Objective: investigate the impact of an intraoperative coding sticker (ICS) on the accuracy of coding in endoscopic sinonasal procedures. Methods: this was a two-cycle audit evaluating the accuracy (and financial impact) of intraoperative coding of sinonasal procedures at a single tertiary centre. An ICS was introduced following consultation with the coding department. The accuracy of coding was measured before (cycle 1) and after (cycle 2) the ICS was introduced to a pilot firm and compared to a control firm. The ICS was used in 35% of the pilot firm cases. Results: the accuracy of clinical coding for endoscopic sinus surgery was 60% in the first cycle. Switching to the ICS has improved the accuracy in that firm from 50% in first cycle to 70% in the second cycle (p = 0.936; Chi-squared test). The median reimbursement for endoscopic sinus surgery was equal in both cycles of £1493.00 per patient. However, inaccurate coding resulted in £109.92 excess tariff payment in first cycle and £130.96 deficiency in the second cycle. Users of ICS reported it to be easy to use for clinicians, staff and clinical coders, whilst minimizing human error. Conclusions: The integration of the ICS improves the coding in sinonasal procedures and offers low-fidelity option alternative to live coding on the computer. The accuracy was not statistically significant in the study possibly due to the low number of observations. This can allow a precise coding standard with reliable service remuneration.

We examine the long-term performance of 225 IPOs listed on the Johannesburg Securities Index (JSE) during the period from 1996 to 2006. The buy-and-hold abnormal return (BHAR) method and the calendar time portfolio (CTP) approach have been employed to measure the long-run performance of IPO stocks. The findings reveal that IPOs are highly underpriced when the abnormal returns are estimated by BHAR methodology. However, the use of control firm approach instead of market index for measuring abnormal performances significantly reduces the magnitude of this underpricing reported in previous studies on South African IPO stocks. Our major contribution to the literature is that we apply –for the first time- the calendar time portfolio approach to assess the aftermarket performance of IPOs listed on the JSE. In addition, we use control firm approach instead of market index to estimate the abnormal returns. These are the two significant cases which were not documented in previous research on measuring long-term performance of South African IPO stocks

ABSTRACT: We find that the likelihood of forced turnover in the CEO and CFO positions is significantly higher for firms in the aftermath of option backdating than in propensity-score matched control firms. Forced turnover occurs in about 36 percent of the accused firms. The forced turnover rates for CEOs and CFOs are similar and several times higher than normal. The displaced managers are further punished by the managerial labor market, as they are much less likely than control firm managers to be rehired at comparable positions. We also find that backdating firms restructure CEO compensation to rely less on stock options. Finally, we learn the higher turnover extends to the General Counsel. While boards are often viewed as unresponsive to criticisms involving executive compensation, they did respond quite decisively to option backdating allegations and the accompanying adverse publicity. Data Availability: All data used in this study are publicly available from the sources indicated.

This study is aimed to examine the effect of corporate governance on financial performance with variable control firm size. Corporate governance is measured using board of commissioners, proportion of outside commissioners, board of directors, institutional ownership, managerial ownership, and audit committee. Financial performance is measured using tobins q. This study used variable control which is firm size where as measured used log natural assets. This study used sample were as public listed companies in Indonesian Stock Exchange (IDX) in period 2011-2015. Thus, this sampling method used purposive sampling technique. The result of this study showed that board of commissioners, board of directors, institutional ownership, managerial ownership, audit commitee not influence to financial performance. This study is showed proportion of outside commissioners influence to financial performance. The purpose study determine where is to add more independent variable. In addition, financial performance is measured used  EVA (Economic Value Added) and expanding the corporate companies. More over the result in this study is have implications to each hypothesis.
