U.S. presidents are judged by the goals and accomplishments of their first 100 days in office. As President Biden’s first 100 days draws to a close, it is useful to consider how that same standard can be applied to GC/CCOs that join fund managers anew. The first 100 days of a GC/CCO’s tenure provide a singular opportunity for him or her to set the expectations and tone for legal and compliance going forward. The 100‑day mark also provides a useful goalpost for new GC/CCOs to aim at when fulfilling certain crucial objectives. This first article in a three-part series offers advice for starting the GC/CCO role on the right foot, including how to prepare before day one and the best way to approach the first 100 days. The second article will explore how new GC/CCOs can accomplish two crucial goals in the first 100 days – gathering knowledge about the firm and building the foundation for solid relationships with key people. The third article will outline how new GC/CCOs can balance their day-to-day legal and compliance work as they settle into the job and organization, as well as how to identify and advocate improvements and changes.
