PSA 401: Auditing in a Computer Information Systems Environment

- The increasing availability of computer-based accounting systems that is capable of meeting both functional and economic circumstances of even the smallest entity impacts on the audits of those entities. Small entities’ accounting systems often make use of personal computers. Philippine Auditing Practice Statement 1001, “CIS Environments—Stand-Alone Personal Computers” gives additional guidance regarding the special considerations of such an environment.
- Small entities are likely to use less sophisticated hardware and software packages than large entities (often “packaged” rather than developed “in house”). Nevertheless, the auditor has sufficient knowledge of the computer information system to plan, direct, supervise, and review the work performed. The auditor may consider whether specialized skills are needed in an audit.
- Because of the limited segregation of duties, the use of computer facilities by a small entity may have the effect of increasing control risk. For example, it is common for users to be able to perform two or more of the following functions in the accounting system.
• Initiating and authorizing source documents.
• Entering data into the system.
• Operating the computer.
• Changing programs and data files.
• Using or distributing output.
• Modifying the operating systems.
- The use of computer information systems by small entities may assist the auditor in obtaining assurance as to the accuracy and appropriateness of accounting records by reducing control risk. Computerized information systems may be better organized, less dependent upon the skills of people using them, and less susceptible to manipulation than non-computerized systems. The ability of the auditor to obtain relevant…...

Waukegan's Superfund Sites

...a ballasted foundation, a foundation that sits atop of the soil and does not disturb remediation efforts, all the while creating a sustainable use out of a once environmental disaster area. The main owners of this site are the Waukegan School District and the Waukegan Park District. These are both Districts of the city that would greatly benefit for the potential revenue stream. After a thorough assessment of the site it has been determined that 45 acres of the site can be utilized for solar power. Through this same assessment it was determined that the site has an irradiance level of 4.25kWh/m2/day. The proposed solar site is also in a prime location with Common Wealth Edison’s high voltage power lines running through the site and a ComEd substation approximately 500 feet west of the site. The potential cost of the project is as shown below. There is a potential for serious project cost savings through Illinois Financing Incentives as well as a $2.50/W savings up to 30% of the project cost through the Solar & Wind Rebate and a $2.60/W savings up to 40% of the project cost not to exceed $250,000 provided by the Community Solar & Wind Grant. This grants and rebates are generally a multi-year incentive which make a solar project off this magnitude financial feasible. There have been 3 owner options that have been proposed. The first option being a land lease, this option has the least risk to the Waukegan Districts that own it but also the least pay out. The second......

...the environment and ensuring that pollutants are kept to a minimum and an effort to prevent monopolies. Looking toward the future, we expect to see an increase in the expenses for utility companies as more regulations are added, but also expect to see growth in the industry as power reaches more areas of the globe. “The Energy Information Administration projects that 355 gigawatts of new electric generating capacity - or more than 40% more than the industry currently supplies - will be needed by 2020 to meet growing demand.” Two companies that fit our expectations in the utility industry are The Southern Company (NYSE:SO) and Exelon Corporation (EXC). Exelon is a utility holding company that has more well-known subsidiaries such as ComEd and PECO Energy Company. Through its subsidiaries, Exelon does business in the generation of electricity as well as selling electricity to consumers. Southern Company is also a holding company that owns public utility companies in Florida, Alabama, Georgia, and Mississippi. Exelon has a larger market to work with then Southern company as it services all across the United States. One of the key issues identified in this industry were growing regulations and environmental issues.

...(diachronic) linguistics.   The role of analogy Analogy has been mentioned in connection with its inhibition of the regular operation of sound laws in particular word forms. This was how the Neogrammarians thought of it. In the course of the 20th century, however, it has come to be recognized that analogy, taken in its most general sense, plays a far more important role in the development of languages than simply that of sporadically preventing what would otherwise be a completely regular transformation of the sound system of a language. When a child learns to speak he tends to regularize the anomalous, or irregular, forms by analogy with the more regular and productive patterns of formation in the language; e.g., he will tend to say “comed” rather than “came,” “dived” rather than “dove,” and so on, just as he will say “talked,” “loved,” and so forth. The fact that the child does this is evidence that he has learned or is learning the regularities or rules of his language. He will go on to “unlearn” some of the analogical forms and substitute for them the anomalous forms current in the speech of the previous generation. But in some cases, he will keep a “new” analogical form (e.g., “dived” rather than “dove”), and this may then become the recognized and accepted form.   Other 19th-century theories and development Inner and outer form One of the most original, if not one of the most immediately influential, linguists of the 19th century was the learned Prussian......

Exelon is the largest nuclear operator in the U.S. and the 4th largest power generator (in GW) of the nation. Question & Answers Question 1: How will branding benefit Exelon power? Answer: Exelon’s plan to brand Environmentally Preferable Power (EPP) serves 2 goals: * Charge a Premium for EPP and get better margins for a superior product. * To gain incremental business outside of its traditional served markets. Branding will send a strong signal to the market. Exelon is the 1st company attempting to market an ISO certified energy in the industry. Being the 1st mover not only gives Exelon the opportunity to shape the market but also to position Eco Preferred as a premium Product. The value of Eco Preferred comes from the fact that it is going to be a differentiating tool for companies purchasing it. Companies are used to purchasing electricity as a commodity & focusing only on price. Brand could help address this problem by giving a name and an identity to their......

El Sagrario

...cuerpo de Cristo, él se queda con nosotros como compañero y amigo, ya que al hacer el milagro de la Consagración Él no puso límite de tiempo, simplemente dijo: “este es mi cuerpo”. El pan y el vino se encuentran dentro del Sagrario. La Eucaristía nos enseña que Jesús está en el Santísimo Sacramento del altar con su cuerpo, alma, sangre y Divinidad. Después de la consagración del pan y del vino, nuestro Señor Jesucristo, verdadero Dios y verdadero hombre, está contenido verdaderamente, realmente y substancialmente bajo la especie de aquellas cosas sencillas. En la procesión del Corpus Christi, como hemos dicho, acompañamos al Resucitado en su camino por el mundo entero. Precisamente al hacer esto respondemos también a su mandato: "Tomad, comed... Bebed de ella todos" (Mt 26, 26 s). La finalidad de esta comunión, de este comer, es la asimilación de mi vida a la suya, mi transformación y configuración con Aquel que es amor vivo. Por eso, esta comunión implica la adoración, implica la voluntad de seguir a Cristo, de seguir a Aquel que va delante de nosotros. La noche antes de que Jesús fuera a morir en la cruz, se reunió con sus 12 apóstoles a cenar, y ahí convirtió el pan en su Cuerpo y el vino en su Sangre, para poder quedarse siempre con nosotros, y les dijo a sus apóstoles: "Hagan esto en memoria mía. Desde entonces en todas las misas, el momento principal es el de la consagración, que es cuando el pan y el vino se convierten en el cuerpo y la sangre de Jesús, que es......

Greening the Supply Chain at Danaher the pending legislation in Congress, the United States Environmental Agency has published a document called the “Lean and Green Supply Chain” stressing the importance of companies to develop a new leaner and greener supply chain. It highlights four key steps that take place in the decision making framework of developing a green supply chain. These include: identifying costs, determining opportunities, calculating benefits, and implementing the policies. The document clearly shows the value of companies looking long term at their environmental initiatives as a means to increase their sustainability. It specifically references an example of Comed; a company who shares similarities to Danaher with respect to the financial and environmental burden related the disposal of its chemical solvents and PC boards. The document highlights how Comed was able to achieve a cost savings of $1,000,000 and reduce their hazardous solvent waster by 85% by implementing the EPA “green supply chain” decision making framework. It is apparent that companies like Danaher are moving towards sustainable, green supply chains. Sustainability can be a competitive advantage for many companies. If they can develop a sustainable supply chain, great cost savings can be achieved by not having to dispose of harmful by-products, reducing obsolescence, decreasing the amount of money spent on scrap and the resources spent on adhering to regulatory issues. Recommendations: 1) Develop a “Green Task......
