Wahid Nawabi -- President and Chief Executive Officer
Thank you, Steve. And welcome to our second quarter fiscal Year 2019 earnings conference call.
On today's call, we will focus on three key messages. First, our team is successfully executing our plan as reflected in our strong second quarter and first half results. Second, continued strong backlog and visibility keep us on track to achieve our fiscal year 2019 objectives. And third, robust customer demand for our innovative solutions, coupled with our strategy, support our long-term value creation goals.
Today, I will review our second quarter fiscal year 2019 financial and operating performance, and then provide an overview of some notable developments during the quarter. Next, Teresa Covington, will provide a detailed review of second quarter and year-to-date financials. Then, I will discuss our goals for fiscal year 2019, including our revised guidance, which reflects our strong momentum. Teresa, Steve and I will then take your question.
We are executing our fiscal year 2019 plan and continue to deliver strong results. Second quarter revenue of $73 million increased by 11% year-over-year. Earnings per diluted share from continuing operations was $0.29. Funded backlog increased by 44% from $113 million to $164 million year-over-year. It is important to note that over the last four quarters, we have consistently generated high funded backlog levels. This strong funded backlog is helping us level load quarterly revenue and our operations.
Year-to-date, our performance reflects strong improvement over last year. Revenue of $151 million increased by 51% over fiscal year 2018, and earnings per diluted share from continuing operations of $1.14, including a $0.26 one-time litigation settlement is up $1 over the same period last year. This strong year-over-year improvement significantly enhances our visibility as Teresa will detail shortly.
Now let's review some notable developments from the quarter. Within the US Department of Defense market, we remain the leader in small UAS and our growing loitering missile systems business is disrupting the Tactical Missile Systems category. The recently released 2018 (ph) US National Defense Strategy defines a number of initiatives designed in part to enhance the lethality of US military forces. These initiatives includes several supported by AeroVironment solutions, namely expanding surveillance, investing in infantry firepower and increasing the production of critical ammunition.
AeroVironment unmanned solutions deliver greater situational awareness and lethality to frontline troops more affordably than many legacy ISR and weapon systems. We believe our solutions will serve an important role in providing US and allied forces winning capabilities and the future battle space through existing and next generation offerings.
We also believe our solutions deliver exceptional capabilities and value in both conventional and non-conventional threat environment. Examples of new US DoD procurement opportunities include the Army's Short Range Reconnaissance and Soldier Borne Sensor programs. Both of these programs represent initial adoption opportunities for our next generation small UAS. We are tracking them closely and look forward to updating you when we have news to share.
The fiscal year 2019 Defense Appropriations Bill was enacted in our second quarter, and demand for our solutions remained robust. Nearly $60 million was appropriated for our small UAS, made up of the Army's $46 million funding for Raven systems and the Air Force's $13.5 million for Puma system. And $110 million was appropriated for the Army and Marine Corps LMAMS requirement which specify AeroVironment as the supplier. This totals $170 million of appropriated funding for AeroVironment solutions. We look forward to negotiating and finalizing contract awards for these line items in the coming months.
Based on our winning track record, we continue to expand our leadership position in the small UAS category for defense requirement internationally with more than 45 allied customers.
Notable second quarter contract awards that reflect our strong international position are as follows: a $5.9 million NATO Support and Procurement Agency contract for Raven systems for the Portuguese Army, our first contract with Portugal; a $13 million US Air Force IDIQ contract to support Raven systems to multiple Caribbean nations; a $9 million Puma systems award for our Baltic nation; and a $3.2 million Puma systems award for an ally in the DoD's Indo-Pacific Command region.
We believe small UAS and TMS are in the early stages of market adoption. We envision a future in which unmanned systems deliver increasingly valuable capabilities across defense and commercial markets, and well beyond their contributions today. Achieving these broader and deeper penetration of unmanned systems requires continued innovation across hardware and software domains. It also involves the implementation of unmanned solutions and new integrated approaches in which they work together to deliver more significant benefits to our customers.
In October, we announced the teaming agreement with General Dynamics Land Systems that serves as a powerful example of this new integration approach. We are working with General Dynamics to integrate small UAS and Switchblade Tactical Missile Systems into armored combat vehicles for new upcoming US Army and Marine Corps acquisition programs, and for potential retrofit of existing vehicles. Essentially, we are establishing a new paradigm air power in which armored vehicle commanders would possess their own aerial capabilities for reconnaissance and precision strike while stationary or on the move.
Working together, our small UAS and Switchblade, for example, can deliver game changing situational awareness and precision strike capabilities directly to the commander of an unarmored vehicle. This represents a new channel for us to enable and protect the war fighter. It can also generate additional demand for our solutions through our other programs of record. This also represents an important new way to integrate our unmanned systems into other platforms to enhance our customers' battlefield capabilities across multiple domains. While development of this integrated solution is at a very early stage, we are confident in its superior ability to enable and protect the war fighter.
In our nascent commercial businesses, we remain focused on executing our design, development and demonstration program perhaps. We consider the ongoing announcements of new competing solutions emerging from multiple new players in this market as a recognition of the potential of this large global opportunity.
In Commercial Information Solutions, we continue to expand our reach into the large agriculture market. We continue to believe in the compelling value proposition of our unique solution. However, the overall market adoption rate is lower than most anticipated as we have previously communicated. We continue to seek strategic partners to help us capitalize on this potentially large long-term value creation opportunity.
Now, Teresa will review our second quarter financials. Teresa?
Teresa Covington -- Senior Vice President and Chief Financial Officer
Thank you, Wahid, and good afternoon, everyone.
AeroVironment's fiscal 2019 second quarter results are as follows. Revenue from continuing operations for the second quarter of fiscal 2019 was $73 million, an increase of $7.2 million or 11% from the second quarter of fiscal 2018 revenue of $65.8 million. The increase was due to an increase in service revenue of $8.5 million, partially offset by a decrease of product deliveries of $1.3 million.
The second quarter fiscal 2019 revenue by major product line/program is as follows: small UAS was $42.2 million, TMS was $15 million, HAPS was $12.8 million, and other was $2.9 million.
Gross margin from continuing operations for the second quarter fiscal 2019 was $28.4 million or 39% of revenue compared to $30.1 million or 46% of revenue for the second quarter of fiscal 2018. The decrease in gross margin was primarily due to a decrease in product sales margin of $2.7 million, partially offset by an increase in service margins of $1 million.
Gross margin, as a percentage of revenue, decreased from 46% to 39% due to a higher percentage of service revenue in the second quarter as well as lower gross margins in both product sales and service revenue due to mix.
Looking at the rest of the income statement, SG&A expense from continuing operations for the second quarter of fiscal 2019 was $13.6 million or 19% of revenue compared to SG&A expense of $12.8 million or 19% of revenue for the second quarter of fiscal 2018. R&D expense from continuing operations for the second quarter of fiscal 2019 was $8.1 million or 11% of revenue compared to R&D expense of $6.8 million or 10% of revenue for the second quarter of fiscal 2018.
Income from continuing operations for the second quarter of fiscal 2019 was $6.6 million or 9% of revenue compared to a $10.5 million or 16% of revenue for the second quarter of fiscal 2018. The decrease in income from operations was primarily due to a decrease in gross margin of $1.7 million, an increase in R&D expense of $1.3 million and an increase in SG&A expense of $0.9 million.
Net other income for the second quarter of fiscal 2019 was $2.4 million compared to net other income of $0.4 million for the second quarter of fiscal 2018. The increase in net other income was due to income from the transition services agreement with Webasto Charging Systems and higher interest income on our investment.
The effective income tax rate from continuing operations was 13.5% for the second quarter of fiscal 2019, as compared to an effective income tax rate of 30.8% for the second quarter of fiscal 2018. The effective tax rate for the second quarter of fiscal 2019 included a discrete excess tax benefit of $0.4 million, resulting from the vesting of restricted stock awards and exercises of stock option.
Equity method investment activity, net of tax, for the second quarter of fiscal 2019 was a loss of $0.8 million or $0.03 per diluted share compared to no equity method investment activity, net of tax for the second quarter of fiscal 2018.
Net income from continuing operations attributable to AeroVironment for the second quarter of fiscal 2019 was $7 million or $0.29 per diluted share compared to net income from continuing operations attributable to AeroVironment of $7.8 million or $0.32 per diluted share for the second quarter of fiscal 2018.
The company completed the sale of the EES business through Webasto Charging Systems in the first quarter of fiscal 2019. The company has not received the additional holdback cash consideration of $6.5 million, which the company is entitled to receive upon tendering consents to assignment of two remaining customer contracts to Webasto. The company's satisfaction of the requirements for the payment of the holdback is currently under dispute.
Loss from discontinued operations, net of tax, for the second quarter of fiscal 2019 was $1 million or $0.04 loss per diluted share compared to a loss from discontinued operations, net of tax of $33,000 for the second quarter of fiscal 2018.
Now, moving through our first half fiscal 2019 results. Revenue for the first half of fiscal 2019 was $151 million, an increase of $50.8 million as compared to $100.2 million for the six months ended October 27, 2018. The increase in revenue was due to an increase in product deliveries of $35.1 million and an increase in contract service revenue of $15.7 million.
The first half of fiscal 2019 revenue by major product line/program is as follows: small UAS was $83.4 million, TMS was $37.8 billion, HAPS was $24.4 million and other was $5.4 million.
Gross margin for the first half of fiscal 2019 was $61 million or 40% as compared to $38.8 million from 39% for the first half of fiscal 2018. The increase was due to an increase in product margins of $20 million, and an increase in service margins of $2.2 million. Gross margin as a percentage of revenue increased from 39% to 40% due primarily to higher gross margin and product sales, partially offset by lower gross margins in service revenue.
SG&A expense for the first half of fiscal 2019 was $25.6 million or 17% of revenue compared to SG&A expense of $24.1 million or 24% of revenue for the first half of fiscal 2018.
R&D expense for the first half of fiscal 2019 was $14.5 million or 10% of revenue compared to R&D expense of $12.4 million or 12% of revenue for the first half of fiscal 2018.
Income from continuing operations for the first half of fiscal 2019 was $20.8 million or 14% of revenue compared to $2.4 million or 2% of revenue for the first half of fiscal 2018. The increase in income from operations was primarily due to an increase in gross margins of $22.2 million, partially offset by an increase in R&D expense of $2.2 million and an increase in SG&A expense of $1.6 million.
Net other income for the first half of fiscal 2019 was $11.7 million compared to the prior year net other income of $0.9 million. The net other income increase was primarily due to a litigation settlement income earned under a transition services agreement with Webasto Charging Systems and an increase in interest income resulting from higher short-term interest rates in fiscal 2019.
The effective income tax rate from continuing operations was 11.6% for the first half of fiscal 2019 as compared to an effective income tax rate of 4.2% for the first half of fiscal 2018. The increase in effective income tax rate was due to higher income before taxes, partially offset by reduced federal statutory rate from the Tax Cut and Jobs Act.
Equity method investment activity, net of tax, for the first half of fiscal 2019 with a loss of $1.4 million or $0.06 per diluted share compared to no equity method investment activity, net of tax for the first half of fiscal 2018.
Net income from continuing operations attributable to AeroVironment for the first half of fiscal 2019 was $27.4 million or $1.14 per diluted share compared to $3.4 million or $0.14 per diluted share for the first half of fiscal 2018.
Our funded backlog as of October 27, 2018 was $163.9 million, an increase of $50.3 million or 44% from the second quarter of fiscal 2018 and an increase of $6.8 million or 4% from the first quarter of fiscal 2019.
Turning to our balance sheet, cash, cash equivalents and investments at the end of the second quarter fiscal 2019 totaled $320.3 million, an increase of $22.5 million from the end of fiscal 2018 cash, cash equivalents and investments of $297.8 million.
Net accounts receivable, including unbilled receivables and retention at the end of the second quarter of fiscal 2019 totaled $80.3 million. The unbilled receivables and retention balance of $45.7 million inclusive of $7.8 million related party amounts. The unbilled receivables and retention balances arise due to timing differences between revenue recognition and billing. All revenue from Tactical Missile Systems contract is now recognized over time, which generally accelerates the timing of when revenues recognize and results in a increased unbilled receivables.
Total days sales outstanding from continuing operations for the second quarter fiscal year 2019 was approximately 95 days compared to 48 days for the fourth quarter fiscal year 2018. Net inventory at the end of the second quarter fiscal year 2019 was $46.1 million compared to $37.4 million at the end of the fourth quarter fiscal year 2018.
Days in inventory outstanding for the second quarter fiscal year 2019 was approximately 89 days compared to 79 days for the fourth quarter fiscal year 2018. Accounts payable at the end of the second quarter fiscal year 2019 was $14.1 million compared to $21.3 million at the end of the fourth quarter fiscal year 2018. Total days payable outstanding for the second quarter fiscal year 2019 was approximately 27 days compared to 24 days for the fourth quarter of fiscal year 2018.
Turning to capital expenditures, in the second quarter fiscal year 2019, we invested approximately $2.7 million in property improvements and capital equipment and recognized $1.8 million of depreciation and amortization expense.
Now an update to our fiscal 2019 visibility. As of today, we have year-to-date revenue in fiscal 2019, a $151 million second quarter ending backlog that we expect to execute in fiscal 2019 of $127 million. Q3 quarter-to-date bookings that we anticipate to execute in fiscal 2019 of $0.3 million. Unfunded backlog from incrementally funding contracts that we anticipate to recognize revenue during the balance of the year of $17 million. This adds up to $296 million or 97% at the midpoint of revenue guidance. We anticipate a full year effective tax rate for continuing operation in the range of 12% to 14%.
Now, I would like to turn things back to Wahid to discuss AV's expectations for fiscal year 2019.
Wahid Nawabi -- President and Chief Executive Officer
Thanks, Teresa. We're executing our plan effectively and enhancing our position for long-term value creation. Customer demand for our solutions remain robust, supported by strong DoD appropriations for those solutions. With strong and steady performance so far this year, we now have 97% visibility to the midpoint of our revised revenue guidance range as Teresa described. This represents historically high visibility for us at this point in the fiscal year.
The term visibility in this context refers to converting funded backlog and unfunded commitments into revenue in the current fiscal year. So while visibility tells us much about the front-end of the business, there remains timing and execution risks to fulfilling those orders on the back end, and achieving our full year guidance. With respect to our earnings, year-to-date, we have also generated earnings per share from continuing operations of $1.14 which places us within our EPS guidance range already.
While this as context -- with this as context, we are narrowing our revenue guidance within the upper portion of our range to between $300 million and $310 million, and we are raising and narrowing our earnings per diluted share from continuing operations guidance range to between $1.30 and $1.50.
As we indicated earlier, this fiscal year, we expect first half revenue to be similar to second half revenue and fairly evenly distributed across all four quarters. This represents a significant change from prior years when historically our fourth quarter produced the largest quarterly revenue. We also expect lower profitability in the second half, mainly due to higher plant operating expenses and a shift in our revenue mix with higher services sales compared to product sales.
We continue to expect research and development investments to total 10% to 11% of full year revenue. These factors drive the revised guidance which I just outlined. We are confident in our ability to extend our record of delivering on our objectives and achieving these revised targets.
In summary, to reiterate our main points for today's call. First, our team is successfully executing our plan as reflected in our strong first half results; second, continued strong backlog and visibility keep us on track to achieve our fiscal year 2019 objectives; and third, robust customer demand for innovative solutions coupled with our strategy, support our long-term value creation goals.
Thank you to AeroVironment team members for your relentless drive to serve our customers and stockholders. Thank you to our customers who placed their trust in AeroVironment to support their critical missions. And thank you to our stockholders for recognizing the value creation potential of our people and our company.
Theresa, Steve and I will now take your questions.
Questions and Answers:
Operator
Thank you. We will now begin the question-and-answer session. (Operator Instructions) And our first question comes from Ken Herbert from Canaccord. Please go ahead. Your line is open.
Ken Herbert -- Canaccord Genuity Inc. -- Analyst
Hi. Good afternoon.
Wahid Nawabi -- President and Chief Executive Officer
Good afternoon, Ken.
Ken Herbert -- Canaccord Genuity Inc. -- Analyst
Hey, Wahid, I first wanted to ask about the LMAMS, $110 million in the fiscal 2019 budget. I'm curious, have you seen any of that -- I mean, is that any of that yet under contract? I know you've talked about timing and we're very early in the fiscal year, but can you just update us on where we are in the contract? Have you seen any of that yet? And then maybe how we should expect or how much of that potential in the budget do you see in your fiscal 2019 just considering the timing?
Wahid Nawabi -- President and Chief Executive Officer
Sure. So Ken, the $110 million appropriated and authorized budget dollar amounts that are in the government fiscal year 2019, which I mentioned earlier, is not under contract with us yet. We are already working on that. We're aware of it, as I mentioned. And we continue to work toward the definitization and finalization of that contract with the customer. And once we do that we will obviously update you as we go forward. At this time, we're in that position.
Ken Herbert -- Canaccord Genuity Inc. -- Analyst
Okay. So, is it possible, Wahid, even just give an estimate of maybe how much of that is factored into the guidance this year versus how much maybe falls into your fiscal 2020?
Wahid Nawabi -- President and Chief Executive Officer
Yeah. So, unfortunately, because we're still in contract negotiations and definitization process. I'm not in a position to be able to comment on that specifically. Historically speaking, you know it always has taken a certain amount of time for us to negotiate the contract, definitize it, finalize it, and then we have to produce the product and then obviously test them and then get approval from the customer to be able to deliver them. All of that activity is obviously planned and under way, but still to be done.
Operator
And our next question comes from Jonathan Ladewig from Stifel. Please go ahead. Your line is open.
Jonathan Ladewig -- Stifel, Nicolaus & Company, Inc. -- Analyst
Hey, guys. Thanks for taking my call. I was hoping you guys could first start off with updating us on your capital allocation plans these days? And kind of give us some color on what the latest thoughts are around HAPSMobile?
Wahid Nawabi -- President and Chief Executive Officer
Yes. Hi there, Jon. So, in terms of capital allocation, we currently in our financial outlook that we provided assume a 5% ownership in the joint venture with HAPS, you mentioned specifically HAPS. But per contract terms, we have the ability and the option to increase our joint venture ownership up to 19% during this step to contract with certain terms and conditions that are within the contract. And we have not to date executed that or implemented that. So, as we progress through this process, we will keep you updated.
And so, as I've said before, the initial joint venture was $100 million joint venture, which we contributed up to 5% of that for the ownership piece. That's one piece, and then obviously besides that we have ordinary Capital consumption and investments in various parts of our business, such as tooling and fixtures and operations that we do and Teresa usually provides an update on that, and that's the primary status of our capital expenditures year-to-date for this year.
Jonathan Ladewig -- Stifel, Nicolaus & Company, Inc. -- Analyst
Hi. Thank you. Two other ones here just real quick. Can you kind of update us on the impact, the change in the export laws have had on your sales to date? You talked about a bunch of the international sales, but has it fundamentally changed since the White House made that transition for allowing for additional exports? And then can you kind of give us some color on the breakout for sales between TMS international small and HAPS?
Wahid Nawabi -- President and Chief Executive Officer
Sure. So, in terms of export licensing, Jon, we really haven't noticed a significant or meaningful change in the way that the export license are being processed or authorized. Having said that, historically speaking, we have a very strong track record of obtaining and complying with all the requirements with the State Department for obtaining those licenses. And as you heard from my comments, we're up to over 45 allied countries now in terms of international customers for our small UAS products and solutions. And it's a growing list, and I mentioned the number of new awards that we have achieved in the second quarter earlier in my remarks.
In terms of the breakdown of the revenue, Teresa can actually help you through with those numbers now.
Teresa Covington -- Senior Vice President and Chief Financial Officer
Hi, John. As I had talked about in my prepared remarks, for the first six months of fiscal 2019, small UAS was $83.4 million, Tactical Missile Systems was $37.8 million, HAPS is $24.4, other was $5.4. For the first half of fiscal 2018, small UAS was $67.1 million, TMS was $18.9 million, HAPS was $9.6 million, other was $4.5 million.
For the first six months of fiscal 2019, our domestic sales were $82.1 million, international sales were $68.9 million, and for the six months of fiscal 2018, domestic sales were $60.7 million, international sales were $39.4 million.
Operator
And our next question comes from Ken Herbert from Canaccord. Your line is open.
Ken Herbert -- Canaccord Genuity Inc. -- Analyst
Yeah, hi, good afternoon. I just wanted to follow up --
Wahid Nawabi -- President and Chief Executive Officer
Hi, Ken.
Ken Herbert -- Canaccord Genuity Inc. -- Analyst
Yeah. Hi, Wahid. You'd mentioned part of the headwind in the second half of the year at least from a margin or maybe gross margin standpoint was going to be a step up in some corporate expenses. I'm just wondering if you could maybe just provide the magnitude of that? And is that something we should think about as sort of one-time as we think about sort of moving out of the second half of 2019?
Wahid Nawabi -- President and Chief Executive Officer
Sure. Ken, so I can -- generally speaking, as I mentioned in my remarks, our second half profitability profile looks obviously slightly lower than our first half to achieve the results that I provided in my guidance, the revised guidance. And there's two primarily reasons for that. First is our revenue mix. And in the revenue mix, given any quarter because our revenue is made up of large sums of projects and solution delivery, the profile of those contracts and profitability of those contracts could vary, such as services contract versus product contracts, and cost-plus contracts versus firm fixed price contracts, et cetera, et cetera. So that's one category of impact for the second half.
The second one is, we also expect and plan higher operating expenditures, both on the R&D side as well as on the SG&A side. And those two factors are the primary factors affecting the profitability for the second half. And yes, to your second question we -- this is really what I referred to based on the time frame that you look at this kind of a number. In other words, I don't foresee this as a systemic issue, I see this as a unique to the second half of the year as we are today. And it may change in different directions in the future, Ken.
Ken Herbert -- Canaccord Genuity Inc. -- Analyst
Okay. That's very helpful. And if I could just one final follow-up. You'd also mentioned that the $6.5 million I believe was expected payment in this quarter from the purchaser of the EES business was in dispute. Is that -- do you think there's risk to that number or is that just sort of timing, I mean, how do we think about that potential cash payment for the final transaction?
Wahid Nawabi -- President and Chief Executive Officer
Sure, Ken. So, yes, as Teresa mentioned, that is in dispute right now with us within the purchaser of the assets. And as you know in different transactions, there is always issues related to deep contract terms and how we negotiate those things. We are obviously working with them on that. We are still currently providing transitional support services to them in multiple fashions. However, there is a risk to that and we're working through that, and as we have more updates throughout the next several months and quarters, we will update and let you know.
Operator
(Operator Instructions) And our next question comes from Peter Arment from Baird. Please go ahead. Your line is open.
Peter Arment -- Robert W. Baird & Co. -- Analyst
Yes. Good afternoon, Wahid.
Wahid Nawabi -- President and Chief Executive Officer
Hi, Peter. Good afternoon.
Peter Arment -- Robert W. Baird & Co. -- Analyst
Hey. So, question I guess is around, you've had 45 countries, I guess. The international mix continues to grow. Can you talk us a little bit about are all those countries come with service contracts? Is that potentially a longer tail for the revenue stream as this grows with the international mix? And then just as a follow-up, unrelated, but when do you expect to deliver the two prototype aircraft for the HAPS? Thanks.
Wahid Nawabi -- President and Chief Executive Officer
Sure. Peter, so in terms of our international market and customer adoption, we're now up to over 45 countries. The types of contracts that we have with those customers all vary, but overwhelming the majority, yes, they have both initial hardware sales, in addition to that we also have logistics support services and training services to help our customers train and using our products and then also maintaining and operating our products and solutions. So that is definitely true. And secondly in general, when we acquire new international or domestic customer, there is always historically, and in the future as well continues to be a long tail in terms of sustainment and maintenance and upgrades.
And in general, the international markets, I have said this before that we still believe it is about five plus years behind the adoption curve of our US domestic customers in terms of maturity and adoption. So, as I said before, we continue to believe that the international market for our small UAS is strong and remains robust, and we're working to not only grow the number of international customers, but also our share of their spend and our solution portfolio within those customers can grow as a family of solutions for those customers as we go forward.
In terms of HAPS, we have not specified the specific timing of the deliveries of the three airplanes, while we have said before, we continue to say that, we are right now focused on executing our step to design, development and demonstration program which includes the delivery of two airplanes in that process. And as we have updates, we will obviously keep you notified.
