RT Journal Article SR Electronic T1 The Antidilution Death Spiral JF The Journal of Private Equity FD Institutional Investor Journals SP 35 OP 44 DO 10.3905/jpe.2002.320006 VO 5 IS 2 A1 Timothy J. Harris YR 2002 UL https://pm-research.com/content/5/2/35.abstract AB Private equity valuations in down rounds, when the portfolio company raises fresh money but the valuation is lower than in the prior round of funding, require careful computation because of previously negotiated antidilution provisions. These can be percentage-based or price-based antidilution. This article provides guidelines and an example of the calculations required to complete a down round when antidilution provisions are in force.
