Negotiating points

Prior to entering into this ASA, the parties will need to consider and agree:

  • discount rate: the discounted price per share (expressed as a percentage) at which the ASA investor will receive shares in the qualified financing round
  • valuation cap: if agreed, the cap on the valuation of the company for the purpose of calculating the price at which the advance subscription will convert into shares on a qualified investment round
  • default valuation: the default valuation of the company which will be used to calculate the conversion price of the advance subscription in circumstances where conversion occurs on the agreed longstop date or the company’s insolvency
  • longstop date: the longstop date on which (and in the absence of a prior qualifying financing round) the ASA will automatically convert into shares
  • qualified financing round: the minimum amount of funding which the company must raise before that funding round will count as the qualified financing round under the ASA which results in the conversion of the advance subscription into shares
  • subscription amount: the amount of the investor’s advance subscription
