Your executive summary should include a very short overview of your funding status.  This section should include four pieces of information: how much you have raised to date, who made that investment (e.g., founders, angels), how much you are raising in this round and the very high-level intended uses of this capital (e.g., complete technology, increase sales staff).  This section should be kept very brief, integrated into 1 to 3 sentences or a few bullets.

If you're not exactly sure how much you are raising put a range in the executive summary.  This isn't an issue as VCs understand that there are always different scenarios - more/less staff or a longer/shorter period before your next fundraising.

Do not put a valuation of the company in the executive summary.  Including a pre- or post-money valuation can appear to be presumptuous and if your expectations are too high it can make investors lose interest before your first meeting.  Remember, the purpose of this document is to get a meeting, not close the whole deal.

It's good to be forthcoming about your financial requirements; investors are comfortable talking about money.  Keep this section very simple and you'll be one step closer to landing a meeting.
