Thanks, Tom. Good morning, everyone. As Tom indicated, Q4 and full year financial results reflect the benefit of our balanced portfolio, our focus on execution and our strategic progress. They also reflect the continued progress we are making against our financial strategy to drive strong cash flow, delever our balance sheet and deliver mid-teens earnings growth. Let me begin with our P&L. If you have access to the slides posted online, it will be helpful to follow along. I am on Slide 7.
Top line growth was solid this quarter with net sales of $2.713 billion, 4.3% higher than last year, on both a reported and average daily sales basis as we had the same number of selling days in both quarters. Average daily sales grew to $43.1 million. Q4 was down sequentially 3.8% versus Q3 2013, a bit below our normal seasonality due to Federal channel performance. Gross profit for the quarter increased 5.4% to $448.3 million. Gross margin was 10 basis points higher than last year and 50 basis points higher than Q3. As expected, product margin pressure in transactional products continued in the quarter. This was more than offset by a higher contribution from net service contract revenues, which are booked at 100% gross margin, and higher volume incentive rebates, reflecting our success in attaining partner-aligned growth goals for both for certain transactional products and warranties.
Reported SG&A including advertising expense was $306.3 million, up 3.9%. Advertising expense was up $2.6 million in the quarter as we put more dollars to work to build our brand. This year, we continued to highlight our "People Who Get It" campaign with Gordon & Taylor featuring Charles Barkley. And we had some of the highest NFL viewership since the "People Who Get It" campaign began. Lower non-cash equity compensation and lower historical retention cost offset nearly half of the increase in reported SG&A including advertising. Our adjusted SG&A was $248.1 million, up 7.3% versus last year. As you can see on Slide 8, adjusted SG&A for the quarter excluded non-cash equity compensation of $2.2 million, litigation of $4.1 million, secondary offering expenses of $700,000, depreciation and amortization of $51.3 million and other miscellaneous costs.
As I mentioned on our third quarter conference call, our Q4 adjusted SG&A increased at a rate higher than net sales, reflecting higher sales commissions and other variable compensation costs, consistent with increased sales and gross profits, as well as the planned investment in coworker count and advertising we shared with you last quarter. One of the reasons we provide our adjusted SG&A to you is so you can more easily understand our adjusted EBITDA, which you can essentially calculate by taking our gross profits and subtracting our adjusted SG&A.
We ended the quarter with 6,967 coworkers, up 163 coworkers since the beginning of the year. We continued to drive sales productivity with annualized sales per coworker of $1.56 million, up 4.6% over 2012. As you can see on the next slide, adjusted EBITDA came in for the quarter at $201.2 million, up 3.2%. We delivered an adjusted EBITDA margin of 7.4%, down just 10 basis points from last year.
Looking at the rest of the P&L on Slide 10. Interest expense for the quarter was 31% lower than last year at $51.5 million and included a reduction of $2.1 million related to interest equalization from the redemption of $155 million of our 12.535% senior subordinated notes in the quarter. During the quarter, our tax rate was 27.5% versus 30.8% in the fourth quarter of 2012. Our book tax rate for the quarter was below our year-to-date rate as we booked approximately $7 million of nonrecurring tax benefit, most of which are related to the deferred state income taxes. On a GAAP basis, we earned net income of $60 million in the quarter.
Looking at non-GAAP net income, which better reflects our operating performance, we earned $93.6 million in the quarter, up 43.5% over last year. As you can see on Slide 11, non-GAAP net income reflects after-tax add-backs that fall into 4 general buckets: the ongoing amortization of intangibles from our going-private transaction; any nonrecurring costs related to financings, including debt extinguishment and interest equalization; ongoing non-cash equity compensation; and other onetime nonrecurring income or expenses, which for this quarter included secondary offering expenses and litigation costs. These adjustments are tax effected at a normalized effective tax rate of 39%.
With Q4 non-GAAP fully diluted average shares outstanding of 172.1 million, we delivered $0.54 of non-GAAP net income per share, up 43%.
Quickly turning to full year results. Revenue was $10.8 billion, an increase of 6.3%, both on a reported and average daily sales basis. Gross profit for the year was $1.76 billion, up 5.4%. Gross profit margin was 16.3% versus 16.5% last year. SG&A including advertising was $1.25 billion, up 8%, reflecting onetime IPO and secondary offering-related expenses, non-cash equity and retention compensation and other onetime items. Adjusted SG&A was $955.5 million, up 5.4%, again reflecting higher compensation cost related to increased sales and gross profit and our investment in additional coworkers. Adjusted EBITDA for the year was up 5.5% to $808.5 million, and our adjusted EBITDA margin was 7.5% versus 7.6% last year. Our effective tax rate was 32.1% in 2013 compared to 36.1% in 2012. Net income was $132.8 million for the year compared to $119 million in 2012. Non-GAAP net income was $314.3 million, up 27.2% over last year, and non-GAAP net income per share was up 27% at $1.83 per share.
As I mentioned earlier, during the quarter, we continued to enhance our balance sheet, redeeming an additional $155 million of our senior sub notes. After the October redemption, there was $92.5 million remaining of these notes. We redeemed $30 million of this on January 22 and we'll redeem another $20 million on February 21. We currently expect to redeem the remaining $42.5 million in the next 6 months.
On December 31, we had $188 million of cash and cash equivalents, including money pending for the January 27 and February 21 redemption. We had $3.06 billion of debt, net of this cash on the books, $670 million less than our December 31, 2012, balance. Our cash plus revolver availability was $829 million. Net debt to trailing 12-month EBITDA at the end of 2013 was 3.8x, representing a deleveraging of 1.1 turns compared to 4.9x ratio at the end of 2012. On a pro forma basis for the 2 redemptions in the first quarter of 2014, our weighted average interest rate on our outstanding debt is 6%. In this potentially increasing interest rate environment, I'd like to remind you that our $1.53 billion term loan facility is subject to a 1% LIBOR floor, and we have in place 1.5 -- $1.15 billion principal amount of cap at a weighted average rate of 2.4%. This cap expires in Q1 of 2015.
Pro forma for this quarter's redemption, 88% of outstanding debt is effectively fixed or hedged, and rates would have to move significantly before they had a material impact on our interest costs. Free cash flow for the year, which we calculate as operating cash flow plus the net change in our flooring agreement less capital expenditure, was $327 million compared to $246 million in 2012. For 2013, our free cash flow reflects the benefit of lower cash taxes primarily due to deductions related to the IPO and refinancing-related expenses.
Our ability to drive returns in this business is tied to our working capital management. As I mentioned on last quarter's call, our normal seasonality results in an uptick in our cash conversion cycle in the fourth quarter. That said, in the fourth quarter, we continued to deliver strong working capital metrics. The details by component are provided on Slide 15. Using a rolling 3-month calculation, our cash conversion cycle was at 24 days for the quarter, on par with last year. We expect to continue to maintain our cash conversion cycle within our target range of the low- to mid-20s in 2014.
Turning to 2014, as Tom mentioned, for our top line, we continue to target growth 200 to 300 basis points faster than the U.S. IT market. We also continue to target 3 key medium-term financial measures: adjusted EBITDA margin in the mid-7% range; mid-teens non-GAAP earnings growth per share, which we expect to exceed again this year, likely hitting high teens; and deleveraging 1/3 to 1/2 term per year until we hit our target leverage of 3x. Keep in mind that we view the medium term as the next 2 years, and we hold ourselves accountable for delivering these targets on an annual basis, not quarterly.
Let me provide you with a few additional comments for those modeling our 2014 financials. The move of our financial services and legal verticals from Small Business into MedLar results in a move of approximately $150 million of annual 2013 net sales from Small Business into MedLar. Our book and cash interest expense are both expected to be approximately $200 million in 2014, and we expect our 2014 book tax rate to be higher than 2013, in the 37% to 38% range. For share count, we expect fully diluted shares to be just shy of 173 million.
When modeling our quarterly results, keep in mind that our first quarter sales are typically sequentially below our fourth quarter, so SG&A as a percentage of sales is typically higher. Also, we will be lapping a very strong Q1 2013 gross margin percentage at 16.7%. So although we expect to be on our target range for our full year EBITDA -- adjusted EBITDA margin in the mid-7%, we anticipate that Q1 results will fall below the low end of that range. Another thing to keep in mind as you model our quarters is the phasing of our book taxes this year and their impact in our year-over-year EPS growth. Given the overlap of the 27.5% tax rate we had in Q4 of 2013, you should expect 2014 non-GAAP net income growth to be stronger in the first 3 quarters of the year.
Finally, a few notes for those of you modeling cash flows. Our capital expenditures tend to run 0.5% of net sales. For cash taxes, you should note that this year we begin paying taxes on the cancellation of indebtedness income that we incurred in 2009 and were able to differ to 2014 through 2018. This will result in incremental cash taxes of approximately $21 million to $22 million per year for the next 5 years. For 2014, that will be on top of our marginal cash tax rate of 39%. Remember to apply this rate to pretax book income before acquisition-related intangible amortization, which is approximately $40 million per quarter. And remember, cash tax payments tend to fluctuate throughout the year with lowest in Q1 and highest in Q2 as we pay estimated taxes for both Q1 and Q2 in the second quarter.
One final note. Returning cash to shareholders is an important component of our commitment to build shareholder value, and I am delighted to report that our Board of Directors declared our second quarterly cash dividend since our return to the public market. We will pay a dividend of $0.0425 per share on March 10 to the shareholders of record February 25. We intend to revisit our dividend policy annually, and once we achieve our current target leverage ratio of 3x, we will look at our overall strategy to return cash to shareholders, which depending on tax policy and interest rates at that time, could include share repurchases.
That concludes the financial summary. Let's go ahead and open it up for questions. [Operator Instructions] Operator, please provide the instructions for asking a question.
