Operator

Good day, everyone, and welcome to this Microchip Technologies Second Quarter and Fiscal Year 2019 Financial Results Conference. (Operator Instructions)

At this time, for opening remarks and introductions, I'd like to turn the -- over to Mr. Eric Bjornholt. Please go ahead, sir.

J. Eric Bjornholt -- Vice President and Chief Financial Officer

Thank you, and good afternoon, everyone. During the course of this conference call, we will be making projections and other forward-looking statements regarding future events or the future financial performance of the Company. We wish to caution you that such statements are predictions and that actual events or results may differ materially. We refer you to our press releases of today, as well as our recent filings with the SEC that identify important risk factors that may impact Microchip's business and results of operations.

In attendance with me today are Steve Sanghi, Microchip's Chairman and CEO, and Ganesh Moorthy, Microchip's President and COO. I will comment on our second quarter fiscal year 2019 financial performance and Steve and Ganesh will then give their comments on the results, discuss the current business environment as well as our guidance, and provide an update on our integration activities associated with the Microsemi acquisition. We will then be available to respond to specific investor and analyst questions.

I want to remind investors that during the quarter ending June 30, 2018, we adopted a new GAAP revenue recognition standard, which requires revenue to be recognized at the time products are sold to distributors versus our historical revenue recognition policy, where revenue on such transactions were deferred until the product was sold by our distributors to an end customer. We are not able to provide guidance on a GAAP basis, as we are not able to predict whether inventory at our distributors will increase or decrease in relation to end market demand and this is not how we manage our business.

As evidence of this uncertainty, in recent years, we have seen net inventory at our distributors increase or decrease by a significant amount in a single quarter. Our non-GAAP revenue is based on true end market demand in which we measure the revenue based on when the product is sold by our distributors to an end customer. We will continue to manage our business and distributor relationships based on creating and fulfilling end market demand. All of Microchip's bonus programs will continue to work based on the amount of revenue earned from fulfilling market demand. Therefore, along with GAAP results based on sell-in, we will also report our non-GAAP results based on sell-through revenue recognition.

I will now go through some of the operating results, including net sales, gross margin, and operating expenses. I will be referring to these results on a non-GAAP basis, using revenue based on end market demand, and expenses prior to the effects of our acquisition activities and share-based compensation.

Non-GAAP net sales in the September quarter were $1.513 billion, just above the midpoint of our guidance and up 24.4% sequentially from net sales of $1.217 billion in the immediately preceding quarter. We have posted a summary of our revenue by product line and geography on our website for your reference.

On a non-GAAP basis, gross margins were 61.7%, operating expenses were 23.4% of sales, and operating income was a record $579.3 million and 38.3% of sales. Non-GAAP net income was a record $454.6 million. Non-GAAP earnings per diluted share was a record $1.81, which was $0.07 above the midpoint of our guidance of $1.74.

On a GAAP basis, net sales in the September quarter were $1.433 billion. GAAP revenue was impacted by a significant reduction in the Microsemi distribution channel during the quarter, resulting in Microsemi distributor months of inventory being down to 2.6 months. We believe that the current levels, the distributors are holding the amount of inventory needed to support end market demand and that the inventory levels are in line with the levels maintained by our distributors for our historical business.

GAAP gross margins were 48.1% and include the impact of $3.9 million of share-based compensation, $184.4 million of acquisition related and acquired inventory valuation and other costs, and $56.1 million impact from changes in distributor inventory levels. Total operating expenses were $586.6 million and include acquisition intangible amortization of $169.9 million, special charges of $18.2 million, $6.6 million of acquisition related and other costs and share-based compensation of $37.5 million. The GAAP net income was $96.3 million or $0.38 per diluted share and includes one-time tax benefits of $115.6 million related to a variety of matters, including tax reserve releases due to audit settlements and statute of limitations expiring, tax reform and transition tax refinement and intercompany restructuring of intellectual property.

The non-GAAP cash tax rate was 3.5% in the September quarter and we expect a similar rate for all of fiscal 2019. We expect our non-GAAP cash tax rate for fiscal '20 and fiscal '21 to be 5% or less. Exclusive of the transition tax any potential tax associated with restructuring the Microsemi operations into the Microchip global structure and any tax audit settlements related to taxes accrued in prior fiscal years.

We have many tax attributes and net operating losses, tax credits and interest deductions that will keep our cash tax payments low, the transition tax for the combined Microchip, Microsemi Group is expected to be about $364 million was recorded last fiscal year and will be paid over eight years. We have posted a schedule of our projected transition tax payments on the Investor Relations page of our website. For GAAP purposes, we had a significant tax benefit in the quarter for the variety of reasons I discussed earlier.

Moving onto the balance sheet, our inventory balance at September 30, 2018 was $836.7 million, including a $120.1 million of inventory mark-up from Microsemi required for GAAP purchase accounting. Excluding the inventory mark-up, we had a 117 days of inventory at the end of September quarter, which was down two days from the prior quarter levels. Inventory at our distributors in the September quarter were 37 days compared to 40 days at the end of June. As indicated earlier, we believe that our distributors are holding an appropriate level of inventory to support end market demand.

The cash flow from operating activities was a record $487.6 million in the September quarter. As of September 30, the consolidated cash and total investment position was $464.2 million. We paid down $501 million of total debt in the September quarter. And the net debt on the balance sheet reduced by $315.5 million. At September 30, our debt outstanding includes $3.1 billion of borrowings under our line of credit, $2.733 billion of Term Loan B, $2 billion in high-grade bonds and $4.481 billion of convertible debt.

Our net debt to EBITDA, excluding our very long-dated convertible debt that matures in 2037 and is more equity like in nature, was 4.9 at September 30, 2018. Our leverage is higher than we originally projected, primarily due to lower EBITDA from the Microsemi business, driven by needing to correct distribution inventory levels through lower shipment activity in the month of June, as well as in the September 2018 quarter. As indicated earlier, we believe the distribution inventory correction for Microsemi is essentially complete.

We are committed to using substantially all of our excess cash generation beyond our dividend payment to reduce our debt levels and we expect our debt levels to reduce significantly over the next several years. Our net leverage metrics are based on 12 month trailing EBITDA, which will continue to provide some headwinds due to the significant distribution inventory reductions, which caused our shipment activity to be significantly less than end market demand for the past two quarters, as well as our guidance for the December 2018 quarter.

Capital expenditures were $72 million in the September 2018 quarter, we expect about $50 million in capital spending in the December quarter and overall capital expenditures for fiscal year 2019 to be about $230 million to $250 million. We continue to add capital to support the growth of our production capabilities for our fast growing new products and technologies and to bring in-house more of the assembly and test operations that are currently outsourced. These capital investments will bring some gross margin improvement to our business, particularly for the Atmel and Microsemi manufacturing activities that we are bringing into our own factories. Depreciation expense in the September quarter was $47.2 million.

I will now turn it over to Ganesh to give his comments on the performance of the business in the September quarter and provide an update on some of the Microsemi integration activities. Ganesh?

Ganesh Moorthy -- President & Chief Operating Officer

Thank you, Eric, and good afternoon, everyone. As I review our product line performance, please bear in mind that the September quarter has a full quarter of contribution from Microsemi, while the June quarter only had a month of contribution from Microsemi. This along with the fact that Microsemi revenue only maps into four of the six product line reporting categories we have, while in some cases distort the quarter-over-quarter comparisons of revenue by product line.

Taking a closer look at microcontrollers, our microcontroller business was sequentially up 12.6% as compared to the June quarter. This benefited from a full quarter of Microsemi contribution in September as compared to a partial quarter for June. Our September quarter microcontroller revenue annualizes at almost $3.3 billion, putting us within striking distance in the next few years of the two industry players who are ahead of us in the 2017 microcontroller rankings. Our microcontroller portfolio continues to expand with several new product introductions, our roadmaps remain strong and design-in funnel is robust. We see all these as positive indicators for future growth. We believe we have the new product momentum and customer engagement to continue to gain even more share in the future.

Now moving to analog, our analog business was sequentially up 33.6%, as compared to the June quarter. This too benefited from a full quarter of Microsemi contribution in September as compared to a partial quarter for June. Our September quarter analog revenue annualizes at over $1.75 billion firmly in the top 10 of analog semiconductor players. With Microchip 2.0 and our total system solutions approach, we expect to continue to grow and gain further analog market share.

Next up is our FPGA business, which came to Microchip through the Microsemi acquisition. Our FPGA revenue hit an all time record even after going back through the Microsemi and Actel history. Our low power mid range PolarFire family continues to garner strong market acceptance with revenue more than doubling sequentially as compared to the end-market consumption in the full June quarter. Despite being a new product category for Microchip, we are optimistic about the prospects for the FPGA product line based on the highly defensible markets and applications they are designed into, as well as the intense design win focus and broad-based market application and customer focus requiring. These requirements are very similar to Microchip's microcontroller business requirements. And therefore, we expect the FPGA product line will very nicely leverage our capabilities.

Moving next to our licensing business, this business was sequentially up 40.3% as compared to the June quarter. We achieved an all-time record for our royalty revenue. Additionally, our results also benefited from the sale of a patent license for a specific set of patents that can be used in a noncompetitive fields of play. We did anticipate this patent license to close in the September quarter and included in our guidance. We continue to retain indefinite rights for these patents for the fields of players that are of interest to us. Even without the patent license sale, the September quarter licensing business revenue was sequentially up from June.

Let me share some background as to our thinking in regards to patent licensing. We have inherited a substantial patent portfolio from the companies we acquired over the last 10 years. Several quarters ago, based on licensing request we were receiving, our licensing business unit embarked on a strategy to monetize certain patents, which have value to players noncompetitive fields of play. In all cases, we retain rights to use these patents in our products as well. The first results from this monetizing effort is what we saw in the September quarter results. There is a second such patent license sale for a specific set of patents, which is in the advanced stages of negotiation; and is included in our guidance for the December quarter. Investors should expect that the revenue contribution in the future from this effort will be a little lumpy from quarter-to-quarter.

Our memory business was sequentially down 3.8% in the September quarter, as compared to the June quarter. And finally, our MMO, which stands for multi-market and other business was up 90.7% sequentially as we had a full quarter of Microsemi contribution in the September quarter, as compared to just a month in the June quarter. On a combined company basis, which has a full quarter of Microchip and Microsemi, our second quarter fiscal of 2019, non-GAAP end market demand revenue of $1.51 billion was split across the six product lines we report as follows. Microcontrollers were 54.2%, analog was 29%, FPGA was 6%, memory was 3.1%, licensing was 2.5% and MMO was 5.2%. We expect this will be the approximate forward going revenue percentages by product line and that quarter-to-quarter changes from here onwards will be relatively small.

Now an update on the Microsemi integration progress. The business unit integration continues to progress well. We are restructuring underperforming businesses, while implementing the strengths and best practices from both companies to drive improvements across the board. The key Microsemi business unit leaders, we retained continue to run their businesses and are adapting to the Microchip culture and business expectations. New product development and design win momentum are continuing to happen as planned.

The sales integration is also progressing well. We have converted the Microsemi sales team to a Microchip's style non-commissioned sales approach. Teams from Classic Microchip and Microsemi are working collaboratively as one team to drive new opportunities and pursue product cross-selling opportunities. Our internal reference designs are increasingly taking advantage of our combined total system solutions approach. A comprehensive analysis of our new channels and channel partners from the Microsemi acquisition was completed and we are making the adjustments required for an effective combined company approach.

The operations integration work is an enormously complex undertaking, as little to no integration of prior Microsemi acquisitions have taken place. Because of the size of the business and the absence of ERP integration by Microsemi, the business system and operational integration will be done in phases. The first phase for one of the business units went live on November 1 successfully. Further phases have been planned with the quarterly cadence of go live events for many quarters.

We expect the overall operational integration will take about two more years to complete. From a factory standpoint, the initial plans for insourcing some from Microsemi was outsourcing have been completed and prioritize actions to execute these plans have commenced. In the G&A functions, we eliminated some more of the support organizational redundancies and more will happen after we get further along with our business system and operational integration plan.

Let me now pass it to Steve for some comments about our business and our guidance going forward. Steve?

Steve Sanghi -- Chief Executive Officer

Thank you, Ganesh, and good afternoon, everyone. Today, I would like to first reflect on the results of the fiscal second quarter of 2019. I will then provide updates on our progress at Microsemi, I will then provide guidance for the fiscal third quarter of 2019.

Our September quarter financial results were good. Our consolidated non-GAAP net sales came in just above the midpoint of our guidance that we issued on August 9, 2018. Our consolidated non-GAAP gross margin was strong at 61.7% of sales. Microchip classic, non-GAAP operating margin was an all-time record. Consolidated non-GAAP operating profit, including Microsemi was 38.3% of sales and near the high end of our guidance. Our consolidated non-GAAP EPS was an all-time record at $1.81 and near the high end of our guidance. There was a strong EPS contribution from both Classic Microchip and Microsemi, the accretion from Microsemi exceeded our original guidance of $0.15 for the September quarter. This was based on non-GAAp revenue which is based on distribution sell-through and is representative of real market demand. On non-GAAP basis, this was also over 112th consecutive profitable quarter.

Now let me provide you some update on the progress we have made with the Microsemi integration. First to distribution inventory. We had told you last quarter that we will complete a distribution inventory reduction in two quarters, September and December. I'm pleased to report that with a lot of work by the combined teams of Microchip and Microsemi and in cooperation with the distributors, we almost completed the inventory reduction in one quarter. The distribution inventory at the end of September was 2.62 months, down from about four months prior to the closing of the acquisition. This level of inventory, we believe is the level distributors need to support in market demand and is in line with the level maintained by distributors for Microchip classic business. This was accomplished without any negative impact on distribution sales out, the non-GAAP net sales from Microsemi based on direct shipments and distribution sales out was an all-time record.

Second is termination of deals. Since closing the Microsemi acquisition on May 29, 2018, we terminated deals, discounts and subsidies that were used prior to the acquisition in connection with sales into distribution and contract manufacturers. For example, we can sell the Aero supply assurance program concerning sales into the channel of end-of-life product. At acquisition close, there was approximately $47 million of inventory in distribution under this Aero supply assurance program. We won't take any inventory back, but we will not ship anymore into distribution under that program.

We also canceled the interest subsidy there was offered to some distributors to compensate them based on the inventory they have. We also canceled the production incentive program under which there was a discount offered to contract manufacturers to take additional inventory. Cancellation of this program has had no negative impact on contract manufacturers willingness to purchase the product they need.

Finally, there with a number of OEM customers that were transferred to distribution and then the inventory shipped into distribution. This resulted in lower margin for Microsemi. As of today, we have transferred many of those customers that account for about $110 million of annualized revenue back to direct customers. So overall, we are pleased that we were able to reduce some Microsemi distribution inventory very rapidly. There was one business unit, call the high reliability discrete products business unit where the inventory at the end of June was very high at 8.6 months.

At the end of September, we had brought it down to 6.7 months. We are continuing to reduce the inventory for this business unit further. The shipments are now quite linear in the four quarters prior to being acquired by Microchip, about 57% of Microsemi's quarterly sell-in revenue were shipped in the last month of the quarter. In the September 2018 quarter, only 31% of sell-in revenue from Microsemi products were shipped in the third month.

Now next is Microsemi internal inventory. It is obvious that as we reduce the distribution inventory, the inventories that Microsemi would grow substantially unless we took corrective actions in the factories and subcontractors by cutting production targets. And that is what we did. Fortunately, a very large amount of Microsemi business was done from wafer foundries and assembly and test subcontractors. We aggressively cut wafer starts at the foundries and loadings at assembly test subcontractors.

Microsemi had several small fabs in assembly locations owned by Microsemi. We cut loadings in these factories quite substantially, some of them as much as 50%. We let go temporary workers in many of these facilities and implemented temporary plant shutdowns to control inventory. Microsemi did not produce a high percentage of their products inside. So the gross margin impact was fairly small. We maintained over 61% overall gross margin for Microsemi. We believe that the under loadings of the factory has got somewhat counterbalanced by the discontinuance of all the discounts. But as I have said before, the results are going to be a bit noisy for a couple of quarters.

At the end of September, the overall inventory, internal inventory at Microchip, including Microsemi was 117 days, down two days from 119 days at the end of June quarter. So we did a great job in controlling internal inventories. Now, this may seem all too easy after the fact, but there was a tremendous focus and amount of work that went into reducing the distribution inventory. And at the same time, ensuring that our internal inventory does not belong up. We have multiple joint teams from Microchip and Microsemi, some focused on distribution inventory reduction, others focused on controlling internal factory production and others managing reduction of foundry wafer starts and assembly and test loadings.

So while addressing the inventory has provided some headwind on the distribution selling driven GAAP revenue, including sales to contract manufacturers. The non-GAAP revenue for distribution, which is based on sell-through has not been affected. I'm pleased that Microsemi business achieved a record non-GAAP net sales based on end market demand. The second issue we highlighted last quarter was extravagance. In this area, we have been moving aggressively to implement Microchip's frugal expense culture. We have shutdown the executive floor at the Microsemi headquarter building, canceled the private jet account, terminated or sold many of the sport's sky boxes, canceled golf and auto racing sponsorships and substantially prune the many memberships.

As we reduced inventory and spending, Microsemi business has continued to do well. This was a negative from the beginning that Microsemi has very good engineering teams and has very good products. The customers sockets are sticky and there are good end market opportunities for the combined company. Our strategy for the better part of this decade has been to buy businesses and turn them into world-class performers in the likes of Microchip. Here, we are starting with excellent products, excellent gross margins and excellent engineering teams. With the distributor and contract manufacturing inventory reduced and with Microchip's operating expense approach, we are optimistic about achieving our long-term targets for attrition from Microsemi.

So far, we are ahead of our original targets. I also want to provide you one more figure. In the September quarter, we paid $501 million of our debt. This was accomplished by squeezing all the cash out of nearly 100 subsidiaries around the world. We could not have done it without the new tax law. Despite the large debt pay down in the September quarter, the debt leverage has not moved, though, primarily because the EBITDA has dropped, driven by lower GAAP revenue of Microsemi and also some softness in the Microchip classic business.

I also want to provide you update on our Classic Microchip business, all of the issues that I highlighted last quarter, that was built into our guidance essentially came true. I had described four concerns. First, long lead times for some of the passive components. This issue did affect from sales as we expected, since the customers could not complete the whole kit. Number two, tariffs. While we were one of the first to highlight the risk of tariffs and trade war, this issue investor and analyst attention during the quarter for the whole industry. We saw a significant impact on our business during the quarter due to customer concerns about tenants and we saw a significant weakening of our bookings. We believe that tariffs and related customer concerns will continue to be an issue. Number three, ZTE. We saw some impact from not being fully able to ship to ZTE for both Microchip and Microsemi, despite the release from the Justice Department, there has been some demand destruction at ZTE. And number four, Bitcoin. Our bitcoin business has essentially evaporated, it was about 1% of our business, supplying microcontrollers and power management products for the power supplies, as well as Ethernet controllers.

Now, I will provide you guidance for the December quarter. The guidance we provided for the September quarter, which reflected our caution on business conditions turned out in retrospect to be spot on and was a harbinger for broader industry weakness. We continue to be cautious about the outlook for the December quarter. We see weak market conditions for automotive and industrial, our two largest markets. Automotive business is negatively impacted by emission testing bottlenecks in Europe as well as weakness in China. The industrial business is negatively impacted by tariffs. On the other hand, communication, data center and aerospace and defense businesses are seeing strength.

With all this commentary, we expect our total non-GAAP net sales to be down 5% to 10% sequentially. We expect our non-GAAP gross margin to be between 61% and 61.5% of sales. We expect non-GAAP operating expenses to be between 24.9% and 25.4% of sales and we expect the non-GAAP operating profit percentage to be between 35.6% and 36.6% of sales. And we expect non-GAAP earnings per share to be between $1.49 and $1.64 per share. Given all the complications of accounting for the acquisitions including amortization of intangibles, restructuring charges, inventory write-up on acquisitions and changes in distribution inventory, Microchip will continue to provide guidance and track its results on a non-GAAP basis, we believe that non-GAAP results provide more meaningful comparison to prior quarters and we request that the analysts continue to report their non-GAAP estimates to first call.

With this operator, will you please poll for questions?

Questions and Answers:

Operator

Certainly. (Operator Instructions) We'll hear first today from Christopher Rolland with Susquehanna.

Christopher Rolland -- Susquehanna -- Analyst

Hey guys, great quarter in light of some of the headwinds that we're having here and great update on Microsemi as well. So Steve, maybe you can just elaborate a little bit more on some of the end markets there. You had a little bit more detail than others did perhaps on auto, maybe talk about industrial as well. And then some bright points maybe within data center and comps, maybe that's your optical business that you might be pointing to, any more details there would be great.

Steve Sanghi -- Chief Executive Officer

Well, if you look at the auto business, we highlighted two areas, one is there was a new emission standard implemented in Europe, effective September 1. There was a one year notice on it almost from September 1 of the prior year, however testing agencies couldn't build up the capacity to test all the car production. So there was a significant bottleneck for cars waiting to be tested which brought the European car production down. And the whole China economy has been weak due to various reasons, some incentives were taken away, the concerns about tariff in Chinese production and all sorts of other reasons, China automotive market has been weak.

In the industrial area, the concerns are mainly tariffs, both driven by Chinese end products coming to US which have a 10% duty today going to 25% in January. So there are a lot of people concerned about whether they will be competitive or not in selling products in U.S. and because of weak Chinese economy, Industrial is weak in China too. The three markets which are doing stronger are data center, communication and defense and aerospace. If I take them in the reverse order, defense and aerospace, I think after years of drawing down defense spending, the defense and aerospace spending has been on the way up. And we are very broadly designed in into essentially every single weaponry system, every single aircraft, helicopters and others. So that part of the business is doing well.

The data center business, I think you probably have seen some other companies with higher exposure to data center, data center cloud, hyperscalers and all that, that part of the business has been stronger. So that business did well last quarter and is stronger relative to the automotive and industrial and other businesses. And third is the communication, I think we also see the communication business doing well.

Christopher Rolland -- Susquehanna -- Analyst

And you guys have talked about this potential weakness that we're seeing from most guys out there in the market a little bit earlier, some however haven't guided for much weakness at all. Do you think that perhaps they're going to see it a little bit later and you might be working through this process a little bit earlier? And then, are there any signs of stabilization in late October or early November?

Steve Sanghi -- Chief Executive Officer

Well, we are not going to talk about what other companies have said or what may happen to other industry players. I think you should ask them. Regarding Microchip, we first saw some impact in June quarter. And what we were seeing in June based on that we had a fairly conservative guidance for the September quarter and most people didn't talk about it till the results for the September quarter. So we were four months earlier before we saw it. And that's not first time, numerous times in the past we have seen the impact of industry events about three, four months ahead of the others see it. And we seed early and we always end early.

If we talk about the industry four months earlier, nobody tends to believe it, because nobody else is talking about it and you're not seeing it. And therefore we start talking about the industry, we just talked about some factors that were affecting our business. So it turned out we were correct again and everybody else saw it later. And now on the other side, we always come out earlier but whenever we tell you that, that won't get believed either because others are not seeing it yet. So we are not fully ready to talk about the other end of the cycle yet.

Christopher Rolland -- Susquehanna -- Analyst

Great. Thanks so much, Steve. Appreciate that.

Steve Sanghi -- Chief Executive Officer

Welcome.

Operator

We'll hear next from Harsh Kumar with Piper Jaffray.

Harsh Kumar -- Piper Jaffray -- Analyst

Yeah, hey guys, thanks for the MSCC update. Congrats on preserving EPS in a tough market. Maybe one for Eric. Eric, I think you had cited a goal of 0.7 turns of delevering for I believe for this fiscal year. Can you maybe talk about if that gets impacted at all with this environment and currently based on what you're seeing? And also maybe one for Steve, and I won't ask a follow-up after this. Microchip was usually up in March, I think mostly MSCC was just all over the place. Maybe could you help us think about how we can think about modeling March just from your initial read on what you've seen in the business?

J. Eric Bjornholt -- Vice President and Chief Financial Officer

Sure. So I'll take the deleveraging one first and then pass it back to Steve. But we made really good progress in terms of paying down debt as both Steve and I mentioned in our prepared remarks, we took down $500 million worth of total debt and on a net basis $315.5 million. So did a really good job there of using all the cash that we could to pay down debt. We will continue to use substantially all of our excess cash generations after dividends to reduce our debt levels. And we expect our net leverage to decline dramatically over the next several years.

Now with the correction of the Microsemi distribution inventory having a significant impact on our EBITDA in the June and September 2018 quarters and then combining that with our guidance for the December 2018 quarter, our trailing 12 month EBITDA will have significant headwinds over the next year. And our net debt to EBITDA will not trend down as fast as we had indicated back in August, but this is a very good cash flow business, like I said, we'll continue to pay down debt, but in the current quarter we probably expect that debt paydown to be somewhere in $160 million range, a broad range should be $150 million to $200 million, but we'll have to see how things trend here over the next few quarters to give you a longer-term forecast.

Harsh Kumar -- Piper Jaffray -- Analyst

Got it.

Steve Sanghi -- Chief Executive Officer

So I'll pickup the second question you had which was regarding the March quarter. So I remind investors that when we bought Atmel, it was not a small acquisition, either. Atmel was about 40% to half of our business. And after we integrated Atmel, we didn't understand Atmel's seasonality for awhile because companies on their own, their prior seasonality was based on sell-in, however, they work for the distributors, the whole end market mix was different. And after we had Atmel for the entire year or more than a year, we fully understood the impact of Atmel seasonality on our business to be able to guide properly.

Same is the situation now with Microsemi. We don't fully understand Microsemi's seasonality. We haven't had a March quarter where the Microsemi in it. And we do not consider the March quarter on a Microsemi's clot to be a meaningful indicator for us regarding seasonality because that business was managed with a selling driven mentality, with a significantly high distribution inventory, our guidance will be based on real market demand. So -- and the end markets for Microsemi are quite different. They are stronger in defence, stronger in data centers, stronger in communication and almost no automotive, very little automotive and all that.

So I'm not ready to talk about the March quarter in terms of guidance till we have some more experience on our belt in understanding their seasonality as well as being able to gauge the impact of the current correction when it is ending and how its impact would be in the March quarter.

Harsh Kumar -- Piper Jaffray -- Analyst

That's fair. Thanks, Steve.

Operator

We'll hear now from Craig Ellis with B. Riley.

Craig Ellis -- B. Riley -- Analyst

Yes, thanks for taking the question. I'll start with a clarification with respect to the strong performance on the Microsemi inventory cleanup in the quarter. Did that have a particular impact on any of the product segment revenues that you reported or was the impact spread about equally among MCUs, analog and other businesses?

J. Eric Bjornholt -- Vice President and Chief Financial Officer

So, it really did not have an impact on the sales-out activity that Ganesh talked about, breaking out by product lines. So it was really just more of correcting the inventory sitting in distribution. So I don't think there was really any end-market impact from the actions that we took.

Steve Sanghi -- Chief Executive Officer

We basically, we haven't broken out the sell-in data by product line. We only have broken out sell-out data by product line and that did not change based on lowering the sell-in and cleaning up the inventory.

J. Eric Bjornholt -- Vice President and Chief Financial Officer

Yes. So, I mean, we have the sell-in data in our public filings and in our 10-Q, but that doesn't really give you an indication of where the distribution inventory drain was by product line.

Craig Ellis -- B. Riley -- Analyst

Got it. And then the follow-up. There were a couple of references to accretion and I just wanted to clarify, what was the exact amount of Microsemi earnings accretion in the quarter? And Steve, are you retaining all the prior synergies and accretion targets, the $300 million in synergies as well as the $0.75 plus in year one (ph) and $8 and I believe fiscal '20 earnings?

Steve Sanghi -- Chief Executive Officer

Yes, we're not breaking out the exact numbers of Microsemi attrition because we kind of managing it as one company, but we gave you anecdotes that the accretion in the September quarter was higher than the $0.15 for the September quarter, we had originally guided. And we feel very confident that going out of the first year, the accretion will be higher than the $0.75 that we guided and we remain committed to a longer-term accretion of earnings per share of $8 that we guided before. This is a short-term impact based on this business cycle environment, whatever one, two, three quarters at last, it doesn't really have a long-term impact over a three, four years because usually the bounce back, will get you back to where you were.

Craig Ellis -- B. Riley -- Analyst

From SunTrust, we'll hear from William Stein.

William Stein -- SunTrust -- Analyst

Great, thanks for taking my questions. First, really more of a housekeeping one. The share count was a little lower than expected in the quarter and in the outlook. Is that just owing to a share price and the treasury method accounting for average shares in the quarter? Or is there something else going on there?

J. Eric Bjornholt -- Vice President and Chief Financial Officer

No, that's exactly what it is. We post a schedule on our Investor Relations page under supplemental financial information that walks through what the share count approximately would be based on various prices. As you know, we have several convertible debt instruments outstanding and the share dilution from those has gone down with the stock price falling.

William Stein -- SunTrust -- Analyst

That helps. Thank you. And the other is to address the GAAP to non-GAAP revenue adjustment. I think it was $81 million in the quarter. You noted that the channel inventory from Microsemi now approximates the sort of heritage Microchip business channel inventory. So it sounds like maybe there is little bit more work to do, but it's mostly done. And so, while I understand that just the inventory is going to fluctuate somewhat quarter-to-quarter after this $81 million delta that we saw in the quarter you just posted, going forward, should we expect this number to sort of fluctuate around zero or average around zero over time? Is that the right way to think about it?

J. Eric Bjornholt -- Vice President and Chief Financial Officer

I'll take a stab at answering that and then Steve or Ganesh can chime in. So, we're really pleased with the progress that we made in getting the Microsemi just the inventory down to 2.62 months, which is right in line with where Microchip has been historically. We really are not able to project what distributors are going to do, some of that is going to be based on environment, it's going to be based on working capital needs, it's going to be based on lead times, there are so many things that factor into it. We have 120 or so distributors that we work with worldwide. We don't manage our business in a way where we get that type of visibility from them and really we're driving for end-market demand forecast versus sell-in.

When it surprise me in an environment like this, that distributors are going to be very tight with our working capital. But again, for us to be able to provide any sort of forecast of what it's going to do is quite difficult and we don't feel we have capability to do that. Steve, do you want to add anything?

Steve Sanghi -- Chief Executive Officer

What I would add is, we do not put any effort into managing our business to put the inventory into distribution. We put our entire effort into creating market demand which pulls the inventory out of the distribution and then allow the asset managers of the distribution to buy the product they need to serve the end market demand. So as the quarter is approaching, the quarter-end is approaching, we don't look at sales out is this and sell-in is this and we got to go make another $10 million of deal. So sell-in is lower than the sell-out or to hold back product because it's going to go up or lower. We don't manage both of those numbers. We only manage one number which is sales out.

And like I told you last quarter, the standard has changed, the GAAP standard is sell-in. I told you that before we disagree with it. But we have to report a GAAP sell-in number which we do, and we'll continue to do it. But all our measurements, all our bonus programs what Board manages us is to a market demand driven number that we report as a non-GAAP revenue. And sell-in would be whatever distributors want based on their own asset management, their cash flow needs, lead times, there are hundreds of things go into what they do with their inventory. And we don't manage that.

We'll hear now from Craig Hettenbach with Morgan Stanley.

Craig Hettenbach -- Morgan Stanley -- Analyst

Yes. Thank you. Steve, understanding, you don't want to talk about the March quarter and seasonality yet, just for the core business, your commentary about kind of cautious into December, what type of signals are you looking for in terms of distribution, our customers in terms of how far along we are for the correction here?

Steve Sanghi -- Chief Executive Officer

Well, we interact with a large number of customers and distributors over the course of this quarter. And based on that collective engagement with hundreds, if not thousands of customers in all three geographies, US, Europe, Asia, we will have an assessment by the time we announce the December quarter results, which will be in early February. If there is a meaningful information that developed before that and gives us enough data points that we can kind of make a call, then we'll use the opportunity at one of the conferences to make comments on it. But fresh coming from the elections yesterday with 1% of precincts reporting, we cannot make the call on the election.

Craig Hettenbach -- Morgan Stanley -- Analyst

Understood. And appreciate the color on the end markets, where you're seeing strength and weakness, any thoughts on consumer appliances, because that's the market that we've seen some potential slowing in China as well, do you have any thoughts there?

Ganesh Moorthy -- President & Chief Operating Officer

So that part of the business appliance consumer part of the business is weak also. I cannot put it in the industrial. People who make wave conditioners and appliances and that's kind of industrial kind of business, you may call it consumer, but yes, that is we call so.

From Stifel we will hear from Kevin Cassidy.

Kevin Cassidy -- Stifel -- Analyst

Thanks for taking my question. With reference to China, have you seen any change in behavior on new designs where -- maybe because of the tariff and trade war if there's preference for non-US microcontrollers as an example, rather than Microchip?

Ganesh Moorthy -- President & Chief Operating Officer

We haven't really seen a lot of impact in reality. There is lot of talk about it, but it's not changing the funnel size in any way, partially because very large portion of Microchip business is proprietary, such functionality with such low power or such features or performance for that really is not available in any local kind of Chinese parts, which are really fairly low end. So I don't think we have seen any meaningful difference in the funnel size or design activity. There is a lot to talk about it.

Steve Sanghi -- Chief Executive Officer

Yes. And maybe I didn't understand the question directly, but tariff impact on our products directly is very, very small, right. It's the products that our customers are building with our products where the tariff applies. So I think it's probably too early for us to see any real impact on the design side, Kevin.

If they were to use the Chinese microcontroller or analog part to build their end product appliance or washers and dryers whatever that will have duty also coming in here. So not designing a Microchip product does not abate the duty coming into US. And that is a bigger impact.

Kevin Cassidy -- Stifel -- Analyst

Right. It's just more whether it's going to anti-US, view in the design point of view, even if it's an STMicro (ph) something from Europe, rather than the US-based, that's what I was trying to get.

Steve Sanghi -- Chief Executive Officer

I think your question is the right one and we hit that, but like I said, fortunately we're not easy to design up.

Kevin Cassidy -- Stifel -- Analyst

Okay, great. Thank you.

We'll hear next from John Pitzer with Credit Suisse.

John Pitzer -- Credit Suisse -- Analyst

Yes, guys, thanks for letting me ask questions. Congratulations on the good results. Steve, relative to the industrial weakness should calling out tariffs. I know this is probably an impossible question to answer, but I'm going to ask your opinion anyhow. To what extent do you think customers are reacting to the 10% tariff that's already been levied? And to what extent do you think that they're actually trying to be anticipatory to the raise to 25% come in the beginning of the year, I'm just trying to get a sense as to whether or not you think there's another sheer to drop or not?

And then my second question, you did a great job kind of talking about the distribution inventory at Microsemi. I'm kind of curious about direct customer inventory. What did you see as the quarter unfolded? Was there any meaningful adjustments you needed to make there those behind you and to the extent they might be behind you, could there be a potential tailwind which I think you referred to on the last conference call once this inventory depletion was done.

Steve Sanghi -- Chief Executive Officer

So let me take the first one first, which is a tariff question. So what's happening is as the percentage tariff and the products which are -- we've tariffs on keeps moving, it is kind of creating waves in customer sentiment. Originally, back in June-July time frame when there were some tariffs ready to go on in August, some people will try to get ahead of it, build the product, so they bring it to US and avoid the tariff, others will hold back production, they want to draw down their inventory, because they don't really know whether they'll be able to pass the tariff to the customers or they will agree that entire tariff.

So it kind of create some waves both ways and that was for the 10% tariff. And through the quarter of September, customers were essentially cutting down production, drawing down their inventory, because they felt that it will be uncompetitive passing on the tariff to US customers who had a choice to buy the product made in Taiwan, made in Singapore, made in Vietnam, made in Mexico or wherever. And now, very recently we're hearing the talk that the expectation many of the customers had was heading toward the elections, the whole thing we're going to get settled. You may recall at the UN, Trump was talking so bad about Canada that Canada was cooperating and all that, and there maybe an agreement with Mexico only. One week later they signed an agreement announced the agreement with Canada, so the thought was similarly few days before the election there will be settlement with China and so kind of people who are holding back. Well, that didn't happen. And now the feeling is I don't think the settlement is closed. So now some of the customers are thinking tariffs are going to go to 25% and we should pull in and built some of the stuff and bring to US at 10% tariff and then bringing to 25%. So you could see that the waves moving all over the place and 50,000 customers we might have in China, not all aligned. It's very noisy, it's very hard to make decisions and we had lead times are short and we're responding to every customer and they're signing as we see it. So I don't know if that answers your first question.

John Pitzer -- Credit Suisse -- Analyst

No, that's helpful. And then just on the direct customer inventory situation of Microsemi?

Steve Sanghi -- Chief Executive Officer

On the direct to customer, the inventory we saw on the direct customer side was with contract manufacturers, because contract manufacturers is considered OEM business, it's a direct business, it's not through distribution. There was really not much inventory in the direct customers that we saw. And we wouldn't know it either, I mean, you don't know every customers inventory, but the way the deals were made with the discounts were given were to the contract manufacturers under a program called Production Incentive Program. So we can fill that program. And as we cancel that program, contract manufacturers only started taking what they need for their needs and they drew down their inventory.

John Pitzer -- Credit Suisse -- Analyst

Perfect, thank you.

(Operator Instructions) We'll hear next from Chris Danely with Citi.

Chris Danely -- Citi -- Analyst

Hey, thanks guys. Steve, I know you're not going to comment on March seasonality. If hypothetically speaking if March revenue was down, would you be able to keep OpEx flat to down ?

Steve Sanghi -- Chief Executive Officer

Well, we definitely will have the March OpEx down, not even flat to down, will be down, because we are still continuing to reduce Microsemi expenses as we do integration. And if March quarter is down as we're supposing, bonuses would be lower, so bonus approval will be lower. Yes, so I would say in that situation, March expense will not be flat, they will be down.

Chris Danely -- Citi -- Analyst

Okay, great. And then for my next question, any sort of comparisons on this correction versus previous corrections? Are you seeing anything in common or this completely new?

Steve Sanghi -- Chief Executive Officer

Well, I think that's more of your department than and mine, but...

Chris Danely -- Citi -- Analyst

I'm just newest as you...

Steve Sanghi -- Chief Executive Officer

In 2015, we saw this impact, I believe in August-September time frame. And we made a call I believe in late September time frame that we see China slowing down. It was driven by China and nobody else was seeing it and by -- and then when the numbers came out and numbers were cut, and they were cut again and everybody was down as much. And most stocks went down lower than they had gone down that day when we had made the call. So everybody was about four months behind. Same thing is happening this time. I think we saw that impact three to four months behind everybody else, so that is common. But what's driving it today versus what was driving it back then, I think the reasons are a little bit different, tariffs, maybe lead time becoming shorter, some are same, some are different, tariff is a new phenomenon.

Chris Danely -- Citi -- Analyst

Got it. Okay, thanks guys.

We'll hear now from Vivek Arya of Bank of America Merrill Lynch.

Vivek Arya -- Bank of America Merrill Lynch -- Analyst

Thanks for taking my question. Steve, for the first one, can you give us some more real-time sense on production plants? Are you still looking to reduce them further versus seasonality or do you think they have kind of stabilized at these levels?

Steve Sanghi -- Chief Executive Officer

Well, so if you look at Chris Danely's question, you have to make an assumption on March. We cut back production quite a bit, with that, the internal inventory is in good control. We actually -- internal inventory went down by a couple of days. So, if the business is stable from here, if this quarter marks the bottom, then factory start building back slowly. If there is a further downside, which was an assumption possibly Chris was making -- I don't know if he was making that assumption, then you have to adjust to the reality.

Vivek Arya -- Bank of America Merrill Lynch -- Analyst

And on the OpEx side, if my math is right, so you had $354 million on non-GAAP OpEx in September, I think December, you are guiding to $352 million, so kind of a flattish. Why are we not seeing more cost synergies? And -- or does it just mean we will see them later on?

J. Eric Bjornholt -- Vice President and Chief Financial Officer

Well, we took a lot of costs out early. I think if you were to combine the Microchip and Microsemi models from back in March or even a year ago, you're going to see that significant expense has been taken out. And that doesn't mean that there still not more to come. But I think we're actively managing that. Our OpEx came in significantly lower than our guidance for the quarter that we just completed. And we're managing based on the environment that's presented to us and I think we're doing a good job of that.

Vivek Arya -- Bank of America Merrill Lynch -- Analyst

Got it. And just one quick housekeeping. I think, Eric, you said tax rate under 5%, I believe in the past it was between 3% to 4%. So, just for modeling purpose, should be more like 3.5% or 4.5% for the next one or two years? Thank you.

J. Eric Bjornholt -- Vice President and Chief Financial Officer

Well, when we gave a 3% to 4% before, that was kind of the short-term and we've got now questions coming in, in terms of what it's going to be over the next few years. And it's not a perfect science to forecast this but under 5% or 5% or less is where we're at today, it's not saying it can't be 3.5% but that's a pretty tight range.

Steve Sanghi -- Chief Executive Officer

I think you're modeling 100 plus subsidiaries around the world and varying tax rates in various countries and interest payments and deductions and all these taxes and it should kind of average of all that, it's not a perfect sound, so it can change based on mix.

Vivek Arya -- Bank of America Merrill Lynch -- Analyst

Got it. Thank you.

Moving on to Mark Delaney with Goldman Sachs.

Mark Delaney -- Goldman Sachs -- Analyst

Yes, hi, good afternoon, and thanks for taking the question. The first question, I was hoping you could help us better understand some of the trade-offs that you've made with Microsemi's business now that you've had it under your wing for a longer period of time. It sounds like there's been several efforts taken to improve gross margins and I think that business had run in the low 60s on a stand-alone basis. With all the changes, some of the product pruning and that changed things along those lines, do you think it gets to above that 63 range that you're guiding for on a combined basis or that were just toward that higher end once the utilization rates normalize? And related to that, maybe you can help us think about, has there been any share shifts or the size of product pruning that you may have done given some of these changes that you're making to the business model?

Steve Sanghi -- Chief Executive Officer

I think, Mark, one mistake most people make in looking at Microsemi gross margin is that day-to-day acquisition of a company called Vectron which closed in late November, early December timeframe. It had gross margins in the mid 30s and was $100 million revenue. And so, its impact was really never seen by investors in a non-GAAP basis. December quarter was fairly short just one month. And then March quarter, we announced the deal on March 1. So March quarter was really never fully announced based on a non-GAAP.

Mark Delaney -- Goldman Sachs -- Analyst

All right. They filed the 10-Q.

Steve Sanghi -- Chief Executive Officer

Yes, they filed the 10-Q.

Mark Delaney -- Goldman Sachs -- Analyst

But didn't have a conference call --

Steve Sanghi -- Chief Executive Officer

But didn't have a conference call. So you wouldn't really know the non-GAAP margin taking away all these charges and everything else that acquisitions do. So Microsemi gross margin wasn't 63% driven by all those acquisitions margin was below 60%. And so we have already improved some and we'll continue to improve the gross margin, but looking for the gross margin to go over 63% would be quite a stretch right now.

J. Eric Bjornholt -- Vice President and Chief Financial Officer

Yes, so we -- as you said, have margin improvements programs that are in place and we still have confidence in the combined long-term model of 63%, this last quarter, we were at 61.7%. So it's not like we're light years away from that but --

Steve Sanghi -- Chief Executive Officer

We got to get the factories to full production again because of the inventory correction as you ship less to distribution, all that inventory stays in house unless you cut production, so we did. And we take the under-absorption in the current quarter, we don't put it into -- we don't capitalize it into the inventory. So as the production starts going back, you will have some accretive effect on gross margin.

Mark Delaney -- Goldman Sachs -- Analyst

That's helpful. And then just -- for the second part of that question, obviously there is a different focus on the types of businesses Microchip will be participating with there, but can you just help us think about the scope of revenue that you may not participate in any more either because you're focusing on -- and there are set of product lines, any share shifts that we should be contemplating things along those lines, so we can think about the right revenue run rate for that business once we adjust for some of these inventory dynamics that have gone on the last couple of quarters?

Steve Sanghi -- Chief Executive Officer

So, we said that before we are going to keep and we like all the businesses. The combined Microsemi all businesses together, P&L is very good. There are product lines which are lower gross margin, there are product lines which are higher gross margin than average, there are product lines that grow less than average, there are product lines that are growing more than average. Microchip classic is no different. Our gross margins are lower in certain Microchip businesses but mix and match overall gross margin is excellent and that is the case with Microsemi. Every business is accretive and we're not going to offload a business just because it's a lower gross margin than the average. If it's accretive and growing and adding and providing additional attach is a part of the total system solution. So if all the other things are working, then it's a good Microchip product.

J. Eric Bjornholt -- Vice President and Chief Financial Officer

And every business unit leader that we have is tested and not just growing the revenue but improving their gross margin and operating margins over time. And with -- in the Microchip system, we work together to make that happen.

Mark Delaney -- Goldman Sachs -- Analyst

Yes. Thank you.

We'll move Next to Krysten Sciacca with Nomura.

Krysten Sciacca -- Nomura -- Analyst

Good evening. Thanks for taking my question and congrats on the great execution of Microsemi. I just wanted to follow up on the OpEx question from before. It looks like the OpEx from this quarter came in a little bit lower than expected. And I'm just wondering if that was just due to better than expected execution on synergies or was there something else, going on in the quarter there that we should be thinking about?

Steve Sanghi -- Chief Executive Officer

There was nothing else going on. Although, we would say that since we saw the effect of this downturn coming much earlier than anybody else, we hunker down earlier. We can sell majority of the open wrecks, we cut back on capital, we canceled firm orders that we had in capital to the extent we were able to cancel them and that's we slipped them out. We hunker down and we kind of batten down the hatches.

J. Eric Bjornholt -- Vice President and Chief Financial Officer

We ask our employees to treat the spending as if it's their own money and do that on a global basis and it has very good results. So I think Steve is right. We just got out ahead of this quicker.

Krysten Sciacca -- Nomura -- Analyst

Okay, great. That's helpful. And then just moving to the inventory question from Microsemi and how you completed that about a quarter earlier, then you stated on the prior call for the most part. What exactly caused that faster, that correction to happen faster than expected? Was there something in particular that Microchip did, or was it just better end demand, or what was kind of driving that for us?

Steve Sanghi -- Chief Executive Officer

So, I think, especially when you buy new business, you're in lot to learn for that business. You're getting to know the people that are concerned with employees regarding what Microchip could do with various businesses. Let me get this in, various analysts write about various businesses that we will sell out, we should sell. And I always ask you please don't do that, because you create problem for us. The employees of that business read those reports and they get concerned that their business is maybe sold or not get focused on. And we have said that we're going to keep all the businesses, but every time you look at some analysts will make this speculation why data center business doesn't fit with Microchip and Opto (ph) doesn't fit with Microchip or something else doesn't Microchip. All that does is creates concern for our customers and creates concern for our employees.

So what I'm saying is, we are working very hard on all these items, learning the businesses, keeping the customers at peace, talking to the employees, learning the inventory, and when such a large challenge comes up like the inventory, then it just takes an enormous amount of energy forming the teams and focusing the teams to go clean up the inventory. It also depends on how in the mix that inventory was. If that inventory was highly out of mix, then you have to continue to ship additional products for which there is demand. And if there is lot of slow-moving inventory that we call sludge, then that will take much longer time. And in certain business units, the inventory was in good mix. And certain other business units, inventory was not as good as a mix. So basically, huge amount of work, the combined teams are working together, creating a goal for everybody to clean up this inventory faster than the two quarters we guided to. And I think that's where we are. And also working in coorporate -- getting cooperation from the distributors.

Krysten Sciacca -- Nomura -- Analyst

Excellent. Thank you.

Steve Sanghi -- Chief Executive Officer

It's just lot of groundwork, there is not much magic there, it's just a lot of hard work.

J. Eric Bjornholt -- Vice President and Chief Financial Officer

And as Steve mentioned in his prepared remarks, there is still a business unit or two, that's inventory is higher than we'd like it to be and it will come down over time. And there may be a business unit or two, that's inventory is too low. And these things kind of balance each other out. So we think at 2.6 months, we're in a very good position today.

Steve Sanghi -- Chief Executive Officer

And in this business unit, number one, the inventory is very high over 8.6 months. Clearly, there was a lot of excess inventory. And when you build that much inventory, then inventory also tends to age and gets out of mix, we shipped such a high amount of inventory and customer demand shifts. So lot of the inventories becomes very slow moving and takes time to correct.

J. Eric Bjornholt -- Vice President and Chief Financial Officer

I guess I'll give kudos to all the business units that were involved, the sales and distribution organization, our distributors, the planning folks, just it was a very large team, and everybody did a good job of executing.

Steve Sanghi -- Chief Executive Officer

There was also $110 million of product that we shifted back from distribution to direct and customer by customer and distributor by distributor whichever the pair was, the distributor shipping to customer, you had to go work that relationship and convince a customer and convince a distributor, distributor going to lose that business to direct customer will ship it directly, makes sure distributor cleans out their inventory, so the new business and Microchip ships and creating accounts for those customers, receivables, learning where the product has to be shipped some places, sometime it goes into hubs of distributors. Sometimes there are multiple locations, all that challenging task by the shipping teams and marketing teams and sales teams, it's just purely a guess when we first talked to you regarding how long would it take. I have to tell you, two quarters and get it done in one quarter, rather than tell you one quarter and takes two quarters.

Krysten Sciacca -- Nomura -- Analyst

For Raymond James, we'll go to Chris Caso.

Chris Caso -- Raymond James -- Analyst

Yes, thank you. Thanks for taking the question. Just a question with regard to customer inventory levels, and I'd say, it's probably more pertains to the Microchip classic business. How much of the slowdown that you're seeing now, do you attribute to some of the demand function, issues that you talked about as opposed to just customers holding too much inventory and typically when we've seen the slow downs in the past, it's some combination of the two, do you think about it any differently at this time around?

Steve Sanghi -- Chief Executive Officer

Well, when customer buys less product, you're unable to differentiate whether that's a purely inventory correction or his demand is slower. It always tends to be a combination. If you're building a 100,000 widgets a week, then you have certain amount of inventory at you're loading dock, in your factory floor, some in raw material, some in work in process, a certain amount of inventory. If your demand drops, because of your tariff concerns, let's say, you only want to build a 90,000 widgets, then the entire inventory in your structure divided by 90 is going to become more weeks of inventory than at 100. And then when you draw it down, you could call it inventory correction, you can call it because of the lower demand, I don't know how you separate it.

Chris Caso -- Raymond James -- Analyst

Understood. As a follow-up, if you could talk about the linearity of your order rate as you proceeded through the quarter and into October. And I assume that that the order rates have slowed down since we last spoke in August, but have they sort of step down to a certain level and then stabilize that level given the uncertainty about tariffs and such, you spoke about or did they continue to worsen on a month-on-month basis?

Steve Sanghi -- Chief Executive Officer

The order rate slowed down and stayed pretty constant at the lower level and have recently bounced back, partially because lead times are fairly short, so they got to place the orders for December and January. They don't need to place orders for next June, but they do need to place the orders for the next quarter. So the order rate, as you said, slowed down, but has recently bounced back up.

Chris Caso -- Raymond James -- Analyst

In the month of October?

We will hear next from Vijay Rakesh with Mizuho.

Vijay Rakesh -- Mizuho Securities -- Analyst

Just wondering on deleveraging, how you changed, are you accelerating that? What's -- how are you looking at that?

J. Eric Bjornholt -- Vice President and Chief Financial Officer

So I tried to answer that on a earlier question, but essentially our deleveraging is going to be at a slower pace than what we had originally guided to the Street. We've got headwinds of very low EBITDA in both June and September, due to discretion inventory reduction. We were having a down quarter this year at the midpoint of guidance. We're going to be down 7.5%. And that just have an impact and is going to stay with us now for 12 months, because this debt calculations or EBITDA calculations are all 12 month trailing. So the cash flow from the business is going to be high, but if you look at our accounts receivable balance, it's down $120 million quarter-on-quarter, and that translates to cash. So it's going to take us some time, but all of our cash, really all our significant cash in excess of what we need to run the business and pay dividends is going to be used to pay down debt. And with that, we will reduce the debt balance, but the EBITDA is going to be something that sticks with us for the next year.

Vijay Rakesh -- Mizuho Securities -- Analyst

Got it. And just a follow-up here. Getting fast some of the near-term tariff issues, the lack of visibility into the March quarter and first half, let's say, any thoughts, concerns on microcontroller has been, especially as you look at automotive where does content go? And just wondering -- just want to get your thoughts on how you look at that? Thanks.

Steve Sanghi -- Chief Executive Officer

Ganesh, you want to take that?

J. Eric Bjornholt -- Vice President and Chief Financial Officer

Ganesh, had to run to catch a flight.

Steve Sanghi -- Chief Executive Officer

Oh, he had to catch a flight. So I think we are not concerned about the long-term prospects of microcontroller, analog or any of our businesses. Our fundamental frame is being able to sell total system solution into a customer socket, whether it's automotive, whether it's industrial, with microcontroller, analog connectivity products Wi-Fi, Ethernet, Bluetooth, LoRa. And now where there are lots of Microsemi products, including discrete products, FEPS and diodes and RF and other products. I think, there is fundamentally no concern about long-term Microchip, and the design win funnel and all that, are very, very healthy. I think, we're just talking about this impact, some from the tariff, and some from the slowdown in the business. You could go back, there was an earlier question, how it is different, or same as the 2015 cycle? And in that 2015 cycle, some of the assumptions were, like this thing is over. The industry just goes away, and all these things don't get designed in, and you can see how the business bounced back, and we had record quarters and record years and outstanding market share gains and everything else. So there is no long-term concern here, it's a short-term.

We'll hear next from Harlan Sur with JPMorgan.

Harlan Sur -- JPMorgan -- Analyst

Good afternoon. Thanks for taking my question. Maybe just touching on some of the pockets of strength in the business. In aerospace and defense it's obviously very sticky, very high profitability segment. It sounds like, near-term it's kind of doing well. In order for you guys to sort of take advantage of this very profitable area, how much effort is required to get your MCU and analog products mil-aero, rad-hard qualify, is there a lot of work to be done here? Or is the core Microchip team already engaged in cross-selling?

Steve Sanghi -- Chief Executive Officer

So there is a lot of work under way. There was a small aerospace and defense business that we have acquired as part of the Atmel acquisition, which was headquartered in France. And they did business largely with French aerospace companies, and didn't have any market share in US. And after acquiring them, in the last year and a half or so, we've been putting efforts. We expanded the charter to take Microchip standard microcontroller, analog and memory products, and make them rad-hard, recharacterize them to the needs of military and aerospace with broad temperature ranges and all that. So all that work has been under way for the last two years, so in militarising our products.

Microsemi brings even just a much, much higher level of expertise in that area, and about 10x to 15x larger business than Atmel had in aerospace and defense. So in our integration, we have combined the Atmel's aerospace and defense business together with the microspace, aerospace and defense business as one business unit. And that business unit is accelerating, taking Microchip products to market in that segment. So that effort is about a year old, and is really getting significant boost right now. But we're not shipping core Microchip products in military for revenue today. Any Microchip products going into aerospace and defense sector, are still standard commercial products that are bought from distributors, and just kind of use standard commercial product. In some non-sensitive applications, aerospace and defense is allowed to use standard commercial products. The military products, rad-hard products, is an effort under way, but it's not making revenue today.

Harlan Sur -- JPMorgan -- Analyst

Got it. Thanks for the insights there. And then in the FPGA segment, you guys drove record revenues, obviously the Microsemi team built a strong Mil/Aero leadership franchise there. And I think Ganesh talked about some of the new opportunities with the mid-range PolarFire family, which is more for kind of like multi-market applications, but sounds like overall the business is doing well. Can you guys just give us a sense on how strongly the FPGA business is growing on a year-over-year basis?

Steve Sanghi -- Chief Executive Officer

So, I don't have a year-over-year comparison, some, but it won't be valid, because it will be a sell-in by putting in your high channel inventory versus sell-through that we're measuring. So that's why we said based on a sell-through basis, the numbers were a record. It was all-time record. And I don't have a year-over-year comparison, since we haven't had the business for a year. But the business is doing very well. It's doing very well in defense and aerospace, it's doing very well in the multi-market. It has a very good design and funnel. The next-generation architecture, which is Gen5, is just going into market and just introducing at the sample level.

And there is a significant demand pull on that. So I think we are very optimistic about that business.

Harlan Sur -- JPMorgan -- Analyst

Thanks for the insight, Steve.

We'll go next to Jefferies' Mark Lipacis.

Mark Lipacis -- Jefferies -- Analyst

Hi, thanks for taking my question. Just one. Steve, a number of the contract manufacturers with the global footprint, have talked about some of their customers already shifting manufacturing outside of China and accelerated core activity with our customers to do as much. I was wondering, if you were noticing that any evidence or anecdotes on that front? And to the extent that you think that might be causing some near-term disruption? That's all I had. Thank you.

Steve Sanghi -- Chief Executive Officer

You're very correct. We are seeing that, too. So two things are happening. One, if there are two sources of production, one in China and one outside of China, then some attempt is being made to take the Chinese production and sell it to Europe and Asia, and take the non-Chinese production and ship it to US. This way you can optimize, and not pay any duties. Two challenges in that. Number one, it's lot of manual work and most people aren't set up to really differentiate the product where it should go, but manually and then writing some automation, it's really being done. But it's not perfect, because in many cases, the US demand is not exactly equal to the non-Chinese production, and Europe and Asia demand isn't equal to Chinese production. So there are still problems.

So to solve that problem, you're correct, there are many customers, they are moving Chinese production to outside of China, but they are rapidly running into capacity issues. Where the outside factories are full, there was a little bit space, and they're now full, and there is lot more to be transferred from China, but there's no place to put it till they really expand capacity, build more square footage and all that. And that's a slow process. So, yes, we're seeing that.

Mark Lipacis -- Jefferies -- Analyst

Very helpful. Thank you.

And at this time, I'd like to turn things back to Steve Sanghi for any closing remarks.

Steve Sanghi -- Chief Executive Officer

Well, we want to thank all of our customers and analysts for your patience and for your understanding. I think, this has been a tough four months here, but I think we've done a lot of good work in cleaning up the Microsemi inventory. And at the same time, it's really the first acquisition whose timing was such that the wind is not on our back. We did number of other acquisitions, and the timing was great. Here, along with the Microsemi inventory challenges, we're also facing this downturn in the business. And so we're dealing with the dual challenges. But I think we posted a pretty good quarter. And despite sequentially down guidance, I think we're managing the inventory very well. The internal inventories in very good shape.

Overall gross margin, operating margins are still very, very good. And we look forward to really getting through these issues and getting back to our long-term $8 earnings target. So, thank you very much.

And that does conclude today's conference. Again, thank you all for joining us.
