Accounting Policies [Abstract]

Consolidation

Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation.

Cash Equivalents

Cash Equivalents

The Company considers all highly liquid investments with original maturities of ninety days or less to be cash equivalents.

Receivables

Receivables

Receivables consist primarily of trade receivables. The Company does not require collateral or other security and evaluates the collectability of its receivables based on a number of factors. An allowance for doubtful accounts is recorded for significant past due receivable balances based on a review of the past due items and the customer's ability and likelihood to pay, as well as applying a historical write-off ratio to the remaining balances. Changes in the Company's allowance for doubtful accounts are as follows:

	Balance at beginning of year		Provision and reserve adjustments			Write-offs less recoveries			Balance at end of year
	(In thousands)
2025	$	2,980	$	(44	)	$	(449	)	$	2,487
2024		2,904		275			(199	)		2,980
2023		1,179		1,862			(137	)		2,904

Inventories

Inventories

Inventories are valued at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method. The Company estimates and records provisions for obsolete and excess inventories. Changes to the Company's obsolete and excess inventories reserve are as follows:

	Balance at beginning of year		Net additions charged to earnings		Disposals			Balance at end of year
	(In thousands)
2025	$	8,485	$	3,354	$	(2,353	)	$	9,486
2024		6,874		4,023		(2,412	)		8,485
2023		6,681		2,135		(1,942	)		6,874

Property, Plant and Equipment

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation is provided over the estimated useful lives of the respective assets by the straight-line method. The estimated useful lives of assets are: for land improvements, 15 years; for buildings and improvements, 10 to 39 years; and for machinery and equipment, 3 to 20 years.

Capitalized Software and Hardware

Capitalized Software and Hardware

Capitalized internal use software and hardware included in other assets in the Consolidated Balance Sheets were $3.7 million and $3.8 million at December 31, 2025 and 2024, respectively. These amounts are amortized on a straight-line basis over the estimated useful lives of the software and/or hardware, ranging from 1 to 5 years. Amortization expense recognized for the years ending December 31, 2025, 2024 and 2023 was $3.5 million, $3.4 million and $3.3 million, respectively.

Long-Lived Assets

Long-Lived Assets

Property, plant and equipment and identifiable intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected undiscounted cash flows is less than the carrying value of the related asset or group of assets, a loss is recognized for the difference between the fair value and carrying value of the asset or group of assets.

Intangible Assets

Intangible Assets

Intangible assets are amortized on a straight-line basis over their estimated useful lives, ranging from 5 to 20 years. The Company does not have any intangible assets deemed to have indefinite lives. Amortization expense was $14.7 million in 2025, $9.1 million in 2024 and $8.6 million in 2023. Amortization expense expected to be recognized is $14.4 million in 2026, $11.7 in 2027, $10.4 million in 2028, $9.9 million in 2029, $9.1 million in 2030 and $63.0 million thereafter. The carrying value and accumulated amortization by major class of intangible assets are as follows:

Goodwill

Goodwill

Goodwill is tested for impairment annually during the fourth quarter or more frequently if an event indicates that the goodwill might be impaired. Potential impairment is identified by comparing the fair value of a reporting unit with its carrying value. No adjustments were recorded to goodwill as a result of these tests during 2025, 2024 and 2023. Goodwill was $235.6 million at December 31, 2025 and $111.8 million at December 31, 2024. The change in goodwill from 2024 to 2025 resulted from currency translation adjustments of $5.5 million and the acquisition of SmartCover of $118.3 million. This acquisition is further described in Note 3 “Acquisitions”.

Warranty and After-Sale Costs

Warranty and After-Sale Costs

The Company estimates and records provisions for warranties and other after-sale costs in the period in which the sale is recorded, based on a lag factor and historical warranty claim experience. After-sale costs represent a variety of activities outside of the written warranty policy, such as investigation of unanticipated issues after the customer has installed the product or analysis of water quality issues. Changes in the Company's warranty and after-sale costs reserve are as follows:

	Balance at beginning of year		Provision of acquired business		Net additions charged to earnings		Costs incurred			Balance at end of year
	(In thousands)
2025	$	16,693	$	607	$	12,933	$	(8,659	)	$	21,574

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Fair Value Measurements of Financial Instruments

Fair Value Measurements of Financial Instruments

The carrying amounts of cash and cash equivalents, receivables and payables in the financial statements approximate their fair values due to the short-term nature of these financial instruments. Included in other assets are insurance policies on various individuals who were associated with the Company. The carrying amounts of these insurance policies approximate their fair value.

Subsequent Events

Subsequent Events

The Company evaluates subsequent events at the date of the balance sheet as well as conditions that arise after the balance sheet date but before 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, if any, disclosures are made regarding the nature of events and the estimated financial effects for those events and conditions. For purposes of preparing the accompanying consolidated financial statements and the notes to these financial statements, the Company evaluated subsequent events through the date the accompanying financial statements were issued.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures," which requires additional disclosure associated with the effective tax rate reconciliation and payment of income taxes. The guidance is effective for fiscal years beginning after December 15, 2025 and can be applied on a prospective basis

with the option to apply the standard retrospectively. The Company adopted ASU No. 2023-09 on December 31, 2025, applying the standard on a retrospective basis, the impact of which was not significant to the Company or its related disclosures.

In November 2024, the FASB issued ASU No. 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosure," which requires additional disclosure of specified information about certain costs and expense categories.

The Company is currently assessing the impact of this proposed change on its consolidated financial statements.

In September 2025, the FASB issued ASU No. 2025-06, "Targeted Improvements to the Accounting for Internal-Use Software," which removes the development stage requirements and implements a probable-to-complete recognition threshold associated with capitalization of internal use software costs. This guidance is effective for fiscal years beginning after December 15, 2027 and interim periods within those reporting periods. Early adoption is permitted in an interim or annual reporting period in which financial statements have not yet been made available for issuance. The Company is currently assessing the impact of this proposed changed on its consolidated financial statements.

In December 2025, the FASB issued ASU No. 2025-11, "Interim Reporting (Topic 270): Narrow-scope improvements."
