What is the diluted earnings per share for 31 December 20x0?
A. Diluted earnings per share for 31 December 20x0 is MU5.11 calculated as follows [MU15,850,000 ÷ (3,000,000 + 100,000)]
B. Diluted earnings per share for 31 December 20x0 is MU5.22, i.e., {MU15,850,000 ÷ {3,000,000 - [(100,000 x MU0.75) ÷ MU2]}
C. Diluted earnings per share for 31 December 20x0 is MU5.18 {MU15,850,000 ÷ [3,000,000 + 100,000 - ((100,000 x MU0.75) ÷ MU2)]}
C. Diluted earnings per share for 31 December 20x0 is MU5.18 {MU15,850,000 ÷ [3,000,000 + 100,000 - ((100,000 x MU0.75) ÷ MU2)}.
根据企业会计准则第34号——每股收益（2006）中关于稀释每股收益的计算方法，需要考虑稀释性潜在普通股的影响。在这个例子中，由于股份期权的行权价格（MU0.75）低于当期普通股的平均市场价格（MU2），因此需要考虑其稀释性。计算稀释每股收益时，应当假设所有发行在外的稀释性潜在普通股（如股份期权）均转换为普通股。因此，增加的普通股股数为100,000股，这是按照行权价格（MU0.75）和当期普通股平均市场价格（MU2）的比例计算得出的。所以，Diluted earnings per share for 31 December 20x0 应该是MU5.18，这是通过将归属于普通股股东的当期净利润（MU15,850,000）除以计算基本每股收益时普通股的加权平均数（3,000,000股）与因稀释性潜在普通股转换为已发行普通股而增加的普通股股数的加权平均数（100,000股减去差额部分）得出的。
