        In January 2015, we issued and sold in a public offering an aggregate of 2,645,000 shares of our common stock at $50.00 per share, which included 345,000 shares that represented the full exercise of an option to purchase additional shares granted to the underwriters in connection with the offering. This public offering resulted in $124.1 million of net proceeds, after deducting underwriting discounts and commissions and other offering expenses payable by us. At December 31, 2014 we capitalized $0.1 million of costs related to expenses incurred in this public offering that will be recorded to APIC when the offering closes, which are included in other long-term assets.
