2018 summary of operations during 2018 , we achieved domestic system-wide same-stores sales growth of 0.8 % , comprised of a 1.8 % increase at company restaurants and a 0.6 % increase at domestic franchised restaurants , marking the eighth consecutive year of positive system-wide same-store sales . a total of 203 remodels were completed during 2018 , comprised of 193 at franchised restaurants and ten at company restaurants . these remodels were in our heritage image , which we launched in late 2013. this updated look reflects a more contemporary diner feel to further reinforce our america 's diner positioning . by the end of 2019 , we expect approximately 90 % of the system will have been remodeled to the most current image . our current franchise agreement includes a royalty rate of up to 4.5 % . approximately 50 % of our franchised restaurants were operating under this agreement as of december 26 , 2018 , and we expect approximately 60 % to be operating under this agreement by the end of 2019. we anticipate that existing franchisees will elect to migrate to the new fee structure over the next decade as incentives under previous franchise agreements expire . due to the long-term migration of existing franchisees , we will not see the full benefit of the higher royalty rate for some time . for 2018 , our average domestic royalty rate was approximately 4.17 % , compared to 4.14 % for 2017 and 4.11 % for 2016 . 20 growing the brand over the last five years our growth initiatives have led to 202 new restaurant openings . during 2018 , we opened 30 restaurants including nine international franchised locations with three in canada , two in the philippines and one each in honduras , mexico , puerto rico and the united kingdom . our goal is to increase net restaurant growth through both domestic and international avenues . domestic growth will focus on markets in which we have modest penetration . development agreements related to the sale of 90 to 125 of our company operated restaurants and recently announced enhanced development agreements in canada and the philippines are expected to stimulate domestic and international growth over the next several years . balancing the use of cash we are focused on balancing the use of cash between reinvesting in our base of company restaurants , growing and strengthening the brand and returning cash to shareholders . during 2018 , cash capital expenditures were $ 32.4 million , comprised of $ 22.0 million in capital expenditures and restaurant and real estate acquisition costs of $ 10.4 million . cash flows for acquisitions included $ 8.1 million for the reacquisition of six franchised restaurants , $ 1.8 million for real estate and $ 0.5 million related to a prior year acquisition . in november 2018 , as part of our previously authorized share repurchase programs , we entered into a variable term , capped accelerated share repurchase ( the “ asr ” ) agreement with mufg securities emea plc ( “ mufg ” ) to repurchase an aggregate of $ 25 million of our common stock . pursuant to the terms of the asr agreement , we paid $ 25 million in cash , received approximately 1.1 million shares of our common stock ( which represents the minimum shares to be delivered based on the cap price ) and recorded $ 18.2 million of treasury stock related to these shares . the remaining balance of $ 6.8 million is included as additional paid-in capital in shareholders ' equity as of december 26 , 2018 as an equity forward contract . the total aggregate number of shares of our common stock repurchased pursuant to the asr agreement will be based generally on the average of the daily volume-weighted average prices of our common stock , less a fixed discount , over the term of the asr agreement , subject to a minimum number of shares . during 2018 , including shares repurchased under the asr , we repurchased a total of 3.9 million shares of our common stock for $ 61.2 million . since initiating our share repurchase programs in november 2010 , we have repurchased a total of 47.1 million shares of our common stock for $ 416.8 million . as of december 26 , 2018 , there was $ 128.4 million remaining under the current repurchase program . factors impacting comparability transition to new revenue recognition accounting standard effective december 28 , 2017 , the first day of fiscal 2018 , we adopted accounting standards update 2014-09 , “ revenue from contracts with customers ( topic 606 ) , ” and all subsequent asus that modified topic 606 on a modified retrospective basis . results for reporting periods beginning after december 28 , 2017 are presented under topic 606. prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting under topic 605 “ revenue recognition . ” the adoption of topic 606 did not impact the recognition of company restaurant sales or royalties from franchised restaurants . the most significant effects of the new guidance on the comparability of our results of operations between 2018 , 2017 and 2016 include the following : under topic 606 , advertising revenues and expenditures are recorded on a gross basis within the consolidated statements of income . under the previous guidance of topic 605 , we recorded franchise advertising expense net of contributions from franchisees to our advertising programs , including local co-operatives . while this change materially impacts the gross amount of reported franchise and license revenue and costs of franchise and license revenue , the impact is generally an offsetting increase to both revenue and expense with little , if any , impact on operating income and net income . story_separator_special_tag the following table presents
