Waterway Frosted Flakes Company offers its customers a pottery cereal bowl if they send in 3 boxtops from Waterway Frosted Flakes boxes and $2. The company estimates that 60% of the boxtops will be redeemed. In 2018, the company sold 1365000 boxes of Frosted Flakes and customers redeemed 660000 boxtops receiving 220000 bowls. If the bowls cost Waterway Company $4 each, how much liability for outstanding premiums should be recorded at the end of 2018?
