Yorkshire Post publisher Johnston Press expects full year results to be 'satisfactory' as it offsets a worse than expected decline in ad revenues with increased cost savings.The group, which also publishes the Scotsman, said total advertising in the second half of the year to date on a like-for-like basis fell 5.4% compared to a 6.3% decline in the first half.Johnston said the decline in print advertising revenues excluding recruitment in the second half to date is 2.5%, with the decline in recruitment advertising in the same period being 29.1%. In the last 18 weeks, public sector sourced advertising has been particularly difficult, it added. Its recovery has been held back by dwindling recruitments ads and a decline in public sector advertising following cuts by the government.Total annual cost savings are expected to be over £20m and net debt should decline £13m to £388m at the end of October.
