Balfour Beatty ups value of PPP portfolio after review

LONDON (Reuters) - British building group Balfour Beatty said the value of its public-private partnership portfolio had increased by 46 percent to 1.05 billion pounds following a review.

The company, fresh from snubbing a merger proposal from rival construction firm Carillion last week which it said undervalued it, said the review was based on a new valuation methodology reflecting amongst other things improved cash flow and macro-economic assumptions.

Public-private partnerships are infrastructure ventures which are funded by a partnership of government and company funds.

Balfour Beatty is involved in a total of 37 such projects in Britain and 26 in North America including building roads, hospitals, schools and military housing.

The valuation increase announced on Wednesday was driven by a 63 percent rise in its UK portfolio to 801 million pounds.
