Key Terms

5 terms

qualified notice regulatory

"Concurrent with this announcement we are providing qualified notice to brokers"

A qualified notice is a formal communication that meets the specific wording, timing and delivery rules set out in a contract, corporate policy or law so it is legally effective. Think of it like a certified letter that ticks every checkbox required by an agreement. Investors care because only a qualified notice can trigger rights or changes — such as deadlines, payments, defaults or board actions — and thus can materially affect a company’s obligations and share value.

treasury regulation section 1.1446-4(b) regulatory

"under Treasury Regulation Section 1.1446-4(b) and (d)"

A U.S. Treasury regulation that explains when and how a purchaser of a partnership interest must withhold tax when the seller is a foreign person, implementing the withholding rules of Internal Revenue Code section 1446. It matters to investors because it can affect the cash a buyer must hold back at closing (similar to a cashier keeping part of a sale until taxes are cleared), which changes deal proceeds, tax reporting, and timing of when funds become available.

effectively connected regulatory

"income that is effectively connected with a United States trade or business."

Income or gains that are treated for U.S. tax purposes as arising from a taxpayer’s regular business activities in the United States; think of it as money that is 'tied to' active operations in the U.S. rather than passive holdings. Investors care because income deemed effectively connected often faces different tax rates, withholding rules and reporting requirements, which can change after-tax returns and the paperwork or withholding applied to payouts.

federal income tax withholding regulatory

"subject to federal income tax withholding at the highest applicable"

Federal income tax withholding is the portion of an employee’s wages that an employer automatically sends to the government to cover that person’s expected federal income tax bill. Think of it like an automatic savings pot taken from each paycheck so the worker doesn’t face a large one-time tax payment; for investors, withholding affects disposable income, cash flow planning, and the timing of tax liabilities tied to salary, dividends, or retirement distributions.

withholding agents regulatory

"Nominees, and not MPLX, are treated as the withholding agents"

A withholding agent is an entity (often an employer, broker, or payer) that is legally required to hold back and remit taxes or other required amounts from payments made to a recipient, such as wages, dividends, interest, or contractor fees. For investors, this matters because withheld amounts affect the cash they receive, determine tax reporting and potential refunds, and influence net returns in cross-border or taxable transactions — like a cashier keeping part of a payment to cover a bill.

Qualified Tax Notice

Concurrent with this announcement we are providing qualified notice to brokers and nominees that hold MPLX units on behalf of non-U.S. investors under Treasury Regulation Section 1.1446-4(b) and (d) and Treasury Regulation Section 1.1446(f)-4(c)(2)(iii). Brokers and nominees should treat one hundred percent (100%) of the Partnership's distributions to non-U.S. investors as being attributable to income that is effectively connected with a United States trade or business. In addition, brokers and nominees should treat one hundred percent (100%) of the distribution as being in excess of cumulative net income for purposes of determining the amount to withhold. Accordingly, the Partnership's distributions to non-U.S. investors are subject to federal income tax withholding at the highest applicable effective tax rate. Nominees, and not MPLX, are treated as the withholding agents responsible for withholding on the distributions received by them on behalf of non-U.S. investors.
