N.Y. Comp. Codes R. & Regs. tit. 9, § 5329.15
A casino sports wagering licensee may, in its discretion, accept a layoff wager from another New York State-licensed casino sports wagering licensee or skin, as skin is defined in section 5330.1 of this Title. Any such wager shall be placed in the name of the casino sports wagering licensee itself or skin itself. A layoff wager and, if applicable, a resultant payout shall not be included in the calculation of sports pool gross gaming revenue. Each layoff wager shall be reported to the commission, if possible, prior to the placement of such wager. If not possible, a casino sports wagering licensee or skin shall submit the details of the layoff wager to the commission’s division of gaming within 24 hours of the placement of such wager. Layoff wagers shall not be executed with operators in other jurisdictions unless all Federal law requirements are met.
