Faith Campbell (plaintiff) and her three children, Jazmin, Alteasha, and Clarence Campbell (plaintiffs), sued Kormal and Tajwattie Singh (defendants) and Metropolitan Property and Casualty Insurance Company (Metropolitan) (defendant) for personal injuries to the three children resulting from lead paint in the Singhs’ apartment building where the Campbells resided. Pursuant to a settlement agreement, Metropolitan conceded liability for two policy periods but contested liability for a different period. After a trial, the United States District Court for the Southern District of New York found that Metropolitan was liable for the contested period. The district court awarded the Campbells the full amount of the policy for the contested period, plus prejudgment interest. Metropolitan appealed, contending that the award of prejudgment interest was erroneous.
