first lien senior secured debt investments financial

"90.1% invested in first lien senior secured debt investments"

delayed draw term loan financial

"a 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

"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.

cost basis financial

"with a cost basis totaling $61.4 million"

The cost basis is the original amount you paid to buy a stock, bond, or other investment, plus any fees or adjustments that change that original cost over time (for example, reinvested dividends or stock splits). It matters because profit or loss — and the taxes you owe when you sell — are calculated by comparing the sale price to this purchase amount; think of it like the purchase price of a house used to determine your gain when you sell.
