The advertised estimated jackpot represents the total payments that would be paid to jackpot winner(s) should they accept the annuity option. This estimate is based on the funds accumulated in the jackpot pool rolled over from prior drawings, expected sales for the next drawing, and market interest rates for the securities that would be used to fund the annuity.[2] The estimated jackpot usually is 32.5% of the (non-Power Play) revenue of each base ($1) play, submitted by game members to accumulate into a prize pool to fund the jackpot. If the jackpot is not won in a particular drawing, the prize pool carries over to the next drawing, accumulating until there is a jackpot winner. This prize pool is the cash that is paid to a jackpot winner if they choose cash. If the winner chooses the annuity, current market rates are used to calculate the graduated payment schedule and the initial installment is paid. The remaining funds in the prize pool are invested to generate the income required to fund the remaining installments. If there are multiple jackpot winners for a drawing, the jackpot prize pool is divided equally for all such plays.
