Boral announces on-market share buy-back

Boral Limited (ASX: BLD) has today announced its intention to commence an on-market share buy- back program for up to 5 per cent of the Company's issued capital or approximately 39 million ordinary shares over the next 12 months.
This follows the Company's successful completion of a number of transactions over the last 12 months which have reduced the Group's net debt, positioning the Company with a sound balance sheet and cash position to conduct an on-market share buy-back.
Boral's CEO and Managing Director, Mike Kane said "this buy-back reflects Boral's commitment to efficient capital management and delivering improved returns to shareholders. At the same time, we are maintaining flexibility to respond to changes in market conditions and to take advantage of appropriate growth opportunities that may present in the future."
Based on the Company's closing share price of $6.02 on 17 March 2015, 5 per cent of Boral's issued share capital or around 39 million ordinary shares would represent a buy-back program of approximately $236 million.

An Appendix 3C in respect of the on-market share buy-back is attached.
