[QUOTE=Hence, it looks like Petersen was counting the capital expense as an addition to the operating expense when, in fact, it's already included. [/QUOTE]
I think the "pre-production costs expensed under GAAP" refers to R&D expense which for the last quarter was $68.4million (it appears on the income statement on page 5 of the last 10Q.) Purchases of property and equipment, excluding capital leases appears under "Cash Flows from Investing Activities" in the Cash Flow Statement on page 7 of the same 10Q; it was $67.9 million for the last quarter. The 67.9 million will be depreciated on future statements. Depreciation will be an expense on future income statements, but it will also be a non cash expenditure so it will be added back on future cash flow statements as a "source" of funds.
Some of the type of expenses related to the Model S that appeared as R&D before poduction will now start appearing as "Cost of Revenue" expenses; Model X expenses will remain as R&D.
The statements that will be published on Wednesday should provide more clarity on how tight the company's cash position really is. I think Petersen overstates the "going concern" statement ( I am under the impression that those types of auditors' comments are more of an issue with 10k's than 10q's but Petersen is/was a CPA but not me.)
