SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION. C.H. Robinson Worldwide, Inc. and our subsidiaries (“the company,” “we,” “us,” or “our”) are a global provider of transportation services and logistics solutions through a network of offices operating in North America, Europe, Asia, Oceania, and South America. The consolidated financial statements include the accounts of C.H. Robinson Worldwide, Inc. and our majority owned and controlled subsidiaries. Our minority interests in subsidiaries are not significant. All intercompany transactions and balances have been eliminated in the consolidated financial statements. USE OF ESTIMATES. The preparation of financial statements, in conformity with accounting principles generally accepted in the United States, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates have been prepared on the basis of the most current and best information, and our actual results could differ materially from those estimates. REVENUE RECOGNITION. At contract inception, we assess the goods and services promised in our contracts with customers and identify our performance obligations to provide distinct goods and services to our customers. We have determined that the following distinct goods and services represent our primary performance obligations. Transportation and Logistics Services - As a third party logistics provider, our primary performance obligation under our customer contracts is to utilize our relationships with a wide variety of transportation companies to efficiently and cost-effectively transport our customers’ freight. Revenue is recognized for these performance obligations as they are satisfied over the contract term, which generally represents the transit period. The transit period can vary based upon the method of transport, generally a number of days for over the road, rail, and air transportation, or several weeks in the case of an ocean shipment. Determining the transit period and how much of it has been completed as of the reporting date may require management to make judgments that affect the timing of revenue recognized. When the customers’ freight reaches its intended destination our performance obligation is complete. Pricing for our services is generally a fixed amount and is typically due within 30 days upon completion of our performance obligation. We also provide certain value-added logistics services, such as customs brokerage, fee-based managed services, warehousing services, small parcel, and supply chain consulting and optimization services. These services may include one or more performance obligations which are generally satisfied over the service period as we perform our obligations. The service period may be a very short duration, in the case of customs brokerage and small parcel, or it may be longer in the case of warehousing, managed services and supply chain consulting and optimization services. Pricing for our services is established in the customer contract and is dependent upon the specific needs of the customer but may be agreed upon at a fixed fee per transaction, labor hour, or service period. Payment is typically due within 30 days upon completion of our performance obligation. Sourcing Services - We contract with grocery retailers, restaurants, foodservice distributors, and produce wholesalers to provide sourcing services under the trade name Robinson Fresh. Our primary service obligation under these contracts is the buying, selling, and/or marketing of produce including fresh fruits, vegetables, and other value-added perishable items. Revenue is recognized when our performance obligations under these contracts is satisfied at a point in time, generally when the produce is received by our customer. Pricing under these contracts is generally a fixed amount and is typically due within 30 days upon completion of our performance obligation. In many cases, as additional performance obligations, we contract to arrange logistics and transportation of the products we buy, sell, and/or market. These performance obligations are satisfied over the contract term consistent with our other transportation and logistics services. The contract period is typically less than one year. Pricing for our services is generally a fixed amount and is typically due within 30 days upon completion of our performance obligation. Total revenues represent the total dollar value of revenue recognized from contracts with customers for the goods and services we provide. Substantially all of our revenue is attributable to contracts with our customers. Our net revenues are our total revenues less purchased transportation and related services, including contracted motor carrier, rail, ocean, air, and other costs, and the purchase price and services related to the products we source. Most transactions in our transportation and sourcing businesses are recorded at the gross amount we charge our customers for the service we provide and goods we sell. In these transactions, we are primarily responsible for fulfilling the promise to provide the specified good or service to our customer and we have discretion in establishing the price for the specified good or service. Additionally, in our sourcing business, in some cases we take inventory risk before the specified good has been transferred to our customer. Customs brokerage, managed services, freight forwarding, and sourcing managed procurement transactions are recorded at the net amount we charge our customers for the service we provide because many of the factors stated above are not present. CONTRACT ASSETS. Contract assets represent amounts for which we have the right to consideration for the services we have provided while a shipment is still in-transit but for which we have not yet completed our performance obligation or have not yet invoiced our customer. Upon completion of our performance obligations, which can vary in duration based upon the method of transport, and billing our customer these amounts become classified within accounts receivable and are then typically due within 30 days. ACCRUED TRANSPORTATION EXPENSE. Accrued transportation expense represents amounts we owe to vendors, primarily transportation providers, for the services they have provided while a shipment is still in-transit as of the reporting date. ALLOWANCE FOR DOUBTFUL ACCOUNTS. Accounts receivable are reduced by an allowance for amounts that may become uncollectible in the future. We continuously monitor payments from our customers and maintain a provision for uncollectible accounts based upon our customer aging trends, historical loss experience, and any specific customer collection issues that we have identified. FOREIGN CURRENCY. Most balance sheet accounts of foreign subsidiaries are remeasured and translated at the current exchange rate as of the end of the year. Translation adjustments are recorded in other comprehensive (loss) income. Statement of operations items are translated at the average exchange rate during the year. CASH AND CASH EQUIVALENTS. Cash and cash equivalents consist primarily of bank deposits and highly liquid investments with an original maturity of three months or less from the time of purchase. Cash and cash equivalents held outside the United States totaled $405.1 million and $320.0 million as of December 31, 2019 and 2018. The majority of our cash and cash equivalents balance is denominated in U.S. dollars although these balances are frequently held in locations where the U.S. dollar is not the functional currency. PREPAID EXPENSES AND OTHER. Prepaid expenses and other include such items as software maintenance contracts, insurance premiums, other prepaid operating expenses, and inventories, consisting primarily of produce and related products held for resale. RIGHT-OF-USE LEASE ASSETS. Right-of-use lease assets are recognized upon lease commencement and represent our right to use an underlying asset for the lease term. LEASE LIABILITIES. Lease liabilities are recognized at commencement date and represent our obligation to make the lease payments arising from a lease, measured on a discounted basis. PROPERTY AND EQUIPMENT. Property and equipment are recorded at cost. Maintenance and repair expenditures are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated lives of the assets. Amortization of leasehold improvements is computed over the shorter of the lease term or the estimated useful lives of the improvements. We recognized the following depreciation expense (in thousands): 2019 $ 45,016 2018 45,155 2017 42,817 A summary of our property and equipment as of December 31, is as follows (in thousands): 2019 2018 Furniture, fixtures, and equipment $ 283,378 $ 272,733 Buildings 112,410 130,959 Corporate aircraft 11,461 11,337 Leasehold improvements 61,539 58,929 Land 20,146 23,648 Construction in progress 1,042 1,241 Less: accumulated depreciation and amortization (281,553) (270,546) Net property and equipment $ 208,423 $ 228,301 GOODWILL. Goodwill represents the excess of the cost of acquired businesses over the net of the fair value of identifiable tangible net assets and identifiable intangible assets purchased and liabilities assumed. Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis (November 30 for us) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. See Note 2, Goodwill and Other Intangible Assets . OTHER INTANGIBLE ASSETS. Other intangible assets include definite-lived customer lists, non-competition agreements, and indefinite-lived trademarks. The definite-lived intangible assets are being amortized using the straight-line method over their estimated lives, ranging from five Goodwill and Other Intangible Assets . OTHER ASSETS. Other assets consist primarily of purchased and internally developed software, and the investments related to our nonqualified deferred compensation plan. We amortize software using the straight-line method over three years. We recognized the following amortization expense of purchased and internally developed software (in thousands): 2019 $ 17,023 2018 14,688 2017 13,887 A summary of our purchased and internally developed software as of December 31, is as follows (in thousands): 2019 2018 Purchased software $ 34,026 $ 32,460 Internally developed software 100,894 68,853 Less accumulated amortization (83,158) (66,638) Net software $ 51,762 $ 34,675 INCOME TAXES. Income taxes are accounted for using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted rates. Annual tax provisions include amounts considered sufficient to pay assessments that may result from examination of prior year tax returns; however, the amount ultimately paid upon resolution of issues raised may differ from the amounts accrued. The financial statement benefits of an uncertain income tax position are recognized when more likely than not, based on the technical merits, the position will be sustained upon examination. Unrecognized tax benefits are, more likely than not, owed to a taxing authority, and the amount of the contingency can be reasonably estimated. Uncertain income tax positions are included in “Accrued income taxes” or “Noncurrent income taxes payable” in the consolidated balance sheets. COMPREHENSIVE INCOME (LOSS). Comprehensive income (loss) consists primarily of foreign currency translation adjustments. It is presented on our consolidated statements of operations and comprehensive income gross of related income tax effects. STOCK-BASED COMPENSATION. We issue stock awards, including stock options, performance shares, and restricted stock units, to key employees and outside directors. In general, the awards vest over five years, either based on the company’s earnings growth or the passage of time. The related compensation expense for each award is recognized over the appropriate vesting period. The fair value of each share-based payment award is established on the date of grant. For grants of shares and restricted stock units, the fair value is established based on the market price on the date of the grant, discounted for post-vesting holding restrictions. The discounts on outstanding grants vary from 12 percent to 22 percent and are calculated using the Black-Scholes option pricing model-protective put method. Changes in measured stock volatility and interest rates are the primary reason for changes in the discount. For grants of options, we use the Black-Scholes option pricing model to estimate the fair value of share-based payment awards. The determination of the fair value of share-based awards is affected by our stock price and a number of assumptions, including expected volatility, expected term, risk-free interest rate, and dividend yield.

Prior period amounts have been reclassified to conform with the current year presentation. Goodwill is tested at least annually for impairment on November 30, or more frequently if events or changes in circumstances indicate that the asset might be impaired. We first perform a qualitative assessment to determine whether it is more likely than not that the fair value of our reporting units is less than their respective carrying value (“Step Zero Analysis”). If the Step Zero Analysis indicates it is more likely than not that the fair value of our reporting units is less than their respective carrying value, an additional impairment assessment is performed (“Step One Analysis”). Based on our Step Zero Analysis, we determined that the more likely than not criteria had not been met, and therefore a Step One Analysis was not required. No goodwill or intangible asset impairment has been recorded in any period presented.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENT Accounting guidance on fair value measurements for certain financial assets and liabilities requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: • Level 1-Quoted market prices in active markets for identical assets or liabilities. • Level 2-Observable market-based inputs or unobservable inputs that are corroborated by market data. • Level 3-Unobservable inputs reflecting the reporting entity’s own assumptions or external inputs from inactive markets. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement.

SENIOR UNSECURED REVOLVING CREDIT FACILITY We have a senior unsecured revolving credit facility (the "Credit Agreement") with a total availability of $1 billion and a maturity date of October 24, 2023. Borrowings under the Credit Agreement generally bear interest at a variable rate determined by a pricing schedule or the base rate (which is the highest of (a) the administrative agent's prime rate, (b) the federal funds rate plus 0.50 percent, or (c) the sum of one-month LIBOR plus a specified margin). As of December 31, 2019, the variable rate equaled LIBOR plus 1.13 percent. In addition, there is a commitment fee on the average daily undrawn stated amount under each letter of credit issued under the facility ranging from 0.075 percent to 0.200 percent. The recorded amount of borrowings outstanding approximates fair value because of the short maturity period of the debt; therefore, we consider these borrowings to be a Level 2 financial liability. The Credit Agreement contains various restrictions and covenants that require us to maintain certain financial ratios, including a maximum leverage ratio of 3.50 to 1.00. The Credit Agreement also contains customary events of default. If an event of default under the Credit Agreement occurs and is continuing, then the administrative agent may declare any outstanding obligations under the Credit Agreement to be immediately due and payable. In addition, if we become the subject of voluntary or involuntary proceedings under any bankruptcy, insolvency, or similar law, then any outstanding obligations under the Credit Agreement will automatically become immediately due and payable. NOTE PURCHASE AGREEMENT On August 23, 2013, we entered into a Note Purchase Agreement with certain institutional investors (the “Purchasers”). On August 27, 2013, the Purchasers purchased an aggregate principal amount of $500 million of our Senior Notes, Series A, Senior Notes Series B, and Senior Notes Series C, collectively (the “Notes”). Interest on the Notes is payable semi-annually in arrears. The fair value of the Notes approximated $539.3 million at December 31, 2019. We estimate the fair value of the Notes primarily using an expected present value technique, which is based on observable market inputs using interest rates currently available to companies of similar credit standing for similar terms and remaining maturities, and considering our own risk. If the Notes were recorded at fair value, they would be classified as Level 2. The Note Purchase Agreement contains various restrictions and covenants that require us to maintain certain financial ratios, including a maximum leverage ratio of 3.00 to 1.00, a minimum interest coverage ratio of 2.00 to 1.00, and a maximum consolidated priority debt to consolidated total asset ratio of 15 percent. The Note Purchase Agreement provides for customary events of default. The occurrence of an event of default would permit certain Purchasers to declare certain Notes then outstanding to be immediately due and payable. Under the terms of the Note Purchase Agreement, the Notes are redeemable, in whole or in part, at 100 percent of the principal amount being redeemed together with a “make-whole amount” (as defined in the Note Purchase Agreement), and accrued and unpaid interest with respect to each Note. The obligations of the company under the Note Purchase Agreement and the Notes are guaranteed by C.H. Robinson Company, a Delaware corporation and a wholly-owned subsidiary of the company, and by C.H. Robinson Company, Inc., a Minnesota corporation and an indirect wholly-owned subsidiary of the company. U.S. TRADE ACCOUNTS RECEIVABLE SECURITIZATION On April 26, 2017, we entered into a receivables purchase agreement and related transaction documents with The Bank of Tokyo-Mitsubishi UFJ, Ltd., New York Branch and Wells Fargo Bank, N.A. to provide a receivables securitization facility (the “Receivables Securitization Facility”). On December 17, 2018, we entered into an amendment on the Receivables Securitization Facility which changed the lending parties to Wells Fargo Bank, N.A. and Bank of America, N.A. and extended the maturity date from April 26, 2019, to December 17, 2020. The Receivables Securitization Facility is based on the securitization of our U.S. trade accounts receivable and provides funding of up to $250 million. The interest rate on borrowings under the Receivables Securitization Facility is based on 30 day LIBOR plus a margin. There is also a commitment fee we are required to pay on any unused portion of the facility. The Receivables Securitization Facility expires on December 17, 2020, unless extended by the parties and is recorded as a current liability as of December 31, 2019. The recorded amount of borrowings outstanding on the Receivables Securitization Facility approximates fair value because it can be redeemed on short notice and the interest rate floats. We consider these borrowings to be a Level 2 financial liability. The Receivables Securitization Facility contains various customary affirmative and negative covenants, and it also contains customary default and termination provisions which provide for acceleration of amounts owed under the Receivables Securitization Facility upon the occurrence of certain specified events. SENIOR NOTES On April 9, 2018, we issued senior unsecured notes ("Senior Notes") through a public offering. The Senior Notes bear an annual interest rate of 4.20 percent payable semi-annually on April 15 and October 15, until maturity on April 15, 2028. The proceeds from the Senior Notes were utilized to pay down the balance on our Credit Agreement. Taking into effect the amortization of the original issue discount and all underwriting and issuance expenses, the Senior Notes have an effective yield to maturity of approximately 4.39 percent per annum. The fair value of the Senior Notes, excluding debt discounts and issuance costs, approximated $659.9 million as of December 31, 2019, based primarily on the market prices quoted from external sources. The carrying value of the Senior Notes was $592.4 million as of December 31, 2019. If the Senior Notes were measured at fair value in the financial statements, they would be classified as Level 2 in the fair value hierarchy. We may redeem the Senior Notes, in whole or in part, at any time and from time to time prior to their maturity at the applicable redemption prices described in the Senior Notes. Upon the occurrence of a “change of control triggering event” as defined in the Senior Notes (generally, a change of control of us accompanied by a reduction in the credit rating for the Senior Notes), we will generally be required to make an offer to repurchase the Senior Notes from holders at 101 percent of their principal amount plus accrued and unpaid interest to the date of repurchase. The Senior Notes were issued under an indenture that contains covenants imposing certain limitations on our ability to incur liens, enter into sales and leaseback transactions and consolidate, merge or transfer substantial all of our assets and those of our subsidiaries on a consolidated basis. It also provides for customary events of default (subject in certain cases to customary grace and cure periods), which include among other things nonpayment, breach of covenants in the indenture, and certain events of bankruptcy and insolvency. If an event of default occurs and is continuing with respect to the Senior Notes, the trustee or holders of at least 25 percent in principal amount outstanding of the Senior Notes may declare the principal and the accrued and unpaid interest, if any, on all of the outstanding Senior Notes to be due and payable. These covenants and events of default are subject to a number of important qualifications, limitations, and exceptions that are described in the indenture. The indenture does not contain any financial ratios or specified levels of net worth or liquidity to which we must adhere.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESC.H. Robinson Worldwide, Inc. and its 80 percent (or more) owned U.S. subsidiaries file a consolidated federal income tax return. We file unitary or separate state returns based on state filing requirements. With few exceptions, we are no longer subject to audits of U.S. federal, state and local, or non-U.S. income tax returns before 2012. We are currently under an Internal Revenue Service audit for the 2015-2017 tax years. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act made broad and complex changes to the U.S. tax code, including but not limited to, reducing the U.S. federal corporate tax rate from 35 percent to 21 percent and requiring companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries and adding new rules for Global Intangible Low-tax Income (“GILTI”) and Foreign Derived Intangible Income (“FDII”). Although enacted more than two years ago, regulatory guidance on the application of FDII has not been finalized. We have included the tax impact of both GILTI and FDII in our income tax expense for the twelve months ended December 31, 2019, based on our understanding of the rules available at the time of this filing. However, our calculations could be impacted by future regulations as guidance is finalized. We will continue to monitor any new guidance related to FDII and determine any impact it may have on our calculations. In 2019 we removed our assertion, except for regarding the working capital of our largest China subsidiary, that the unremitted earnings of our foreign subsidiaries were permanently reinvested. Following the removal of that assertion, we recorded tax expense of $13.9 million related to foreign withholding taxes paid and accrued during the fourth quarter of 2019. That expense was partially offset by tax benefits of $11.1 million related to excess foreign tax credits, and a tax benefit of $1.8 million related to foreign exchange losses on previously taxed income. If we repatriated all foreign earnings that are still considered to be permanently reinvested, the estimated effect on income taxes payable would be an increase of approximately $3.9 million as of December 31, 2019. Income before provision for income taxes consisted of (in thousands): 2019 2018 2017 Domestic $ 649,742 $ 738,927 $ 638,718 Foreign 92,515 141,346 89,745 Total $ 742,257 $ 880,273 $ 728,463 A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding interest and penalties, is as follows (in thousands): 2019 2018 2017 Unrecognized tax benefits, beginning of period $ 31,515 $ 31,806 $ 12,268 Additions based on tax positions related to the current year 2,212 — 4,014 Additions for tax positions of prior years 2,148 1,662 16,713 Reductions for tax positions of prior years — (263) — Lapse in statute of limitations (1,703) (1,394) (1,189) Settlements (234) (296) — Unrecognized tax benefits, end of the period $ 33,938 $ 31,515 $ 31,806 Income tax expense considers amounts which may be needed to cover exposures for open tax years. We do not expect any material impact related to open tax years; however, actual settlements may differ from amounts accrued. As of December 31, 2019, we had $39.9 million of unrecognized tax benefits and related interest and penalties, all of which would affect our effective tax rate if recognized. We are not aware of any tax positions for which it is reasonably possible that the total amount of unrecognized tax benefit will significantly increase or decrease in the next 12 months. The total liability for unrecognized tax benefits is expected to decrease by approximately $3.1 million in the next 12 months due to lapsing of statutes. We recognize interest and penalties related to uncertain tax positions in the provision for income taxes. During the years ended December 31, 2019, 2018, and 2017, we recognized approximately $1.0 million, $1.0 million, and $0.7 million, respectively, in interest and penalties. We had approximately $6.0 million and $6.5 million for the payment of interest and penalties related to uncertain tax positions accrued within noncurrent income taxes payable as of December 31, 2019 and 2018.

CAPITAL STOCK AND STOCK AWARD PLANS	CAPITAL STOCK AND STOCK AWARD PLANS PREFERRED STOCK. Our Certificate of Incorporation authorizes the issuance of 20,000,000 shares of preferred stock, par value $0.10 per share. There are no shares of preferred stock outstanding. The preferred stock may be issued by resolution of our Board of Directors at any time without any action of the stockholders. The Board of Directors may issue the preferred stock in one or more series and fix the designation and relative powers. These include voting powers, preferences, rights, qualifications, limitations, and restrictions of each series. The issuance of any such series may have an adverse effect on the rights of holders of common stock and may impede the completion of a merger, tender offer, or other takeover attempt. COMMON STOCK. Our Certificate of Incorporation authorizes 480,000,000 shares of common stock, par value $0.10 per share. Subject to the rights of preferred stock which may from time to time be outstanding, holders of common stock are entitled to receive dividends out of funds legally available, when and if declared by the Board of Directors, and to receive their share of the net assets of the company legally available for distribution upon liquidation or dissolution. For each share of common stock held, stockholders are entitled to one vote on each matter to be voted on by the stockholders, including the election of directors. Holders of common stock are not entitled to cumulative voting. The stockholders do not have preemptive rights. All outstanding shares of common stock are fully paid and nonassessable. STOCK AWARD PLANS. Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense as it vests. A summary of our total compensation expense recognized within personnel expenses in our consolidated statements of operations and comprehensive income for stock-based compensation is as follows (in thousands): 2019 2018 2017 Stock options $ 16,073 $ 23,374 $ 10,109 Stock awards 20,170 61,826 29,217 Company expense on ESPP discount 2,840 2,591 2,479 Total stock-based compensation expense $ 39,083 $ 87,791 $ 41,805 On May 9, 2019, our shareholders approved an amendment and restatement of our 2013 Equity Incentive Plan ("the Plan") to increase the number of shares authorized for award by 4,000,000 shares. The Plan allows us to grant certain stock awards, including stock options at fair market value and performance shares and restricted stock units, to our key employees and outside directors. At the time our shareholders approved adding additional shares to the plan, a maximum of 17,041,803 shares are available to be granted under this plan. Approximately 5,300,634 shares were available for stock awards under this plan as of December 31, 2019. Shares subject to awards that expire or are canceled without delivery of shares or that are settled in cash, generally become available again for issuance under the plan. We awarded performance-based stock options to certain key employees during years prior to 2015. These options were subject to certain vesting requirements over a five five The following schedule summarizes stock option activity in the plans. All outstanding unvested options as of December 31, 2019, relate to time-based grants from 2015 through 2019. Options Weighted Aggregate Average Outstanding at December 31, 2018 7,822,514 $ 74.42 $ 85,222 7.2 Grants 151,040 82.46 Exercised (725,685) 65.58 Forfeitures (197,677) 77.87 Outstanding at December 31, 2019 7,050,192 $ 75.40 $ 44,067 6.4 Vested at December 31, 2019 4,507,070 $ 71.17 5.6 Exercisable at December 31, 2019 4,507,070 $ 71.17 5.6 As of December 31, 2019, unrecognized compensation expense related to stock options was $40.4 million. The amount of future expense to be recognized will be based on the passage of time and the employees' continued employment. Additional potential dilutive stock options totaling 3,348,501 for 2019 have been excluded from our diluted net income per share calculations because these securities’ exercise prices were anti-dilutive (e.g., greater than the average market price of our common stock). Information on the intrinsic value of options exercised is as follows (in thousands): 2019 $ 15,862 2018 16,209 2017 6,026 We have awarded stock options to certain key employees that vest primarily based on their continued employment. The value of these awards is established by the market price on the date of the grant, discounted for post-vesting holding restrictions, calculated using the Black-Scholes option pricing model and is being expensed over the vesting period of the award. The following table summarizes these unvested stock option grants as of December 31, 2019: First Vesting Date Last Vesting Date Options Weighted Unvested Options December 31, 2016 December 31, 2020 1,421,432 $ 12.66 280,033 December 31, 2017 December 31, 2021 1,238,090 12.60 484,683 December 31, 2018 December 31, 2022 1,447,294 14.25 855,028 December 31, 2019 December 31, 2023 1,159,662 20.13 923,378 5,266,478 $ 14.73 2,543,122 We granted an additional 1,660,548 options on February 5, 2020. These awards had a weighted average exercise price of $72.74 and a weighted average grant date fair value of $13.88. These awards will vest over a five Determining Fair Value We estimated the fair value of stock options granted using the Black-Scholes option pricing model. We estimate the fair value of restricted shares and units using the Black-Scholes option pricing model-protective put method. A description of significant assumptions used to determine the risk-free interest rate, dividend yield, expected volatility, and expected term are as follows: Risk-Free Interest Rate -The risk-free interest rate was based on the implied yield available on U.S. Treasury zero-coupon issues at the date of grant with a term equal to the expected term. Dividend Yield- The dividend yield assumption is based on our history of dividend payouts. Expected Volatility -Expected volatility was determined based on implied volatility of our traded options and historical volatility of our stock price. Expected Term - Expected term represents the period that our stock-based awards are expected to be outstanding and was determined based on historical experience and anticipated future exercise patterns, giving consideration to the contractual terms of unexercised stock-based awards.

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING On January 1, 2019, we reorganized our enterprise transportation services structure to combine our NAST and Robinson Fresh transportation networks. The newly combined transportation network will be managed by and reported under the NAST reportable segment. We have determined that the remaining Robinson Fresh segment no longer meets the requirements of a reportable segment and will be included in the All Other and Corporate reportable segment. Prior period information has been reclassified to conform with this presentation. Our reportable segments are based on our method of internal reporting, which generally segregates the segments by service line and the primary services they provide to our customers. We identify two reportable segments as follows: • North American Surface Transportation: NAST provides freight transportation services across North America through a network of offices in the United States, Canada, and Mexico. The primary services provided by NAST are truckload, less than truckload ("LTL"), and intermodal. • Global Forwarding: Global Forwarding provides global logistics services through an international network of offices in North America, Asia, Europe, Oceania, and South America and also contracts with independent agents worldwide. The primary services provided by Global Forwarding include ocean freight services, air freight services, and customs brokerage. • All Other and Corporate: All Other and Corporate includes our Robinson Fresh and Managed Services segments, as well as Other Surface Transportation outside of North America and other miscellaneous revenues and unallocated corporate expenses. Robinson Fresh provides sourcing services including the buying, selling, and marketing of fresh fruits, vegetables, and other perishable items. Managed Services provides Transportation Management Services, or Managed TMS ® . Other Surface Transportation revenues are primarily earned by our Europe Surface Transportation segment. Europe Surface Transportation provides services similar to NAST across Europe. The internal reporting of segments is defined, based in part, on the reporting and review process used by our chief operating decision maker ("CODM"), our Chief Executive Officer. The accounting policies of our reporting segments are the same as those described in the summary of significant accounting policies. We do not report our intersegment revenues by reportable segment to our CODM and do not believe they are a meaningful metric for evaluating the performance of our reportable segments. Reportable segment information as of, and for the years ended, December 31, 2019, 2018, and 2017 is as follows (dollars in thousands): NAST Global Forwarding All Other and Corporate Consolidated Twelve Months Ended December 31, 2019 Total Revenues $ 11,283,692 $ 2,327,913 $ 1,697,903 $ 15,309,508 Net Revenues 1,797,369 533,976 254,965 2,586,310 Income (loss) from operations 722,763 80,527 (13,314) 789,976 Depreciation and amortization 24,508 36,720 39,221 100,449 Total assets (1) 2,550,010 1,021,592 1,069,458 4,641,060 Average headcount 7,354 4,766 3,431 15,551 ________________________________ (1) All cash and cash equivalents and certain owned properties are included in All Other and Corporate.

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMERS	REVENUE FROM CONTRACTS WITH CUSTOMERS We adopted Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers , as of January 1, 2018 using the modified retrospective transition method. The standard outlines a five-step model whereby revenue is recognized as performance obligations within a customer contract are satisfied which changed the timing of revenue recognition for our transportation business from at delivery to over the transit period as our performance obligations are completed. The comparative information for the year ended December 31, 2017 has not been restated and continues to be reported under ASC 605, Revenue Recognition . The impact of adoption of ASU 2014-09 on our consolidated statements of operations for the years ended December 31, 2019 and 2018, was as follows (dollars in thousands).

This change resulted in these contracts being recognized at the net amount we charge our customers but had no impact on income from operations. We typically do not receive consideration and amounts are not due from our customer prior to the completion of our performance obligations and as such contract liabilities as of December 31, 2019 and 2018, and revenue recognized in the twelve months ended December 31, 2019 and 2018, resulting from contract liabilities were not significant. Contract assets and accrued expenses - transportation expense fluctuate from period to period primarily based upon shipments in-transit at period and the timing of customer invoicing. A summary of our total revenues disaggregated by major service line and timing of revenue recognition is presented below for each of our reportable segments for the twelve months ended December 31, 2019 and 2018, as follows (dollars in thousands): Twelve Months Ended December 31, 2019 NAST Global Forwarding All Other and Corporate Total Major service lines: Transportation and logistics services (1) $ 11,283,692 $ 2,327,913 $ 710,690 $ 14,322,295 Sourcing (2) — — 987,213 987,213 Total $ 11,283,692 $ 2,327,913 $ 1,697,903 $ 15,309,508 Twelve Months Ended December 31, 2018 NAST Global Forwarding All Other and Corporate Total Major service lines: Transportation and logistics services (1) $ 12,346,757 $ 2,487,744 $ 681,420 $ 15,515,921 Sourcing (2) — — 1,115,251 1,115,251 Total $ 12,346,757 $ 2,487,744 $ 1,796,671 $ 16,631,172 ________________________________ (1) Transportation and logistics services performance obligations are completed over time. (2) Sourcing performance obligations are completed at a point in time. Approximately 92 percent and 91 percent of our total revenues for the twelve months ended December 31, 2019 and 2018, respectively, are attributable to arranging for the transportation of our customers’ freight for which we transfer control and satisfy our performance obligation over the requisite transit period. A days in transit output method is used to measure the progress of our performance as of the reporting date. We determine the transit period based upon the departure date and the delivery date, which may be estimated if delivery has not occurred as of the reporting date. Determining the transit period and how much of it has been completed as of the reporting date may require management to make judgments that affect the timing of revenue recognized. We have determined that revenue recognition over the transit period provides a faithful depiction of the transfer of goods and services to our customer as our obligation is performed over the transit period. The transaction price for our performance obligation under these arrangements is generally fixed and readily determinable upon contract inception and is not contingent upon the occurrence or non-occurrence of another event. Approximately six percent and seven percent of our total revenues for the twelve months ended December 31, 2019 and 2018, respectively, are attributable to buying, selling, and/or marketing of produce including fresh fruits, vegetables, and other value-added perishable items. Total revenues for these transactions are recognized at a point in time upon completion of our performance obligation, which is generally when the produce is received by our customer. The transaction price for our performance obligation under these arrangements is generally fixed and readily determinable upon contract inception and is not contingent upon the occurrence or non-occurrence of another event. Approximately two percent of our total revenues for the twelve months ended December 31, 2019 and 2018, respectively, are attributable to value-added logistics services, such as customs brokerage, fee-based managed services, warehousing services, small parcel, and supply chain consulting and optimization services. Total revenues for these services are recognized over time as we complete our performance obligation. Transaction price is determined and allocated to these performance obligations at their fixed fee or agreed upon rate multiplied by their associated measure of progress, which may be transactional volumes, labor hours, or time elapsed. Practical Expedients - Upon the adoption of ASU 2014-09, we have determined that we qualify for certain practical expedients to facilitate the adoption of the standard. We have elected to expense incremental costs of obtaining customer contracts (i.e., sales commissions) due to the short duration of our arrangements as the amortization period of such amounts is expected to be less than one year. These amounts are included within personnel expenses in our consolidated statements of operations and comprehensive income. In addition, we do not disclose the aggregate amount of transaction price allocated to performance obligations that are unsatisfied as of the end of the period, as our contracts have an expected length of one year or less. Finally, for certain of our performance obligations such as fee-based managed services, supply chain consulting and optimization services, and warehousing services, we have recognized revenue in the amount for which we have the right to invoice our customer as we have determined this amount corresponds directly with the value provided to the customer for our performance completed to date.

LEASES

LEASES	12 Months Ended
	Dec. 31, 2019
Leases [Abstract]
LEASES	LEASES We adopted ASU 2016-02, Leases (Topic 842), as of January 1, 2019. Prior period information was not restated and continues to be presented under ASC 840, Leases . We elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to not reassess existing contracts to determine if they contain a lease and to carry forward their historical lease classification upon transition. In addition, we have made a policy election to not apply the guidance of ASC 842 to leases with a term of 12 months or less as allowed by the standard. These leases are recognized as expense on a straight-line basis over the lease term. Adoption of the new standard resulted in the recording of right-of-use lease assets and lease liabilities of $265.4 million and $273.3 million, respectively, as of January 1, 2019. The adoption of this standard did not materially impact our consolidated statements of operations or consolidated statements of cash flows. We determine if our contractual agreements contain a lease at inception. A lease is identified when a contract allows us the right to control an identified asset for a period of time in exchange for consideration. Our lease agreements consist primarily of operating leases for office space, warehouses, office equipment, and a small number of intermodal containers. We do not have material financing leases. Frequently, we enter into contractual relationships with a wide variety of transportation companies for freight capacity, and utilize those relationships to efficiently and cost-effectively arrange the transport of our customers’ freight. These contracts typically have a term of 12 months or less and do not allow us to direct the use or obtain substantially all of the economic benefits of a specifically identified asset. Accordingly, these agreements are not considered leases. Our operating leases are included on the consolidated balance sheets as right-of-use lease assets and lease liabilities. A right-of-use lease asset represents our right to use an underlying asset over the term of a lease, while a lease liability represents our obligation to make lease payments arising from the lease. Current and noncurrent lease liabilities are recognized at commencement date at the present value of lease payments, including non-lease components, which consist primarily of common area maintenance charges. Right-of-use lease assets are also recognized at commencement date as the total lease liability plus prepaid rents and less any deferred rent liability that existed under ASC 840, Leases, upon transition. As our leases typically do not provide an implicit rate, we use our fully collateralized incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate is influenced by market interest rates, our credit rating, and lease term and as such, may differ for individual leases. Our lease agreements typically do not contain variable lease payments, residual value guarantees, purchase options, or restrictive covenants. Many of our leases include the option to renew for a period of months to several years. The term of our leases may include the option to renew when it is reasonably certain that we will exercise that option although these occurrences are seldom. We have lease agreements with lease components (e.g., payments for rent) and non-lease components (e.g., payments for common area maintenance and parking), which are all accounted for as a single lease component. In February 2020, we entered into a lease for warehouse space in Los Angeles, California which commences in February 2020 and is expected to result in a right-of-use lease asset and lease liability of approximately $38.7 million. There were no other material lease agreements that have not yet commenced that are expected to create significant rights or obligations as of December 31, 2019. Information regarding lease expense, remaining lease term, discount rate, and other select lease information is presented below as of December 31, 2019, and for the twelve months ended December 31, 2019 (dollars in thousands): Lease Costs Twelve Months Ended December 31, 2019 Operating lease expense $ 68,489 Short-term lease expense 11,440 Total lease expense $ 79,929 Other Lease Information Twelve Months Ended December 31, 2019 Operating cash outflows from operating leases $ 66,489 Right-of-use lease assets obtained in exchange for new lease liabilities (1) 101,966 ________________________________ (1) The company obtained approximately $35.5 million of right-of-use lease assets in exchange for new lease liabilities related to a warehouse lease in Australia in the fourth quarter of 2019.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS RECENTLY ADOPTED ACCOUNTING STANDARDS In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . This update requires a lessee to recognize on the balance sheet a liability to make lease payments and a corresponding right-of-use asset. The guidance also requires certain qualitative and quantitative disclosures about the amount, timing, and uncertainty of cash flows arising from leases. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements , which provides another transition method no longer requiring application to previously reported periods. Therefore, prior period balances were not restated. We adopted Topic 842 during 2019 using the modified retrospective approach and recognizing right-of-use assets and lease liabilities of $265.4 million and $273.3 million, respectively, on January 1, 2019. The adoption of this standard did not have a significant impact on our consolidated results of operations or consolidated statements of cash flows. Refer to Note 11, Leases , for further information. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income , which amends existing guidance for reporting comprehensive income to reflect changes resulting from the Tax Act. The amendment provides the option to reclassify stranded tax effects resulting from the Tax Act within accumulated other comprehensive income (AOCI) to retained earnings. This amendment became effective for us on January 1, 2019. The adoption of this standard did not have a material impact on our consolidated financial statements and disclosures. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , and in November 2018 issued a subsequent amendment, ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses . This update significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The update will replace today’s “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. The update will affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope of this amendment that have the contractual right to receive cash. We adopted this standard effective January 1, 2020. Prior period balances will not be restated. The adoption of this standard will impact our accounting policy for the allowance for doubtful accounts, which is a significant accounting policy, but the impact of adoption is not expected to have a material impact to our consolidated financial position, results of operations, or cash flows.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION. C.H. Robinson Worldwide, Inc. and our subsidiaries (“the company,” “we,” “us,” or “our”) are a global provider of transportation services and logistics solutions through a network of offices operating in North America, Europe, Asia, Oceania, and South America. The consolidated financial statements include the accounts of C.H. Robinson Worldwide, Inc. and our majority owned and controlled subsidiaries. Our minority interests in subsidiaries are not significant. All intercompany transactions and balances have been eliminated in the consolidated financial statements.
USE OF ESTIMATES	USE OF ESTIMATES. The preparation of financial statements, in conformity with accounting principles generally accepted in the United States, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates have been prepared on the basis of the most current and best information, and our actual results could differ materially from those estimates.
REVENUE RECOGNITION	REVENUE RECOGNITION. At contract inception, we assess the goods and services promised in our contracts with customers and identify our performance obligations to provide distinct goods and services to our customers. We have determined that the following distinct goods and services represent our primary performance obligations. Transportation and Logistics Services - As a third party logistics provider, our primary performance obligation under our customer contracts is to utilize our relationships with a wide variety of transportation companies to efficiently and cost-effectively transport our customers’ freight. Revenue is recognized for these performance obligations as they are satisfied over the contract term, which generally represents the transit period. The transit period can vary based upon the method of transport, generally a number of days for over the road, rail, and air transportation, or several weeks in the case of an ocean shipment. Determining the transit period and how much of it has been completed as of the reporting date may require management to make judgments that affect the timing of revenue recognized. When the customers’ freight reaches its intended destination our performance obligation is complete. Pricing for our services is generally a fixed amount and is typically due within 30 days upon completion of our performance obligation. We also provide certain value-added logistics services, such as customs brokerage, fee-based managed services, warehousing services, small parcel, and supply chain consulting and optimization services. These services may include one or more performance obligations which are generally satisfied over the service period as we perform our obligations. The service period may be a very short duration, in the case of customs brokerage and small parcel, or it may be longer in the case of warehousing, managed services and supply chain consulting and optimization services. Pricing for our services is established in the customer contract and is dependent upon the specific needs of the customer but may be agreed upon at a fixed fee per transaction, labor hour, or service period. Payment is typically due within 30 days upon completion of our performance obligation. Sourcing Services - We contract with grocery retailers, restaurants, foodservice distributors, and produce wholesalers to provide sourcing services under the trade name Robinson Fresh. Our primary service obligation under these contracts is the buying, selling, and/or marketing of produce including fresh fruits, vegetables, and other value-added perishable items. Revenue is recognized when our performance obligations under these contracts is satisfied at a point in time, generally when the produce is received by our customer. Pricing under these contracts is generally a fixed amount and is typically due within 30 days upon completion of our performance obligation. In many cases, as additional performance obligations, we contract to arrange logistics and transportation of the products we buy, sell, and/or market. These performance obligations are satisfied over the contract term consistent with our other transportation and logistics services. The contract period is typically less than one year. Pricing for our services is generally a fixed amount and is typically due within 30 days upon completion of our performance obligation. Total revenues represent the total dollar value of revenue recognized from contracts with customers for the goods and services we provide. Substantially all of our revenue is attributable to contracts with our customers. Our net revenues are our total revenues less purchased transportation and related services, including contracted motor carrier, rail, ocean, air, and other costs, and the purchase price and services related to the products we source. Most transactions in our transportation and sourcing businesses are recorded at the gross amount we charge our customers for the service we provide and goods we sell. In these transactions, we are primarily responsible for fulfilling the promise to provide the specified good or service to our customer and we have discretion in establishing the price for the specified good or service. Additionally, in our sourcing business, in some cases we take inventory risk before the specified good has been transferred to our customer. Customs brokerage, managed
CONTRACT ASSETS	CONTRACT ASSETS. Contract assets represent amounts for which we have the right to consideration for the services we have provided while a shipment is still in-transit but for which we have not yet completed our performance obligation or have not yet invoiced our customer. Upon completion of our performance obligations, which can vary in duration based upon the method of transport, and billing our customer these amounts become classified within accounts receivable and are then typically due within 30 days.
ACCRUED TRANSPORTATION EXPENSE	ACCRUED TRANSPORTATION EXPENSE. Accrued transportation expense represents amounts we owe to vendors, primarily transportation providers, for the services they have provided while a shipment is still in-transit as of the reporting date.
ALLOWANCE FOR DOUBTFUL ACCOUNTS	ALLOWANCE FOR DOUBTFUL ACCOUNTS. Accounts receivable are reduced by an allowance for amounts that may become uncollectible in the future. We continuously monitor payments from our customers and maintain a provision for uncollectible accounts based upon our customer aging trends, historical loss experience, and any specific customer collection issues that we have identified.
FOREIGN CURRENCY	FOREIGN CURRENCY. Most balance sheet accounts of foreign subsidiaries are remeasured and translated at the current exchange rate as of the end of the year. Translation adjustments are recorded in other comprehensive (loss) income. Statement of operations items are translated at the average exchange rate during the year.
CASH AND CASH EQUIVALENTS	CASH AND CASH EQUIVALENTS. Cash and cash equivalents consist primarily of bank deposits and highly liquid investments with an original maturity of three months or less from the time of purchase.
PREPAID EXPENSES AND OTHER	PREPAID EXPENSES AND OTHER. Prepaid expenses and other include such items as software maintenance contracts, insurance premiums, other prepaid operating expenses, and inventories, consisting primarily of produce and related products held for resale.
RIGHT-OF-USE LEASE ASSETS AND LEASE LIABILITIES	RIGHT-OF-USE LEASE ASSETS. Right-of-use lease assets are recognized upon lease commencement and represent our right to use an underlying asset for the lease term. LEASE LIABILITIES. Lease liabilities are recognized at commencement date and represent our obligation to make the lease payments arising from a lease, measured on a discounted basis.
PROPERTY AND EQUIPMENT	PROPERTY AND EQUIPMENT. Property and equipment are recorded at cost. Maintenance and repair expenditures are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated lives of the assets. Amortization of leasehold improvements is computed over the shorter of the lease term or the estimated useful lives of the improvements.
GOODWILL	GOODWILL. Goodwill represents the excess of the cost of acquired businesses over the net of the fair value of identifiable tangible net assets and identifiable intangible assets purchased and liabilities assumed. Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis (November 30 for us) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value.
OTHER INTANGIBLE ASSETS	OTHER INTANGIBLE ASSETS. Other intangible assets include definite-lived customer lists, non-competition agreements, and indefinite-lived trademarks. The definite-lived intangible assets are being amortized using the straight-line method over their estimated lives, ranging from five
OTHER ASSETS	OTHER ASSETS. Other assets consist primarily of purchased and internally developed software, and the investments related to our nonqualified deferred compensation plan. We amortize software using the straight-line method over three years.
INCOME TAXES	INCOME TAXES. Income taxes are accounted for using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted rates. Annual tax provisions include amounts considered sufficient to pay assessments that may result from examination of prior year tax returns; however, the amount ultimately paid upon resolution of issues raised may differ from the amounts accrued. The financial statement benefits of an uncertain income tax position are recognized when more likely than not, based on the technical merits, the position will be sustained upon examination. Unrecognized tax benefits are, more likely than not, owed to a taxing authority, and the amount of the contingency can be reasonably estimated. Uncertain income tax positions are included in “Accrued income taxes” or “Noncurrent income taxes payable” in the consolidated balance sheets.
COMPREHENSIVE INCOME (LOSS)	COMPREHENSIVE INCOME (LOSS). Comprehensive income (loss) consists primarily of foreign currency translation adjustments. It is presented on our consolidated statements of operations and comprehensive income gross of related income tax effects.
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION. We issue stock awards, including stock options, performance shares, and restricted stock units, to key employees and outside directors. In general, the awards vest over five years, either based on the company’s earnings growth or the passage of time. The related compensation expense for each award is recognized over the appropriate vesting period. The fair value of each share-based payment award is established on the date of grant. For grants of shares and restricted stock units, the fair value is established based on the market price on the date of the grant, discounted for post-vesting holding restrictions. The discounts on outstanding grants vary from 12 percent to 22 percent and are calculated using the Black-Scholes option pricing model-protective put method. Changes in measured stock volatility and interest rates are the primary reason for changes in the discount. For grants of options, we use the Black-Scholes option pricing model to estimate the fair value of share-based payment awards. The determination of the fair value of share-based awards is affected by our stock price and a number of assumptions, including expected volatility, expected term, risk-free interest rate, and dividend yield.
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENT Accounting guidance on fair value measurements for certain financial assets and liabilities requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: • Level 1-Quoted market prices in active markets for identical assets or liabilities. • Level 2-Observable market-based inputs or unobservable inputs that are corroborated by market data. • Level 3-Unobservable inputs reflecting the reporting entity’s own assumptions or external inputs from inactive markets.
RECENTLY ISSUED ACCOUNTING PRNOUNCEMENTS	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS RECENTLY ADOPTED ACCOUNTING STANDARDS In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . This update requires a lessee to recognize on the balance sheet a liability to make lease payments and a corresponding right-of-use asset. The guidance also requires certain qualitative and quantitative disclosures about the amount, timing, and uncertainty of cash flows arising from leases. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements , which provides another transition method no longer requiring application to previously reported periods. Therefore, prior period balances were not restated. We adopted Topic 842 during 2019 using the modified retrospective approach and recognizing right-of-use assets and lease liabilities of $265.4 million and $273.3 million, respectively, on January 1, 2019. The adoption of this standard did not have a significant impact on our consolidated results of operations or consolidated statements of cash flows. Refer to Note 11, Leases , for further information. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income , which amends existing guidance for reporting comprehensive income to reflect changes resulting from the Tax Act. The amendment provides the option to reclassify stranded tax effects resulting from the Tax Act within accumulated other comprehensive income (AOCI) to retained earnings. This amendment became effective for us on January 1, 2019. The adoption of this standard did not have a material impact on our consolidated financial statements and disclosures. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , and in November 2018 issued a subsequent amendment, ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses . This update significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The update will replace today’s “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. The update will affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope of this amendment that have the contractual right to receive cash. We adopted this standard effective January 1, 2020. Prior period balances will not be restated. The adoption of this standard will impact our accounting policy for the allowance for doubtful accounts, which is a significant accounting policy, but the impact of adoption is not expected to have a material impact to our consolidated financial position, results of operations, or cash flows.
