periods presented in order to present all segment information on a comparable basis . there is no impact on our previously reported consolidated statements of income , balance sheets or statements of cash flows resulting from these segment changes . value drivers of our business in recent years , we have reshaped our portfolio of businesses to focus on high-growth , high-margin businesses , successfully integrated exelis and made investments that led to several new product launches and strategic program awards . fiscal 2018 marked an inflection point as we returned to growth across all three business segments , maintained strong margins through our focus on operational excellence and recorded significantly higher orders that drove a 26 percent increase in backlog for fiscal 2018 compared with fiscal 2017. in addition to dividends and share repurchases , we made debt repayments and voluntary pension plan contributions that expanded our future financial flexibility . we plan to build on our strong fiscal 2018 performance , and together with a well-funded u.s. government budget and a continued focus on operational excellence and innovation , we believe we are well positioned to achieve our fiscal 2019 strategic priorities , which include the following : accelerating revenue growth across all three business segments ; driving flawless execution while expanding margins through operational excellence ; and sustaining cash flow with shareholder friendly capital deployment . we expect a more favorable budget environment , especially in strategic areas , our solid fiscal 2018 backlog growth and strong customer relationships to serve as the basis for accelerating revenue growth across our business segments in fiscal 2019. the government fiscal year ( “ gfy ” ) 2018 omnibus appropriations bill reflected that our programs continue to remain a priority for u.s. government customers , and president trump 's gfy 2019 budget proposal would fully fund all of our major dod and civil agency programs . for communication systems , dod tactical modernization programs are beginning to increase across all the services , and we expect our international tactical business to be able to leverage its incumbent position and large installed base and benefit from higher defense spending by coalition partners . in electronic systems , we believe we are entering a multi-year growth cycle driven by our position on long-term avionics and electronic warfare platforms . for space and intelligence systems , we believe , in a growing budget environment , we will be able to maintain high win-rates and expand into adjacencies in order to accelerate growth in classified programs , and we expect our environmental business to stabilize and return to growth . we believe operational leverage from accelerating growth across our business segments , combined with our continued focus on operational excellence and innovation , will drive margin expansion and increased profitability . our operational excellence program , harris business excellence ( “ hbx ” ) , is focused on streamlining processes , eliminating waste , reducing costs , optimizing program execution and increasing customer satisfaction . we are approximately half-way through standardizing our it systems , which we expect will dramatically reduce the number of enterprise resource planning platforms , simplify our operating environment , drive productivity through growth in shared services , automate core processes and lay the foundation of our enterprise-wide digital strategy . we are working toward eliminating many of our data centers and making the remainder cloud-enabled . we also are continuing to focus on cost savings in our supply chain through “ value engineering ” and “ should-cost ” analysis , as well as improving supplier performance and reducing sole-sourced components on legacy solutions . innovation is at the core of our success , and r & d investment represents the foundation for innovation . we are fundamentally reshaping how we design and develop new products to get more out of our r & d investment . we are deploying “ devops ” to streamline software development , which has grown to be a significant portion of our engineering work today and is expected to increase over time . we also use standardized processes and common metrics to track progress and gauge success , as well as core technology centers to more fully leverage r & d investment across our company . during fiscal 2018 , we returned to our shareholders $ 272 million in dividends and another $ 272 million through share repurchases . we also used $ 271 million for net repayment of borrowings and $ 300 million for a voluntary contribution to our u.s. defined benefit plans , which helped reduce our net unfunded defined benefit plans liability by 44 percent to $ 0.7 billion or 11 percent of total liabilities at the end of fiscal 2018 . in fiscal 2019 , we believe accelerating revenue growth across our business segments , margin expansion and increased profitability will improve our operating cash flow , which we expect to use for increased dividends , share repurchases , debt repayments and reinvestment to grow our strategic businesses . story_separator_special_tag ” in fiscal 2016 , our effective tax rate benefited from : settlement of several items for
