@reacher, I would still respect @hitesh2710 views as it's better to be a bit conservative on the estimates and work as if the EPS is around 22-23. Once FY16 completes, of course, the more EPS the better and market will re-rate then if the EPS is above the estimates.
I think the corporate tax rate is applicable from FY 17 onwards (April 2016?) though not sure on it.
I won't factor in FY 17 yet personally, will do only in April 2016, that's my personal view, though with secular growth companies market tend to price in much of the future ahead itself.
