This note reviews the basics of projecting cash flows for a typical operating decision. \u0000 \u0000The focus on cash flows arises because any evaluation of economic impact must recognize opportunity costs—the other uses to which one might allocate resources available to a firm. Since a cash flow received today can be invested, it matters whether a decision generates a cash flow today versus a cash flow in the future. The central challenge with cash flow projections, therefore, is to adjust correctly for items that affect the timing of cash flows: accrual accounting impacts on reported results and tax effects associated with depreciation and amortization. \u0000 \u0000There are two typical ways to organize operating information to calculate cash flow. The first estimates the cash consequences related to various elements of a decision. We will refer to this approach as a calculation of cash flow by parts. The second starts with a typical accounting estimate of operating income before taxes and then makes adjustments. We will refer to this approach as a calculation of free cash flow. In either situation, the resulting cash flow can be referred to as \"free cash flow,\" though this name is more commonly associated with the second approach. \u0000 \u0000. . .","PeriodicalId":121773,"journal":{"name":"Darden Case: Business Communications (Topic)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126450120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All products are plant-based foods distributed nationally in the United States. Seeking to target mainstream tastes and low price, tensions among the three pillars of the brand's marketing strategy, which are quality, accessibility, and sustainability, leave the case open to explore uncertainty, positioning, marketing mix, and consumer behavior. The A case opens with Josh Tetrick, Just's founder and CEO, facing an obstacle to the brand around accessibility. Target delisted all Just products in its stores after receiving an unverified, anonymous letter claiming that some of the products were unsafe and mislabeled. Although it only accounted for a small percentage of sales, losing Target affected Just's ability to meet its distribution goal to reach price-conscious consumers where they shopped and its greater goal to build a food system where everyone could eat well. \u0000Excerpt \u0000UVA-M-0956 \u0000Rev. Aug. 20, 2019 \u0000Just: Positioned to Target Mainstream Tastes? (A) \u0000Just CEO Josh Tetrick founded his food innovation start-up in San Francisco in 2011. Six years later, he was running the multi-million-dollar company based on “things he knew to be true.” The truth that had set Tetrick in motion was that the the arconventional food system left billions of people eating poorly or not at all. Another truth that guided Just was that many mainstream consumers rejected veganism, which ran counter to their identities. As such, Tetrick and his team were dead set on positioning the Just brand in such a way that it would appeal to mainstream consumers—not because Just products happened to be plant based or because they aimed to cause no unnecessary harm to the planet or to animals—but because Just products were high quality, accessible, and affordable. Indeed, the three pillars of the brand's marketing strategy were quality, accessibility, and sustainability. Just's mantra was that humankind had a system problem, not a people problem: it was too easy for mainstream consumers to do the wrong thing. In Tetrick's estimation, “The only way the good thing wins is when the good thing is so radically better than the not-so-good thing that you cannot help but do it. If it's not affordable and delicious, it's completely irrelevant to solving the problem.” \u0000. . .","PeriodicalId":121773,"journal":{"name":"Darden Case: Business Communications (Topic)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127996789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
