Write a class named “Stock” to model a stock. The properties and methods of the class are shown in figure below. The method “ percentage ” computes the percentage of the change of the current price vs the previous closing price. Write a program to test the “Stock” class. In the program, create a Stock object with the stock symbol SUND, name Sun Microsystem V, previous closing price of 100. Set a new current price randomly and display the price percentage.

Each year, Florida's Best Salad Dressing, Inc. (FBSD) purchases 50,000 gallons of extra virgin

olive oil. Ordering costs are $95.00 per order, and the carrying cost, as a percentage of inventory

value is 80 percent. The purchase price to FBSD is $0.50 per gallon. FBSD’s management currently

orders the EOQ each time an order is placed. No safety stock is carried. The supplier is now offering a

quantity discount of $0.03 per gallon if FBSD orders 10,000 gallons at a time. What is the net benefit

in dollars if FBSD takes the discount?

1. Price a European Call & Put and an American Put on a stock that is currently selling at $25 and has a volatility of 25%. The options all have a life of 7 months and a strike price of $26. The 7-month risk free rate is 3% per annum with continuous compounding. a. Use a 12-step binomial tree to price all 3 options b. Use a 13-step binomial tree to price all 3 options c. Use the Black-Scholes-Merton formula to price the European options

2. Use the information in question 1, but now the stock will pay a dividend of $1 in 3 months from today. Price European Call & Put and American Call & Put using a 7-step binomial tree.

The Wildcat Oil Company is trying to decide whether to lease or buy a new computer-assisted drilling system for its oil exploration business. Management has decided that it must use the system to stay competitive; it will provide $4.6 million in annual pretax cost savings. The system costs $9.6 million and will be depreciated straight-line to zero over five years. Wildcat’s tax rate is 21 percent and the firm can borrow at 9 percent. Lambert’s policy is to require its lessees to make payments at the start of the year. Suppose it is estimated that the equipment will have an aftertax residual value of $1,020,000 at the end of the lease.

What is the maximum lease payment acceptable to Wildcat? (Do not round intermediate calculations and enter your answer in dollars, not millions of dollars, rounded to 2 decimal places, e.g., 1,234,567.89.)

The recent outbreak of novel coronavirus (COVID-19) has introduced new challenges to the business environment. It is also having an impact on the global economy with tourism, aviation, education, and hospitality the initially hardest-hit industries. Almost all global supply-chains are affected at some level. Realistically, many sectors will be affected to different degrees, with many organizations implementing policies to limit employee travel and to prepare employees to work from home if necessary and if possible, to ensure the safety of their employees. The outbreak is moving quickly, and most countries are trying to respond quickly to contain the impact. However, the spread of the virus may continue through 2020 and impact the operations of many industries for months to come.
