Document 14: MLS rivalry cups: In Major League Soccer, several teams annually compete for secondary rivalry cups that are usually contested by only two teams, with the only exception being the Cascadia Cup, which is contested by three teams. Each cup or trophy is awarded to the eligible team with the better regular season record and are comparable to minor trophies played for in college football rivalries. Most cups are deliberately conceived as local derbies between teams in the same region. Rivalry cups are considered a tradition to most MLS fans and players alike. Out of the ten original MLS teams only three have not competed in these rivalry cups: Sporting K.C., New England Revolution and the defunct Tampa Bay Mutiny. Most newer local derbies such as the 401 Derby and Hudson River Derby are not contested for rivalry cups but instead for bragging rights of rival supporters groups. The only rivalry between two original MLS clubs that do not compete for a cup is the San Jose Earthquakes and the LA Galaxy in the yearly edition of the California Clasico. The Texas Derby are the only MLS cup rivalry games where the winner does not walk away with a cup trophy. Instead, the winner takes home "El Capitán" a replica 18th century mountain howitzer cannon.
Document 15: Brau und Brunnen: Brau und Brunnen AG ("Brew and Spring") was a German brewing and beverage group which was formed as "Dortmunder Union-Schultheiss Brauerei AG" in 1972 through a merger between Schultheiss-Brauerei and Dortmunder Union-Brauerei. It was renamed "Brau und Brunnen" in 1988. It owned a number of formerly independent breweries, including Einbecker Brewery. Until the early 1990s, Brau und Brunnen was the largest beverage company in Germany, but its market share steadily declined throughout the 1990s. An additional cause for the decline was the company's purchase of Bavaria – St. Pauli Brewery and Jever for an estimated 800 million DM, although these purchases were later estimated to only be worth closer to 250 million DM. Other companies engaged in a series of mergers and acquisitions, and by 1999, it had sank to the fourth-largest beverage company and was continually losing money. After unsuccessful internal reorganizations, the company was purchased by Dr. August Oetker KG and integrated into its subsidiary Radeberger Gruppe.
