Table of Contents material adverse effect on our business and financial results. See risk factors below under “Risks Specific to the Canadian Segment” for additional risks specific to competition in the Canadian beer market. Competition in our markets could require us to reduce prices or increase capital and other expenditures or cause us to lose sales volume, any of which could have a material adverse effect on our business and financial results. In many of our markets, our primary competitors have greater financial, marketing, production and distribution resources than we do, and may be more diverse in terms of their geographies and brand portfolios. In all of the markets in which we operate, aggressive marketing strategies, such as reduced pricing, brand positioning, and increased capital or other investments by these competitors could have a material adverse effect on our business and financial results. In addition, continuing consolidation among major global brewers and between brewers and other beverage companies may lead to stronger or new competitors, loss of partner brands, negative impacts on our distributor networks and pressures from marketing and pricing tactics by competitors. Further, consolidation of distributors in our industry could reduce our ability to promote our brands in the market in a manner that enhances rather than diminishes their value, as well as reduce our ability to manage our pricing effectively. Additionally, due to competition with brewers and other beverage companies, an increase in the purchasing power of our large competitors may cause further pricing pressures which could prevent us from increasing prices to recover higher costs necessary to compete. Such pressures could have a material adverse impact on our business and our financial results and market share. Failure to generate significant cost savings and margin improvement through our ongoing initiatives could adversely affect our profitability. Increased pressures for reduced pricing or difficulties in increasing prices while remaining competitive within our markets, as well as the need for increased capital investment, marketing and other expenditures could result in lower margins or loss of market share and volumes. Moreover, most of our major markets are mature, so growth opportunities may be more limited to us than to our competitors. For example, sales in the U.S. and Canada accounted for approximately 80% of our total 2018 sales. Our success as an enterprise depends largely on the success of relatively few products in several mature markets specific to the beer industry; if consumer preferences shift away from our products or consumption of our products decline, our business and financial results could be materially adversely affected. Our  Coors Light  and  Miller Lite  brands in the U.S.,  Coors Light, Molson Canadian , Coors Banquet  and  Carling  brands in Canada, and  Carling, Staropramen, Jelen, Bergenbier and  Coors Light  brands in Europe represented approximately half of each respective segment's sales volumes in 2018. Additionally, several of our brands represent a significant share of their respective market, therefore volatility in these markets could disproportionately impact the performance of these brands. Consequently, any material shift in consumer preferences away from these brands, or from the categories in which they compete, could have a material adverse effect on our business and financial results. Consumer preferences and tastes may shift away from our brands or beer generally due to, among others, changing taste preferences, demographics, downturn in economic conditions or perceived value, as well as changes in consumers' perception of our brands due to negative publicity, regulatory actions or litigation. Recently, there has been more attention focused on health concerns and the harmful effects of alcoholic beverages which could result in a change in the social acceptability of beer and other alcoholic beverages which could materially impact the consumption of beer and our sales. Additionally, in some of our major markets, specifically Canada, the U.S. and Europe, there has been a shift in consumer preferences within the total beer market away from premium brands to "craft beer" produced by smaller, regional microbreweries, as well as a shift within the total alcohol beverage market from beer to wine and spirits. Moreover, several of our major markets are mature and we have a significant share in such markets, therefore, small movements in consumer preference, such as consumer shifts away from premium light brands, can disproportionately impact our results. Although the ultimate impact is currently unknown, the emergence of legal cannabis in certain U.S. states and Canada may result in a shift of discretionary income away from our products or a change in consumer preferences away from beer. As a result, a shift in consumer preferences away from our products or beer or a decline in the consumption of our products could result in a material adverse effect on our business and financial results. The success of our business relies heavily on brand image, reputation, product quality and protection of intellectual property. It is important that we maintain and increase the image and reputation of our existing brands and products. Concerns about product quality, even when unsubstantiated, could be harmful to our image and reputation of our brands and products. While we have quality control programs in place, in the event we experienced an issue with product quality, we may experience recalls or liability in addition to business disruption which could further negatively impact brand image and reputation and negatively affect our sales. Our brand image and reputation may also be more difficult to protect due to less oversight and control as a result of the outsourcing of some of our operations. We also could be exposed to lawsuits relating to product liability or marketing or sales practices. Deterioration to our brand equity may be difficult to combat or reverse and could have a material effect on our business and financial results. In addition, because our brands carry family names, personal activities by certain members of the Molson or Coors families that harm their public image or reputation could have an adverse effect on our brands. Further, our success is dependent on our ability to protect our intellectual property rights, including trademarks, patents, domain names, trade secrets and know-how. We cannot be certain that the steps we have taken to protect 21
