Definition of Non-Maturity Deposits
Deposits provided by credit unions and banks that have no set maturity. These funds can be withdrawn at any time without any advance notice. In the case of credit unions, non-maturity deposits include:• Share Drafts• Regular Shares• Money Market Shares
3
Share Drafts
• Checking accounts• Some institutions offer dividend rates on share draft accounts and some
do not• Generally lower rates than regular shares and money market shares• Option to withdraw at any point in time• Additional services offered:
– Bill pay– Checks– ATMs
• Usually have longer average lives than other non-maturity share types
4
Regular Shares
• Saving accounts• Offered dividend rates are usually higher than share drafts but lower than
money market accounts• Limit on withdrawals• Limited check writing privileges • Considered slightly less liquid than share drafts• Generally minimum balance requirements• Usually shorter average life than share drafts but longer than money
market accounts
5
Money Market Shares
• Generally higher rates offered compared to share drafts and regular shares
• Less liquid than share drafts and regular shares but more liquid than certificates
• Limit on withdrawals• Higher minimum balance requirements• Depositors more sensitive to market interest rates• Lower average lives due to interest rate sensitivity
6
Non-Maturity Shares as a Funding Source
7
Advantages• Cheap source of funding• Popular products• Member loyalty• Cross selling opportunities• Ability to determine offered
rates• Insured by the NCUA
Disadvantages• Option to withdraw funds at any
time• Sensitive to changes in interest
rates• Marketing and servicing costs• Regulatory costs – Share
Insurance, BSA etc.
Non-maturity Share Assumptions for ALM• Re-pricing beta• Effective maturity• Decay• Surge
Members have continuous and unlimited options to increase or decreasebalances. These options may or may not correlate to market conditions.

Sources of Non-maturity Deposit AssumptionsHistorical studies of an institution’s past deposit behavior:• NERA (National Economic Research Associates) study• FDICIA 305• Par
9
NERA Study• NCUA commissioned study in 2001
• Items covered:– Comprehensive review of literature on valuing non-maturity deposits– Statistical study of credit union deposit behavior– Evaluation of various vendor methodologies– Recommendations for ALM modeling inputs– Implications and guidelines for the NCUA
• Study does not incorporate the effects of the historically low interest rates and the flight to deposits due to the recent financial crisis.
• Actual credit union historical experience is likely different than the published results.
10
FDICIA 305• Refers to distribution limits originally proposed in section 305 of the FDIC
Improvement Act of 1991 (FDICIA)• These guidelines were never implemented

Benefits of a Non-Maturity Deposit Study
• Determine institution specific historical member behavior• Effective maturities are usually calculated longer than the regulatory
studies• Ability to calculate account specific assumptions for special account
types such as high rate checking and high balance money market accounts
• Realistic view of projected interest expense and economic value of liabilities in various interest rate shock scenarios
• Allows for back-testing to evaluate assumptions

make in response to changes in market interest rates• Calculated with a linear regression that compares the change in

Correlation
• A statistical measure of how dividend rates and market interest rates move in relation to each other
• We test correlation between the movement in dividend rate pricing and 5 interest rate indices: 1 month LIBOR, 3 month LIBOR, 6 month LIBOR, 2 year Treasury, and Fed Funds.

Effective Maturity• Indicates when the last cash flow for an account type is projected to
occur• Derived from a second regression analysis modeling the spread
between the rate index and deposit rate versus the average balance for the account type
• Calculation of R-squared measures how well changes in average deposit balances are explained by changes in the spread of the deposit rate to the rate index

Financial Crisis Impact on Effective Maturity Calculation
• Due to the unprecedented financial crisis, non-maturity deposit balances have increased even though dividend rates were at historical lows
• As a result, longer effective maturities are usually calculated while analyzing non-maturity deposits
• Wilary Winn recommends using 50% to 75% of the calculated effective maturities for ALM modeling in a rising interest rate environment
18
Momentum• Rate of acceleration of account balances• Compares current account balance to historical trends• Derived from the results of the effective maturity calculation – Balances
are estimated given the current spread of deposit rate to risk free index• May indicate the presence of surge balances
19
Decay AssumptionsA decay rate analysis can be performed using one of two methods:
a) Account number method: This method begins with a set of accounts and balances. These accounts are then tracked in order to determine what happens to the balances over time. In the process, no new accounts are considered.
b) Origination date method: This method compares beginning and ending balances of all accounts by account type and also takes new accounts into consideration in order to determine a decay rate. Account numbers are generally not needed for this method.
In most cases, both methods will yield roughly the same results.

Decay Rates by Shock Scenario
Financial Crisis and Surge Deposits
• As a result of the recent financial crisis, financial institutions experienced non-maturity balances increasing even with dividend rates at historic lows
• Investors increased their preference for liquidity leading to a surge in deposits at financial institutions across the nation
• These Surge deposits are projected to migrate into alternative investments in other asset classes as market interest rates increase
• Surge deposits should be modeled with high decay rates and higher-than-average betas to forecast the outflow of these funds

Core Deposit Intangible• Underlying premise is that a rational buyer is willing to pay a premium to
obtain a group of core deposit accounts that are less expensive than the buyer’s marginal cost of funds
• Wilary Winn uses calculated betas, decay rates, and effective maturities in the CDI valuation process
• All-in-costs are estimated using the projected dividend rates paid and net costs to service non-maturity deposit accounts
• All-in-costs are then compared against the buyer’s marginal cost of funds (net borrowing costs) to determine the amount of cost/benefit
• This cost/benefit amount is then discounted in order to calculate the CDI

NERA Non Maturity Deposit Assumptions
CU Philosophy and Share Pricing
• Credit unions are member-owned and seek ways to maximize member benefit
• Member benefits can be provided by:– Above-market dividend rates– Affordable loan rates– Other products – mobile banking, drive-thru ATMs etc.
• Providing above-market dividend rates on non-maturity deposits is possible given the institution has the required level of capital to sustain these rates
29
Capital and Share Pricing
• Share pricing is based on a variety of factors including the level of capital
• Currently credit unions usually provide above market dividend rates, given the required level of capital to sustain these share prices
• The primary risk here is to maintain the current level of capital in an increasing interest rate environment
• These above-market dividend rates also need to be incorporated into the ALM process
30
Non-Maturity Deposit Studies
• Credit unions can analyze non-maturity deposit behavior using account level information or the 5300 call report data
• An account level analysis is more extensive and can be customized based on account type characteristics
• Important information may be missed while analyzing non-maturity deposit behavior using call report data
– Inability to analyze deposits by tier– Inability to calculate historical decay rates due to lack of information– Inability to segregate information based on different account characteristics on
accounts grouped within the same call report account type
31
Recommendations
• In the ALM modeling process, the equity position should be analyzed under three different scenarios:
– Institution specific non-maturity deposit assumptions– NERA/FIDICIA 305 non-maturity deposit assumptions– Non-maturity deposits at par
• Non-maturity deposit data should be analyzed over the last 10 years in order to include the effects of different interest rate environments
• Surge deposits should be identified and run-off faster than normal deposits
• 50% - 75% of calculated effective maturities should be used• Back-testing of non-maturity deposit assumptions
