3. Normandin Inc. has an unfunded pension liability of $575 million that must be paid in 20 years. To assess the value of the firm’s stock, financial analysts want to discount this liability back to the present.

  

If the relevant discount rate is 6.8 percent, what is the present value of this liability? (Enter your answer in dollars, not millions of dollars. Do not round intermediate calculations and round your final answer to 2 decimal places.)

4. Although appealing to more refined tastes, art as a collectible has not always performed so profitably. During 2003, Sothebys sold the Edgar Degas bronze sculpture Petit Danseuse de Quartorze Ans at auction for a price of $10,311,500. Unfortunately for the previous owner, he had purchased it in 1999 at a price of $12,377,500.

  

What was his annual rate of return on this sculpture? (Negative amount should be indicated by a minus sign. Do not round intermediate calculations and round your final answer to 2 decimal places.)

Explanation:

PV and FV are related as:

PV = FV/ (1+r) n

r = Rate of interest

n = Number of periods

i)

$ 240 = $ 297 /(1+r)4

(1+r)4 = $ 297/$ 240 = 1.2375

1+r = (1.2375)1/4 = (1.2375)0.25 =1.05471786420082

r = 1.05471786420082 -1 = 0.05471786420082 or 5.57 %

ii)

$ 360 = $ 1,080 /(1+r)18

(1+r)18 = $ 1,080/$ 360 = 3

1+r = (3)1/18 = (3) 0.055555556 = 1.06293507041105

r = 1.06293507041105 -1 = 0.06293507041105 or 6.29 %

iii)

$ 39,000 = $ 185,382 /(1+r)19

(1+r)19 = $ 185,382/$ 39,000 = 4.75338461538462

1+r = (4.75338461538462)1/19 = (4.75338461538462) 0.0526315789473684

= 1.08550476584235

r = 1.08550476584235 – 1 = 0.08550476584235 or 8.55 %

iv)

$ 38,261 = $ 531,618 /(1+r)25

(1+r)25 = $ 531,618/$ 38,261 = 3

1+r = (13.894513995975)1/25 = (13.894513995975) 0.04 = 1.11099916982758

r = 1.11099916982758 -1 = 0.11099916982758 or 11.10 %

2.

As per rule 72, time required to double the investment is:

T = 72/Rate of interest

= 72/6.5 = 11.07692308 or 11.08 years

As per rule 144, time required to quadruple the investment is:

T = 144/ Rate of interest

= 144/6.5

= 22.1538461538 or 22.15 years

3.

PV = FV/ (1+r) n

    = $ 575,000,000/ (1+0.068)20

    = $ 575,000,000/ (1.068)20

    = $ 575,000,000/ 3.72756352870894

     = $ 154,256,257.625515 or $ 154,256,257.63

4.

Total Return Rate = (Final price – Initial price)/Initial price

                        = ($ 10,311,500 - $ 12,377,500)/ $ 12,377,500

                       = - $ 2,066,000/$ 12,377,500

                      = - 0.166915774590992

Annual rate of return = (1+ Total Return Rate)1/years - 1

                                      = (1- 0.166915774590992)1/4 – 1

                                     = (0.833084225409008)0.25 - 1

                                       = 0.955371381687618 – 1

                                       = -0.044628618312382 or - 4.46 %
