Organization, Consolidation and Presentation of Financial Statements [Abstract]

Lessee, Leases [Policy Text Block]

Leases

We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in our condensed consolidated balance sheet as of March 31, 2019. Finance leases are included in property, plant and equipment, other current liabilities, and other long-term liabilities in our condensed consolidated balance sheet as of March 31, 2019.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Where we act as lessee, we elected not to separate lease and non-lease components and are more fully described in Note 14, Leases.

Where we act as lessor in our reagent rental arrangements, we allocate the consideration in the contract to the separate lease components and non-lease components. After allocation, the amount of variable payments allocated to lease components will be recognized as income under the lease accounting standard ASC 842, while the amount of variable payments allocated to non-lease components will be recognized as income in accordance with ASC 606. Such reagent rental arrangements are more fully described above under the caption "Reagent Rental Agreements."

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncements and Securities and Exchange Commission ("SEC") Rule 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. We prospectively adopted ASU 2018-15 effective January 1, 2019. During the first quarter of 2019, we capitalized $0.7 million of implementation costs for cloud computing arrangements, net of accumulated amortization, primarily for business analytics software, and is recorded in Other current assets and Other assets in the Condensed Consolidated Balance Sheet.

In August 2018, the SEC issued Final Rule Release No. 33-10532, "Disclosure Update and Simplification" that extends to interim periods the annual disclosure requirement of presenting the changes in stockholder' equity, which was effective in the first quarter of 2019.

In February 2016, the FASB issued ASU 2016-02, "Leases," and related accounting standard updates, which requires, among other items, lease accounting to recognize most leases as assets and liabilities on the balance sheet. Qualitative and quantitative disclosures are enhanced to better understand the amount, timing and uncertainty of cash flows arising from leases. We adopted ASU 2016-02 on a modified retrospective basis effective January 1, 2019 with practical expedients, and did not restate comparative prior periods. Where we act as a lessee, the adoption of the standard resulted in material additions to the balance sheet for right-of-use assets and the associated liabilities, see Note 14, Leases. The practical expedients include, among other items, for leases that existed prior January 1, 2019, to not reassess whether any contracts are or contain embedded leases, reassessing the classification of existing leases, and reassessing whether previously capitalized initial direct costs qualify for capitalization. Where we act as a lessee, we also elected not to separate lease and non-lease components. Where we act as a lessor in reagent rental arrangements, there was an insignificant impact to our condensed consolidated financial statements, which is more fully described above under the caption "Reagent Rental Agreements."

Recent Accounting Pronouncements to be Adopted

In November 2018, the FASB issued ASU 2018-18, "Clarifying the Interaction between Topic 808 and Topic 606." Topic 808 is Collaborative Arrangements, and Topic 606 is Revenue from Contracts with Customers. ASU 2018-18 clarifies that certain transactions between collaborative partners should be accounted for as revenue under ASC 606 when the collaborative partner is a customer. We currently do not have any customers that are collaborative partners or anticipate any in the near future. ASU 2018-18 will be effective January 1, 2020.

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. We are currently evaluating the disclosures 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. We do not expect ASU 2018-13 to have a material impact to our fair value disclosures.

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. 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 that were not completed as of January 1, 2018.  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.

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 initially determine if a reagent rental arrangement contains a lease at lease commencement. Where we have determined that such an arrangement contains a lease, we next must ascertain its lease classification for purposes of applying appropriate accounting treatment as an operating, sales-type or direct financing lease. In addition, for purposes of determining the lease term used in performing the lease classification test, we include the noncancellable period of the lease together with those periods covered by the option to extend the lease if the customer is reasonably certain to exercise that option, the periods covered by an option to terminate the lease if the customer is reasonably certain not to exercise that option, and the periods covered by the option to extend (or not to terminate) the lease in which exercise of the option is controlled by the company. While most of our reagent rental arrangements contain either the option for a lessee to extend and/or cancel, the period in which the contract is enforceable is a very short period and therefore the lease term has been limited to the non-cancellable period. Furthermore, it has historically been very rare for these arrangements to contain an option for the lessee to purchase the underlying asset.

As discussed further below under the captions “Leases” and “Recent Accounting Pronouncements Adopted,” as well as in Note 14, Leases, we adopted ASC 842, “Leases,” on a modified retrospective basis effective January 1, 2019 with practical expedients, and did not restate comparative prior periods. We concluded that the use of the instrument (referred to as “lease elements”) is not within the guidance of ASC 606 but rather ASC 842. 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 consideration of any fixed/minimum payments as well as estimates of variable consideration. After allocation, the amount of variable payments allocated to lease components will be recognized as income under ASC 842, while the amount of variable payments allocated to non-lease components will be recognized as income in accordance with ASC 606.

Upon our adoption of ASC 842 in 2019, the maintenance services, along with the reagents, are now allocated to the non-lease elements and will be recognized as income in accordance with ASC 606. This change is in alignment with the requirements of ASC 842, and has resulted in a decrease in the amount of rental income that is included in our total revenue. Generally, the terms of the arrangements result in the transfer of control on reagents upon either (i) when the consumables are delivered or (ii) when the consumables are consumed by the customer.

Historically, our reagent rental arrangements have been predominantly comprised of variable lease payments, as very few of such arrangements contain any fixed/minimum lease payments. As a result, our lease income is heavily variable in nature with only relatively insignificant amounts of lease income comprised of fixed or stated minimum lease payments. Further, our reagent rental arrangements are predominantly classified as operating leases, with only very insignificant lease income associated with sales-type leases. Hence, our reported lease income is primarily variable in nature and is recognized over time as the reagents are consumed by the customer or delivered.

Revenue allocated to the lease elements of these reagent rental arrangements represents approximately 3% and 5% of total revenue in the first quarter of 2019 compared to the first quarter of 2018, respectively, and is included as part of 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
	March 31,
	2019		2018
Europe	$	185.9	$	199.6
Pacific Rim	106.4		109.4
United States	226.1		209.9
Other (primarily Canada and Latin America)	35.6		32.6
Total Net sales	$	554.0	$	551.5

The disaggregation of our revenue by industry segment sources is presented in our Segment Information footnote (see Note 11).

Deferred revenues represent mostly unrecognized fees billed or collected for extended service arrangements. Deferred revenues are generally recognized ratably over the term of the service contract as our performance extends over the life of the arrangement. 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 $37.3 million at December 31, 2018 to $41.1 million at March 31, 2019 is primarily driven by $15.2 million, net, of cash payments received or due in advance of satisfying our performance obligations, partially offset by $11.4 million of revenue recognized that were included in our deferred revenue balance as of December 31, 2018.

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):

December 31, 2018	$	10.1
Provision for warranty	1.4
Actual warranty costs	(2.2		)
March 31, 2019	$	9.3
