Investment Process: Wellington Management Company LLP, the Funds subadvisor (the Subadvisor), seeks to construct a broadly diversified portfolio across sectors and industries. The Subadvisor predominantly employs a bottom-up fundamental research approach across sectors to identify companies with potential positive changes in their business that the Subadvisor believes may lead to outperformance, while seeking to limit exposure to risk. However, with respect to the biotechnology and pharmaceutical industries, the Subadvisor relies upon a quantitative process to manage the Funds exposure. The Subadvisor also seeks to minimize the Funds exposure to risk by diversifying the Funds investments over securities issued across various industries and sectors. The Subadvisor may consider selling a security if valuation and sentiment indicators suggest the inflection point is being embraced and/or fully valued by the market or if the investment thesis is impaired or no longer valid. To better assess strategic business issues that impact the performance of a company, the Subadvisor may also give consideration to financially material environmental, social and/or governance (ESG) factors. The Subadvisor has discretion to determine the materiality of, as well as the level at which, financially relevant ESG factors are imbedded into its overall fundamental analysis when making an investment decision.
