Item~2.01 (completion of an acquisition or disposition) and Item~2.05 (exit or disposal costs) are the natural counterparts of \texttt{ma\_integration} and \texttt{cost\_reduction}; Items~5.02 and 8.01 are controls. Confidence intervals are Wilson intervals. These are consistency proxies: an item code says that an event of the kind was reported, not that the model's mention is correct, so neither probability is a precision or a recall.28\end{tablenotes}29\end{threeparttable}30\end{table}31
