Calamos Tax-Aware Collateral ETF is an actively managed ETF that seeks to achieve its investment objective through multiple combinations of synthetic long and short exchange-listed options positions, collectively referred to herein as a Box Spread. A Box Spread is an offsetting set of options, which may include FLEX Options. Box Spreads consist of a synthetic long position coupled with an offsetting synthetic short position through a combination of options contracts on a reference asset at the same expiration date. The reference asset in the context of the Fund's Box Spreads will be the S&P 500 ETF ("SPY"). The Fund may structure its Box Spread using a four-options-contracts approach, a three-options-contracts approach, or a two-options-contracts approach. Under a four-options-contracts approach, the synthetic long position consists of (i) buying a call option and (ii) selling a put option, each on the same reference asset and each with the same strike price and expiration date. The synthetic short position consists of (i) buying a put option and (ii) selling a call option, each on the same reference asset and each with the same expiration date as the synthetic long but with a different strike price from the synthetic long position.
