Barbara Rentler
Analyst · the SEC.
Now I'd like to turn the call over to Barbara Rentler, Chief Executive Officer
Good afternoon.
Joining me on our call today are Michael O'Sullivan, President and Chief Operating Officer; Gary Cribb, Executive Vice President, Stores and Loss Prevention; John Call, Executive Vice President, Finance and Legal; Michael Hartshorn, Group Senior Vice President and Chief Financial Officer; and Connie Kao, Vice President, Investor Relations.
We'll begin our call today with a review of our fourth quarter and 2017 performance, followed by our outlook for 2018. Afterwards, we'll be happy to respond to any questions you may have.
As noted in today's press release, despite our own difficult multiyear comparison and a very competitive retail climate, sales and earnings were well ahead of our expectations for both the fourth quarter and the full year. We are pleased with these results, which reflect our ongoing success in delivering broad assortments of compelling bargains to today's value-driven shoppers.
Earnings per share for the 14 weeks ended February 3, 2018, were $1.19, up from $0.77 in the 13 weeks ended January 28, 2017. For the 53 weeks ended February 3, 2018, earnings per share grew to $3.55 compared to $2.83 in the 52 weeks ended January 28, 2017. Both the quarter and fiscal year include a per share benefit of approximately $0.10 from the 53rd week and $0.21 from the recently enacted tax reform legislation.
Excluding these items, earnings per share on a 52-week basis for both the 2017 fourth quarter and fiscal year periods grew 14% over the prior year. Net earnings for the 2017 fourth quarter were $451 million, up from $301 million in the prior year. Fiscal 2017 net earnings grew to $1.4 billion compared to $1.1 billion in fiscal 2016.
Total sales for the 14 weeks ended February 3, 2018, grew 16% to $4.1 billion with comparable store sales for the 13 weeks ended January 27, 2018, up 5% on top of a 4% increase in the prior year. For the 53 weeks fiscal year ended February 3, 2018, sales increased 10% to $14.1 billion with same-store sales for the 52 weeks ended January 27, 2018, up 4% versus the 4% increase in 2016. For the fourth quarter, sales trends at Ross were fairly broad-based across all major merchandise categories with Children's performing the best. Geographically, Florida was the strongest region.
Our fourth quarter operating margin of 14.6% was up 95 basis points from last year. This improvement was mainly driven by strong merchandise margin and expense leverage from solid gains in same-store sales as well as the impact of the 53rd week. For the full year, operating margin increased 50 basis points to a record 14.5%. dd's DISCOUNTS' customers also continued to respond positively to its merchandise assortments, leading to another quarter and year of robust gains in both sales and operating profits.
As we ended 2017, total consolidated inventories were up 9% over the prior year with packaway levels at 49% of the total, similar to last year. As planned, average in-store inventories were up 1%. As noted in today's release, we plan to make competitive wage and benefit-related investments. These include raising our minimum wage to $11 an hour, providing onetime bonuses for eligible hourly and store associates and improving our paid leave programs. We believe these actions will allow us to continue to attract and retain a talented and growing workforce of over 82,000 associates who have been critical to our past performance and will be key to our future success.
Further, our board recently approved an increase in our stock repurchase authorization for 2018 to $1,075,000, 000, up from the previous $875 million. The board also approved a higher quarterly cash dividend of $0.225 per share, up 41% over the prior year. The increases of our shareholder payouts for 2018 reflect the current strength of our balance sheet and our ongoing ability to generate significant amounts of cash after funding growth and other capital needs of the business. We have repurchased stock as planned every year since 1993 and raised our cash dividend annually since its inception in 1994. This consistent record also reflects our continuing commitment to enhancing stockholder value and returns.
Now Michael Hartshorn will provide further color on our 2017 results and details on our fiscal 2018 full year and first quarter guidance.
