Ann: Diploma reports strong first half profit , page-10

I haven't previously followed DGX so forgive me if this has already been covered....

Looking at the result most of the improvement is due to a large decrease in administration costs ($1.36 million) and a smaller decrease in other expenses ($0.50 million).

This is great to see. However, does anyone know what specific costs were taken out of the business and how this was done so drastically...the change period on period in both cost lines is very high in percentage terms.
