Keep in mind that performance and expenses are only two of several factors that you should consider when making investment decisions. Please consider the investment objectives and risks, as well as fees and expenses, carefully before investing. For this and other important information, you may obtain fund fact sheets and disclosure documents from your registered representative at (800) 947-0845 or through the website at www.countyla.com.* Read them carefully before investing.

Current performance may vary slightly from the performance data shown. Although data is gathered from reliable sources, we cannot guarantee completeness and accuracy. Performance data quoted represents past performance and is not a guarantee or prediction of future results. For performance data current to the most recent month end, please visit www.countyla.com. The investment return and principal value of an investment will fl uctuate so that, when redeemed, shares/units may be worth more or less than their original cost. All 457(b) Horizons Plan investment products except the Bank Depository Fund are not FDIC-insured and may lose value.

The net returns shown above refl ect fund operating expenses, but they do not include current administrative fees.12 For more information on how these administrative fees are assessed to your account, please refer to the Schedule of Participant Fees on page 4 of the Plan Highlights brochure or visit the website at www.countyla.com.

About the Investment OptionsThe Plan Administrative Committee (PAC), with the consultation of outside advisors not affi liated with Empower Retirement, has set the underlying allocation of the Horizons Target Date Funds and the Horizons Asset Class Investment Options (sub-funds). The PAC may change the underlying allocation to the sub-funds at any time, without prior notifi cation, pursuant to the investment guidelines established by the PAC.

1 About Separately Managed Funds/AccountsThe 457(b) Horizons Plan investment options are designed exclusively for the Plan. The PAC has selected underlying fund managers who may manage Plan assets through a separate account, thereby reducing the fund operating expense charged to participants. A separate account means Plan assets are invested separately from other clients of the fund manager. Therefore, performance data is based only on 457(b) Horizons assets. Registration with the Securities and Exchange Commission is not required for any of the Plan investment options.

2 Stable Income Fund Transfer InformationThe Horizons Stable Income Fund has a 90-calendar-day equity wash restriction on transfers to the Bank Depository Fund. Assets cannot be transferred directly from the Horizons Stable Income Fund to the Bank Depository Fund. Horizons Stable Income Fund assets must fi rst be transferred into the Target Date Funds or Asset Class Funds and remain within those funds for 90 calendar days. In addition, once a transfer out of the Horizons Stable Income Fund is initiated, all investment options are restricted from transferring into the Bank Depository Fund for 90 calendar days. The 90-calendar-day window restarts with the latest transfer out of the Horizons Stable Income Fund.

3 Important Information About the Target Date FundsThe Target Date Funds will be rebalanced automatically each quarter so they closely maintain their established percentage for each investment option. On an annual basis, the Horizons Target Date Funds will be adjusted to a more conservative asset allocation. When the Target Date Fund reaches its “targeted year,” the Target Date Fund will continue to exist as a “transition” fund with continued gradually declining exposure to equities for at least another 10 years beyond the targeted year until it is eventually absorbed into the Retirement Income Fund. The principal value of the funds is not guaranteed at any time, including on the target date. Review the fund fact sheets for more information.
