Thanks, Rodney, and good morning, everyone. Our second quarter results demonstrate our ability to deliver for shareholders while we reposition the company for the future through Restock Kroger.
As noted in our press release this morning for the first half of 2018, Kroger's adjusted net earnings per diluted share result was slightly ahead of our internal expectations due to the solid early execution of Restock Kroger, including process changes that led to sustainable cost controls and higher-margin alternative revenue streams. This performance will allow us to continue making incremental investments while delivering on our guidance range for the year.
We also noted that the second quarter adjustment items relate primarily to the change in the market value of Kroger's investment in Ocado securities. Since our investment and partnership announcement in the second quarter, the share price has doubled.
As you know, we accelerated several planned Restock Kroger investments starting in the first quarter and continuing during the second quarter. These include investments in price, especially in support of Our Brands, and in space optimization. Our pricing strategy isn't new. Since 2000, we have invested more than $4.2 billion in lower prices for customers, while also striving to provide the best full-service grocery experience in America.
Even as we pursue our long-term strategy, we always look for ways to bank savings before we make significant investments, as we did in the first half of the year. We noted in June that pull-forward investments in Restock Kroger that began in the last 4 weeks of the quarter and continued space optimization rollout will be headwinds to ID sales in the second quarter. So this effect is not a surprise to us. We expect the headwinds from space optimization during the first half of 2018 to come -- become a tailwind late in the third quarter.
Looking at our ID sales in the second quarter, 20 of our supermarket divisions had positive IDs, demonstrating Restock Kroger is resonating with customers across the company. Several departments outperformed our total ID sales in the second quarter, most notably natural foods, seafood and pharmacy. We also continue to see growth in households during the quarter.
Looking at gross margin, we were pleased to see that our shrink rate continue to improve during the second quarter. The gross margin rate reflects the company's price investments, some rising transportation costs and the growth of the Specialty Pharmacy business. Part of our price investments was to support Our Brands, especially to reduce starting price points. The improvement new movement in the quarter demonstrates these investments are resonating with customers. We intend to continue to invest in price to drive unit growth while also delivering on the bottom line for our shareholders.
OG&A costs increased as a rate of sales driven entirely by higher expense for incentive plans as compared to last year. We continue to face rising credit card fees, especially as more customers shift to using credit cards with higher interchange rates. This is a growing problem, and we are taking steps to address it.
You likely saw the news this summer that our Foods Co supermarket division announced that it would no longer accept Visa credit cards as a form of payment. This is because Visa rates and fees among the highest of any credit card brand. We stopped accepting Visa credit cards to save on the high costs associated with credit card companies' interchange rates and network fees. The savings will be passed along to Foods Co customers in the form of everyday low prices on items shoppers purchase the most.
Foods Co has stopped accepting the cards in mid-August, and we are currently assessing our next steps. We're prepared to expand nonacceptance to other banners if that's what it takes to get a level playing field for negotiated interchange rates.
It's also worth noting that we recently changed our Kroger rewards credit card from Visa to MasterCard. We will continue to aggressively manage OG&A costs and implement new programs to reduce our cost of goods. A big focus continues to be on the store productivity and waste.
We manage our business every day to drive shareholder value. Our investments in Restock Kroger in redefining the grocery customer experience, partnering for customer value and developing talent will be paid for by cost of goods savings, strong ID sales and productivity gains. This is how we will generate $400 million of incremental FIFO operating profit by the end of 2020.
Now for an update on our retail fuel performance during the second quarter. Our second -- our cents per gallon fuel margin was approximately $0.263 compared to $0.217 in last year's second quarter. The average retail price of fuel was $2.85 versus $2.28 in the same quarter last year.
We expect our 2018 tax rate to be approximately 22%. Excluding the 2018 first and second quarter adjustment items, we expect the 2018 rate to be approximately 20%. Favorable tax resolutions with certain states during the quarter benefited adjusted second quarter net earnings by about $0.01 per diluted share.
As previously announced, we're actively exploring strategic alternatives for our Turkey Hill Dairy business, including a potential sale. We want to ensure Turkey Hill has every opportunity to meet its full growth potential. Turkey Hill is a unique CPG food business within Kroger, as it is a strong nationally known brand. Much like our convenience store business, Turkey Hill is such a beloved brand, thanks to the 800 dedicated associates who've contributed to its success.
We remain committed to generating the $6.5 billion of free cash flow by 2020 as part of Restock Kroger. The original amount was $6 billion, and we increased it to $6.5 billion after the passage of the federal tax act. We expect the tax act to reduce cash taxes by about $1.2 billion over the next 3 years. We used $700 million of those savings to fund our investment in Ocado and our merger with Home Chef. On one other note -- one other note to this is we have working capital improvements built into the guidance, and we are off to a great start with a $300 million improvement in net operating capital so far this year.
Kroger's net total debt to adjusted EBITDA ratio on a 52-week basis is 2.59. Our net total debt to adjusted EBITDA ratio target range is 2.3 to 2.5. For the remainder of fiscal 2018, we expect our leverage ratio to remain slightly above the target range, primarily due to increased borrowings to fund the company's merger with Home Chef and investments in Ocado. Kroger remains committed to bringing the leverage ratio back into the target range.
Our financial strategy is to use our free cash flow to drive growth, while also maintaining our current investment-grade debt rating in returning capital to shareholders. We continually balance the use of cash flow to achieve these goals. Over the last 4 quarters, we have used cash to contribute an incremental $1.1 billion pretax to the company-sponsored pension plans and $467 million pretax to satisfy withdrawal obligations to the Central States Pension Fund.
We repurchased 103 million common shares for $2.6 billion, which includes $1.2 billion repurchased with after-tax proceeds from the sale of Kroger's convenience store business unit under a previously announced accelerated stock repurchase plan. We paid $435 million in dividends and invested $2.9 billion in capital. As of the end of the second quarter, we had approximately $546 million remaining under the current share repurchase reauthorization.
We're investing an incremental $500 million in our associates in wages, training and development over the next 3 years through Restock Kroger. This will be in addition to our continued efforts to rebalance pay and benefits, while also focusing on certifications and performance incentives, career opportunities and trainings. In March, we also announced investing a portion of our tax savings in our educational assistance program, Feed Your Future, and an increased 401(k) match for our nonunion associates.
We recently ratified a contract with the UFCW covering Kroger associates in Fort Wayne, and in the Richmond and Hampton Roads areas. We are currently negotiating with UFCW contracts for stores covering associates at Smith’s in Albuquerque and Fred Meyer in Portland. Our objective in every negotiation is to find a fair and reasonable balance between competitive costs and compensation packages that provide solid wages, good quality affordable health care and retirement benefits for our associates.
We continue to strive to make our overall benefit package relevant for today's associates. Our financial results continue to be pressured by inefficient health care and pension costs, which some of our competitors do not face. We continue to communicate with our local unions and the international unions, which represent many of our associates, on the importance of growing our business and profitably, which will help us create more jobs and career opportunities and enhance job security for our associates.
Turning now to guidance for 2018. We continue to expect identical sales growth excluding fuel to range from 2% to 2.5% in 2018. We updated our GAAP net earnings guidance range to $3.88 to $4.03 per diluted share for 2018, from the previous range of $3.64 to $3.79. This increase in guidance is due to the unrealized gain in Ocado shares recorded in the second quarter and does not reflect any ongoing changes in the market value of Ocado shares because those cannot be predicted.
On an adjusted basis, our net earnings guidance range remains $2.00 to $2.15 per diluted share for 2018. We continue to expect capital investments, excluding mergers, acquisitions and purchases of leased facilities to be approximately $3 billion for 2018.
And now I'll turn it back to Rodney.
