Undervalued transactions under insolvency law face look-back periods for avoidance and expert valuation scrutiny. Undervalued transactions are subject to avoidance where the liquidator or resolution professional shows that the transaction was made within the relevant look-back period before the initiation date and insolvency commencement date. Transactions with any person fall within one year of that period, while transactions with a related party fall within two years. The Adjudicating Authority may call for an independent expert to assess evidence relating to transaction value.
