Other noncurrent liabilities include reserves for the Redux and Pondimin litigation (see Note 10), reserves relating to income taxes, environmental matters, product liability and other litigation, as well as restructuring, pension and other employee benefit liabilities, and minority interests.

The Company has responsibility for environmental, safety and cleanup obligations under various local, state and federal laws, including the Comprehensive Environmental Response, Compensation and Liability Act, commonly known as Superfund. At December 31, 2000, the Company was a party to, or otherwise involved in, legal proceedings directed at the cleanup of 59 Superfund sites.

It is the Company's policy to accrue for environmental cleanup costs if it is probable that a liability has been incurred and an amount is reasonably estimable. In many cases, future environmental-related expenditures cannot be quantified with a reasonable degree of accuracy. Environmental expenditures that relate to an existing condition caused by past operations that do not contribute to current or future results of operations are expensed. As investigations and cleanups proceed, environmental-related liabilities are reviewed and adjusted as additional information becomes available. The aggregate environmental-related accruals were $378,570,000 and $359,190,000 at December 31, 2000 and 1999, respectively. Environmental-related accruals have been recorded without giving effect to any possible future insurance proceeds or the timing of payments. See Note 10 for a discussion of contingencies.

In 2000, the Company introduced a new incentive program to employees, the Performance Incentive Award Program (PIA), based on the Company's operating results and the individual employees' performance. Substantially all U.S. and Puerto Rico exempt employees, who are not subject to other incentive programs, and key international employees are eligible to receive cash awards under PIA. The value of PIA awards for 2000 was $94,658,000. In 1999, cash bonuses totaling $38,773,000 were paid to key employees. In 1998, the Company provided incentive awards under the Management Incentive Plan (MIP), which provides for cash and deferred contingent common stock awards to key employees. The value of MIP awards for 1998 was $56,892,000, which included deferred contingent common stock of $14,261,000 (261,256 shares). Deferred contingent common stock awards plus accrued dividends totaling 1,104,340 shares were outstanding at December 31, 2000.
