Collateral Trust Bond

When a company takes shares they own of another company, tosses them in an escrow account, and uses those stocks as collateral for raising money.

That is, those shares become collateral for some other financial transaction.

Example: You own a company that makes non-ouchy intimate hair-removal products. You stumble across a formula guaranteed to get rid of, uh...knuckle hair...forever. Only one little hiccup: you need cash to make and market the product.

Your company owns Apple stock. So you throw the Apple stock into an escrow account and go to the bank. The bank uses the stock as collateral to give you a loan. Now you have the cash to go fund the build of the Knuckle-Offer.
