We receive a management fee based upon a percentage of revenues. Management fee revenues were $506,000, $518,000 and $540,000 for the years ended December 31, 2017, 2016 and 2015, respectively. We allocate certain operating expenses to PS related to the management of these properties, including payroll and other business expenses, totaling $537,000, $554,000 and $613,000 for the years ended December 31, 2017, 2016 and 2015, respectively. These amounts are included in “interest and other income” on our consolidated statements of income. The PS Business Parks name and logo are owned by PS and licensed to us under a non-exclusive, royalty-free license agreement. The license can be terminated by either party for any reason with six months written notice. PS provides us property management services for the self-storage component of two assets we own and operates them under the “Public Storage” name. Either the Company or PS can cancel the property management contract upon 60 days’ notice. Under our supervision, PS coordinates and assists in rental and marketing activities, property maintenance and other operational activities, including the selection of vendors, suppliers, employees and independent contractors. Management fee expenses were $92,000, $86,000 and $79,000 for the years ended December 31, 2017, 2016 and 2015, respectively. Additionally, PS allocated certain operating expenses to us related to the management of these properties totaling $61,000 for each of the three years ended December 31, 2017, 2016 and 2015. These amounts are included under “cost of operations” on our consolidated statements of income. Pursuant to a cost sharing and administrative services agreement, we share certain administrative services, corporate office space and certain other third party costs with PS which are allocated based upon time, effort and other methodologies. We reimbursed PS $1.3 million, $1.1 million and $1.2 million, respectively, in the years ended December 31, 2017, 2016 and 2015 for costs paid on our behalf, and PS reimbursed us $31,000 and $38,000 costs we incurred on their behalf for the years ended December 31, 2017 and 2016, respectively.
