Growing revenue by expanding the business is top of mind for a couple of the more dynamic mutual ADIs in New South Wales.Newcastle Permanent - styled by its board chair Michael Slater as "the financially strongest customer-owned banking institution in Australia" - is moving west.It is making plans to expand into the central west region of New South Wales, and will open branches in Orange, Bathurst, Mudgee and Dubbo.NPBS reported a net profit of A$39.1 million in the year to June 2013, down $700,000 on the year before.Slater wrote in the annual report that this profit was "particularly significant given the less than favourable market conditions and the highly competitive environment." NPBS achieved growth in assets and deposits over the year close to system, with home loan approvals of more than $1.2 billion. Terry Millett, CEO of Newcastle Permanent, highlighted "the continuing and intense pressure" on deposit pricing from the major banks "as they aim to lessen their dependence on wholesale funding by increasing retail deposits."Catherine Hallinan, chair of Gateway Credit Union in Sydney, wrote in the mutual's annual report that "lenders were locked in a war of attrition, grinding down mortgage rates in an effort to steal customers from each other. The major banks fight hard to prevent rivals, like credit unions, from taking a bigger share."She said that "in a market driven by price discounting, growth came at reduced margins."Gateway recorded a net profit of $2.5 million, up from $1.7 million the previous year. The credit union said an "increasing number of the loans we funded were originated via mortgage brokers", including Connective, Mortgage Choice and Yellow Brick Road.Gateway also made some interesting disclosures regarding liquidity management.Chief executive Paul Thomas said its liquidity "ran at an average of 15.1 per cent, which is ahead of regulatory requirements."However, in August, Gateway did not renew a $50 million committed standby facility from Commonwealth Bank.It said "this was a result of Basel III regulatory requirements in regard to liquidity making such standby arrangements significantly more expensive."
