Commonwealth Bank will be hoping to grab a bigger share of the self-managed superannuation market with its acquisition of Count Financial.Count announced yesterday that it had received an offer of A$1.40 a share from Commonwealth, pricing the company on a multiple of 14.6 times its 2010/11 earnings and an equity value of $373 million.Count shareholders will be able to take cash or the equivalent in CBA shares. Count's directors have recommended the deal.The transaction is being done by 'scheme of arrangement' and will need court approval. Commonwealth has given undertakings that Count will continue to operate as a standalone business and will maintain established relationships with service providers.Count provides financial planning services to a network of several hundred accountants. Accountants are the primary source of advice for self-managed super fund trustees.Count administers $6.2 billion through several investment platforms, plus $3.6 billion of "other funds". It has $3.4 billion of residential and commercial loans in a loan broking division and $47.5 million of in-force life insurance premiums.Commonwealth has good reason to want to tap into the SMSF market. While most parts of the wealth management market have been flat over the past year, self-managed super has continued to grow. According to Australian Taxation Office figures, the number of SMSFs increased 7.7 per cent, to 456,472, in the year to June. Assets in SMSFs grew by 12 per cent, to $418 billion, over the same period.Self-managed fund trustees are big investors in cash and term deposits, with more than 25 per cent of their investment allocations in these assets. Banks are looking for more deposit funding to reduce their exposure to wholesale markets and SMSFs look like a good market.
