Hi guys,
a newbie to this forum (though not to value investing)
Was reading through this stock's FS and found an odd line in their cash flow statement without any accompanying financial notes.
It's called "Cash Restricted in Use Over 3 Months" under cashflows from Investing activities.
It's outflow jumped many times compared to last year, so just wondering if any of our VB folks here know what this line meant?

Believe that is their cash in some sort of short-term fixed deposit. If you check out the Annual Report there is a section under cash equivalents that says : Fixed deposits (maturity of over 3 months). So that looks like the cash put into FDs and classed as investing activities.
