Revenue Recognition

Revenue Recognition	9 Months Ended
	Sep. 30, 2019
Revenue Recognition Disclosure [Text Block]	2. Revenue Recognition Substantially all of the Company’s sales are from contracts with customers for the purchase of its products. Contracts and customer purchase orders are used to determine the existence of a sales contract. Shipping documents are used to verify shipment. For substantially all of its products, the Company transfers control of products to the customer at the point in time when title and risk are passed to the customer, which generally occurs upon shipment of the product. Each unit sold is considered an independent, unbundled performance obligation. The Company’s sales arrangements do not include other performance obligations that are material in the context of the contract. The nature, timing and amount of revenue for a respective performance obligation are consistent for each customer. The Company measures the sales transaction price based upon the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. Sales and value added taxes are excluded from the measurement of transaction price. The Company’s payment terms for the majority of its customers are 30 to 90 days from shipment. Additionally, certain customers in China pay the Company prior to the shipment of products resulting in a customer deposits liability of $43.7 million and $47.0 million at September 30, 2019 and December 31, 2018, respectively. The Company assesses collectability of customer receivables based on the creditworthiness of a customer as determined by credit checks and analysis, as well as the customer’s payment history. The Company’s allowance for doubtful accounts was $6.2 million and $6.4 million at September 30, 2019 and December 31, 2018, respectively . Rebates and incentives are based on pricing agreements and are tied to sales volume. The amount of revenue is reduced for variable consideration related to customer rebates which are calculated using expected values and are based on program specific factors such as expected rebate percentages based on expected volumes. In situations where the customer has the right to return eligible products, the Company reduces revenue for its estimates of expected product returns, which are primarily based on an analysis of historical experience. Changes in such accruals may be required if actual sales volume differs from estimated sales volume or if future returns differ from historical experience. Shipping and handling costs billed to customers are included in net sales and the related costs are included in cost of products sold and are activities performed to fulfill the promise to transfer products. Disaggregation of Net Sales The Company is comprised of two reporting segments: North America and Rest of World. The Rest of World segment is primarily comprised of China, Europe and India. Both segments manufacture and market comprehensive lines of residential and commercial gas and electric water heaters, boilers, tanks, and water treatment products. Both segments primarily manufacture and market in their respective regions of the world. The Rest of World segment also manufactures and markets in-home As each segment manufactures and markets products in its respective region of the world, the Company has determined that geography is the primary factor in reporting its sales. The Company further disaggregates its North America segment sales by major product line as each of North America’s major product lines is sold through distinct distribution channels and these product lines may be impacted differently by certain economic factors. Within the Rest of World segment, particularly in China and India, the Company’s major customers purchase across the Company’s product lines, utilizing the same distribution channel regardless of product type. In addition, the impact of economic factors is unlikely to be differentiated by product line in the Rest of World segment. The North America segment major product lines are defined as the following: Water heaters Boilers Water treatment products point-of-entry on-the-go point-of-use The following table disaggregates the Company’s net sales by segment. As described above, the Company’s North America segment sales are further disaggregated by major product line. In addition, the Company’s Rest of World segment sales are disaggregated by China and all other Rest of World.

Acquisitions	3. Acquisitions On April 8, 2019, the Company acquired 100 percent of the shares of Water-Right, Inc. and its affiliated entities (Water-Right), a Wisconsin-based water treatment company. With the addition of Water-Right, the Company grew its North America water treatment platform. Water-Right is included in the Company’s North America segment for reporting purposes. The Company paid an aggregate cash purchase price of $107.0 million, net of cash acquired. In addition, the Company established a $4.0 million escrow to satisfy any potential obligations of the former owners of Water-Right, should they arise. The following table summarizes the preliminary estimate of the fair value of the assets acquired and liabilities assumed at the date of acquisition of Water-Right for purposes of allocating the purchase price. The Company is in the process of finalizing the fair value estimates; therefore, the allocation of the purchase price is subject to refinement. The preliminary $57.6 million of acquired identifiable intangible assets was comprised of the following: $38.3 million of customer relationships being amortized over 20 years, $18.2 million of trademarks not subject to amortization, and $1.1 million of non-compete April 8, 2019 (dollars in millions) Current assets, net of cash acquired $ 9.7 Property, plant and equipment 8.6 Intangible assets 57.6 Goodwill 33.7 Total assets acquired 109.6 Current liabilities (2.6 ) Total liabilities assumed (2.6 ) Net assets acquired $ 107.0 The acquisition was accounted for using the purchase method of accounting, and accordingly, the results of operations have been included in the Company’s consolidated financial statements from April 8, 2019, the date of acquisition.

Leases [Abstract]
Leases	4. Leases The Company’s lease portfolio consists of operating leases for buildings and equipment, such as forklifts and copiers, primarily in the United States and China. The Company defines a lease as a contract that gives the Company the right to control the use of a physical asset for a stated term. The Company pays the lessor for that right, with a series of payments defined in the contract and a corresponding right of use operating lease asset and liability are recorded. The Company has elected not to record leases with an initial term of 12 months or less on its condensed consolidated balance sheet. To determine balance sheet amounts, required legal payments are discounted using the Company’s incremental borrowing rate. The incremental borrowing rate is the rate of interest that the Company would incur if it were Certain leases include one or more options to renew or terminate. Renewal terms can extend the lease term from one to five years and options to terminate can be effective within one year. The exercise of lease renewal or termination is at the Company’s discretion and when it is determined to be reasonably certain to renew or terminate, the option is reflected in the measurement of lease asset and liability. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants or material subleases.

Derivative Instruments

Derivative Instruments	9 Months Ended
	Sep. 30, 2019
Derivative Instruments	14. Derivative Instruments The Company utilizes certain derivative instruments to enhance its ability to manage currency exposure as well as raw materials price risk. Derivative instruments are entered into for periods consistent with the related underlying exposures and do not constitute positions independent of those exposures. The Company does not enter into contracts for speculative purposes. The contracts are executed with major financial institutions with no credit loss anticipated for failure of the counterparties to perform. Cash Flow Hedges With the exception of its net investment hedges, the Company designates that all of its hedging instruments are cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), gains or losses on the derivative instrument are reported as a component of other comprehensive loss, net of tax, and are reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. Foreign Currency Forward Contracts The Company is exposed to foreign currency exchange risk as a result of transactions in currencies other than the functional currency of certain subsidiaries. The Company utilizes foreign currency forward purchase and sale contracts to manage the volatility associated with foreign currency purchases, sales and certain intercompany transactions in the normal course of business. Principal currencies for which the Company utilizes foreign currency forward contracts include the British pound, Canadian dollar, Euro and Mexican peso. Gains and losses on these instruments are recorded in accumulated other comprehensive loss, net of tax, until the underlying transaction is recorded in earnings. When the hedged item is realized, gains or losses are reclassified from accumulated other comprehensive loss to the consolidated statement of earnings. The assessment of effectiveness for forward contracts is based on changes in the forward rates. These hedges have been determined to be effective.

For the derivative instruments that are designated and qualify as net investment hedges, gains and losses are reported in other comprehensive loss where they offset gains and losses recorded on the Company’s net investments in its non-U.S. subsidiaries. These hedges are determined to be effective. The Company recognized $ 2.7 million of after-tax gains associated with hedges of a net investment in non-U.S. subsidiaries in currency translation adjustment in other comprehensive income in the three and , respectively . The Company recognized $ million and $ million of after-tax gains associated with hedges of a net investment in non-U.S. subsidiaries in currency translation adjustment in other comprehensive income in the three and nine months ended September 30, 2018, respectively.

Commitments and Contingencies	16. Commitments and Contingencies The Company maintains a commercial relationship with a supply-chain service provider (the Provider) in connection with the Company’s business in China. In this capacity, the Provider offers order-entry, warehousing and logistics support. The Provider also offers asset-backed financing to certain of the Company’s distributors in China to facilitate their working capital needs. To facilitate its financing support business, the Provider has collateralized lending facilities in place with multiple Chinese banks under which the Company has agreed to repurchase inventory if both requested by the banks and certain defined conditions are met, primarily related to the aging of the distributors’ notes. The Provider is required to indemnify the Company for any losses the Company would incur in the event of an inventory repurchase under these arrangements. Potential losses under the repurchase arrangements represent the difference between the repurchase price and net proceeds from the resale of product plus costs incurred in the process, less related distributor rebates. Before considering any reduction of distributor rebate accruals of $17.1 and $25.1 million as of September 30, 2019 and December 31, 2018, respectively, and from the resale of the related inventory, the gross amount the Company would be obligated to repurchase, which would be contingent on the default of all of the outstanding loans, was approximately $56.3 million and $75.8 million as of September 30, 2019 and December 31, 2018, respectively.
