Flavor Food Company distributes to consumers coupons which may be presented (on or before a stated expiration date) to grocers for discounts on certain products of Flavor. The grocers are reimbursed when they send the coupons to Flavor. In Flavor's experience, 50% of such coupons are redeemed, and generally one month elapses between the date a grocer receives a coupon from a consumer and the date Flavor receives it. During 2018 Flavor issued two separate series of coupons as follows: Consumer Amount Disbursed Issued On Total Value Expiration Date as of 12/31/18 1/1/18 $500,000 6/30/18 $236,000 7/1/18 840,000 12/31/18 350,000 The only journal entry recorded to date is: debit to coupon expense and credit to cash of $815,000. The December 31, 2018 balance sheet should include a liability for unredeemed coupons of:

a) $0.
b) $70,000.
c) $184,000.
d) $420,000.
