The primary responsibility of an Investment Committee (IC) in a corporate or financial institution involves evaluating, vetting, and approving or rejecting major capital expenditure proposals, M&A transactions, and high-stakes portfolio investments. Committee members scrutinize financial models, risk assessments, and strategic alignment to ensure that deployed funds comply with institutional guidelines and fiduciary duties. By acting as a strict governance checkpoint, the IC protects the organization from taking on excessive financial exposure or making ill-advised asset allocations.
