MSU Rollforward

Market Stock Units ("MSUs") are exchangeable for between 0% to 150% of the Company's common shares at the end of the vesting period based on the trailing 30 or 60 day average closing price of the Company's common stock. The value of the MSUs was determined using a geometric brownian motion model that, based on certain variables, generates a large number of random trials simulating the price of the common stock over the measurement period. Expense of $0.5 million, $0.5 million and $0.3 million related to MSUs was recorded in the years ended December 31, 2016, 2015 and 2014, respectively. Activity related to the Company’s MSUs during the year ended December 31, 2016 was as follows:

Exchanged for shares	(13,103	)		(19,656	)
