The Fund most likely bought in via the CR placement (25c), as in their June portfolio update they report TAW as a key detractor over the month, -18.8% (http://www.asx.com.au/asxpdf/20170707/pdf/43khxsfccfctqn.pdf).
And it seems that they have been accumulating, averaging down, as in their July portfolio update they report TAW as a key positive contributor, +12% (http://www.asx.com.au/asxpdf/20170816/pdf/43lgf35n9skn4h.pdf).
Their investment strategy process shows confidence in the long term potential of TAW:
"The manager uses a proprietary research process developed over many decades with a proven long term track record."
