GASB was established to provide uniformed governmental accounting principles for states and local governments to utilize. If GASB gave in to the rebellion of Texas officials for not complying with Statement 45, it would be similar to parents giving in to their misbehaved children. GASB would lose their authority, power, and trust from the public. If GASB allowed Texas to follow their own accounting rules, other states may follow in their footsteps, and then GASB’s authority would be diminished and no one would be following GAAP. States will recognize that GASB can be easily influenced and choose to do their own specific reporting methods.
One of the main reasons Texas refused to comply with GASB 45 was due to the fact that they felt that it was “impossible to accurately project health care costs as far into the future as GASB requires” (Cheney 2). I’m sure a couple of states have difficulty estimating health care costs, but they still manage to do so regardless because if states don’t comply with GASB, then this will negatively impact states’ credit worthiness and bond rating. GASB establishes and implements their standards because they know that it will result in organized and uniform governmental accounting. GASB doesn’t make rules just for the sake of making rules, but the rules always have meaning. GASB 45 requires governments to use the accrual accounting method to report OPEB as its more efficient than using the pay-as-you-go basis. GASB believes Statement 45 is the best course of action for public entities and everyone should comply.

By using SWOT analysis identify 6 strengths, 3weaknesses, 1 opportunity, and 2 threats. Then to write an analytical text for the case study. Johnson & Johnson Consumer Products, INC. Johnson & Johnson is a household name in baby-care as well as medical products. Nearly every family in the United States has in its house at least one product made by this company. Founded in 1885, Johnson & Johnson is currently an international enterprise, with 170 affiliated companies in fifty-five countries. J&J enjoys a reputation for high-quality products and business integrity. Consumers feel that they can trust J&J products. Trust is a big issue for a firm that makes pharmaceuticals. Customers must believe that the products improve, not endanger, their health. J&J makes a big thing of its credo statement, a four-paragraph guiding philosophy that outlines a commitment to business integrity. According to its credo, the J&J company is required to place a high priority on the needs of customers. Protecting customers is the company’s first concern. All was well until J&J received news that its leading product, Tylenol capsules, had been contaminated with lethal poison. In the United States, Tylenol and other mild pain relievers are sold in the pharmacies and other stores over-the-counter, that is, without a doctor’s prescription. Mr. David Clare, the president of J&J, said that someone had opened the capsules and poisoned them with cyanide. The fact that seven people in the Chicago area died when they took Extra-Strength Tylenol, a common pain-relieving medicine made by J&J, shocked people all over the world. People all over the world were horrified by the deaths of seven innocent people who took Tylenol capsules laced with deadly cyanide. It seemed that anyone could have bought those deadly pills, and anyone could have died from ingesting them. This element of randomness was particularly frightening. After seven innocent people died from taking contaminated Tylenol, sales of the painkiller fell dramatically. The non-aspirin drug’s share of the $1.2 billion painkiller market fell from 35 percent to 7 percent. In a poll, a majority of Tylenol users said they probably would never return to the capsule. But J&J responded to the frightening incident in a notable way. Its executives took a decision that turned out to be not only ethical but profitable, too. Going against all odds, the chairman of J&J decided to spend whatever millions it would cost to recall 31 million bottles of Tylenol capsules from store shelves across the United States. The day after J&J learned that some of its popular Tylenol capsules had been poisoned, the company started withdrawing 31 million bottles of Tylenol from country. They were afraid that other bottles might have been tampered with. Official at the Food and Drug Administration, the U.S. government agency that approves products for sale to the public, feared that the recall would increase the panic already touched off by the poisoning deaths of seven Chicago-area residents who had taken capsules that had been laced with cyanide. The FBI argued that such an expensive action would demonstrate to potential terrorists that they could bring a $5.9 billion corporation to its knees . But J&J chairman’s decision prevailed, and his move proved to be decisive in a remarkable and unparalleled win back of public confidence in his company’s product… Tylenol regained more than 80 percent of the market share it held before the still unsolved poisoning. As a result of the seven deaths in Chicago, Illinois, J&J was able to play a significant role in affecting positive changes in the U.S. pharmaceutical industry and in government regulation of that industry. The company began redesigning the package to restore public confidence. Within twenty-four hours, J&J had contacted many of the companies that would be involved in the redesign. By the end of the week, J&J had decided that the new Tylenol bottle would have three barriers to prevent tampering: a glued box, a ‘shrink’ neckband and an inner seal. To get Tylenol back on the market, J&J spent $ 1 million on engravers to redesign 650 pieces of artwork for the product. Cartons and sealing equipment cost more than $ 5 million during the first few weeks. By the fifth week after the Chicago deaths, the first 500,000 units of the new tamper-resistant Tylenol package were produced. While J&J led industry efforts to protect consumers, the Food and Drug Administration began developing stronger packaging regulations. As a result, all capsules and liquid drugs must now come in tamper-resistant packages. These guidelines do not only protect the consumer but also the pharmaceutical companies such as J&J. Four years after the first incident, another person died after taking poisoned Tylenol from so-called tamper-resistant package. J&J is faced again with the problem of winning back the public trust. To do this, it must get the media on its side.

In this exercise you are asked to choose a currency in which it is assumed you have foreign exchange exposure both in trade (short-run) and investment (long-run). In this exercise you are asked to find both spot and forward exchange rates for a chosen currency and also inflation rates associated with that currency. You are encouraged to read through the exercise first before choosing your currency to ensure the requested data is accessible via the links provided.
Short-Run Exchange Rate Risk
Assume you have a trade receivable denominated in a foreign currency of your choice that is payable to you by your customer in 6 months. At the current spot rate the trade receivable is worth the equivalent of US$5,000,000. To find the current spot rate for the chosen currency pair go to http://www.hsbcnet.com/gbm/fxcalc-disp.[1] Enter 5,000,000 in the “Convert” box, United States dollar in the “From:” box, and your chosen currency in the “To:” box. Click on “Go” for the spot rate, which will be expressed in European terms, that is, units of foreign currency per one US dollar. Enter the name of the chosen currency, the date the site is accessed, and the spot rate in European terms in the table below.
To find a 180 day forward rate for the currency pair, go to http://www.hsbcnet.com/gbm/fwcalc-disp#. For “Amount” you can just enter 1 and enter US dollars in the “Buy” box and the foreign currency in the “Sell” box. For “Value Date” enter “6 Months” and click “Go” for the forward rate. (Clicking on the Inverse box will switch the rate from European to American terms.) Enter the one-year forward rate in the table below. Make sure the forward rate is expressed in the same way as the forward rate, that is, in European terms.
|
Foreign Currency |
Date |
Current Spot Rate in European terms: FX per 1 US dollar |
Six -Month Forward Rate in European terms: FX per 1 US dollar |
Based on the data above, answer the following questions:
|
At the current spot rate how much in the foreign currency are you owed in 6 months? Assuming you fully hedge your FX exposure in the forward market, how many US dollars will you receive in 6 months? Is the foreign currency selling in the forward market at a premium, i.e. it appreciates relative to the spot rate, or a discount, i.e., it depreciates relative to the spot rate? Provide numbers to support your answer. |
Long-Run Exchange Rate Risk
Assume you have undertaken a 3-year investment abroad with expected cash flows denominated in your chosen currency. At the current spot rate those cash flows are expected to provide a positive net present value (NPV) in US dollar terms. Based on relative purchasing power parity you are asked to estimate future spot rates over the next three years based on comparative inflation data.[2] With that data complete the table below.
|
S0 = Current Spot Rate in European Terms (Foreign currency per US dollar) |
E(St) = Expected Exchange Rate Spot Rate in t Years in European Terms (Foreign currency per US dollar) |
hUS= Annual Inflation Rate in the United States |
hFC = Annual Foreign Country Inflation Rate |
Using the data above and textbook equation (18.3) E(St) = S0 ? [1 + (hFC - hUS)]t and assuming the estimated inflation rate in Year 1 also holds for Years 2 and 3, please respond to the following:
|
Based on relative purchasing power parity, estimate S1. Based on relative purchasing power parity, estimate S2. Based on relative purchasing power parity, estimate S3. Based on relative purchasing power parity, has the foreign currency appreciated or depreciated against the US dollar? Explain. Based on relative purchasing power parity, has the NPV of the investment project increased or decreased in US dollar terms? Explain. |
[1] Please note currencies are grouped according to their region: Americas (where the United States dollar may be found), Asia-Pacific, Europe, and MENA. Please advise your instructor should this or any other link in the assignment be broken.
[2] Sources of Inflation data include http://stats.oecd.org/ for OECD countries and http://data.worldbank.org/indicator/FP.CPI.TOTL.ZG at the World Bank site. It is viewed important to be consistent in the definition and source of inflation numbers for the US and the other currency that you use for the relative PPP equation. The most basic definitions of inflation are consumer price index (CPI), producer price index (PPI), and GDP deflator. Estimates of the next year’s inflation are preferred but it is also common to use the past year’s inflation as the best estimate of next year’s and subsequent years’ inflation. You are encouraged to share any useful websites for this data you find with the class.
