Thank you, Ilene, and again, good morning. The second quarter, as Ilene mentioned, is the best in the company's history. It is reflective of the strength of the business model and the company's risk management philosophy and execution. While no business model is immune to the economic ups and downs of the world, our business model is holding up well. As we have discussed in both the year-end and first quarter calls, we expected a few headwinds this year and some tailwinds as well. Our forward-looking guidance incorporated volume growth, increased pricing to cover higher year-over-year input costs and weakening foreign currencies. Since the first quarter call, we have seen a continued decline in currencies and most recently, a major spike in corn prices. We are not changing guidance as we move into the second half. The adjusted earnings per share range remains at $5 to $5.25. Given the economic climate and the volatility in the market, we are pleased to be able to maintain this outlook.
Moving to the second quarter, reported earnings per share were $1.40. Included in this number is approximately $0.16 related to the reversal of a tax asset valuation allowance set up 3 years ago against our South Korean business. At that time, we wrote down the goodwill of our Korean operations to reflect the change in the economics of that business. The write-down was $119 million. We did not recognize the full tax benefit of that write-down, which is in line with the appropriate accounting rules. Following the same rules, we are now required to release the valuation allowance. Obviously, the tax rate for the year and the quarter are impacted by this. Without the valuation allowance and restructuring costs, we are estimating the annual effective tax rate to be between 31% and 33%.
We also announced a business restructuring related to our Kenyan operations. We are closing our plant in Eldoret and will move from a local production model to a distribution/trading model. After an extensive review of the business, we concluded that the ability to generate positive results with a local production model was not feasible. The major challenges were the volatility in raw material sourcing and costs. Given the low barriers to entry, the ability to reprice for this volatility was becoming more and more challenging, hence the decision to restructure our approach. We estimate the total pretax cost to be between $22 million and $24 million. The charge this quarter is roughly $10 million pretax and covers primarily the write-off of assets and some adjustments to the value of working capital. The after-tax impact is $4 million, and the EPS impact is $0.05. The remainder of the charges are expected to occur in the third and fourth quarters. Approximately 75% of the charge is noncash.
Turning back to our financial overview, restructuring and impairment charges related to the National Starch acquisition in the second quarter were approximately $4 million pretax, $2.4 million after tax and worth about $0.03 per share this quarter. These charges are associated with the accelerated depreciation related to the continuing manufacturing optimization in North America that we have discussed previously. We have one more quarter to go on these charges. Of course, those of us who need numbers to balance, there is another $0.01 related to integration costs. The adjusted earnings per share reflecting the above-mentioned items is $1.33 and is the highest adjusted quarterly earnings per share in our history. The other highlight for the quarter relates to the strong cash flow performance. We generated $289 million in cash flow from operations.
Moving to the income statement highlights, we generated $1,635,000,000 in revenues, up $50 million from a year ago or slightly over 3% growth. Gross profit dollars increased by $23 million to reach $295 million, while the gross profit margin increased by 90 basis points to 18.1%. Reported operating income grew $18 million, while the adjusted operating income was up $23 million. Again, the difference between these numbers is the $14 million in restructuring costs and $1 million for integration costs. Reported earnings per share rose $0.39 or 39%, and adjusted earnings per share of $1.33 is up $0.23 per share or approximately 21%. The $50 million increase in revenues for the quarter was the result of strong pricing actions totaling $80 million, while volume growth contributed $42 million. The combination of these 2 more than offset the decline in revenue from weaker foreign currencies of $72 million.
On a regional basis, North America led the way with an 11% increase in net sales. The increase of $97 million was the result of strong pricing, which contributed roughly $56 million, and solid volume growth of 5% or $47 million. The negative impact from currencies was $6 million.
Again, as Ilene mentioned, last year's second quarter included the Argo plant shutdown. I would estimate that a couple of percentage points of the volume are due to the weaker comparative quarter.
Moving on to South America, we see the impact of a significant devaluation of the Brazilian real, estimated at about 23% from the same quarter last year, and about a 9% devaluation on the Argentine peso. Net sales declined roughly $41 million or 11%. The foreign exchange impact was a negative $46 million. The impact from lower volumes was $9 million, and positive pricing contributed $14 million.
As we will see on the operating income slide, the foreign exchange and volume impact was basically muted due to high price/mix and lower corn cost in the quarter. We are managing the foreign exchange headwinds with a combination of pricing and lower corn cost. Asia Pacific was up 3% or $7 million, driven by positive volume of $9 million, and favorable pricing of $6 million more than offset the negative impact of $8 million from foreign exchange. Sales increased roughly $7 million.
EMEA's revenues declined $12 million due to the weaker euro and softening volumes, both the result of the current economic crisis in Europe. The euro declined about 11% from an average last year of $1 -- or $1.44 to the quarter of $1.27. Softer volume negatively impacted revenues by about $5 million, and favorable price/mix contributed a positive $4 million. On an operating income basis, North America was the driver. North America's operating income increased $27 million versus the year-ago period. North America's performance was driven by strong pricing and volume. The pricing was enough to cover the year-over increase in net corn costs. Lower energy and manufacturing efficiencies also contributed to the good results. South America is ably weathering the decline in economic activity and currency devaluations. Between pricing and lower corn costs, the region was able to basically offset the impact of currencies and increased manufacturing costs associated with higher energy and labor inflation. Asia Pacific is also holding its own. Pricing and volume were enough to cover higher manufacturing costs. EMEA, as anticipated, was not able to pass along the devaluation in the euro, and their operating income is down $3 million.
Turning to the earnings per share bridge, we estimate that margin improvement contributed $0.25, and volume, $0.03. This was more than enough to offset the negative $0.08 from foreign exchange. Below the line contribution was $0.03, $0.01 each from lower financing costs, tax rate and share count. We bought back approximately 300,000 shares this quarter and have 3.4 million shares remaining on our stock buyback reauthorization. Weighted average shares in the quarter were 77.9 million versus 78.6 million last year.
On a year-to-date basis, revenues are up $165 million and gross profit increased $21 million. Reported operating income declined by $48 million, while the adjusted OI was up $14 million. The variance was primarily a result of the income of $58 million from the NAFTA settlement in the year-ago period and $4 million higher net acquisition restructuring costs.
Reported earnings per share were $2.61 or a $0.36 decline. On an adjusted basis, EPS was $2.59, an increase of $0.22 when accounting for the NAFTA settlement and change in net acquisition restructuring costs period-over-period. Looking at the net sales variance for the 6 months ended June 30, revenue increased by $165 million or 5%. The year-to-date performance follows the same pattern of strong pricing across the regions, volume growth in North America and Asia Pacific offsetting weakness in South America and EMEA, along with foreign exchange.
On a dollar basis, the price/mix contributed $202 million, volume added $58 million, which was more than enough to offset the negative currency impact of $95 million. Adjusting for onetime items, adjusted operating income rose approximately $14 million. North America was up $26 million; South America, down $4 million; Asia Pacific, up $2 million; and EMEA was down $6 million. Corporate expenses were up $4 million. Restructuring, impairment and integration costs amounted to $21 million.
On a year-to-date basis, the change in adjusted earnings per share was $0.22. Changes from operations contributed $0.12, and nonoperational contributed $0.10, largely from lower financing cost. From a cash flow perspective, the year-to-date numbers look good. Cash from operations was $318 million. Net income and depreciation and amortization generated $313 million. The margin account contributed $56 million and partially offset the increased working capital necessary to support higher sales. Capital expenditures are tracking at $128 million, and we paid $33 million in dividend. The balance sheet remains strong.
Now let's focus on the income statement guidance. Adjusting for the $0.29 of integration and restructuring costs and the $0.16 discrete tax item this year, we are holding guidance at $5 to $5.25 per share. The guidance is based on continued pricing and volume performance in North America and Asia Pacific. We expect to see a continuation of softer volumes in South America and EMEA. The guidance incorporates FX headwinds, and the estimated annual tax rate, excluding discrete items, is expected to be in the range of 31% to 33%. Based on the business performance, we would expect to generate strong cash flow from operations to the tune of approximately $600 million and to spend between $275 million and $325 million on capital expenditures.
The regional outlooks remain fairly consistent, with North America reflecting higher sales and operating income growth coming from pricing, volume and cost efficiencies. Volumes in South America are expected to be softer in the third quarter versus last year and then pick up in the fourth quarter. We expect operating income to be in line with the second half of last year as pricing actions offset higher input costs and foreign exchange headwinds. At the end of the day, volume will be the determinant of success for this region. Asia Pacific is expected to show volume improvement versus last year, led by Thailand and South Korea. Operating income is expected to increase due to volume and pricing actions. EMEA is expected to show modest volume growth. Expected growth in Pakistan will help mitigate the decline in Europe. Foreign exchange will continue to be a headwind. Expect operating income to be in line with the first half of the year.
So as we move through 2012, we expect to continue to manage the challenges of rising input costs and weakening foreign exchange rates with strong pricing actions and modest volume growth. There are a number of pluses and minuses, but we believe we have adequately captured them in the guidance range.
With that, I'll turn the call back to Ilene to wrap up.
