The Fremont $($Ireland$)$ Flyers were a semi$-$professional carriage racing team that competed up until the early $1930\text{'}$s$.$ Mary Smith owns the Fremont Flyers' trademark, and recently licensed it to the Fremont $($California$)$ Flyers roller derby team. The license allows the roller derby team to use the trademark for five years for a total of $$15,000.$

Under U$.$S$.$ GAAP, how much revenue would Mary recognize in year $1$ of the license?
