Thanks, Rodney, and good morning, everyone. Our identical supermarket sales increased 4.2% in the first quarter, which contributed to net earnings totaling $439.4 million compared to $432.3 million in the same period last year.
Net earnings per diluted share showed strong growth to $0.78 from $0.70 per diluted share last year. Our earnings per share growth was driven by EBITDA being higher than our expectations. Additionally, a tax reserve adjustment helped by about $0.015. FIFO gross margin was 20.7% of sales for the first quarter of fiscal 2012. Excluding retail fuel operations, FIFO gross margin decreased 53 basis points from the same period last year.
We are pleased with this performance, which was consistent with our plan for the quarter. Last year, we saw a very strong gross margin in the first quarter. Kroger recorded a $46 million LIFO charge during the first quarters of both 2012 and 2011.
Operating, general and administrative costs were 15.36% of sales. Excluding retail fuel operations, OG&A declined 27 basis points from the same period last year. Including rent depreciation, it was a 40-basis-point reduction. The benefits of leverage from productivity improvements, outstanding cost control and positive sales more than offset rising health care costs and credit card fees. Additionally, the consolidation of 4 UFCW pension plans in the prior year benefited operating expenses in the first quarter as we anticipated.
Identifying and delivering sustainable operating cost reductions allows us to invest at all 4 keys of our Customer 1st strategy consistently over time. The company's FIFO operating margin, excluding fuel, on a rolling 4-quarters basis decreased 11 basis points. This was a little better than we expected due to the higher EBITDA versus our original expectation that I mentioned a moment ago. We still expect FIFO operating margin, excluding fuel, to slightly increase for the full year of 2012. Additionally, we generated more operating margin profit dollars this year compared to last year.
Turning now to Kroger's retail fuel operations. In the first quarter, our supermarket fuel centers and convenience stores produced positive identical gallon growth. These outlets earned approximately $0.121 per gallon compared to $0.124 in the same quarter last year. The benefit to earnings per share was the same as last year.
Now I'll update you on our financial strategy. During fiscal 2012, Kroger plans to use cash flow from operations to fund capital expenditures, repurchase shares, pay dividends to shareholders and maintain its current debt rating. Kroger repurchased 14.6 million common shares for a total investment of $345.3 million in the first quarter. The Board of Directors have authorized a new $1 billion share repurchase program that replaces the prior authorization which was exhausted on June 12, 2012, just a couple of days ago. Over the last 4 quarters, Kroger has used its strong free cash flow to return more than $1.6 billion to shareholders through share buybacks and dividends.
Capital investment, excluding acquisitions and purchases of lease facilities, totaled $539.1 million for the first quarter compared with $573.1 million for the same period last year. We continue to expect full year capital expenditures to be in the $1.9 billion to $2.2 billion range.
Net total debt was $7.8 billion, an increase of $662.1 million from a year ago. This is primarily the result of debt issued to fund our UFCW pension plan consolidation. On a rolling 4 quarters basis, Kroger's net total debt to adjusted EBITDA ratio was 1.91 compared with 1.79 during the same period last year.
In March, we told you that we expect the external environment to be a little better in 2011. Generally speaking, this has been our experience through the first quarter. We continue to monitor changes in gas prices and inflation. And as the headlines continually remind us, macroeconomic issues will continue to affect consumer sentiment throughout the year. We are confident in our ability to make tactical adjustments as needed to successfully navigate these factors while continuing to deliver on our Customer 1st strategy.
Kroger's long-term business model is to generate earnings -- annual earnings per share growth averaging 6% to 8% plus a dividend of 1.5% to 2% for its shareholder return of approximately 8% to 10%. We expect this total return to compare favorably to the S&P 500 over a rolling 3- to 5-year time horizon.
We continue to expect fiscal 2012 earnings per share growth to be higher than our long-term business model, and our strong first quarter positions Kroger's for an even more robust 2012 than originally expected. Therefore, we've increased our earnings guidance for the first year to -- for the fiscal year to $2.33 to $2.40 per diluted share. The original guidance was $2.28 to $2.38 per share. The increase reflects the strength of the company's first quarter results.
I'd like to share a little bit more about pharmacy's better-than-expected performance, which helped sales as well as earnings in the first quarter. Pharmacy achieved double-digit identical sales, about half due to new Express Scripts business and half from exceptional overall pharmacy performance. Even without Express Scripts, it was an excellent quarter for our pharmacies.
Our ability to project pharmacy performance over the course of the year remains difficult when factoring in the benefit of Express Scripts and prescription drugs coming off patent. This quarter was good, and we were -- and we think we are satisfying new customers who transferred because of Express Scripts.
We continue to expect identical sales to trend down throughout the remainder of the fiscal year as prescription drugs come off patents. For these reasons, we continue to expect identical supermarket sales growth, excluding fuel, of 3% to 3.5%.
As we said at year end, we expect second -- the second quarter growth rate to be in line with our long-term growth rate of 6% to 8%, and the third and fourth quarters will be higher than that. The fourth quarter will also benefit from the 53rd week.
Now I will turn it back to Dave.
