Under Armour: Repositioning for the Global Stage

Over the last two decades, Under Armour has emerged from being the “underdog” in the Sports Apparel and Sporting Goods Industry to a leader in the industry, with a fierce attention to performance and great skill at picking up-and-coming athletes who emerge as superstars. This case underscores its administrative heritage, competitive strategy and growth potential as a global player in a highly competitive industry. It addresses the tension between being a performance brand while launching lines for women versus technology applications and conflicts between its growth strategy and macroeconomic forces. It highlights areas in which Under Armour has succeeded in macroeconomic forces and where it may be vulnerable. Research Methodology: The research relies primarily on secondary sources and countless studies of Under Armour and its major competitors. Primary research is based on databases, videos of Under Armour’s Chief Executive Officer, Kevin Plank, and articles from Bloomberg to the Baltimore Sun (UA’s headquarters) on the history, growth and future of Under Armour. It also includes observations and site visits to one of its signature brand house stores

Orthomagmatic quartz and post-magmatic carbonate veins in a reported porphyry copper deposit, Andean Intrusive Suite, Livingston Island, South Shetland Islands

A previously reported porphyry Cu + Mo deposit in an Eocene pluton within the South Shetland Island magmatic arc has been re-interpreted as three distinct hydrothermal assemblages. The oldest assemblage (1) exsolved under confinement from the deep (∼6 km?) cooling magma whereas assemblages (2) and (3) formed during tectonic ± magmatic episodes at depths of < 1.5 km in the late Cenozoic. The three assemblages occur over the 5 × 11 km mapped in Barnard Point tonalite pluton. Assemblage (1) comprises shallowly dipping sheets of aplite, biotite + tourmaline pegmatite, massive ‘grey’ quartz, and quartz + tourmaline + bornite + chalcopyrite + molybdenite veins. Magnetite + tourmaline + chalcopyrite breccias have associated biotite, K-feldspar and muscovite alteration. Fluid inclusions indicate formation from hot (∼600°C), saline (40 equivalent weight % NaCl + CaCl2) aqueous-carbonic fluids that exsolved from the partly consolidated magma. The primary control on solution chemistry and nature of fracturing was the depth of pluton emplacement. Assemblage (2) consists of steep, vuggy veins and country-rock breccias, with thick propylitic alteration selvages, cemented by microcrystalline quartz, complex inter-growths of FeMg carbonate, bladed barite and trace amounts of bornite and chalcopyrite. These rocks, previously described as breccia (sensu ‘pebble’) dykes in the porphyry complex, are reinterpreted as an influx of moderately hot (175–330°C), weak to moderately saline (2–21 EWP NaCl), aqueous-carbonic fluids that underwent isobaric boiling at 0.8 to 1.3 km depth. Assemblage (3) consists of thin, hematitic fault infillings formed during a second episode of brittle faultin
