Da Italiano a Inglese Legale/Brevetti Legale: Contratti Contract of Employment

The context is a standard contract of employment for managers in a particular company. In terms of this contract, a new service allowance is being granted:

"La nuova indennita' potra' assorbire fino a concorrenza quanto corrisposto a titolo di bonus individuale o per analoghe indennita' riconosciute..."

From the glossary I established that the term 'assorbire' can be translated as 'absorbed/assimilated'. Yet, I can't seem to find an adequate translation for the whole sentence.

First of all, I'm not sure I'm properly understanding the sentence. My (tentative) interpretation is that the new indemnity shall be presumed incorporated in the bonus. Or am I off-track?

Thanks !!
