The fundamental research emphasizes the sustainability of a business's competitive advantages, revenue and margin drivers, and cash generation capacity. This research is aided by a proprietary screening tool that helps to identify companies with these characteristics. Wellington Management also evaluates the following regarding a company: capital allocation discipline, off-financial statement factors, management track record, and analysis of products and competition.
