Current operating income

Highlights by business

Cement

• Sales were stable in the quarter (up 3% like for like) and up 3% in the first-half (up 3% like for like), reflecting volume improvements in emerging markets and new capacities acquired in Brazil, offset by the negative impact of foreign exchange.
• Volumes increased 9% in the quarter (up 6% like for like) and 8% in the first-half (up 5% like for like), with growth driven by the Middle East Africa region and other emerging markets.
• Pricing was below first half 2010 levels, but progressively moved higher compared to fourth quarter 2010.
• Despite the Group's cost reduction program, higher cost inflation and foreign exchange put pressure on results and margins.

Aggregates & Concrete

• Sales moved down 2% in the quarter (up 1% like for like) but were up 3% in the first-half (up 4% like for like) as higher pricing was offset by foreign exchange in the second quarter.
• Current operating income declined in the quarter compared to last year as better pricing and significant cost saving measures could not compensate for lower volumes and higher cost inflation.

Gypsum

• Sales were up 2% in the quarter and up 5% in the first-half due to volume growth.
• Current operating income moved higher in the first-half as market activity improved and strong cost reduction mitigated the impact of cost inflation.
