POSB is inviting over 1,000 customers to watch the Formula One (F1) race this weekend, it said on Wednesday.
"Invitations have been extended based on a combination of criteria, including the length and depth of a customer or their family's relationship with POSB," it said in a press release.
The bank also recently raised over $1.1 million for children at the POSB PAssion Run for Kids 2013.
