Cornish, who expects the market to be 'subdued' this year, said the society had avoided 'riskier' areas pursued by other lenders - such as buy-to-let, agreeing mortgages larger than the value of homes or offering money to people with poor credit track records, a market known as 'sub-prime'. Overall arrears and repossession fell to just 0.004% of total Yorkshire mortgage balances, down from 0.006% a year earlier.
