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. For the quarter, we delivered an adjusted EPS of $0.44 per diluted share. I'd like to highlight a few areas on our business that were particularly robust.
Our Brands contributed as both a sales driver and a profit leader. The entire Kroger team brought discipline to controlling costs during the second quarter and delivered on our Restock Kroger savings plans. The alternative profit businesses achieved budget, setting us up to deliver our incremental operating profit target for 2019. And our fuel performance was strong, helping mitigate pharmacy gross margin, LIFO and tax headwinds in the quarter.
LIFO charge for the quarter was $30 million compared to $12 million for the same period last year driven by a higher-than-expected inflation in dry grocery, pharmacy and dairy. Our adjusted corporate tax rate for the quarter was 23.9% compared to 18% in the same period last year. These 2 factors combined represented a $0.05 per diluted share headwind in the quarter compared to last year.
As Rodney mentioned, Kroger reported identical sales without fuel at 2.2% during the second quarter, marking our strongest quarter since we launched our transformation plan. Several departments outperformed the company in the quarter, including key beverage categories, produce and natural foods. We were also pleased with top line momentum in our pharmacy business and experienced mid-single-digit increase in script counts. Overall, we are pleased with sales progress in the quarter, and we will continue to work to build on this momentum in the second half of the year.
Adjusted FIFO operating profit for the second quarter was $626 million, an increase of 10.6% compared to the second quarter in 2018. Gross margin was 21.9% of sales for the second quarter. FIFO gross margin, excluding fuel, decreased 29 basis points from the same period last year primarily driven by industry-wide lower gross margin rates in pharmacy and continued growth in our specialty pharmacy business. Retail supermarkets, excluding fuel and retail pharmacy, saw 12 basis points of gross margin investment.
Based on the needs of the business, we are focused on balancing margin investments and capturing cost of goods, sourcing savings and operational efficiencies to offset these investments. As a great example of this focus, our associates have done an impressive job managing shrink, which improved in the second quarter compared to last year. This represents the eighth consecutive quarter of year-over-year shrink rate improvement.
OG&A cost as a rate of sales, excluding fuel and adjustment items, decreased 14 basis points. This was achieved through continued focus on execution of Restock Kroger initiatives that drive administrative efficiencies, store productivity and sourcing cost reductions.
We always look for opportunities to improve free cash flow and ROIC, important metrics to Kroger shareholders. During the quarter, we accepted a substantial offer to sell an unused warehouse that had been on the market for some time. Kroger used the gain from this transaction as an opportunity to contribute a similar amount into the UFCW company pension plan, helping stabilize associates' future benefits. The net impact of these transactions to EPS growth was neutral.
As we have previously shared, fuel is an important part of our strategy to drive customer engagement, and our loyal customers continue to receive hundreds of millions of dollars in fuel rewards each year in the form of price discounts at the pump. The average retail price of fuel was $2.71 this quarter compared with $2.85 in the same quarter last year. Retail fuel profit came in above our expectations for the quarter. Our cents per gallon fuel margin in the second quarter was $0.35 compared to $0.26 in the same quarter last year. Fuel is a great example of Kroger sourcing teams continuing to improve buying practices. This allowed us to achieve improvement in fuel cost of goods in the second quarter. We now expect fuel to be less of a headwind in the second half of the year than originally anticipated.
Alternative profit streams are on track to contribute an incremental $100 million in operating profit in 2019. Media and Kroger Personal Finance will be the primary drivers of growth this year.
Kroger Precision Marketing continued to build momentum in the quarter, increasing engagement to over 300 consumer packaged goods companies and experienced a 90% retention rate along with significantly higher spend. Kroger Personal Finance also saw growth in line with expectations during the quarter as we successfully expanded the number of customers and the frequency with which customers utilize these products.
And now for an update on labor relations. We ratified the new labor agreement with the UFCW covering associates in Fort Wayne, Indiana; Louisville, Kentucky; and Nashville, Tennessee, during the second quarter. We also reached a tentative agreement with the UFCW covering 17,000 associates in our Ralphs division in Southern California earlier this week. We are currently negotiating with the UFCW for contracts covering store associates in Las Vegas, Memphis, Portland and Seattle. 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 to 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 in a profitable way, which will help us create more jobs and career opportunities and enhance job security for our associates.
Our financial strategy is to use our strong free cash flow to drive growth while also maintaining our current investment-grade debt rating and returning capital to shareholders. We actively balance the use of cash flow to achieve these goals. We committed to prioritize free cash flow to reduce the company's net total debt to adjusted EBITDA ratio to within our target range of 2.3 to 2.5. Over the last 12 months, net total debt has reduced by $1.3 billion, and Kroger's net total debt to adjusted EBITDA ratio is 2.46 for the second quarter of 2019 compared to 2.59 a year ago. We remain committed to our target net total debt to adjusted EBITDA range, and as we start to operate consistently within that range, we will explore options for returning additional capital to shareholders. Earlier this year, Kroger increased the dividend by 14%, marking the 13th consecutive year of dividend increases.
Turning now to guidance for 2019. We continue to expect identical sales growth, excluding fuel, to range from 2% to 2.25% in 2019. We continue to expect adjusted net earnings to range from $2.15 to $2.25 per diluted share and adjusted FIFO operating profit to range from $2.9 billion to $3 billion for 2019. We are pleased with our second quarter progress and are maintaining full year guidance to 2019.
With pharmacy gross headwinds expected to continue in the second half of 2019 and as we lap a particularly strong OG&A performance in the third quarter of 2019 -- 2018, we now expect EPS to be flat in the third quarter of 2019. In the fourth quarter, we expect double-digit EPS growth as we lap discrete items from prior year and continue to build strong momentum with our alternative profit streams.
I'll now turn it back to Rodney.
