> I think the ‘answer’ here is to take MC, subtract net cash
no – if by net cash you mean cash adjusted for debt. Don’t adjust MC for debt.
> DH, not sure I understand your definition of surplus assets.
Any asset not required to generate earnings.
When it comes to cash, the standard approach is to find the operating cash required to run the business – e.g., cash sitting in cash registers, overnight float, earmarks for A/P, etc. Most firms carry more cash than this – that extra cash is potentially a surplus (wasting) asset that incurs cost of carry and opportunity cost. A quick calc of surplus cash would be current cash less the minimum cash level over the past few years.
Surplus assets obviously contribute to market cap, but they don’t change in value as earnings change. Naive P/E analysis assumes they do.
No need to bring in BV’s here.. unrequired/misleading complication.
I’m not sure why people are bringing in debt here. Shareholders have a claim that is essentially the annuity value of NI. If the firm (aka, the “wallet”) has surplus assets in it – nonoperating cash, paintings, $20 bill sitting in an envelope – those surplus assets increase market cap dollar for dollar. Once you do this however P/E gets a little funny, and adding $1 to earnings will _not_ increase market cap by $1 * P/E.
There is no need to bring debt into this.
