French to English Tech/Engineering Engineering (general) Balance sheet entry abbreviation - amortization schedule

Hi all -

I am translating a report from statutory auditors for a large French publishing company.

I have been unable to find what this acronym stands for.

Below is the context.
The column headings are in caps followed by the entries.

DETAIL DES IMMOBILISATIONS ET AMORTISSEMENTS EN FIN DE PERIODE
NATURE DES BIENS IMMOBILISES
Logiciel
Inst/agct
Mat de bureau et informatique
Mobilier

Any suggestions would be greatly appreciated!
Michael

P.S. - If this a tech abbreviation, then I may need to move the category. LMK your thoughts in that regard as well. Thanks!
