Thanks, Rodney, and good morning, everyone.
We are very pleased with our first quarter ID sales and earnings results. We did slightly better than our internal expectations. We completed the sale of our convenience stores business unit. And as Rodney said, we had one of the best cost control quarters in a long time due to implementing process changes.
This is important because over the next 3 years, Restock Kroger will be fueled by cost savings that we will invest in associates, customers and our infrastructure. Our goal is to continue generating shareholder value even as we make these strategic investments to grow our business.
We expect Restock Kroger to generate $6.5 billion of free cash flow over the next 3 years. This is before dividends and considers the benefit of the tax plan.
We've already re-prioritized the way we will invest capital over the next 3 years by both reducing the amount we spend and optimizing our capital allocation process. We now look first for sales-driving and cost savings opportunities across both brick-and-mortar and digital platforms. Second, we will continue to make sure our logistics and technology platforms keep pace with and scale these demands through continued investment. Finally, we will allocate capital to storing activity. This process has allowed us to use less free cash flow for capital investments. Our investment in Ocado is a great example of what's possible of our new approach to investing capital.
We continue to aggressively manage OG&A costs and implement new programs to reduce our cost of goods sold. A big focus continues to be on store productivity and waste. Our teams controlled shrink well in the first quarter. As we've said before, we won't leave a $0.01 on the table as we seek to reinvest savings to grow our business.
We plan to generate $400 million in incremental FIFO operating profit through 2020. We are taking advantage of the lower federal taxes under the Tax Cuts and Jobs Act to pull investments forward into 2018 so we can move even faster on Restock Kroger than originally anticipated.
Our pull-forward investments in Restock Kroger began in the last 4 weeks of the first quarter. While the incremental 401(k) contribution match investment was retroactive to the first of the year, costs to support our new associate education program, Feed Your Future, had not begun in earnest. Our investments in wages will roll in as contracts are negotiated and the education payments will occur over time as associates take advantage of the opportunities to further their education.
We will make investments for the rest of the year to drive our strategy and keep prices low to retain our customers. As a reminder, since 2000, we've reduced prices to our customers by over $4 billion. We intend to continue investing in price to drive unit and ID sales growth while delivering on bottom line for our shareholders.
We manage our business every day to drive shareholder value. Our investments in Restock Kroger in defining the customer grocery 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 precisely where the incremental FIFO operating profit will come from over the next 3 years.
For ID sales, we're pleased with our result for the first quarter. Several departments outperformed the company in the first quarter, most notably meat, seafood and our floral department. Natural foods continued to generate strong double-digit growth in the first quarter. And during the quarter, we saw growth in households and loyal households as well as unit growth.
As noted in our press release this morning, we reported identical supermarket sales without fuel of 1.4%. This result was aligned with our internal expectations for the quarter.
When calculating identical sales to be more inclusive of all company business units, including Kroger Specialty Pharmacy and ship-to-home solutions, our ID sales without fuel were 1.9% in the first quarter. We intend to use this calculation going forward as it presents a comprehensive view of our performance as we redefine the grocery customer experience and is therefore a more appropriate measure of our performance. We've also looked at what others include in their ID calculations and have taken this step to be more consistent with how our peers report.
Our space optimization work is right on plan. We have about 30% of our planned 600 stores completed for 2018. Space optimization will continue to be a headwind to ID sales until late third quarter. By then, we will have more stores completed and maturing than in process or not yet started, which is why it will start to be a benefit to sales later in the year.
Retail perform -- retail fuel performance during the quarter was good again. Our cents per gallon fuel margin was $0.187 compared to $0.171 in last year's first quarter. The average retail price of fuel was $2.65 versus $2.28 in the same quarter last year. This includes convenience stores for the period prior to the divestiture.
In April, we completed the sale of our convenience store business unit for $2.15 billion. After tax proceeds, we'll total $1.7 billion. We are returning a significant amount of the capital to shareholders through our $1.2 billion accelerated share repurchase program and we used the balance of the after-tax proceeds to lower our net total debt-to-adjusted EBITDA ratio compared to the end of fiscal 2017.
Kroger's net total debt-to-adjusted EBITDA ratio increased to 2.43 on a 52-week basis. Our net total debt-to-adjusted EBITDA ratio target range is 2.3 to 2.5x. We expect our net total debt-to-EBITDA -- our net total debt-to-adjusted EBITDA ratio to increase throughout the year due to increased borrowings to fund our investment in Ocado, our planned merger with Home Chef and tax payments related to the gain from the sale of our convenience store business unit.
Our financial strategy is to use our free cash flow to drive growth while also maintaining our current investment grade debt rating and returning capital to shareholders. We continually balance the use of cash flow to achieve these goals.
Over the last 4 quarters, we used cash to contribute an incremental $1.2 billion pretax to company-sponsored pension plans and $467 million pretax to satisfy withdrawal obligations to the Central States Pension Fund; repurchased 110 million common shares for $2.7 billion, which includes $1.1 billion repurchased through the accelerated stock repurchase plan; paid $442 million in dividends and invest $3 billion in capital. At the end of the first quarter, we had approximately $546 million remaining under the March share repurchase authorization. Purchases under the ASR will be completed no later than July 6.
We are 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 training.
We have several major negotiations in 2018, including contracts with the UFCW for store associates at Smith's in Albuquerque, Fred Meyer in Portland and Kroger stores in Richmond and Fort Wayne. Our objective in every negotiation is to find a fair and reasonable balance between competitive costs and a compensation package to provides 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, 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 expect identical sales growth, excluding fuel, to range from 2% to 2.5% in 2018. This reflects our updated definition of identical sales and is supported by an expectation for identical supermarket sales that is the same as our original guidance for the year. To be clear, if we hadn't updated the ID sales definition, we would have confirmed our original guidance for the year this morning.
We have raised the low end of our net earnings guidance range to $3.64 to $3.79 per diluted share for 2018. The previous GAAP range was $3.59 to $3.79. On an adjusted basis, we raised the low end of our net earnings guidance range to $2 to $2.15 per diluted share compared to $1.95 to $2.15 previously.
We feel very good about the year. We planned for the first quarter to be our strongest EPS quarter, which creates a tailwind for the investments we plan the rest of the year. Our first quarter was a $0.10 outperformance over the consensus forecast. And as I said earlier, it was also a little better than our internal expectations.
Looking at the consensus forecast through the remainder of the year, we believe the second and fourth quarters are a little high compared to our own expectations and the third quarter looks reasonable. I've taken the unusual step of commenting on this because if you simply add the $0.10 to your forecasts for the year, that would put the consensus above the high side of our guidance range.
We're off to a great start to 2018 and are on pace to deliver our $2 to $2.15 net earnings per diluted share guidance range for the year. We continue to expect capital investments, excluding mergers, acquisitions, and the purchases of leased facilities, to be approximately $3 billion for 2018. And finally, we expect our 2018 tax rate to be approximately 22%.
And now, I'll turn it back to Rodney.
