JP Morgan managers sold 1,200 colourful reindeer antlers to raise $100,000 for Operation Santa Claus, pushing the global financial services firm's total donation to $200,000.
Despite busy schedules, managers from 10 departments tested their fund-raising skills by selling the headgear to staff.
The credit and rates department raised the highest amount of $23,000, followed by the equities and private bank sections which raised $20,000 and $10,000 respectively.
Senior country officer Andrew Kuo said he was proud of the company's achievements.
'We are proud of how generous our employees have been. JP Morgan has always been a keen supporter of children's charities and this year is no different,' he said.
Bruce Salzer, business manager of economic research and market strategy in Asia, said the credit and rates team created a charity raffle as part of a staff Christmas party, attended by about 80 people.
