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 Balmuth, Executive Chairman; 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 2016 performance, followed by our outlook for 2017. Afterwards, we'll be happy to respond to any questions you may have.
As noted in today's press release, we are very pleased with our better-than-expected sales and earnings results for both the fourth quarter and fiscal year, especially given our strong multiyear comparison and the highly competitive and promotional holiday season. Our results continue to benefit from our ability to offer customers great values on a wide assortment of gifts and fashions for the family and the home.
Earnings per share for the fourth quarter grew 17% to $0.77 on net earnings that rose 14% to $301 million. Sales for the quarter increased 8% to $3.5 billion, with comparable store sales up 4% on top of last year's 4% gain.
For the 2016 fiscal year, earnings per share grew 13% to $2.83, while net earnings rose 10% to $1.1 billion. Sales grew 8% to $12.9 billion, with comparable sales up 4% on top of a 4% gain in 2015.
dd's DISCOUNTS customers also responded positively to its merchandise assortment, which led to solid growth in sales and operating profit at dd's for both the quarter and fiscal 2016.
For the fourth quarter, Shoes and Men's were the best-performing merchandise categories at Ross, while the Midwest and Southeast were the strongest regions. Our fourth quarter operating margin of 13.6% was up 90 basis points from last year. This improvement was mainly driven by our above-plan sales, along with a favorable comparison of packaway-related costs versus last year's fourth quarter.
For the full year, operating margin increased 40 basis points to a new record of 14%. As we ended 2016, total consolidated inventories were up 7% over the prior year, with packaway levels at 49% of total inventories compared to 47% last year. Average in-store inventories were up slightly at year-end.
As noted in today's press release, our board authorized a new program to repurchase $1.75 billion of our common stock over the next 2 fiscal years. This represents a 25% increase over the prior 2-year $1.4 billion authorization that was completed at the end of the fourth quarter. The board also approved an increase in the quarterly cash dividend to $0.16 per share, up 19% on top of a 15% increase in the prior year.
The continued growth of our shareholder payouts reflects our ongoing confidence in the company's ability to generate significant amounts of cash after funding our growth and the other capital needs of our 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 unwavering commitment to enhancing stockholder value and returns.
Now Michael Hartshorn will provide further color on our 2016 results and details on our fiscal 2017 full year and first quarter guidance.
