The Corporation and its subsidiaries are involved in various claims and lawsuits incidental to their businesses and are also subject to asbestos litigation as described below.

Claims have been asserted alleging personal injury from exposure to asbestos-containing components historically used in some products manufactured by predecessors of Air & Liquid (the “Asbestos Liability”). Air & Liquid, and in some cases the Corporation, are defendants (among a number of defendants, often in excess of 50) in cases filed in various state and federal courts.

The following table reflects approximate information about the claims for the Asbestos Liability against Air & Liquid and the Corporation for the years ended December 31, 2021, and 2020. The majority of the settlement and defense costs were reported and paid by insurers. Because claims are often filed and can be settled or dismissed in large groups, the amount and timing of settlements, as well as the number of open claims, can fluctuate significantly from period to period.

	2021			2020
Total claims pending at the beginning of the period		5,891			6,102
New claims served		1,233			1,016

In 2021, the Corporation adopted the same methodology used by the liability expert who values the Corporation’s asbestos claims, in order to better align the Corporation’s data with the expert’s liability valuation. The expert’s methodology treats all claims filed six or more years ago as “administratively closed.” Therefore, the Corporation changed its prior practice of reporting “Total claims pending at the end of the period” into two categories – “Administrative closures” and “Total active claims at the end of the period.” Administrative closures now include (i) those claims that were filed six or more years ago; (ii) claims that were previously classified in various jurisdictions as “inactive;” and (iii) claims that were transferred to a state or federal judicial panel on multi-district litigation. Collectively, these claims are unlikely to result in any liability to the Corporation. Accordingly, the Corporation believes that presentation of “Total active claims pending at the end of the period” is a better indicator of total claims which may result in future payment.

The Corporation and Air & Liquid are parties to a series of settlement agreements (“Settlement Agreements”) with insurers that have coverage obligations for the Asbestos Liability (the “Settling Insurers”). Under the Settlement Agreements, the Settling Insurers accept financial responsibility, subject to the terms and conditions of the respective agreements, including overall coverage limits, for pending and future claims for the Asbestos Liability. The Settlement Agreements encompass the majority of insurance policies that provide coverage for claims for the Asbestos Liability.

The Settlement Agreements include acknowledgements that Howden North America, Inc. (“Howden”) is entitled to coverage under policies covering the Asbestos Liability for claims arising out of the historical products manufactured or distributed by Buffalo Forge, a former subsidiary of the Corporation (the “Products”), which was acquired by Howden. The Settlement Agreements do not provide for any prioritization on access to the applicable policies or any sub-limits of liability as to Howden or the Corporation and Air & Liquid and, accordingly, Howden may access the coverage afforded by the Settling Insurers for any covered claim arising out of the Products. In general, access by Howden to the coverage afforded by the Settling Insurers for the Products will erode coverage under the Settlement Agreements available to the Corporation and Air & Liquid for the Asbestos Liability.

At December 31, 2006, with the assistance of a nationally recognized expert in the valuation of asbestos liabilities, the Corporation recorded its initial reserve for the Asbestos Liability. Since then, the Corporation and the expert have reviewed the Asbestos Liability and the underlying assumptions on a regular basis to determine whether any adjustment to the Asbestos Liability or the underlying assumptions were necessary. When warranted, the Asbestos Liability was adjusted to consider the current trends and new information that became available and, if reasonably estimable, to extend the valuation of asbestos liabilities further into the future. In 2018, the valuation was extended to include claims projected to be asserted through 2052, the estimated final date by which the Corporation expects to have settled all asbestos-related claims.

In conjunction with the regular updates of the estimated Asbestos Liability, the Corporation also develops an estimate of defense costs expected to be incurred with settling the Asbestos Liability and probable insurance recoveries for the Asbestos Liability and defense costs. In developing the estimate of probable defense costs, the Corporation considers several factors including, but not limited to, current and historical defense-to-indemnity cost ratios. In developing the estimate of probable insurance recoveries, the Corporation considers the expert’s projection of settlement costs for the Asbestos Liability and management’s projection of associated defense costs. In addition, the Corporation consults with its outside legal counsel on insurance matters and a nationally recognized insurance consulting firm that it retains to assist with certain policy allocation matters. The Corporation also considers a number of other factors

including the Settlement Agreements in effect, policy exclusions, policy limits, policy provisions regarding coverage for defense costs, attachment points, gaps in the coverage, policy exhaustions, the nature of the underlying claims for the Asbestos Liability, estimated erosion of insurance limits on account of claims against Howden arising out of the Products, prior impairment of policies, insolvencies among certain of the insurance carriers, and creditworthiness of the remaining insurers based on publicly available information. Based on these factors, the Corporation estimates the probable insurance recoveries for the Asbestos Liability and defense costs for the corresponding timeframe of the Asbestos Liability.

In 2021, primarily as a result of identified changes in claim data and availability of new information, the Corporation engaged GNARUS Advisors LLC (“GNARUS”) to update the estimated Asbestos Liability. The methodology used by GNARUS in its updated projection was substantially the same methodology employed previously, which has been accepted by numerous courts, and included the following factors:

Based on this analysis, the Corporation recorded an increase to its estimated Asbestos Liability of $23,333 for claims pending or projected to be asserted through 2052. The increase is primarily attributable to recent claim experience, including a higher expected proportion of mesothelioma claims which typically have a higher settlement value, offset by a lower defense-to-indemnity cost ratio (reduced to 70% from 80% based on experience over the past five years) and elimination of an inflationary factor based on historical experience over the past 10+ years which provided no evidence that inflationary pressures influenced settlement averages. In addition, the Corporation increased its estimated insurance receivable by $16,672 for the estimated insurance recoveries attributable to the claims for which the Asbestos Liability reserve has been established and the portion of defense costs covered by the Settlement Agreements. The difference between the increase to the Asbestos Liability and the increase to the insurance receivable of $6,661 is recorded as a charge for asbestos-related costs in the consolidated statement of operations for 2021. In addition, in the prior year, the Corporation recognized expense equaling $283 for the potential insolvency of an insurance carrier, which was recorded as a charge for asbestos-related costs in the consolidated statement of operations for 2020.

The following table summarizes activity relating to insurance recoveries for the years ended December 31, 2021, and 2020.

	2021			2020
Insurance receivable – asbestos, beginning of the year	$	117,937		$	136,932
Settlement and defense costs paid by insurance carriers		(13,312	)		(18,712	)
Change in estimated coverage		16,672			(283	)
Insurance receivable – asbestos, end of the year	$	121,297		$	117,937

The balance of the insurance receivable does not assume any recovery from insolvent carriers. A substantial majority of the insurance recoveries deemed probable is from insurance companies rated A – (excellent) or better by A.M. Best Corporation. There can be no assurance, however, that there will not be insolvencies among the relevant insurance carriers, or that the assumed percentage recoveries for certain carriers will prove correct. The difference between insurance recoveries and projected costs is not due to exhaustion of all insurance coverage for the Asbestos Liability.

The amounts recorded for the Asbestos Liability and insurance receivable rely on assumptions that are based on currently known facts and strategy. The Corporation’s actual expenses or insurance recoveries could be significantly higher or lower than those recorded if assumptions used in the Corporation’s or the experts’ calculations vary significantly from actual results. Key variables in these assumptions are identified above and also include the number and nature of new claims to be filed each year, the average cost of disposing of each new claim, average annual defense costs, compliance by relevant parties with the terms of the Settlement Agreements, and the solvency risk with respect to the relevant insurance carriers. Other factors that may affect the Asbestos Liability and ability to recover under the Corporation’s insurance policies include uncertainties surrounding the litigation process from jurisdiction to jurisdiction and from case to case, reforms that may be made by state and federal courts, and the passage of state or federal tort reform legislation.

The Corporation intends to continue to evaluate the Asbestos Liability and related insurance receivable, as well as the underlying assumptions, on a regular basis to determine whether any adjustments to the estimates are required. Due to the uncertainties surrounding asbestos litigation and insurance, these regular reviews may result in the Corporation adjusting its current reserve;

however, the Corporation is currently unable to estimate such future adjustments. Adjustments, if any, to the Corporation’s estimate of the Asbestos Liability and/or insurance receivable could be material to the operating results for the periods in which the adjustments to the liability or receivable are recorded and to the Corporation’s consolidated financial position and liquidity.
