Assume the zero-coupon yields on default-free securities are as summarized in the following table:

Maturity	1 year	2 years	3 years	4 years	5 years
Zero-Coupon Yields	4.50%	5.00%	5.30%	5.60%	5.80%

Consider a four-year, default-free security with annual coupon payments and a face value of $1,000 that is issued at par. What is the coupon rate of this bond?

The par coupon rate is:

(Round to two decimal places.)
