Its fiscal 2015 interest expense was $227 million, and its assumed statutory tax rate was 37%. Kellogg has an estimated market beta of 0.70. Assume that the expected risk-free rate is 2.5% and the expected market premium is 5%.Kellogg's stock closed at $80.19 on December 31, 2015. On that same date, the company had 420,315,589 shares issued, of which 70,291,514 shares were in treasury.
