Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure	1. BASIS OF PRESENTATION AND USE OF ESTIMATES Basis of Presentation In this report, “Bio-Rad,” “we,” “us,” “the Company” and “our” refer to Bio-Rad Laboratories, Inc. and its subsidiaries. The accompanying unaudited condensed consolidated financial statements of Bio-Rad have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and reflect all adjustments which are, in the opinion of management, necessary to fairly state the results of the interim periods presented. All such adjustments are of a normal recurring nature. Results for the interim period are not necessarily indicative of the results for the entire year. The condensed consolidated balance sheet at December 31, 2017 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. The condensed consolidated financial statements should be read in conjunction with the notes to the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2017 . We evaluate subsequent events and the evidence they provide about conditions existing at the date of the balance sheet as well as conditions that arose after the balance sheet date but through the date the financial statements are issued. The effects of conditions that existed at the balance sheet date are recognized in the financial statements. Events and conditions arising after the balance sheet date but before the financial statements are issued are evaluated to determine if disclosure is required to keep the financial statements from being misleading. To the extent such events and conditions exist, disclosures are made regarding the nature of events and the estimated financial effects of those events and conditions. Use of Estimates The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting periods. Bio-Rad bases its estimates on historical experience and on various other market-specific and other relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates. Revenue Recognition On January 1, 2018, we adopted Accounting Standards Codification ("ASC") 606, "Revenue from Contracts with Customers," using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported under prior revenue guidance ASC 605, "Revenue Recognition." We recorded a net reduction to opening retained earnings of $0.1 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606 with the impact primarily related to a customer loyalty program in the United States for which the resulting non-cash consideration is treated as variable consideration under the new revenue recognition accounting standard. The impact to revenue as a result of applying ASC 606 as compared to ASC 605 for the nine months ended September 30, 2018 was not significant. We recognize revenue from operations through the sale of products, services, and rental of instruments. Revenue from contracts with customers is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We enter into contracts that can include various combinations of products and services, which are generally accounted for as distinct performance obligations. Revenue is recognized net of any taxes collected from customers (sales tax, value added tax, etc.), which are subsequently remitted to government authorities. Our contracts from customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment and may or may not impact the timing of revenue recognition. Revenue associated with equipment that requires factory installation is not recorded until installation is complete and customer acceptance, if required, has occurred. Certain equipment requires installation due to the fact that the instruments are being operated in a clinical/laboratory environment, and the installation services could result in modification of the equipment in order to ensure that the instruments are working according to specifications of the customer which are subject to validation tests upon completion of the installation. In these arrangements, which require factory installation, the delivery of the equipment and the installation are separate performance obligations. We will recognize the transaction price allocated to the equipment only upon customer acceptance, as the transfer of control has occurred in relation to the equipment at that point in time as the customer has the ability to direct the use of and obtain substantially all of the remaining benefits from the asset. The transaction price allocated to the installation services is also recognized upon completion of the services because without the completion of the installation services and related customer acceptance the customer cannot receive any of the benefits of the service. At the time revenue is recognized, a provision is recognized for estimated product returns as this right is considered variable consideration. Accordingly, when product revenues are recognized, the transaction price is reduced to the estimated amount that we expect to receive in exchange for transferring control for those products. Service revenues on extended warranty contracts are recognized ratably over the life of the service agreement as a stand-ready performance obligation. For arrangements that include a combination of products and services, transaction prices are allocated to performance obligations based on stand-alone selling prices. The method used to determine the stand-alone selling prices for service revenues is based on the observable prices when the services have been sold separately. In those instances where the timing of revenue recognition differs from the timing of invoicing, we have determined that our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simple and predictable methods of purchasing our products and services, not to either provide or receive financing to or from our customers. We record contract liabilities when cash payments are received or due in advance of our performance. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less and for contracts in which we recognize revenue at the amount to which we have the right to invoice for services performed. Our payment terms vary by the type and location of our customer, and the products and services offered. The term between invoicing and when payment is due is not significant. Reagent Rental Agreements Reagent rental agreements are a diagnostic industry sales method that provides use of an instrument and consumables (reagents) to a customer on a per test basis. These agreements may also include maintenance of the underlying instruments retained at customer locations as well as initial training. We concluded that the use of the instrument and related maintenance services (collectively known as “lease elements”) are not within the guidance of ASC 606 but rather ASC 840 Leases. Accordingly, we first allocate the transaction price between the lease elements and the non-lease elements based on relative standalone selling prices. The determination of the transaction price requires judgment and requires consideration of any fixed/minimum payments as well as estimates of variable consideration. After determining what portion of the transaction price should be allocated to the lease elements, any fixed consideration would be considered the minimum lease payment to be amortized straight line over the lease term and any variable consideration would be contingent rent to be recognized monthly as earned, which coincides with the transfer of control of the non-lease elements. For the portion of the transaction price allocated to the non-lease elements, which are principally the reagents, the related revenue will be recognized at a point in time when control transfers. Generally, the terms of the arrangements result in the transfer of control upon either (i) when the consumables are delivered or (ii) when the consumables are consumed by the customer. Revenue allocated to the lease elements of these reagent rental arrangements represent approximately 5% of total revenue and are included as part of the Net sales in our Condensed Consolidated Statements of Income. Contract costs: As a practical expedient, we expense as incurred costs to obtain contracts as the amortization period would have been one year or less. These costs, recorded within Selling, general and administrative expense, include our internal sales force compensation programs and certain partner sales incentive programs, as we have determined that annual compensation is commensurate with annual selling activities. Disaggregation of Revenue: The following table presents our revenues disaggregated by geographic region based primarily on the location of the use of the product or service (in millions, unaudited): Three Months Ended Nine Months Ended September 30, September 30, 2018 2017 2018 2017 Europe $ 182.7 $ 190.3 $ 579.5 $ 539.3 Pacific Rim 110.3 105.7 341.7 307.9 United States 218.3 203.3 649.8 593.2 Other (primarily Canada and Latin America) 33.8 34.8 101.6 98.5 Total Net sales $ 545.1 $ 534.1 $ 1,672.6 $ 1,538.9 The disaggregation of our revenue by industry segment sources is presented in our Segment Information footnote (see Note 10). Deferred revenues represent mostly unrecognized fees billed or collected for extended service arrangements. Deferred revenues are recognized as (or when) we perform under the contract, which is generally recognized ratably over the term of the service contract. A majority of our deferred revenue balance is classified as current with an expected length of one year or less. The increase in our total deferred revenue balance from $36.7 million at December 31, 2017 to $39.3 million at September 30, 2018 is primarily driven by $30.8 million , net, of cash payments received or due in advance of satisfying our performance obligations, offset by $28.2 million of revenue recognized that were included in our deferred revenue balance as of December 31, 2017 . We warrant certain equipment against defects in design, materials and workmanship, generally for a period of one year. Upon revenue recognition of that equipment, we establish, as part of Cost of goods sold, a provision for the expected costs of such warranty based on historical experience, specific warranty terms and customer feedback. A review is performed on a quarterly basis to assess the adequacy of our warranty accrual. Components of the warranty accrual, included in Other current liabilities and Other long-term liabilities in the Condensed Consolidated Balance Sheets, were as follows (in millions): January 1, 2018 $ 18.7 Provision for warranty 25.8 Actual warranty costs (27.7 ) September 30, 2018 $ 16.8 Recent Accounting Pronouncements Adopted In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. ("ASU") 2018-03, "Technical Corrections and Improvements to Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2018-03 amends certain items in ASU 2016-01 (see below) such as equity securities without a readily determinable fair value. ASU 2018-03 clarifies that an entity that uses the measurement alternative for equity securities without readily determinable fair values can change its measurement approach to fair value and once made the election is irrevocable. If an entity measures equity securities without readily determinable fair values at fair value, it must record a cumulative-effect adjustment to Retained earnings as of the beginning of the fiscal year in which the guidance is adopted. We adopted ASU 2018-03 on January 1, 2018 and made an irrevocable election to account for our investment of the ordinary shares of Sartorius AG at fair value (see ASU 2016-01 below). In January 2016, the FASB issued ASU 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities." Amendments under ASU 2016-01, among other items, require that all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) will generally be measured at fair value through earnings. Changes in fair value for equity securities will no longer be reported in other comprehensive income. For equity investments without readily determinable fair values, the cost method is also eliminated. We adopted ASU 2016-01 on January 1, 2018 and record equity investments without readily determinable fair values at cost, less impairment, and plus or minus subsequent adjustments for observable price changes and were valued at $0.6 million as of September 30, 2018 . Changes in the basis of these equity investments are reported in current earnings. For equity securities that are affected by ASU 2016-01 and ASU 2018-03, see Note 2 to the condensed consolidated financial statements, which primarily consists of our investment in Sartorius AG. The impact of the adoption of ASU 2016-01 and ASU 2018-03 on January 1, 2018 was through a cumulative-effect adjustment of $864.5 million to Total stockholders' equity by increasing Retained earnings of $1,543.7 million and decreasing Accumulated other comprehensive income of $679.2 million , including increasing Deferred income taxes by $232.9 million and an increase in Other investments of $1,097.4 million in our Condensed Consolidated Balance Sheet. As a result of ASU 2016-01 and ASU 2018-03 for the three and nine months ended September 30, 2018 , we recorded $318.0 million and $1,420.3 million , respectively, for the Change in fair market value of equity securities in the Condensed Consolidated Statement of Income that resulted in a deferred tax expense for the three and nine months ended September 30, 2018 of $70.0 million and $313.7 million , respectively. In March 2017, the FASB issued ASU 2017-07, "Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which changed how we present the net periodic benefit cost of our defined benefit pension and/or other postretirement plans. We adopted ASU 2017-07 on January 1, 2018 and applied the practical expedient to estimate amounts for comparative purposes utilizing the information disclosed in Note 12 to the consolidated financial statements in our Form 10-K for the year ended December 31, 2017. The interest costs are recorded in Interest expense, and the other costs are recorded in Other (income) expense, net in the Condensed Consolidated Statements of Income. For the third quarter of 2017 for interest costs and other costs, we reclassified $0.076 million , $0.538 million , and $0.036 million from Costs of goods sold (COGS), Selling, general and administrative expense (SG&A) and Research and development expense (R&D), respectively, to Interest expense of $0.275 million and Other (income) expense, net of $0.375 million . For the first nine months of 2017 for interest costs and other costs, we reclassified $0.228 million , $1.614 million , and $0.108 million from COGS, SG&A and R&D, respectively, to Interest expense of $0.825 million and Other (income) expense, net of $1.125 million . In November 2016, the FASB issued ASU 2016-18, "Restricted Cash," which required us to cease to present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. We adopted ASU 2016-18 on January 1, 2018 and updated the Condensed Consolidated Statements of Cash Flows to incorporate restricted cash included in Other current assets and Other assets of $1.1 million as of September 30, 2018 and $1.1 million as of September 30, 2017 . In October 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory," which required immediate recognition of income tax consequences of intercompany asset transfers, other than inventory transfers. We adopted ASU 2016-16 on January 1, 2018 on a modified retrospective basis through a cumulative-effect adjustment by decreasing Retained earnings by $17.6 million , and decreasing Prepaid taxes by $22.8 million and increasing Deferred tax assets by $5.2 million that are both recorded in Other assets in our Condensed Consolidated Balance Sheet. In August 2016, FASB issued ASU 2016-15, "Classification of Certain Cash Receipts and Cash Payments" and adopted it on January 1, 2018, which did not have an impact to our statement of cash flows presentation. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASC 606"), an updated standard on revenue recognition. The new standard provides enhancements to the quality and consistency of how revenue is reported under the principle that revenue should be recognized in an amount that reflects the consideration to which we expect to be entitled in exchange for the transfer of promised goods or services. We adopted ASC 606 as of January 1, 2018 using the cumulative effect transition method as more fully described above under the caption “Revenue Recognition.” Recent Accounting Pronouncements to be Adopted In August 2018, the FASB issued ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." ASU 2018-15 amends the definition of a hosting arrangement and requires a customer in a hosting arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. The internal-use software guidance states that only qualifying costs incurred during the application development stage can be capitalized. ASU 2018-15 is effective for fiscal years ending after December 15, 2019. Early adoption is permitted and entities have the option to apply the guidance prospectively to all implementation costs incurred after the date of adoption or retrospectively. We are currently evaluating the effect ASU 2018-15 will have on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." ASU 2018-14 eliminates and adds certain disclosures for defined benefit plans. ASU 2018-14 is effective for fiscal years ending after December 15, 2020 using a retrospective approach, with early adoption permitted. We are currently evaluating the disclosures and the timing of adoption but do not expect ASU 2018-14 to have a material impact to our disclosures for defined benefit plans. In August 2018, the FASB issued ASU 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." ASU 2018-13 eliminates, adds and modifies certain disclosures for fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. Early adoption is permitted in interim periods, including periods for which financial statements have not yet been issued. We do not expect ASU 2018-13 to have a material impact to our fair value disclosures and we currently do not plan to early adopt. In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments." ASU 2016-13 will replace the current incurred loss approach with an expected loss model for instruments measured at amortized cost and require entities to record allowances for available-for-sale debt securities rather than reduce the carrying amount under the current other-than-temporary impairment model. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted for all entities for annual periods beginning after December 15, 2018, and interim periods therein. We are currently evaluating the effect ASU 2016-13 will have on our consolidated financial statements.

Fair Value Measurements	FAIR VALUE MEASUREMENTS We determine the fair value of an asset or liability based on the assumptions that market participants would use in pricing the asset or liability in an orderly transaction between market participants at the measurement date. The identification of market participant assumptions provides a basis for determining what inputs are to be used for pricing each asset or liability. A fair value hierarchy has been established which gives precedence to fair value measurements calculated using observable inputs over those using unobservable inputs. This hierarchy prioritizes the inputs into three broad levels as follows: • Level 1: Quoted prices in active markets for identical instruments • Level 2: Other significant observable inputs (including quoted prices in active markets for similar instruments) • Level 3: Significant unobservable inputs (including assumptions in determining the fair value of certain investments) Financial assets and liabilities carried at fair value and measured on a recurring basis as of September 30, 2018 are classified in the hierarchy as follows (in millions): Level 1 Level 2 Level 3 Total Financial Assets Carried at Fair Value: Cash equivalents: Commercial paper $ — $ 70.7 $ — $ 70.7 Asset backed — 0.1 — 0.1 Time deposits 24.0 10.0 — 34.0 Money market funds 35.0 — — 35.0 Total cash equivalents (a) 59.0 80.8 — 139.8 Restricted investment 5.6 — — 5.6 Equity securities (b) 3,502.7 — — 3,502.7 Available-for-sale investments: Corporate debt securities — 223.5 — 223.5 U.S. government sponsored agencies — 76.1 — 76.1 Foreign government obligations — 3.3 — 3.3 Municipal obligations — 15.6 — 15.6 Asset-backed securities — 61.0 — 61.0 Total available-for-sale investments (c) — 379.5 — 379.5 Forward foreign exchange contracts (d) — 1.5 — 1.5 Total financial assets carried at fair value $ 3,567.3 $ 461.8 $ — $ 4,029.1 Financial Liabilities Carried at Fair Value: Forward foreign exchange contracts (e) $ — $ 1.5 $ — $ 1.5 Contingent consideration (f) — — 8.1 8.1 Total financial liabilities carried at fair value $ — $ 1.5 $ 8.1 $ 9.6 As of first quarter 2018, our equity securities are no longer reported as Available-for-sale investments due to the implementation of ASU 2016-01. Changes in fair value of equity securities are now reported on the Condensed Consolidated Statements of Income rather than Other Comprehensive Income (see Note 1). Financial assets and liabilities carried at fair value and measured on a recurring basis as of December 31, 2017 are classified in the hierarchy as follows (in millions): Level 1 Level 2 Level 3 Total Financial Assets Carried at Fair Value: Cash equivalents: Commercial paper $ — $ 36.0 $ — $ 36.0 Time deposits 43.7 10.0 — 53.7 U.S. government sponsored agencies — 11.2 — 11.2 Money market funds 3.4 — — 3.4 Total cash equivalents (a) 47.1 57.2 — 104.3 Restricted investment 5.6 — — 5.6 Available-for-sale investments: Corporate debt securities — 185.7 — 185.7 U.S. government sponsored agencies — 67.6 — 67.6 Foreign government obligations — 3.4 — 3.4 Brokered certificates of deposit — 0.7 — 0.7 Municipal obligations — 15.0 — 15.0 Marketable equity securities 973.4 — — 973.4 Asset-backed securities — 55.6 — 55.6 Total available-for-sale investments (c) 973.4 328.0 — 1,301.4 Forward foreign exchange contracts (d) — 0.5 — 0.5 Total financial assets carried at fair value $ 1,026.1 $ 385.7 $ — $ 1,411.8 Financial Liabilities Carried at Fair Value: Forward foreign exchange contracts (e) $ — $ 1.6 $ — $ 1.6 Contingent consideration (f) — — 16.7 16.7 Total financial liabilities carried at fair value $ — $ 1.6 $ 16.7 $ 18.3 (a) Cash equivalents are included in Cash and cash equivalents in the Condensed Consolidated Balance Sheets. (b) Equity securities are included in the following accounts in the Condensed Consolidated Balance Sheets (in millions): September 30, 2018 Short-term investments $ 46.7 Other investments 3,456.0 Total $ 3,502.7 The unrealized gains on our equity securities still held as of September 30, 2018 are $1,420.3 million and are primarily due to our investment in Sartorius AG and is recorded in our Condensed Consolidated Statements of Income due to the adoption of ASU 2016-01 (see Note 1). (c) Available-for-sale investments are included in the following accounts in the Condensed Consolidated Balance Sheets (in millions): September 30, 2018 December 31, 2017 Short-term investments $ 379.3 $ 371.2 Other investments 0.2 930.2 Total $ 379.5 $ 1,301.4 In accordance with our adoption of ASU 2016-01 January 1, 2018, our investment in Sartorius AG preferred shares, which was reported within marketable equity securities as Available-for-sale as of December 31, 2017 , is now reported as an Equity security as of September 30, 2018 (see Note 1 and footnote (b) above). (d) Forward foreign exchange contracts in an asset position are included in Other current assets in the Condensed Consolidated Balance Sheets. (e) Forward foreign exchange contracts in a liability position are included in Other current liabilities in the Condensed Consolidated Balance Sheets. (f) Contingent consideration liability is included in the following accounts in the Condensed Consolidated Balance Sheets (in millions): September 30, 2018 December 31, 2017 Other current liabilities $ 3.1 $ 2.7 Other long-term liabilities 5.0 14.0 Total $ 8.1 $ 16.7 During the first quarter of 2016, we recognized a contingent consideration liability upon our acquisition of a high performance analytical flow cytometer platform from Propel. At the acquisition date, the amount of contingent consideration was determined based on a probability-weighted income approach related to the achievement of sales milestones, ranging from 39% to 20% for the calendar years 2018 through 2020 . The sales milestones could potentially range from $0 to an unlimited amount. In the first and third quarters of 2018, we paid $1.3 million and $0.8 million , respectively, per the purchase agreement. Since 2016 we have decreased the cumulative valuation of the sales milestones by $12.5 million . The contingent consideration was accrued at its estimated fair value of $8.1 million as of September 30, 2018 . The following table provides a reconciliation of the Level 3 analytical flow cytometer platform contingent consideration liabilities measured at estimated fair value (in millions): January 1, 2018 $ 16.7 Payment of sales milestone (2.1 ) Decrease in estimated fair value of contingent consideration included in Selling, general and administrative expense (6.5 ) September 30, 2018 $ 8.1 The following table provides quantitative information about Level 3 inputs for fair value measurement of our analytical flow cytometer platform contingent consideration liability as of September 30, 2018 . Significant increases or decreases in these inputs in isolation could result in a significantly lower or higher fair value measurement. Valuation Technique Unobservable Input Analytical flow cytometer platform Probability-weighted income approach Sales milestones: Discount rate 11.3 % Cost of debt 4.9 % To estimate the fair value of Level 2 debt securities as of September 30, 2018 and December 31, 2017 , our primary pricing provider uses Securities Evaluations as the primary pricing source. Our pricing process allows us to select a hierarchy of pricing sources for securities held. If Securities Evaluations does not price a Level 2 security that we hold, then the pricing provider will utilize our custodian supplied pricing as the secondary pricing source. For commercial paper as of September 30, 2018 and December 31, 2017 , pricing is determined by a straight-line calculation, starting with the purchase price on the date of purchase and increasing to par at maturity. Interest bearing certificates of deposit and commercial paper are priced at par. In the event that an additional lot of the same commercial paper issue has been purchased within the same account, then the price of all holdings of that issue in that account will be the price of the most recent lot purchased. Our pricing provider performs daily reasonableness testing of the Securities Evaluations prices. Price changes of 5% or greater are investigated and resolved. In addition, we perform a quarterly comparison of the Securities Evaluations prices to custodian reported prices. Price differences outside a tolerable variance of approximately 1% are investigated and resolved. Available-for-sale investments consist of the following (in millions): September 30, 2018 Amortized Cost Unrealized Gains Unrealized Losses Estimated Fair Value Short-term investments: Corporate debt securities $ 224.7 $ 0.1 $ (1.3 ) $ 223.5 Municipal obligations 15.7 — (0.1 ) 15.6 Asset-backed securities 61.1 — (0.3 ) 60.8 U.S. government sponsored agencies 77.6 — (1.5 ) 76.1 Foreign government obligations 3.3 — — 3.3 382.4 0.1 (3.2 ) 379.3 Long-term investments: Asset-backed securities 0.2 — — 0.2 0.2 — — 0.2 Total $ 382.6 $ 0.1 $ (3.2 ) $ 379.5 The following is a summary of the amortized cost and estimated fair value of our debt securities at September 30, 2018 by contractual maturity date (in millions): Amortized Cost Estimated Fair Value Mature in less than one year $ 170.3 $ 170.0 Mature in one to five years 164.9 163.3 Mature in more than five years 47.4 46.2 Total $ 382.6 $ 379.5 Available-for-sale investments consist of the following (in millions): December 31, 2017 Amortized Cost Unrealized Gains Unrealized Losses Estimated Fair Value Short-term investments: Corporate debt securities $ 185.9 $ 0.3 $ (0.5 ) $ 185.7 Brokered certificates of deposit 0.7 — — 0.7 Municipal obligations 15.1 — (0.1 ) 15.0 Asset-backed securities 55.6 — (0.2 ) 55.4 U.S. government sponsored agencies 68.3 — (0.7 ) 67.6 Foreign government obligations 3.4 — — 3.4 Marketable equity securities 34.4 9.0 — 43.4 363.4 9.3 (1.5 ) 371.2 Long-term investments: Marketable equity securities 54.5 875.5 — 930.0 Asset-backed securities 0.2 — — 0.2 54.7 875.5 — 930.2 Total $ 418.1 $ 884.8 $ (1.5 ) $ 1,301.4 The following is a summary of investments with gross unrealized losses and the associated fair value (in millions): September 30, 2018 December 31, 2017 Fair value of investments in a loss position 12 months or more $ 70.7 $ 43.9 Fair value of investments in a loss position less than 12 months $ 242.8 $ 168.7 Gross unrealized losses for investments in a loss position 12 months or more $ 1.5 $ 0.7 Gross unrealized losses for investments in a loss position less than 12 months $ 1.7 $ 0.8 The unrealized losses on these securities are due to a number of factors, including changes in interest rates, changes in economic conditions and changes in market outlook for various industries, among others. Because Bio-Rad has the ability and intent to hold these investments with unrealized losses until a recovery of fair value, or for a reasonable period of time sufficient for a forecasted recovery of fair value, which may be maturity, we do not consider these investments to be other-than-temporarily impaired at September 30, 2018 or at December 31, 2017 . As part of distributing our products, we regularly enter into intercompany transactions. We enter into forward foreign exchange contracts to manage foreign exchange risk of future movements in foreign exchange rates that affect foreign currency denominated intercompany receivables and payables. We do not use derivative financial instruments for speculative or trading purposes. We do not seek hedge accounting treatment for these contracts. As a result, these contracts, generally with maturity dates of 90 days or less and denominated primarily in currencies of industrial countries, are recorded at their fair value at each balance sheet date. The notional principal amounts provide one measure of the transaction volume outstanding as of September 30, 2018 and do not represent the amount of Bio-Rad's exposure to loss. The estimated fair value of these contracts was derived using the spot rates from Reuters on the last business day of the quarter and the points provided by counterparties. The resulting gains or losses offset exchange gains or losses on the related receivables and payables, both of which are included in Foreign currency exchange losses, net in the Condensed Consolidated Statements of Income. The following is a summary of our forward foreign exchange contracts (in millions): September 30, 2018 Contracts maturing in October through December 2018 to sell foreign currency: Notional value $ 52.4 Unrealized loss $ 0.2 Contracts maturing in October through December 2018 to purchase foreign currency: Notional value $ 288.0 Unrealized loss $ — The estimated fair value of financial instruments that are not recognized at fair value in the Condensed Consolidated Balance Sheets and are included in Other investments, are presented in the table below. Fair value has been determined using significant observable inputs, including quoted prices in active markets for similar instruments. Estimates are not necessarily indicative of the amounts that could be realized in a current market exchange as considerable judgment is required in interpreting market data used to develop estimates of fair value. The use of different market assumptions or estimation techniques could have a material effect on the estimated fair value. Other investments include financial instruments, the majority of which have fair value based on similar, actively traded stock adjusted for various discounts, including a discount for marketability. Long-term debt, excluding leases and current maturities, has an estimated fair value based on quoted market prices for the same or similar issues. The estimated fair value of the financial instruments discussed above and the level of the fair value hierarchy within which the fair value measurement is categorized are as follows (in millions): September 30, 2018 December 31, 2017 Carrying Amount Estimated Fair Value Fair Value Hierarchy Level Carrying Amount Estimated Fair Value Fair Value Hierarchy Level Other investments — — $ 91.8 $ 1,249.4 2 Total long-term debt, excluding leases and current maturities $ 423.6 $ 436.4 2 $ 423.1 $ 449.8 2 We own shares of ordinary voting stock of Sartorius AG (Sartorius), of Goettingen, Germany, a process technology supplier to the biotechnology, pharmaceutical, chemical and food and beverage industries. We own over 37% of the outstanding voting shares (excluding treasury shares) of Sartorius as of September 30, 2018 . The Sartorius family trust and Sartorius family members hold a controlling interest of the outstanding voting shares.

The sale yielded net cash proceeds of $422.6 million at an effective rate of 4.946% . The 4.875% Notes pay a fixed rate of interest of 4.875% per year. We have the option to redeem any or all of the 4.875% Notes at any time at a redemption price of 100% of the principal amount (plus a specified make-whole premium as defined in the indenture governing the 4.875% Notes) and accrued and unpaid interest thereon to the redemption date. Our obligations under the 4.875% Notes are not secured and rank equal in right of payment with all of our existing and future unsubordinated indebtedness. Certain covenants apply at each year end to the 4.875% Notes including limitations on the following: liens, sale and leaseback transactions, mergers, consolidations or sales of assets and other covenants. There are no restrictive covenants relating to total indebtedness, interest coverage, stock repurchases, recapitalizations, dividends and distributions to shareholders or current ratios. Credit Agreement In June 2014, Bio-Rad entered into a $200.0 million unsecured Credit Agreement. Borrowings under the Credit Agreement are on a revolving basis and can be used to make permitted acquisitions, for working capital and for other general corporate purposes. We had no outstanding borrowings under the Credit Agreement as of September 30, 2018 or December 31, 2017 , however $0.5 million was utilized for domestic standby letters of credit that reduced our borrowing availability as of September 30, 2018 . The Credit Agreement matures in June 2019 . If we had borrowed against our Credit Agreement, the borrowing rate would have been 3.523% at September 30, 2018 . The Credit Agreement requires Bio-Rad to comply with certain financial ratios and covenants, among other things. These ratios and covenants include a leverage ratio test and an interest coverage test, as well as restrictions on our ability to declare or pay dividends, incur debt, guarantee debt, enter into transactions with affiliates, merge or consolidate, sell assets, make investments and create liens. We were in compliance with all of these ratios and covenants as of September 30, 2018

Earnings Per Share [Abstract]
Earnings Per Share	. EARNINGS PER SHARE Basic earnings per share is computed by dividing net income attributable to Bio-Rad by the weighted average number of common shares outstanding for that period. Diluted earnings per share takes into account the effect of dilutive instruments, such as stock options and restricted stock, and uses the average share price for the period in determining the number of potential common shares that are to be added to the weighted average number of shares outstanding. Potential common shares are excluded from the diluted earnings per share calculation if the effect of including such securities would be anti-dilutive. The weighted average number of common shares outstanding used to calculate basic and diluted earnings per share, and the anti-dilutive shares that are excluded from the diluted earnings per share calculation are as follows (in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2018 2017 2018 2017 Basic weighted average shares outstanding 29,863 29,660 29,822 29,618 Effect of potentially dilutive stock options and restricted stock awards 429 392 412 376 Diluted weighted average common shares 30,292 30,052 30,234 29,994 Anti-dilutive shares 64 12 35 22

Income Tax Disclosure [Abstract]
Income Taxes	. INCOME TAXES Our effective income tax rate was 23% and 28% for the three months ended September 30, 2018 and 2017 , respectively. Our effective income tax rate was 23% and 24% for the nine months ended September 30, 2018 and 2017 , respectively. The effective tax rate for the three and nine months ended September 30, 2018 was driven primarily by the $318.0 million and $1.4 billion gain on equity investments, respectively, taxable at the U.S. federal and state rate of approximately 22% . The effective tax rate for the three and nine months ended September 30, 2017 was lower than the U.S. federal statutory rate of 35% due to the impact of discrete items. In accordance with SAB 118, our accounting for the following elements of the Tax Act was incomplete at December 31, 2017. However, we were able to make reasonable estimates of certain effects and, therefore, recorded provisional estimates as follows: • Our deferred tax assets and liabilities were remeasured at the enacted tax rate that will apply when these temporary differences are expected to be realized or settled. • The Tax Act imposes a Transition Tax payable over eight years. The Transition Tax is assessed on the U.S. shareholders’ share of certain foreign corporations’ accumulated untaxed foreign earnings. Earnings in the form of cash and cash equivalents are taxed at a rate of 15.5% and all other earnings are taxed at a rate of 8.0%. In December 2017, we recorded a provisional income tax expense of $55 million for Transition Tax. • For certain other elements of the Tax Act, our accounting was incomplete, and we were not able to make reasonable estimates of those effects. For example, we did not make a determination as to our accounting policy with respect to the new Global Intangible Low-Taxed Income ("GILTI"). During the quarter ended September 30, 2018 , the Internal Revenue Service and U.S. Treasury issued proposed regulations related to Transition Tax and GILTI. While these regulations are not considered authoritative and are subject to change in the regulatory review process, they contain a number of rules that may impact us including but not limited to tax basis adjustment and anti-avoidance rules. We will continue our analysis of these provisional amounts including collecting necessary data during the measurement period, and record any adjustments to our provisional estimates in the fourth quarter. For the period ended September 30, 2018 , we did not record adjustments to our provisional amounts. As regulatory guidance and interpretations become available, further adjustments may be necessary in future periods. We assess our ability to realize our net deferred tax assets on a quarterly basis and establish a valuation allowance if it is more-likely-than-not that some portion of the deferred tax assets will not be realized in the foreseeable future. Due to the weight of negative evidence, including our history of losses in certain jurisdictions, we believe that it is more-likely-than-not that certain foreign deferred tax assets will not be realized as of September 30, 2018 . Accordingly, we have maintained a valuation allowance on such deferred tax assets. Our income tax returns are routinely audited by U.S. federal, state and foreign tax authorities. We are currently under examination by many of these tax authorities. There are differing interpretations of tax laws and regulations, and as a result, significant disputes may arise with these tax authorities involving issues of the timing and amount of deductions and allocations of income among various tax jurisdictions. We evaluate our exposures associated with our tax filing positions on a quarterly basis. We record liabilities for unrecognized tax benefits related to uncertain tax positions. We do not believe any currently pending uncertain tax positions will have a material adverse effect on our condensed consolidated financial statements, although an adverse resolution of one or more of these uncertain tax positions in any period may have a material impact on the results of operations for that period. As of September 30, 2018 , based on the expected outcome of certain examinations or as a result of the expiration of statute of limitations for certain jurisdictions, we believe that within the next 12 months it is reasonably possible that our previously unrecognized tax benefits could decrease by up to $3 million

Segment results are presented in the same manner as we present our operations internally to make operating decisions and assess performance. Net corporate operating, interest and other expense for segment results consists of receipts and expenditures that are not the primary responsibility of segment operating management and therefore are not allocated to the segments for performance assessment by our chief operating decision maker. Interest expense is charged to segments based on the carrying amount of inventory and receivables employed by that segment. For the three and nine months ended September 30, 2018 compared to the same periods in 2017 , our Life Science segment had increased sales and gross profit. In addition, the Life Science segment gross margin included a $10.0 million one-time expense associated with the RainDance acquisition in the first quarter of 2017.

Loss Contingency, Information about Litigation Matters [Abstract]
Legal Proceedings.	11. LEGAL PROCEEDINGS On May 27, 2015, our former general counsel, Sanford S. Wadler, filed a lawsuit in the U.S. District Court, Northern District of California, against us and four of our then current directors and one former director. The plaintiff’s suit alleged whistleblower retaliation in violation of the Sarbanes-Oxley Act and the Dodd-Frank Act for raising FCPA-related concerns. Mr. Wadler also alleged wrongful termination in violation of public policy, non-payment of wages and waiting time penalties in violation of the California Labor Code. The plaintiff sought back pay, compensatory damages for lost wages, earnings, retirement benefits and other employee benefits, compensation for mental pain and anguish and emotional distress, waiting time penalties, punitive damages, litigation costs (including attorneys’ fees) and reinstatement of employment. On July 28, 2015 we filed a motion to dismiss the plaintiff's complaint and specifically requested dismissal of the claims alleged against us under the Dodd-Frank Act and California Labor Code 1102.5 and the claims against the directors under the Sarbanes-Oxley Act and the Dodd-Frank Act. On October 23, 2015, the District Court granted our motion with respect to the alleged violations of the Sarbanes-Oxley Act against all the director defendants except Norman Schwartz with prejudice. The Court denied our motion to dismiss the claims under the Dodd-Frank Act as against both us and the director defendants. The trial commenced on January 17, 2017 and concluded on February 6, 2017. Mr. Wadler was awarded $10.92 million , plus prejudgment interest of $141,608 , post-judgment interest, and Mr. Wadler’s litigation costs, expert witness fees, and reasonable attorneys’ fees as approved by the Court. We have provided for the judgment, interest and Mr. Wadler's litigation costs. On June 6, 2017 we filed a notice of appeal with the United States Court of Appeals for the Ninth Circuit. Oral arguments are scheduled for November 14, 2018.

Restructuring Costs [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	12. RESTRUCTURING COSTS Restructuring Costs for European Reorganization In May, 2016, we announced that we would take certain actions in our Europe geographic region designed to better align expenses to our revenue and gross margin profile and position us for improved operating performance. These actions, aligned with the evolution of our organization structure and coordinated with the implementation of our global single instance enterprise resource planning ("ERP") platform, are expected to be incurred through 2019. From May 2016 to September 30, 2018 , total expenses were $13.0 million . The liability of $2.0 million as of September 30, 2018 was recorded in Accrued payroll and employee benefits in the Condensed Consolidated Balance Sheets. The following table summarizes the activity of our European reorganization restructuring reserves for severance (in millions): Life Science Clinical Diagnostics Total Balances as of January 1, 2018: $ 2.2 $ 4.1 $ 6.3 Cash payments (1.5 ) (2.7 ) (4.2 ) Foreign currency translation gains — (0.1 ) (0.1 ) Balances as of September 30, 2018: $ 0.7 $ 1.3 $ 2.0 Restructuring Costs for Termination of a Diagnostics Research and Development Project and a Facility Closure In December 2017, we announced the termination of a diagnostics research and development project in Europe. From December 2017 to September 30, 2018 , total expenses were $19.9 million . We recorded $(0.6) million and $(1.2) million of adjustments in restructuring charges related to severance and employee benefits, and exit costs for the three and nine months ended September 30, 2018 , respectively. The adjustments were due to a decrease in severance accrual as a result of a reduction in the number of employees being terminated than originally estimated, and a decrease in exit costs as a result of actual legal settlement being lower than the estimate. In June 2018, we announced the closure of a manufacturing facility in Germany. As a result, we recorded $1.3 million of expense in restructuring charges related to severance and employee benefits for the three months ended June 30, 2018. No additional expenses or adjustments were recorded in the three months ended September 30, 2018. Restructuring charges for the termination of a diagnostics research and development project and the facility closure are both included in our Clinical Diagnostics segment's results of operations. The respective amounts recorded for the three and nine months ended September 30, 2018 were reflected in Cost of goods sold of $0 million and $1.3 million , and in Research and development expense of $(0.5) million and $(1.2) million in the Condensed Consolidated Statements of Income. The liability of $7.2 million as of September 30, 2018 for the termination of a diagnostics research and development project and the facility closure was recorded in Accrued payroll and employee benefits in the Condensed Consolidated Balance Sheets. The following table summarizes the activity for the termination of the diagnostics research and development project and the facility closure restructuring reserves for severance and exit costs (in millions): Balances as of January 1, 2018: $ 14.1 Charged to expense 1.3 Adjustment to expense (1.2 ) Cash payments (6.7 ) Foreign currency translation gains (0.3 ) Balances as of September 30, 2018: $ 7.2

Organization, Consolidation and Presentation of Financial Statements [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements Adopted In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. ("ASU") 2018-03, "Technical Corrections and Improvements to Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2018-03 amends certain items in ASU 2016-01 (see below) such as equity securities without a readily determinable fair value. ASU 2018-03 clarifies that an entity that uses the measurement alternative for equity securities without readily determinable fair values can change its measurement approach to fair value and once made the election is irrevocable. If an entity measures equity securities without readily determinable fair values at fair value, it must record a cumulative-effect adjustment to Retained earnings as of the beginning of the fiscal year in which the guidance is adopted. We adopted ASU 2018-03 on January 1, 2018 and made an irrevocable election to account for our investment of the ordinary shares of Sartorius AG at fair value (see ASU 2016-01 below). In January 2016, the FASB issued ASU 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities." Amendments under ASU 2016-01, among other items, require that all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) will generally be measured at fair value through earnings. Changes in fair value for equity securities will no longer be reported in other comprehensive income. For equity investments without readily determinable fair values, the cost method is also eliminated. We adopted ASU 2016-01 on January 1, 2018 and record equity investments without readily determinable fair values at cost, less impairment, and plus or minus subsequent adjustments for observable price changes and were valued at $0.6 million as of September 30, 2018 . Changes in the basis of these equity investments are reported in current earnings. For equity securities that are affected by ASU 2016-01 and ASU 2018-03, see Note 2 to the condensed consolidated financial statements, which primarily consists of our investment in Sartorius AG. The impact of the adoption of ASU 2016-01 and ASU 2018-03 on January 1, 2018 was through a cumulative-effect adjustment of $864.5 million to Total stockholders' equity by increasing Retained earnings of $1,543.7 million and decreasing Accumulated other comprehensive income of $679.2 million , including increasing Deferred income taxes by $232.9 million and an increase in Other investments of $1,097.4 million in our Condensed Consolidated Balance Sheet. As a result of ASU 2016-01 and ASU 2018-03 for the three and nine months ended September 30, 2018 , we recorded $318.0 million and $1,420.3 million , respectively, for the Change in fair market value of equity securities in the Condensed Consolidated Statement of Income that resulted in a deferred tax expense for the three and nine months ended September 30, 2018 of $70.0 million and $313.7 million , respectively. In March 2017, the FASB issued ASU 2017-07, "Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," which changed how we present the net periodic benefit cost of our defined benefit pension and/or other postretirement plans. We adopted ASU 2017-07 on January 1, 2018 and applied the practical expedient to estimate amounts for comparative purposes utilizing the information disclosed in Note 12 to the consolidated financial statements in our Form 10-K for the year ended December 31, 2017. The interest costs are recorded in Interest expense, and the other costs are recorded in Other (income) expense, net in the Condensed Consolidated Statements of Income. For the third quarter of 2017 for interest costs and other costs, we reclassified $0.076 million , $0.538 million , and $0.036 million from Costs of goods sold (COGS), Selling, general and administrative expense (SG&A) and Research and development expense (R&D), respectively, to Interest expense of $0.275 million and Other (income) expense, net of $0.375 million . For the first nine months of 2017 for interest costs and other costs, we reclassified $0.228 million , $1.614 million , and $0.108 million from COGS, SG&A and R&D, respectively, to Interest expense of $0.825 million and Other (income) expense, net of $1.125 million . In November 2016, the FASB issued ASU 2016-18, "Restricted Cash," which required us to cease to present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. We adopted ASU 2016-18 on January 1, 2018 and updated the Condensed Consolidated Statements of Cash Flows to incorporate restricted cash included in Other current assets and Other assets of $1.1 million as of September 30, 2018 and $1.1 million as of September 30, 2017 . In October 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory," which required immediate recognition of income tax consequences of intercompany asset transfers, other than inventory transfers. We adopted ASU 2016-16 on January 1, 2018 on a modified retrospective basis through a cumulative-effect adjustment by decreasing Retained earnings by $17.6 million , and decreasing Prepaid taxes by $22.8 million and increasing Deferred tax assets by $5.2 million that are both recorded in Other assets in our Condensed Consolidated Balance Sheet. In August 2016, FASB issued ASU 2016-15, "Classification of Certain Cash Receipts and Cash Payments" and adopted it on January 1, 2018, which did not have an impact to our statement of cash flows presentation. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASC 606"), an updated standard on revenue recognition. The new standard provides enhancements to the quality and consistency of how revenue is reported under the principle that revenue should be recognized in an amount that reflects the consideration to which we expect to be entitled in exchange for the transfer of promised goods or services. We adopted ASC 606 as of January 1, 2018 using the cumulative effect transition method as more fully described above under the caption “Revenue Recognition.” Recent Accounting Pronouncements to be Adopted In August 2018, the FASB issued ASU 2018-15, "Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." ASU 2018-15 amends the definition of a hosting arrangement and requires a customer in a hosting arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. The internal-use software guidance states that only qualifying costs incurred during the application development stage can be capitalized. ASU 2018-15 is effective for fiscal years ending after December 15, 2019. Early adoption is permitted and entities have the option to apply the guidance prospectively to all implementation costs incurred after the date of adoption or retrospectively. We are currently evaluating the effect ASU 2018-15 will have on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." ASU 2018-14 eliminates and adds certain disclosures for defined benefit plans. ASU 2018-14 is effective for fiscal years ending after December 15, 2020 using a retrospective approach, with early adoption permitted. We are currently evaluating the disclosures and the timing of adoption but do not expect ASU 2018-14 to have a material impact to our disclosures for defined benefit plans. In August 2018, the FASB issued ASU 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." ASU 2018-13 eliminates, adds and modifies certain disclosures for fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. Early adoption is permitted in interim periods, including periods for which financial statements have not yet been issued. We do not expect ASU 2018-13 to have a material impact to our fair value disclosures and we currently do not plan to early adopt. In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments." ASU 2016-13 will replace the current incurred loss approach with an expected loss model for instruments measured at amortized cost and require entities to record allowances for available-for-sale debt securities rather than reduce the carrying amount under the current other-than-temporary impairment model. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted for all entities for annual periods beginning after December 15, 2018, and interim periods therein. We are currently evaluating the effect ASU 2016-13 will have on our consolidated financial statements.
Revenue from Contract with Customer [Policy Text Block]	Revenue Recognition On January 1, 2018, we adopted Accounting Standards Codification ("ASC") 606, "Revenue from Contracts with Customers," using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported under prior revenue guidance ASC 605, "Revenue Recognition." We recorded a net reduction to opening retained earnings of $0.1 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606 with the impact primarily related to a customer loyalty program in the United States for which the resulting non-cash consideration is treated as variable consideration under the new revenue recognition accounting standard. The impact to revenue as a result of applying ASC 606 as compared to ASC 605 for the nine months ended September 30, 2018 was not significant. We recognize revenue from operations through the sale of products, services, and rental of instruments. Revenue from contracts with customers is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We enter into contracts that can include various combinations of products and services, which are generally accounted for as distinct performance obligations. Revenue is recognized net of any taxes collected from customers (sales tax, value added tax, etc.), which are subsequently remitted to government authorities. Our contracts from customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment and may or may not impact the timing of revenue recognition. Revenue associated with equipment that requires factory installation is not recorded until installation is complete and customer acceptance, if required, has occurred. Certain equipment requires installation due to the fact that the instruments are being operated in a clinical/laboratory environment, and the installation services could result in modification of the equipment in order to ensure that the instruments are working according to specifications of the customer which are subject to validation tests upon completion of the installation. In these arrangements, which require factory installation, the delivery of the equipment and the installation are separate performance obligations. We will recognize the transaction price allocated to the equipment only upon customer acceptance, as the transfer of control has occurred in relation to the equipment at that point in time as the customer has the ability to direct the use of and obtain substantially all of the remaining benefits from the asset. The transaction price allocated to the installation services is also recognized upon completion of the services because without the completion of the installation services and related customer acceptance the customer cannot receive any of the benefits of the service. At the time revenue is recognized, a provision is recognized for estimated product returns as this right is considered variable consideration. Accordingly, when product revenues are recognized, the transaction price is reduced to the estimated amount that we expect to receive in exchange for transferring control for those products. Service revenues on extended warranty contracts are recognized ratably over the life of the service agreement as a stand-ready performance obligation. For arrangements that include a combination of products and services, transaction prices are allocated to performance obligations based on stand-alone selling prices. The method used to determine the stand-alone selling prices for service revenues is based on the observable prices when the services have been sold separately. In those instances where the timing of revenue recognition differs from the timing of invoicing, we have determined that our contracts generally do not include a significant financing component. The primary purpose of our invoicing terms is to provide customers with simple and predictable methods of purchasing our products and services, not to either provide or receive financing to or from our customers. We record contract liabilities when cash payments are received or due in advance of our performance. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less and for contracts in which we recognize revenue at the amount to which we have the right to invoice for services performed. Our payment terms vary by the type and location of our customer, and the products and services offered. The term between invoicing and when payment is due is not significant. Reagent Rental Agreements Reagent rental agreements are a diagnostic industry sales method that provides use of an instrument and consumables (reagents) to a customer on a per test basis. These agreements may also include maintenance of the underlying instruments retained at customer locations as well as initial training. We concluded that the use of the instrument and related maintenance services (collectively known as “lease elements”) are not within the guidance of ASC 606 but rather ASC 840 Leases. Accordingly, we first allocate the transaction price between the lease elements and the non-lease elements based on relative standalone selling prices. The determination of the transaction price requires judgment and requires consideration of any fixed/minimum payments as well as estimates of variable consideration. After determining what portion of the transaction price should be allocated to the lease elements, any fixed consideration would be considered the minimum lease payment to be amortized straight line over the lease term and any variable consideration would be contingent rent to be recognized monthly as earned, which coincides with the transfer of control of the non-lease elements. For the portion of the transaction price allocated to the non-lease elements, which are principally the reagents, the related revenue will be recognized at a point in time when control transfers. Generally, the terms of the arrangements result in the transfer of control upon either (i) when the consumables are delivered or (ii) when the consumables are consumed by the customer. Revenue allocated to the lease elements of these reagent rental arrangements represent approximately 5% of total revenue and are included as part of the Net sales in our Condensed Consolidated Statements of Income. Contract costs: As a practical expedient, we expense as incurred costs to obtain contracts as the amortization period would have been one year or less. These costs, recorded within Selling, general and administrative expense, include our internal sales force compensation programs and certain partner sales incentive programs, as we have determined that annual compensation is commensurate with annual selling activities. Disaggregation of Revenue: The following table presents our revenues disaggregated by geographic region based primarily on the location of the use of the product or service (in millions, unaudited): Three Months Ended Nine Months Ended September 30, September 30, 2018 2017 2018 2017 Europe $ 182.7 $ 190.3 $ 579.5 $ 539.3 Pacific Rim 110.3 105.7 341.7 307.9 United States 218.3 203.3 649.8 593.2 Other (primarily Canada and Latin America) 33.8 34.8 101.6 98.5 Total Net sales $ 545.1 $ 534.1 $ 1,672.6 $ 1,538.9 The disaggregation of our revenue by industry segment sources is presented in our Segment Information footnote (see Note 10). Deferred revenues represent mostly unrecognized fees billed or collected for extended service arrangements. Deferred revenues are recognized as (or when) we perform under the contract, which is generally recognized ratably over the term of the service contract. A majority of our deferred revenue balance is classified as current with an expected length of one year or less. The increase in our total deferred revenue balance from $36.7 million at December 31, 2017 to $39.3 million at September 30, 2018 is primarily driven by $30.8 million , net, of cash payments received or due in advance of satisfying our performance obligations, offset by $28.2 million of revenue recognized that were included in our deferred revenue balance as of December 31, 2017 . We warrant certain equipment against defects in design, materials and workmanship, generally for a period of one year. Upon revenue recognition of that equipment, we establish, as part of Cost of goods sold, a provision for the expected costs of such warranty based on historical experience, specific warranty terms and customer feedback. A review is performed on a quarterly basis to assess the adequacy of our warranty accrual. Components of the warranty accrual, included in Other current liabilities and Other long-term liabilities in the Condensed Consolidated Balance Sheets, were as follows (in millions): January 1, 2018 $ 18.7 Provision for warranty 25.8 Actual warranty costs (27.7 ) September 30, 2018 $ 16.8
