# Non-Runner Rules

I bet on a non-runner, what happens to my bet?

• Bets placed on Antepost markets will be settled as losing bets.
• Bets placed on Day of the Race markets will have their stakes returned once the non-runner is declared.
• If you have placed an accumulator, the line related to the non-runner will be void, you will receive your stake for that line back. The rest of the lines in the accumulator will still stand.

My bet was a winner, what are non-runner deductions?
When you place your bet, the price you see is based on all horses running in the race. If a horse is a non-runner, the price will be revised and a deduction applied for the remaining horses.

Non-Runner deductions will differ based on whether you have placed a bet on the Sportsbook or Exchange.

Sportsbook 'Rule 4' deductions
Sportsbook treats non-runners the same as every other bookmaker, by applying a 'Rule 4'.
The 'Rule 4' deduction values are an industry standard, deductions are measured by a number of pence in the £, based on the odds of the horse at the point of withdrawal.

 Odds From Odds To Deductions (p in £) 1/9 or Shorter 90p 2/11 2/17 85p 1/4 1/5 80p 3/10 2/7 75p 2/5 1/3 70p 8/15 4/9 65p 8/13 4/7 60p 4/5 4/6 55p 20/21 5/6 50p Evens (1/1) 6/5 45p 5/4 6/4 40p 13/8 7/4 35p 15/8 9/4 30p 5/2 3/1 25p 10/3 4/1 20p 9/2 11/2 15p 6/1 9/1 10p 10/1 14/1 5p

 Example: If you had a bet on a horse for £10 at 10/1 that went on to win, but in the same race the favourite (priced at 2/5) pulled out, your total return would be: Pre 'Rule 4' £10 x 10 = £100 (profit pre 'Rule 4') £100 + £10 = £110 (total return pre 'Rule 4') Post Rule 4 £100 less 70% (70p in the £) = £30 (profit post 'Rule 4') £30 + £10 = £40 (total return post 'Rule 4')

Exchange Reduction Factor
Each horse is allocated a reduction factor, based on its likely chance of winning the race. Should a horse be declared a non-runner, the reduction factor will be applied to the prices of all matched bets, for both backers and layers.

This is to ensure that players are not unfairly treated and exposed to large liabilities when the chances of other horses winning have improved. The reduction factors are designed to be fair to both backers and layers.
