On December 31, 2013, what amount would HU show as the balance in an unearned revenue account for the gift cards?
HU Photoshop sold $1000 in gift cards on a special promotion on October 15, 2013, and sold $1,500 in gift cards on another special promotion on November 15, 2013. Of the cards sold in October, $100 were redeemed in October, $250 in November, and $300 in December. Of the cards sold in November, $150 were redeemed in November and $350 were redeemed in December. HU views the probability of redemption of a gift card as remote if the card has not been redeemed within two months.
