In an effort to increase the usefulness of 20-Fs\, the SEC recently enacted a regulation to accelerate the deadline of 20-F f iling from six months to four months after the fiscal year-end. The ration ale is that the shortened reporting lag would improve the informational re levance of 20-Fs. In this work we propose a jump additive model to evaluat e the SEC’s rationale by investigating the relationship between the timeli ness of 20-F filing and its decision usefulness using the market data. The proposed model extends the conventional additive models to allow possible discontinuities in the regression functions. We suggest a two-step jump-p reserving estimation procedure and show that it is statistically consisten t. By applying the procedure to the 20-F study\, we find a moderate positi ve association between the magnitude of the market reaction and the filing timeliness when the acceleration is less than 17 days. We also find that the market considers the filings significantly more informative when the a cceleration is more than 18 days and such reaction tapers off when the acc eleration exceeds 40 days.\n\n\n Speaker\n\n\nYicheng Kang is an Assistant Professor in the Department of Mathematical Sciences at Bentley University .
