LONDON (Reuters) - Books are covered for an accelerated bookbuild by CRH to help fund the Irish building supply group's acquisition of assets from cement firms Holcim (>> Holcim Ltd) and Lafarge (>> LAFARGE), a source familiar with the matter said on Monday.

CRH said that it was selling around 9.99 percent of its current issued share capital, or 74,039,915 shares, to help fund the 6.5 billion-euro ($7.36 billion/£4.31 billion) purchase.

The share sale is being led by UBS (>> UBS AG). JPMorgan (>> JPMorgan Chase & Co.), Merrill Lynch (>> Bank of America Corp) and J&E Davy are joint bookrunners.
