It is in commemoration of the Feast day of St. Lorenzo Ruiz, Patron of the Philippines and of the URSUMCO plant as well. Like any fiesta across the archipelago, the celebration is decked with revelry, excitement and fun. Employees take a day off from work to participate in the festivities which include parlor games, dances, dinner and raffles. As dusk falls, employees get merry as they groove to the party beat of live band music.
