​ The fair value of the 1.25% Convertible Senior Notes due 2020 (the “2020 Notes”) is based on data from readily available pricing sources which utilize market observable inputs and other characteristics for similar types of instruments, and, therefore, is classified within Level 2 in the fair value hierarchy. Prior to May 14, 2014, the 2020 Notes were not convertible except in connection with a make-whole fundamental change, as defined in the indenture. Beginning on, and including, May 15, 2014, the 2020 Notes are convertible prior to the close of business on the business day immediately preceding May 15, 2020 only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on March 31, 2014 (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the 2020 Notes on each applicable trading day; (ii) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of the 2020 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the 2020 Notes on each such trading day; or (iii) upon the occurrence of specified corporate events. On or after May 15, 2020 until the close of business on the second scheduled trading day immediately preceding the relevant maturity date, the 2020 Notes are convertible at any time, regardless of the foregoing circumstances. Upon conversion we will pay or deliver, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at our election. On April 1, 2020, the 2020 Notes became convertible through at least June 30, 2020, based on meeting the conversion criteria related to the sale price of our common stock during the calendar quarter ended March 31, 2020 as described in (i) above. The 2020 Notes are reflected in current liabilities on the condensed consolidated balance sheet as of March 31, 2020 due to their maturity date of November 15, 2020, unless earlier purchased or converted.
