Nearly 5000 delegates from around the world are currently at the ICC in Sydney to attend the World Congress of Accountants until 8 November.

The Chartered Accountants Australia New Zealand team is providing daily insights from selected sessions for those who cannot attend. Here are the coverage highlights from day 3:

Valuations – art or science?

Simon Dalgarno, Managing Director and Shareholder, Leadenhall Corporate Advisory Pty Ltd

Rajeev Shah, Managing Director and Chief Executive Officer, RBSA Advisors

Leading valuers say the current 'crazy' valuation of technology stocks highlights the importance of valuation fundamentals.

But amid this volatility, Shah says there are a number of fundamentals of valuation that never change and must be established to generate a sound valuation.

The innovation-led finance function

Jacqueline Chan, Managing Director and Chief Financial Officer, DBS Bank (Hong Kong) Ltd

Janelle Hopkins, Executive General Manager, Finance and Group Chief Financial Officer, Australia Post

Daniel Papallo, Global Planning and Finance Transformation Controller, Cochlear

Senior finance executives say that creating the right people culture is vital to building an innovation-led finance function.

Hopkins says the only differentiator between a good and bad finance function is "the people and capabilities, and the systems and tools", which why she started with people. She first talked with her leadership team about the need for the company to change and transform.
