4 terms

trade receivables securitization facility financial

"The Credit and Security Agreement is a $500,000,000 trade receivables securitization facility backed by trade receivables"

Adjusted Term SOFR financial

"MM Funding’s borrowings bear interest at Adjusted Term SOFR plus 0.700%"

Adjusted term SOFR is a forward‑looking interest benchmark based on short‑term overnight Treasury repo rates, with a small extra amount added to reflect differences from legacy rates. Think of it as a quoted price that has been nudged to make payments comparable to older benchmarks; it matters to investors because it directly influences borrowing costs, bond yields and cash‑flow forecasts, affecting valuations and hedging outcomes.

amortization event financial

"The Credit and Security Agreement includes an amortization event related to a payment default"

material definitive agreement regulatory

"Item 1.01. Entry into a Material Definitive Agreement"

A material definitive agreement is a legally binding contract that creates major, long‑term obligations or rights for a company, such as loans, asset sales, mergers, or supplier deals. Think of it like a mortgage or lease for a business: it can change future cash flow, risk and control, so investors watch these agreements closely because they can materially affect a company’s value, financial health and stock price.
