Risso’s supervisor asks her to upte, of 1 January 2015, a quarterly researreport for Centralino S.p.A., a telecommunications company heauarterein Italy.

So, normalizeEPS is calculateAverage ROE × BVPS = 0.131 × €22.58 = €2.96. 我是用表1求的current BVPS 已知2014的ROE=EPS/BVPS=14.21% ，而2014的EPS=5.64，相除就得到BVPS=ROE/EPS=0.1421/5.64=39.7 另外，想问一下，课件中说averageROE法 乘以的是current BVPS 如果题目给了2015（E）的BVPS可以用吗？还是必须是2014的BVPS
