Most banks maintain some form of customers' securities service for the purpose of safekeeping any securities that customers may feel inclined to leave with them, not as collateral, but simply as deposits of securities. This is a common service done by banks for their customers, but it involves not only recording and safely keeping the securities, but looking after their transfer when necessary, and the collection of any coupons and dividends which may accrue on them. Owing to the value of the property handled and the importance of following up for the customers' benefit any security matters which may require it, good records for this business are essential.
