Thank you, Paul. Sales in the second quarter of $484 million were 19% higher than the previous year. Lochinvar, which we acquired in August last year, added $55 million and sales of A. O. Smith-branded products in China grew 17% to $106 million. Earnings of $35 million or $0.75 per share were 47% higher than last year, when the benefit from several onetime items which collectively resulted in a net gain of $0.11 per share in 2011 are excluded from the comparison. Sales in our North America segment of $366 million increased 21% over last year. This segment includes our U.S. and Canada water heater and boiler businesses.
In addition to incremental sales of $53 million from Lochinvar in North America, we experienced higher volumes of residential and commercial water heaters in the U.S. as a result of the pre-buy by our wholesale customers, in advance of a June price increase. We experienced higher commercial volumes in the second quarter than any other quarter in the last 4 years. Lower sales of tankless products in the U.S. and water heaters in Canada partially offset higher U.S. volumes. While it is difficult to calculate, we estimate the pre-buy impacted revenues in the second quarter by approximately $15 million and its impact to earnings was between $0.05 and $0.06 per share. The results of our China, India and Europe water heating businesses and our water treatment business in Asia are captured in our Rest of World segment. Segment sales of $127 million increased 15% compared with last year, due to a 17% increase in sales of A. O. Smith-branded products in China.
Our retail expansion is on track, our premium brand continues to gain market share and our newer products, most notably gas tankless, are growing faster than our overall business.
North America operating earnings of $51 million were $16 million higher than last year, excluding onetime items. The Lochinvar acquisition added $10 million to operating earnings and the effect of higher U.S. water heater volumes from the pre-buy also contributed to the year-over-year increase. Last year, the segment benefited from a $3 million net gain resulting from a settlement with a component supplier and an increase to the warranty reserve. As a result of higher volumes, in particular higher-margin commercial water heaters and Lochinvar's performance, the segment's operating margin improved significantly to 14% in 2012.
Rest of world operating earnings of $12 million improved 12% compared with last year, driven by higher China sales, which were partially offset by larger losses in India, primarily due to the weaker rupee and cost to build our brand and expand our product offering in the region. As a result, operating margin fell slightly to 9.7%. Our corporate and other expenses were $11 million, an improvement compared with last year, primarily due to interest earned on our cash, which was partially offset by higher pension cost. Total operating profit, excluding the RBC share gain in 2011 and onetime items, improved 52% to $53 million.
Cash provided by continuing operations was $30 million at the end of the second quarter compared with cash used by operations of $105 million last year. 2011 cash flow through June included an approximately $150 million after-tax contribution to our pension plan.
Our liquidity position and balance sheet remain strong. Our debt-to-capital ratio declined to 20% compared with 30% at the end of 2011. We have sizable cash balances located offshore, primarily related to the sale of electrical products and our net cash position was in excess of $150 million at the end of June. We project our cash flow from operations for 2012 to be between $155 million and $165 million. Our capital expenditures are expected to be $75 million to $80 million, which includes approximately $30 million for capacity expansion in China to meet growing demand for our water heaters. Our depreciation and amortization expense is expected to be $55 million this year.
I will now turn the call back to Paul, who will summarize our outlook and acquisition strategy. Paul?
