STEPHENSON REAL ESTATE RECAPITALIZATION Stephenson Real Estate Company was founded 25 years ago by the current CEO, Robert Stephenson. The company purchases real estate, including land and buildings, and rents the property to tenants. The company has shown a profit every year for the past 18 years, and the shareholders are satisfied with the company’s management. Prior to founding Stephenson Real Estate, Robert was the founder and CEO of a failed alpaca farming operation. The resulting bankruptcy made him extremely averse to debt financing. As a result, the company is entirely equity financed, with 8 million shares of common stock outstanding. The stock currently trades at $37.80 per share. Stephenson is evaluating a plan to purchase a huge tract of land in the southeastern United States for $85 million. The land will subsequently be leased to tenant farmers. This purchase is expected to increase Stephenson’s annual pretax earnings by $14.125 million in perpetuity. Jennifer Weyand, the company’s new CFO, has been put in charge of the project. Jennifer has determined that the company’s current cost of capital is 10.2 percent. She feels that the company would be more valuable if it included debt in its capital structure, so she is evaluating whether the company should issue debt to entirely finance the project. Based on some conversations with investment banks, she thinks that the company can issue bonds at par value with a 6 percent coupon rate. From her analysis, she also believes that a capital structure in the range of 70 percent equity/30 percent debt would be optimal. If the company goes beyond 30 percent debt, its bonds would carry a lower rating and a much higher coupon because the possibility of financial distress and the associated costs would rise sharply. Stephenson has a 23 percent corporate tax rate (state and federal).

1. If Stephenson wishes to maximize its total market value, would you recommend that it issue debt or equity to finance the land purchase? Explain.

2. Suppose Stephenson decides to issue debt to finance the purchase. What will the market value of the Stephenson Real Estate Company be if the purchase is financed with debt?

3. What is the price per share of the firm’s stock? (Hint: Stock price per share = Total equity / # of outstanding shares)

Manufacturing facilities may experience production delays due to unexpected natural events, such as fires, or anticipated, but ignored, defects or human-made problems. What are three (3) to five (5) contract clauses and/or negotiated business terms that you would want to include as the purchaser of manufactured items critical to your company's success to avoid or mitigate risks associated with production interruptions.

Your company has been approached to bid on a contract to sell 5,200 voice recognition (VR) computer keyboards a year for four years. Due to technological improvements, beyond that time they will be outdated and no sales will be possible. The equipment necessary for the production will cost $3.9 million and will be depreciated on a straight-line basis to a zero salvage value. Production will require an investment in net working capital of $435,000 to be returned at the end of the project, and the equipment can be sold for $385,000 at the end of production. Fixed costs are $610,000 per year, and variable costs are $83 per unit. In addition to the contract, you feel your company can sell 13,000, 15,100, 18,700, and 11,200 additional units to companies in other countries over the next four years, respectively, at a price of $189. This price is fixed. The tax rate is 23 percent, and the required return is 12 percent. Additionally, the president of the company will undertake the project only if it has an NPV of $125,000. What bid price should you set for the contract? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)

. ThyssenKrupp Elevator Canada INTRODUCTION During a lunchroom break, a male employee at ThyssenKrupp decided to take up a dare from a fellow colleague for $100 and the Jackass-like prank was videotaped then posted to YouTube. When it came to the attention of the HR manager and other senior management, the employee was fired for violating company policy. The employee argued in court that the organizational culture allowed such behavior. But would the Ontario Labour Relations Board (OLRB) agree?

BACKGROUND ThyssenKrupp Elevator Canada was subcontracting elevator installation at a construction site in downtown Toronto where a large office building was being built. All the workers on the site, including those from ThyssenKrupp, and the main contractor of the site, PCL Construction, were male and the culture of the workplace was described as a “macho” environment where pranks were played. There were reportedly pictures of women and provocative calendars hanging on walls, as well as signs displaying vulgar humor. There was little concern about these as access to the building was restricted to people involved in the construction project. One of ThyssenKrupp's employees at the site was an elevator mechanic. He and several other employees engaged in what he called “picking” on each other and playing pranks to keep things light at work. They also watched pornographic scenes on a worker's iPod and episodes of the television show Jackass, which features individuals doing stupid activities on dares.

ESCALATION OF PRANK BEHAVIOUR Over a period of a few weeks, the mechanic and other employees performed more and more pranks that copied some of the ones they saw on the Jackass show. Typically these events took place in the basement lunchroom where employees gathered for breaks and meals, to change clothes, and to socialize. Soon, money was being offered on dares to do certain actions. For example, one ThyssenKrupp employee accepted a dare that involved a $60 payment—money collected from fellow employees, including three foremen. The dare involved the employee eating spoiled food found in the common refrigerator of the lunchroom. A couple of weeks after the first dare, the mechanic was observed playing with a stapler in the lunchroom on a break. One of the foremen walked in and jokingly said, “What are you going to do with that? Why don't you staple your nuts to something?” The mechanic jokingly replied that he'd do it “if you get enough money.” Though he claimed it was intended as a joke, word spread within a few hours, and soon $100 was raised among seven other ThyssenKrupp and three PCL employees. Another four people were in the lunchroom later that afternoon watching when the mechanic decided to go ahead with the staple dare. He proceeded to drop his work uniform trousers and staple his scrotum to a wooden plank, which was met by “cheering and high fives,” according to the mechanic. With the mechanic's knowledge, the prank was filmed on video. Included on-camera were all those employees present, wearing full worksite uniforms, PCL logos on hats, and TK shirt patches—all easily identifiable and recorded by a worker who was present that day. The mechanic was advised at a later date that the event was posted on YouTube. Initially, the mechanic did nothing about the YouTube posting but eventually asked for it to be taken off the site. To ensure this was done, the mechanic went back to YouTube searching for the video clip, but couldn't find it. He assumed it had been removed, however, it was not—he just didn't search correctly. In total, the video clip was assessable on YouTube for two weeks, during which time many employees in the construction industry watched it. It was during these two weeks that ThyssenKrupp became aware of the video after the HR department received an email with a link to the video, and several people discussed it with a ThyssenKrupp executive at a construction labor relations conference. Conference participants insisted the employee was from ThyssenKrupp, and they questioned how the company could allow something like that to happen during work hours. At this point, ThyssenKrupp management reviewed the video one more time and decided that the mechanic had violated its workplace harassment policy, which prohibited “practical jokes of a sexual nature which cause awkwardness or embarrassment.” The mechanic was fired for “a flagrant violation” of ThyssenKrupp's harassment policy and risking the company's reputation.

CULTURE AT FAULT Upon being fired from his job, the mechanic filed a grievance with the OLRB. He argued that dismissal was too harsh given the culture of the workplace which was accepting of that type of behavior. He also said no one told him not to do it, no one expressed displeasure, and no one mentioned they were offended. He argued that other employees had done stunts but questioned why he was the only one disciplined for his actions. He also claimed to have never seen the workplace harassment policy, even though it was part of the orientation package. THE DECISION In July 2011, the OLRB found the mechanic's misconduct on the employer's premises, plus his permission to record it, “patently unacceptable in almost any workplace.” The fact that his employer was easily identified in the video clip contributed to the decision. The fact that the mechanic claimed not to have known about the corporate harassment policy was irrelevant—he should have known better. The OLRB also dismissed as irrelevant that no one protested or objected to the prank during the lunch break, which the mechanic argued was “not during work hours.” The court stated that ThyssenKrupp has an interest in preventing such horseplay and stunts in the workplace. They are in a safety-sensitive industry and such employee misconduct places the firm's reputation in jeopardy. The seriousness of the mechanic's misconduct also superseded any other factors, such as his claim of being a good employee with a clean record and the argument around the culture. There was no evidence that the company was aware of other pranks, and his role as the principal offender wasn't diminished by the culture, said the board. In dismissing the mechanic's grievance, the board stated, “If (ThyssenKrupp) employees want to emulate the principles of Jackass by self-abuse, they may be free to do so when they are not on the (employer's) premises and cannot be identified as being associated with (ThyssenKrupp).”

Questions

(1) What corporate values did ThyssenKrupp refer to when deciding to terminate the mechanic? What are the health and safety issues involved here? Do you think an informal work environment is leading towards a lack of strict health & safety policy at the workplace?

(2) Considering that the mechanic claimed that the ThyssenKrupp culture contributed to such behavior, in your opinion, does ThyssenKrupp need to change its corporate culture? If not, why not?

(3) Are there any Tort issues involved here? What other legal issues are involved here? Explain.

(4) Did the Ontario Labour Relation Board (OLRB) accept the defense that organizational culture contributed to the employee behavior? Explain their reasoning. Considering the company’s work environment, what factors need to be considered while updating the company’s health & safety policy?

(5) If this case goes to court, what arguments the Plaintiff’s Lawyer, representing the fired worker, would present before the court?

(6) What would be the line of Defense for the Lawyer of Thyssen Krupp Elevator?

Suppose we are thinking about replacing an old computer with a new one. The old one cost us $1,640,000; the new one will cost, $1,975,000. The new machine will be depreciated straight-line to zero over its five-year life. It will probably be worth about $420,000 after five years. The old computer is being depreciated at a rate of $344,000 per year. It will be completely written off in three years. If we don’t replace it now, we will have to replace it in two years. We can sell it now for $540,000; in two years, it will probably be worth $156,000. The new machine will save us $368,000 per year in operating costs. The tax rate is 24 percent, and the discount rate is 11 percent.
