Mortgage brokers were left wondering yesterday whether they would have Rams mortgage products on their books and what those products would look like if Westpac's proposed deal to buy the Rams brand and franchise network goes ahead. Brokers generated $3.6 billion of settled loans for Rams in the 12 months to March this year - more than twice the $1.7 billion of settled loans that came through the franchise network.Despite their importance to the business, brokers said they knew almost nothing about what was going on. One broker told The Sheet his company had received an email in the morning. Another said he was calling around asking if anyone knew what was going on.Mortgage Choice spokesman Warren O'Rourke said his group put in calls yesterday but by the end of day had no real information.The email that went out to brokers yesterday said: "Operationally and contractually, for brokers it should seem like there hasn't been a big change. Brokers can continue to work with the same servicing team that you're used to, and sell RAMS branded products. "During the transitional period, Westpac will have input into credit policies but we expect that most Rams business processes will be retained. After completion of the Westpac acquisition, Westpac will determine business processes, but they have indicated that they want to keep Rams as a standalone business."Asked at a press briefing yesterday what the position was for brokers, Rams chief executive Greg Kolivos said he expected things would remain "very much unchanged".That seems unlikely. Westpac plans to offer its own loan products, re-badged as Rams loans, through the franchise network. Will it offer the same package to brokers? Will the pricing and features be the same as for Westpac branded loans? When those questions were put to Westpac yesterday a spokesperson responded by saying: "It is probably too early to comment on the integration of the Rams business into Westpac, including third party channels. That will be determined once we complete the transaction."Rams loans originated by brokers were 48 per cent low doc in the year to March. This is quite a different mix to loans originated through the franchise network, which were 24 per cent low doc and 32 per cent Easy Start (a loan that starts on a discounted rate and steps up to the full rate over three years). Westpac is not renowned as an aggressive player in the low doc segment.
