- Related Party Transactions: Certain lenders to the credit facility have provided and may continue to provide investment banking and commercial banking services to MPLX and its affiliates.
Investor Verification Checklist
- Verify the exact exchange ratio applied to specific ANDX unit holdings (1.135 vs. 1.0328) to confirm post-merger ownership.
- Review the full text of the Amended and Restated Credit Agreement (Exhibit 10.1) for detailed covenants and default events.
- Confirm the status of the $500 million 5.500% senior notes due 2019 assumed by MPLX, as they mature shortly after the merger.
- Check the pro forma financial information included in the Registration Statement on Form S-4 (Registration No. 333-231798) for combined financial metrics.
- Monitor MPLX's credit rating, as it directly impacts the interest rate margins on the new $3.5 billion credit facility.
