To empirically examine our research questions, we use data on major customers from the Compustat Segment file to build a unique and comprehensive set of two-member supply chain dyads of customers and suppliers. We use Audit Analytics to identify the disclosure of material weaknesses under SOX 404 and SOX 302. As we test the effect of ICWs on the duration of customer-supplier relationships, our sample is exclusively post-SOX and runs from 2004-2012. Our sample ends in 2012 as we must look forward to observe relationship termination.
