Reebok & LA Gear Analysis of two very different companies 1. Looking at both companies Return on Equity is pretty comparable between the two in 1990. However‚ we can see that LA Gear had a much better performance in the previous two years with a precipitous RoE in 1990 as compared to the previous two years. Reebok on the other had has reported a stable RoE in the last three years. Looking at the component ratios of RoE we can see some some differences why LA Gear has had a huge drop on RoE

Background: Cumberland Metal Industries (CMI) was one of the largest manufacturers of curled metal products in the country.Their sales grew from $250‚000 in 1963 to over 18‚500‚000 by 1979.It originally custom fabricated components for chemical process filtration and other highly technical applications. The company’s philosophy soon evolved from selling the metal as a finished product to selling products that used it as a raw material . Earlier CMI used to sell exaust gas recirculation(EGR) valves

Does the way people look really matter?! The way you look says a lot about the person you are inside and says more about your luck with others. Whether you support this idea or refute it‚ it has always been a topic of controversy. If you go out in the street‚ for example‚ and ask that question to as many people as you can‚ you’ll get tons of answers‚ depending on the point of view of the person you are addressing. But what people don’t get is that whatever their point of view is‚ they‚ most of

The Metal Injection Moulding process (MIM)‚ considered as a development of the Powder Injection Moulding (PIM)‚ became‚ over the years‚ a competitive manufacturing process for small components‚ offering an alternative to other processes‚ more expensive to create these parts. History of the technology The PIM process was at first developed in the 1930s in the USA. This process was originally intended for ceramics. Then‚ during the Second World War‚ metal powders appeared.

In the experiment‚ synthesis of copper compounds‚ the purpose was to recover the original amount of copper after series of chemical reactions. Then returning the copper back to its original form. The copper wire originally weighted 1.0099 g‚ but after the copper was transformed into Cu(OH)2 to CuO to CuSO4 and finally into Cu‚ the mass of the recovered copper was 1.1023g; the percent yield was 109%. Since the percent yield is more than 100%‚ an error must have occurred somewhere in the lab. A possible
