Explanatory Note – settlement prices publication End-of-Day report
At the end of each business day, ICE Endex establishes settlement prices for the markets it
operates. These settlement prices are published as part of the End of Day Report, an
automatically derived report publishing the full curve of tradable contracts available at ICE
Endex. The settlement prices are used by the Clearing House, ICE Clear Europe Limited (ICE
Clear), to calculate margins for the relevant contracts.
Given their theoretical nature, these prices are considered less useful as a basis for supplying
intermediary services to non-professional clients (e.g. as a parameter in commercial delivery
contracts). A reasonable professional understanding of the price formation process on
wholesale energy markets is expected with anyone using the prices as published in the report.
The purpose of this note is to explain the methodology of establishing these settlement prices.
This is for information only, and on the condition that errors and/or omissions shall not be
made the basis for any claim, demand, or cause of action.
The settlement prices are established on the basis of the following steps:
1. Pricing
Window
2. Fallback
3. Arbitrage Free
Methodology
4. Forward
Curve
5. Preliminary
Publication
Settlement prices, established by means of the pricing window, are prices based on trades and
quotes fulfilling pre-defined prerequisite conditions (as detailed later in this document), from
ICE Endex trading platform leading to a higher transparency of the calculation input; while
settlement prices established by means of the fallback scenario are prices resulting from a
market assessment.
Settlement prices before their publication are displayed on the trading platform as preliminary
settlement prices to market parties, and subject to a 5 minute window for submitting remarks
on the curve level. Once the 5 minute window is closed the settlement prices will become final
and published accordingly.

1. Pricing Window Methodology
In general, the basic principle of establishing a pricing window means that settlement prices
will be determined by a combination of actual trades as well as firm orders on screen during a
pre-defined time period, which complies with the conditions as set per individual market.
These conditions include the following:

start- and end time of the pricing window;

minimum traded volume requirements;

minimum volume size of orders;

maximum settlement spread for combination of best bid-best ask orders;

cumulated minimal duration of valid best bid-best ask orders;

minimum numbers of distinctive market parties that supports the best order;

volume weighting of trades;

weighting factor between average trade price and average mid order price.
Orders from distinctive market parties are taken into account if the standard deviation of this
order is less than 0.20 of the best bid or best offer respectively. All orders during the pricing
window that are within the 0.20 standard deviation from the best order will be used for counting
how many distinct market parties are active per individual strip. Input from the pricing window
of the respective strip will be deemed as valid only if the required minimum number of
distinctive market parties is reached (e.g.: For Dutch Power Base load this parameter is set to
a minimum of 4 market parties).Further details on the parameters for the individual markets
can be found at http://www.theice.com.
Only transactions, bids, and offers in the order book of the ICE Endex Futures Exchange are
taken into account for calculating the prices; block trades, EFPs and EFSs reported by means
of the Block Trade Facility are disregarded. Trades which have been cancelled during the
pricing window will not be included in the calculations either. As part of its responsibilities as
operator of a regulated market, ICE Endex will monitor market developments during the pricing
window and will not consider individual prices or orders in case they are not in line with the
actual conditions of the market. In case of fast moving market conditions, the applicable
maximum settlement spreads will double.

In theory, 4 different scenarios could occur during the pricing window. These scenarios are
described below and the examples are valid for a pricing session for Dutch Power Base Load
contracts (single strip such as a Monthly strip).

2. Fallback Methodology
In the event there are insufficient valid quotes and transactions during the pricing window
Market Supervision will apply an alternative methodology in the following ranking order of
preference:
(1) Implied Price;
If applicable, the implied price of the missing strip will be used as preliminary
settlement price.
(2) Trading activity during the day;
The market activities (quotes, trades and market trend) during the day will be used as
input.
(3) External sources;
The latest market activities (quotes, trade and market trend) as available by external
data provider(s) will be used as input.
(4) Correlated Market as proxy;
The market trend of the market of which price formation in the past has shown to be
most heavily correlated will be used as input.
(5) Price assessment;
This is a discretionary assessment combining multiple sources (from market parties,
market trend and/or previous settlement) of input.
3. Basics of the arbitrage free methodology
Since the settlement prices are established by ICE Endex for margin purposes of the Clearing
House, in some circumstances the settlement prices, as determined by either the pricing
window or alternative sources, may need to be adjusted in order to be free of arbitrage. These
conditions are required by the Clearing House in order to have a secure and correct margining
process. Contracts with overlapping delivery periods will need to be priced in line. With

reference to possible arbitrage opportunities, the following contracts are directly linked to each
other:

Calendar vs. Quarters;

Calendar vs. Months;

Season vs. Quarters (in case of Gas futures);

Season vs. Months (in case of Gas futures);

Quarter vs. Months.
ICE Endex will apply an arbitrage free methodology by means of calculating a weighted
average price based on each contract underlying value. If there are prices available which are
determined by the pricing window, these prices prevail over the prices derived from the fallback
procedure when applying the arbitrage free methodology.
As a further explanation, the following scenario’s and results are provided for information:
- Scenario 1:
only 1 price is from the fallback, while all others are from the pricing window. In
this case, the price from the fallback will be the implied price;
- Scenario 2:
more than 2 prices are from the fallback, while the others are from the pricing
window. In this case, all the prices from the fallback will have an equal
arbitrage correction;
- Scenario 3:
all prices are from the fallback. In this case, all the prices will have an equal
arbitrage correction;
- Scenario 4:
all prices are from the pricing window. In this case, all prices will have an equal
arbitrage correction. This is the only scenario whereas prices from pricing
window are adjusted.
Scenario 1:
April, May and June are set by the pricing window while Q2 is missing, the price for the Q2
contract will be the implied price:

In exceptional cases there will be a possibility of overlapping arbitrage opportunities.
For these specific cases, a priority order has been defined as follows:
Round 1: Months vs. Quarter;
Round 2: Quarters vs. Calendar;
Round 3: Quarters vs. Season.
Each round is executed in a consecutive order, for which the outputs of the preceding round
are fixed and no longer adjustable by succeeding rounds. The arbitrage free prices will be used
as input for the calculation of the full curve, providing settlement prices for all contracts
tradable at ICE Endex.

4. Forward Curve
The size of the curve is determined by the amount of calendar contracts available for trading in
a market, the December contract always being the last tradable contract and therefore the last
contract month of the curve. For example, ICE Endex offers 5 Calendars for trading in TTF
Natural Gas. In January, the forward curve will be composed of 59 months (taking into account
that the January contract already expired in December), while in October the forward curve will
be composed of 50 months.
The cascading of the settlement prices into monthly settlement prices is done by building a
forward curve in monthly granularity, excluding the cost to carry, with specific load factors for
shaping the curve, whereby the strip closest to its monthly cascading underlying month has the
priority. Therefore the following cascading priority order is used for building the curve:
(1) Quarter to month;
(2) Season to month;
(3) Calendar to month.
The cascading process is to ensure that the forward curve retains the respective inter-strip
arbitrage free value.
Each round is executed in a consecutive order, for which the outputs of the preceding round
are fixed and no longer adjustable by succeeding rounds. The arbitrage free prices will be used
as input for the calculation of the full curve, providing settlement prices for all contracts
tradable at ICE Endex.
5. Preliminary publication of settlement prices
The curve is supplied to the market as preliminary settlement first, through the trading platform.
As from this moment, the members have a 5 minute window of opportunity to give remarks and
comments on the curve. If no comments or remarks are received in this 5 minute window, the
curve will be final. If comments were received that were considered valid and Market
Supervision has decided to amend the preliminary settlement, the new settlement prices will
again be published on the trading platform with a 5-minute window opportunity to give remarks.
If no comments or remarks are received in this second 5 minute window, the curve will be set
on final. If however in this second 5 minute window comments were received that were valid
and Market Supervision had to amend the settlement, the new settlement will directly become
final.

To allow for timely processing, comments and remarks on the preliminary settlement prices
must be addressed directly to the Market Supervision team in Amsterdam reachable at +31 20
305 5140.
6. Publication of settlement prices
After ICE Endex has established a settlement price for all contracts (in strips of months), the
settlement prices are automatically published in the End of Day Report at the ICE Report
Centre, www.theice.com. The settlement prices are used by the ICE Clear to calculate margins
for the relevant contracts.
Given their theoretical nature, these prices are considered less useful as a basis for supplying
intermediary services to non-professional clients (e.g. as parameter in commercial delivery
contracts). A reasonable professional understanding of the price formation process on
wholesale energy markets is expected with anyone using the prices as published in the report.
