Britain's Mothercare to raise equity as part of restructuring plan

* Plans underwritten equity issue

* Also seeking new debt facilities, other capital sources

* To announce plans on Thursday (Adds detail, shares)

LONDON, May 14 (Reuters) - Britain's Mothercare (Other OTC: MHCRF - news) , the struggling mother and baby products retailer, said on Monday it would ask investors for more money as part of a major restructuring it plans to announce this week.

The firm has seen sales and profit hammered by intense competition from supermarket groups and online retailers in its main UK market as well as by rising costs.

Its shares have lost 86 percent of their value over the last year and in April it replaced Chief Executive Mark Newton-Jones with David Wood, a former Tesco (Frankfurt: 852647 - news) executive.

Mothercare said it has been working on a comprehensive restructuring and refinancing package to put the business on a stable and sustainable financial footing.

"We are in the final stages of detailing these restructuring plans alongside new committed debt facilities, an underwritten equity issue and access to other sources of capital," it said in a statement.

Shares (Berlin: DI6.BE - news) in Mothercare fell 5 percent to 19.1 pence by 0919 GMT, valuing the business at just 32 million pounds ($44 million).

Mothercare, which trades from 137 UK stores, said details would be provided on Thursday when it is also scheduled to publish results for the 2017-18 year.

Its statement followed a report in The Telegraph newspaper which said Mothercare was expected to unveil plans for a company voluntary arrangement (CVA) that would enable it to shut stores and secure rent reductions on others.

The CVA route has already been taken this year by fellow retail laggards - fashion retailer New Look, floor coverings group Carpetright (Other OTC: CGHXF - news) and department store group House of Fraser. ($1 = 0.7365 pounds) (Reporting by James Davey; editing by Kate Holton and Susan Fenton)
