...submits that it is not the case of Revenue that the sales to the government are not normal or genuine transactions. It is also not suggested, he says, that the price at which the goods are sold to the government is not the normal price in the course of wholesale trade. In such a situation, the most convenient - convenient form the point of view of the Revenue as well as the assessee - course would be to treat the price at which the goods are sold to the government as the normal price within the meaning of Section 4(1)(a). In fact, the learned Counsel says, that should be the only method. However, if for some reason, the Revenue is not prepared to adopt this course then, he says, the Revenue has to deduct all the aforesaid expenses and not merely the transportation charges as specifically provided by Sub-section (2) of Section 4. Sri Nariman relies upon the holding in Bombay Tyre International that deductions other than those specifically mentioned in Section 4 are permissible in law, depending no doubt upon the character of the deduction claimed. On the other hand, Sri Chandrasekheran, learned Additional Solicitor General, submits that Sub-section (2) of Section 4 does specifically envisage and provide for the situation concerned herein. It provides expressly that where the price of any excisable goods is not known at the place of removal and the value of such goods is determined with reference to the price charged at the time of their delivery from a place other than the place...

...WORK LIFE TIME MANAGEMENT POST TRAINING ASSIGNMENT 1. What are the areas of learning that you acquired from the training? 2. Provide some recommendations on how you can apply the learning to your workplace. Elaborate. The area of learning that I acquired from the training is Pareto Principle – “80% percent of the value comes from 20% of the items.” Of the things we do during the day, only 20% really matters, therefore at work, I should prioritize the main items to be done everyday and avoid wasting time on the 80% that are not important. For example, fillings of unimportant documents do not need to be done straight away. It can be done during tea break and utilized the normal working time to complete other more important tasks. Another area of learning from the training is Murphy’s law – “If things can go wrong, they will go wrong.” There are areas that are beyond our control therefore for any occasion, we would need to perceive that there will be uncertainty in life and estimate more time for completion. For example, when work assigned need to be completed within the day, I should complete as much as I can in the morning because there might be disruptions during the day or new assignment that is urgent to be completed first but still cannot delay the proposed tasks. The last area of learning is to understand on task values. One should aim to schedule 60% of your time for proactive tasks, leaving the other 40% for reactive and maintenance tasks. One should...

...time were recorded by the department. Under the direct supervision of Engr. Aisporna are 10 supervisors who are graduates of engineering courses and with an average of three years work experience. Ten workers report to a supervisor. All of the workers are high school graduates. All employees including the supervisors and the workers are paid on a monthly basis. The workers, however, are required to produce a minimum number of units per day. During the slack seasons, workers are engaged only from 50% to 75% of their normal working hours due to lack of sufficient job orders. No worker is laid off by the company and everyone receives full pay. This is so because of the strong recommendation made by Engr. Aisporna to the top management. Slack seasons last up to three months. At the fourth month, job orders begin to pour in and everybody starts to cover 100% of their working time. On the seventh month of the current year, orders were received at more than the normal capacity of the company. For the first time since the company began operating, the department will be required to work...

...manufacturing environment, firms adopt various quality improvement programs to reduce spoilage, rework units, and scrap: • Spoilage refers to unacceptable units (i.e., do not meet the specifications required by customers for good units) that are discarded or sold for disposal value (or sold at reduced prices).1 • Rework units are units produced that must be reworked into good units that can be sold in regular channels. • Scrap is the material left over from the manufacture of the product (i.e., residual materials); it has little or no value. The two types of spoilage are normal and abnormal. Normal spoilage occurs under normal operating conditions; it is uncontrollable in the short term and is considered a normal part of production and product cost. That is, the cost of normal spoilage unit is absorbed by the cost of good units produced. Abnormal spoilage is in excess over the amount of normal spoilage expected under normal operating conditions; it is charged as a loss to operations in the period detected. Example 1: In October 2005, Mendonza Co. incurs costs of $615,000 to produce 20,500 units. Of these 20,500 units, 20,000 are good units and 500 are spoiled units. Mendonza has no beginning inventory and no ending inventory that month. Of the 500 spoiled units, 400 units are spoiled because the injection molding machines are unable to manufacture good casing 100% of the time. That is, these units are spoiled even though the machines were run carefully and efficiently. The remaining 100...

...Table 2.8 contains data for the installation of new equipment in a manufacturing process at your customer’s plant. Your company is responsible for the project. Indirect costs are $10,000 per week, and a penalty cost of $10,000 per week will be incurred for every week the projects is delayed beyond week 9. 1. What is the shortest time duration for the project regardless of cost? 2. What is the minimum total cost associated with completing the project in 12 weeks? 3. What is total time of the minimum-cost schedule? TABLE 2.8 DATA FOR THE EQUIPMENT INSTALLATION PROJECT Activity Normal Time (days) Normal Cost ($) Crash Time (days) Crash Cost ($) Immediate Predecessor($) A - 3 2 7,000 10,000 B - 1 1 3,000 3,000 C A 4 2 12,000 40,000 D B 2 1 12,000 28,000 E C 1 1 8,000 8,000 F D,E 4 2 5,000 15,000 G E 2 1 9,000 18,000 Based on the data in the Table, we can make the following network diagram: We see from the diagram that there are three paths for completion: Path 1: A – C – E – G Path 2: A – C – E – F Path 3: B – D – F We now calculate the time taken to complete each path to determine the critical path. Time taken for completion of Path 1 (A – C – E – G): 3 + 4 + 1 + 2 = 10 days Time taken for completion of Path 2 (A – C – E – F): 3 + 4 + 1 + 4 = 12 days Time taken for completion of Path 3 (B – D – F): 1 + 2 + 4 = 7 days From this we can see that Path 2 takes the longest time and hence is the Critical Path. We will start crashing the process on the critical...

...Date of Counseling: 17 October 2011 Subject: Initial counseling For: SGT Pereyra, Francisco J. 6. You are overall responsible for the accountability of your soldiers. I believe that soldiers should work smart and hard during the normal duty day so that we can maximize time off and maintain normal work hours. However, mission will at times dictate weekends or late nights upon approval from the Battalion Commander. We can avoid self-inflicted problems by keeping track of appointments, breaks, and other situations that interfere with the mission. Remember soldiers take the initiative when the example is set. All appointments will be brought to my attention at least 2 days prior, emergencies are understood but they should be the exception rather than the rule. If you believe a soldier should receive time off, bring it to my attention. Keep me informed! Open communication is the key to success. 7. Maintenance of your equipment is essential to success of the mission. You will ensure that your vehicles are properly maintained and service (if any). Your soldiers will be licensed on all platoon equipment. You will strictly enforce SAFETY at all times by word of mouth and example. 8. As Noncommissioned Officers we have the authority to discipline our soldiers. Discipline takes many forms including: on the spot corrections, verbal counseling, formal counseling, corrective training and the commander/1SG can support us with other useful methods including revocation...
