(CNN) -- The share price of Samsung Electronics dropped nearly 7.5% in trading Monday as investors had their first opportunity to react to the more than $1 billion decision against the Korean electronics giant by a California jury for infringing on Apple patents. Samsung dropped 6.3% at the open of South Korea's Kospi index and finished the day down 7.45%, after dropping as much as 7.7%. The tumble erased about $12 billion from the company's market value Monday. Samsung is planning to appeal Friday's decision of a U.S. federal jury which awarded Apple $1.05 billion for copying the look and feel of iPhones and iPad design. The jury rejected Samsung's counterclaims against Apple.
