How a $4M position turns into $3.2M in cash.
Lets say you hold $4M in a single stock (though our minimums start at ~$1M). You want to bridge to a new opportunity today. A Collar Advance turns that position into liquidity without a huge tax bill.

How? We place a synthetic "collar" on your stock (a floor and a cap), ensuring the value never falls below the floor. This defined risk profile allows the bank to lend a higher amount against your asset safely.

Because the bank’s risk is contained, you can lock in a fixed rate for the term. The rates can be as low as 3.7%, which is significantly lower than traditional margin loans, and comes without the risk of margin calls.

Instead of paying taxes today, you defer them until the contract matures. At the end of the term, you can settle the advance using your stock or cash, effectively bridging you to a future liquidity event.

Borrow at rates lower than the alternatives
Rates Disclosure – Information is current as of 12/10/25
Rates shown are illustrative, may not be available to all clients, and depend on collateral quality, loan term, issuer concentration, and market conditions. Examples were sourced from select industry participants, do not represent a comprehensive survey of the market, and will not be updated.
Stock-based lines of credit and margin loans are generally liquid, while collar advances are illiquid and typically have terms of two to five years. A collar advance involves derivative contracts that limit both downside risk and upside participation. Investors may forgo gains above the cap and may be required to deliver shares or cash at maturity depending on market performance. Margin loans and stock-based lines of credit do not limit upside participation; however, rates are variable and positions are subject to margin calls.
Your rate is locked for the entire term. Unlike margin loans that float with market rates, your cost never increases—even if the Fed hikes
rates.
There are no monthly bills to pay. Interest is capitalized at the beginning of term, and you receive a lump-sum payment post interest and execution expenses.
This structure was only available for clients with tens of millions in a single stock. We’ve brought the entry point down to ~$1M, giving you the same tools used by the ultra-wealthy.
How Collar Advance works
Collar Advance is a way to get upfront cash in exchange for a contract to sell your stock at a later date. The contract can be structured for 2–5 years, and you may be able to roll it forward until you’re ready to sell.

Define your protection
You select a downside "floor" to define how much protection you want. Based on market conditions, a corresponding upside "cap" is set. This creates a safe range for your stock value. Because the floor protects the collateral, you will never face a margin call, even if the stock crashes.
For example: With a 2-year 80% – 160% collar, you are protected against any drop below 80% (limiting your max loss to 20%). In exchange, you participate in all upside growth up to 160% for the next two years.
If your holding goes down in value, you won’t face a margin call.
Unlock maximum liquidity
Because your position is protected, we can advance significantly more cash than a standard bank loan. In this case, up to 80% of the stock value, minus interest fees and expenses.
