can someone please tell me what accounting theory was used in this article? Its only 180 words.

the list of accounting theory for this assignment is public interest theory, capture theory, private interest theory, legitimacy theory, positive accounting theory and political hypothesis. i have feeling its either public interest theory or private interest theory but i am not 100% sure which one is used.

Also could you briefly tell me how that theory was used in this article? I just need little help to start on this assignment.

Thanks alot!

Article 4 Ramsay Health Care (RHC) John McDuling 184 words 30 August 2011 The Australian Financial Review AFNR First 26 English Copyright 2011. Fairfax Media Management Pty Limited. Shares in Australia's largest private hospital operator are up 27 per cent in the past 12 months, easily outperforming the broader market, which has fallen about 4 per cent over the same period. Investors last Thursday pushed the stock 4.2 per cent higher after the company reported a 2011 net profit of $198.4 million, a 34 per cent increase on the previous year, on revenues of $3.72 billion, a 9.4 per cent increase. Strong performances across its Australian hospitals and greater contributions from brownfield developments drove the result, it said. The stock is trading on a multiple of more than 15 times 2012 earnings, above the broader market average of about 12 times, but below the healthcare sector average of more than 20 times.
