Dexus (ASX:DXS) said draft external independent valuations have resulted in an estimated decline of around AU$24 million, or 0.2%, on book values across its asset portfolio for the six months through June, according to a Monday filing with the Australian bourse.

The value of the office portfolio fell around 0.4% due to marginally higher capitalization and discount rates, partially offset by market rental growth. The industrial portfolio's value increased 0.5% due to market rental growth and a slightly firmer discount rate, partly offset by a marginally softer capitalization rate, per the filing.

"The valuations reflect a stabilizing market that is being driven by fundamentals," said Dexus Group CEO Ross Du Vernet.

The company's portfolio of 175 assets comprises 27 office properties and 148 industrial properties.
