[1] During the fourth quarter of 2015, Penn received a significant real estate tax refund related to a property reassessment of a GLPI owned property, which directly offset its real estate taxes paid during the quarter. Although tenants are responsible for the payment of real estate taxes under the triple-net lease structure, the Company is required to record revenue for the real estate taxes paid by its tenants on the leased properties with an offsetting expense in real estate taxes within the consolidated statement of income as the Company has concluded it is the primary obligor. This tax refund resulted in the lower net revenues in the fourth quarter of 2015, as compared to the fourth quarter of 2014, despite an increase in rent recognized from tenant lease payments but had no impact on income from operations or net income.
