Thanks, Michael. Good morning, and thanks to everyone on the call. We are pleased with the strong first quarter with growth across all 3 business segments and profit results ahead of our expectations. The general trends in our business remains solid with revenue growth in line with our expectations in Life Science and Isomedics, including contribution from the acquisition of Biotest.
Our healthcare segment excluding SYSTEM 1 and SYSTEM 1E, also delivered good growth, in particular from newer products, and we anticipate that will continue. As you know, shipments of S20 sterilant and support of SYSTEM 1 units in the U.S. ends today. It has been a long, expensive and challenging road, but I'm proud of the way our people have worked to support our customers and assist them in making this transition.
In many ways, we are glad to put this chapter behind us. As you might imagine given the timing of our transition deadline, we shipped over 700 SYSTEM 1E units in the quarter. Through the end of June, we have now shipped about 6,000 SYSTEM 1E units since the introduction of the product a couple of years ago, which is in line with our expectations.
We believe that we have shipped the majority of units that will be sold this fiscal year in the U.S. and we have nearly achieved our United States SYSTEM 1E unit volume projection for the year. Even though that is good news, it does mean that we have somewhat tougher year-over-year comparisons the next few quarters, as we were actively shipping units all last year.
We are seeing S20 sterilant continue the expected decline in the United States, which will be flatlining after today. But the new S40 Sterilant has ramped up from quarter-to-quarter, so the net shipments of S20 and S40 is in line with our forecast. As you know, we have given a range of ongoing sterilant sales in the U.S. versus our sales before the transition started, at about 30% to 40% of our historic volume.
It appears that our going forward sterilant revenue will be in the midpoint of that range. We have completed our software update for SYSTEM 1E in the field and as anticipated, has seen a significant decline in the number of service requests due to unit downtime. Consequently, our SYSTEM 1E field costs are tracking to our forecast. As Mike indicated, the end result of all these activities is a nice reduction in our expenses compared with the fourth quarter levels and we are on our plan to reduce that cost even further.
We have officially launched our support tester for S1E and we will begin shipping during the second quarter. And our customers have also widely adopted the use of our chemical indicator. These optional accessory products do not translate into big revenue dollars, but they are important to many of our customers and thus important to us.
Outside of the SYSTEM 1 franchise, healthcare had a good quarter and specifically for several of our newer products, [indiscernible] cleaning chemistries, the new IQ 3000 integrated OR, our value line of LED lighting, the 4085 surgical tables and VPRO MAX. We have recently received key endorsements for VPRO MAX from industry partners including Olympus for their endoscopes.
As you all know, we recently announced a proposed acquisition of U.S. Endoscopy, which should close this quarter. Even though we will only have a partial year impact from the business, it is sizable enough for us to update our revenue outlook for FY '13. We now anticipate total company revenue growth to be in the range of 3% to 4% compared with our prior expectations of flat revenues for the year, largely a result of the acquisition.
Similarly, healthcare segment revenue is expected to grow low single-digits compared with previous expectations of a decline in revenue of low single-digits. The revenue outlook for Life Science and Isomedix are unchanged.
As Mike has already mentioned, going forward, we will provide you as GAAP earnings per share as well as adjusted earnings per share for the full fiscal year. On a U.S. GAAP basis, we are maintaining our outlook for earnings per diluted share in the range of $2 to $2.20 for fiscal 2013, which now includes approximately $0.05 of dilution from the U.S. Endoscopy acquisition on a GAAP basis.
Adjusted earnings per diluted share are anticipated to be in the range of $2.15 to $2.35 including accretion of approximately $0.05 per share from the acquisition of U.S. Endoscopy. This compares with adjusted earnings per share last year of $2.22 on the same basis. Give our success in Q1, we now anticipate more like a 45-55, first half-second half split in EPS.
For the full fiscal 2013, free cash flow is now anticipated to be approximately $130 million, excluding SYSTEM 1 Rebate Program and class action settlements or $90 million including these items. We have increased our estimate of free cash flow by $10 million to reflect our first quarter performance. We are confident in our free cash flow generation and continue to believe that we have capacity to fund additional investments in order to grow the business. We expect longer-term annual free cash flow to be in the $125 million to $150 million.
Our capital allocation strategy is unchanged. We continue to increase our dividend over time. In fact, our board just approved our seventh consecutive double-digit percentage increase in the dividend today. We will now pay $0.19 per share per quarter, which is about 2.5% yield based on our recent stock trading range.
And we are continuing our investments in our business including new product development, investment and capacity expansion, and our in-sourcing projects. By manufacturing more of our critical components, we believe we will improve quality, provide enhanced service to our customers and lower our costs. We also plan to invest in adjacent businesses that we find appealing through acquisition.
We have not repurchased stock so far this fiscal year as our existing 10b5-1 plan had expired at the end of fiscal '12. And we wanted to avoid any appearance of impropriety since we had inside knowledge regarding the U.S. Endoscopy acquisition.
However, we have approximately $118 million remaining on our existing authorization, and you should not be surprised if we're back in the market this year. We firmly believe that the results of all our efforts will continue to create value for our customers, our people and our shareholders in the years to come.
With that, I'll turn the call back over to Julie to begin the Q&A.
