Mandelbrot, that is massively helpful for me. To me the headings are ambiguous and unclear. I just wanted to take your points to completion for me - no new capital allowances were created in 2011 (i.e. nothing new bought for the property), effectively the only capital allowances I will be using in the year is the 12.5% on capital allowances created in the past (a current balance of say 5k) - lets say the 12.5% this year = 700. Is this 700 what goes into 208 (b). So, 208 (c) for me should only be 700. Maybe my problem is mis-interpretation of what is carried forward to 208 (a) i.e. maybe I do not put in the 5k at all (it is not to be used in a single year).
