What is the discount yield, bond equivalent yield, and effective annual return on a $4 million commercial paper issue that currently sells at 97.50 percent of its face value and is 145 days from maturity?

6.21%

Explanation:

Discount of the bond can be calculated by subtracting the purchase price of the bond from the face value. Discount Yield is the ratio of discount on the bond to the future value of the bond.

Discount Yield = [(F - P)/F] x [360/t]

Where

F = Face Value = $1,000 ( assumed)

P = Present value  = $1,000 x 97.5% = $975

t = 145 days

Placing the value in the formula

Discount Yield = [($1,000 - $975)/$1,000] x [360/145] = 0.0621 = 6.21%

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
