Please note that on this call, we will be referencing certain non-GAAP measures, such as adjusted EBITDA, adjusted net income and free cash flow. These non-GAAP measures are intended to supplement the comparable GAAP measures. Reconciliations between the GAAP and non-GAAP measures are included in today's press release. I will now turn the call over to Peter Dameris.

Peter?

Peter Dameris -- Chief Executive Officer

Thank you, Jason. During our call today, I will comment on the markets we serve and our financial highlights. Ted, Rand and George will then discuss the performance of our operating segments in greater detail before turning the call over to Ed for a detailed review of our fourth-quarter results and our estimates for the first quarter of 2019. Now on to the fourth-quarter results.

Revenues for the quarter were $929.7 million, up 36.9% year over year on a reported basis or 11.8% on a pro forma basis. Our growth rate for the fourth quarter was not only higher than the third quarter, it was the fastest quarterly year-over-year growth rate for any quarter in 2018. Our strong performance is indicative of the overall strength of the U.S. economy and labor markets and the health of the federal market.

Our IT business continues to see high demand from its customers, driven in part by greater adoption of staff augmentation as a viable alternative to outsourcing, offshoring and consulting. We believe that we are well positioned to continue to service our customers' IT needs as technology rapidly evolves and is adopted. Our size and service offerings allowed us to grow faster than the published IT services industry growth rates, and we believe that we are well positioned to generate solid above-market revenue growth in the future. During the quarter, we saw strong double-digit revenue growth at Apex Systems, strong performance from Creative Circle and continued year-over-year growth at Oxford Core and our Oxford segment.

Our Federal IT services and solutions business, ECS, grew revenues at roughly twice the projected annual growth rate of its peer group for 2018. ECS has grown above its peer group's organic growth rate in each of the last three quarters, following the acquisition by ASGN. Customer demand was strong across our federal, local, mid-market and large national accounts. Adjusted EBITDA was up 31.5% year over year to $109 million and cash generation continues to be at or above our expectations.

Our adjusted EBITDA margin was slightly below the midpoint of our guidance due to $7.1 million in software sales under one of ECS' government contracts, which carries a lower gross margin, and higher-than-expected flow of revenues from certain of Apex's larger customers, which also carry a lower gross margin. Free cash flow was $57.3 million and our leverage ratio was 2.69 times trailing 12 months adjusted EBITDA at the end of the quarter. For the full year, we paid down $286 million in debt, including $276 million since the closing of the ECS acquisition. Despite normal quarterly seasonality and the payment of the cash for the DHA acquisition and the annual cash bonuses in the first quarter, the company anticipates that its leverage ratio at the end of the first quarter will be 2.65 times, down from 2.69 times at the end of the fourth quarter.

As we look ahead to the remainder of 2019, we anticipate our leverage ratio will be below two times by the end of the year, assuming no further acquisitions. With respect to recent production at our Apex and Oxford segments, our weekly assignment revenues, which exclude conversion, billable expenses and direct placement revenues, averaged $48.8 million for the last two weeks of the quarter, up 11.2% over the same period in 2017. Our Federal IT services and solutions business continues to see new long-term contract awards, robust spending against existing contracts and the forward positive benefits of increased funding and visibility of defense, intelligence and federal civil agency budgets, particularly in the areas of artificial intelligence and machine learning. During the quarter, ECS secured $196.6 million in new awards.

George will speak in more detail regarding these recent awards. On January 28, we announced the acquisition of DHA for our ECS segment. DHA is a provider of mobility, cybersecurity, cloud and IT services to the Federal Bureau of Investigation and other federal customers. DHA's services are delivered primarily through prime, full and open contracts.

Its performance reputation in delivering technical support will strengthen ECS' rapidly growing presence across cybersecurity and other operational domains in the national security intelligence community. I would like to now turn the call over to Ted Hanson, who will review the operations of the segments. Ted?

Ted Hanson -- President

Thank you, Peter. For the fourth quarter, all three segments contributed to ASGN's growth. The Apex segment, which Rand will review in a few moments, grew 13.1% year over year, and the Oxford Segment grew 4.8% from the fourth quarter of last year. The Apex and Oxford markets we serve in IT, digital/creative marketing, life sciences and engineering all remained stable and productive during and exiting the quarter.

Secular changes remain in our favor with regards to how our customers are evolving their approach to supporting business needs and getting projects completed. While our staffing services continue to grow, and we take share with greater than market growth rate, our value-added service offerings or consultative work are growing at a much faster pace. The Oxford Segment is comprised of Oxford Core, CyberCoders, our permanent placement business, and Life Sciences Europe. For the fourth quarter of 2018, Oxford Segment revenues were $151.2 million, up 4.8% year over year or 5.5% on a constant currency basis.

For the full 2018 year, the Oxford Segment generated $606.5 million in revenues and was up 3% year over year, with all units positively contributing to growth. Oxford Core revenues, which account for approximately 75.5% of the segment revenues, were up approximately 5.6% year over year or 6.1% on a constant currency basis and in line with our expectations. CyberCoders, our permanent placement service offering, which accounts for 97.4% of the segment's permanent placement revenues, had 4.1% growth year over year, meeting our initial expectations. Gross margin for the segment was 40.7%, coming in slightly ahead of initial expectations for the quarter, but down 110 basis points year over year due in large part to business mix within the segment.

As we typically do, let me give some color to the progress in Oxford Core. In 2018, Oxford Core returned to a position of year-over-year growth, ending the year with the highest quarterly year-over-year growth rate. Q4 showed varying degrees of performance in each of our four disciplines in the U.S. and Europe, with strong growth in our domestic IT and engineering offerings, along with strong growth in our European business.

It is a longer road to truly institutionalize our sales strategy and build upon the productivity we have created over the last few quarters. However, we are pleased with the progress we have shown during the course of 2018, and our results provide us confidence that our actions will lead to continued growth, increased productivity and consistently improving bottom-line results. In 2019, the results of our Life Sciences Europe division, the smallest division within the Oxford Segment and ASGN, will be incorporated within the overall Oxford Core results, and we will continue to provide commentary on the performance of that business unit, both in the United States and in Europe. I will now turn the call over to Rand Blazer.

Rand?

Rand Blazer -- President of Apex Systems

All right. Well, thank you, Ted. The Apex Segment, which consists of Apex Systems, Apex Life Sciences and Creative Circle business units, again reported solid results for the quarter and finished a very strong year. Revenues for this segment in the fourth quarter were $604.6 million, up 13.1% year over year.

Revenue for the year was $2.3 billion, up 12.9% for the full year versus 2017. Apex Systems, which consists of 76.2% of the segment's revenues in the quarter, continued to lead the way with 14% year-over-year revenue growth in the fourth quarter, and ended the year with 13.8% growth over 2017. Our Creative Circle unit posted solid year-over-year revenue growth for the fourth quarter at 9.8%. And our Life Sciences unit was up 10.9%.

Gross margin for the segment was slightly up year over year, reflecting stable pricing in our end markets. Our segment's EBITDA also grew double digits in the fourth quarter, and once again, outpaced top-line growth, both in the quarter and on a full year basis. Our EBITDA performance and conversion of gross profit to EBITDA was driven by revenue growth and continued strong productivity of our sales, delivery and infrastructure teams. To give a little more color, Apex Systems' revenue growth and performance was broadly driven by the following factors: Apex achieved double-digit revenue growth in four of the seven industry verticals we service, including financial services, healthcare, consumer industrial and technology industry accounts.

Of the remaining three industry verticals, aerospace and defense and telecommunications accounts grew mid-single digits, while business service accounts exhibited low single-digit growth year over year. Growth was achieved in both our top accounts and retail or brand-centric accounts, with top accounts and retail accounts growing double digits. Growth in our consultative-type work remained strong in the quarter and continues to outpace our expectations and our overall revenue growth rate. Finally, as mentioned, our field and back-office operations exhibited exceptional productivity during the quarter, while supporting Apex Systems' EBITDA performance.

Creative Circle's revenue grew just shy of double digits in the quarter on an as-reported basis, with growth being driven by Creative Circle's top accounts program and digital marketing skill sets. With this latest quarter's performance, the Creative Circle unit continues to exceed our expectations for overall profitability. Our Life Sciences business revenue growth was also up, again driven by strength in our Life Sciences top accounts and in our clinical skill set. Over the past year, we have worked hard to move Apex Systems and Apex Life Sciences units closer together.

These units share the same back office, many same top accounts, and today, have common field leadership. These past actions have allowed us to achieve certain synergies in our business and strengthen client service as we have built critical mass in our sales and delivery teams and provided our client accounts a full capability across both IT and Life Sciences skill sets. Because of the success of these past actions, beginning in Q1 of 2019, the performance of our Apex Systems and Apex Life Sciences units will be reported as one singular unit, Apex Systems. We will still provide visibility of our Life Sciences performance as the 8th industry within Apex Systems.

In conclusion, the Apex Segment continues to outpace the performance of the overall IT staffing and services industry, and yet another solid quarter, wrapping up a successful 2018. George, I'll turn the call over to you.

George Wilson -- President of ECS

Thank you, Rand. ECS had really strong performance in the fourth quarter of 2018, both from a financial and operational standpoint. ECS reported revenues of $173.9 million, an increase of 14% year over year and 6% sequentially against the third quarter of 2018. This growth continues to be ahead of the industry average for peer companies operating in the federal technology space.

We have seen continued strong demand for services and solutions in areas of cybersecurity, cloud, artificial intelligence and digital transformation, key business areas for ECS. Also, we see continued increasing customer interest in IT modernization. These are areas where ECS is well positioned to support our clients with deep customer knowledge, required IT skills, relevant technology partnerships and the needed contract vehicles. In the fourth quarter, we received a total of $196.6 million in contract awards for a 1.1 book-to-bill during a seasonally slow quarter.

New awards included cybersecurity work supporting the U.S. Federal Bureau of Investigations, cloud managed services for a commercial client, cloud and software development solutions for the U.S. Marine Corps and digital modernization efforts for the Defense Health Agency. Subsequent to year-end, we secured a yet to be announced large cyber award and are looking forward to an even larger book-to-bill ratio in the first quarter of 2019.

We see continued strong proposal activity and have a significant backlog of proposals submitted and awaiting award. At year-end, ECS had $1.4 billion in total contract backlog, which equates to a healthy coverage ratio of 2.3 times our trailing 12-month revenues. During the fourth quarter, ECS continued to strengthen its technical skills and business partnerships with commercial providers in cloud, cyber, risk management and artificial intelligence. From a profitability standpoint, ECS' adjusted EBITDA grew 3.5% compared to the last quarter of 2017.

I will now turn the call over to Ed Pierce to discuss ASGN's overall financial results. Ed?

Ed Pierce -- Chief Financial Officer

Yes. Thanks, George. As Peter mentioned, revenues for the quarter were up 11.8% year over year on a pro forma basis and exceeded our previously announced estimates by $14.7 million or 1.6%. The favorable variance was mainly related to higher revenues from large accounts at Apex and higher revenues at ECS, which included $7.1 million in software sales that had been expected to occur in the first quarter of 2019.

The combined effects of changes in foreign exchange rates and differences in billable days did not have a significant impact on our year-over-year growth rate. Gross margin for the quarter of 29.2% was slightly lower than our previously announced estimates. The variance was mainly the result of a higher mix of revenues from Apex and ECS, which have a lower margin than our Oxford Segment and a higher mix of revenues from large volume, low-margin accounts at Apex. SG&A expenses for the quarter were higher than our previously announced estimates, mainly because of the acquisition and integration expenses of $1.8 million, which we do not include in our guidance estimates.

Amortization of intangibles was $13.8 million, up year over year as a result of the acquisition of ECS and $4.8 million lower than our guidance estimates. Now the favorable variance related to a change in the estimated useful life of ECS' backlog intangible assets, which now more closely matches the estimated cash flows of the underlying funded contract awards. As mentioned in today's release, we have finalized the purchase accounting for ECS, and there were no significant changes in asset values from their initial determination. As part of this finalization, we revised the contract backlog estimate as of the acquisition date and recalculated the book-to-bill ratios for the second and third quarters of 2018, and these revisions are included in today's press release.

Interest expense for the quarter was $14.2 million, compared with $6 million in the fourth quarter of 2017. Interest expense for the quarter was comprised of $12.7 million of interest on the credit facility and $1.5 million of amortization of deferred loan costs. Sequentially, interest expense was down approximately $0.4 million due to lower average outstanding borrowings, partially offset by a 22 basis point increase in the average interest rate. Our effective tax rate for the quarter was 23.7%, compared with our guidance estimates of 26%.

The lower rate reflected, among other things, excess tax benefits of stock-based compensation, which we do not include in our guidance estimates, and lower estimated book-to-tax differences for the full year. Our provision for income taxes for the fourth quarter of 2017 included a one-time noncash benefit of $31.4 million related to the remeasurement of our net deferred income tax liabilities as a result of income tax reform. This one-time adjustment was the reason net income for the fourth quarter of 2017 exceeded that of the current quarter. Net income and adjusted net income were both above our guidance estimates, but below the fourth quarter of last year because of the one-time tax benefit of $31.4 million.

Adjusted EBITDA for the quarter was $109 million, up 31.5% year over year on a reported basis. Cash flows from operating activities were $63.9 million and free cash flow was $57.3 million or 6.2% of revenues. During the quarter, we repaid $55 million of our long-term debt. Accounts receivable day sales outstanding were 60.1, or 2.6 days more than the end of the preceding quarter.

Each day is approximately $10 million. The increase in DSOs was mainly related to the government shutdown and have since returned to more normal levels. For the first quarter of 2019, revenues are estimated to range from $916.6 million to $926.6 million, which includes approximately $11 million in revenues from DHA. Excluding DHA, our estimates imply year-over-year pro forma growth of 8.5% to 9.7% on one fewer billable day.

On the same billable day and constant currency basis, our estimated revenue growth rate ranges from 10.6% to 11.8%. Our sequential growth rate reflects normal seasonal spending patterns of our commercial and government customers, such as lower spending in the first quarter on software and hardware sales to our government customers, ramp-up of spending following the completion and release of our customers' IT budgets at the beginning of each fiscal year, and the effects of $7.1 million in software sales that occurred in the fourth quarter of 2018 which had been expected to occur in the first quarter of 2019. As Peter mentioned earlier, demand and momentum going into 2019 is strong as demonstrated by the year-over-year growth rate over the last two weeks of 11.2%. Net income is estimated to range from $35.8 million to $39.5 million, adjusted net income from $48.8 million to $52.5 million and adjusted EBITDA from $96.3 million to $101.3 million.

Our adjusted net income estimates do not include the quarterly cash tax savings of $7 million related to the amortization deduction for goodwill and trademarks. I will now turn the call back over to Peter for some closing remarks. Peter?

Peter Dameris -- Chief Executive Officer

Thank you, Ed. As our quarterly results continue to prove out, our scale, size and breadth of services has us well positioned to benefit during a period of historic secular growth for the services industry. Without a doubt, the world of work is changing. Accelerating digital transformations coupled with favorable labor and immigration legislation and an improving and stable U.S.

governmental market are all market forces occurring in our space. We are optimistic that ASGN is well situated to continue experiencing strong results into the foreseeable future. The entire ASGN team is pleased with our fourth-quarter performance and our results for 2018 as a whole. We entered 2019 with a healthy tailwind in all of our segments and are optimistic that we will drive continued performance in the first quarter.

As we stated before, our focus remains on growing the business profitably, along with maintaining our healthy rate of growth. To conclude our prepared remarks, I want to take a moment to acknowledge and congratulate our many loyal, dedicated and talented employees, whose efforts have enabled ASGN to progress to where we are today. Thank you for your time. I would like to now open the call up to participants for questions.

Questions and Answers:

Operator

Thank you. [Operator instructions] Our first question will come from the line of Jeff Silber with BMO Capital Markets. Please go ahead.

Jeff Silber -- BMO Capital Markets -- Analyst

Thanks so much. Close enough. In looking at your supplemental materials, you provided a lot of information. I specifically was focusing on the change in your staffing consultants.

I think it went up about 10% in Apex, but went down slightly in Oxford. Is there anything to read into that? And I'm just curious what your plans are for the two different divisions regarding internal headcount for 2019. Thanks.

Peter Dameris -- Chief Executive Officer

Yes, thanks. I think on a normal basis, we always say that we're going to invest in headcount, and it's likely just a little bit less than the rate of growth in the business. If you see in any one quarter that maybe we have a headcount fall like in Oxford, it may be seasonal around a little bit of turnover in the fourth quarter. It take us a little while to attract talent at the end of the year, but our goal there is to continue to invest.

I don't think our plans have changed at all there.

Jeff Silber -- BMO Capital Markets -- Analyst

OK. Fair enough. In the prepared remarks, you alluded to the government shutdown and just talking about the increase in DSOs. Was there any other impact on your business in the quarter? Should we expect any kind of collateral damage, so to speak, for the rest of the year?

Peter Dameris -- Chief Executive Officer

Yes. So as it relates to the government shutdown, really very little impact on revenues in the fourth quarter, and I think we estimated a couple of million for the first quarter. Now with that said, there has been a slowdown in approval of newly completed work or resolution of protest. But that's just a deferral.

It's not a loss of opportunity or business.

Jeff Silber -- BMO Capital Markets -- Analyst

OK. My final question, I'm sorry. Just dealing with your M&A strategy. I guess, the last couple of larger acquisitions has been focusing on the government contract area.

Is that where your focus is going to be going forward in terms of M&A?

Peter Dameris -- Chief Executive Officer

No. Jeff, it's wherever we see the best opportunity strategically and as far as ease of integration. As you saw from Apex, we just have a juggernaut there that grew 2.5 times to three times of the industry, and it's better to deploy SG&A versus buying something. To the extent that we found something interesting that enhances the services that we can offer our clients at Apex, we do it.

And the government space, we've told you previously that our goal is to get to $1 billion in revenue for that segment. And we think that provides them with different credentials and credibility, and the ease of integration, it's a little bit different on the government space than it is in the commercial space. And there are some real opportunities to add to our delivery capabilities. So the last couple of deals, one was a platform, ECS, and then the second was DHA, to add to capabilities.

But we're looking across the universe of the services that our customers need, and can we build it organically quick enough or do we need to buy a company to deliver it to our customers.

Jeff Silber -- BMO Capital Markets -- Analyst

OK. I appreciate the color. Thanks so much.

Operator

Thank you. And next, we'll go to the line of Gary Bisbee with Bank of America. Please go ahead.

Gary Bisbee -- Bank of America Merrill Lynch -- Analyst

Hey, guys. Good afternoon. I guess, first question, on the software sale within ECS, can you just help us understand, should we think of that as more onetime? Or is this something that happens on a recurring basis with some of these, it's just a little more episodic in nature? And are you willing to say, just the last part of that, how much that actually impacted the gross margin? So in other words, ex that was the gross margin about how it had been trending for the segment earlier in the year? Thank you.

Peter Dameris -- Chief Executive Officer

Yes. So I'll go first, and then I'll ask George to add some color. But one, these software licenses and hardware are instrumental and necessary for us to deliver the solution to our governmental customer. So no way should you construe that we're in the business of selling independently software and hardware.

This is -- we can't deliver the solution, our artificial intelligence, machine learning without the software and the equipment they may reside on. There is some seasonality, Gary, to how that hardware, software spend occurs against these contracts, typically more in the fourth than you would see in the third or second. We can't -- we're not breaking out what the impact is to the gross margin. I would just tell you that gross margins on a line item basis within ECS are relatively stable.

It just has to do to the impact as you're alluding to of how much software, hardware sale flow through a quarter versus another quarter. George, would you like to add something to that?

George Wilson -- President of ECS

Yes. Thanks, Peter. The only thing I'd emphasize is the seasonality of it in hitting in Q4 as opposed to what we normally thought was going to hit in Q1. And the gross margins, just minor impact, but I don't think we provide the details on those kind of things.

But as Peter said, it's part of our solutions set, it is continuing a part of our business. Moving forward, we'll expect some more of this, but Q4 has been a lot heavier than Q1 in every year in terms of getting the licenses and such to deliver our solutions.

Gary Bisbee -- Bank of America Merrill Lynch -- Analyst

Great. Thanks. And then just to follow-up. For the business overall, just -- how, if at all, are you seeing tighter labor markets impact your ability to source talent, number one? And number two, your ability to charge for it in terms of higher bill rates? Any change in the last few months in how you think about either of those factors? Thanks a lot.

Peter Dameris -- Chief Executive Officer

Well, I'm going to give the qualitative response, and then I'll let Rand speak to it a little bit. But I mean, we had the fastest quarterly growth rate of '18 in the fourth despite the unemployment rate continuing to be at historic low levels. So our teams, between their effort, the tools, their brand and the opportunities that we can show a consultant versus someone else have a very attractive recruiting profile. And George and Ted, what would you add to that -- excuse me, Rand and Ted, what would you add to that? Rand?

Rand Blazer -- President of Apex Systems

Well, I'll start. I'll start. And in the supplemental material or the press release Ed gave out, he does give average bill rates. And for Apex, you'll see as you went through Q3 and Q4 2018, our bill rates have increased.

So is the labor market tight? Yes. It's been tight though in the IT world for a long time. You have to really work to make sure you're building your portfolio of resources to deliver to clients. Are we seeing some increase in bill rates? Yes, particularly in certain skill sets.

Gary Bisbee -- Bank of America Merrill Lynch -- Analyst

Great. And then just one last one, on the continued outstanding growth at Apex. You've talked about a lot of factors that have driven that, but is there anything you can call out today as particular important over the last few quarters? Or is it just continue to be the various factors you discussed last year at the investor day?

Peter Dameris -- Chief Executive Officer

Well, I do believe it's the relationships we've created, our size, our credibility. If you're asking was there like a one-time spend, a large project award that wouldn't occur again, this is pretty steady-state business, if that's what you're getting at. Rand, anything else?

Rand Blazer -- President of Apex Systems

No. I agree, Peter. It's just steady state. And Gary, we said all along, when you're investing at the Apex side of the business, you're investing in a portfolio of accounts which continues to grow and deepen.

So that growth and deepening of those account relationships make us a stronger business.

Gary Bisbee -- Bank of America Merrill Lynch -- Analyst

OK. Thanks, guys.

Operator

Thank you. Next, we'll go to the line of Ed Caso with Wells Fargo. Please go ahead.

Rick Eskelsen -- Wells Fargo Securities -- Analyst

Hi. Good afternoon. It's Rick Eskelsen on for Ed. I wonder if we could just drive a little deeper into the ECS business.

Even when you pull out the impact of the past there, the growth has been very strong there. So wondering if you can just provide a little more detail on why you think you are able to outgrow the market by a pretty considerable amount so far?

Peter Dameris -- Chief Executive Officer

Well, George, you go first and then I'll follow.

George Wilson -- President of ECS

Yes. Thanks for the question. We believe we've got the right customers sets, the right capabilities in this market. It's something we've been building here at ECS for the last 10 years, and we feel good about our positioning.

Like I said in my statements, we seem to see the interest, a very heavy interest in cyber, cloud and digital modernization. And we've got the capabilities, the customer relationships as well as the contract vehicles to go accomplish the missions for the customers. We're not a super large company. We'll probably have some more customer intimate relationships than sometimes some of the much larger ones.

So that might give us a little bit of an advantage. But like I just said a second ago, it's our customer relationships, our ability to have the capabilities to solve their problems and have the contract vehicles to respond to them.

Peter Dameris -- Chief Executive Officer

Yes. So Rick, I think our revenue stream is a little more homogeneous than just the broader industry. As you know, we're not trying to be a multi-multibillion dollar government services contractor. We're trying to be a large IT solutions services provider to the government.

So a lot of our skills and practices may be growing faster than some of the other things, like mission support or language translation or passport renewal, outsource contracts that others in that umbrella category of government services might do. And just to reiterate what George said, when you really go on our website, you see the contract vehicles that we are -- we are on as a prime. We really do have the right licenses to compete for large pieces of business, and there has been a good flow. We've been successful over the last couple of years and winning some nice pieces of business.

Rick Eskelsen -- Wells Fargo Securities -- Analyst

Thanks. That make sense. I guess if I could just follow up on the leverage profile as well. I think what you guys have said at the time of the acquisition was you expected to exit this year around 2.5 times, and now you are at about two times.

Just can you talk a little bit about sort of the faster than expecting delevering and the opportunities for other things -- more acquisitions like DNA, any share repurchase, stuff like that. Thank you.

Peter Dameris -- Chief Executive Officer

Well, it's a combination of better conversion of EBITDA to free cash flow and a little faster growth of EBITDA. And as we always say, our shareholders, our shareholders' capital competes for what's the most attractive long-term return, whether it's share repurchase, rapid deleveraging or acquisitions. And in the first quarter, it was to do a little acquisition, and we evaluate it every quarter, what's best.

Rick Eskelsen -- Wells Fargo Securities -- Analyst

Great. Thank you very much.

Operator

Thank you. Next, we'll go to the line of Tim McHugh with William Blair. Please go ahead.

Tim McHugh -- William Blair and Company -- Analyst

Thank you. First, I guess, two questions on ECS. First off, it's the comment about, I guess, EBITDA grew 3.5%, I realize probably a lower margin on that product sale. But is there an increase, I guess, why would generally the EBITDA would be growing a little slower than I thought the underlying revenue? In fact, if I look at the customer breakout there, it feels like DoD and Intelligence, in particular, is driving a substantial part of the growth, and maybe federal and civilian a little slower.

Does that just reflect budget, government budget trends? Or is there something you're seeing more so at one trend in terms of market share gains and customer wins that's driving it?

Peter Dameris -- Chief Executive Officer

Well, our focus really is to be a valued trusted partner to the intelligence and Department of Defense and stay away from some of the civil and civilian agencies. And as you note from our prepared remarks, because our work is deemed essential, the only real big impact we had in our portfolio of business in the first quarter from the shutdown was at the EPA. And so the other stuff was deemed essential and carried on. George, do you want to give a little more color to the components that affected the reported number of the adjusted EBITDA growth?

George Wilson -- President of ECS

Yes, sure. And I'll have to say the same thing that Peter said. We really do focus on mission-critical customers, which happen to be in defense, in the intelligence and law enforcement. And there are some federal civilian organizations that are also very focused on mission-critical, Department of Homeland Security is another example.

And that, again, seems to be married up very well with not just our capabilities, but also our business model in terms of going to the much higher end and trying to solve the most difficult problems. And in those areas are where we're really growing quite a bit, particularly in the AI, ML and software integration areas.

Tim McHugh -- William Blair and Company -- Analyst

OK. Great. Thank you. And then, I guess, just following up on Oxford, I guess.

You're seeing, I guess, I know there's some timing around sales force, but there's also a comment in the prepared remarks about continuously margin improvement. I guess, just more broadly, if we step back, where are you at with kind of productivity levels on Oxford and end margins on Oxford relative to what you consider the ultimate goal or the kind of -- the ideal kind of levels for that business?

Peter Dameris -- Chief Executive Officer

Well, I guess, Tim, we're kind of monitoring that as we go. I think you can see in our gross margin at Oxford that as we create bigger, more meaningful customer relationships that we're having to get that sometimes at a different price. Also, some of it is around business mix, which units are growing the most and what is the margin profile of that unit. But I think, ultimately, not only do we want to sustain best-in-class growth rates above the market, but we also want to find higher levels of productivity from our field staff and from our back-office costs.

And so I think we're midstream on that. That's not changing overnight, but certainly growth is going to begin to help that more, where in the past, we haven't really -- when we weren't growing, we weren't really getting the help there. So I think those are all -- we evaluate those as we go, but certainly we'd love to get better productivity statistics out of our team as we go forward.

Tim McHugh -- William Blair and Company -- Analyst

Fair enough. Thank you.

Operator

Thank you. Next, we go to the line of Mark Marcon with R.W. Baird. Please go ahead.

Mark Marcon -- R.W. Baird -- Analyst

Good afternoon. I was just wondering if we could talk a little bit more about Apex with regards to increasing the mix of statement of work and consulting light engagements and how we should think about that with regards to the margin profile. And also, if you could just give us a little more color in terms of the growth that you're seeing there and who you are replacing?

Peter Dameris -- Chief Executive Officer

Ed?

Ed Pierce -- Chief Financial Officer

Well, the growth rate in our consulting business is growing, I'd say, twice what it is in our staffing business, Mark, so that gives you some sense. The margins are healthier. We don't give out that detail, but they're definitely healthier than staffing, because you're taking more risk and providing more value to the client in the work. The key is to control the risk so it doesn't erode your margin, and yet still deliver more value than you would by just providing staffing support.

Mark Marcon -- R.W. Baird -- Analyst

Should that translate into higher gross margins on a year-over-year basis for -- I mean, as that is growing at twice the rate within the Apex unit? Obviously, there's multiple components within that unit. And so we don't see all of it. But just wondering how we should think about that.

Peter Dameris -- Chief Executive Officer

Well, Mark, we always promise you our goal is to have stable gross margins and expanding EBITDA margins. We didn't have that in the quarter for the reasons we told you. But as you point out, there are various components, whether it's permanent placement and conversion fee contribution, whether it's SOW, whether it's just pure assignment, a contract assignment gross margin. They vary.

And there's more pressure on staffing contract gross margin than there is on others. So it ebbs and flows, but we've been able manage that portfolio of business so that we have a relatively stable to, at times, expanding gross margin. And I think you should consider that. For modeling purposes, we're not predicting a dramatic erosion because we have some tools we can use to adjust if we find ourselves in a difficult pricing environment on the staff aug business.

Mark Marcon -- R.W. Baird -- Analyst

Great. And then with regards to further integrating the Life Sciences within Apex, are there any implications that we should we think about, either from a profitability perspective, growth rate perspective, SG&A leverage perspective? How should we think about that?

Peter Dameris -- Chief Executive Officer

Yes. So a couple of thoughts. One, I don't think there are -- on accounting basis, you're going to see us coming out with the one-time write-offs or things like that for closure of this or that. So I don't think, for modeling purposes, you'll get a bunch of onetime announced, we're stopping this or that, that causes us to recognize a loss.

As it relates to the reported numbers now that they are going to be embedded in Apex, it's going to -- the Life Sciences business was growing fast -- slower, excuse me, slower than Apex. So if you -- but it's so much smaller than Apex. It's not going to have a big number, but it could mute things a little bit, and you shouldn't automatically correlate that to it's a -- in our IT business, it could just be a blend of business. And the margin on the Life Sciences business was slightly lower than Apex's business.

So that could, on a reported basis, cause things to look a little different. So it's incumbent upon us, which we'll try to do, to tell you if there's anything that's reported -- that's affecting the reported numbers. But just want to reiterate, whether in reality things play out this way or not, we're not guiding to compressing gross margins. A quarter here or there may get reported where it looks down 10 or 20 bps, but that's more because of mix of business than we're seeing an erosion.

So Apex, stable gross margins. Apex reported with Life Sciences could feel compressed a little bit, but that's just mixture. That has nothing to do with pricing power at Apex. Did that answer your question?

Mark Marcon -- R.W. Baird -- Analyst

I think so. Although, I mean, I'm not sure how -- I mean, we're blending both together anyway. So why would that impact the gross margins?

Peter Dameris -- Chief Executive Officer

Well...

Rand Blazer -- President of Apex Systems

Peter, can I comment?

Peter Dameris -- Chief Executive Officer

Yes. One thought. Yes, you're right. I mean, we give you the segment.

But when we look at it deconstructed, I told you the reality that the margins move around because of the margin profile on those two lines of businesses and the perm contribution, etc. Go ahead, Rand.

Rand Blazer -- President of Apex Systems

Mark, I was just going to point you to a few numbers that we've kind of come out with and if you've been charting us over the quarters. First of all, Apex margin improved in a quarter over a year ago in that quarter. Life Sciences margin held very steady. The growth rate for the Life Sciences business, if you look at the last four quarters, is crescendoing up.

So this is really all about serving clients and having critical mass to be close proximity to the client and the wherewithal to deliver the skills needed, whether they're clinical, Life Sciences or IT skills. So I think you see it in our numbers. If you looked at it quarter to quarter to quarter, what we're getting is better client service, better flow of business, better response to that business and very consistent gross margins and now improved growth rates in our Life Sciences business.

Mark Marcon -- R.W. Baird -- Analyst

Yes, it all sounds positive. I was just trying to figure out if there might be some more SG&A leverage just as you integrate things a little bit more together.

Ed Pierce -- Chief Financial Officer

The SG&A has been going on now for really a couple of years. So as I said in my comments, we integrated that two years ago. They're on common platform, common systems, common applicant tracking. So that's pretty much already shared, which made this transition really smooth and almost noneventful.

Peter Dameris -- Chief Executive Officer

And we've recycled some of that savings into investment and headcount. So it's not like we're bringing it all to the bottom line. Some of it is offsetting some of the top line -- top, the growth in our headcount.

Ed Pierce -- Chief Financial Officer

Headcount, right.

Mark Marcon -- R.W. Baird -- Analyst

And then on to Creative Circle, that continues to perform really well. What are you hearing from clients? How should we think about some of the early discussions about budgets and how they are thinking about things beyond this quarter and what they're seeing?

Peter Dameris -- Chief Executive Officer

Rand?

Rand Blazer -- President of Apex Systems

Well, I'm not sure how to answer that, Mark. I mean, even as good as we are, we don't have a crystal ball on the IT spend in our customer base always. For our bigger accounts, we do, which is really what's happened with Creative Circle. We've added to it, which has always been a very strong business.

We've added to it a top accounts program, so we're working with more of the bigger guys in their programs where we do get a little bit more visibility in what they're thinking and what they're doing around creative marketing. So I think it's a good broadening of the portfolio of accounts we have in that business. And the more and more we do that, the more we become more stable and more consistent in our performance.

Mark Marcon -- R.W. Baird -- Analyst

OK. Great. And then on DHA, it generated about $50 million in revenue in 2018. Is that growth rate consistent with what you're seeing across ECS in terms of what we should expect over the coming year? And how will that end up impacting the EBITDA margins and the gross margins for that line?

Peter Dameris -- Chief Executive Officer

Yes. So we told you when we announced the transaction, $50 million in kind of trailing, our 12/31/18 revenue and about a 20% top-line growth rate, which is higher than ECS, it's a smaller piece of business. And their EBITDA margin, we gave you a range of 8% to 9% for DHA, and that's a little bit less than ECS, and that's because their gross margin is a little bit less than ECS. And we think -- George, you can address it, that we can positively impact that over a term of time.

George?

George Wilson -- President of ECS

Yes. Sure, Peter. Yes, it's a great company, it's got great customer relationships. We looked at their contract mix.

Their contract mix is time and materials, fixed price, and we do believe that we can walk that margin up a little bit.

Mark Marcon -- R.W. Baird -- Analyst

Great. Thanks.

Operator

OK. Thank you. [Operator instructions] And we'll go to the line of Tobey Sommer with SunTrust. Please go ahead.

Tobey Sommer -- SunTrust Robinson Humphrey -- Analyst

Thanks. Peter, in your prepared remarks, you mentioned some favorable legislation. Could you talk to us about what legislation you're pointing to? What effects have been felt in the market and/or maybe you expect to feel in the market on a prospective basis?

Peter Dameris -- Chief Executive Officer

Well, it's not necessarily anything that's happened in the last 30, 60 days. But as you know, the focus on H-1B visa and appropriately applying the existing immigration laws to make sure that we're bringing in people on prevailing wages, there's tighter compliance with that, which means people are not doing a wage arbitrage with offshore labor versus domestic labor as easily and domestic laborers being used more. The whole shared resource, gig economy, people continuing to try to turn human capital into a variable cost versus a fixed cost, ensuring a resource to get 100% productivity. And there is, with the tax law changes last year, the government has to continue to find revenues.

And the biggest source of lost revenue for the government is misclassification of employees. So state and federal agencies are more vigilant about making sure that employee status is accurate. So if somebody wants to share a resource, the truly, the legal way to do it, is through us or a company like ours or a consulting shop, where we're the W-2 employer of record and paying those required taxes into the governments versus trying to find someone off the Internet to work as a 1099. And that has driven business our way as well.

And I firmly believe that will continue.

Tobey Sommer -- SunTrust Robinson Humphrey -- Analyst

Thanks. Are you experiencing that change -- or that impact more your statement of work business or staffing? Is it -- is this on the edge that you get in a couple basis points faster growth or is it percentage points?

Peter Dameris -- Chief Executive Officer

Well, I can't quantify that at this point for you. And I don't know -- we have the data. I'll see if it's appropriate to give it on an ongoing basis. But no, I mean, look, it depends on the sophistication of the customer, the buyer.

It also depends on the type of work. Is it creative? Is it digital? Is it IT? And so all these things are having an impact. Whether it's immigration, whether it's wage hour compliance, those are all having an impact of, one, domestic labor, and two, using a resource where someone is paying taxes.

Tobey Sommer -- SunTrust Robinson Humphrey -- Analyst

Great. In terms of the government business, I was wondering what your perspective is on more product and solutions in that area to build an even higher margin business because you're active and you're in a services business that is above-industry margin. Kind of the only way to keep going from there might be a bigger proportion of products and solutions.

Peter Dameris -- Chief Executive Officer

Yes. So I'll go first, but if you're trying to draw comparison to what CACI recently did, which was a wonderful company, where they're actually building and selling a proprietary product, I really don't think that's where we're going to be. We're going to remain a service provider. I think it's a big market that's not going away.

We do have to buy software which enables the solutions that we may develop and/or operate for the customer. But us building a proprietary radar or missile defense and then selling that as a product to the army, that's not what we're really going. And I think you'd be surprised if we ever announced it. George, do you want to add?

George Wilson -- President of ECS

Yes, I mean, the biggest emphasis is that we are moving a little bit higher end into -- and with that comes higher-end margins, typically, in some of our software solutions which also include a hardware component of them. So as Peter said, we're not going to go and invest and deliver a production line of new vehicles or something like that. But we are going to be delivering some pretty complex solutions that include both hardware and software. And as our hope for that, also driving more capabilities, more technical capabilities as well as a little bit higher margins.

Tobey Sommer -- SunTrust Robinson Humphrey -- Analyst

Thanks. I just had two final questions, can you give us a little color on the change in the backlog at ECS? And then could you describe to us any -- where you are in kind of cross-selling in bringing the different businesses together to market and whether that's a significant opportunity over time?

Peter Dameris -- Chief Executive Officer

George, won't you address the cross-selling kind of the rules of engagement and process that you and Apex are trying to do together. And then Ed, can you address the backlog?

George Wilson -- President of ECS

Yes, I guess, backlog first. It's been pretty simple. I mean, we've continued to maintain a very healthy backlog as we continue to win new contracts and also expand on our existing contracts. And as I mentioned in my earlier comments, we're looking like we're going to have a very strong Q1 in terms of a book-to-bill.

So we really feel comfortable about that. As far as the cross-selling, we took a little while to get integrated with ASGN and get to know Oxford and Apex. And we're moving forward with the opportunities to cross-sell, both from what was the obvious in terms of Apex providing additional resources on contracts, particularly in the high-end and harder-to-fill positions. But we're also working together to move forward and provide some of our higher-end solutions in cyber and cloud delivery to some of their commercial customers.

Tobey Sommer -- SunTrust Robinson Humphrey -- Analyst

Thank you very much.
