Hi Junjing,
Referring to Page 71 on SPH Annual Report 2014, I’d just add up the top remuneration band of the six executives. It should stand somewhere around $9 million and comparing this with the company’s profit in the same year which is around $400 million, it is in the low single digit percentage and thus, would not consider be excessive.
For point number 2, we run through further in-depth how we analyse a company using all four quadrants (not just the mgt) and you can actually check out here for the actual application. Hope this helps in your learning and application :)
