Commitments and Contingencies Tenant Concentration Brookfield DTLA generally does not require collateral or other security from its tenants, other than security deposits or letters of credit. Our credit risk is mitigated by the high quality of our existing tenant base, review of prospective tenants risk profiles prior to lease execution, and frequent monitoring of our tenant portfolio to identify problem tenants. However, since we have a significant concentration of rental revenue from certain tenants, the inability of those tenants to make their lease payments could have a material adverse effect on our results of operations, cash flow or financial condition. A significant portion of Brookfield DTLAs rental income and tenant reimbursements revenue is generated by a small number of tenants. During the year ended December 31, 2013 , one tenant, The Capital Group Companies, accounted for more than 10% of our consolidated and combined rental income and tenant reimbursements revenue. No tenant accounted for more than 10% of our consolidated rental income and tenant reimbursements revenue during the years ended December 31, 2015 and 2014 . During the year ended December 31, 2013 , BOA Plaza and EY Plaza each contributed more than 10% of Brookfield DTLAs consolidated and combined revenue. The revenue generated by these two properties totaled 72% of Brookfield DTLAs consolidated and combined revenue during the year ended December 31, 2013 . During the years ended December 31, 2015 and 2014 , EY Plaza, BOA Plaza, Wells Fargo CenterNorth Tower, Wells Fargo CenterSouth Tower, Gas Company Tower and 777 Tower each contributed more than 10% of Brookfield DTLAs consolidated revenue. The revenue generated by these six properties totaled 98% and 100% of Brookfield DTLAs consolidated revenue during the years ended December 31, 2015 and 2014 , respectively.
