Merger Valuation with Change in Capital Structure

VolWorld Communications Inc., a large telecommunications company, is evaluating the possible acquisition of Bulldog Cable Company (BCC), a regional cable company. VolWorld's analysts project the following post-merger data for BCC (in thousands of dollars, with a year end of December 31):

2016 2017 2018 2019 2020 2021
Net sales $450.0 $518.0 $  555.0 $  600.0 $  643.0
Selling and administrative expense 45.0 53.0 60.0 68.0 73.0
Interest 40.0 45.0 47.0 52.0 54.0
Total net operating capital 800.0 850.0 930.0 1,005.0 1,075.0 1,150.0
Tax rate after merger: 40%
Cost of goods sold as a percent of sales: 45%
BCC's pre-merger beta: 1.30
Risk-free rate: 5%
Market risk premium: 7%
Terminal growth rate of free cash flows: 6%

If the acquisition is made, it will occur on January 1, 2017. All cash flows shown in the income statements are assumed to occur at the end of the year. BCC currently has a capital structure of 40% debt, which costs 8.50%, but over the next 4 years VolWorld would increase that to 50%, and the target capital structure would be reached by the start of 2021. BCC, if independent, would pay taxes at 25%, but its income would be taxed at 40% if it were consolidated. BCC's current market-determined beta is 1.30. The cost of goods sold is expected to be 45% of sales.

What is the unlevered cost of equity for BCC? Do not round intermediate calculations. Round your answer to two decimal places.

RingettePlayer

-firstName: String

-lastName: String

-allergies: String

-jerseyNumber: int

-birthYear: int

Constructors

+RingettePlayer()    

+RingettePlayer(String, String)

+RingettePlayer(int)

+RingettePlayer(String, String, String, int)   

+getters/setters for all

+getInformation():void

+display():void

+toString(): String

Default Values for Attributes

When values are not provided for attributes, the following are the values that should be set for the attributes. Note that these are the only attributes that are to be in the class.

  • firstName and lastName default: “Unknown”
  • allergies default: “”
    • The default for allergies is an empty string
  • jerseyNumber and birthYear: 0

Constructor Details

Create four constructors in the RingettePlayer class based on the following requirements.

  • Default no-parameter constructor
    • Create a default no-parameter constructor for the RingettePlayer which sets attributes to their default values.
  • RingettePlayer(String, String)   
    • First and last names passed as parameters and set.
    • the jersey number, birthYear and allergies set to their default values
  • RingettePlayer(int)
    • jerseyNumber passed as a parameter
    • Other attributes are set to their default values
  • RingettePlayer(String, String, String int, int)
    • Values for all attributes are passed in as parameters and used to set object attribute values.

Controller Class Functionality

In the main method create three object based on the following specifications. You can use your own name for the variable name.

  • The first object created should be created using the constructor that accepts two Strings to set the first and last name in the instance (example: “Brielle”, “Jones”). The user does not have to be prompted for these values. They are to be set as hard coded values.
  • The second object created should be created with the default constructor and the setters used to set her first name (“Marley”), last name (“Stephens”), allergies (“Dust”) and jersey number (9). The user does not have to be prompted for these values. They are to be set as hard coded values.
  • The third object should be created using the default constructor. The values for this object are to be obtained from the user by using the getInformation() method. The output below shows an example with user entered data.
    • Note that when the program runs, they would be prompted for the values of this object as the first interaction with the user.

Additional Requirements

  • After creating each of these objects in the main method, have the program display their values to the console.

Cain Components manufactures and distributes various plumbing products used in homes and other buildings. Over time, the production staff has noticed that products they considered easy to make were difficult to sell at margins considered reasonable, while products that seemed to take a lot of staff time were selling well despite recent price increases. A summer intern has suggested that the cost system might be providing misleading information.

The controller decided that a good summer project for the intern would be to develop, in one self-contained area of the plant, an alternative cost system with which to compare the current system. The intern identified the following cost pools and, after discussion with some plant personnel, appropriate cost drivers for each pool. There were:

Cost Pools Costs Activity Drivers
Receiving $ 600,000 Direct material cost
Manufacturing 5,500,000 Machine-hours
Machine setup 900,000 Production runs
Shipping 1,000,000 Units shipped

In this particular area, Cain produces two of its many products: Standard and Deluxe. The following are data for production for the latest full year of operations.

Products
Standard Deluxe
Total direct material costs $ 235,000 $ 165,000
Total direct labor costs $ 650,000 $ 270,000
Total machine-hours 146,000 104,000
Total number of setups 85 115
Total pounds of material 17,000 10,000
Total direct labor-hours 6,100 3,850
Number of units produced and shipped 18,000 7,000

The intern decides to look more closely at the manufacturing activity and determines that it can be broken down into two activities: production and engineering. Production covers the costs of ongoing manufacturing while engineering includes those activities dealing with engineering changes, design modifications, and so on.

The costs attributed to production are $1,764,000 and the costs attributed to engineering are $1,372,000. After discussion with plant engineers, the intern decides that the best cost driver for engineering is setups, because most of the work arises from changes in the way the product is run.

Required:

a-1. Compute the totals of the cost driver rates shown below.

a-2. What unit product costs will be reported for the two products if the revised ABC system is used?

Compute the totals of the cost driver rates shown below. (Round intermediate calculations and "Manufacturing" answer to 2 decimal places.)

Receiving % of material dollars

Engineering per setup
Machine setup per setup
Shipping per unit
