A large-sized company is defined as a company having a market capitalization at the time of purchase that falls within the market capitalization range of companies in the Russell 1000 Index. The portfolio management team follows a growth style of investing and seeks to identify what it believes are durable franchises that have favorable long-term growth prospects and trade at reasonable valuations. A durable franchise is a company whose competitive advantages Lord Abbett believes should persist over time. These companies exhibit many of the following characteristics: a strong brand name, dominant market share, high barriers to entry, scale advantages, recurring revenues, strong free cash flow, patent protection/intellectual property, pricing power, and competent management. Equity securities in which the Fund may invest include common stocks, preferred stocks, equity interests in trusts (including real estate investment trusts and privately offered trusts), partnerships, joint ventures, limited liability companies and vehicles with similar legal structures, other instruments convertible or exercisable into the foregoing, and other investments with similar economic characteristics. The Fund may invest up to 10% of its net assets in securities of foreign companies, including emerging market companies, American Depositary Receipts (ADRs), and other similar depositary receipts. In addition to ADRs, the Fund generally defines foreign companies as those whose securities are traded primarily on non-U.S. securities exchanges. The investment team may also consider the risks and return potential presented by environmental, social, and governance (ESG) factors in investment decisions. The Fund may sell a security when the Fund believes the security is less likely to benefit from the current market and economic environment, or shows signs of deteriorating fundamentals, among other reasons. The Fund may deviate from the investment strategy described above for temporary defensive purposes. The Fund may miss certain investment opportunities if defensive strategies are used and thus may not achieve its investment objective. Show less
