23.2 Fees vs. Compensating Balances: Strategic Analysis

Fees vs. Compensating Balances: Strategic Analysis

A government must decide whether to compensate the bank via direct fee payment (paying invoice charges out of an appropriated operating budget line item) or through compensating balances (leaving sufficient collected cash in the bank to generate earnings credits that reduce the net service charges to zero):

• When prevailing short-term market interest rates (e.g., U.S. Treasury bills or LGIP yields) are higher than the bank's offered ECR, the government should maintain minimum balances, sweep all surplus cash into high-yielding market investments, and pay banking fees directly via cash invoices.
• When the bank's ECR exceeds net short-term investment yields (often occurring in falling or near-zero interest rate environments, or when banks offer promotional soft-dollar credits), maintaining compensating balances to offset service charges is mathematically superior.
• Tax and Legal Caution: Under IRS arbitrage rebate regulations (IRC § 148), earnings credits generated on the deposit of tax-exempt bond proceeds may be treated as gross investment earnings subject to federal arbitrage yield restrictions.

Bank Selection, Competitive Procurement & Institutional Evaluation

The selection of a municipal depository is a critical fiduciary transaction. The GFOA recommends that governments competitively procure banking services through a structured Request for Proposals (RFP) process at least every three to five years.

The Competitive RFP Process

Awarding banking contracts based on political favoritism, informal relationships, or inertia violates public procurement standards. A competitive banking RFP must include:

• Detailed multi-year transaction volumes (average monthly lockbox items, ACH volumes, outgoing wires, cash deposits, and daily collected balances).
• Rigorous technical requirements (compatibility with the government's Enterprise Resource Planning [ERP] system, automated positive pay integration, electronic statements, and daily reporting APIs).
• Clear collateralization compliance terms in strict conformance with state statutory mandates.
• Unbundled, fixed fee pricing schedules across all standard AFP service line items for the entire contract term (including renewal option periods).

Evaluating Financial Counterparty Stability: CAMELS and Capital Ratios

Public entities must perform ongoing credit and solvency due diligence on all depository institutions. Financial stability is evaluated using:

• Federal Regulatory CAMELS Ratings: Supervisory ratings assigned by bank regulators (Federal Reserve, OCC, FDIC) evaluating Capital adequacy, Asset quality, Management capability, Earnings performance, Liquidity, and Sensitivity to market risk (scores range from 1 [strongest] to 5 [critically deficient]).
• Regulatory Capital Adequacy Ratios: Ensuring the institution qualifies as "Well-Capitalized" under federal prompt corrective action regulations (Tier 1 Risk-Based Capital Ratio of at least 8.0%, Total Risk-Based Capital of at least 10.0%, and Tier 1 Leverage Ratio of at least 5.0%).
• Long-Term Credit Ratings: Evaluating senior debt ratings from Nationally Recognized Statistical Rating Organizations (NRSROs) like Moody's, S&P, and Fitch.

Community Reinvestment Act (CRA) Performance

State and local governments frequently enact statutory policies requiring public depositories to maintain a satisfactory record of supporting the local civic community. Under the federal Community Reinvestment Act of 1977 (CRA), federal banking regulators assess an institution's record of helping to meet the credit needs of its entire community, including low- and moderate-income neighborhoods. Most public procurement codes require bidding banks to submit their official federal CRA rating, establishing a minimum threshold of "Outstanding" or "Satisfactory" to be eligible to hold public deposits.

Internal Controls Over Cash and Fraud Prevention

Because cash and electronic payment releases possess maximum liquidity, they represent the single highest exposure area for employee defalcation, external theft, and cyber-fraud. Robust internal control frameworks—grounded in the COSO Internal Control - Integrated Framework and the GAO Green Book—are legally mandated.

Strict Segregation of Duties

No single public employee should possess the authority, capability, or access to execute a cash transaction from initiation to final reconciliation. Operating controls must enforce a strict four-way separation among:

1. Asset Custody: Physical handling of currency, paper checks, endorsement stamps, check stock, or signature plates (e.g., central cashiers, mailroom intake personnel).
2. Authorization: Approving purchase orders, certifying receiving reports, and signing disbursement vouchers or releasing electronic payment batches (e.g., purchasing agents, department heads, finance directors).
3. Accounting and Recording: Entering vendor invoices, posting journal entries, maintaining general ledger accounts, and updating accounts receivable/payable files (e.g., accounting clerks, bookkeepers).
4. Reconciliation: Verifying bank statement balances against general ledger control accounts (must be performed by independent personnel with no access to cash custody, check signing, or voucher creation).

Mandatory Monthly Bank Reconciliations

Independent monthly bank reconciliations are an indispensable detective control. Standard financial administration requires:

• The bank statement must be delivered directly (unopened, or via secure direct read-only electronic download) to an independent reconciliation staff member who has no custody, disbursement, or ledger posting duties.
• Reconciliations must be completed within 30 days of monthly statement closing.
• All reconciling items—such as deposits in transit, outstanding checks, unrecorded bank service charges, interest earned, or electronic NSF return items—must be investigated, documented, and posted to the general ledger.
• Reconciliations must be formally reviewed, signed, and dated by a supervisory finance official (e.g., Comptroller or Internal Audit Director).

Positive Pay Systems and Check Fraud Prevention

Despite the growth of electronic payments, paper checks remain highly susceptible to check washing, forged signatures, and fraudulent counterfeiting. Modern governments mandate Positive Pay services across all disbursement and payroll accounts:

• Standard Positive Pay: Every time the government issues a check run, the finance system automatically generates an encrypted electronic file transmitted to the bank detailing the exact check number, issue date, and dollar amount of each issued check. When checks are presented for payment through the banking system, the bank matches them against this issuance list. Any check with an unlisted number or mismatched dollar amount is flagged as an "exception item" and held. The government must log in and explicitly approve or reject the item by a daily deadline; unapproved items are returned unpaid.
• Payee Positive Pay: Enhances standard positive pay by adding the payee name to the matching criteria. The bank's optical scanning systems read the physical payee line on the presented check and compare it to the issue file, neutralizing sophisticated chemical check-washing schemes that alter the payee name while preserving the original check number and dollar amount.
• Reverse Positive Pay: A weaker alternative where the bank provides the entity with a daily list of all checks presented for clearing, and the entity manually inspects the list against its internal check register to instruct the bank on which items to reject. Because it relies on manual daily human intervention, it is significantly inferior to automated Payee Positive Pay.

Wire Transfer Dual-Control Authorization

Wire transfers (Fedwire) result in immediate, irrevocable, same-day cash transfers. To prevent catastrophic theft or Business Email Compromise (BEC) wire fraud, internal controls require:

• Dual-Control Authorization: One authorized individual creates or initiates the electronic wire instruction in the bank's portal, while a completely separate authorized supervisory official reviews supporting vendor documentation and independently releases the wire using unique hardware cryptographic tokens or multi-factor authentication.
• Out-of-Band Callbacks: Mandatory verbal telephone verification to a known, established vendor contact (using an independently verified phone number from internal vendor master records, never the phone number listed on an emailed invoice or wire change request) prior to executing any changes to vendor bank routing numbers or account details.

Statutory Payment Standards: Prompt Payment Mandates

Public entities must comply with statutory payment mandates that balance cash conservation against fairness to commercial contractors and vendors.

The Federal Prompt Payment Act (31 U.S.C. § 3901 et seq.)

The federal Prompt Payment Act (implemented in 5 CFR Part 1315) governs payments made by federal executive agencies to commercial vendors for property and services. Its core provisions include:

• The 30-Day Baseline Rule: Federal agencies must disburse payment to a contractor within 30 calendar days after the receipt of a proper, certified invoice, or 30 days after the physical receipt and acceptance of the supplies or services, whichever is later.
• Accelerated Payment Schedules: Specialized contracts establish shortened statutory payment windows (e.g., 14 calendar days for construction contracts and invoices for perishable agricultural commodities, dairy, and poultry products).
• Mandatory Interest Penalties: If an agency fails to make payment by the required statutory due date, it must pay an automatic interest penalty to the contractor without the contractor needing to request or invoice for it. The interest penalty rate is established semi-annually by the Secretary of the Treasury under Section 12 of the Contract Disputes Act (published in the Federal Register by the Bureau of the Fiscal Service).
• Grace Periods Prohibited: The Prompt Payment Act strictly prohibits agencies from taking advantage of unauthorized informal "grace periods"; interest begins accruing on the calendar day immediately following the payment due date and compounds monthly until final disbursement.

Economic Analysis of Early Payment Discounts

Vendors frequently offer early payment cash discounts to accelerate their own cash collections (e.g., 2/10, net 30: the government may deduct a 2% discount from the gross invoice total if paid within 10 calendar days; otherwise, the full invoice total is due within 30 days).

Under federal Prompt Payment regulations and sound municipal treasury practice, a government may take an early payment discount only when it is economically advantageous. Financial managers evaluate this using the Annualized Effective Discount Rate formula:

$\text{Annualized Discount Rate} = \left( \frac{\text{Discount \%}}{100\% - \text{Discount \%}} \right) \times \left( \frac{360 \text{ or } 365}{\text{Total Days} - \text{Discount Period Days}} \right)$

For standard 2/10, net 30 terms:

$\text{Annualized Discount Rate} = \left( \frac{2}{98} \right) \times \left( \frac{360}{30 - 10} \right) = 0.020408 \times 18 = 36.74\%$

• Because an annualized yield of 36.74% vastly exceeds prevailing short-term municipal investment yields (e.g., 2.0% to 5.0% on U.S. Treasury bills or LGIPs), the government should always capture the discount by executing payment on exactly the 10th day.
• If the government pays on Day 10, it effectively earns a 36.74% annualized return on its liquidity.
• However, if the government pays on Day 25 without taking the discount, it surrenders the 2% savings while gaining only 5 days of marginal overnight investment interest—an unacceptable operational failure.

State Prompt Payment Equivalents

Virtually all 50 states have enacted state-level Prompt Payment Acts modeled after the federal statute. These state acts typically establish mandatory payment timelines (commonly 30 or 45 calendar days following receipt of an undisputed invoice), prescribe statutory late-payment interest penalties (often ranging from 1.0% per month [12% annually] to prevailing prime rates), and provide specific dispute-resolution mechanisms allowing agencies to toll (suspend) the statutory clock only when formal written notice of invoice defects is delivered to the vendor within 10 to 15 days.

Practical Public Finance Scenario: Municipal Treasury Cash Optimization Audit

Scenario: The City of Crestview (population 185,000) maintains an annual operating budget of $240,000,000. An internal operational review of the city treasury by the newly appointed Finance Director reveals several cash management inefficiencies:

1. Tax collections and utility bills are remitted to physical cashier windows at City Hall, where paper checks sit in unlocked desk drawers for up to four business days before staff prepare physical deposit slips and walk them to the local bank branch.
2. The city maintains seven separate operating checking accounts across three banks, each holding an average uninvested ledger balance of $750,000 to "prevent potential check overdrafts."
3. Standard checking account service charges total $14,000 per month, offset only by an ECR of 0.85% applied to uncollected balances, while the state Local Government Investment Pool (LGIP) yields 4.80%.
4. Invoices offering 2/10, net 30 terms are routinely paid on Day 38 due to slow interdepartmental paper approvals, incurring state statutory late interest penalties of 1% per month while missing early discounts.

Professional Treasury Corrective Action Plan

1. Implement Retail Lockbox and Remote Deposit Capture (RDC):
   • Divert all utility bills and property tax remittances to a centralized retail bank lockbox utilizing OCR scannable coupons, collapsing 4 days of mail/processing float into same-day electronic ledger availability.
   • Install Check 21 RDC scanners at City Hall service counters for immediate digital scanning and transmission of in-person checks, securing same-day collected balances and eliminating transit theft risk.
2. Restructure Banking into Master Concentration and Zero-Balance Accounts (ZBAs):
   • Close the seven fragmented checking accounts and consolidate all liquidity into a single Master Concentration Account at a single primary depository.
   • Establish subsidiary ZBAs for Accounts Payable and Payroll. The $5,250,000 in idle cash ($750,000 × 7) previously stranded as overdraft buffers is liberated and swept into the state LGIP.
   • At the state LGIP yield of 4.80%, deploying this $5,250,000 generates $252,000 in new annual investment income for the city.
3. Account Analysis Optimization (Pay Fees Directly):
   • The city's depository offers an ECR of only 0.85%, while external liquid LGIP yields are 4.80% (a spread of 395 basis points).
   • The Finance Director should minimize compensating balances to the bare operational clearing minimum, sweep all surplus cash into the 4.80% LGIP, and pay the $14,000 monthly banking charges directly via cash warrants. The earnings on the swept funds far exceed the banking fee expenses.
4. Automate Accounts Payable Workflow to Capture Discounts and Eliminate Penalties:
   • Deploy an electronic workflow routing invoices for approval within 48 hours.
   • On vendor invoices offering 2/10, net 30, automate disbursement scheduling for Day 10 to capture the 36.74% annualized return, while scheduling non-discount invoices for Day 30 to comply with Prompt Payment rules without paying early.
