I will now give you an overview of our second-quarter results and Sam Thomas, our Chairman, President and Chief Executive Officer, will provide highlights of the operating results for each of our business segments and the outlook for 2007.
We are pleased to report that net sales for the second quarter of 2007 were $167.6 million and represent an increase of 30% compared to net sales of $129.4 million in the second quarter of 2006. Net sales for the second quarter also improved 10% over the first-quarter 2007 net sales of $152.5 million. This significant sales growth was led by our Distribution & Storage and Energy & Chemicals segments.
Our gross profit for the second quarter of 2007 was $51.3 million, or 31% of sales compared with $36.1 million or 28% of sales for the second quarter of 2006. The increase in our gross profit was primarily attributable to higher sales volume, particularly in our Energy & Chemicals and Distribution & Storage segments. Our gross profit margin improvement was primarily the result of a favorable change in project mix for the Energy & Chemicals segment that Sam will expand on.
Selling, general and administrative or SG&A expenses were $28.8 million or 17% of sales for the second quarter of 2007 compared with $17.7 million or 14% of sales for the same quarter in 2006. This increase in SG&A expenses was mainly due to $7.1 million of onetime non-cash stock-based compensation expense and $500,000 of secondary offering expenses. The stock-based compensation expense resulted primarily from the vesting of performance-based options in connection with our secondary offering completed in June. The remaining increase in SG&A expense was chiefly due to higher employee related and infrastructure costs to support growth particularly in our Energy & Chemicals and Distribution & Storage segments.
The increase was also due to public company costs related -- or incurred in 2007 including Sarbanes-Oxley implementation cost of $400,000 which will continue for 2007 and beyond. Excluding the stock-base compensation and secondary offering charges, SG&A expenses for the second quarter of 2007 would have been approximately 13% of sales.
Amortization expense for the second quarter of [2000] was $2.6 million for the comparable period of 2006, amortization expense was $3.5 million. This decrease of $900,000 was attributable to some intangible assets being fully amortized at June 30, 2007.
Net interest expense and amortization of financing costs for the second quarter of 2007 was $6.4 million and for the second quarter of 2006 was $7 million. This decrease was mainly attributable to long-term debt -- lower long-term debt outstanding as a result of voluntary principal prepayments of $55 million in mid 2006 primarily from warrant and option exercise and IPO proceeds and an additional $40 million voluntary prepayment in the second quarter of 2007, largely funded by secondary offering proceeds. The decrease in our interest expense was partially offset by higher interest rates on our senior credit facility.
Income tax expense was $4.3 million for the second quarter of 2007 and represented an annual effective rate of 34%. This compares with $2.5 million for the second quarter of 2006 which represented an annual effective tax rate of 32%. The increase in the effective tax rate in 2007 was primarily due to a greater proportion of U.S. earnings that are taxed at higher rates than our foreign earnings.
In summary, our consolidated net income for the second quarter of 2007 was $8.4 million and represented $0.32 per diluted share. Excluding the $7.6 million of onetime stock-based compensation and secondary offering expenses, our 2007 second-quarter pretax and net income would have been $20.3 million and $13.5 million respectively or $0.51 per diluted share. This compares to net income in the second quarter of 2006 of $5.3 million.
I'd also like to point out that our earnings per share for the second quarter of 2006 as reported in our financial statements is not comparable to the second quarter 2007 because of the changes in our capital structure relating to the July 2006 IPO and the June 2007 secondary offering.
Cash provided by operating activities for the six months ended June 30, 2007 was $8.4 million compared with $16.4 million for the same period in 2006. This decrease in cash provided by operations was mainly due to higher working capital levels, primarily accounts receivable and inventory to support business growth.
For the first six months of 2007, cash used in investing activities was $12.2 million compared with $23.3 million used in the same period of 2007. Capital expenditures in the first half of 2007 were $10.6 million compared to $7.2 million in 2006. This increase in capital expenditures of $3.4 million was mostly for continued strategic expansions at our Energy & Chemicals Brazed Aluminum Heat Exchanger facility in La Crosse, Wisconsin and our Distribution & Storage facility in China to support business growth.
Also $1.6 million of cash was used in the first six months of 2007 to repurchase the remaining minority interest in our Czech Republic subsidiary Chart Ferox. In 2006, $15.9 million of cash was used to acquire Cooler Service.
Cash used in financing activities was $900,000 in the first half of 2007 versus $6.9 million of cash provided by financing activities for the same period of 2006. In 2007, $38.1 million of cash was received from the exercise of the underwriters overlap and option in conjunction with our secondary stock offering and $1.3 million of cash was received from our join venture partners to fund a Chinese joint venture for the manufacture of cryogenic trailers.
Also in 2007, $40 million of cash was used to make a voluntary principal prepayment under the term loan portion of our senior credit facility. In the second quarter of 2006, $39.2 million of cash was received from the warrant and option exercises in conjunction with our IPO and $30 million of cash was used to make voluntary principal prepayments under a senior term loan and $2.4 million of cash was used to pay off other short-term debt. As a result of these activities, we ended the first six months of 2007 with $14.3 million of cash versus $18.9 million at the end of 2006.
I will now turn the call over to Sam Thomas who will review our business segment highlights for the second quarter of 2007 and provide an updated outlook for 2007.
Sam Thomas - Chairman, President and CEO
Thank you, Michael, and good morning everyone. Overall we are very pleased with our second-quarter operating results especially the improved results in our Energy & Chemicals segment. We continue to benefit from the robust demand in the markets that we serve particularly the global industrial gas market.
Our Energy & Chemicals segments, or E&C sales, improved by 37% to $58.1 million for the second quarter of 2007 compared with $42.5 million for the same quarter in the prior year. This sales growth of over $15.5 million was primarily due to the inclusion of almost $8 million of air cooled heat exchanger sales as a result of the Cooler Service's acquisition last year and higher volume for Brazed Aluminum Heat Exchangers.
E&C gross profit margin increased to 27% in the second quarter of 2007 compared with 15% in the 2006 period. This 12 percentage point increase was mainly attributable to a favorable change in project mix for process systems.
As you may recall, we had some projects in the second quarter of 2006 where we had an execution issues that significantly increased our costs, primarily the two large complex field installation projects that have diluted our gross profit margin over the past year.
I would also like to mention that E&C's gross profit margin improved almost 16 percentage points in the second quarter of 2007 compared to the first quarter of 2007 as we were able to quickly recover from the brief February strike at our La Crosse, Wisconsin facility, put several fixed-price contracts behind us where we had incurred escalating raw material and labor costs, and stabilizing the margin impact of the two large installation projects. We are continuing to work diligently with our customers to complete these two projects by the end of 2007 and we expect to maintain the existing margins on these projects until completed.
Our Distribution & Storage segment, or D&S, sales for the second quarter 2007 increased by 30% to $86.6 million. This compares with $66.5 million for the second quarter of 2006. Bulk storage and packaged gas systems sales volumes were favorably affected by the continuing growth in the global industrial gas market, price increases to absorb escalating raw material costs and to a lesser extent, foreign currency translation as a result of the weakening U.S. dollar compared to the euro and Czech koruna.
Although D&S is expecting sales growth in the second half of 2007 compared with the second half of 2006, a temporary slowdown in bulk storage tank sales in the U.S. industrial gas market is anticipated in the second half of the year primarily due to the Linde/BOC merger. This merger of two of our significant customers has resulted in what we believe is a temporary reduction in U.S. bulk storage tank activity at these customers and at Airgas, another customer that purchased part of Linde's U.S. business while they digest the change in their tank inventory levels.
We do not currently believe this development reflects any long-term trend in the U.S. bulk storage tank business. The D&S gross profit margin declined slightly to 32% in the second quarter of 2007 mostly due to a change in product sales mix.
Our BioMedical segment sales for the second quarter of 2007 improved by 12% to $22.9 million compared with $20.4 million for the same quarter in the prior year. This increase in sales was primarily due to higher volume in the international markets for biological storage systems. BioMedical gross profit margin declined to about 35% in the second quarter of 2007 which compares to 38% for the same quarter of 2006 due to a change in productline sales mix in U.S. markets and raw material surcharges. We currently anticipate these raw material surcharges to moderate in the second half of 2007.
Backlog was $415.3 million at June 30, 2007, an increase of 21% compared with the backlog of $342.2 million at March 31, 2007, an increase of 50% compared to the backlog of $276.9 million at June 30, 2006. Orders for the second quarter of 2007 were $243.5 million compared with orders for the first quarter of 2007 of $174.8 million, an increase of almost 40%.
E&C orders for the second quarter of 2007 were an impressive $145.6 million compared with the $71.3 million for the first quarter of 2007. As we reported previously, Energy World Corporation awarded us orders totaling in excess of $100 million for four LNG liquefaction trains to be installed by Energy World in Southeast Asia. E&C's backlog was $315.0 million at June 30, 2007 and represented nearly a 40% increase compared to the $226.7 million at March 31, 2007.
I would also like to mention that we recently entered into a strategic alliance with Energy World which reinforces our long-term relationship and positions us to obtain future LNG projects over the next several years.
D&S orders in the second quarter of 2007 remain consistent at $76 million compared to orders for the first quarter of 2007, reflecting continued demand in the global industrial gas market. D&S's backlog at the end of the second quarter of 2007 was $92.6 million and declined approximately 12% versus the backlog at the end of March 2007 mainly as the result of very strong sales in the second quarter.
BioMedical orders in the second quarter of 2007 were $21 million compared to orders of $26.9 million in the first quarter of 2007. This decrease in orders was primarily attributable to the timing of larger orders. BioMedical had an extremely strong order flow in the first quarter of 2007 after coming off of a slow fourth-quarter 2006.
Now I'd like to take a moment to provide you with our outlook for 2007 and explain some changes that were made in our earnings per share outlook as a result of our recent secondary stock offering. Based on our backlog performance to date and second half expectations, we are reaffirming our sales outlook range of 620 to $650 million. Our 2007 EPS outlook remains unchanged except for the impact of 1.9 million overallotment shares issued in the secondary offering and the $7.9 million of non-recurring charges incurred in connection with the secondary offering.
Our 2007 EPS range is expected to be $1.26 to $1.38 per delivered share based on 27.3 million weighted average shares outstanding. This includes the 1.9 million overallotment shares. This range also includes the $7.1 million of non-cash stock-based compensation expense and the $0.8 million secondary offering expenses previously mentioned. Our previously reported earnings per share outlook was a range of $1.54 to $1.66 per diluted shares based on 25.8 million weighted average shares outstanding and did not reflect the impact of the secondary offering just explained.
Finally, I would like to mention that for 2008 and we are currently estimating that the annual weighted average diluted shares outstanding will be approximately 29 million.
Thank you for participating in our conference call. This concludes our remarks. Operator, please open up the lines for questions and provide the participants with instructions for doing so.

(OPERATOR INSTRUCTIONS) Roger Read, Natexis Bleichroeder.
Roger Read - Analyst
Good morning, gentlemen. E&C finally looks like maybe those two projects are getting behind you in the numbers. I was wondering, Sam, could you give us an idea, is there -- and I guess you talked about this on I believe the Q1 call -- potential for those projects to come back through on a positive note in the back half of the year if you're able to recover through change orders, etc.? Does it still look like that is a possibility? Is that included in your guidance? And is there any chance left in the back half of the year for any more surprises out of those two projects or can we put those behind us at this point?
Sam Thomas - Chairman, President and CEO
I think I would say that it is our -- anticipated results are included in our guidance, number one. Number two, I don't expect significant upside opportunities nor do I expect significant surprises from those projects. We are winding them both down. I think we've got the anticipated results fairly well baked in.
Roger Read - Analyst
And when would those projects be off the income statement? I mean what is the anticipated completion dates?
Sam Thomas - Chairman, President and CEO
That is a tough one because there are small change orders and small finish up tasks to fully close them out. I anticipate that both will be largely done in the fourth quarter of 2007. There is some possibility of slight overhang into the first quarter of 2008. But I don't expect it to be material whatsoever.
Roger Read - Analyst
Okay. Second question, you mentioned -- this is the first time at least I've heard of it, the alliance with Energy World. Can you give us an idea of exactly what is involved there? I mean clearly significant award in the second quarter here. But I'm just wondering what does that lay out a particular possibility of a level of orders? Is pricing at all set in that? Maybe just put a little more meat on the bones for us there?
Sam Thomas - Chairman, President and CEO
It is really a preferred supplier cooperation agreement. We've done significant development work with Energy World for what they consider to be a platform for modular plants of relatively small size in the global LNG train sizing range. But they anticipate building multiple plants in those smaller scale sizes in Southeast Asia or Australia. So we look at it as a just a signal of a very positive relationship with a -- with Energy World who has quite an aggressive position and are very optimistic about the LNG market.
Roger Read - Analyst
Okay and then just one housekeeping question for me. Probably for you, Michael. The corporate costs on a quarterly basis going forward, should we look for something that is kind of $5 million to $6 million range backing out what we saw in the second quarter and kind of what we've seen in prior orders?
Michael Biehl - CFO
Yes, that would be an appropriate range.
Roger Read - Analyst
Okay, thank you gentlemen.
Operator
Michael Weisberg, ING.
Michael Weisberg - Analyst
Good morning. A couple things if I could. The slowdown in D&S orders, that is basically -- that is all attributable to the merger, is that right?
Sam Thomas - Chairman, President and CEO
It is -- well let me rephrase that. First, we've increased capacity significantly in Distribution & Storage both -- all three locations, the Czech Republic, China and the U.S. So part of the decrease in backlog is the fact that we are growing sales. Second item is, the BOC/Linde merger where we did see an impact in orders received and I commented that we would expect that to translate into some sales softness in the second half of 2007 as a result.
Michael Weisberg - Analyst
Okay. Do you -- have you seen any softening in China? Just give us a sense of what is happening in the China and Czech businesses?
Sam Thomas - Chairman, President and CEO
In China, the outlook is extremely positive. We're constrained only by our capacity to grow. In the Czech Republic, we've come off a period of very high order intake in the back half of 2006, early 2007, and there has been some moderation of very large tank orders particularly for LNG projects and what has been booked in the last three, four months. But it is still very healthy and most areas of the plant are indeed capacity constrained. So it is a very positive outlook.
Michael Weisberg - Analyst
Without putting any specific numbers on this, Sam, could you envision the Czech and China business being as much as half of the overall D&S business by next year?
Sam Thomas - Chairman, President and CEO
Let's see, conceivably, yes.
Michael Weisberg - Analyst
Great. Great. Could you give us a sense just roughly the gross margins on E&C which were 27%, how much of a drain are those two small contracts? Because it sounds like you're generating some positive gross margins although -- but a lot less than the corporate average? Where would gross margins be running if you didn't have -- if these contracts were off the books?
Michael Biehl - CFO
Michael, they would probably be for the quarter they would be up more in the -- closer to the 30% range.
Michael Weisberg - Analyst
Wow. So just projecting out, E&C margins would be running 30 without the two problem contracts?
Sam Thomas - Chairman, President and CEO
Right.
Michael Weisberg - Analyst
Great. Are you going to get any revenues from the E&W Energy World business in '07?
Sam Thomas - Chairman, President and CEO
A little bit but not much of an impact in '07.
Michael Weisberg - Analyst
Much more of an impact in '08?
Sam Thomas - Chairman, President and CEO
Yes, definitely more in '08 and into '09 even.
Michael Weisberg - Analyst
How do you think those -- what is your sense of gross margins on that contract relative to where your existing E&C margins are?
Sam Thomas - Chairman, President and CEO
Higher on an average basis.
Michael Weisberg - Analyst
So you'll have higher gross margins there?
Sam Thomas - Chairman, President and CEO
Yes.
Michael Weisberg - Analyst
Maybe two more things if I could. Is there the possibility that the E&W business could be measurably higher than just the four trains they ordered if you look down the road?
Sam Thomas - Chairman, President and CEO
It's possible. That's one of the reasons we entered into the alliance agreement that we do believe that there is possibly other projects coming forward.
But just to clarify, there is additional -- some additional possibility in the late 2008, 2009 timeframe from what we've announced and then significant in terms of their plans, they see orders in the future of several times what has been booked if their plans come to fruition.
Michael Weisberg - Analyst
Several times, oh great. This is sort of a new venture in the LNG business. Are there other people sort of looking at this? If you want to look out a couple years, could this be sort of a new niche or a new market within the overall LNG construction business where you're less dependent on big foreign governments which take a long time to do anything and more -- doing more smaller plants by independent companies? Is that something that could spread beyond this company?
Sam Thomas - Chairman, President and CEO
We believe so. There's a number of people studying these possibilities in both Indonesia, Western Australia, Norway and South America to name a few. There is also some view that these types of projects would be -- would pay off in Russia.
Michael Weisberg - Analyst
Really, that is great. Great job. Thanks a lot.
Operator
Garo Norian, BlackRock.
Garo Norian - Analyst
I wanted to ask if you guys -- do you know of any mix changes in any of the three segments that you would likely see second half versus kind of second quarter just to get a sense of what you know is in the backlog?
Sam Thomas - Chairman, President and CEO
Just as we have indicated, if you look at the BioMedical business, there is more strength in biological storage and there is in respiratory globally and particularly with respect to the U.S. market. In Distribution & Storage, we've already indicated that there will be some softness in the bulk tank market in comparison to the packaged gas market because of the bleed off of inventory following the Linde/BOC acquisition.
We continue to see very strong demand internationally both Czech Republic and China. Quite a bit of strength in our microbulk product range as being one of the leaders.
Within the E&C business, the mix shifted is generally with very strong sales for the Brazed Aluminum Heat Exchanger productline. In terms of demand, we see quite a bit of strength in the industrial gas markets as opposed to the hydrocarbon markets in the second half. And then in terms of E&C global mix as we reported previously, the strength is coming from China, Southeast Asia and the Middle East.
Garo Norian - Analyst
Great. And on the Distribution & Storage side, I mean you guys have kind of lived through a lot of consolidation and customer base over the last several years. Is kind of a six-month time period or six to nine months is that the typical that you've seen when kind of inventory type of adjustments are made by the customers?
Sam Thomas - Chairman, President and CEO
I don't know that we can say that it is a typical time but from our conversations with those customers, they are quite confident and bullish about the strength of their business and new installations so that we are back to talking about new projects for which they require additional tanks. So we expect that six-month period in terms of order intake is coming to an end and will be largely fed through by the end of the third quarter meaning -- saying that the sales hit to us will be largely accounted for in the second half of this year, perhaps a little bit into the first quarter of 2008.
Garo Norian - Analyst
Okay, great. And just the last question I have is tax rate expectations for this year and next year for you guys, what would best guess be?
Michael Biehl - CFO
It should be in the 34% range for this year and the expectation for next year, it should be very similar.
Garo Norian - Analyst
Okay, thanks very much.
Operator
Chris Agnew, Goldman Sachs.
Chris Agnew - Analyst
Thanks. Good morning. First question on CapEx. Can you outline how you're progressing with your strategic expansions? And therefore what the outlook is for CapEx for the full year? And maybe if you can talk to where you are spending that CapEx? Thanks.
Michael Biehl - CFO
Two places where we are spending the largest amount are both in China and in our Energy & Chemicals La Crosse, Wisconsin facility. Both of those are moving forward. We expect to have completed the expansions by the end of the third quarter. We should be somewhere for the year in the $25 million to $28 million for CapEx compared to the prior year. And that would include those expansions for both of those and again, those are the really the primary drivers of that CapEx this year.
Chris Agnew - Analyst
And then once you've completed toward the end of this year, what should we be thinking about in terms of ongoing CapEx?
Michael Biehl - CFO
Probably 15 to $20 million.
Chris Agnew - Analyst
Does that include further expansion plans, capacity expansion plans?
Michael Biehl - CFO
There is some potential there but probably be at the lower end of that range, the 15 to $20 million. It depends if some -- there's a few pieces of this expansion that may carry over. But right now I would expect it to be closer to the $15 million range going forward with about roughly $8 million of that being maintenance CapEx. So, yes, there is $7 million other types of projects in there on an ongoing basis.
Chris Agnew - Analyst
Okay, thanks. Second question is, I think on your first quarter conference call you talked about a proportion of fixed price contracts about 75% of your backlog. Can you update us as to where you are at the end of the second quarter? And also, what proportion of those have you the ability to put through price increases for commodity costs?
Sam Thomas - Chairman, President and CEO
In terms of the backlog with fix prices, the percentage which are fixed price would be nominally the same. Of that total, perhaps one-third to one-half has the capability of surcharges or reflecting change orders going into them. It's not a situation significantly different than we had at the end of the first quarter. Probably the most significant feature of the overall operating environment is that nickel prices appear to have peaked roughly two to three months ago and have moderated which certainly if it stays that way, which the forecasts are that nickel is going to stay significantly off that peak of this experience I think in June. But that takes significant pressure and risk away from us.
Chris Agnew - Analyst
Okay. Thanks. And then final question, do you have to hand what working capital usage was in the quarter? Thanks.
Michael Biehl - CFO
I'm sorry, would you repeat that, Chris.
Chris Agnew - Analyst
Do you actually have to hand what working capital usage was in the second quarter? Cash used?
Michael Biehl - CFO
Yes, we did, we talked about that.
Sam Thomas - Chairman, President and CEO
It was part of the release, was it not?
Michael Biehl - CFO
From operating activities which would include -- the working capital was roughly about $6 million of usage, working capital usage.
Chris Agnew - Analyst
Okay, thanks very much.
Operator
(OPERATOR INSTRUCTIONS) There are no further questions at this time.
Sam Thomas - Chairman, President and CEO
Okay, we'll end the call. Thank you very much everyone. Bye.
