1. Venture capitalists often will describe long-term financing stages of a company using an “alphabet soup” of terminology. For example, Series A financing, etc.

What are the four stages of investment in this alphabet soup, and what do they represent?

Given that business is about maximizing stakeholder wealth and given that there are laws governing the process by which this is accomplished, is there even room for ethics in business? In other words, if organizations (and organizational members) follow the law, is there any additional need for ethical considerations? When organizations maximize stakeholder wealth, aren't they already doing the "right" thing according to the design and purpose of organizational existence?

A converging-diverging rocket nozzle is connected to a combustion chamber filled with gas at a total pressure of 1200 kPa and a total temperature of 2400 K. The design exit Mach number is 2.9 and the nozzle throat area is 50 cm2 . Assume the gas behaves as an ideal gas with k = 1.3 and a molecular weight of 24 kg/kmol. Determine (a) The back pressure necessary to induce the design Mach number at the nozzle exit. (b) The design exit area for isentropic supersonic flow. (c) The static pressure at the throat when the flow is choked. (d) The mass flow rate through the nozzle when the flow is choked.

A farmer has been in the habit of always planting potatoes on his farm. In previous years, the seeds for the potatoes were planted in the spring, and were ready to harvest in mid-July. After that, a second planting took place in late July, which was ready to harvest in early October.

This year, however, there is concern that a blight might destroy some or all of the potato crop. One thing he could do would be to plant a different crop such as peas which would not be affected by the blight. The peas would have only a single planting at a cost of $40,000. This planting would yield a crop in October worth $70,000 if the weather turns out to be good, or $30,000 if the weather turns out to be poor. There is a 60% chance that the weather will be good.

If, however, he decides to plant potatoes, he will have to worry about the blight (but the weather has little effect on the potato crop and can be ignored). The potato crop would cost $60,000 to plant. There is a 10% chance of a severe blight, which would destroy the crop, and render any attempt at a second planting in late July not worth doing. A mild blight (20% chance) would partially destroy the crop, making it worth only $35,000, while having no blight (70% chance) would produce a crop worth $80,000. After either a mild blight or no blight, a second planting could be undertaken, with the same costs and revenues as the first. The probability of a severe, mild, or no blight would be 15%, 30%, and 55% if the first planting had a mild blight, but would be 0%, 5%, and 95% if the first planting had no blight.

NOTE: The crop planted in the Spring will be either peas or potatoes; doing a bit of both is not an option in this problem.

You are in networking at a large international company. Your company recently decided to implement a cross-training initiative and you have been selected to give a presentation to an audience of non-networking professionals working at various departments in your company.

Your presentation must be clear and concise enough to convey technical information to professionals who have a limited understanding of how networking actually works. However, it must also be accurate enough that your audience can understand how their company roles (such as scheduling resource-hogging reports, allowing contractors access to the system, and setting the hours international customers can place orders on your company’s system) can impact the company’s network, particularly in terms of security.

You decide to use the OSI model to explain the fundamental characteristics and components of networks because it is visual and presents the complexity of network communication in 7 layers.

Draft your speaker notes to hand off to an assistant who will turn your notes into a graphic-rich presentation. Each of your answers should be about 150-250 words long.

Note: Your assignment is to draft speaker notes. Do not create a presentation and do not write a paper.

1. Overview of Networking and Security

You decide to begin your presentation by providing your audience an overview of networking, with an emphasis on security and why it is important for all company roles to assist in securing the company’s network.

Discuss the potential security risks for each layer of the OSI model and the risks in each of the following:

• Distributed vs. centralized computer systems and why your department chose to be distributed/centralized
• Different network topologies and why your department chose the topology it did
• Why standards bodies are essential in networking and how your department complies with standards
• The importance of communication protocols and which one(s) your department chose
• The differences between LAN, WAN, and wireless technologies, and how your department incorporated each
• The responsibilities associated with providing telecommunications services such as security, privacy, reliability, and performance

2. Routing and Switching

Describe basic routing and switching in the context of the OSI model (i.e., in which layer routing, switching, and cabling occur). To underscore your department’s commitment to achieving 24/7 availability, describe 3 strategies your department uses to ensure the availability of network access in switched and routed networks.

3. Effective Security Policy

Describe at least 3 characteristics of an effective security policy, emphasizing the ways in which all departments in the company are responsible for helping secure the company network.

4. Security Strategies

Explain strategies your department used to build security directly into the design of your company network.

5. Malware

Define malware in layperson-friendly language and identify at least 2 strategies your department has put into place to protect your company’s network against malware.

6. Closing

Summarize your presentation.

Hastings Corporation is interested in acquiring Vandell Corporation. Vandell has 1 million shares outstanding and a target capital structure consisting of 30% debt; its beta is 1.20 (given its target capital structure). Vandell has $8.00 million in debt that trades at par and pays a 7% interest rate. Vandell’s free cash flow (FCF₀) is $1 million per year and is expected to grow at a constant rate of 5% a year. Vandell pays a 30% combined federal and state tax rate. The risk-free rate of interest is 4%, and the market risk premium is 6%. Hasting’s first step is to estimate the current intrinsic value of Vandell.

1. What are Vandell’s cost of equity and weighted average cost of capital? Do not round intermediate calculations. Round your answers to two decimal places.

   Cost of equity:   %

   WACC:   %

2. What is Vandell’s intrinsic value of operations? (Hint: Use the free cash flow corporate valuation model.) Do not round intermediate calculations. Enter your answer in millions. For example, an answer of $1.23 million should be entered as 1.23, not 1,230,000. Round your answer to two decimal places.

   $   million

3. What is the current intrinsic value of Vandell’s stock? Do not round intermediate calculations. Round your answer to the nearest cent.
