Credit Policy Overview

2

www.spp.org

• The purpose of the Credit Policy is to establish a transparent and non-discriminatory process for extending secured and unsecured credit.

• The policy was created by SPP’s Credit Task Force and approved by the Finance Committee and Board of Directors.

SPP Credit Policy – Executive Summary

3

www.spp.org


• Scoring models for credit customers are based on common financial characteristics and designed for specific industry groups.

• The score produced by the model translates into an Unsecured Credit Allowance for the customer.

• Customers that do not qualify for unsecured credit or desire credit above an unsecured allocation may post financial security with SPP.

4

www.spp.org

• Each day, SPP will1.determine the Total Potential Exposure (TPE) of

each credit customer and2.compare the TPE of each credit customer is

compared to that customer’s Total Credit Limit (the sum of unsecured and secured credit allocations).

• If TPE exceeds the Total Credit Limit, the customer must provide financial security to SPP in the amount of the difference.


5

www.spp.org

• Events of Default by a credit customer place SPP at a higher risk of loss and include the following:

1. Failure to pay invoices in full when due.2. Failure to cure a TPE violation.3. Failure to provide requested information in a

timely manner.4. Bankruptcy filing.

• Remedies available to SPP for uncured defaults include suspension of all unsecured credit and termination of service (after FERC approval).

Credit Scoring

www.spp.org

• Qualitative Factors considered in scoring include:– Ability to set rates without regulatory approval– Number and composition of members or customers– Exposure to energy price risk for load served– Rating agency ratings assigned to unsecured debt– Tenure and quality of management– Terms of wholesale power contracts, if any– Risk management practices– Payment record with SPP, if any– Other non-financial measures of creditworthiness

• An overall score on a scale of 1 – 6 is used (1 is the highest).

Credit Scoring Methodology *

* See Credit Policy Articles 4.2.1, 4.2.2, and 4.2.3

• The credit evaluation performed incorporates qualitative and quantitative elements. The two are then weighted as reflected below, resulting in a total Composite Score.

• Maximum Unsecured Credit Limit under the SPP Credit Policy is $25,000,000.• Minimum Unsecured Credit Limit for a Not-For-Profit is $250,000.

* See Credit Policy Article 4.3

Determining the Unsecured Credit Limit *

• The Composite Score is the sum of weighted Qualitative and Quantitative scores.• Using the final Composite Score and the entity type, the customer’s tangible net

worth is multiplied by the appropriate percentage to determine the Unsecured Credit Allowance.

Total Potential Exposure

11

www.spp.org

• The formula for determining Total Potential Exposure is TPE = TSPE + ME

– TSPE = Transmission Service Potential Exposure– ME = Market (Energy Imbalance) Exposure

• The formula for determining Transmission Service Potential Exposure is TSPE = ITSC + CTSC + METE

– ITSC = Invoiced but unpaid service– CTSC = Service taken but not yet invoiced– METE = Estimate of future charges based on

historical usage for the remainder of the 50 day exposure window

* See Credit Policy Articles 5.1 and 5.2

Calculating Total Potential Exposure *

12

www.spp.org

• The formula for determining Market (Energy Imbalance) Exposure is ME = IMTSC + CMSC + MEME

– IMSC = Invoiced but unpaid service– CMSC = Service taken but not yet invoiced– MEME = Estimate of future charges based on

historical usage

Example of TPE Calculation *

• Based on current day of June 13, 2010.

• Assumptions:– TSPE

▫ May invoice amount of $8,500 is outstanding.▫ Amount of METE charges from end of CTSC to end of

exposure window (7 days) is $3,200.▫ Highest Network Service invoice over last 12 months is

$3,000 in September (30 day month).– ME

▫ Previous weekly invoice remains outstanding.▫ Average daily settlement activity for last 365 days is $700.▫ Average daily settlement activity for last 7 days is $600.

Short Payments and Uplift

28

www.spp.org

• Covered in Section V of Attachment L of the SPP Tariff.

• Terms as defined in Attachment L:– Unpaid Obligation – An unpaid past due amount of an

invoice pursuant to Section 7 of the Tariff or for Market Services for which SPP does not reasonably expect payment in full.

– Uncollectible Obligation – An Unpaid Obligation that has not been paid within ninety (90) days after SPP declared an invoice an Unpaid Obligation.

• Once an invoice is determined to be a Uncollectible Obligation, the dollar amount of this invoice is allocated among all the participants in the market during that week based on their share of the absolute value of the total invoices.

Short Payments – Background

29

www.spp.org

• The assumptions are:– In this invoice cycle, there are five participants in the market.– Three participants have funds that are due to be paid to SPP.– Two have credit balances and are owed money by SPP.– On the invoice due date, one MP fails to pay and is in default.

Short Payments – Hypothetical Situation

30

www.spp.org

• Using the data in the previous example, the following transactions are made:

• The net effect is the reallocation of the unpaid amount from only those that were due money to all participants in the market that week. SPP does not collect any funds above the original unpaid invoice.
