The investments and services listed may not be appropriate for all investors. Steward Partners Investment Solutions, LLC recommends that investors independently evaluate particular investments, and encourages investors to seek the advice of a Wealth Manager. The appropriateness of a particular investment will depend upon an investor’s individual circumstances and objectives.

In a fee-based account, clients pay a quarterly fee based on the level of assets in the account, for the services of a financial advisor as part of an advisory relationship. In deciding to pay a fee rather than commissions, clients should understand that the fee may be higher than a commission alternative during periods of lower trading. Advisory fees are in addition to the internal expenses charged by mutual funds and other investment company securities. To the extent that clients intend to hold these securities, the internal expenses should be included when evaluating the costs of a fee-based account. Clients should periodically re-evaluate whether the use of an asset-based fee continues to be appropriate in servicing their needs. A list of additional considerations, as well as the fee schedule, is available in the firm’s Form ADV Part 2 as well as the client agreement. Services rendered will be dependent on applicable agreements.
