NTD, N.T.D. or No Third Dividend is when there are not enough starters in a race to pay a third dividend.
8 or more starters in a race will pay 3 place dividends.
If there are between 5 and 7 runners after final scratchings then there will be no third dividend on that race.
If there are 8 or more starters at final scratching time and subsequent late scratchings reduce the field to between 5 and 7 starters then 3 place dividends will still apply.
