I agree with this. There's nothing shady in the "new" metric - the name describes what the number is supposed to show, any investor can use that information as he/she sees fit. All the data is in the financials anyway, we can all construct our own metrics. I've always had an aversion toward the much accepted term "burning cash" for example, to me it sounds like very poor use of capital to burn it. "Investing in future growth" seems much better. It's all in the eye of the beholder, as always.
Johan, you're sort of right in what you say however the issue surrounding the emotive term Cash Burn is a good deal more complex. Sadly when it comes to market manipulation complexity creates openings for FUD.
This comes down to word-play on accounting terminology that media pundits and a lazy audience is not interested in explaining or understanding.
When you're running a business it is pretty natural in my view to separate:
A. the concepts of monthly overheads into the cash burn category
and
B. Developing a new product, launching a media campaign, hiring new staff and buying more plant and machinery into the investing in growth category.
The trouble with this is that out of all of the above ONLY buying more plant and machinery sits on the accounts under the column marked 'Investing Activity'. All the rest belongs on the accounts in various categories that can be construed (or misconstrued) as cash burn. For example the is no category in accounting language for 'Investing In People', certainly not in the 'Investing Activity' column. Most likely it goes to SG&A which is the very definition of Cash Burn.
What Wheeler has done with his Cash Flow from Core Operations subcategory is to strip out all of the stuff that a business person would consider investing in growth. For example R&D for developing new products in addition to the products being sold by the 'Core Operation'.
However it gets even more complicated and FUD-prone than that when viewed through the eyes of Automotive Industry pundits including for example morons like Mark Speigel. While it would seem obvious in Silicon Valley that investing and staffing up for production of a new and ground-breaking product like the Model X was "investing activity" or investing in growth rather than a component of Core Operations of building, selling and incrementally improving Model S (even though it is not strictly Investing Activity in accounting language). In the automotive industry at large, R&D and staffing up for a new car model is not even colloquially considered an investment. It is literally viewed as cash burn and an every-day cost of keeping the lights on - because 130 years after the ground breaking invention of the internal combustion engine, incremental R&D expenditure by the automotive majors that grew up around it, while absolutely enormous in terms of cumulative cash burn, has produced practically nothing by way of competitive advantage for one over another. The FUDsters pitch is that Tesla being an automotive business should be regarded in the same light.
Wheeler's counterargument to the FUDsters is that Tesla has two things going on simultaneously. A Core Operational Automotive and Energy Storage business that is building and selling cars and batteries with positive cash flows i.e. Operational Leverage and separately it has Growth Activities going on which cost money that Core Operational Business was able to fund 45% in Q4 2015 and this year will on balance be able to fund slightly more than 100% for the full year thereby alleviating the need to raise cash. Presenting this counterargument to the FUDsters is definitely a PR move. A good one too. It's about time they explained this because it's true. It is also a very significant distinction from the business of other automotive companies that TSLA shareholders should be aware of. The fact that the Spiegels of this world don't and won't understand this is useful.
BTW the difference in what I am saying and what Elon is doing is just that. He is trying to persuade people of exactly the same thing but he doesn't need to get involved in a verbal bun fight with the skeptics because he can build the product and deliver the results to shut them up (and in the case of vested skeptics, defund their shorts). The point of saying it before he does it is to expose an information advantage that is actionable for investors in advance of events unfolding. This is why what I say is often counter-intutive and controversial, it is because the guy is doing counter-intuitive and controversial things. The future is both counter-intuitive and amenable to the scientific method. Musk is irrefutable living proof of it (and rather less importantly so is my track record of pointing to it). This is how Musk has been able to go all in with giant projects. He's not guessing and hoping things will turn out OK. Neither am I. Just trying to do my bit to accelerate the (inevitable) advent of electric vehicles by defending this mission from BS and I hope to some extent assisting in transferring wealth and the influence it brings from really bad people to really good ones by debunking some of the prevailing misperceptions and the deliberate FUD that is designed to produce the opposite effect.
