Key Terms

4 terms

private loan portfolio financial

"recent activity in its private loan portfolio. During the first quarter"

A private loan portfolio is a collection of loans held by a non-bank lender, investment fund, or other private investor rather than traded on public markets. Think of it as a basket of IOUs—each loan is a promise of future payments that can vary in credit quality, interest rate and liquidity. Investors care because these portfolios can offer higher yields than public bonds but also carry greater credit risk, valuation uncertainty and limited ability to sell quickly.

first lien senior secured term loan financial

"in an incremental first lien senior secured term loan and $13.1 million"

A first lien senior secured term loan is a company loan that must be repaid before other debts and is backed by specific assets as collateral; it carries a fixed schedule for principal repayment over a set period. Think of it like a first mortgage on a house: if the borrower can’t pay, this lender has the first right to the pledged assets. Investors watch these loans because their priority and collateral reduce credit risk and influence expected recovery, interest costs, and a company’s overall financial flexibility.

delayed draw term loan financial

"senior secured term loan and $13.1 million in an incremental first lien senior secured delayed draw term loan"

A delayed draw term loan is a financing agreement that lets a borrower take one or more lump-sum loans from a lender at agreed future dates within a set time window instead of receiving all funds up front. It matters to investors because it changes when and how much debt a company will carry, affecting cash flexibility, interest costs and risk exposure—think of it like an approved credit line you only tap when you need cash for a project.

revolver financial

"$10.9 million in a first lien senior secured term loan, $1.6 million in a first lien senior secured revolver"

A revolver is a revolving credit facility — a line of borrowing a company can draw, repay and draw again as needed, similar to a corporate credit card for short-term cash needs. It matters to investors because it provides liquidity and flexibility to cover expenses, smooth cash flow swings, or bridge financing gaps; the size, cost and covenants of the revolver affect a company’s interest costs, financial health and default risk.
