I do not think Tax law has the retrospective effect way back to Year 1986. It could create lots of havoc.
Maybe only restrict to year 2008 and forward.
The Deferred Tax comes about because you need to depreciate let say your Ind Plants at 4% a year under the accounting rule ( over the Lifespan of an asset let say over 25 years ), but disallowed as expense for TAx Computation ( allowance abolished in year 2008 )
Which means the diff between the two ( timing difference ) would be created under the deferred tax under the requirement of FRS 112 accounting standard ( deferred tax treatment ).
The RT (FRS 112 ) always relates to future FS , seldom applicable for past events ( IF ANY ).
let say you defer a project now meaning it is to be carried out in the future , not related to the past in that sense.
Just guessing only cos no access to their accounts.
Correct me if I am wrong.
Investopedia explains Deferred Tax Liability
Because there are differences between what a company can deduct for tax and accounting purposes, there will be a difference between a company's taxable income and income before tax. A deferred tax liability records the fact that the company will, in the future, pay more income tax because of a transaction that took place during the current period
Think only those familiar with UK tax law can advice (too bad I am not).
My guess, Wessex accumulated a lot of unabsorbed IBA (Industrial Building Allowance) for their plants (because their plant not come cheap), and for years they don't have enough profit to set off the allowance. Then the IBA brought forward if consider tax asset to be set off against future profit arise from operation. Then come the abolition, the tax asset become worthless overnight, thus they have to create a tax charge to set off the asset, resulting in massive increase of tax payable for the quarter (but no cash changed hands, rest assure), balance sheet take a beating because the tax asset impairment, but the damage is mostly on paper only.
Only those insider (HQ & Wessex finance department) know best, I can only make a wild guess
