There can be no assurance that 10 East will be able to identify investments that are positioned to benefit from its investment approach or that the investments identified will be able to realize, in whole or in part, the opportunities identified in any investment approach. Investing in alternative investments, including through 10 East, is inherently risky and illiquid. It involves a high degree of risk (including of significant and/or complete loss) and is suitable only for sophisticated and qualified investors. There is no guarantee that you will be able to sell, transfer or otherwise exit your investments or that you can do so at a specific price. Any historical, projected or expected returns presented herein are not guaranteed and may not reflect actual performance. No offer or sale of any securities or other investment instrument(s) will occur without the delivery of offering and other definitive documentation, and nothing herein shall otherwise constitute an offer to sell or constitute a solicitation of an offer (or recommendation) to buy, sell or hold any security (or other financial instrument), make any investment, or adopt any investment strategy, or constitute investment, legal, tax, accounting, regulatory or financial advice. 10 East members must seek their own such, and other, professional advice. No sale will constitute a binding agreement unless and until such documentation is finalized and, where applicable, fully executed. 10 East Partners LLC is an SEC-registered investment adviser. Neither Portage Technologies Inc. nor 10 East is a registered broker-dealer.
Certain information herein contains “forward-looking” information under applicable laws and otherwise (“forward-looking statements”). Such forward-looking statements may include, without limitation, expectations, projections (including in each case with respect to investment performance and/or investment term(s)) and anticipated business developments, among others. Forward-looking statements are not guarantees of future activities, performance or otherwise and should not be relied on in any respect. Forward-looking statements are subject to numerous assumptions, risks and uncertainties, which change over time, and 10 East assumes no duty to and does not undertake to update forward-looking statements. Actual results could differ materially from those anticipated in forward-looking statements.
10 East employees, principals, directors, partners and/or advisors (including each of their respective affiliates) invest, if at all, in 10 East offerings in amounts to be determined by such investors at the time of the applicable commitment(s) or investment(s), and have done so, and may continue to do so, directly with the underlying investment sponsor, where applicable, or otherwise outside of the investing entities in which 10 East members will directly invest. In connection with such investments, such investors are not expected to pay management fees or carried interest to 10 East or its affiliates, or bear expenses charged at the level of the investing entities in which 10 East members will directly invest (or will pay reduced rates). To the extent such investors do invest in a 10 East offering via the 10 East investing entities in which 10 East members invest, such investors will not typically pay management fees or carried interest to 10 East or its affiliates.
Past performance is not indicative or a guarantee of future results.
