Having heard about IPO underpricing, I put in an order to my broker for 2,000 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		700		$	10			7	%
B		500			20			13
C		2,000			8		−	1
D		0			12			25

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.)
