Schedule of Convertible Senior Notes | The following table summarizes the terms of the 2019 Notes.
| Principal Amount | Coupon Rate | Effective Rate (1) | Conversion Rate (2) | Maturity Date | Remaining Period of Amortization
March 2019 Notes | $ | 143,750 |  | 5.50 | % | 6.25 | % | 55.9411 |  | 3/15/2019 | 2.96 years
August 2019 Notes | $ | 111,000 |  | 5.50 | % | 6.50 | % | 55.9411 |  | 3/15/2019 | 2.96 years
(1) | Effective rate includes the effect of the adjustment for the conversion option (see footnote (2) below), the value of which reduced the initial liability and was recorded in additional paid-in-capital.
(2) | The Company has the option to settle any conversions in cash, shares of common stock or a combination thereof. The conversion rate represents the number of shares of common stock issuable per $1,000 principal amount of 2019 Notes converted. The if-converted value of the 2019 Notes does not exceed their principal amount at March 31, 2016 since the closing market price of the Company’s common stock does not exceed the implicit conversion prices of $18.06 for the 2019 Notes.
