The amount requested for 2012 is £29,400,000, payable to Williams Grand Prix Engineering Limited's Barclay's bank account no. 00968277, sort code 20-01-09. Details of Williams VAT registration no. (GB 100 1901 88) and company no. (1297497) included in the invoice are correct.
According to Williams F1 profit & loss account made up to end 2010, the company had a turnover of some £91 millions, while reporting a profit of some £6 millions. Williams F1 carries losses of some £88 millions. Against these numbers, the £29.4 millions gotten from PDVSA seem like Williams F1 best deal ever, that's roughly a third of 2010's turnover right there. The amount shown in the invoice -payable for 2012- corresponds with the one detailed in the sponsorship contract between Williams F1 and PDVSA.
