Generally speaking, investible assets will consist of two pieces: surplus
and loss reserves. The 1986 problem uses the term investible liabilities
for the latter, but they are the same thing, since loss reserves are on the
liability side of the balance sheet. (I suppose it's possible that some
portion of the loss reserves might not be available for investment, or
there could be liabilities other than loss reserves which are investible,
so in these cases the term investible liabilities - referring to the
investible portion of all liabilities - might be more accurate, but I think
it's unlikely this would ever come up in a problem.)
Hope this helps.
