Uncertainty about future asbestos claims and jury awards has caused much of the recent volatility in our stock price and recent downgrades in our credit ratings. We have not accrued reserves for unknown claims that may be asserted against us in the future. We have not had sufficient information to make a reasonable estimate of future claims. However, we recently retained a leading claim evaluation firm to assist us in making an estimate of our potential liability for asbestos claims that may be asserted against us in the future. When the evaluation firm’s analysis is completed it is likely that we will accrue a material liability for future claims that may be asserted against us. We expect the analysis will be completed during the second quarter of 2002 and that we will accrue the liability at the end of the quarter. At the same time we will accrue a receivable for related insurance proceeds we expect to collect when future claims are actually paid. Litigation. We are currently involved in other legal proceedings not involving asbestos. As discussed in Note 9 of our consolidated financial statements, as of December 31, 2001, we have accrued an estimate of the probable costs for the resolution of these claims. Attorneys in our legal department specializing in litigation claims, monitor and manage all claims filed against us. The estimate of probable costs related to these claims is developed in consultation with outside legal counsel representing us in the defense of these claims. Our estimates are based upon an analysis of potential results, assuming a combination of litigation and settlement strategies. We attempt to resolve claims through mediation and arbitration where possible. If the actual settlement costs and final judgments, after appeals, differ from our estimates, our future financial results may be adversely affected. LONG-TERM CONTRACTUAL OBLIGATIONS AND COMMERCIAL COMMITMENTS The following table summarizes our various long-term contractual obligations: In addition to these long-term contractual obligations, we have other commercial commitments that could become contractual obligations. We also have $700 million of committed lines of credit from banks that are available if we maintain an investment grade rating. Investment grade ratings are BBB- or higher for Standard & Poor’s and Baa3 or higher for Moody’s Investors’ Services and we are currently above these levels. In the normal course of business we have agreements with banks under which approximately $1.4 billion of letters of credit or bank guarantees were issued, including $241 million which relate to our joint ventures’ operations. In addition, $320 million of these financial instruments include provisions that allow the banks to require cash collateralization if debt ratings of either rating agency falls below the rating of BBB by Standard & Poor’s or Baa2 by Moody’s Investors’ Services and $149 million where banks may require cash collateralization if either debt rating falls below investment grade. These letters of credit and bank guarantees relate to our guaranteed performance or retention payments under our long-term contracts and self-insurance. In the past, no significant claims have been made against these financial instruments. We do not anticipate material losses to occur as a result of these financial instruments.
