NOTES TO CONSOLIDATED FINANCIAL STATEMENTS LiabilityEstimate. With the assistance of HR&A, effective as of December 31, 2011, the Company updated and extended its estimate of the asbestos liability, including the costs of settlement or indemnity payments and defense costs relating to currently pend- ing claims and future claims projected to be filed against the Com- pany through 2021. The Company’s previous estimate was for asbestos claims filed or projected to be filed through 2017. As a result of this updated estimate, the Company recorded an additional liability of $285 million as of December 31, 2011. The Company’s decision to take this action at such date was based on several factors which contribute to the Company’s ability to reasonably estimate this liability for the additional period noted. First, the number of mesothelioma claims (which although constituting approximately 8% of the Company’s total pending asbestos claims, have accounted for approximately 90% of the Company’s aggregate settlement and defense costs) being filed against the Company and associated set- tlement costs have recently stabilized. In the Company’s opinion, the outlook for mesothelioma claims expected to be filed and resolved in the forecast period is reasonably stable. Second, there have been favorable developments in the trend of case law which has been a contributing factor in stabilizing the asbestos claims activity and related settlement costs. Third, there have been sig- nificant actions taken by certain state legislatures and courts over the past several years that have reduced the number and types of claims that can proceed to trial, which has been a significant factor in stabilizing the asbestos claims activity. Fourth, the Company has now entered into coverage-in-place agreements with almost all of its excess insurers, which enables the Company to project a more stable relationship between settlement and defense costs paid by the Company and reimbursements from its insurers. Taking all of these factors into account, the Company believes that it can reasonably estimate the asbestos liability for pending claims and future claims to be filed through 2021. While it is probable that the Company will incur additional charges for asbestos liabilities and defense costs in excess of the amounts currently provided, the Company does not believe that any such amount can be reasonably estimated beyond 2021. Accordingly, no accrual has been recorded for any costs which may be incurred for claims which may be made subsequent to 2021. by numerous courts. After discussions with the Company, HR&A augments its liability estimate for the costs of defending asbestos claims in the tort system using a forecast from the Company which is based upon discussions with its defense counsel. Based on this information, HR&A compiles an estimate of the Company’s asbes- tos liability for pending and future claims, based on claim experi- ence during the reference period and covering claims expected to be filed through the indicated forecast period. The most significant factors affecting the liability estimate are (1) the number of new mesothelioma claims filed against the Company, (2) the average settlement costs for mesothelioma claims, (3) the percentage of mesothelioma claims dismissed against the Company and (4) the aggregate defense costs incurred by the Company. These factors are interdependent, and no one factor predominates in determining the liability estimate. Although the methodology used by HR&A can be applied to show claims and costs for periods subsequent to the indicated period (up to and including the endpoint of the asbestos studies referred to above), management believes that the level of uncertainty regarding the various factors used in estimating future asbestos costs is too great to provide for reasonable estimation of the number of future claims, the nature of such claims or the cost to resolve them for years beyond the indicated estimate. In the Company’s view, the forecast period used to provide the best estimate for asbestos claims and related liabilities and costs is a judgment based upon a number of trend factors, including the number and type of claims being filed each year; the jurisdictions where such claims are filed, and the effect of any legislation or judicial orders in such jurisdictions restricting the types of claims that can proceed to trial on the merits; and the likelihood of any comprehensive asbestos legislation at the federal level. In addition, the dynamics of asbestos litigation in the tort system have been significantly affected over the past five to ten years by the sub- stantial number of companies that have filed for bankruptcy pro- tection, thereby staying any asbestos claims against them until the conclusion of such proceedings, and the establishment of a number of post-bankruptcy trusts for asbestos claimants, which are esti- mated to provide $36 billion for payments to current and future claimants. These trend factors have both positive and negative effects on the dynamics of asbestos litigation in the tort system and the related best estimate of the Company’s asbestos liability, and these effects do not move in a linear fashion but rather change over multi-year periods. Accordingly, the Company’s management con- tinues to monitor these trend factors over time and periodically assesses whether an alternative forecast period is appropriate. Management has made its best estimate of the costs through 2021 based on the analysis by HR&A completed in January 2012. Through December 31, 2012, the Company’s actual experience during the updated reference period for mesothelioma claims filed and dis- missed generally approximated the assumptions in the Company’s liability estimate. In addition to this claims experience, the Com- pany considered additional quantitative and qualitative factors such as the nature of the aging of pending claims, significant appellate rulings and legislative developments, and their respective effects on expected future settlement values. Based on this evaluation, the Company determined that no change in the estimate was warranted for the period ended December 31, 2012. Nevertheless, if certain factors show a pattern of sustained increase or decrease, the liability could change materially; however, all the assumptions used in estimating the asbestos liability are interdependent and no sin- gle factor predominates in determining the liability estimate. Because of the uncertainty with regard to and the interdependency of such factors used in the calculation of its asbestos liability, and since no one factor predominates, the Company believes that a range of potential liability estimates beyond the indicated forecast period cannot be reasonably estimated. Each quarter, HR&A compiles an update based upon the Company’s experience in claims filed, settled and dismissed during the updated reference period (consisting of the preceding eleven quar- terly periods) as well as average settlement costs by disease category (mesothelioma, lung cancer, other cancer, and other non- malignant conditions including asbestosis) during that period. In addition to this claims experience, the Company also considers additional quantitative and qualitative factors such as the nature of the aging of pending claims, significant appellate rulings and legis- lative developments, and their respective effects on expected future settlement values. As part of this process, the Company also takes into account trends in the tort system such as those enumerated above. Management considers all these factors in conjunction with the liability estimate of HR&A and determines whether a change in the estimate is warranted. 54
