Hi Papafox, when Jesse and I were speculating what FCF would look like if Model X hit 7k in Q1, there won't be over 3k worth of Model X in inventory. A few hundreds maybe. Tesla rarely produce a lot more than they deliver during a quarter (thus I suspect producing 20k in Q2 and delivering 17k is low balling it). So under the hypothetical scenario of Q1 producing 7k Model X, most of them would be delivered. Granted, there will be inventory left for finished goods that are in transit, but it won't be much more than the ratio they usually carry.
Fallenone, my hypothetical scenario with 4600 Q1 completed-but-unsold Model X vehicles was not intended to depict the actual condition. Rather, it was intended to show how much additional FCF Model X could have generated if all the planned 7,000 Model X vehicles could have been built.
The important part of the exercise is to demonstrate that costs of the Model X vehicles were being counted twice in the methodology used: once when the labor and parts costs were included in Q1 ER, and again when the revenue from Model X vehicles that could have been sold was discounted by multiplying by 20% (and thus counting the cost of manufacturing a second time).
Here's a simple example: You have a product that sells for $9 and plan to produce 100 of them during the quarter. The gross margin for that product is 20% if all 100 can be built. Unfortunately, due to manufacturing issues, only 40 are built and sold. The company realized 40x $9 = $360 revenue, but how much Free Cash Flow could have been generated if all 100 could have been built and sold?
Let us say that the quarterly earnings report contained the cost for producing all 100 of these products since labor was already hired and on the property, third-party parts companies had already delivered enough parts for 100 products, and the company had already bought enough aluminum and other basic ingredients to build those 100 products. The likely cost reflected in the earnings report would be 100 x $9 x .80 = $720. To figure how much FCF was lost by not producing and delivering the remaining 60 products, you multiply 60 x $9 = $540. That is your answer. You can double-check the figures by adding $540 to $360 = $900, which is the total revenue brought in if 100 products had been built and delivered. You have already accounted for the cost of producing those 100 unites in the Earnings report ($720), which would yield a GM of 20%. The point I'm trying to make is that you don't multiply the revenue from selling those units by 20% GM, because then you would be counting your costs twice.
If you're looking forward at a quarter and no numbers are already included in an earnings report, sure, go ahead and multiply potential products created by the GM to come up with a contribution to FCF, but if you're looking back on an earnings report AND THE COST OF PRODUCING THOSE PRODUCTS HAS ALREADY BEEN BAKED INTO THE ER, don't multiply the potential revenue by the GM because then you will be double-counting the costs.
