[1] As of January 1, 2010, the Company was named in 36,448 maritime actions which had been administratively dismissed by the United States District Court for the Eastern District of Pennsylvania ("MARDOC claims"), and therefore were not classified as active claims. In addition, the Company was named in 8 new maritime actions in 2010 (also not classified as active claims). Through December 31, 2013, pursuant to an ongoing review process initiated by the Court, 26,562 claims were permanently dismissed, and 3,393 claims were classified as active, of which 2,980 claims were subsequently dismissed, 225 claims were subsequently settled and 188 claims remain active (and have been added to "Ending claims"). By settlement agreement of December 30, 2013, the Company resolved all of the remaining MARDOC claims with plaintiffs’ counsel. The agreement will result in the dismissal of all MARDOC claims against the Company.
