Good morning. My name is Kirk and I'll be your conference operator today. At this time, I'd like to welcome everyone to the Oceaneering 2015 fourth-quarter and annual earnings conference call. (Operator Instructions). Thank you.
Suzanne Spera, you may begin your conference.
Suzanne Spera - Director of IR
Thank you, Kirk. Good morning, and welcome to the Oceaneering fourth-quarter and full-year 2015 results conference call. Today's call is being webcast, and a replay will be available on Oceaneering's website. Joining us on the call are Kevin McEvoy, Chief Executive Officer, who will be providing our prepared comments; Alan Curtis, Senior Vice President and Chief Financial Officer; and Marvin Migura, Senior Vice President.
Before we begin, I'd just like to remind you that the remarks we will be making during the course of this call regarding our earnings guidance, business strategy, plans for future operations, and industry conditions are forward-looking statements, made pursuant to the Safe Harbor provisions of the Private Securities Litigation Reform Act of 1995.
Our comments today also include non-GAAP financials measures. Additional details and reconciliations to the most directly comparable GAAP financial measures can be found in our fourth-quarter press release. We welcome your questions after the prepared statements.
I will now turn the call over to Kevin.
Kevin McEvoy - CEO
Good morning, and thanks for joining us. We appreciate your participation today and your continued interest in Oceaneering. 2015 was a tough year, and global market conditions are not likely to improve over the course of 2016. While we cannot affect the macro environment we find ourselves in today, we are focused on the reality of the current market, and are making changes necessary to manage through the downturn.
So rather than beginning my comments outlining the reasons why our earnings in 2015 were less than the record we achieved in 2014, I would like to briefly highlight our cash flow generating capabilities and liquidity, which we feel set us apart from many companies in the oilfield service space.
Despite declining earnings, our annual free cash flow increased year-over-year, as we reduced organic capital expenditures and working capital. In 2015, we generated free cash flow of $360 million or 127% of adjusted net income, exceeding the $335 million we made in 2014. We had $385 million in cash at the end of the year, and $500 million available under our revolving credit facility. I will talk more about our 2016 cash flow later during the call.
Moving on to our earnings results, our fourth-quarter adjusted earnings per share was $0.58, excluding the $45.9 million impact of pre-tax adjustments and foreign currency losses, and was within the guidance range we gave last quarter. Annual adjusted earnings per share, excluding the $81.1 million impact of pre-tax adjustments and foreign currency losses, was $2.87 a share, down 28% from our 2014 results.
We have undertaken a series of initiatives to align our operations with current and anticipated declines in activity and pricing levels. Given these conditions, we unfortunately found it necessary to reduce our workforce, incur unusual expenses, and make certain accounting adjustments. With our limited market visibility on how weak 2016 may actually be, we are not prepared to quantify the magnitude or the duration of the decline, or give annual and quarterly EPS guidance.
Looking at our business operations on an adjusted basis for 2015 compared to 2014, ROV operating income declined 32% on 24% less revenue, driven by lower demand for drill support services and an 11% reduction in average revenue per day on hire. Our annual ROV fleet utilization of 69% fell from 83% in 2014.
Our days on hire decreased by 15% to about 83,800 days. Average revenue per day on hire of $9,634 was down due to an unfavorable change in geographic mix, a weakening of about 22% in the average Norwegian kroner exchange rate relative to the US dollar, and lower pricing and customer discounts.
During the year, we added 16 vehicles, retired 36 older systems, and transferred one to AdTech. The net effect of this decreased our fleet size to 315 vehicles compared to 336 at the beginning of the year. We retired a large number of vehicles during 2015, due to low market demand and limited prospective future work. Due to actions we took to control costs, operating margin only dropped to 27% from 30% in 2014.
We believe we continued to be the largest ROV owner, with an estimated 31% of the industry's work class vehicles at year-end. We remain the primary provider of ROV drill support service at the end of 2015. Of the 216 floaters under contract, we had ROVs on 118, or 55%, which is nearly 3 times that of the second-largest supplier. At the end of 2014, we had ROVs on 162 of the 275 contracted floaters, or 59%.
The calculated 4% decline in our market share of contracted rates year-over-year was not due to competitors replacing us on contracted rigs. It was simply a function of which rigs were idled during 2015.
Subsea products operating income was down 27% in 2015, relative to 2014, on a 23% reduction of revenue due to lower demand and pricing for tooling and subsea hardware, and lower umbilical plant throughput. Umbilical revenue as a percent of our total subsea products revenue in 2015 was 33%, about the same as the 32% in 2014.
Our year-end subsea products backlog was $652 million, down from $690 million at the end of 2014. This backlog decline was related to tooling and subsea hardware. Products book-to-bill ratio for the year was 0.96.
For subsea projects, considering the oil price environment and the current global oversupply of vessels, operating income held up relatively well during 2015 due to an increase in diving activity offshore Angola and in the Gulf of Mexico, and a higher profit contribution from our data solutions group.
The decline of 12% was due to lower deepwater vessel activity and market pricing offshore Angola and in the US Gulf of Mexico. Within subsea projects during 2015, we commenced work on a two-year multi-service vessel charter agreement with Shell Offshore for use of the Ocean Alliance in the Gulf of Mexico that started January 1. We experienced a reduction in pricing and work for BP offshore Angola, including the release of the Bourbon Evolution 803 that occurred at the end of April.
We secured a two-year subsea field support vessel services contract with an oil and gas company in India for use on the Island Pride. With this contract, which commenced in November, we expanded our international subsea projects business while reducing our vessel charter exposure to the Gulf, which is predominantly a spot or call-out demand market.
Last April we acquired C&C Technologies, recently renamed Oceaneering Survey Services, a global provider of survey and satellite-based positioning services. Included within this acquisition were customized, state-of-the-art, autonomous underwater vehicles, or AUVs, capable of deep ocean survey mapping.
The purchase price of $224 million was paid in cash. Due to the deteriorating market conditions, the contributions from Oceaneering Survey Services had not been what we initially expected. However, we believe having in-house survey capabilities are complementary to our existing service offerings, and will be very positive in the longer term.
Asset integrity operating income fell precipitously compared to 2014 on lower global demand and pricing for inspection services. Advanced technologies operating income for the year was substantially lower due primarily to execution issues on certain theme park projects. Unallocated expenses during 2015 were lower, mainly as a result of reduced performance-based incentive and deferred compensation expenses, as plan targets were not achieved.
While 2015 was an extremely challenging year for the industry and Oceaneering, we have taken actions to do more than just survive in this current market, but thrive and emerge even stronger than we are today. These actions focus on reducing our costs and establishing strategic partnerships with suppliers to create innovative, cost-effective solutions to maximize the value of our customers -- that our customers receive.
We are also working on ways to further differentiate ourselves with integrated solutions that offer greater customer value, especially in the areas of life of field inspection, maintenance and repair work, and decommissioning projects.
Since our comparisons have been on an adjusted basis, I'd now like to address the adjustments for the year 2015. Our results included $81.1 million of pre-tax adjustments, including $15.4 million of foreign currency losses that were primarily attributable to Angola Central Bank devaluation of the kwanza. The remaining $65.7 million of adjustments reflect our assessment of a weaker future business outlook, given the prospect that a depressed oil price environment could be prolonged.
Of this, $25 million was for restructuring expenses incurred principally as a result of workforce reductions and facility rationalization. About $12 million of these expenses were incurred prior to the fourth quarter, and were not identified earlier as being non-operating in each quarter, as these were not significant. Of the $65.7 million, $56 million affected the ROV and subsea products results.
Other than restructuring expenses, the ROV-related charges consisted of a $16 million inventory reserve, due mainly to having excess ROV umbilicals based on foreseeable market demand; and a $3 million write-off of residual book value of retired ROV systems.
For subsea products, in addition to the $9 million second-quarter inventory charge taken as a result of our decision to exit the subsea BOP controls manufacturing business, we also reserved about $11 million of other items associated with our umbilicals business. Of this, $5 million was an allowance for a doubtful account, and about $6 million was related to non-income tax credit carryforwards in Brazil that are now doubtful to be realized, due to the reduced level of expected business going forward.
Turning next to our sources and uses of cash, as mentioned previously, we had $360 million in free cash flow in 2015, as we generated $560 million of cash provided by operating activities. This amount represented the total of $231 million of net income, $241 million of depreciation and amortization, $88 million of cash reductions of working capital, less $200 million of organic capital expenditures.
Our total capital allocation spending was $650 million compared to $1.1 billion in 2014. We invested $200 million in organic capital expenditures, and $244 million on other investments. We also paid $106 million in cash dividends, and spent $100 million repurchasing 2 million shares of our common stock. These uses of cash were funded by our cash from operating activities, a decrease in cash of $45 million, and an increase in debt of $50 million.
Looking ahead to 2016, and for illustration purposes only, at an earnings level of $1 per share, we would generate about $100 million of net income after $240 million of depreciation and amortization. Before considering any changes in working capital or other sources of cash, our cash provided by operating activities would be $340 million.
Assuming organic capital expenditures ranging from $150 million to $200 million, our free cash flow would be $140 million to $190 million. This should be more than adequate to fund our anticipated $106 million in dividend payments, and make additional investments or stock repurchases.
For modeling purposes, we believe it is fair to assume that for every $0.10 of EPS above or below the $1 EPS is used in the foregoing illustration, the impact on free cash flow would be approximately $10 million.
For 2016, our organic capital expenditures are expected to range from $150 million to $200 million, and includes $75 million in maintenance capital and some uncompleted project CapEx carried over from 2015. The carryover relates mainly to the completion of the Jones Act vessel Ocean Evolution, several bespoke ROVs for which we have firm contracts, and additional equipment for our IWOCS service fleet.
In addition to funding our organic capital expenditures, we expect to continue the quarterly cash dividend of $0.27 a share. We may, however, revisit our quarterly dividend should market conditions deteriorate to the extent that our projected annual net income would not exceed the current annual dividend.
I would like to reiterate the keywords to this statement. We wrote in our earnings release, and we're saying again today, we may revisit our quarterly dividend amount of $0.27 per share if our projected annual net income amount does not exceed this annualized dividend amount. We did not write, nor did we say, that we will lower our quarterly dividend rate in such instance. We simply stated that we might revisit the quarterly dividend amount if our annual projected earnings fall below the implied $1.08 a share.
We chose our words carefully, understanding this might be one of the focal points of our earnings release and this call. While, today, we may not think this to be a likely case in 2016, we have learned from other service companies and customers alike to never say never, especially when it comes to maintaining the dividend rate; at least not in this environment, when everyone, including representatives of most of the sell-side firms listening today, have continuously revisited and lowered the expected average price of oil in 2016 and the expected level of spending by our customers.
Today we are living in a time of almost unprecedented uncertainty. However, I think we have indicated our commitment to our current cash dividend to the highest extent possible, or at least reasonable.
Our other uses of capital may be to fund acquisitions or buy back shares. We will consider acquisitions that augment our services and product offerings or add technologies. With respect to share repurchases, at the end of 2015, we had authorization to repurchase an additional 8 million shares. We intend to continue our practice of announcing share repurchases only after they occur.
Turning to our outlook for 2016, we are expecting lower demand for our services and products and renewed pricing pressure and spending cuts from our customers. Consequently, we are projecting that each of our oilfield segments will have lower operating income in 2016 than in 2015.
Directionally, for our business operations, we see ROV results being down on declining demand, notably in the US Gulf of Mexico, for drill support in vessel-based work, and lower average revenue per day on hire. Subsea products results are expected to decline on lower pricing and a reduction in umbilical plant throughput and reduced demand for subsea hardware.
Subsea projects results should reflect lower deepwater vessel demand and diving activity offshore Angola, primarily due to the release of the Bourbon Evolution 803 in April 2015, and the recently announced release of the Bourbon Oceanteam 101 at the end of May 2016.
With respect to the financial impact due to the charter cancellation, we cannot comment on the confidential contract terms for any one vessel. This was only one part of the ongoing demand destruction occurring in this extremely low oil price environment. Project management, engineering, and vessel services work associated with the provision of the remaining chartered vessel, Oceaneering Intervention III, is expected to continue as previously contracted with BP Offshore Angola through January of 2017.
This year in the Gulf of Mexico, the term charter for the vessel Olympic Intervention IV, expires in July. And the charter for the Normand Flower expires in December. We have the option to renew these charters, or let them expire and release one or both of these vessels.
Due to further shipyard delays, delivery of our subsea support vessel, the Ocean Evolution, is expected to occur late in the fourth quarter.
For asset integrity, we expect results being down on continued lower global demand and pricing for inspection services. For our non-oilfield segment, advanced technologies, operating income should improve due to expected better execution on theme park projects and increased activity. On a year-over-year basis, we expect higher unallocated expenses due to provisions for increased performance-based incentive and deferred compensation.
Turning to our first-quarter 2016 outlook, we anticipate that our earnings for the first quarter will be down considerably when compared to the first quarter of 2015, and adjusted fourth quarter of 2015. Compared to the first quarter of 2015, we expect each of our operating segments will have lower income, led by ROVs, on declining demand and average revenue per day on hire.
Subsea products operating income is expected to be lower on reduced demand and pricing for tooling, IWOCS, and subsea hardware.
Subsea projects operating income is expected to be down, mainly due to the release of the Bourbon Evolution 803 offshore Angola at the end of April 2015, and the regulatory inspection drydock on the Ocean Alliance in the US Gulf of Mexico during the first quarter of 2016.
Compared to the adjusted fourth quarter of 2015, we expect each of our oilfield segments to have lower income -- led by subsea products -- on reduced demand and pricing for subsea hardware, a drop in demand for IWOCS services, and lower umbilical plant throughput.
ROV operating income is anticipated to be down on declining demand and average revenue per day on hire.
For our first-quarter 2016 outlook, we anticipate that unallocated expenses will be lower than the first quarter of 2015, but higher than the fourth quarter of 2014. The sequential increase is attributable to accruals for 2016 incentive and deferred compensation plans compared to the 2015 accruals, which were adjusted downward.
In conclusion, near-term, we believe our liquidity and cash flow generating capabilities provide us with ample resources to manage our business through the backdrop of market uncertainty, falling energy prices, and reduced demand for our services and products.
Longer-term, deepwater is still expected to continue to play a critical role in global supply oil growth required to replace depletion and meet projected demand. Major deepwater projects remain key long-term growth drivers within international oil company portfolios. In the medium-term, we believe there will be an uptick in demand for products and services to extend the producing life of existing offshore fields, and to perform decommissioning work.
Consequently, we intend to continue in our strategy to maintain or grow our market positions, and to be prepared to expand our services and product line offerings should suitable opportunities emerge. We believe our seasoned management team, financial strength, and cash flow generating capabilities position us well to manage through this downturn.
Thank you very much. We'll now be happy to take any questions you may have.

(Operator Instructions). Ole Slorer, Morgan Stanley.
Ole Slorer - Analyst
Certainly a resilient performance. When you think about your ROV outlook in 2016, is there any reason why, at least, the volume or activity volume -- let's forget about prices for a second -- should trend materially different to that of the overall global floater rig count?
Kevin McEvoy - CEO
No, I would say not.
Ole Slorer - Analyst
So no real changes in market share, so anything like that?
Kevin McEvoy - CEO
Well, we don't see that. Really, what we've been seeing is just a drop-off of contracted drilling rigs. And if we're on them, then that's out of our mix. If we're not on them, then it doesn't affect us. But I think the general trend seems to be that this certainly could continue to some extent through 2016. And what the new equilibrium number of contracted and working floating rigs is going to be, I don't think anyone knows yet.
Marvin Migura - SVP
Ole, this is Marvin. I think the same thing applies to our vessel-based services. That seems to be dropping commensurately with the rig activity. So we see no significant shift in mix, and we don't know where the bottom is yet.
Ole Slorer - Analyst
And my follow-up would be, when you look at prices, you talked about price weakness. But when I look at your revenue, it seems to in the fourth quarter have been relatively modest, and offset by internal cost reductions. Do you think that will be more difficult to mitigate the price discounts going forward, or price reductions relative to your own cost structure? Or should we expect them to continue to be relatively balanced?
Kevin McEvoy - CEO
It's going to be increasingly more difficult for us to find cost savings to offset the potential future discounts or rate-cutting that are being demanded by our customers. I think as their situation does not improve, they're getting directives from their leaders to go back and renegotiate some more. And so, we're seeing this pretty consistently. I think everybody in our space is seeing this. And so, we expect that to continue until there is some stabilization in the price.
Marvin Migura - SVP
And that comment cuts across all of our oilfield segments.
Kevin McEvoy - CEO
Sure.
Marvin Migura - SVP
Not just ROVs.
Kevin McEvoy - CEO
Right.
Ole Slorer - Analyst
I suppose a little difference between you guys and a number of other North American guys is that you are still making money, which is a good thing. But with that, I'll hand it back. Thanks for the clarification.
Operator
Chase Mulvehill, SunTrust.
Chase Mulvehill - Analyst
The first question: on the subsea products side, maybe you could help us with your umbilicals exposure here, and then how much of your 2015 subsea products revenues were generated from umbilicals? I think you give us that number last year.
Kevin McEvoy - CEO
We gave it in the comments here. It was 33% versus 32% last year.
Chase Mulvehill - Analyst
So 33% this year. Okay.
Kevin McEvoy - CEO
In 2015, umbilicals represented 33% of the subsea products revenue. And in prior year, 2014, it was 32%.
Chase Mulvehill - Analyst
Okay. And the margin profile on the umbilicals, 2014 versus 2015, were there any material difference in margins for umbilicals?
Kevin McEvoy - CEO
Margins for everything were going down in 2015 relative to 2014. And we have previously stated, pretty consistently, that the umbilical business has more challenging margins than the other subsegments in the product segment. And so, yes, like everything, there is continued pressure on margins. Before the downturn, there was twice the capacity, roughly, than demand, and that has only gotten a lot worse.
Chase Mulvehill - Analyst
Okay. But umbilical margins are positive, right? From an EBIT basis.
Kevin McEvoy - CEO
Yes, yes.
Marvin Migura - SVP
And that's about all that we're going to say on subsegment margins.
Chase Mulvehill - Analyst
Got it, got it, okay. And real quick, on ROVs, can you just talk to the competitive landscape on the drilling support side of the business?
Kevin McEvoy - CEO
We really haven't seen much on the competitive side, for the reason that rigs are dropping off, and not much is coming on. So there really hasn't been much to say there. It's all directly with the oil companies coming back and wanting concessions.
Marvin Migura - SVP
Chase, I think we addressed that on the call, when Kevin said that we really hadn't lost much market, or any market share; that the decline in the number of rigs that we are on, as a percentage of contracted rigs, was simply a function of which rigs were idled during 2015.
Chase Mulvehill - Analyst
Okay. All right. One last one, and then I'll turn it back over. Is there any chance you could give us D&A for the ROV segment for fourth-quarter 2015?
Marvin Migura - SVP
No, I don't -- we'll do it for the year in the K, and I don't have that with me right now, Chase.
Chase Mulvehill - Analyst
Okay. All righty. Thought I'd give it a shot. Thanks.
Operator
Jim Wicklund, Credit Suisse.
Jim Wicklund - Analyst
Not a whole lot of things to ask, other than how deep is the abyss? And nobody knows.
Kevin McEvoy - CEO
(laughter) Thank you for answering your own question.
Jim Wicklund - Analyst
There you go. So why don't you just put the Company up for sale and say, the hell with it? Let consolidation take place -- always happens at the bottom of the cycle -- and move on?
Kevin McEvoy - CEO
I'll pass on that one.
Marvin Migura - SVP
Why don't you answer that one too, Jim? (laughter)
Jim Wicklund - Analyst
Well, about one in three investors asked, when is Oceaneering going to sell? I remember at our Christmas lunch, Kev, we talked about how we couldn't come up with anybody who would make sense. But I just thought I'd ask the question in public, and get it out of the way.
Kevin McEvoy - CEO
Okay.
Jim Wicklund - Analyst
Has the market become noticeably worse in the last two months? I'm getting the impression from talking to people -- whether it's bank stress or activity; and I'm hearing from board members that the managements are always optimistic. But board members seem to be taking their liability much more seriously in the last couple of months. Has there been a change, or is this just because we're in 2016?
Kevin McEvoy - CEO
I think it's important to separate out the segments we're talking about. There's doom and gloom everywhere. But there's a lot of stress, I think, on the onshore side generally across the board, whereas in the offshore segment maybe it's a lot more focused on things that float. Not necessarily everybody else's business is going down the tubes, or anything. But I think there's -- the longer that this goes on, the more negative discussion there is in the press about everything. And so you're going to feel worse about it. But certainly anybody on a board of a company in this business ought to be paying attention to what is going on.
There are companies that can't borrow more money. There's all kinds of stress out there. And that's why we thought it would be prudent to highlight the fact that we, thankfully, at this moment in time, and as far as we can see at the minute, are not in that situation and should be able to weather the storm, as they say.
Jim Wicklund - Analyst
Okay. And unprecedented uncertainty -- you guys were the last guys standing for the last year to give guidance. Was it a decision that didn't do you any good, or you couldn't come up with anything credible -- too much uncertainty to even give broad guidance, because in the past you've given ranges?
Kevin McEvoy - CEO
Well, I think that we -- and last year, it was in October, and I think things were really just starting to happen. And we did not appreciate, and I think many other people did not either, at that time, which is when we historically give the guidance for the following year. So, we just did not see what was coming. And you're right; we certainly got no credit for it. We got beaten up for it a lot more than people that didn't give any guidance.
Jim Wicklund - Analyst
True.
Kevin McEvoy - CEO
And I think we -- well, anyway. So, there did not seem to be any upside to try to give guidance. It would have had to be so broad a range that no one would account it for anything. And to the last point, it is pretty unclear out there what it's going to be. We are primarily in a spot market kind of business, and [FIG] of new projects is not really happening. And so there's just a heck of a lot of uncertainty.
Marvin Migura - SVP
And we've seen that term contracts for rigs, boats, whatever -- (multiple speakers)
Jim Wicklund - Analyst
Don't mean much.
Marvin Migura - SVP
-- put it on. So it would be really-- I think the answer to question was both.
Jim Wicklund - Analyst
Okay. Well, I think it's good that you all don't get guidance. Like I say, you didn't get credit for it. Gentlemen, thanks. All the best.
Operator
Kurt Hallead, RBC.
Kurt Hallead - Analyst
I had a question on the ROV dynamics, specifically on the cost front. Can you give us some general sense as to variability on ROV cost? When I go back and look over time, there has been some upward movement in the working cost of the ROV over time. But as activity is coming down and there are fewer ROVs working, I'm thinking that the ROV cost is going to come down as well. So, just looking for some fixed versus variable on your ROV cost structure.
Kevin McEvoy - CEO
Well, the cost structure is different, depending on the geographic area that we're working. Because in some places, you've got unions and the labor costs and it can be pretty variable. The system cost is fungible. It doesn't really care where it's working. I don't know if that answers your question or not.
Marvin Migura - SVP
Kurt, I think our costs, relative to anything else that we have, our ROV costs are variable because of all of the crew members go home when the rig -- and when the system is idle. So that has always been a variable cost, up or down. And R&M stops when the ROV -- when the system goes idle.
What continues and becomes a bigger part of the cost and lower utilization is the onshore cost and depreciation. So that's fixed. When you look at -- we have a high degree of variability in direct cost as it relates to crew labor and depreciation. And the costs are much less variable when it deals with shored-based cost, and depreciation is not.
In shore-based cost, for example, we still have to keep the shore base open if it's four systems running or 12 systems running. We could reduce the people. But you still got the rent; you still got the facility cost; and you still have some people. So I hope that addresses it.
Kurt Hallead - Analyst
Okay. Yes, that's helpful, thanks. And then on subsea products, also wanted to get a handle on the resiliency in that business, because there's elements of it that our backlog-driven, right? And there are elements of projects that are still moving forward. And you probably have some good sense on what margins are in backlog.
So, any color around the resiliency of subsea products, or helping us get a greater understanding and knowledge of how that business may fare, as we go into a downturn here?
Kevin McEvoy - CEO
Well, I think we gave the backlog number, which is primarily umbilical-denominated. The rest of it is pretty short-cycle stuff, and so pretty hard to say what that's going to be. And obviously through this year and into next year, everybody is going to be looking at -- are there any new orders for umbilicals for projects that, A, may have already been sanctioned, or B, are expected to be sanctioned? Does that happen or not, or do they continue to slide to the right, or what's going to go on there? So I think it's a moving target.
Kurt Hallead - Analyst
Okay. Appreciate that. Thanks for that, guys.
Operator
Waqar Syed, Goldman Sachs.
Waqar Syed - Analyst
Kevin, in the advanced technology business, should we think about the first half of 2016 to look similar to the first half of 2015, or things are different there, too?
Kevin McEvoy - CEO
Well, we hope what is going to be different is better execution on some of these theme park projects. But hang on one second; we're just trying to look at our --.
Waqar Syed - Analyst
Your first half of 2015 was actually pretty good.
Kevin McEvoy - CEO
Sorry?
Waqar Syed - Analyst
First half of 2015 was pretty good for you guys, in advanced technologies.
Marvin Migura - SVP
Waqar, it looks like -- our crystal ball tells us that the first half is going to be a little lighter, and then the second half is going to be much stronger.
Kevin McEvoy - CEO
And I think that there is a mix, if you will, for a lot more engineering work in the first half. And then we'll go into project execution in the second half, which will generate more revenue.
Marvin Migura - SVP
Because as Kevin mentioned on the call, on the prepared comments, we're expecting advanced technologies to improve for two reasons. One of them is better execution, and the second is increased activity. And as Kevin said, that increased activity starts, but in the beginning of a project there's more engineering. And then when you actually get into the commencement of the work, that's when you have more revenue recognition and profits.
Waqar Syed - Analyst
Okay. Now, on the ROV side, many of the contracts for the drilling rigs are being terminated early. But the drilling contractors generally, as per contract, receive early contract termination revenues. Do you have any provision like that in your ROV contracts, especially for the ROV that you've built for newbuilds?
Kevin McEvoy - CEO
Generally we do not, other than the obligation for them to reimburse us for the cost of demobilization, should we choose to do that.
Marvin Migura - SVP
I think that's consistent with most of the service companies that go on rigs. We are really tied to the -- whether or not the rig is working. And terminations seem to go to the real high capital-asset-intensive companies, and we don't fall into that category.
Waqar Syed - Analyst
Okay. And then off your one-time items that you broke out for the fourth quarter, could you guide us which item is allocated to G&A and which is to DD&A, and what goes to the cost of goods sold?
Marvin Migura - SVP
Okay. Waqar, I'm going to try this from the top of my head. $3 million of the ROV write-downs for the retired systems went to DD&A. The -- whatever it was, $5 million associated with the allowance for doubtful account with a small independent operator in the North Sea on an umbilical contract, and that went to G&A. Because it was not a performance issue; it was a collectability issue.
And the only thing that's very hard to do is restructuring expenses of -- there were $14 million of it in Q4. It is spread all over the place. It is spread in -- not in DD&A -- but it is primarily in direct costs, cost of goods sold. But there is some of that element in G&A. And I can't figure that out. I just don't know. I don't have that detail.
Waqar Syed - Analyst
So what would your guidance be for G&A for first-quarter 2016?
Kevin McEvoy - CEO
We're not giving guidance, Waqar (laughter).
Waqar Syed - Analyst
No, because there's just so many -- we don't know what underlying G&A is for the fourth-quarter 2015. So it's a little bit harder to project for first-quarter 2016, so that's why I'm asking.
Marvin Migura - SVP
No, I appreciate that. Let me say that I think from -- year-over-year, we will be down. We will have a lower G&A in 2016 than we had in 2015.
Waqar Syed - Analyst
Okay.
Marvin Migura - SVP
That should spread pretty -- not evenly; I don't know that -- but I'm just saying, we are expecting that some of it -- I mean, we had costs in the numbers that were associated with the two things that I mentioned, restructuring and the allowance for doubtful accounts. So that should come out. And then the cost savings of the steps we have taken to reduce our fixed costs, or G&A costs, all costs, we should be able to notice that impact in 2016. But it's really going to depend. Part of that question is, what's our run rate going to be? And that's why it's really hard to give a more definitive answer, just other than down.
Waqar Syed - Analyst
Okay. And how many ROVs are you planning to build in 2016? And I apologize if you already mentioned that in the prepared remarks.
Kevin McEvoy - CEO
The only ROVs that we're going to build are something that is bespoke, as we mentioned in the call notes, that we have a specific contract to provide. And we're talking mid-single-digit numbers for something like that.
Waqar Syed - Analyst
And how many do you plan to retire?
Kevin McEvoy - CEO
Well, we don't predict it. I think we --
Marvin Migura - SVP
Same number. 3% or 4% is kind of standard answer. But again, it really is going to -- you can tell that we have retired a bunch more than that in Q4. There's not much impact at all to a retired system. Usually it's fully depreciated, and it hasn't worked for a while.
Waqar Syed - Analyst
Okay. And, Kevin, in the past you've mentioned that maintenance activity has been slow. Are you seeing any signs that [2016] people will need to pick that up?
Kevin McEvoy - CEO
Not yet.
Waqar Syed - Analyst
Not yet?
Kevin McEvoy - CEO
No.
Waqar Syed - Analyst
All right, so that's all I have. Thank you very much.
Operator
Dave Wilson, Howard Weil.
Dave Wilson - Analyst
Just some clarifications: one on the initiatives and aligning the operations with the current environment. Are you done with that? Or do you think that will be done in the first quarter, or is there more to go from here?
Kevin McEvoy - CEO
I think we are continuing to work on this. As the market continues to change downward, or until that stops, we're going to have to keep doing this.
Dave Wilson - Analyst
Got you.
Kevin McEvoy - CEO
Figure out what we could do.
Marvin Migura - SVP
Right. And I think (multiple speakers) that were noted in Q4, we do expect most of those to be completed in Q1.
Dave Wilson - Analyst
Okay. And then a follow-up on the 25 ROVs that were retired in the fourth quarter. Can you give us a broad breakout of when's the last time those ROVs were actually in service and working? I know that you said, previously, it's been a while. But where any of those actually working in the fourth quarter that got retired in the fourth quarter?
Kevin McEvoy - CEO
No.
Marvin Migura - SVP
No, no.
Kevin McEvoy - CEO
We can answer that question, Dave. No.
Dave Wilson - Analyst
Okay, great. And then one final one, and I apologize if I missed it and going over the limit here on two. But the breakout between drilling support and vessel support in terms of percentages, I might have missed that if you all gave that.
Marvin Migura - SVP
We did, I think. Yes, Alan, go ahead. Give it. Okay. Give me one second.
Dave Wilson - Analyst
Sure.
Marvin Migura - SVP
We didn't give it (multiple speakers). We did not give it. Suzanne knows, so we'll look that up. Go to the next question, and we'll get back to it.
Suzanne Spera - Director of IR
For the year?
Marvin Migura - SVP
(multiple speakers) for the years, got it.
Suzanne Spera - Director of IR
For the year, drill support was 68%, and vessel support was 32%.
Kevin McEvoy - CEO
(multiple speakers) Okay?
Dave Wilson - Analyst
Okay. I can figure out the rest. Thank you very much.
Operator
Marc Bianchi, Cowen.
Marc Bianchi - Analyst
Back to the line of questioning I think Kurt was asking on the ROV side, just trying to understand the operating leverage there a little better. Just looking at the experience in the fourth quarter, is that -- should we think about the operating leverage that was produced in the fourth quarter as normal? So, with a 12% decline in activity and flat pricing would produce that kind of a margin change?
Marvin Migura - SVP
Hi, Marc. That's a really difficult question when we're talking about no visibility in the utilization as to knowing what -- all we read about is how many rigs are coming off in the Gulf of Mexico over the next quarter or next six months, whatever. And I don't think -- and as Kevin mentioned, renewed pricing pressure from everybody. So, I don't know if it's repeatable. I don't know how to answer that question.
Alan Curtis - SVP and CFO
I think Kevin also spoke to the fact it's going to be harder and harder to take the cost when we are (multiple speakers) decreases in pricing. So the answer is, it's really difficult.
Marc Bianchi - Analyst
Okay. That's all I had. Thank you.
Operator
George O'Leary, Tudor, Pickering, Holt & Company.
George O'Leary - Analyst
Just one for me, given all the questions that have been asked already. Could you maybe help frame your prospects for 2016? And I know you're not giving explicit guidance, but just maybe compare and contrast the prospects you see for your ROV business and subsea projects. And regarding the latter, is there potentially more pressure on that business, given the call-out nature of the Gulf of Mexico business in particular?
Kevin McEvoy - CEO
Well, I think as long as we are continuing in this downward trend, there is going to be increasing pricing pressure, particularly the vessel-based activity that's not on a term contract. That's a mark-to-market, every time they pick up the phone and call you. And those margins are eroding as time goes on. And there's an oversupply of vessels out there trying to get whatever work is available, so it is a very challenging market.
George O'Leary - Analyst
So maybe one tiny follow-on. That was helpful color, thanks. And I said I have one, but just something popped up while you were talking. So just generally -- would you -- maybe are you -- intervention type work is maybe at the margin under pressure, more than drilling support? Or is it more just there's too much supply and too little demand out there?
Marvin Migura - SVP
I think it's the latter. I don't think there's any pricing pressure for -- your focus on ROVs -- and Kevin was talking about projects and the intervention work ROVs are still reported in part of vessel-based services in ROVs. And I think there, it's a utilization issue more than a pricing issue of any differentiation. There's a pricing pressure everywhere. But in the call-out, vessel-based business, it is more of function of utilization.
George O'Leary - Analyst
Got it. Thanks, guys.
Operator
Ian Macpherson, Simmons.
Ian Macpherson - Analyst
I'm interested in the recent slope of the decline of activity for ROVs that was witnessed in Q4. Your days on hire were down 12% sequentially, which was a much bigger sequential drop than you had experienced during the prior several quarters since we peaked and rolled. And it was also a sequential drop that diverged from what the rig count did. The rig count didn't roll 12% quarter on quarter. And so, I'm just trying to really gauge what's going on.
And I wonder if you would be willing to share any of your middle-of-Q1 results, in terms of activity, and how it's tracking from the end of the year until now. Is it still falling sharply, or has it been a little bit more stable through the first half of (multiple speakers)?
Kevin McEvoy - CEO
Well, remember that this is historically a very seasonal business. And I think that, particularly in today's market when people are trying to not spend any money, it may be even exacerbating that phenomenon. So in terms of -- I think it's probably not a good place to go to try and compare it to the fourth quarter of last year, because everything is just so different.
I would say that seasonality is going to be a lot more prominent in the first quarter than it has been. And that's really what's going to drive it. People are trying not to spend money.
Ian Macpherson - Analyst
Okay. We'll wait and see. Can I have just two more quick follow-ups on model stuff? You said your unallocated expenses for 2016 are expected to be higher than 2015. Correct?
Marvin Migura - SVP
Yes. Because of the (multiple speakers) incentive and deferred comp plans. Yes.
Ian Macpherson - Analyst
Okay. And then lastly, in your free cash flow construct that you provided in the opening remarks, you didn't mention free cash -- sorry, release of working capital. I think we would expect that you would enjoy some release of working capital in this compressing market. Is that too optimistic to assume that will be another free cash flow tailwind?
Kevin McEvoy - CEO
No, we would expect that to happen. We were just trying to generalize, and directionally give a positive accounting of what we expect.
Marvin Migura - SVP
What we did in the illustration, Ian, is talk about a dollar. In the working capital (multiple speakers) provided. Yes, is gone -- we just ignored it, and just said, we don't need that. But if the business continues to contract like you just mentioned, then you would expect working capital reductions.
Ian Macpherson - Analyst
Got it. Thank you very much.
Operator
Ken Sill, Seaport Global Securities.
Ken Sill - Analyst
The use of the cash -- great balance sheet. You've got access to liquidity. You talk about technology acquisitions. But can you give a little bit more guidance on what -- I mean, is this subsea, or any new market potential? Or how are you guys looking at what tucks into Oceaneering out of the prospects that are out there?
Kevin McEvoy - CEO
Well, I think we said anything that complements our existing products and service lines and technology. I think, implied, is that also that would complement what we're currently doing. We added the survey leg to the stool back in April, which was a major complementary acquisition. I would not look to see us do something way out of the fairway from what we have focused on as our core businesses.
Marvin Migura - SVP
And Ken, look, a big qualifier in there, too: should suitable opportunities arise. So, no, we don't have anything in the lineup that we could talk about. We know that we're looking.
Kevin McEvoy - CEO
I think the point was that we do have the capacity and capability to entertain such a thought, which is more positive than most folks enjoy right now, I think.
Ken Sill - Analyst
Not that you want to, but I think you could buy all of the offshore [sizing] companies in the world for about $500 million.
Kevin McEvoy - CEO
(laughter) Yes, well, okay, if we wanted to.
Ken Sill - Analyst
So one other question then, and I don't know if it's too soon to say. So you've got Schlumberger buying Cameron. You've got the -- everybody is trying to look for ways to reduce the cost of subsea infrastructure [that needs to produce these deepwater fields]. Where do you see Oceaneering fitting into that? Obviously on the intervention, tooling, and stuff like that you can fit, but how do you guys plan to -- or see yourselves participating there?
Kevin McEvoy - CEO
Well, the ROV is central to everything that happens subsea, but it's just a tool. There's not much to do with it, per se. We do have ways to reduce the cost of umbilicals and connection hardware. But that really is dependent on our customers being willing to reduce their self-imposed technical requirements, in many cases.
I think the truth of the matter is that we are a pretty small part of the cost of a field development. And my perspective would be that all companies need to shorten the timeline from discovery to first oil. And going to more standardized approaches for development in general, as opposed to a particular piece of hardware, can allow them to do that. And working closer with contractors up, and down the value chain, in order to achieve that is also going to be part of it.
Ken Sill - Analyst
Okay. Thank you.

David Smith, Heikkinen Energy Advisors.
David Smith - Analyst
Just regarding the cautionary comments about potentially revisiting the dividend, based on how it compares to projected annual net income. Just hoping to get a little color, including -- does that refer to GAAP net income? Or should we just think about that compared to adjusted net income?
Kevin McEvoy - CEO
(multiple speakers) We don't have any adjustments in mind for 2016, and we don't plan for them anyway.
Marvin Migura - SVP
We're not planning for them so --.
Kevin McEvoy - CEO
Otherwise we're out of crayons.
Marvin Migura - SVP
We're thinking that the same.
David Smith - Analyst
Right, right. But just in case they weren't, I was curious to keep in mind, going forward, if we should think about that being a GAAP or adjusted.
Marvin Migura - SVP
It will depend upon, when that happens, on the type of adjustment that were going to carve out. Right now, it's the same of the intent of that -- I think Kevin clearly underscored that is we may revisit, but -- pick one. I would say yes.
David Smith - Analyst
Appreciate it. And just regarding the subsea projects, wondering if there were any particular cost items that stood out in the quarter, maybe related to the Island Pride mobilization. Because, otherwise, the flattest cost would suggest similar activity levels to last quarter.
Alan Curtis - SVP and CFO
Yes, during the Q4 comparatives, we actually did have a drydock on an Ocean Intervention vessel. And a lot of it was seasonality, as well, declining in demand for C&C survey during the quarter, as well as a decline in diving in the Gulf of Mexico. As well as we're talking about lower vessel pricing.
David Smith - Analyst
Okay. So, nothing particularly sticks out in terms of the (multiple speakers)?
Marvin Migura - SVP
Other than the drydocking.
David Smith - Analyst
Got it. Appreciate it. Thank you.
Operator
Darren Gacicia, KLR Group.
Darren Gacicia - Analyst
Broad question that I'm hoping to get specifics with it. Subsea projects, when you think about the fourth quarter, how many vessels were running? How many were owned? How many are leased in? I think I heard in your prepared comments that you could potentially -- the leases on two of them expire.
I'm just trying to sense of how to model out the earnings power of that business, just based on what the assets are. And if I need to make my own assumptions on what goes forward, though, that's fine. But it's always a tough business to break down in terms of its components. If you could help me out, that'd be great.
Marvin Migura - SVP
Darren, to clarify, you want to know how many vessels are owned, and how many are chartered?
Darren Gacicia - Analyst
Yes, and what was working in the fourth quarter. And maybe if you have thoughts on how that's progressed over the course of the year.
Kevin McEvoy - CEO
Well, we give utilization.
Marvin Migura - SVP
No, we don't get into which vessels -- we don't even see -- what we have -- let me start with the easy part. We own the smaller two of our boats, the Ocean Intervention and the Ocean Intervention II, and we charter in everything else. Except for the Ocean Intervention III in Angola and the Ocean Alliance in the Gulf of Mexico, everything is on a call-out. And the Island Pride in India. Sorry. Thank you. Forgot about that.
Alan Curtis - SVP and CFO
And the Island Pride in India.
Kevin McEvoy - CEO
Everything else is call-out.
Marvin Migura - SVP
And what worked in Q4 -- remember, Q4 and Q1, particularly, were the lowest level of activity for call-out boats because of seasonality. So, what worked in Q4 -- it's not very relevant to being able to model, and with the uncertainty of next year. And what we did point out is if we find ourselves one boat too many in July, we can reduce our costs. And then again in the very late part of the year, we have that other option to renew or not, whichever the last boat is that --.
Kevin McEvoy - CEO
The Flower, Normand Flower.
Marvin Migura - SVP
The Normand Flower. Yes, thank you. So, I don't think we can give you much more color than that.
Darren Gacicia - Analyst
Got you, okay. Well, I tried. It's a difficult business to follow, given the fact that there can be so many things on and off. With regard to ROVs, a little bit more of a -- less of a numerical, more of just a broad, how the business works question. When a rig stops working, and you take the ROV off, you demo it back to some central yard.
What happens in there? Is there a basic maintenance that happens there? And then if you were to put that same ROV back on hire, what's the lag time in terms of being able to do that? So it's really a question about cost to maintain idle ROVs, and then time to put them back to work, and what's required.
Kevin McEvoy - CEO
Well, okay. Let's try this. If the rig is a rig that we think is potentially going to go back to work again, we will leave the system on there and the maintenance pretty much stops. We can choose to send to folks out there periodically, every couple of months or something, just to turn the lights on and see if things still work or whatever. But it's de minimis cost there.
If we choose to demobilize it, typically we take it to one of our regional bases, and it is the same thing. We don't have to spend a lot of money maintaining them. And the turnaround time from an inactive ROV that was working when it went inactive, to turning it back around again to be ready for a job, is two weeks or something. It's not very much.
Darren Gacicia - Analyst
Got you. Is there any perspective in terms of what is idle now, how many have you left on the rig, versus how many have gone back to base?
Kevin McEvoy - CEO
I don't have that number off the top of my head. Generally, you can maybe look at it this way: when the rig owner says that they are cold stacking a rig, then generally that is a high probability that we take our ROV system off of there.
Darren Gacicia - Analyst
Got you. No, I appreciate the help. Thank you.
Operator
Edward Muztafago, Societe Generale.
Edward Muztafago - Analyst
Just two quick questions on the ROV business, just maybe to follow up a little bit on what Ole was talking about. We are more or less seeing an ephemeral relationship between declining ROV utilization and the idling of rigs.
Under a recovery scenario, should we expect that relationship to be largely the same? Or is the dynamic such that we would see somewhat of a lead time between an improvement in ROV utilization and working rigs?
Kevin McEvoy - CEO
I'm not exactly sure what you're asking, but it's pretty much one for one: when the rig goes back to work, the ROV is working. If it's on a short-term drilling contract, then that will obviously impact the trajectory. But if rigs start going back on year-plus charters, then you'll be able to see the corresponding increase in ROV utilization.
Marvin Migura - SVP
And if our outlook for the medium-term, as Kevin said in his remarks -- if the outlook is correct that there will be an uptick in demand for products and services to extend producing life of existing offshore fields, and performing decommissioning work, you would see -- you should see a pickup in vessel-based activity before more rigs go to work.
Edward Muztafago - Analyst
Okay.
Marvin Migura - SVP
So (technical difficulty) help our ROV utilization without an increased number of the drilling rigs.
Edward Muztafago - Analyst
Okay. So, some in the vessel-based business; not so much in the rig (multiple speakers) business. And then just --.
Kevin McEvoy - CEO
Rig base is one-for-one.
Edward Muztafago - Analyst
Yes, okay. Very helpful. And then just the follow-up: you did highlight that it's pretty difficult, probably from here forward, to offset some of the pressures on pricing with cost reductions. Is there any reason for us to think that the decremental margin performance for ROVs would be better in 2016 than it was in 2015?
Kevin McEvoy - CEO
No, I don't think so.
Edward Muztafago - Analyst
Okay. That's very helpful. Thanks.
Operator
We have no further questions at this time.
I'll turn the call back over to the presenters.
Kevin McEvoy - CEO
Okay, very good. I'd like to thank everyone for joining us, and just make a few short remarks. 2016 will likely be a very challenging time for the oilfield services industry. But we are confident in our ability to manage our business through this cycle. We intend to stay focused on our operations, organize more effectively, and further integrate our services and product offerings for more cost-effective solutions which better serve our customers. We have a strong balance sheet, and are confident in our cash flow generating capabilities.
We have been, and will continue, adapting and making changes as necessary. We have many initiatives ongoing. I would like to thank our employees and management teams for their dedication and support while embracing the challenges in a positive way and responding admirably.
