Each racing meeting licensee within the commonwealth acting as a guest track and simulcasting a live greyhound race from a host track from outside the commonwealth shall return to the winning patrons all sums so deposited less such breaks and less either an amount not to exceed nineteen percent of the total amount so deposited or an amount which would be paid under the laws of the jurisdiction exercising regulatory authority over such host track; provided, however, that a sum equal to 3/8 of 1 per cent of the total amount wagered shall be paid daily to the commission on behalf of the commonwealth; a sum equal to one-quarter of one percent of the total amount wagered shall be paid to the Greyhound Promotional Trust Fund under the direction and supervision of the state racing commissioners; a sum equal to one-quarter of one percent of the total amount wagered shall be paid to the Greyhound Capital Improvement Trust Fund under the direction and supervision of the state racing commissioners; and the remaining percentages shall be retained by the racing meeting licensee as his commission; provided, however, that not less than three and one-half percent shall be paid to the dog owners for purses, and the remaining portion shall be applied to the expenses as the racing meeting licensee is required to pay pursuant to contracts negotiated with the host track. All such contracts shall be subject to the approval of the recognized greyhound owners association of the most recent live racing performance at the guest track.
In no case shall a person or association licensed to conduct a dog racing meeting serve as a guest or host track for the purpose of simulcasting a race unless the licensee has received the prior approval of the greyhound owners association at the licensees facility and such approval is on file with the commission.
