Issuing the following statement, Vertex said: “Vertex is entering a 30-day consultation period with employees working on its db mortgages account.
"db mortgages has reviewed its strategy within the mortgage market for 2008 and will be implementing a revised business model in 2008 which will require the reduction of costs within its business.
"Up to 55 jobs are potentially at risk across the marketing, sales, underwriting and risk functions. This move has been necessitated by the current conditions in the mortgage market.
