What Excess Cash management Means for Your Organization
Excess cash is the portion of your organization’s balance that sits beyond near-term operating needs, payroll, planned disbursements, and a reasonable contingency buffer. That cash may not be needed today, but it still has an important job: remain protected, stay accessible, and earn a competitive return while it is waiting to be used.
When large balances remain concentrated in a single bank account, two issues can emerge. First, idle cash may earn less than it could elsewhere, and when inflation outpaces the rate earned, its purchasing power shrinks. Second, balances above the standard $250,000 FDIC or NCUA insurance limit (per depositor, per insured institution, per ownership category) may be uninsured at that institution.
AMMA™ gives organizations a way to address both challenges without opening and managing numerous bank accounts independently. Through one ADM relationship, deposits can be distributed across participating financial institutions while clients maintain centralized visibility and access.
A Three-Step Framework for Managing Cash
Most finance teams approach cash management in three steps:
Calculate Your Operating Baseline
Forecast operating expenses, payroll, and planned disbursements, then add a contingency buffer. Cash above that baseline is excess cash.
Match Cash to Its Time Horizon
Cash you may need within days belongs in a liquid option with next-day access. Cash you won’t need for months may suit a longer-term option.
Reduce Concentration Risk
Confirm how much of each balance is insured at each institution, and diversify any amount above insurance limits.

How AMMA™ Solves Business Money Market Account Limitations
AMMA™ is ADM’s liquid excess cash management solution. Instead of relying on a single financial institution, ADM uses its network of more than 400 banking and credit union partners to help organizations diversify eligible deposits, maintain liquidity, and access competitive rates.
A typical single-bank business money market account caps insured coverage at $250,000 per depositor, per ownership category, and often reserves its best rates for seven-figure balance tiers. For organizations that have outgrown a standard business savings account, AMMA™ offers a different structure: one account that places funds across many insured institutions, so large balances can stay protected and liquid without opening new bank relationships.
Extended FDIC & NCUA Protection Across a Bank Network
Standard federal deposit insurance applies up to applicable limits at each insured financial institution. Organizations with larger balances can exceed those limits quickly when cash is concentrated at one bank or credit union. ADM helps distribute eligible deposits across participating institutions so clients can access extended FDIC or NCUA insurance coverage without independently opening and managing dozens of separate relationships. Through one ADM relationship, eligible organizations can access more than $75 million in combined FDIC/NCUA coverage, compared with $250,000 at a single bank or credit union.
Nationally Competitive Business Money Market Account Rates
Business savings and money market account rates can vary widely by institution, balance tier, and market conditions. Because ADM works with a network of more than 400 banks and credit unions, clients can access rates that may not be available to them through a single institution, without negotiating balance tiers bank by bank. Additionally, ADM’s patent-pending technology monitors opportunities across the financial institution network and can rebalance deposits to keep returns competitive, reducing the need for finance teams to manually shop rates or move funds themselves.
One Account, One Portal, One Statement
Rather than juggling multiple logins, statements, signer updates, and tax documents, clients manage their ADM relationship through one secure portal. Consolidated reporting provides visibility into balances and where funds are held, helping finance teams simplify oversight and month-end reconciliation. Clients receive one monthly statement and 1099-INT.
Keep Liquidity While Your Cash Works Harder
Cash should not become inaccessible simply because it is earning more. ADM’s liquid account structure is designed to provide next-day liquidity, giving organizations access to funds when operating needs, projects, or unexpected expenses arise.
ADM’s approach follows a clear priority order: safety first, liquidity second, operational simplicity third, and yield fourth. Technology and active rate monitoring support that framework by helping keep funds appropriately positioned without requiring clients to track hundreds of institutions themselves.

How does AMMA™ provide extended FDIC and NCUA protection?
ADM distributes deposits across participating FDIC-insured banks and NCUA-insured credit unions within its network.
