The Dragic Corporation is trying to decide whether to switch to a bank that will accommodate electronic funds transfers from Dragic's customers. Dragic's financial manager believes the new system would decrease its collection float by as much a s four days. The new bank would require a compensating balance of $1,000,000, whereas its present bank has no compensating balance requirement. Dragic's average daily collections are $500,000, and it can earn 7% on it short-term investments. Should Dragic make the switch? (Assume the compensating balance at the new bank will be deposited in a non-interest earning account.)
