First Mortgage Bonds financial
"issued and sold (i) $60,000,000 aggregate principal amount of its First Mortgage Bonds"
First mortgage bonds are debt securities backed by a company’s property, granting bondholders the primary legal claim to that real estate if the issuer cannot pay. Think of them as being first in line for repayment, like a homeowner’s mortgage lender who gets paid before other creditors. For investors, this priority and the tangible collateral typically make these bonds less risky than unsecured debt, which can mean lower yields but greater protection in bankruptcy.
Supplemental Indenture regulatory
"issued pursuant to the Twenty-ninth Supplemental Indenture to NW Natural’s Mortgage and Deed of Trust"
A supplemental indenture is a written amendment to the original bond agreement that changes specific terms of a debt contract, such as payment schedules, interest rates, collateral or covenant protections. Investors care because it alters the legal rights and risks tied to a security — like renegotiating a mortgage where the lender and borrower agree to new rules — and can affect a bond’s credit quality, yield and market value.
