English to Polish Bus/Financial Finance (general)

A key development came in 1997, with the creation of a PFO to facilitate the issuance of an asset-backed security based on music royalty streams. Music royalties were bundled into catalogs that continue to make payments to the royalty owners (in other words, the artists or their estates) long after the initial recording of an album or, more often today, the recording of a digital single. Such royalty streams can form the basis of bond payments on an asset-backed security.

Wiem, że asset-backed security to papier wartościowy zabezpieczony aktywem, ale o co chodzi z tymi bond payments?
