AllianzIM U.S. Large Cap Buffer10 Mar ETF (MART) is an exchange-traded fund managed by Allianz Investment Management LLC that seeks to track the share price performance of the SPDR S&P 500 ETF Trust up to a predefined cap while providing a buffer against the first 10% of losses over a one-year outcome period, before fees and expenses; the fund primarily invests in FLEX Options referencing the SPDR S&P 500 ETF Trust, including call and put options such as SPY 02/27/2026 4.40 C, SPY 02/27/2026 682.95 C, SPY 02/27/2026 534.76 P, and SPY 02/27/2026 594.12 P, along with cash equivalents. Launched on February 28, 2023, and headquartered in Minneapolis through its adviser Allianz Investment Management LLC, a wholly owned subsidiary of Allianz Life Insurance Company of North America, the fund targets U.S. investors seeking large-cap equity exposure with defined risk parameters in the buffered outcome ETF segment; it operates principally in North American developed markets with assets under management of approximately $27.4 million as of July 31, 2025, and a net expense ratio of 0.74%. In a recent strategic reorganization announced in December 2025, the fund is scheduled to transfer its primary listing from NYSE Arca to Cboe BZX Exchange and undergo a name change to AllianzIM U.S. Equity Buffer10 Mar ETF, effective on or about December 22, 2025, while maintaining unchanged investment objectives, strategies, and management teams; this update aligns with similar adjustments across AllianzIM's U.S. Large Cap Buffer10 and Buffer20 product series.
