As discussed in Note 6, in December 2013, the Company issued $86.3 million aggregate principal amount of 2.25% convertible senior notes due 2018 (the “Notes”) in an underwritten public offering. Upon any conversion, the Notes may be settled, at the Company’s election, in cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock. For purposes of calculating the maximum dilutive impact, it is presumed that the Notes will be settled in common stock with the resulting potential common shares included in diluted earnings per share if the effect is more dilutive. The effect of the conversion of the Notes is excluded from the calculation of diluted income (loss) per share because the impact of these securities would be anti-dilutive. The potential dilutive effect of these securities is shown in the chart below:
