Emily's trust fund has a value of 100,000 on January 1, 1997. On April 1, 1997, 10,000 is withdrawn from the fund, and immediate
mafiozo [28]

Answer:

(a) Dollar Weighted Rate of return = 0.27

(b) Simple interest-based rate of return = (115000- 100000)/ 100000 = 0.15

(c) Since, the data or investment portfolio of Emily is of one year, we can calculate the money weighted rate of return but time weighted rate of return couldn’t be calculated.

Explanation:

For (a) Dollar Weighted Rate of return = 0.27

<em>Calculations:</em> 115000 = ((-10000) *(1 + r) ^ ((365-90)/365)) + 100000*(1+r)

So, using calculator we found r= 0.27  

Here we’ve equated the value of portfolio at Jan 1, 1998 with Value of portfolio on Jan 1, 1997 and using the formula for money weighted average rate of return we’ve found the rate of return. Since, we are taking annual money weighted average rate of return, so we don’t include the value of July cash flow, i.e. $5000.

For (b) Simple interest-based rate of return = (115000- 100000)/ 100000 = 0.15  

Since, the distribution of deposits and withdrawals is uniform, so it is simply the newer value minus original value divided by the original value and is most likely to percentage calculation.

(c) Since, the data or investment portfolio of Emily is of one year, we can calculate the money weighted rate of return but time weighted rate of return couldn’t be calculated.

If an individual investor uses the services of a broker to buy and sell stocks that are currently being traded in the stock mark
sergejj [24]

Answer:

a. False

Explanation:

A "primary transaction" refers to the selling of <em>new stocks and bonds</em> for the first time towards the public. A great example of this is the "Initial Public Offering" <em>(IPO)</em> which allows "public share issuance."

On the other hand, a "secondary transaction" refers to the<em> trading of investors among themselves.</em> There is no involvement of the issuing companies here. So, this means that if an investor uses the services of a broker to buy and sell stocks that are currently being traded in the stock market,<u> the transaction</u><u> doesn't directly involve the issuing compan</u><u>y.</u> This kind of transaction is then called "secondary."

So, this explains the answer.

A firm is considering a project with annual cash flows of $300,000. The project would have a five-year life, and the company use
stealth61 [152]

Answer:

$1,081,434

Explanation:

<em>At indifference point, the present value of cash outflow equals  present value of cash inflow.</em>

Present value of cash inflow = Annual cash inflow * PV annuity factor (12%, 5 years)

Present value of cash inflow = $300,000*3.60478

Present value of cash inflow = $1,081,434

So, the amount at which the firm would be indifferent between accepting or rejecting the investment is $1,081,434.
