to the divestiture, and generally will expire at the end of the lease terms.
	No significant loss has been experienced or is anticipated under any of these guarantees.  At June 30, 2014 and December 31, 2013, the related liability was $12 million and $13 million, respectively. The maximum potential amount of future payments (undiscounted and without reduction for any amounts that may possibly be recovered under recourse or collateralized provisions) we could be required to make under the guarantees are as follows:
	(Millions of dollars)	June 30,			December 31,
		2014			2013
	Caterpillar dealer guarantees	$	201		$	193
	Customer guarantees	58			62
	Customer guarantees – supplier consortium	362			364
	Third party logistics business guarantees	140			151
	Other guarantees	34			35
	Total guarantees	$	795		$	805
	Cat Financial provides guarantees to repurchase certain loans of Caterpillar dealers from a special-purpose corporation (SPC) that qualifies as a variable interest entity.  The purpose of the SPC is to provide short-term working capital loans to Caterpillar dealers.  This SPC issues commercial paper and uses the proceeds to fund its loan program.  Cat Financial has a loan purchase agreement with the SPC that obligates Cat Financial to purchase certain loans that are not paid at maturity.  Cat Financial receives a fee for providing this guarantee, which provides a source of liquidity for the SPC.  Cat Financial is the primary beneficiary of the SPC as its guarantees result in Cat Financial having both the power to direct the activities that most significantly impact the SPC’s economic performance and the obligation to absorb losses, and therefore Cat Financial has consolidated the financial statements of the SPC.  As of June 30, 2014 and December 31, 2013, the SPC’s assets of $1,186 million and $1,005 million, respectively, are primarily comprised of loans to dealers and the SPC’s liabilities of $1,185 million and $1,005 million, respectively, are primarily comprised of commercial paper.  The assets of the SPC are not available to pay Cat Financial's creditors. Cat Financial may be obligated to perform under the guarantee if the SPC experiences losses. No loss has been experienced or is anticipated under this loan purchase agreement.
	Our product warranty liability is determined by applying historical claim rate experience to the current field population and dealer inventory.  Generally, historical claim rates are based on actual warranty experience for each product by machine model/engine size by customer or dealer location (inside or outside North America).  Specific rates are developed for each product shipment month and are updated monthly based on actual warranty claim experience.

For the three and six months ended June 30, 2013, there were outstanding SARs and stock options to purchase 10,350,280 and 10,256,295 common shares which were anti-dilutive.
	In February 2007, the Board of Directors authorized the repurchase of $7.5 billion of Caterpillar common stock (the 2007 Authorization), and in December 2011, the 2007 Authorization was extended through December 2015. In April 2013, we entered into a definitive agreement with Citibank, N.A. to purchase shares of our common stock under an accelerated stock repurchase transaction (April 2013 ASR Agreement), which was completed in June 2013. In accordance with the terms of the April 2013 ASR Agreement, a total of 11.5 million shares of our common stock were repurchased at an aggregate cost to Caterpillar of $1.0 billion.
	In January 2014, we completed the 2007 Authorization and entered into a definitive agreement with Citibank, N.A. to purchase shares of our common stock under an accelerated stock repurchase transaction (January 2014 ASR Agreement), which was completed in March 2014. In accordance with the terms of the January 2014 ASR Agreement, a total of approximately 18.1 million shares of our common stock were repurchased at an aggregate cost to Caterpillar of approximately $1.7 billion.
	In January 2014, the Board approved a new authorization to repurchase up to $10 billion of Caterpillar common stock, which will expire on December 31, 2018. In July 2014, we entered into definitive agreements with Société Générale to purchase shares of our common stock under accelerated stock repurchase transactions (July 2014 ASR Agreements). Pursuant to the terms of the July 2014 ASR Agreements, we have agreed to repurchase a total of $2.5 billion of our common stock from Société Générale, with an immediate delivery of approximately 22 million shares. The final number of shares to be repurchased and the aggregate cost per share to Caterpillar will be based on Caterpillar's volume-weighted average stock price during the term of the transactions, which are expected to be completed in September 2014.

Environmental Remediation Obligations [Abstract]	'
Environmental and Legal Matters	'
	Environmental and Legal Matters
	The company is regulated by federal, state and international environmental laws governing our use, transport and disposal of substances and control of emissions. In addition to governing our manufacturing and other operations, these laws often impact the development of our products, including, but not limited to, required compliance with air emissions standards applicable to internal combustion engines. We have made, and will continue to make, significant research and development and capital expenditures to comply with these emissions standards.
	We are engaged in remedial activities at a number of locations, often with other companies, pursuant to federal and state laws.  When it is probable we will pay remedial costs at a site, and those costs can be reasonably estimated, the investigation, remediation, and operating and maintenance costs are accrued against our earnings.  Costs are accrued based on consideration of currently available data and information with respect to each individual site, including available technologies, current applicable laws and regulations, and prior remediation experience. Where no amount within a range of estimates is more likely, we accrue the minimum. Where multiple potentially responsible parties are involved, we consider our proportionate share of the probable costs. In formulating the estimate of probable costs, we do not consider amounts expected to be recovered from insurance companies or others.  We reassess these accrued amounts on a quarterly basis. The amount recorded for environmental remediation is not material and is included in Accrued expenses in the Consolidated Statement of Financial Position. There is no more than a remote chance that a material amount for remedial activities at any individual site, or at all the sites in the aggregate, will be required.
	On March 20, 2014, Brazil’s Administrative Council for Economic Defense (CADE) published a Technical Opinion which named 18 companies and over 100 individuals as defendants, including two subsidiaries of Caterpillar Inc., MGE - Equipamentos e Serviços Ferroviários Ltda. (MGE) and Caterpillar Brasil Ltda. The publication of the Technical Opinion opened CADE's official administrative investigation into allegations that the defendants participated in anticompetitive bid activity for the construction and maintenance of metro and train networks in Brazil. While companies cannot be held criminally liable for anticompetitive conduct in Brazil, criminal charges have been brought against one current and one former employee of MGE involving the same conduct alleged by CADE. The Company has responded to all requests for information from the authorities. The Company is unable to predict the outcome or reasonably estimate the potential loss; however, we currently believe that this matter will not have a material adverse effect on the Company's consolidated results of operation, financial position or liquidity.
	On February 19, 2014, Progress Rail Services Corporation (Progress Rail), a wholly-owned subsidiary of Caterpillar Inc., received information from the California Air Resources Board (CARB) Enforcement Division indicating it is contemplating an enforcement proceeding with potential monetary sanctions in excess of $100,000 in connection with a notice of violation received by Progress Rail on March 15, 2013 alleging violations of air emissions regulations applicable to compression ignition mobile cargo handling equipment operating at California ports or intermodal rail yards. Despite uncertainty regarding the applicability of these regulations, Progress Rail, in coordination with CARB, implemented certain corrective action measures. Progress Rail is cooperating with CARB to resolve this matter. The Company is unable to predict the outcome; however, we currently believe that this matter will not have a material adverse effect on the Company's consolidated results of operation, financial position or liquidity.
	On October 24, 2013, Progress Rail received a grand jury subpoena from the U.S. District Court for the Central District of California. The subpoena requests documents and information from Progress Rail, United Industries Corporation, a wholly-owned subsidiary of Progress Rail, and Caterpillar Inc. relating to allegations that Progress Rail conducted improper or unnecessary railcar inspections and repairs and improperly disposed of parts, equipment, tools and other items. In connection with this subpoena, Progress Rail was informed by the U.S. Attorney for the Central District of California that it is a target of a criminal investigation into potential violations of environmental laws and alleged improper business practices. The Company is cooperating with the authorities. The Company is unable to predict the outcome or reasonably estimate the potential loss; however, we currently believe that this matter will not have a material adverse effect on the Company's consolidated results of operation, financial position or liquidity.
	In addition, we are involved in other unresolved legal actions that arise in the normal course of business. The most prevalent of these unresolved actions involve disputes related to product design, manufacture and performance liability (including claimed asbestos and welding fumes exposure), contracts, employment issues, environmental matters or intellectual property rights.  The aggregate range of reasonably possible losses in excess of accrued liabilities, if any, associated with these unresolved legal actions is not material.  In some cases, we cannot reasonably estimate a range of loss because there is insufficient information regarding the matter.  However, there is no more than a remote chance that any liability arising from these matters would be material.  Although it is not possible to predict with certainty the outcome of these unresolved legal actions, we believe that these actions will not individually or in the aggregate have a material adverse effect on our consolidated results of operations, financial position or liquidity.

	Income Taxes
	The provision for income taxes for the first six months of 2014 reflects an estimated annual effective tax rate of 29.5 percent compared with 29 percent for the first six months of 2013, excluding the items discussed below. The increase from the full-year 2013 rate of 28.5 percent is primarily due to the expiration of the U.S. research and development tax credit.
	The provision for income taxes for the first six months of 2014 also includes a charge of $55 million to correct for an error which resulted in an understatement of tax liabilities for prior years. This error had the effect of overstating profit by $27 million and $28 million for the years ended December 31, 2013 and 2012, respectively. These amounts are not material to the financial statements of any affected period. This charge was offset by a $33 million benefit to reflect a settlement with the U.S. Internal Revenue Service (IRS) related to 1992 through 1994 which resulted in a $16 million benefit to remeasure previously unrecognized tax benefits and a $17 million benefit to adjust related interest, net of tax. The provision for income taxes for the first six months of 2013 also included a benefit of $87 million primarily related to the U.S. research and development tax credit that was retroactively extended for 2012.
	It is reasonably possible that the amount of unrecognized tax benefits will change in the next 12 months. The IRS is currently examining our U.S. tax returns for 2007 to 2009 including the impact of a loss carryback to 2005. While we have not yet received a Revenue Agent's Report generally issued at the end of the field examination process, we have received Notices of Proposed Adjustment from the IRS relating to U.S. taxation of profits earned by one of our non-U.S. subsidiaries, Caterpillar SARL, from certain parts transactions and to the disallowance of foreign tax credits incurred in connection with unrelated financings. We disagree with these proposed adjustments, which the IRS did not propose in previous audits of U.S. tax returns in which the same tax positions were taken. To the extent that adjustments are assessed upon completion of the field examination relating to these matters, we would vigorously contest the adjustments in appeals. The completion of the field examination for this audit is expected in the next 12 months. In our major non-U.S. jurisdictions, tax years are typically subject to examination for three to eight years. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on our consolidated financial position, liquidity or results of operations. Due to the uncertainty related to the timing and potential outcome of these matters, we cannot estimate the range of reasonably possible change in unrecognized tax benefits in the next 12 months.

Segment Reporting [Abstract]	'
Segment Information	'
	Segment Information
	A.	Basis for segment information
	Our Executive Office is comprised of five Group Presidents, a Senior Vice President, an Executive Vice President and a CEO. Group Presidents are accountable for a related set of end-to-end businesses that they manage.  The Senior Vice President leads the Caterpillar Enterprise System Group, which was formed during the second quarter of 2013, and the Executive Vice President leads the Law and Public Policy Division. The CEO allocates resources and manages performance at the Group President level.  As such, the CEO serves as our Chief Operating Decision Maker and operating segments are primarily based on the Group President reporting structure.
	Three of our operating segments, Construction Industries, Resource Industries and Energy & Transportation are led by Group Presidents.  One operating segment, Financial Products, is led by a Group President who has responsibility for Corporate Services.  Corporate Services is a cost center primarily responsible for the performance of certain support functions globally and to provide centralized services; it does not meet the definition of an operating segment. One Group President leads three smaller operating segments that are included in the All Other operating segments.  The Caterpillar Enterprise System Group and Law and Public Policy Division are cost centers and do not meet the definition of an operating segment.
	Effective January 1, 2014, responsibility for paving products, forestry products, industrial and waste products and tunnel boring equipment moved from Resource Industries to the All Other operating segments. The responsibility for select work tools was moved from Resource Industries to Construction Industries, and the responsibility for administration of three wholly-owned dealers in Japan moved from Construction Industries to the All Other operating segments. In addition, restructuring costs in 2013 were included in operating segments and are now a reconciling item between Segment profit and Consolidated profit before taxes. The segment information for 2013 has been retrospectively adjusted to conform to the 2014 presentation.
	B.	Description of segments
	We have seven operating segments, of which four are reportable segments.  Following is a brief description of our reportable segments and the business activities included in the All Other operating segments:
	Construction Industries:  A segment primarily responsible for supporting customers using machinery in infrastructure and building construction applications. Responsibilities include business strategy, product design, product management and development, manufacturing, marketing and sales and product support. The product portfolio includes backhoe loaders, small wheel loaders, small track-type tractors, skid steer loaders, multi-terrain loaders, mini excavators, compact wheel loaders, telehandlers, select work tools, small, medium and large track excavators, wheel excavators, medium wheel loaders, compact track loaders, medium track-type tractors, track-type loaders, motor graders and pipe layers. In addition, Construction Industries has responsibility for an integrated manufacturing cost center. Inter-segment sales are a source of revenue for this segment.
	Resource Industries:  A segment primarily responsible for supporting customers using machinery in mining and quarrying applications. Responsibilities include business strategy, product design, product management and development, manufacturing, marketing and sales and product support. The product portfolio includes large track-type tractors, large mining trucks, hard rock vehicles, longwall miners, electric rope shovels, draglines, hydraulic shovels, drills, highwall miners, large wheel loaders, off-highway trucks, articulated trucks, wheel tractor scrapers, wheel dozers, select work tools, machinery components and electronics and control systems. Resource Industries also manages areas that provide services to other parts of the company, including integrated manufacturing and research and development. In addition, segment profit includes the impact from divestiture of portions of the Bucyrus distribution business. Inter-segment sales are a source of revenue for this segment.
	Energy & Transportation (formerly Power Systems):  A segment primarily responsible for supporting customers using reciprocating engines, turbines, diesel-electric locomotives and related parts across industries serving power generation, industrial, oil and gas and transportation applications, including marine and rail-related businesses. Responsibilities include business strategy, product design, product management, development, manufacturing, marketing, sales and product support of turbines and turbine-related services, reciprocating engine powered generator sets, integrated systems used in the electric power generation industry, reciprocating engines and integrated systems and solutions for the marine and oil and gas industries; reciprocating engines supplied to the industrial industry as well as Caterpillar machinery; the business strategy, product design, product management, development, manufacturing, remanufacturing, leasing, and service of diesel-electric locomotives and components and other rail-related products and services. Inter-segment sales are a source of revenue for this segment.
	Financial Products Segment:  Provides financing to customers and dealers for the purchase and lease of Caterpillar and other equipment, as well as some financing for Caterpillar sales to dealers.  Financing plans include operating and finance leases, installment sale contracts, working capital loans and wholesale financing plans. The segment also provides various forms of insurance to customers and dealers to help support the purchase and lease of our equipment.
	All Other operating segments:  Primarily includes activities such as: the remanufacturing of Cat® engines and components and remanufacturing services for other companies as well as the business strategy, product management, development, manufacturing, marketing and product support of undercarriage, specialty products, hardened bar stock components and ground engaging tools primarily for Cat products, paving products, forestry products, industrial and waste products, and tunnel boring equipment; the product management, development, marketing, sales and product support of on-highway vocational trucks for North America; parts distribution; distribution services responsible for dealer development and administration including three wholly-owned dealers in Japan, dealer portfolio management and ensuring the most efficient and effective distribution of machines, engines and parts. Results for the All Other operating segments are included as a reconciling item between reportable segments and consolidated external reporting.
	C.	Segment measurement and reconciliations
	There are several methodology differences between our segment reporting and our external reporting.  The following is a list of the more significant methodology differences:
	•	Machinery, Energy & Transportation segment net assets generally include inventories, receivables, property, plant and equipment, goodwill, intangibles, accounts payable, and customer advances.  Liabilities other than accounts payable and customer advances are generally managed at the corporate level and are not included in segment operations.  Financial Products Segment assets generally include all categories of assets.
	•	Segment inventories and cost of sales are valued using a current cost methodology.
	•	Goodwill allocated to segments is amortized using a fixed amount based on a 20 year useful life.  This methodology difference only impacts segment assets; no goodwill amortization expense is included in segment profit. In addition, only a portion of goodwill for certain acquisitions made in 2011 or later has been allocated to segments.
	•	The present value of future lease payments for certain Machinery, Energy & Transportation operating leases is included in segment assets.  The estimated financing component of the lease payments is excluded.
	•	Currency exposures for Machinery, Energy & Transportation are generally managed at the corporate level and the effects of changes in exchange rates on results of operations within the year are not included in segment profit.  The net difference created in the translation of revenues and costs between exchange rates used for U.S. GAAP reporting and exchange rates used for segment reporting are recorded as a methodology difference.
	•	Postretirement benefit expenses are split; segments are generally responsible for service and prior service costs, with the remaining elements of net periodic benefit cost included as a methodology difference.
	•	Machinery, Energy & Transportation segment profit is determined on a pretax basis and excludes interest expense, gains and losses on interest rate swaps and other income/expense items.  Financial Products Segment profit is determined on a pretax basis and includes other income/expense items.
	Reconciling items are created based on accounting differences between segment reporting and our consolidated external reporting. Please refer to pages 37 to 43 for financial information regarding significant reconciling items.  Most of our reconciling items are self-explanatory given the above explanations.  For the reconciliation of profit, we have grouped the reconciling items as follows:
	•	Corporate costs:  These costs are related to corporate requirements and strategies that are considered to be for the benefit of the entire organization.
	•	Restructuring costs: Primarily costs for employee severance and long-lived asset impairments. A table, Reconciliation of Restructuring Costs on page 40, has been included to illustrate how segment profit would have been impacted by the restructuring costs. See Note 20 for more information.
	•	Methodology differences:  See previous discussion of significant accounting differences between segment reporting and consolidated external reporting.
	•	Timing:   Timing differences in the recognition of costs between segment reporting and consolidated external reporting.

	Cat Financial Financing Activities
	Credit quality of financing receivables and allowance for credit losses
	Cat Financial applies a systematic methodology to determine the allowance for credit losses for finance receivables.  Based upon Cat Financial’s analysis of credit losses and risk factors, portfolio segments are as follows:
	•	Customer – Finance receivables with retail customers.
	•	Dealer – Finance receivables with Caterpillar dealers.
	Cat Financial further evaluates portfolio segments by the class of finance receivables, which is defined as a level of information (below a portfolio segment) in which the finance receivables have the same initial measurement attribute and a similar method for assessing and monitoring credit risk.  Typically, Cat Financial’s finance receivables within a geographic area have similar credit risk profiles and methods for assessing and monitoring credit risk.  Cat Financial’s classes, which align with management reporting for credit losses, are as follows:
	•	North America – Finance receivables originated in the United States or Canada.
	•	Europe – Finance receivables originated in Europe, Africa, Middle East and the Commonwealth of Independent States.
	•	Asia Pacific – Finance receivables originated in Australia, New Zealand, China, Japan, South Korea and Southeast Asia.
	•	Mining – Finance receivables related to large mining customers worldwide.
	•	Latin America – Finance receivables originated in Central and South American countries and Mexico.
	•	Caterpillar Power Finance – Finance receivables related to marine vessels with Caterpillar engines worldwide and Caterpillar electrical power generation, gas compression and co-generation systems and non-Caterpillar equipment that is powered by these systems worldwide.
	Impaired loans and finance leases
	For all classes, a loan or finance lease is considered impaired, based on current information and events, if it is probable that Cat Financial will be unable to collect all amounts due according to the contractual terms of the loan or finance lease.  Loans and finance leases reviewed for impairment include loans and finance leases that are past due, non-performing or in bankruptcy. Recognition of income is suspended and the loan or finance lease is placed on non-accrual status when management determines that collection of future income is not probable (generally after 120 days past due except in locations where local regulatory requirements dictate a different method, or in instances in which relevant information is known that warrants placing the loan or finance lease on non-accrual status).  Accrual is resumed, and previously suspended income is recognized, when the loan or finance lease becomes contractually current and/or collection doubts are removed.  Cash receipts on impaired loans or finance leases are recorded against the receivable and then to any unrecognized income.
	There were no impaired loans or finance leases as of June 30, 2014 or December 31, 2013, for the Dealer portfolio segment.  The average recorded investment for impaired loans and finance leases for the Dealer portfolio segment was zero for the three and six months ended June 30, 2014 and 2013.
	Individually impaired loans and finance leases for the Customer portfolio segment were as follows:

Non-accrual and past due loans and finance leases
For all classes, Cat Financial considers a loan or finance lease past due if any portion of a contractual payment is due and unpaid for more than 30 days.  Recognition of income is suspended and the loan or finance lease is placed on non-accrual status when management determines that collection of future income is not probable (generally after 120 days past due except in locations where local regulatory requirements dictate a different method, or in instances in which relevant information is known that warrants placing the loan or finance lease on non-accrual status).  Accrual is resumed, and previously suspended income is recognized, when the loan or finance lease becomes contractually current and/or collection doubts are removed.
As of June 30, 2014 and December 31, 2013, there were no loans or finance leases on non-accrual status for the Dealer portfolio segment.

Credit quality of finance receivables
The credit quality of finance receivables is reviewed on a monthly basis.  Credit quality indicators include performing and non-performing.  Non-performing is defined as finance receivables currently over 120 days past due and/or on non-accrual status or in bankruptcy.  Finance receivables not meeting the criteria listed above are considered performing.  Non-performing receivables have the highest probability for credit loss.  The allowance for credit losses attributable to non-performing receivables is based on the most probable source of repayment, which is normally the liquidation of collateral.  In determining collateral value, Cat Financial estimates the current fair market value of the collateral less selling costs. In addition, Cat Financial considers credit enhancements such as additional collateral and contractual third-party guarantees in determining the allowance for credit losses attributable to non-performing receivables.

Troubled Debt Restructurings
A restructuring of a loan or finance lease receivable constitutes a troubled debt restructuring (TDR) when the lender grants a concession it would not otherwise consider to a borrower experiencing financial difficulties.  Concessions granted may include extended contract maturities, inclusion of interest only periods, below market interest rates, extended skip payment periods and reduction of principal and/or accrued interest.
TDRs are reviewed along with other receivables as part of management’s ongoing evaluation of the adequacy of the allowance for credit losses.  The allowance for credit losses attributable to TDRs is based on the most probable source of repayment, which is normally the liquidation of collateral.  In determining collateral value, Cat Financial estimates the current fair market value of the collateral less selling costs. In addition, Cat Financial considers credit enhancements such as additional collateral and contractual third-party guarantees in determining the allowance for credit losses attributable to TDRs.
There were no loans or finance lease receivables modified as TDRs during the three and six months ended June 30, 2014 or 2013 for the Dealer portfolio segment.
Loan and finance lease receivables in the Customer portfolio segment modified as TDRs during the three and six months ended June 30, 2014 and 2013, were as follows:

1	During the three and six months ended June 30, 2014, there were no additional funds subsequently loaned to a borrower whose terms had been modified in a TDR. During the three and six months ended June 30, 2013, $7 million and $12 million, respectively, of additional funds were subsequently loaned to a borrower whose terms had been modified in a TDR.  The $7 million and $12 million of additional funds are not reflected in the table above as no incremental modifications have been made with the borrower during the period presented.  At June 30, 2014, remaining commitments to lend additional funds to a borrower whose terms have been modified in a TDR were $2 million.
2	Modifications include extended contract maturities, inclusion of interest only periods, below market interest rates, extended skip payment periods and reduction of principal and/or accrued interest.

	Fair Value Measurements
	A. Fair value measurements
	The guidance on fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants.  This guidance also specifies a fair value hierarchy based upon the observability of inputs used in valuation techniques.  Observable inputs (highest level) reflect market data obtained from independent sources, while unobservable inputs (lowest level) reflect internally developed market assumptions.  In accordance with this guidance, fair value measurements are classified under the following hierarchy:
	•	Level 1 – Quoted prices for identical instruments in active markets.
	•	Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable in active markets.
	•	Level 3 – Model-derived valuations in which one or more significant inputs or significant value-drivers are unobservable.
	When available, we use quoted market prices to determine fair value, and we classify such measurements within Level 1.  In some cases where market prices are not available, we make use of observable market based inputs to calculate fair value, in which case the measurements are classified within Level 2.  If quoted or observable market prices are not available, fair value is based upon internally developed models that use, where possible, current market-based parameters such as interest rates, yield curves and currency rates.  These measurements are classified within Level 3.
	Fair value measurements are classified according to the lowest level input or value-driver that is significant to the valuation.  A measurement may therefore be classified within Level 3 even though there may be significant inputs that are readily observable.
	Fair value measurement includes the consideration of nonperformance risk.  Nonperformance risk refers to the risk that an obligation (either by a counterparty or Caterpillar) will not be fulfilled.  For financial assets traded in an active market (Level 1 and certain Level 2), the nonperformance risk is included in the market price.  For certain other financial assets and liabilities (certain Level 2 and Level 3), our fair value calculations have been adjusted accordingly.
	Available-for-sale securities
	Our available-for-sale securities, primarily at Insurance Services, include a mix of equity and debt instruments (see Note 8 for additional information).  Fair values for our U.S. treasury bonds and equity securities are based upon valuations for identical instruments in active markets.  Fair values for other government bonds, corporate bonds and mortgage-backed debt securities are based upon models that take into consideration such market-based factors as recent sales, risk-free yield curves and prices of similarly rated bonds.
	Derivative financial instruments
	The fair value of interest rate swap derivatives is primarily based on models that utilize the appropriate market-based forward swap curves and zero-coupon interest rates to determine discounted cash flows.  The fair value of foreign currency and commodity forward, option and cross currency contracts is based on a valuation model that discounts cash flows resulting from the differential between the contract price and the market-based forward rate.
	Guarantees
	The fair value of guarantees is based upon our estimate of the premium a market participant would require to issue the same guarantee in a stand-alone arms-length transaction with an unrelated party. If quoted or observable market prices are not available, fair value is based upon internally developed models that utilize current market-based assumptions.
	Assets and liabilities measured on a recurring basis at fair value, primarily related to Financial Products, included in our Consolidated Statement of Financial Position as of June 30, 2014 and December 31, 2013 are summarized below:

In addition to the amounts above, Cat Financial impaired loans are subject to measurement at fair value on a nonrecurring basis. A loan is considered impaired when management determines that collection of contractual amounts due is not probable.  In these cases, an allowance for credit losses may be established based primarily on the fair value of associated collateral.  As the collateral’s fair value is based on observable market prices and/or current appraised values, the impaired loans are classified as Level 2 measurements. Cat Financial had impaired loans with a fair value of $179 million and $81 million as of June 30, 2014 and December 31, 2013, respectively.
B. Fair values of financial instruments
In addition to the methods and assumptions we use to record the fair value of financial instruments as discussed in the Fair value measurements section above, we used the following methods and assumptions to estimate the fair value of our financial instruments:
Cash and short-term investments
Carrying amount approximated fair value.
Restricted cash and short-term investments
Carrying amount approximated fair value.  Restricted cash and short-term investments are included in Prepaid expenses and other current assets in the Consolidated Statement of Financial Position.
Finance receivables
Fair value was estimated by discounting the future cash flows using current rates, representative of receivables with similar remaining maturities.
Wholesale inventory receivables
Fair value was estimated by discounting the future cash flows using current rates, representative of receivables with similar remaining maturities.
Short-term borrowings
Carrying amount approximated fair value.
Long-term debt
Fair value for fixed and floating rate debt was estimated based on quoted market prices.
Please refer to the table below for the fair values of our financial instruments.

	Acquisitions
	ERA Mining Machinery Limited (Siwei)
	During the second quarter of 2012, Caterpillar, through its wholly-owned subsidiary Caterpillar (Luxembourg) Investment Co. S.A. (CAT Lux), completed a tender offer to acquire the issued shares of ERA Mining Machinery Limited (Siwei), including its wholly-owned subsidiary Zhengzhou Siwei Mechanical Manufacturing Co., Ltd. In the fourth quarter of 2013, Siwei was renamed Caterpillar (Zhengzhou) Ltd. The tender offer allowed Siwei shareholders to choose between two types of consideration in exchange for their shares. The alternatives were either cash consideration or a loan note issued by CAT Lux to the former shareholders of Siwei. Approximately 4 billion Siwei shares were tendered for the cash alternative and approximately 1.6 billion Siwei shares were tendered for the loan note alternative.
	In May 2013, Caterpillar and its wholly-owned subsidiaries CAT Lux and Siwei entered into a settlement agreement with two former directors of Siwei and two other parties with an interest in the settlement, including Mining Machinery Limited (MML). The agreement settles the dispute between the parties which arose from Caterpillar's determination that Siwei senior managers had engaged in accounting misconduct for several years prior to Caterpillar's announcement of the completion of its tender offer for Siwei in the second quarter of 2012.
	Under the terms of the settlement agreement, the parties agreed that (i) the loan notes issued by CAT Lux (and guaranteed by Caterpillar) as a portion of the Siwei purchase price and held by MML and (ii) loans made by the two former Siwei directors to Siwei prior to its acquisition by Caterpillar would all be canceled and discharged in exchange for payments by CAT Lux to MML and the two former directors in an aggregate amount of approximately $30 million. As of the settlement in May 2013, the loan notes had a book value of approximately $152 million and the obligation related to the loans by the two former directors was approximately $13 million. The settlement agreement contains a mutual release and discharge of the parties' respective claims with respect to the dispute and contains an agreement by Caterpillar and CAT Lux not to pursue any such claims against either the auditors or former directors of Siwei. The settlement and discharge of the loan obligations resulted in the recognition of a gain of approximately $135 million reported in Other operating (income) expenses in the Consolidated Statement of Results of Operations and is included in the Resource Industries segment.

	Bucyrus Distribution Business Divestiture
	In conjunction with our acquisition of Bucyrus in July 2011, we announced our intention to sell the Bucyrus distribution business to Caterpillar dealers that support mining customers around the world in a series of individual transactions.  Bucyrus predominantly employed a direct to end customer model to sell and support products.  The intention is for all Bucyrus products to be sold and serviced by Caterpillar dealers, consistent with our long-held distribution strategy.  These transitions are occurring in phases based on the mining business opportunity within each dealer territory.
	As portions of the Bucyrus distribution business are sold or classified as held for sale, they will not qualify as discontinued operations because Caterpillar expects significant continuing direct cash flows from the Caterpillar dealers after the divestitures. The gain or loss on disposal, along with the continuing operations of these disposal groups, will be reported in the Resource Industries segment. Goodwill will be allocated to each disposal group using the relative fair value method. The value of the customer relationship intangibles related to each portion of the Bucyrus distribution business to be sold will be included in the disposal groups. The disposal groups will be recorded at the lower of their carrying value or fair value less cost to sell. In the second quarter of 2014, we recorded an impairment charge of $4 million related to disposal groups being sold to Caterpillar dealers. Fair value was determined based upon the negotiated sales price. The impairment was recorded in Other operating (income) expenses and included in the Resource Industries segment. The portions of the distribution business that were sold were not material to our results of operations, financial position or cash flow.
	We completed three sale transactions during the first quarter of 2014 and fifteen during the second quarter of 2014 whereby portions of the Bucyrus distribution business were sold to Caterpillar dealers for an aggregate price of $157 million. For the first half of 2014, after-tax profit was unfavorably impacted by $17 million as a result of the Bucyrus distribution divestiture activities. This is comprised of $18 million of income related to the sales transactions, a net unfavorable adjustment of $8 million related to prior sale transactions (both included in Other operating (income) expenses), costs incurred related to the Bucyrus distribution divestiture activities of $20 million (included in Selling, general and administrative expenses) and income tax of $7 million.
	Assets sold in the first half of 2014 primarily consisted of customer relationship intangibles of $62 million, allocated goodwill of $56 million and inventory of $12 million related to the divested portions of the Bucyrus distribution business.
	As of June 30, 2014, one divestiture transaction was classified as held for sale and is expected to close in 2014. Current assets held for sale were included in Prepaid expenses and other current assets and non-current assets held for sale were included in Other assets in the Consolidated Statement of Financial Position.
	The major classes of assets held for sale for a portion of the Bucyrus distribution business were as follows:

	Restructuring Costs
	For the three and six months ended June 30, 2014, we recognized $114 million and $263 million, respectively, of restructuring costs in Other operating (income) expenses in the Consolidated Statement of Results of Operations, which included $107 million of employee separation costs and $7 million of long-lived asset impairments and other restructuring costs for the three months ended June 30, 2014 and $249 million of employee separation costs and $14 million of long-lived asset impairments and other restructuring costs for the six months ended June 30, 2014. The restructuring costs in 2014 were primarily related to a reduction in workforce at our Gosselies, Belgium facility. For the three and six months ended June 30, 2013, we recognized $28 million and $35 million, respectively, of restructuring costs, which included $16 million of employee separation costs and $12 million of long-lived asset impairments for the three months ended June 30, 2013 and $23 million of employee separation costs and $12 million of long-lived asset impairments for the six months ended June 30, 2013. For the first six months of 2013, costs primarily related to separation programs in North America and Europe.
	Restructuring costs for the year ended December 31, 2013 were $200 million and were recognized in Other operating (income) expenses in the Consolidated Statement of Results of Operations. The 2013 restructuring costs included $151 million of employee separation costs, $41 million of long-lived asset impairments and $8 million of other restructuring costs. The most significant charges in 2013 were for the restructuring of management and support functions and the closure or downsizing of several facilities related to our mining business.
	Restructuring costs are a reconciling item between Segment profit and Consolidated profit before taxes. See Note 15 for more information.
	Our accounting for separations was dependent upon how the particular program was designed. For voluntary programs, eligible separation costs were recognized at the time of employee acceptance. For involuntary programs, eligible costs were recognized when management had approved the program, the affected employees had been properly notified and the costs were estimable.
	The following table summarizes the 2013 and 2014 employee separation activity:
	(Millions of dollars)
		Total
	Liability balance at December 31, 2012	$	29
	Increase in liability (separation charges)	151
	Reduction in liability (payments and other adjustments)	(91		)
	Liability balance at December 31, 2013	$	89
	Increase in liability (separation charges)	249
	Reduction in liability (payments and other adjustments)	(114		)
	Liability balance at June 30, 2014	$	224
	The remaining liability balances as of June 30, 2014 represent costs for employees who have not yet separated from the Company or whose full severance has not yet been paid. The majority of these remaining costs are expected to be paid in 2014.
	In December 2013, we announced a restructuring plan for our Gosselies, Belgium facility. This restructuring plan is designed to improve the competitiveness of our European manufacturing footprint and achieve competitiveness in our European operations by refocusing our current Gosselies operations on final machine assembly, test and paint with limited component and fabrication operations. This action will include reshaping our supply base for more efficient sourcing, improving factory efficiencies and workforce reductions and was approved by the Belgian Minister of Employment in February 2014. We estimate the total employee cash separation costs to be about $300 million before tax, which represents substantially all of the restructuring costs to be incurred under the restructuring plan. We expect to recognize substantially all of these separation-related charges throughout 2014. For the three and six months ended June 30, 2014, we recognized $87 million and $215 million, respectively, of employee separation costs relating to this restructuring plan. The majority of these costs will be paid throughout the remainder of 2014.

Derivative Financial Instruments and Risk Management (Policies)	6 Months Ended
	Jun. 30, 2014
Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Risk Management Policy	'
	Foreign Currency Exchange Rate Risk
	Foreign currency exchange rate movements create a degree of risk by affecting the U.S. dollar value of sales made and costs incurred in foreign currencies. Movements in foreign currency rates also affect our competitive position as these changes may affect business practices and/or pricing strategies of non-U.S.-based competitors. Additionally, we have balance sheet positions denominated in foreign currencies, thereby creating exposure to movements in exchange rates.
	Our Machinery, Energy & Transportation operations purchase, manufacture and sell products in many locations around the world. As we have a diversified revenue and cost base, we manage our future foreign currency cash flow exposure on a net basis. We use foreign currency forward and option contracts to manage unmatched foreign currency cash inflow and outflow. Our objective is to minimize the risk of exchange rate movements that would reduce the U.S. dollar value of our foreign currency cash flow. Our policy allows for managing anticipated foreign currency cash flow for up to five years.
	We generally designate as cash flow hedges at inception of the contract any Australian dollar, Brazilian real, British pound, Canadian dollar, Chinese yuan, euro, Indian rupee, Japanese yen, Mexican peso, Singapore dollar or Swiss franc forward or option contracts that meet the requirements for hedge accounting and the maturity extends beyond the current quarter-end. Designation is performed on a specific exposure basis to support hedge accounting. The remainder of Machinery, Energy & Transportation foreign currency contracts are undesignated, including any hedges designed to protect our competitive exposure.
	As of June 30, 2014, $13 million of deferred net gains, net of tax, included in equity (AOCI in the Consolidated Statement of Financial Position), are expected to be reclassified to current earnings (Other income (expense) in the Consolidated Statement of Results of Operations) over the next twelve months when earnings are affected by the hedged transactions.  The actual amount recorded in Other income (expense) will vary based on exchange rates at the time the hedged transactions impact earnings.
	In managing foreign currency risk for our Financial Products operations, our objective is to minimize earnings volatility resulting from conversion and the remeasurement of net foreign currency balance sheet positions, and future transactions denominated in foreign currencies. Our policy allows the use of foreign currency forward, option and cross currency contracts to offset the risk of currency mismatch between our receivables and debt, and exchange rate risk associated with future transactions denominated in foreign currencies. Substantially all such foreign currency forward, option and cross currency contracts are undesignated.
	Interest Rate Risk
	Interest rate movements create a degree of risk by affecting the amount of our interest payments and the value of our fixed-rate debt. Our practice is to use interest rate derivatives to manage our exposure to interest rate changes and, in some cases, lower the cost of borrowed funds.
	Our Machinery, Energy & Transportation operations generally use fixed-rate debt as a source of funding.  Our objective is to minimize the cost of borrowed funds.  Our policy allows us to enter into fixed-to-floating interest rate swaps and forward rate agreements to meet that objective. We designate fixed-to-floating interest rate swaps as fair value hedges at inception of the contract, and we designate certain forward rate agreements as cash flow hedges at inception of the contract.
	As of June 30, 2014, $4 million of deferred net losses, net of tax, included in equity (AOCI in the Consolidated Statement of Financial Position), related to Machinery, Energy & Transportation forward rate agreements, are expected to be reclassified to current earnings (Interest expense excluding Financial Products in the Consolidated Statement of Results of Operations) over the next twelve months.
	Financial Products operations has a match-funding policy that addresses interest rate risk by aligning the interest rate profile (fixed or floating rate) of Cat Financial’s debt portfolio with the interest rate profile of their receivables portfolio within predetermined ranges on an ongoing basis. In connection with that policy, we use interest rate derivative instruments to modify the debt structure to match assets within the receivables portfolio. This matched funding reduces the volatility of margins between interest-bearing assets and interest-bearing liabilities, regardless of which direction interest rates move.
	Our policy allows us to use fixed-to-floating, floating-to-fixed, and floating-to-floating interest rate swaps to meet the match-funding objective.  We designate fixed-to-floating interest rate swaps as fair value hedges to protect debt against changes in fair value due to changes in the benchmark interest rate.  We designate most floating-to-fixed interest rate swaps as cash flow hedges to protect against the variability of cash flows due to changes in the benchmark interest rate.
	As of June 30, 2014, $4 million of deferred net losses, net of tax, included in equity (AOCI in the Consolidated Statement of Financial Position), related to Financial Products floating-to-fixed interest rate swaps, are expected to be reclassified to current earnings (Interest expense of Financial Products in the Consolidated Statement of Results of Operations) over the next twelve months.  The actual amount recorded in Interest expense of Financial Products will vary based on interest rates at the time the hedged transactions impact earnings.
	We have, at certain times, liquidated fixed-to-floating and floating-to-fixed interest rate swaps at both Machinery, Energy & Transportation and Financial Products.  The gains or losses associated with these swaps at the time of liquidation are amortized into earnings over the original term of the previously designated hedged item.
	Commodity Price Risk
	Commodity price movements create a degree of risk by affecting the price we must pay for certain raw material. Our policy is to use commodity forward and option contracts to manage the commodity risk and reduce the cost of purchased materials.
	Our Machinery, Energy & Transportation operations purchase base and precious metals embedded in the components we purchase from suppliers.  Our suppliers pass on to us price changes in the commodity portion of the component cost. In addition, we are subject to price changes on energy products such as natural gas and diesel fuel purchased for operational use.
	Our objective is to minimize volatility in the price of these commodities. Our policy allows us to enter into commodity forward and option contracts to lock in the purchase price of a portion of these commodities within a five-year horizon. All such commodity forward and option contracts are undesignated.
