Exchange: What happens to a Betfair Starting Price (BSP) bet if there is a late non-runner?

If you place a Betfair Staring Price (BSP) bet and we are unable to remove the non runner until after the race has completed, we will delay settlement of the market whilst we manually reconcile the Starting Price. To do this we apply the non runner's reduction factor to the original SP odds generated. This will return new, revised odds for your bet.

This instance rarely occurs, usually when a horse is withdrawn very close to the off of a race and we are unable to remove the non runner from the market before the race is off.
