The Recovery Expense Fund (REF) created by issuers of listed debt securities, enables Debenture Trustees to recover expenses related to enforcement or legal proceedings in case of default. The modifications specify that prior approval from debenture holders is not required if REF is used for defined purposes such as obtaining consents, conducting meetings, filing court applications, engaging legal consultants, or asset recovery. The trustees must notify holders and the designated stock exchange, maintain proper accounting, and submit independent auditor certificates. The stock exchange is required to release REF amounts within five working days upon intimation.
