Quick model to illustrate the problem -
1,470 60kWh sales @ $80,000 = $117.6m
1,715 85kWh sales @ $90,000 = $154.4m
1,715 P85 sales @ $100,000 = $171.5m
total
4,900 = $443.5m
ZEV Credits = $68m
Development Cash = $7m
Total = $518.5m
Actual = $562m
Missing = $43.5m??? From web merchandise and retail sales? We are talking like $8,900/car worth of revenue.
If CAFE prices equal GHG prices, then going off the model in the OP that would be worth ~$7,200/car. Totally speculative though, and is based only on EPA guidance of $23/Mg of CO2 with a multiplier of 2. Current CO2 price in Europe is ~$4/Mg, but thats because of a collapse. It's been as high as $40/Mg before the financial crisis, with many predicting $100+/Mg.
Regardless, its the only (potentially) missing line item which is at the correct scale (that I see anyways).
The "$7.0M Development Cash" is not part of the "Automotive Sales", it is listed as a separate item in the Shareholders Letter. The powertrain sales, however, are not listed as a separate item anywhere else, and are included in "Automotive sales".
So assuming that Model S ASP is $95,000 (including service plans, accessories, etc.), the total Models S automotive sales come at 4,900 x 95,000 = $465.5M. The remaining 555.203 - 465.5 = $89.7M is the total for Regulatory credits and powertrain sales. The most frustrating thing is lack of clarity on what ZEV credits entail, just ZEV (state) or ZEV combined with GHG (federal) credits. So the conclusion is that 89.7 - 68 = $21.7M is either powertrain sales or combination of powertrain sales and federal regulatory credits.
We will have to wait for 10-K filing to sort this out.
