Changes coming to the Lifecycle (L) Funds — (November 29, 2018) We are planning adjustments to the L Funds in an effort to improve your investment outcomes. Effective in January 2019, we will increase exposure to international stocks (the I Fund) from 30% to 35% of the overall stock allocation in all L Funds. The L Income Fund stock allocation (C, S, and I Funds combined) will increase from 20% to 30% over a period of up to 10 years. The L 2030, L 2040, and L 2050 overall stock allocations will hold steady for a period of years before resuming their transitions from stocks to bonds. In addition to improving investment outcomes, this pause will align the L 2030, L 2040, and L 2050 Funds with the L 2060 Fund, which will be introduced in 2020 with an initial stock allocation of 99%.
