The DRF is put in place to protect the exchange and its account holders. Every account holder pays an annual card fee of £200 BBX and out of that payment £100 BBX is deposited into a dedicated DRF account. It is a fund which is ring fenced and only called upon to cover a bad debt left by an account holder. What this means is that if an account holder having borrowed BBX£ using their interest free credit line facility subsequently defaults and BBX have done all they can to recover the debt but have been unsuccessful then BBX will draw on the Debt Reserve Fund to make good the outstanding debt. This means that provided an authorization is obtained at the point of sale there are no bad debts or accounts receivable ! The DRF is NOT available for consumer dispute resolution.
