Sales development and financial results

Sales volumes for cement, aggregates and concrete slightly declined in the quarter and year-to-date. For cement, sales volumes decreased 3% in the quarter and 1% year-to-date, reflecting divestments and volume declines primarily in Western and Central and Eastern Europe that were partially offset by improvements in North America and Asia. Aggregates sales volumes declined by 1% in the quarter and 2% year-to-date, reflecting lower construction activity in Western Europe. Concrete volumes declined by 7% for both periods due to the sale of US readymix assets in the third quarter 2011, creating a higher base comparison. On a like-for-like basis, readymix concrete sales volumes were stable.

Consolidated sales moved higher, up 5% for both periods, supported by successful price actions to respond to cost inflation across all of our product lines, higher cement volumes in North America and Asia, and favorable foreign exchange.

EBITDA improved for the quarter and year-to-date, up 8%. Double digit EBITDA increases in Middle East and Africa, Latin America, Asia, and North America supported this growth. Declines occurred in Western and Central & Eastern Europe due to the impact of poor weather conditions in the early part of the year, €51 million of lower proceeds from the sale of carbon credits in the first-half compared to last year, and a challenging economic environment. Overall, cost reduction actions contributed €170 million to the results for the first-half.

Net Income Group Share declined to €57 million in the quarter and to €13 million for the first-half. The decrease was primarily due to a €200 million second quarter pre-tax impairment charge on Greek assets resulting from the sustained downturn in economic conditions. In addition, the Group recorded €54 million of pre-tax restructuring charges in the quarter (€148 million in the first-half) as part of the implementation of the Group's cost savings program.

Net debt declined by €1.7 billion relative to June 2011 and moved higher compared to year-end 2011 due to normal seasonal working capital needs and exchange rates.

Investments, divestments and liquidity

Investments totaled €298 million for the first-half 2012, down from €566 million in the first half 2011.

• Sustaining capital expenditures remained stable at €110 million versus €122 million in 2011.
• Internal development capital expenditures and acquisitions declined from €444 million in the first-half 2011 to €188 million in the first-half 2012.

Lafarge received €72 million in cash for divestments in the first-half 2012, including sales of minority stakes, and plans to divest more than €1 billion in 2012.

As of June 30, 2012, Lafarge SA had €3.4 billion in undrawn committed credit lines, with an average maturity of about 3 years, in addition to €2.6 billion of cash on hand.
