revenue

The iPhone is the most successful product of all time.

Over 1.6 billion have been sold. Including the iOS products it spun off, the total is over 2.2 billion. Of those 2.2 billion sold, 1.5 billion are still in use.

There are about 1 billion iPhone users.

Economically speaking, iPhone sales have reached one trillion dollars. ((The milestone of $1 trillion iPhone revenues was reached in the fourth quarter 2018 during which time the stock price of Apple fell by 40%.))

Since the iPhone launched, Apple's sales have totaled $1.918 trillion. Of those trillions about one half a trillion was accumulated in the form of  income.

Of that half trillion in income, $360 billion was paid out to shareholders ((As a result, the number of outstanding shares has decreased by 29%)). and $131 billion was paid in taxes.

This sounds like a good business, but no business is good if it is static. What makes a business great is dynamism. The idea is to constantly maneuver for a new or enhanced way of doing business as technologies enable entrepreneurs to fundamentally change how value is captured or allocated.

The iPhone story isn't static, the "pivots" or change in direction are several:

• The App Store, a platform for collaborative innovation where millions of developers are offered the chance to improve the product.
• Accessories, a licensing model for third-party hardware that works with the iPhone
• Distribution through multiple channels
• Integration with other Apple Products
• The marketing of older products alongside new ones at reduced prices
• An expanded product portfolio with a broader range of prices
• Trade-in and financing options

Each of these initiatives contributed to the iPhone growth story but the biggest change in business model was the addition of services. Apple Services grew out of the iTunes business that pre-dates the iPhone and was established to provide content for the iPod.

In 2006, the year before the iPhone launched, Apple customers spent $3.3 billion on iTunes, Software and Services. By 2018 the spending rate was $80.5 billion/yr. It's very possible that this year's spending rate will reach $100 billion/yr. This new division is simply called Services today and consists mainly of third-party apps and third-party content sales as well as licensing.

Recently Apple launched a set of new services that it will offer itself. This includes television, films, financial services and news. Apple already has a music service of its own and file storage (iCloud) both of which are offered as subscriptions.

Apps are also allowed to offer paid subscriptions, and that total has reached 390 million, growing at 30 million a quarter with an expected total of 500 million by 2020. That amounts to one subscription for every other iPhone in use.

Some would argue that even with a $43 billion revenue rate, ($80 billion billing  rate) ((The difference is in the way Apple accounts for App Store revenues: declaring only the 30% portion of sales that it keeps as revenues, and not including the 70% that is paid out to developers. The "billing rate" is what consumers spend, the "revenue rate" is what Apple reports.)) Apple's business is still a hardware business and that comes with low margins, potential for disruption, non-recurring revenues and cyclicality.

This is not the case. Apples's business has high margins (64% gross margin for services, 34% for products), has been resilient over 12 years while attracting hundreds of imitators at lower price points, and has loyalty and satisfaction which results in more than 90% re-purchase rates. Cyclicality is driven by seasonality and product lifespans, not competition.

This common misconception of Apple is why it continues to be valued at a deep discount to not only peer companies who are services oriented (Google, Facebook, Microsoft and Amazon) but also at a discount to the overall market (the S&P 500).

Apple, since its inception, has always been oriented around its customers, not its products. The questions asked by management are "what can the company do to deliver experiences and satisfaction" rather than "what products can the company build".

Every company is bound by its capabilities but the best companies re-shape these bounds because they are defined by priorities.

A priorities-driven company habitually re-designs its processes and its resources. A resources- or process-driven company re-designs its priorities as its capabilities change.

Moving as it does between computers, devices, software, services, retail, logistics and manufacturing means that it's not classifiable as an "x" company where "x" is an industry sector. Rather, the company should be classified by the set of problems it seeks to solve (e.g. communications, community, productivity, creativity, wellbeing).

This disconnect between what people think Apple sells and what Apple builds is as perplexing as the cognitive disconnect between what companies sell and what customers buy.

Companies sell objects or activities that they can make or engage in but customers buy solutions to problems. It's easy to be fooled that these are interchangeable. ((They are only correlated. Purchase decisions are not *caused* by a product's existence. The real cause is a combination of need and supply and time and circumstance of purchase.))

Conversely Apple offers solutions to problems that are viewed, classified, weighed and measured as objects or activities by external observers. Again, it's easy to be fooled that these are the same.

This analysis is, of course, applicable to any company. Here I'm using Apple as a lens. This is because it's just so much easier to tell this story with the narratives and anti-narratives that are so widely disseminated.

In the latest Apple Earnings report, Apple announced a few details that are relevant to the forecast of the business:

• The global active installed base for iPhone reached an all-time high at the end of December, surpassing 900 million devices. This represents growth y-o-y in each of five geographic segments, and growth of almost 75 million in the last 12 months alone
• There are now over 360 million paid subscriptions across the Services portfolio, an increase of 120 million versus a year ago. Apple expects to surpass 500 million in 2020.
• The installed base grew to 1.4 billion devices by the end of December. This includes all-time highs for each of the main product categories and all five of their geographic segments.

I added all these data points to the previous reported figures related to installed base, subscriptions and Services revenue.

Note that all the data sets show a linear growth path. Most prominent is the paid subscriptions line which is growing at exactly 30 million per quarter. The new projection of 500 million by 2020 is exactly in-line with this projection.

Note also that active devices and iPhones are on similar trajectories. The figure for active iPhones is interesting because it very closely relates to active users. It's extremely likely that 900 million active iPhones means 900 million active iPhone users. An iPhone is useful if it has a data plan associated and it's a costly proposition for most people to have multiple devices and multiple data plans.

This close relationship between iPhone usage and iPhone users means that we can approximate the entire unique user base for Apple. There might be "10s" of millions of users who use Apple devices but don't use iPhones but there might also be multiple iPhones for some users ((I would be inclined to assume that there are more non-iPhone Apple users than multiple iPhone users.))

So it's very likely that the total Apple user base is between 900 and 1 billion. If it's not 1 billion now then it's very likely it will be 1 billion within 12 months.

In May 2010 I made the prediction that Apple would reach a billion users in 5 to 8 years. The prediction was based on the first 100 million iOS users. The company reached one billion active devices in a bit over 5 years and is about to reach 1 billion users 8 years since.

Apple stated in the latest conference call that very little of Services revenues depends on the any previous quarter's unit sales confirming that Services is driven almost entirely from the user base. With almost a billion users, 90+% loyalty rate, 95% satisfaction, 120 million paid subscriptions and 75 million new users/yr, the analysis of Apple as a services company is becoming interesting.

For the last two years I've been studying the transportation economy and introducing the idea of Micromobility. Simply, Micromobility promises to have the same effect on mobility as microcomputing had on computing. Bringing transportation to many more and allowing them to travel further and faster.  I use the term micromobility precisely because of the connotation with computing and the expansion of consumption but also because it focuses on the vehicle rather than the service. The vehicle is small, the service is vast. ((If you want to learn about the real future of transportation sooner rather than later, do consider coming to the Micromobility California conference.))

One of the elements of analysis for Micromobility is the notion of Unit Economics. The idea is that each vehicle can be seen as an independent business. It requires an investment, has a revenue attached, requires operating costs and fixed costs and finally, hopefully, generates earnings. A fleet's economics is therefore a multiplication of the unit economics by the fleet size. A similar partial construct exists for mobile network operators where the network revenue is defined by ARPU (average revenue per user). In consumer hardware we also have the idea of ASP (average sales price) and BOM (bill of materials) which describe the revenue and variable cost of each device.

In the case of Micromobility the unit economics is more broadly applied in being an entire P/L statement for each vehicle. One example for the e-scooter sharing company Bird is here. If the unit economics of Bird is consistent across geography and time then the entire business can be valued based on one "average unit". Measuring the health of the business can thus be summarized in BOM, Utilization, Lifespan, Attrition and Cost structure or one unit.

For some time now I've advocated a similar approach for Apple.

The idea is to look at each Apple device sold as a black box that requires investment, generates revenue and, given a certain cost rate, produces a profit. Indeed the company has suggested that this is how it measures itself and has now encouraged us to do the same by withholding measurements that misdirect us away from this method.

Unit sales for Apple are like unit production rate for micromobility. It's certainly important to know how many e-scooters or e-bikes can be manufactured and deployed but it's far more important to know how long each one lasts (lifespan) and how frequently it's used (utilization) and what pricing can be obtained for that use or a per-mile basis.

A restriction on unit production could slow the network's growth but it may not affect the demand measured in miles of distance that users need to cover. A lack of vehicles means users will hire cars or walk or transit or perhaps won't take the trip at all. But once supply is provided the choice of micromodes should compel users to use them.

In this view, the Apple business can be seen as a base of devices multiplied by the revenue per device subtracting the cost.

In the latest letter to investors Tim Cook wrote that the total number of active devices has increased by more than 100 million in the last twelve months. Given that the figure a year ago was 1.3 billion, the current total must be 1.4 billion. We can also estimate that Apple sold about 303 million devices in 2018. This implies 2 out of 3 were replacements and 1 out of 3 increased the base.

Services revenues were about $40 billion in 2018 (up 28%). Total revenues were $261.5 billion.

Thus for the whole of 2018:

• $194 per active device of which...
• $30 in service revenues per active device

We can repeat the process for costs and earnings.

Through this lens, Apple's business over the last three years can be seen in the following graph:

A few observations:

• The business is remarkably stable over the last three years.
• The top line went from $179 to $165.
• The bottom line (Net margin) per device went from $55 to $51.
• This happened while the base multiplier went from 1.15 billion to 1.4 billion.
• Service revenues are increasing (from $24 to nearly $30)

Seen this way the pattern of service growth at the expense of hardware is clearly evident. This is generally contrary to perception when looking at devices sold per quarter.

This is a three year snapshot but if we were to forecast longer term, the questions that arise:

• How rapidly can the base multiplier rise? It had been rising at 150 million/yr for two years and 100 million for one year. What is the likely increase in the future? What is the saturation point? Is it 1.5 billion (which seems a year away) or is it 2 billion or more?
• How are services ramping? The revenue per device is ramping in an accelerated rate (from $2/yr/yr to $3/yr/yr). How high can revenue per device rise? Is $50/yr possible? Higher?
• Is the ASP increase reducing hardware revenues? This point is contentious and I will write about it separately.

It's going to take a while for this view of the company to prevail but it's clearly the way the company itself operates and how it sets its objectives.

In June of this year Apple reported that it had paid a total of $100 billion to developers. That is the 18th such figure given in the 10 year history of App Store, making the progress of payments and hence revenue and spending easily trackable.

The other regularly reported figure is the business segment revenue where App sales are currently allocated. Now called "Services" this omnibus segment includes many other sources of revenues such as:

• Digital Content (Books, Music downloads, Video downloads--including TV shows and movies and movie rentals.)
• AppleCare, Apple's extended warranty service.
• Apple Pay, transaction fees
• Apple Pro Apps, including Final Cut, Logic Pro, Motion, Aperture
• Licensing including "Made for iPhone/iPad"
• One-time settlements of various lawsuits.
• Other Services revenues which include
• Apple iCloud-related services
• Music Match
• Music subscriptions
• Other third party subscriptions (commissions)
• Third party licenses

This combined Services segment is significant with $35 billion revenues in the last 12 months. This is quite a jump from 2016 when Services had crossed $25 billion. At the end of 2016 Apple said it expected Services revenue to double by 2020. With a growth rate since then of 25% the company is on track to reach its target one year early. ((To calibrate this consider that Facebook revenues for the last 12 months were $48 billion and it now has a market capitalization of $468 billion or 41% that of Apple whereas Services consists of about 14% of Apple's total revenues.))

Consumer spending on Apple services includes more than what it books as revenue since only the (typically) 30% of App Revenues is considered Apple's revenue. Including the payments to developers, Services generated over $65.5 billion/yr in billings. This will reach $100 billion/yr in 2 years. The difference between reported revenues and consumer spending is shown in the following graphs.

I described the visibility into App Store revenues (which is the orange area in the graphs above) but the other sub-segments of Services are much more difficult to ascertain. Of special interest is Other Services which includes very high margin services. As part of that there is a peculiar source of revenues: Google.

It's known that Google pays Apple for the default placement of Google search within Safari on iOS and Mac OS. That payment is registered by Google as a "Traffic Acquisition Cost" or TAC. TAC is essentially payment for distribution where what is granted by the distributor is access to queries (traffic.) This way Apple acts as distributor for Google. So, for that matter, does Firefox which also receives TAC payments.

What is peculiar is that the amount of TAC paid by Google to Apple is becoming staggering.

A few years ago Google was paying over 20% of its revenues as TAC. Recently that ratio rose to 23%. Bernstein analyst Toni Sacconaghi estimated that Google paid Apple $1 billion in 2014 as TAC and that payments to Apple were about $3 billion in 2017. Now Goldman Sachs analyst Rod Hall estimates Google could pay Apple $9 billion in 2018, and $12 billion in 2019.

This is starting to look interesting but is it believable?

My own estimate of Apple's Other Services (which includes TAC revenues) is a run rate of $15 billion for calendar 2018. This makes $9 billion (60%) from Google quite challenging but not impossible. The remaining $6 billion needs to account for Apple's own cloud and subscription service revenues.

Does this make sense given Google's spending? TAC payments to distribution partners in Q2 were $3 billion. The $9 billion/yr assumption implies a $2.25B/quarter payment to Apple. That would be 75% of Google's distribution costs. That also sounds reasonable given the high utilization of iOS relative to any other platform.

An increase to $12 billion for next year is also quite a claim but it certainly is possible. I don't have a basis for making this estimate but the assumption of growth leads me to conclude that the payments are tied to actual traffic generated.

In other words the two companies have an agreement that Apple is paid in proportion to the actual query volume generated. This would extend the relationship from one of granting access for a number of users or devices to revenue sharing based on usage or consumption.

Effectively Apple would have "equity" in Google search sharing in the growth as well as decline in search volume.

The idea that Apple receives $1B/month of pure profit from Google may come as a shock. It would amount to 20% of Apple's net income and be an even bigger transfer of value out of Google. The shock comes from considering the previously antagonistic relationship between the companies.

The remarkable story here is how Apple has come to be such a good partner. Both Microsoft and Google now distribute a significant portion of their products through Apple. Apple is also a partner for enterprises such as Salesforce, IBM, and Cisco. In many ways Apple is the quintessential platform company: providing a collaborative environment for competitors as much as for agnostic third parties.

 

I think Lisa Jackson's presentation at the September 2018 iPhone launch event was perhaps the most interesting and most profound.

Lisa Jackson is Apple’s vice president of Environment, Policy and Social Initiatives. Previously, Ms. Jackson served as Administrator of the U.S. Environmental Protection Agency (EPA). In her role at Apple she has been responsible for the transition to 100% renewable energy use by Apple across all its facilities.

This goal has been achieved and it's a remarkable achievement deserving congratulations. But her presentation was noteworthy for setting a new goal.

She laid out a goal for Apple to eliminate the need to mine new materials from the Earth.

She said that to reach that goal Apple will have to do three things:

1. Sourcing recycled or renewable materials for all products.
2. Ensure that Apple products last as long as possible.
3. After a long life of use, ensure that they are recycled properly.

It's this second point that I thought would bring the house down.

To emphasize the second point she said Apple now strives to design and build durable products that last as long as possible. That means long-lasting hardware coupled with long-lasting software. She pointed out that iOS 12 runs even on iPhone 5S, now five years old. Because iPhones last longer, you can keep using them or pass them on to someone who will continue to use them after you upgrade.

She said that "keeping iPhones in use" is the best thing for the planet.

At this point in the presentation I wondered if everyone would rush out of the room and call their broker to sell Apple shares. One premise of investing in durable goods hardware companies is that value depends on frequency of upgrades. If products are not replaced frequently they do not generate revenues and the company selling them ends up growing very slowly if at all after markets saturate. The smartphone business is certainly approaching saturation and the implication of making Apple products more durable would imply lower revenues from replacements. This anxiety around replacement rates and extended lives is used by analysts to discount future cash flows and if those lifespans are extended price targets come down.

So why would Apple want to do this?  What is the logic of this durability focus as a business model? It may be good for the environment but is it good for the bottom line?

Of course, there would be not much business without an environment and we should all strive for sustainability.  But this is an existential observation, and it's defensive. The important call to make is that Apple is making a bet that sustainability is a growth business.

Fundamentally, Apple is betting on having customers not selling them products.

The purpose of Apple as a firm is to create and preserve customers and to create and preserve products. This is fundamental and not fully recognized.

To understand how this works, if you look at the pricing graph below, you can read it as a story of increasing prices for a decreasing market share. But if you understand that each advance in products increases absorbable ((Insoluble  utility is very dangerous and it's important to qualify e.g. higher storage capacity that people hunger for or better cameras that increase picture taking from features that are neat but don't get utilized)) utility then the cost per use remains steady or declines.

An iPhone at $1200 may be less expensive than an iPhone at $600 if the $1200 version lasts twice as long as is used twice as much each day. The $1200 phone delivers 4x the utility at twice the price, making it half the price. By making more durable products, both in terms of hardware and software, the customer base is satisfied and preserved.

Practically, the initial buyer may resell the iPhone and that 2nd hand devices may be sold yet again. This means an iPhone could have three users over its life and thus it could end up expanding the audience for Apple by a factor of 2 or even 3.

The expanded audience is offered accessories, additional products such as wearables and, of course, services. These residual business models are certainly profitable, perhaps even more so than the iPhone.

Overall Apple has 1.3 billion devices in use and perhaps as many as 1 billion users. This base is certain to expand and it will expand more rapidly with durable devices and software.

This is a hardware-as-platform and hardware-as-subscription model that no other hardware company can match. It is not only highly responsible but it's highly defensible and therefore a great business. Planned obsolescence is a bad business and is not defensible.

Therefore the statement that Apple now prioritizes device and software longevity is very important and I consider it one of the most important statements made during the 2018 iPhone launch event.

Every October, at the end of its fiscal year, Apple files its Form 10K or annual report. In this report the company includes a section titled "Capital Assets" which details expenditures for capital equipment. This is last year's entry:

The Company’s capital expenditures were $14.9 billion during 2017. The Company anticipates utilizing approximately $16.0 billion for capital expenditures during 2018, which includes product tooling and manufacturing process equipment; data centers; corporate facilities and infrastructure, including information systems hardware, software and enhancements; and retail store facilities.

Note that there are categories of spending detailed and that their order might indicate the degree of such spending, suggesting that product tooling and manufacturing equipment is likely to be the costliest category.

After this report, during subsequent quarters the company may update this forecast of spending. In the last (third fiscal) quarter the entry was as follows:

The Company’s capital expenditures were $11.1 billion during the first nine months of 2018 . The Company anticipates utilizing approximately $17.0 billion for capital expenditures during 2018, which includes product tooling and manufacturing process equipment; data centers; corporate facilities and infrastructure, including information systems hardware, software and enhancements; and retail store facilities.

Note that the forecast of $16.0 billion was updated to $17.0 billion and the first 9 months' expenditures were $11.1. Since there is only one quarter remaining ((and since at the time the quarterly report is filed, only about 2 months remain in the quarter)) it's reasonable to assume that the company's forecasts are more likely to be precise and that therefore the difference between total expected spending and already spent, i.e.f $5.9 billion remains to be spent.

The actual spending is not recorded quarterly but an approximate value is reported in the Cash Flow statement as "Payments for acquisition of property, plant and equipment". That can be tracked but it does not equal exactly the capital expenditure. For example, the quote above says expenditures were $11.1 billion through first 9 months but the total of all payments for acquisition of PP&E is $10.272 billion.

Minor ((To the extent that $1 billion can be considered minor)) differences, aside, this forecast and actual spending and payments data is significant because it is highly correlated to Apple's overall business. Assuming that the spending on manufacturing equipment and information systems hardware (i.e. data centers) is in support of the iOS device sales and services we can try to show how sales correspond to spending with the following graph:

Here sales are shown as a bar graph and the various spending forecasts and actual payments are shown as lines. Also note that the spending and sales are offset by one quarter. The fiscal year is used for spending and the calendar year for sales. The reason is that spending is presumed to lead sales by approximately one quarter.

There are some notable discrepancies, especially with the 2012/2013 period when spending was brought forward a quarter thus showing a surplus to forecast in 2012 and a deficit in 2013. But apart from that, there is a broad correlation between spending and sales.

This means that the CapEx forecast in October is a good indicator of sales in the following year.

In fact, the relationship is can be shown with four scatter plots, one for each of the published figure:

I caution that this is a yearly forecast and it is revised through the year on a quarterly basis, sometimes up, sometimes down. It's therefore not a perfect indicator and of course the relationship between sales and spending is not perfectly predictable. Note that there are four types of spending that can be measured, two are forecasts (one year and revised) and two are actuals (cash flow payments and reported total expenditures)

We can measure the best variable that fits the sales data through the coefficient of determination or R-squared. The best fit seems to be with Payments for acquisition of property, plant and equipment (R-squared of 0.976).

This gives the formula for yearly sales as 15.915x + 15809 where x is the expected total spending. That spending to date has been $10.272 billion and it's probably going to exceed $16 billion for the year.

Using $16 billion spending total, we can calculate iOS products and services for calendar 2018 of $270.45 billion.

iOS and Services sales to date have been $103.2 billion with an estimate for next quarter of about 54.3 billion (based on guidance) and thus a total through Q3 of $157.5 billion. Subtracting this from the $270.45 billion expectation from the calculation above gives a fourth calendar quarter iOS revenue of $113 billion.

Adding $7 billion for the Mac results in a total net sales of 120billion. This therefore is what I'd put forward as a reasonable target for CQ4.

Note that this is equivalent to a growth of 36% from the 2017 fourth quarter.

[UPDATE: Original version used total sales rather than iOS related products and services (i.e. excluding Mac). The text has been edited to reflect the correct figures.]

Three months ago Apple provided the following guidance:

As we move ahead into the June quarter,[…] We expect revenue to be between $51.5 billion and $53.5 billion. We expect gross margin to be between 38% and 38.5%. We expect OpEx to be between $7.7 billion and $7.8 billion. We expect OI&E to be about $400 million. And we expect our tax rate to be about 14.5%.

If we aim for a revenue figure close to the upper end of the range ($53.2 billion) and insert all the other figures (split the difference for OpEx) then then the company's fiscal third quarter looks as follows:

Revenues: $53.2b
iPhone (units): 43.2 million
iPad (units): 11.6 million
Mac (units): 4.3 million
Services ($): 9.5 billion
Other products ($): 3.5 billion
Gross margin (%): 38.6%

EPS ($): $2.26

This last figure, the earnings per share, is the most speculative because it depends on another guidance that Apple gave: a new $100 billion share repurchase authorization and the fact that it has no time frame. For context, as of end of March the company had completed over $275 billion of its previous $300 billion capital return program and $10 billion remained for share re-purchases in the June quarter. It's unclear how much of the new authorization will be spent in the quarter.

That spending could indicate the share count but there are issues with this calculation as well. The $2.26 EPS I forecast is based on the assumption that the the same number of shares will be retired as in the previous quarter (about 89 million shares.) However the company spent $23.5 billion on repurchases of 137 million Apple shares through open market transactions (for an average price or $171.53, in-line with the quarter's trading average).

So why is the number of shares purchased (137 million) so different from the change in shares used to compute earnings per share (89 million)? I actually don't know.

The question of how many shares are available to calculating EPS is perhaps the last mystery in what is otherwise a very predictable business. The revenue growth and implied iPhone growth are pretty transparent. Incidentally, the EPS I'm forecasting is equivalent to growth of 35.8% y/y. The share price is trading at multiples about half of this growth rate so it's no wonder the company is spending most of the cash on re-purchases.

How quickly the $100 billion re-purchasing authorization will be used is another question. The effect in concentration of value per share could be profound as shown in the graph above which will have further implications on the "cash zero" direction for the company.

 

 

At the latest Apple Summit in Los Angeles the question of Apple's valuation was foremost on many minds. The illustration I used there to discuss valuation is shown below.

It shows the history of revenues (by reported segments) and gross margin for the five largest companies in the world by market capitalization. I have been publishing this illustration for five years ((initially with Samsung rather than Facebook because it was originally a set of "challengers" to Apple. The fact that with only one substitution the illustration turned into a view of the five largest companies in the world was a welcome surprise.)) in order to contrast the growth and perception of value between companies that might be considered comparable with Apple. Thus the graphs show the top and (near) bottom lines of the companies over an epoch of about a decade. ((This being the iPhone epoch))

In contrast with the histories above, there is a price set on the equities today. These prices are captured by the market capitalizations as follows:

	Current market cap (billion)	Peak market capitalization (Billion)
Apple	$918	$955
Amazon	$844	$856
Alphabet	$810	$825
Microsoft	$780	$789
Facebook	$584	$589

 

Market capitalizations are interesting because they show perceptions of value. The traders in the equity are negotiating with each other on what the shares are worth and, as a voting system in a liquid public asset, share pricing is very representative of the perceptions about that asset. Representative because there are literally millions of decisions being made on a daily basis which determine this price.

The sales and profit data in the illustration above is about the past. In contrast the market engine is voting about the future. Any student of finance knows: the value of a company is the net present value of all future discounted cash flows (plus any current assets.)

So what would history have to do with it? What use is the trajectory?

This goes to a deeper question: How does history inform the future? What is the value in knowing previous performance when thinking about future performance? The common caveat in mutual fund prospectuses is "Past performance is no guarantee of future results". We are repeatedly warned of this because it is within our nature to look at history and recognize patterns. But beware! At least beware those whom you might entrust with your fortune.

But consider that it's conventional wisdom to also say that culture and preparation are the best ways to ensure a prosperous future. Ask athletes or coaches and they will say that practice and dedication lead to success.  Sports fans know that a team or player with a record of success is more likely to succeed in the future. In this way sport is, in many ways, a simulation of reality. Which is why it's so popular: a metaphor of life teaches as well as entertains.

Knowing how to read ability as well as conscientiousness are keys to scouting talent. Again, it's not a guarantee, but in various fields of human endeavor the past does predict, with high accuracy, the future.

This relationship between past and future is what education is based on. We spend our lives preparing and training ourselves and our children and their children with the implicit hope that this leads to better outcomes for everyone. We establish a pattern of success because it is the best predictor of future success. Practice, learn, commit, defer satisfaction, trade time for knowledge, fight, lose and try again. These are the qualities we look for in the past of individuals when assessing their potential for the future. Culture is everything, we are told. Build a track record, we tell the young.

So what does this have to do with valuation?

We can't easily measure the cultures of persistence and perseverance in companies. Grit, guts, stoicism, fortitude, courage, the Finnish "sisu". These are not measurable in financial reports. Yet our language is as filled with words to describe character and our financial reports are empty of them.

It's left to investors to work it out. The exercise of relating the future to the past is the calculation of the ratio between Price (future) and Earnings (past). A high P/E ratio suggests repeated success from past success. A low P/E is a disbelief in a future repeating the past.

The P/E ratio thus allows us to say to what degree recent past performance is repeatable. I.e. how many `last years' can we expect in the future. A P/E of 1 means a company is worth what it earned last year. A P/E of 10 means it is worth ten years' proceeds. ((We could easily calculate P/E for more than one year but the default is one year.))

This P/E ratio is shown for the five companies above as the overlaid bars in the graph above.

Sure, you say, but it depends on the industry and circumstances. A future divorced of the past is more likely in an environment where there is rapid, chaotic change. The more volatility in fundamentals, the more uncertainty. Technology is changing rapidly and therefore it's quite possible that Apple's low P/E reflects this disconnect.

If so then what about its peers? Why would Apple be subject to different technological risk than other technology companies? All of the top five companies are considered "tech". Indeed, Apple is perhaps the least technologically oriented as it has a brand and consumer orientation. It operates hundreds of stores, and sells design as much as it sells algorithms. It fundamentally tries to deconstruct human needs and package those needs in products.

Alphabet, Microsoft and Facebook primarily don't "sell" to end-users. The revenues come from businesses in the form of advertising or licensing. They don't have support staff, interacting with people who buy what they use. They need to understand needs but they trade other things. And Amazon offers AWS to enterprises as its own unique product. Other than AWS it operates a marketplace, acting as an intermediary.

Apple is a consumer company depending on consumer tastes as a brand. This is more typical of a non-tech company in a boring business of consumer brands.

But it's not valued as either a tech company or a consumer company. Both have typically higher P/E ratios. In fact, Apple's P/E ratio is lower than the S&P 500 and has been below that level for almost the entire history of the iPhone, regardless of growth rate.

A track record of hit products and the stability of a brand seem to be of no value. Perseverance, consistency and stability are not valued. If it were an athlete with a track record of world-record performance and a spectacular reputation with the public, it would not be granted an above-average pay for its performance.

In the past I've argued anti-fragility as a cause. In the context of the other companies, Apple is at the center of perceived vulnerabilities and is thus perceived as vulnerable . The other four are at the center of no competition and perceived as invulnerable. And yet Apple, so far, has survived. So have the others, but apart from Microsoft, they are much younger. I argued that Apple exhibits anti-fragility and has unrecognized robustness. Perhaps Warren Buffet now agrees and this is encouraging to the thesis.

Yet, at an even deeper level, in Apple's valuation we see how culture is not valued. How the idea of character assessment is not applied to businesses. How ethos is unquantifiable and thus discounted. How markets, accustomed to weighing things, reflective of collective human judgement, demonstrate that we are woefully incapable of valuing that which matters most.

Oscar Wilde famously said that the cynic knows the price of everything and the value of nothing. Here's to the sentimentalist, because at the end of the day those who change the world know the value of everything and the price of nothing.

The iMac launched May 6 1998, exactly 20 years ago. It is not the most significant computer to ever exist. It was a clear descendant of the original Mac which established the "all-in-one" desktop computer category. That category, to which it still belongs, is a modest segment. The last time Apple reported portable sales separately was in late 2012 when the desktops/servers and pro systems combined made up only 20% of all Mac sales by units. If iMac were 10% of Mac sales, it would represent about 2 million units in 2017.

Desktops evolved into laptops and personal computing evolved into pocket  computing. Becoming more personal means more intimacy and this is leading to wearable computing. There is more beyond that to be sure.

But the iMac is a historically significant machine. It allowed Apple to start on a new trajectory. It did this by first offering a financial lifeline. Sales of Macs, which were at the time the only source of revenues for Apple, increased from 2.7 million to 3.8 million a year. This at a time when Windows PCs were shipping about 100 million units. That was enough to ensure survival. Today Mac units are five times higher while Windows PCs are about 2.5 times higher. The following graph shows the impact of iMac on the Mac's trajectory. 

Second, the iMac was the first host of OS X, an operating system built on Unix which made it extremely flexible. iMac gave Apple the space for OS X to be developed and to be optimized for various hardware. The experience with OS X and its inherent scaleability (down as well as up) meant that it could be considered for the post-PC devices of the future.

Lastly, iMac's design screamed "consumer product" which went from signaling inferiority to superiority. It set a standard for novelty, creativity and dynamism in the category that was considered second-rate. In the early 2000s consumers began to lead in the adoption of new technologies. DVD drives, internet connectivity, wifi, instant messaging, media consumption exploded. All the while institutions, hung up on legacy, began to block technologies. At this pivotal moment, the iMac spoke with its looks. It didn't just imply a new order, it stated it.

To me the incredible aspect of the iMac's entry is its uncanny timing. It came not only just in time to save Apple but exactly half-way between the first two ages of computing. In the following graph showing "share of computing" you can see it as launching precisely at "peak Windows".

In retrospect you have to wonder if Apple, with the iMac, was lucky to survive into this next era or if that era would have ever happened without the iMac. It's a question of causality which quickly devolves into an un-winnable argument about stochastic vs. deterministic existence.

Regardless, the result was felt more than seen. The computing industry was pivoting. The results are seen also in the graphs above. The iMac came right in the middle of the "desert" of platform choice of the late 1990s. By the 2000s mobile platforms detonated on the scene. The iPod was Apple's first entry, in 2001, but it was not a computer. It was an appliance. A stepping stone at a time when the early platform contenders Nokia, Palm, Microsoft and BlackBerry surged before realizing that they did not have sound foundations upon which to build ecosystems. Their advances could not be consolidated.

The spoils went to the later entries of iOS and Android. The resulting disruption was shocking and disorienting. Not only did the old order get up-ended but the magnitude of the new was 100x the old. The iMac enabled at least a trillion dollars of value to be created and made Apple the biggest company in the world.

As you would expect, at the time, 20 years ago, none of this change was anticipated. iMac was a 'cute' computer. Toy-like and obviously unprofessional. It attracted and relished contempt.

So now we are at a point where the second era of computing is at its apex. With markets near saturation, the device business is inflecting from growth to possible stagnation if not decline. There are two platforms--though unlike Windows, Android is fragmented and iOS is not just on one form factor. Nevertheless there is stasis. The touch UI which begat nine billion devices is normative. The next interaction metaphor has not emerged as an obvious successor.

The question for today is what is the new iMac? What is the enabler for change? It's not easy to spot. It is not the thing of the future but it points to the future.

The following is a transcript of the comments from Tim Cook (CEO) and Luca Maestri (CFO) at Apple's Q1 2018 Earnings Conference Call February 1, 2018. I color coded my interpretation of the comments into four categories:

• Grey: Background and promotional commentary
• Red: Strategy and signals of what management considers important and may include data beyond the regularly reported numbers.
• Green: Financial data
• Black: Commentary.
• Blue: My commentary, in brackets.

For a quick read of Apple's strategy, read the Red text. These comments are not repeated in financial reports. Highly recommended.

For a quick read of Apple's financial performance, read the green text (which are replicated in financial reports). Read this if you don't want to wade through the financial reports.

For marketing or product material, read the grey text.This is sometimes unique but also repeats product launch information.

Tim Cook:  Thanks, Nancy and thanks everyone on the call, and welcome to everyone today. Before we dive into the quarter, I'd like to take a moment to talk about a significant milestone we recently crossed.

Apple's active installed base reached 1.3 billion devices in January and is at an all-time high for all of our major products. 1.3 billion devices represents an astonishing 30% growth in just two years. It speaks to the strength and reliability of our products and our ecosystem, as well as the loyalty, satisfaction and engagement of our customers. It's also fueling tremendous growth in our services business, which I’ll talk about a little later in the call. [This is probably Apple's most important number. For at least the next 20 years this is the key performance metric and it can be used to derive company's valuation. A summary of the history of active devices vs. units sold is shown in the graph below:]

Turning to the December quarter. We're thrilled to report Apple's biggest quarter ever, which set new all-time records in both revenue and earnings. We generated revenue of $88.3 billion, which is above the high-end of our guidance range, and it is up almost $10 billion or 13% over the previous all-time record we set a year ago.

It's also our fifth consecutive quarter of accelerating revenue growth with double digit growth in each of our geographic segments around the world. What makes us even more remarkable is that the quarter we're reporting today was 13-weeks long, while the year ago quarter was 14-weeks. When we look at the average revenue per week in the December quarter this year compared to last year, our growth was a stunning 21%. [The 13-week vs. 14-week year-on-year comparison is repeated several times. The summary differences are shown in the table below:] 

Our growth was broad-based and a key driver was iPhone, which generated its highest revenue ever. iPhone X was the best-selling smartphone in the world in the December quarter according to Canalys, and it has been our top selling phone every week since it launched. iPhone 8 and iPhone 8 Plus rounded out the top three iPhones in the quarter. In fact, revenue for our newly launched iPhones was the highest of any lineup in our history, driving total Apple revenue above our guidance range. [The iPhone X is a huge hit. It drove the average selling price $100 higher y/y. This is not only unprecedented for Apple but for the entire Industry. The average smartphone sells for less than $300 while iPhones sold for $800. The gap is widening. The following graph shows the product mix and the average resulting price.] 

I want to take a moment to recognize the tremendous amount of work that went into creating iPhone 10. Our teams carried out an extremely complex launch from both an engineering and operations perspective, executing an outstanding product ramp that required years of research and development; one that introduced innovative features like an edge-to-edge Super Retina Display and the TrueDepth Camera, which enables face ID. Our customers love these new features and the new gestures like simply swiping up from the bottom, which make using iPhone even more intuitive and enjoyable.

Our team has put the technology of tomorrow in our customers’ hands today, set a standard for the next decade of smartphones and we are very proud of their achievements.

It was another very strong quarter for services with revenue of $8.5 billion, up 18% over last year, and we’re on pace to achieve our goal of doubling our 2016 services revenue by 2020. The number of paid subscriptions across our services offerings passed 240 million by the end of the December quarter, that’s an increase of 30 million in the last 90 days alone, which is the largest quarterly growth ever. [Services has been growing relentlessly for over a decade. This steadiness of growth makes is a juggernaut. Apple is increasingly speaking about subscriptions as the key metric and 240 million is reaching record territory. The rise of Services is shown below (both revenues and consumer spending.)]

We had an all-time record quarter for the App Store with our best holiday season ever. We’re seeing great excitement around augmented reality with customers now enjoying over 2,000 ARKit enabled app, spanning every category in the App Store. In December, when Pokémon GO released its new augmented reality features built with ARKit, it jumped the top of the App Store charts. Last week, on a stop in Toronto, I met developers who are hard at work on creative applications using ARKit from art appreciation to ecommerce, and I was very impressed with what I saw.

Just for months after ARKit launched to the public, we’ve already released ARKit 1.5 in beta to developers around the world, and the response has been tremendous. Augmented reality is going to revolutionize many of the experiences we have with mobile devices. And with ARKit, we’re giving developers the most advanced tools on the market to create apps for the most advanced operating system running on the most advanced hardware. This is something only Apple can do.

In addition to the App Store, several other services had their biggest quarter ever, including Apple Music, iCloud and Apple Pay, all of which saw growth in both active users and revenue.

Apple Pay has reached an important milestone in the U.S. As a result of 50% year-over-year growth in merchant adoption, it’s now accepted at more than half of all American retail locations, which includes more than two-thirds of the country’s top 100 retailers. Now available in 20 markets, global Apple Pay purchase volume more than tripled year-over-year and we’re delighted to be expanding to Brazil in the coming months. [There are no absolute data points on Apple Pay but we do have some scattered growth data. The US data is cited here but in my experience it's more popular in select countries like UK where users are using it habitually]

Today, you can use Apple Pay to take the subway in Guangzhou, China, see a concert at London’s Wembley Stadium or buy a souvenir in Yosemite National Park. In the U.S., we launched Apple Pay Cash in December, and it’s off to a terrific start. Millions of people are already using it to send and receive money with friends and family quickly, easily and securely; to split a bill, pay someone back, or send last minute gift right from the messages app.

It was our best quarter ever for the Apple Watch with over 50% growth in revenue and units for the fourth quarter in a row and strong double-digit growth in every geographic segment. Sales of Apple Watch Series 3 models were also more than twice the volume of Series 2 a year ago. Apple Watch is the most popular, smart watch in the world and gained market share during the quarter based on the latest estimates from IDC. [Apple Watch is growing consistently. The following graph shows my estimates of volume (total 42 million to date) and revenues (total $15 billion) based on all available data and commentary from management.]

It was the third consecutive quarter of growth for iPad revenue, thanks to the strength of both iPad and iPad Pro. Based on the latest data from IDC, we gained share in nearly every market we track with strong outperformance in emerging markets.

Worldwide, almost half of our iPad sales were the first-time tablet buyers are those switching to Apple, and that’s true in some of our most developed markets, including Japan and France. In China, new and switching users made up over 70% of all iPad sales.

For Mac, we launched the all new, iMac Pro in mid-December. It’s an entirely new product line designed for our Pro users who love the all-in-one design of iMac and require workstation class performance. It's the fastest, most powerful Mac ever, delivering incredible computational power, for simulation and real time 3D rendering, immersive VR and complex photography audio and video projects. Worldwide, 60% of our Mac sales were the first time buyers and switchers and in China, that number was almost 90%.

We're looking forward to getting HomePod in customers’ hands beginning next week. HomePod is an innovative wireless speaker, which delivers stunning audio quality wherever its placed in the home, thanks to the advanced Apple engineered hardware and software.

Together with Apple Music, HomePod gives you instant access to one of the world's largest music catalogs. And with the intelligence of Siri, it’s a powerful assistant you control through natural voice interaction. We're very happy with the initial response from reviewers who've experienced HomePod ahead of its launch, and we think our customers are going to love this new product.

We believe one of the key issues of the 21st century is education. And because of that, we've strengthened our commitment and investment into initiatives like everyone can code. To find the innovators of the future, we need to nurture the students of today. Our App Development with Swift curriculum, which is available free on iBooks, has been downloaded more than 1.2 million times worldwide with almost half of those coming from here in the United States. It’s also being taught in dozens of community colleges across the country, putting practical skills in the hands of today’s jobs seekers.

I was in London two weeks ago as we announced that the program was expanding to more than 70 colleges and universities in Europe. Millions of students around the world will have the opportunity to add Swift to their coding vocabulary and gain skills that are essential for today’s economy.

This is an exciting time at Apple and with the best lineup of products and services we've ever had and a set of initiatives that show how business can be a force for good in the world. We could not be more excited about our future.

Now, for more details on the December quarter results, I'd like to turn over the call to Luca.

Luca Maestri: Thank you, Tim. Good afternoon, everyone. Our business and financial performance in the December quarter were exceptional, as we set new all-time records for revenue, operating income, net income and earnings per share.

Starting with revenue, we’re reporting an all-time record, $88.3 billion, up nearly $10 billion or 13% over the prior record set last year. It is our fifth consecutive quarter of accelerating revenue growth. As you know, the December quarter a year ago spanned 14-weeks compared to 13-weeks this year, which is important to consider as we have set the underlying performance of our business this year. When we look at average revenue per week, our growth rate was even higher at 21% with growth across all product categories for the third consecutive quarter.

Our results were terrific all around the world with double digit revenue growth in all our geographic segments, an all-time quarterly record in the vast majority of markets we track, including the U.S., Western Europe, Japan, Canada, Australia and Korea, as well as Mainland China, Latin America, The Middle East, Central and Eastern Europe, and India.

In Greater China, we were very happy to generate double digit revenue growth for the second quarter in a row and in emerging markets outside of Greater China, we saw 25% year-over-year growth.

Gross margin was 38.4% at the high end of our guidance range. Operating margin was 29.8% of revenue. Our net income was $20.1 billion an all-time record, and up $2.2 billion over the last year. Diluted earnings per share were $3.89 also an all-time record and cash flow from operations was very strong at $28.3 billion.

During the quarter, we sold 77.3 million iPhones, the highest number ever for a 13-week quarter. Average weekly iPhone sales were up 6% compared to December quarter last year with growth in every region of the world despite the staggered launch of iPhone 10. We established all-time iPhone revenue record in nearly every market we track with double-digit growth in all of our geographic segments. iPhone ASP increased to $796 from $695 a year ago, driven primarily by the launch of iPhone 10 and the success of iPhone 8 and 8 Plus.

We exited the December quarter towards the lower end of our target range of five to seven weeks of iPhone channel inventory with less than 1 million more iPhones in the channel compared to the December quarter a year ago, in line with our growth in average weekly unit sales. Customer interest and satisfaction with iPhone are very, very strong for both consumers and business users.

The latest data from 451 Research indicates U.S. customer satisfaction ratings of 96% or higher across iPhone models. In fact, combining iPhone 8, iPhone 8 Plus and iPhone 10, consumers reported an amazing 99% satisfaction rating. And among business customers planning to purchase smartphones in the next quarter, 77% planned to purchase iPhone. Our customers are also incredibly loyal with Kantar's latest U.S. research, reflecting a 96% iPhone loyalty rate, the highest ever measured. [Customer satisfaction is the second most important figure after active user base. Combining these two figures yields the recurring revenue value of the company. Remember what Deming said: the most important measurements for a company's value are the multipliers of a satisfied customer and a dissatisfied customer--these numbers never appear on any financial report but they are applied to all the numbers on every report].

Turning to services. We had a terrific quarter with revenue of $8.5 billion, up 18% year-over-year and up 27% in terms of average revenue per week; that is an acceleration to the 24% services growth run rate that we experienced in the September quarter.

The App Store set a new all-time revenue record. The Store’s all-new design is off to a fantastic start with quarterly store visitors, transacting accounts and paying accounts, reaching new all-time highs. During the week beginning December 24th, a record number of customers made purchases or downloaded Apps from the App Store, spending over $890 million in that seven-day period, followed by $300 million in purchases on New Year’s day alone.

And according to App Annie’s latest report, the App Store continues to be the preferred destination for customer purchases by a very wide margin, generating nearly twice the revenue of Google Play. Across all our services offerings, paid subscriptions reached $240 million with growth of 58% over last year and they were a major contributor to the overall strong growth in services revenue. [Apple has half the user base of Google Android. This is based on Google's May 2017 report of 2 billion active devices vs. the 1.3 billion that we just got from Apple. And yet these users collectively spend twice as much on apps. This ratio of "half the users, twice the spending" has been cropping up in individual developer anecdotes and can also be seen in other metrics of engagement and consumption. This should not be surprising as it conforms to the Pareto distribution of economic value.]

As Tim mentioned, it was our best quarter ever for Apple Watch. And when we add to this us from Beats and AirPods, our total revenue from wearables was up almost 70% year-over-year. In fact, wearables were the second largest contributor to revenue growth after iPhone, which is impressive for a business that started only three years ago. In total, our other products category set a new all-time record with quarterly revenue exceeding $5 billion for the first time. [Wearables now includes more than watches but watches are likely still the dominant product.]

Next, I’d like to talk about the Mac. We sold 5.1 million Macs during the December quarter, which translates to a 2% year-over-year increase in average sales per week. Mac performance was particularly strong in emerging markets with unit sales up 13% year-over-year and with all-time records in Latin America, in India, Turkey and Central and Eastern Europe. On a worldwide basis, the active install base of Macs was up double-digits year-over-year to a new record.

It was also another growth quarter for iPad. We sold 13.2 million units with average iPad sales per week up 8% over last year’s December quarter. iPad sales grew strong double-digits in many emerging markets, including Latin America, the Middle East, Central and Eastern Europe and India, as well as developed markets, including Japan, Australia and Korea. The active install base of iPad has grown every quarter since its launch in 2010, and it reached a new all-time high in December, thanks to extremely high customer loyalty and large numbers of first-time iPad users. [iPad is clearly recovering from a long decline. ASPs are rising as it's being positioned as a PC alternative. Its low end functions are being absorbed by large screen iPhones.]

NPD indicates that iPad had 46% share of the U.S. tablet market in the December quarter, up from 36% share a year ago. And the most recent surveys from 451 Research found that among customers planning to purchase tablets within 90 days, 72% of consumers and 68% of business users planned to purchase iPads. Customer satisfaction is also very high with businesses reporting a 99% satisfaction rating for iPad.

We are seeing great traction in enterprise as businesses across industries and around the world standardize on iOS. For example, Intesa Sanpaolo, one of Europe’s leading banks, has chosen iOS as the mobile standard for its entire 70,000 employee base in Italy; choosing iOS for its security, user interface, accessibility and reliability, Intesa Sanpaolo will deploy native apps to improve employee productivity in customer support, human resources, and marketing across the company.

And LensCrafters, one of the largest optical retail brands in North America, will be using over 7,000 iPad Pros to enable digital eye exams and digital optical measurements in a personalized and interactive experience. We’re also rolling out a new initiative, called Apple AtWork to help businesses implement employee choice programs more easily and offer Apple products company-wide.

Resources from both Apple and our channel partners will enable enterprise IT and procurement teams to buy or lease Apple products more efficiently, streamline the setup of iPhone, iPad, and Mac, and deliver a seamless onboarding experience for employees. We launched the program with CDW in the U.S. last week, and we would be expanding to more channels and regions later this year.

The December quarter was extremely busy for our retail and online stores, which welcomed 538 million visitors. Traffic was particularly strong during the four-weeks following the launch of iPhone 10, up 46% over last year. And across the quarter, our stores conducted over 200,000 today at Apple sessions, covering topics including photography, music, gaming, and app development, and art and design. Just last weekend, we opened our first store in Seoul, Korea and we’re looking forward to opening our first store in Austria in a few weeks. These newest openings will mark the expansion of our retail store presence to 21 countries.

Let me now turn to our cash position. We ended the quarter with $285.1 billion in cash plus marketable securities, a sequential increase of $16.2 billion. $269 billion of this cash, or 94% of the total, was outside the United States. We issued $7 billion in debt during the quarter, bringing us to $110 billion in term-debt and $12 billion in commercial paper outstanding, for a total net cash position of $163 billion at the end of the quarter. We also returned $14.5 billion to investors during the quarter. We paid $3.3 billion in dividends and equivalents, and spent $5.1 billion on repurchases of 30.2 million Apple shares through open market transactions.

We launched a new $5 billion ASR program, resulting in initial delivery and retirement of 23.6 million shares and we retired 3.8 million shares upon the completion of our 12th ASR during the quarter. We’ve now completed over $248 billion of our $300 billion capital return program, including $176 billion in share repurchases against our announced $210 billion buyback program with $34 billion remaining under our current authorization. [An updated look at Apple's cash is shown below]

Turning to taxes. Due to the recently enacted legislation in the U.S., we estimate making a corporate income tax payment of approximately $38 billion to the U.S. government on our cumulative past foreign earnings. This amount is very similar to what we had been accruing on those earnings in our financial results through fiscal year 2017, including the $38 billion payment. We will have paid over $110 billion of corporate income tax on our total domestic and foreign earnings during the last 10 years for a cash tax rate of about 26%. [Apple has paid more tax than any company in history, and is about the make the largest single payment to the US Treasury.]

Our tax rate of 25.8% for the December quarter was close to our guidance of 25.5% as the lower U.S. statutory rate from the new legislation was effective offset by the remeasurement of deferred tax balances.

As we move ahead into the March quarter, I'd like to review our outlook, which includes the types of forward looking information that Nancy referred to at the beginning of the call; we expect revenue to be between $60 billion and $62 billion; we expect gross margin to be between 38% and 38.5%; we expect OpEx to be between $7.6 billion and $7.7 billion; we expect OI&E to be about $300 million; and we expect the tax rate to be about 15%.

Tax reform will allow us to pursue a more optimal capital structure for our company. Our current net cash position is $163 billion. And given the increased financial and operational flexibility from the access to our foreign cash, we are targeting to become approximately net cash neutral overtime. We will provide an update to our specific capital allocation plans when we report results for our second fiscal quarter, consistent with the timing of updates that we have provided in the past.

Finally, today our Board of Directors has declared a cash dividend of $0.63 per share of common stock, payable on February 15, 2018, to shareholders of record as of February 12, 2018.

In its latest update on the App Store Apple reported that iOS developers earned $26.5 billion in 2017. A year ago the figure was $20 billion. The growth rate is then about 33%. The cumulative payments to developers can be calculated as $86.5 billion. This amount was generated in a span of less than 10 years, with the first billion paid by June 2010.

The following graph shows the history of cumulative payments and the corresponding payment rate (in $/yr.)

Note that this represents the payment to developers, not the spending by the customer. Apple keeps about 30% of the revenue.  The total spending on the App Store is then about 43% higher. ((During the last year some types of app subscriptions have been priced by Apple at 15% of gross so I adjusted the payment rate to 72% for 2017)). The equivalent figures for spending on the App Store are shown below.

A few observations:

• Developer payment rate is now above $25 billion/yr. I've been notified via Twitter that this is higher than the revenue of McDonald's Corporation in 2016.
• During this year iOS users will be spending about $100 million per day for Apps. This was Google's AdWords revenue rate in 2012.
• The spending on App Store has been rising steadily, adding about $5 billion/yr since mid 2011.
• Apps are the biggest component of Apple services and helped that segment gross over $57 billion in 2017, passing Fortune 100 level (net of developer payments).

I've made comparisons before with the app business being bigger than the film industry (and much bigger than the music industry.) This was considering Android revenues and iOS combined as "app revenues".

As of this year the App Store alone will overtake Global Box Office revenues.

Of course this is only an observation of the scale of App Store rather than a judgement of the benefit obtained from either medium or the substitutability of one for the other. ((The substitutability of apps for movies is not to be discounted either. The analysis should be based on understanding the jobs the media are hired to do.)) The reason scale should be noted is that the App Store, and Apple services overall, is becoming one of the largest enterprises in the world. Even more importantly, it should be noted for its rate of growth.

Even when considering this, one should keep in mind that the figures of revenue and payments to developers are only a small fraction of the overall app economy. Apps sold to end users are a subset of all apps on the App Store. There are not only free apps but also many apps which are front-ends to complex services which are monetized in various indirect ways.

Facebook, Twitter, Linkedin, Tencent, YouTube, Pandora, Netflix, Google, Baidu, Instagram, Amazon, eBay, JD.com, Alibaba, Expedia, Tripadvisor, Salesforce, Uber, AirBnB and hundreds of others are all "free" apps enabling hundreds of billions of dollars of interaction none of which are captured in the App Store revenue data. The vast majority of activity for the top commerce, communications and media properties are now coming through mobile devices.

By weight of users and their propensity to engage, iOS enables about 50% to 60% of mobile economic activity.

Based on assumptions of revenue rates for mobile services and iOS share of engagement, my estimate of the economic activity on iOS for 2017 is about $180 billion. Including hardware sales, the iOS economy cleared about $380 billion in revenues 2017.

Additional assumptions around growth rates suggest that iOS economy will achieve the half trillion revenue rate in 2019. Valuing this, especially as a part of Apple's intrinsic value, is a challenge but it's probably worth doing. There are implications in the robustness or sustainability of the underlying business.
