Wellington Management will determine whether a company is a growth company based on traditional and other measures of growth, such as whether the company is included within a third-party growth index (e.g. the Russell 3000 Growth Index or the MSCI USA IMI Growth Index) and/or whether the company exhibits growth characteristics based on certain metrics, such as earnings per share (EPS) growth and/or revenue growth. A company may be determined to be a growth company under any of these factors. Show less
