liquidity and capital resources our principal sources of funds to meet operating and capital expenses and debt service obligations and to pay distributions on our common shares are the operating cash flows we generate as rental income from our leased properties , residents fees and services revenues from our managed communities and borrowings under our revolving credit facility . we believe that these sources will be sufficient to meet our operating and capital expenses and debt service obligations and pay distributions on our common shares for the next 12 months and for the foreseeable future thereafter . our future cash flows from operating activities will depend primarily upon : our ability to maintain or increase the occupancy of , and the rental rates at , our properties ; our ability to control operating expenses at our properties ; our manager 's ability to operate our managed senior living communities so as to maintain or increase our returns ; and 87 our ability to purchase additional properties which produce cash flows in excess of our cost of acquisition capital and the related property operating expenses . our operating liquidity and resources we generally receive minimum rents monthly or quarterly from certain of our tenants , we receive percentage rents from our senior living community tenants monthly , quarterly or annually and we receive residents fees and services revenues , net of expenses , from our managed senior living communities monthly . our changes in cash flows for the year ended december 31 , 2017 compared to the year ended december 31 , 2016 were as follows : ( 1 ) cash provided by operating activities decreased to $ 407.1 million in 2017 from $ 426.8 million in 2016 ; ( 2 ) cash used for investing activities decreased to $ 221.4 million in 2017 from $ 292.9 million in 2016 ; and ( 3 ) cash used for financing activities increased to $ 186.1 million in 2017 from $ 139.8 million in 2016 .
