Cost Variance Analysis Presented by : Edmund C. Cabrera MBA Student Universidad de Manila Definitions STANDARD COSTS – are predetermined or target unit costs of production which should be attained under efficient conditions. It is the amount and costs of direct material‚ direct labor‚ and factory overhead required to produce one unit of finished product. STANDARD COST SYSTEM – is an accounting system which uses standard costs rather than actual costs to account for units as they flow through

our case study‚ we conclude that we need to do a variance analysis to better understand the plant performance compared to the previous year. The main problem in related to this case is about the falling in revenues‚ the performance of coal-plant‚ the price of coal and the quality of coal. All of this problem will be answered in the next sections in the qualitative analysis of Luotang Power.

Mean-Variance Analysis Mean-variance portfolio theory is based on the idea that the value of investment opportunities can be meaningfully measured in terms of mean return and variance of return. Markowitz called this approach to portfolio formation mean-variance analysis. Mean-variance analysis is based on the following assumptions: 1. All investors are risk averse; they prefer less risk to more for the same level of expected return. 2. Expected returns for all assets are known. 3. The
