Analyst · Barclays
Thanks, Rodney, and good morning, everyone.
Our core business was strong in the third quarter. We are very pleased with our ID sales exceeding 1% in the third quarter. We're especially happy to see the very strong performance in our fresh departments. The results in produce and meat were terrific and we continue to see double-digit growth in natural foods. Our ID sales results were driven by both higher spend per unit and strong growth in the number of households. Total visits continue to grow throughout the quarter and our market share was up. Our business is gaining momentum and our customers are recognizing the investments we are making.
We noted at our investor conference that over the next 3 years, Restock Kroger will be fueled by $9 billion in capital investments, cost savings and free cash flow. We recognize that in order for -- in order to be there for our customers today and, more importantly, to be where they are going into the future, we need to make investments more aggressively and faster than ever before.
We've already prioritized the way we invest capital by both reducing the amount we spend and optimizing our capital allocation process. We now look first for sales-driving and cost savings opportunities through both brick-and-mortar and digital platforms. Second, we will continue to make sure our logistics and technology platforms keep pace with and scale to those demands that were created through these investments. Then finally, we will allocate capital to storing activity. This process has allowed us to use less free cash flow for capital investments.
As Rodney said earlier, we are aggressively managing OG&A costs and implementing new programs to reduce our cost of goods sold. One example is our recent decision to require on-time and in-full delivery from suppliers. We're implementing penalties when scheduled deliveries are missed within a designated window. Over time, this will help keep costs down by ensuring more predictable operations, but more importantly, it will ensure that we have the products in our shelves that our customers want and when they want them.
We expect Restock Kroger to generate $400 million in incremental operating profit margin over the 3 years from 2018 to 2020. We also expect to generate more than $4 billion of free cash flow after dividends over the next 3 years. Our goal is to continue generating shareholder value even as we make strategic investments to grow our business.
Fuel performance was also outstanding in the quarter. Our cents per gallon fuel margin was approximately $0.249 compared to $0.179 in the same quarter last year. The average retail price of fuel was $2.46 versus $2.17 in the same quarter last year. This, along with our store -- our strong core business results, demonstrates the diversity of our earnings.
The fuel performance in the quarter also created the opportunity for us to make an incremental $111 million contribution into our UFC Consolidated Pension Plan. Funding these obligations proactively over time demonstrates our ability to meet our commitment to protect employee pensions while simultaneously delivering value for shareholders.
As you know, we announced last month our intention to explore strategic alternatives for our Convenience Store business, including a potential sale. This was a result of a review of assets that are potentially of more value outside the company than as part of Kroger. This process is ongoing and there has been a high level of interest.
As we stressed last month, our Convenience Store management and associates are an important part of our success. We value what they do and thank them for continuing to put our Customer 1st everyday as we conduct this evaluation.
Over the last 4 quarters, we used cash to contribute an incremental $1.1 billion to company-sponsored pension plans, repurchased 59 million common shares for $1.7 billion, paid $446 million in dividends and invest $2.9 billion in capital. Our financial strategy is to use our financial flexibility to drive growth while also returning capital to shareholders and maintaining our current investment-grade debt rating. We continually balance the use of cash flow to achieve these goals.
As of the end of the third quarter, our current share repurchase authorization had approximately $590 million remaining and return on invested capital for the third quarter on a rolling 4 quarters basis was 12.31%.
Now, I'm going to spend a lot more time talking about pensions this quarter than I normally would. This is driven by not only what we've done this quarter, but also what we've been doing over the past several years.
About a decade ago, we identified a great amount of exposure on pension plans and recognized then that we would need to begin addressing that exposure like we would any big endeavor, one step at a time. Our efforts began in earnest in 2011 when we negotiated and created the UFCW Consolidated Pension Plan. The keys for us were capping prior service costs, negotiating a new benefit accrual going forward, consolidating 4 plans into one and sharing both professional and more efficient management of the assets going forward. We agreed to plan -- to fund the plan over 5 years, but elected to fund it in January of 2012. This arrangement reduced Kroger's annual multiemployer pension expense and skewed -- secured the pension benefits for tens of thousands of Kroger associates.
Including this agreement, we have since made more than $2.3 billion in payments and funding commitments with 2 objectives in mind: One, to address the underfunding in the company-sponsored pension plans; and 2, to address the liabilities of various troubled multiemployer pension plans. We have adopted this approach in a low-interest rate environment to provide greater stability for the pension benefits earned by thousands of Kroger associates and retirees and to manage this liability proactively or, frankly, to avoid kicking the can down the road.
We have said for some time that we expect our net total debt-to-adjusted EBITDA ratio to grow. This is because we are bringing an off-balance sheet item onto our balance sheet or funding an obligation already on our balance sheet. As a result, we are updating our target range for this ratio to 2.2x to 2.4x. These obligations, whether recorded on or off Kroger's balance sheet, have generally been considered when our credit profile's been reviewed, but since they weren't funded, did not get picked up in our net total debt-to-adjusted EBITDA ratio. Our current result of 2.57x is above this range. We expect to use free cash flow and potential proceeds from the sale of assets to get us back in the range.
Protecting associate and retiree pensions is one significant way that we take care of our associates. Another is hiring and job creation. Kroger is currently hiring to fill 14,000 part-time and seasonal jobs. This is in addition to the nearly 10,000 permanent jobs we've already created in 2017. Through Restock Kroger, we plan to invest an incremental $500 million in human capital in wages, training and development over the next 3 years. 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.
On the labor relations front, we recently ratified an agreement with the UFCW for store associates in Charleston, West Virginia and we are currently negotiating an agreement with the Teamsters for the master agreement. Our objective in every negotiation is to find a fair and reasonable balance between competitive cost and compensation packages that provide solid wages, good quality, affordable health care and retirement benefits for our 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 growing it profitably, which will help us create more jobs and career opportunities and enhance job security for our associates.
Turning now for our guidance for the fourth quarter of '17 and all of '17. We expect fuel margins to moderate in the fourth quarter and we're already seeing that quarter-to-date. We expect fourth quarter identical supermarket sales growth exceeding -- excluding fuel, to exceed 1.1%.
We confirmed our 2017 net earnings guidance for 53 weeks of $1.74 to $1.79 per diluted share and our adjusted net earnings guidance range of $2 to $2.05 a share. Both our GAAP and adjusted net earnings per diluted share guidance includes the effect of the hurricanes. The low end of this range is $0.04 above where industry analyst consensus forecast had been, demonstrating Kroger's ability to deliver shareholder value in a dynamic transition year.
Our LIFO expectation has been lowered to $60 million from $80 million and we expect capital investments, excluding mergers, acquisitions and purchases of leased facilities, to be approximately $3 billion for 2017.
Before I turn it back to Rodney, I want to note that in the 8-K we filed earlier today, we reconfirmed our early thoughts on 2018. Rodney?
