The Green Company, an accrual basis taxpayer, provides business-consulting services. Clients generally pay a retainer at the beginning of a 12-month period. This entitles the client to no more than 40 hours of services. Once the client has received 40 hours of services, Green charges $400 per hour. Green Company allocates the retainer to income based on the number of hours worked on the contract. At the end of the tax year, the company had $40,000 of unearned revenues from these contracts. The company also had $10,000 in unearned rent income received from excess office space leased to other companies. Based on the above, how much does Green need to include in gross income for the current year?
