in addition , many of our redevelopment and 3-r projects include consolidating small shop space to accommodate construction of new junior anchor space . capital and financing activities our ability to obtain capital on satisfactory terms and to refinance borrowings as they mature is affected by the condition of the economy in general and by the financial strength of properties securing borrowings . throughout 2017 , we were able to maintain our strong balance sheet , financial flexibility and liquidity to fund future growth . we ended the year with approximately $ 398 million of combined cash and borrowing capacity on our unsecured revolving credit facility . in addition , as of december 31 , 2017 , we have approximately $ 82.4 million of debt maturities through december 31 , 2020. the amount that we may borrow under our unsecured revolving credit facility is limited by the value of the assets in our unencumbered asset pool . as of december 31 , 2017 , the value of the assets in our unencumbered asset pool was $ 1.4 billion . the investment grade credit ratings we have received provide us with access to the unsecured public bond market , which we may continue to use in the future to finance acquisition activity , repay maturing debt and fix interest rates . summary of critical accounting policies and estimates our significant accounting policies are more fully described in note 2 to the accompanying consolidated financial statements . as disclosed in note 2 , the preparation of financial statements in accordance with gaap requires management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes . actual results could differ from those estimates . we believe that the following discussion addresses our most critical accounting policies , which are those that are most important to the compilation of our financial condition and results of operations and require management 's most difficult , subjective , and complex judgments . valuation of investment properties management reviews operational and development projects , land parcels and intangible assets for impairment on at least a quarterly basis or whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable . the review for possible impairment requires management to make certain assumptions and estimates and requires significant judgment . impairment losses for investment properties and intangible assets are measured when the undiscounted cash flows 49 estimated to be generated by the investment properties during the expected holding period are less than the carrying amounts of those assets . impairment losses are recorded as the excess of the carrying value over the estimated fair value of the asset . our impairment review for land and development properties assumes we have the intent and the ability to complete the developments or projected uses for the land parcels . if we determine those plans will not be completed or our assumptions with respect to operating assets are not realized , an impairment loss may be appropriate . depreciation may be accelerated for a redevelopment project , including partial demolition of existing structures after the asset is assessed for impairment . operating properties will be classified as held for sale only when those properties are available for immediate sale in their present condition and for which management believes it is probable that a sale of the property will be completed within one year , among other factors . operating properties classified as held for sale are carried at the lower of cost or fair value less estimated costs to sell . depreciation and amortization are suspended during the held-for-sale period . our operating properties have operations and cash flows that can be clearly distinguished from the rest of our activities . historically , the operations reported in discontinued operations include those operating properties that were sold or were considered held for sale and for which operations and cash flows can be clearly distinguished . the operations from these properties are eliminated from ongoing operations , and we will not have a continuing involvement after disposition . in 2014 , we adopted the provisions of asu 2014-08 , presentation of financial statements ( topic 205 ) and property , plant , and equipment ( topic 360 ) : reporting discontinued operations and disclosures of disposals of components of an entity , which will result in fewer real estate sales being classified within discontinued operations , as only disposals representing a strategic shift in operations will be presented as discontinued operations . no properties that have been sold , or designated as held-for-sale , since the adoption of asu 2014-08 , have met the revised criteria for classification within discontinued operations . acquisition of real estate investments upon acquisition of real estate operating properties , we estimate the fair value of acquired identifiable tangible assets and identified intangible assets and liabilities , assumed debt , and any noncontrolling interest in the acquiree at the date of acquisition , based on evaluation of information and estimates available at that date . based on these estimates , we record the estimated fair value to the applicable assets and liabilities . in making estimates of fair values , a number of sources are utilized , including information obtained as a result of pre-acquisition due diligence , marketing and leasing activities . the estimates of fair value were determined to have primarily relied upon level 2 and level 3 inputs , as defined below . story_separator_special_tag the nareit white paper defines ffo as net income ( determined in accordance with gaap ) , excluding gains ( or 55 losses ) from sales and impairments of depreciated property , plus depreciation and amortization , and after adjustments for unconsolidated partnerships and joint ventures . considering the nature of our business as a real estate owner and operator , we believe that ffo is helpful to investors in measuring our operational performance because it excludes various items included in net income that do not relate to or are not indicative of our operating performance , such as gains or losses from sales of depreciated property and depreciation and amortization , which can make periodic and peer analyses of operating performance more difficult . for informational purposes , we have also provided ffo adjusted for accelerated amortization of debt issuance costs , transaction costs , a severance charge and a debt extinguishment loss in 2016. we believe this supplemental information provides a meaningful measure of our operating performance . we believe our presentation of ffo , as adjusted , provides investors with another financial measure that may facilitate comparison of operating performance between periods and among our peer companies . ffo should not be considered as an alternative to net income ( determined in accordance with gaap ) as an indicator of our financial performance , is not an alternative to cash flow from operating activities ( determined in accordance with gaap ) as a measure of our liquidity , and is not indicative of funds available to satisfy our cash needs , including our ability to make distributions . our computation of ffo may not be comparable to ffo reported by other reits that do not define the term in accordance with the current nareit definition or that interpret the current nareit definition differently than we do . our calculations of ffo 1 and reconciliation to consolidated net income and ffo , as adjusted for the years ended december 31 , 2017 , 2016 and 2015 ( unaudited ) are as follows : replace_table_token_24_th 1 “ ffo of the operating partnership `` measures 100 % of the operating performance of the operating partnership 's real estate properties . “ ffo attributable to kite realty group trust common shareholders ” reflects a reduction for the redeemable noncontrolling weighted average diluted interest in the operating partnership . earnings before interest , tax , depreciation , and amortization ( ebitda ) 56 we define ebitda , a non-gaap financial measure , as net income before depreciation and amortization , interest expense and income tax expense of taxable reit subsidiary . for informational purposes , we have also provided adjusted ebitda , which we define as ebitda less ( i ) ebitda from unconsolidated entities , ( ii ) gains on sales of operating properties or impairment charges , ( iii ) other income and expense , ( iv ) noncontrolling interest ebitda and ( v ) other non-recurring activity or items impacting comparability from period to period . annualized adjusted ebitda is adjusted ebitda for the most recent quarter multiplied by four . net debt to adjusted ebitda is our share of net debt divided by annualized adjusted ebitda . ebitda , adjusted ebitda , annualized adjusted ebitda and net debt to adjusted ebitda , as calculated by us , are not comparable to ebitda and ebitda-related measures reported by other reits that do not define ebitda and ebitda-related measures exactly as we do . ebitda , adjusted ebitda and annualized adjusted ebitda do not represent cash generated from operating activities in accordance with gaap , and should not be considered alternatives to net income as an indicator of performance or as alternatives to cash flows from operating activities as an indicator of liquidity . considering the nature of our business as a real estate owner and operator , we believe that ebitda , adjusted ebitda and the ratio of net debt to adjusted ebitda are helpful to investors in measuring our operational performance because they exclude various items included in net income that do not relate to or are not indicative of our operating performance , such as gains or losses from sales of depreciated property and depreciation and amortization , which can make periodic and peer analyses of operating performance more difficult . for informational purposes , we have also provided annualized adjusted ebitda , adjusted as described above . we believe this supplemental information provides a meaningful measure of our operating performance . we believe presenting ebitda and the related measures in this manner allows investors and other interested parties to form a more meaningful assessment of our operating results . the following table presents a reconciliation of our ebitda , adjusted ebitda and annualized adjusted ebitda to consolidated net income ( the most directly comparable gaap measure ) and a calculation of net debt to adjusted ebitda . replace_table_token_25_th 1 represents adjusted ebitda for the three months ended december 31 , 2017 ( as shown in the table above ) multiplied by four . 57 comparison of operating results for the years ended december 31 , 2017 and 2016 the following table reflects changes in the components of our consolidated statements of operations for the years ended december 31 , 2017 and 2016 : replace_table_token_26_th rental income ( including tenant reimbursements ) increased $ 1.9 million , or 0.6 % , due to the following : replace_table_token_27_th the net increase of $ 8.0 million in rental income for properties that were fully operational during 2016 and 2017 is primarily attributable to an increase in rental rates and an increase in occupancy , which leads to more tenants paying rent . the increase in rental revenue is primarily due to multiple anchor and small shop tenants opening as we completed or partially completed various redevelopment and repositioning projects including trader joe 's at centennial gateway , ross dress for less at trussville promenade , party city at market

cash provided by operating activities was $ 153.7 million for the year ended december 31 , 2017 , a decrease of $ 1.3 million from the same period of 2016 . the slight decrease was primarily due to a decrease in cash provided by operating activities due to our 2017 property sales , partially offset by the completion of several 3-r projects , and higher revenue on sales of undepreciated assets in 2017. cash used in investing activities was $ 0.1 million for the year ended december 31 , 2017 , as compared to cash used in investing activities of $ 82.7 million in the same period of 2016 . the major changes in cash used in investing activities are as follows : net proceeds of $ 76.1 million related to the sale of cove center , clay marketplace , the shops at village walk and wheatland towne crossing in 2017 , compared to net proceeds of $ 14.2 million from two property sales in 2016 ; and decrease in capital expenditures of $ 23.8 million , partially offset by a decrease in construction payables of $ 4.3 million . in 2017 , we incurred additional construction costs at our parkside towne commons - phase ii and holly springs towne center - phase ii development projects , and additional construction costs at several of our redevelopment properties . cash used in financing activities was $ 149.3 million for the year ended december 31 , 2017 , compared to cash used in financing activities of $ 86.3 million in the same period of 2016 .
