First National Building Society is expected to make its debut on the Dublin market in the coming months, a move which will benefit its members.

It has indicated that up to 22,000 of the society's borrowers and savers stand to gain free shares when the flotation takes place.

To qualify, customers must have at least £100 in an investment share account for up to two years before the formal conversion is announced or have a mortgage balance of at least £500 at a date to be within the next two months. First National employees will also get free shares.
