Having heard about IPO underpricing, I put in an order to my broker for 1,170 shares of every IPO he can get for me. After 3 months, my investment record is as follows:

IPO Shares Allocated to Me Price per Share Initial Return

A 670 $ 10 8 %

B 370 22 15

C 1,170 8 2

D 0 11 20

a. What is the average underpricing in dollars of this sample of IPOs? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
