​ The Company intends to settle the principal amount of its convertible senior notes in cash and any excess value in shares in the event of a conversion. Accordingly, shares issuable upon conversion of the principal amount have been excluded from the calculation of diluted earnings per share. If the market value of the notes under certain prescribed conditions exceeds the conversion amount, the excess is included in the denominator for the computation of diluted earnings per share using the treasury stock method. For the three months ended September 28, 2019 and September 29, 2018 and the nine months ended September 28, 2019 and September 29, 2018, approximately 0.6 million, 0.2 million, 0.3 million and 0.2 million shares, respectively, were included in the denominator for the calculation of diluted earnings per share. See Note 7, Debt, to the Condensed Consolidated Financial Statements for additional information.
