Lizzie Shoes' experience, gift cards that have not been redeemed within 12 months are not probable to be redeemed. Lizzie Shoes sold gift cards for $18,000 through August of 2013. $4,000 of cards were redeemed in September of 2013, $3,000 in October, $2,500 in November, and $2,000 in December of 2013. In 2014 an additional $1,000 of cards were redeemed in January and $500 in February.
Explain how much gift card revenue related to with the August 2013 gift card sales would Lizzie get to recognize in 2013 and 2014?
