PURPOSE: This rule sets forth the definitions and calculations of the show pool.

1. (1) The amounts wagered to show on the first three (3) horses to finish are deducted from the net pool to determine the profit; the profit is divided into three (3) equal amounts; one-third (1/3) of the profit is divided by the amount wagered to show on the first finisher, the quotient being the profit per dollar wagered to show on the first finisher; onethird (1/3) of the profit is divided by the amount wagered to show on the second finisher, the quotient being the profit per dollar wagered to show on the second finisher; and one-third (1/3) of the profit is divided by the amount wagered to show on the third finisher, the quotient being the profit per dollar wagered to show on the third finisher; payoffs include return of amount wagered and profit as to each of the first three (3) finishers.
2. (2) In the event of a dead heat for first— because two (2) horses involving different betting interests or three (3) horses involving three (3) different betting interests— the show pool is distributed as if no dead heat occurred; if between two (2) horses involving the same betting interest, two-thirds (2/3) of the profit is allocated to wagers to show on the coupled betting interest and one-third (1/3) allocated to wagers to show on the other horse among the first three (3) finishers; if between three (3) horses involving one (1) betting interest, the show pool is distributed as if a win pool.
3. (3) In the event of a dead heat for second— between two (2) horses involving two (2) different betting interests—the show pool is distributed as if no dead heat occurred; if between horses involving the same betting interest, two-thirds (2/3) of the profit shall be allocated to wagers to show on the coupled betting interest and one-third (1/3) allocated to wagers to show on the horse finishing first; if between three (3) horses involving two (2) or three (3) betting interests, one-third (1/3) of the profit is allocated to wagers to show on the horse finishing first and the remaining two-thirds (2/3) of the profit is divided equally by the number of betting interests finishing in a dead heat for second for proportionate distribution on wagers to show for each betting interest finishing in a dead heat for second.
4. (4) In the event of a dead heat for third— between horses involving the same betting interests—the show pool is distributed as if no dead heat occurred; if between horses involving two (2) or more betting interests, two-thirds (2/3) of the profit shall be allocated to wagers to show on the first two (2) finishers and the remaining one-third (1/3) is divided equally by the number of betting interests finishing in a dead heat for third for proportionate distribution on wagers to show for each of the betting interests finishing in a dead heat for third.
5. (5) In the event the first three (3) horses to finish comprise one (1) betting interest, the show pool shall be distributed as win pool. In the event two (2) horses comprising a coupled betting interest finish first and second, or first and third, or second and third, two-thirds (2/3) of the profit shall be allocated to wagers to show on the other horse among the first three (3) finishers.
6. (6) In the event one (1) horse of a coupled betting interest finishes first or second and another horse included in the same betting interest finishes in a dead heat for third; onehalf (1/2) of the profit in the show pool shall be allocated to wagers on coupled betting interest, one-third (1/3) of the profit in the show pool shall be allocated to wagers on the horse finishing first or second and the remaining one-sixth (1/6) of the profit shall be allocated to wagers on the horse finishing in a dead heat for third with coupled betting interest.
7. (7) In the event only two (2) horses finish, the show pool, if any, shall be distributed as if a place pool; if only one (1) horse finishes, the place and show pools, if any, shall be distributed as if a win pool; if no horse finishes, all money wagered on the race shall be refunded upon presentation and surrender of pari-mutuel tickets sold on that race. In the event no show ticket is sold on a horse which finishes first or second or third, then, the horse which finished fourth shall replace that horse in the distribution of wager in the show pool.
