What is cross-collateralization and why might a lender ask for it on a second loan to the same corporation?

Cross-collateralization is a structuring choice where a lender extending a second loan to a corporation it already lends to arranges for its existing collateral to also secure the new loan, rather than taking entirely separate, ring-fenced collateral for each loan. In some structures, it works both ways, so that both the original and the new loan are secured by the combined pool of collateral rather than each loan being tied only to its own specific assets.

A lender asks for this because it simplifies and strengthens its overall position: instead of tracking which specific assets secure which specific loan, and potentially finding one loan under-secured while excess collateral value sits unused for the other, the lender has one combined pool of collateral available against everything the corporation owes it. For the corporation, this can mean that a default on one loan puts collateral originally associated with a different, otherwise healthy loan at risk as well, since the two are no longer treated as fully separate for enforcement purposes. This is a meaningful term worth understanding, and potentially negotiating against, before agreeing to a second loan from an existing lender.
