Q.2: Explain the advantages and disadvantages associated with promoting internally to a leadership

Benefits of promoting from within

In the business world, promoting from within can provide benefits in several areas:

Recruiting - Being known as an employer who offers opportunities for career advancement is attractive to prospective hires. Interviewees are impressed when they meet employees who've steadily moved up the ranks.

Retention - When new employees see that opportunities exist for them and that there's a track record of hiring from within, they tend to stay longer with your company. Cost savings - The cost of recruiting, interviewing, and onboarding new employees can outweigh the cost of training current employees for certain new skills. It can take internal candidates much less time to become effective in a new position because they are already familiar with the company culture and its goals.

Flexibility - Newly promoted staff can assist with training their replacements. They are available for questions and can occasionally fill in at their old position if needed in emergencies.

Culture fit - Existing employees fit in with the company culture (or else I assume you would not be promoting them). Conversely, despite the most probing interview questions, you're never positive about whether a new hire will be a good culture fit or not.

For disadvantages.

1) The job may require skills not found in your company.

2) If you promote only from within, you limit the sources from which to draw candidates and you may be restricted to promoting a person significantly less qualified than someone from outside your company.

3) People who have worked in other companies bring with them new and different ideas and know-how that can benefit your team.

4) Outsiders look at your activities with a fresh view, not tainted by over-familiarity. 5) One of the major problems in interdepartmental transfers is the reluctance of department heads to release efficient and productive workers to other departments. One of the first actions of a company planning a policy of internal recruitment should be to notify all department heads and team leaders that it will overrule any attempts to keep people who could be more valuable to the organization from transferring to another position. It should also be mentioned that people who are passed over for better positions in other departments are unlikely to remain with the company, and probably will seek another job elsewhere - so both the department and the company will lose a valuable employee

CS605 Software Engineering II Assignment 4 (June 2010)

Question:
Suppose you are a project manager of a company xyz. You have been asked to compute the earned value analysis of a software project. The software project has 70 planned work tasks that are estimated to require 620 person-days to complete. At the time you have been asked to do the earned value analysis, 13 tasks have been completed. However, the project schedule indicates that 16 tasks should have been completed. The following scheduling data in person-days are available:




















You are required to compute the SPI, schedule variance, percent scheduled for completion, percent complete, CPI, and cost variance for the project.


Solution:


Budgeted cost of work scheduled (BCWS)
11 + 8 + 5 + 13 + 11 + 15 + 8 + 7 + 10 + 12.5 + 6 + 3 + 10 + 5 + 6 = 130.5
Budgeted cost of work performed (BCWP):
11 + 8 + 5 + 13 + 11 + 15 + 8 + 7 + 10 + 12.5 + 6 + 3 = 109.5
Budget at Completion
620
Schedule performance index, SPI = BCWP/BCWS = 109.5/130.5 = 0.83
Schedule variance, SV = BCWP – BCWS = 109.5 - 130.5 = -21
Percent scheduled for completion = BCWS/BAC = 130.5/620 = 0.21
Percent complete = BCWP/BAC = 109.5/620 = 0.17
Actual Cost of Work Performed
10 + 9 + 4 + 13.5 + 11 + 16 + 10 + 7 + 9 + 13 + 5 + 5 = 112.5
Cost performance index, CPI = BCWP/ACWP = 109.5/112.5 = 0.97
Cost variance, CV = BCWP – ACWP = 109.5 – 112.5 = -3

Given the following information for the stock of Foster Company, calculate its beta.





















Question 2: 20 marks

ABC Company is considering investing in either of the two outstanding bonds. Both bonds have Rs.2,000 par values and 10% coupon interest rates and pay annual interests. Bond A has exactly 3 years to maturity, and bond B has 5 years to maturity.
a) Calculate the value of bond A if the required rate of return is 14%.
b) Calculate the value of bond B if the required rate of return is 14%.
c) If ABC wants to minimize the Interest Rate Risk, which bond should be purchased? Why.






Idea Solution

Question stock beta#1

Vu handout page#105

Average Required ROR for all rational investors in an Efficient Market can be estimated using the CAPM Theory: Beta and Risk Free Rate of Return. 
Total Rate of Return (ROR) for Single Stock  = Dividend Yield + Capital Gain.  GORDON’S FORMULA FOR COMMON STOCK PRICING OR VALUATION USES REQUIRED RETURN r = DIV/Po + g.  In Efficient Markets, Price of Stocks is based on Market Risk (or Beta). We can formulate the required rate of return in terms of Beta risk so how can we use beta coefficient to calculate the required rate of return for the average investor in the market. The answer to it is the

Vu handout page # 114

Po*  =  DIV1  /  [ (rRF  +  (rM  - rRF )  βA ) -   g] 

Where
Po*=80

DIV1= 5

g=  7%
rRF = 6%
rM   = 10%
βA = ?

Now put the values and get answer which is = βA 1.8125


Question#2
Bond valuation
Bond Pricing Equation:   vu handout page#123

Bond Price = PV = C1/ (1+rD) + C2/ (1+rD) t2+ C3 / (1+rD)t3 +     ….. + PAR / (1+rD)n3

Where

Pv = bound value
 C= coupon payment Pa   =  2000*10.100= 200
rD=  required rate of return = 14%=0.14
PAR = par value or face value=   2000

Maturity period
Bound A =   t  3      n3
 Bound B =   t 5     n5

Answer:

(a)Bond A =    value  Rs: 1967
(b)Bound B=   value Rs:   1928

(b)Interest rate risk
Definition
The possibility of a reduction in the value of a security, especially a bond,  resulting from a rise in interest rates. This risk can be reduced by diversifying the durations of the fixed-income investments that are held at a given time.

According to LAWARENCE J. GITMAN 12th EDITION FINANCIAL MANAGEMENT  interest rate risk is the market interest rate fluctuation  that directly affect the bound s value that have constant coupon payment, to reduce the fear of  market interest risk diversify the portfolio as it can be spread and chose the bound with shorter duration……

So bound B is perfect decision having the shorter maturity period than bond A  

ACC501 2 Solution June 2010

ABC Co. just paid a dividend of Rs.7.50 per share. The company will increase its dividend by 15% next year, and then will reduce this dividend growth rate by 5% annually until it reaches the industry average of 5 percent, after which the company will keep a constant growth rate forever. If the required return on ABC stock is 14.50 percent, what will be a share of stock sell for today?

Here we have D0= 7.5. Supernatural growth rate Gn = 15%. Ks=14.5%
Then in Y1 & Y2, G= 15%-5% = 10% & in Y3 it is 10%- 5%.= 5%


Step 1. Calculate the dividends expected at the end of each year during the supernormal growth period.

Step 2. The price of the stock is the PV of dividends from Time 1 to infinity, so in theory we could project each future dividend, with the normal growth rate, gn = 5%, used to calculate D2 and subsequent dividends. However, we know that after D2 has been paid, which is at Time 2, the stock becomes a constant growth stock. Therefore, we can use the constant growth formula to find P2, which is the PV of the dividends from Time 2 to infinity as evaluated at Time 2.
First, we determine D3 for use in the formula, and then we calculate P2 as follows: P2=D3/(Ks-g).

Step 3. Now that the cash flows have been placed on the time line, we can discount each cash flow at the required rate of return, ks=14.5%. We could discount each cash flow by dividing by (1.145)t, where t=1 for Time 1, t=2 for Time 2. This produces the PVs shown to the left below the time line, and the sum of the PVs is the value of the supernormal growth stock.

0 Gs=15% 1 Gs=10% 2 g=5% 3

|------------------------|---------------------------|-----------------------------|

D0=7.5 D1=8.625 D2=9.4875 D3=9.04

P2=95.11

a. Terminal or Horizon date is at end of 3 Yrs when Non-constant growth stops.

b. Do=7.5, Gs

= 15% = 0.15, N=2 yrs, g=5%, Ks=14.5%

So D1 = Do(1+Gs) = 7.5*(1+15%) = 7.5*1.15 = $8.625

AT Y2, Gs = 15%-5% = 10%

D2 = D1(1+Gs) = 8.625*1.10 = $9.4875

After 2 yrs, supernatural growth is over & normal growth of 5% starts till infinity

So D3 = D2(1+g) = 9.4875*(1+5%) = 9.4875*1.05 = $9.04

So P2 = D3/(Ks-g) = 9.04/(14.5%-5%) = 9.04/9.5% = $95.11

So Horizon value = D1/(1+Ks)^1 + D2/(1+Ks)^2 + (P2+D3)/(1+Ks)^3

ie HV = 8.625/1.145 + 9.4875/(1.145)^2 + (95.11+9.04)/(1.145)^3

ie HV = 7.53 + 7.24 + 69.38

ie HV = 84.15

So Horizon value of Stock is $84.15

So Share of Stock will sell today for $84.15

Idea


SOLUTION:

(a) The speech which I shall deliver to the primary school teachers will be a persuasive speech. Reason behind this is persuasive speech is delivered when behavior or opinion change is the objective. The objective here is to change the attitude and the behavior of the teachers. To persuade them to avoid physical punishment .so persuasive speech is the best choice for me in this case.



(b) I will prefer extemporaneous mode of delivery of speech. My goal is to change the behavior of my audience. If I adopt any other style of speech like reading from a manuscript, then it will be difficult for me to deliver the lecture. Another option for me is to memorize the speech and deliver it. But if I forgot in the middle of the presentation then it is a very embarrassing situation. Only the extemporaneous mode of delivery is the best choice. I can deliver the lecture in a natural way without facing any difficulty.


(c) Seating arrangement is a very important element for any gathering. Whether it is a lecture, business meeting, seminar or an informative lecture. The seating formation which I shall follow is V formation. Reason behind this is the presenter and the visual aids are easily visible to the audience.moreover, as the number of my audience is 15, so I think that this is the best arrangement for the session. V formation is a modified form of conventional class room style. It is a little bit different and interesting for the audience.

Room Setup For Presentations & Training, Marie Wallace, Jan 01, 2002.



(d) Visual aid adds beauty to the speech and lectures. They emphasize the message and the idea that is being presented. When I am delivering a speech so computer will be my choice. No doubt, there are some limitations like expensiveness, requirement of computer and graphic skills and a darkened room. but the advantages are far more than the drawbacks. I can add PowerPoint slides, videos, photos and animation to my speech. And I can make changes even at the eleventh hour.
