Thank you, Mary Winn. And thanks for everyone joining the call today. This morning, we announced our results for the second quarter of fiscal 2015. Once again, we delivered strong financial performance for the quarter. I believe we have further opportunity to take significant steps to better execute our initiatives to serve our consumers and build on our strong foundation for future growth.
I am excited to say we have strengthened our leadership team with Jeff Owen, EVP of Store Operations and Jim Thorpe, EVP and Chief Merchandising Officer, rejoining Dollar General. Both Jeff and Jim have a proven record of driving results at Dollar General and know our company and our consumer extremely well. Getting this team back together should strengthen our ability to move at an accelerated pace.
With that, let's now turn to our results for the second quarter of 2015. Second quarter sales increased nearly 8% to $5.1 billion. We received -- we've delivered, excuse me, same-store sales growth of 2.8% for the quarter. Same-store sales started out strong in May with June being weaker and sales strengthening in July. It is my belief that this was reflective of the weak overall U.S. retail sales report for June and mirrors what you have heard from some other retailers.
Sales per square foot reached a record $225. For the 30th consecutive quarter-over-quarter, we increased both our customer traffic and average ticket. Gross margin expanded by 36 basis points to 31.2%, which follows our strong first quarter margin performance. For the quarter, diluted earnings per share increased 14% to $0.95. During the quarter, we returned $265 million to shareholders through the repurchase of 2.6 million shares of common stock and the payment of a quarterly dividend.
Given our performance for the first half of the year, we are reconfirming our full year financial outlook. Our current expectation is that same-store sales will likely be closer to the lower end of our range of 3% to 3.5% growth. EPS remains in the range of $3.85 to $3.95.
We continue to grow transaction and item units in syndicated share data for the quarter. We experienced consistent mid-single-digit share growth in both units and dollars for the 4-, 12-, 24- and 52-week periods.
With that, let me now turn to an update on our key initiatives. As we shared with you last quarter, we are making targeted labor investments to grow market share in a competitive environment while providing for positive financial returns. The labor hour investment in this select group of stores is designed to ensure we deliver on our customers' expectation in more competitive markets to enhance our in-stock position for a more convenient shopping experience. Our goal is to further reduce the truck to shelf time for merchandise in these stores, providing our consumer with the right product, at the right time, at the right price.
For each phase, the store operations team has a specific metric and timetable for determining the financial return criteria for achieving results, based on a similar 2014 test and learn program. Currently, we have completed the first of 3 phases of the labor investments. Our Phase 1 stores received the incremental labor hours during the second quarter. I am pleased to report that our Phase 1 stores are delivering on our return expectations. Specifically, the key metrics of same-store sales, transactions, average basket and consumer satisfaction scores are all showing significant improvement. I believe these strong results are driven by a notably better in-stock position post the incremental store investments. With these solid results, we plan to accelerate our implementation of Phases 2 and 3 in stores in the second half of the year.
The second investment in labor comes from the realignment of our store operations management structure to optimize the scale of our divisions, regions and districts to improve accountability and maximizing training and teamwork, all while driving stronger, more sustainable results. We have reduced the time our district managers spend driving so they can invest more time mentoring and coaching our store managers on developing and strengthening their teams. These changes have been in place since February. We expected that, over time, this would help both our consumer satisfaction and store manager turnover. We are pleased to see signs that this initiative is paying off. Our customer satisfaction scores are improving, and we are approaching our fourth consecutive month of declining store manager turnover rates.
Further, we are moving forward with a number of inventory management initiatives. For example, our sky-shelf program will be completely rolled out across the chain by the end of the third quarter to allow for placement of inventory directly above the respective categories. This allows our teams to get product out of the back rooms to facilitate improved stocking and ultimately, drive labor efficiencies. Already, we are seeing encouraging results with our receiving room inventory down by about 20% based on the most recent store inventories.
During the third quarter, we anticipate concluding our multiyear rollout of our enterprise resource planning software for our supply chain. Our new supply chain solution provided by our vendors, Symphony EYC, is replacing our legacy system, which has limited capabilities to support our growth. This technology platform represents a significant improvement with enhanced integration to allow for demand forecasting from vendor to shelf. Going forward, our new system is scalable to support our growth and configurable to support changes in our business. Over time, we believe this project will benefit our inventory levels at the DCs and in the stores and our allocation of merchandise on a store-by-store basis.
Our overall in-stock position on the shelf should improve as well. This is a significant investment that will allow us to better service our stores and provide much better visibility into our business.
On a combined basis, we believe these labor investments and inventory management initiatives are significant steps to improving our in-stock position, which is a critical component of our overall customer satisfaction and a driver of sales performance.
On the merchandising front, we had positive same-store sales growth across all categories in the second quarter. Growth was generally balanced across consumables and non-consumables. This represents the sixth consecutive quarter for improvement in our non-consumable categories. Strength in consumables was driven by candy and snacks, tobacco and perishables. In addition, we had broad-based strength across seasonal and home. Our ladies and accessory departments within the apparel group continued to exhibit strong performance, comping above the company average.
Affordability continues to play a key role as we expand SKUs across the store at the sweet spot of $1 to $5. For the second quarter, nearly 50% of our consumers' baskets contained at least one item priced at $1, and these baskets grew faster than our overall transactions.
Shrink improvement has been and continues to be one of our largest gross margin opportunities. We remain committed to reducing our shrink at store level. For the quarter, we are extremely pleased with our shrink improvement. This progress was broad-based with shrink declining in 70% of the product departments and approximately 70% of our regions improving year-over-year based on store inventories performed so far this year. Going forward, our teams continue to be focused on leveraging our defensive merchandising tools, technology and training to reduce shrink.
Turning to the second half of the year, including the holiday season. We are capitalizing on our consumer insights to strengthen our merchandising offering across product categories. In turn, this will be supported by a robust print and digital marketing calendar. We continue to capitalize on new ways to wow our consumers. We are focused on expanding high-opportunity categories and giving our consumer the trend-right products she wants at affordable prices.
For instance, we know licensed products resonate with our consumers as they are on trend and communicate value. As a result, we are broadening our reach across categories with more impactful licensed products. At the same time, affordability is as important as ever to our consumers. For 2015, more than 40% of our holiday seasonal assortment is priced at $1.
From a real estate perspective, we remain disciplined and focused on financial returns. We continue to see our new store productivity at around 85% of our comp base, all while driving strong returns. We remain very optimistic about our new store outlook for 2015 and our pipeline is full.
The Dollar General stores in our 3 new states of Maine, Rhode Island and Oregon, continue to ramp up nicely. We have reduced the capital investment required for remodels, while also driving strong sales lifts of 4% to 5% and an improved return on investment in excess of 200 basis points.
In total, the team has already executed more than 1,000 projects across new store openings, remodels and relocations. This represents around 8 projects a day. The real estate team has continued to build upon its progress for the 2016 pipeline. The planned growth in selling square feet of about 7% translates to approximately 900 new store openings. Our development pipeline is over 80% complete for planned 2016 store openings, and we expect to be 100% complete by the fourth quarter. Our strong track record of delivering exceptional returns in our new store program gives us confidence in our model going forward.
Now let me turn the call over to John.
