Blipton Co.

Sir I have attempted the question blipton Co and have subtracted capital allowance from taxable profit and again added after tax (Since 1st year 31 Dec 2009 is investment phase so there won't be any tax) from 1st, 2nd, 3rd and 4th year. So my question is that, is my treatment correct and can u also confirm that negative cash flow in an operating year won't be counted in investment phase instead it will be counted in recovery or return phase?
