Thanks, Jen, and good morning, everyone. I'm pleased with the progress made throughout 2017 and ending the year with adjusted fourth quarter EPS growth of 13% compared to the prior year. As the team noted, fourth quarter sales accelerated, delivering our best quarter of the year. Margins continued to demonstrate quarterly sequential improvement, which has been one of our objectives throughout the year.
As I review the quarter and the year, my comments will focus on the adjusted financials, which exclude certain items as detailed in the press release and tabled on Pages 4 through 9 of the investor presentation.
First, looking at the fourth quarter. Total revenue for the 14 weeks increased 12% to $1.23 billion compared to $1.1 billion for the 13-week period last year. Total revenue grew by $131 million, which included $43 million from the extra week.
Comparable sales for the 14 weeks increased 8%, following a slight increase in comps over the same 14-week period last year. The 8% increase was our strongest comp sales performance since the third quarter of fiscal 2015. Additional sales information can be found on Page 11 of the investor presentation.
By brand, fourth quarter American Eagle comps were up 5% and Aerie comps increased 34%. Both stores and the digital business grew in the quarter with stores increasing in the low-single digits and digital sales growing over 20%.
Digital penetration increased 340 basis points, expanding to just under 31% of revenue in the fourth quarter compared to 27% a year ago. Regarding our quality of sale metrics on a consolidated basis, traffic and transactions increased with store traffic posting a positive comp, outperforming the mall for both brands. Favorable product mix contributed to a low single-digit increase in the average unit retail price, while the average dollar sale was up slightly.
Gross profit dollars increased $37 million to $425 million, up 9% from $389 million last year. The gross margin declined 80 basis points to 34.6% of revenue compared to 35.4% last year, the lowest decline of the year. The decrease in margin reflected higher promotional activity. Additionally, increased shipping cost and higher compensation were offset by rent leverage.
SG&A expense of 264 million leveraged 60 basis points to 21.5% as a rate of revenue, driven by strong sales growth. Increased store salaries in support of the strong holiday season, incentive compensation and expenses related to the extra week in the fourth quarter drove the dollar increase from $242 million last year.
Depreciation and amortization remained flat at 3.6% as a rate of revenue with dollars increasing to $44 million compared to $39 million last year. Adjusted operating income of $118 million rose 10% compared to $107 million last year while deleveraging 20 basis points to 9.6% as a rate to revenue. Adjusted fourth quarter EPS of $0.44 increased 13% compared to adjusted EPS of $0.39 last year.
Now a few comments and highlights regarding our annual results. After a challenging first half of the year, business recovered in the second half, driven by better overall traffic trends and improved product assortments, particularly in men's tops. Sales strengthened as the year progressed and we saw improvement in both gross margin and operating margin. Total revenue for the 53 weeks increased $186 million or 5% to a record $3.8 billion compared to $3.6 billion for the 52 weeks last year.
Consolidated comparable sales for 53 weeks increased 4% following a 3% increase last year. AE brand comp rose 2% and Aerie comps were up 27%. AE comps showed improvement each quarter this year, and Aerie continues to grow at a fast pace with this quarter marking 15 straight quarters of comp growth with the last 13 rising in the double digits.
Adjusted gross profit dollars increased slightly with a sharp decline in the first half, offset by growth in the second half. For the year, we deleveraged 170 basis points to 36.2% as a rate to revenue due to higher promotional activity primarily. The digitally increased delivery to support strong digital business was offset partially by rent leverage. We successfully cut gross margin erosion for 270 basis points in the first quarter to only 80 basis points of decline in the fourth quarter.
Demonstrating good expense management, the SG&A leveraged each quarter this year. The annual rate of 23.2%, reflects a 60 basis point improvement. For the year, adjusted operating income of $325 million decreased 8% from $353 million last year, deleveraging 120 basis points to 8.6% as a rate to revenue.
In this fiscal year, we incurred total restructuring and related charges of $30 million or $0.11 per share, consisting primarily of charges corresponding to the closure or conversion of international owned and operated stores to license partnerships, home office restructuring activities and charges related to the planned exit of a joint business venture. Adjusted EPS of $1.16 decreased 7% compared to adjusted EPS of $1.25 last year. For additional information, please refer to Page 7 of the investor presentation.
As noted in our GAAP statements, our reported fourth quarter in fiscal year EPS of $0.52 and $1.13, respectively, included an $0.08 benefit from the impact of U.S. tax legislation, which is excluded from the adjusted earnings. The benefit relates to a lower blended U.S. corporate tax rate, a net benefit from the remeasurement of the deferred tax balances and a onetime transition tax on unrepatriated earnings of foreign subsidiaries and a benefit related to the acceleration of certain deductions into fiscal 2017.
Now turning to the balance sheet, starting with inventory. Total ending inventories at cost increased 11% to $398 million. Higher inventory reflects strategic investments in men's and women's bottoms, women's tops and Aerie apparel to support strong sales trends and new stores. Additionally, as noted last quarter, a change of the use of clearance stores to liquidate inventory has increased on-hand inventory levels, which will continue until we anniversary this change in strategy in the third quarter of 2018.
Looking forward, we expect first quarter inventory to be up in a low double digits with 2% to 3 percentage points driven by our new clearance strategy. We ended the year with $414 million in cash and investments. As a result of strong free cash flow, cash increased $35 million compared to last year.
During 2017, we returned a total of $176 million to shareholders, paid dividends of $89 million and we repurchased 6 million shares for $88 million. Today, we also announced a 10% increase on our quarterly cash dividend, in part reflecting strong cash flow, which will increase as a result of the new U.S. tax legislation.
Consistent with our guidance, capital expenditures totaled $169 million for the year. For 2018, we expect CapEx to be in the range of $180 million to $190 million. The increase is due to an acceleration of Aerie growth, store remodeling projects and the balance to support the digital business, omnichannel tools and general corporate maintenance.
2017 store activity can be found on Pages 15 through 17 of the investor presentation. Total gross square footage declined slightly in the year as we continue to close underperforming stores, including 25 AE stores and 8 old format Aerie stores. We opened 15 AE stores, 15 Aerie standalone stores and 28 Aerie side-by-side stores in 2017. Rightsizing our store fleet with the success of our digital business continues to be a high priority for our teams as we continue to use customer data analytics to help in our decision-making.
Our plans to strategically expand in the new market has not changed. In 2018, we'll add 35 to 40 new Aerie stores, of which 10 to 15 will be standalone stores, with the balance to represent side-by-side Aerie locations. Additionally, we will open 15 to 20 AE stores, and we are currently planning to close 5 to 10 old format Aerie stores and 10 to 15 AE stores in 2018.
Now regarding our outlook. We're off to a very positive start this season. In the first quarter, we expect earnings per share of $0.20 to $0.22 based on comp sales in the positive mid-single digits. The first quarter EPS guidance compares to adjusted EPS of $0.16 last year and excludes potential asset impairment or restructuring charges.
Our anticipated effective tax rate for the quarter and the year is in the mid-20s, yielding roughly $60 million of incremental cash flow and approximately $0.20 of EPS after making additional investments in our brands.
In closing, we remain focused on driving improvements across the business to produce better earnings flow-through while fueling growth in our brands. The future is bright as we look at opportunities ahead. Our goal is to deliver consistent online results while creating sustained shareholder value.
And now we'll open it up to questions.
