The review has been launched by Sly Bailey, who joined Trinity Mirror as chief executive earlier this month.
It will also look at possible disposals and delivering more merger benefits across regional and national operations, as the company seeks to maximise profits, according to a report in the Financial Times. It will look at greater integration in distribution, advertising sales and marketing.
Trinity Mirror is due to post its full-year results next week, where it is expected to have pre-tax profits of £150m on revenue of £1.09bn, down 4% from £1.13bn last time.
The company embarked on a price-cutting war with The Sun and Daily Star last year, as it attempted to boost The Daily Mirror's circulation. However, last month sales fell 3% year on year, while The Sun and Daily Star both rose.
The price cuts, part of a £20m revamp of the Daily Mirror, have already been abandoned in most of the UK, although it still sells for 25p in the London area, instead of the usual 32p. The Sun is also continuing to sell at 20p in the Carlton region.
According to the Financial Times, Trinity Mirror will not be likely to name a new finance director in place of Ric Piper, who ended up not joining the company.
