Comparission of key ratios for 3 top world publishers

I had to compare the key ratios of the 3 publisher, Random house, Penguin and Hachette livre all in UK. However it seems there is problem with my calculation .
For Hachette, for example I have the asset turnover of the 0.003 that according to my supervisor is impossible!
I would like to have this ratios edited.
thank you
