We measure the fair value of our financial assets and
liabilities in accordance with ASC Topic 820. These financial
assets and liabilities primarily consist of
<i>(i) </i>derivatives recorded on our balance sheet under
ASC Topic 815, <i>(ii) </i>weather derivatives and
<i>(iii) </i>long-term debt outstanding that are required
to be disclosed at fair value. Under ASC Topic 820, fair value
is defined as the exit price, representing the amount that would
be received in the sale of an asset or paid to transfer a
liability in an orderly transaction
between market participants at the measurement date. To value
our financial instruments, we use market data or assumptions
that market participants would use in pricing the asset or
liability, including assumptions about credit risk (both our own
credit risk and the counterparty’s credit risk) and the
risks inherent in the inputs to our valuation technique, the
income approach.

We enter into derivative contracts in the
<font style="white-space: nowrap">over-the-counter</font>
(OTC) wholesale and retail markets. These markets are the
principal markets for the respective wholesale and retail
contracts. We have determined that all of our existing
counterparties and others who have participated in energy
transactions at our delivery points are the relevant market
participants. These participants have access to the same market
data as WGL Holdings. We value our derivative contracts based on
an “in-exchange” premise and valuations are generally
based on pricing service data or indicative broker quotes
depending on the market location. We measure the net credit
exposure at a counterparty level where the right to set-off
exists. The net exposure is determined using the
<font style="white-space: nowrap">mark-to-market</font>
exposure adjusted for collateral, letters of credit and parent
guarantees. We use published default rates from
Standard & Poor’s Ratings Services and
Moody’s Investors Service as inputs for the determination
of credit adjustments.

ASC Topic 820 establishes a fair value hierarchy that
prioritizes the inputs used to measure fair value. The hierarchy
gives the highest priority to unadjusted quoted prices in active
markets for identical assets or liabilities and the lowest
priority to unobservable inputs. The three levels of the fair
value hierarchy under ASC Topic 820 are described below:

<div align="left" style="margin-left: 3%; margin-right: 0%; text-indent: 3%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent">
<b><i>Level 1.</i></b>  Level 1 of the fair
value hierarchy consists of assets or liabilities that are
valued using observable inputs based upon unadjusted quoted
prices in active markets for identical assets or liabilities at
the reporting date. Level 1 assets and liabilities
primarily include exchange traded derivatives and securities. At
September 30, 2010, we do not have any financial assets or
liabilities in this category.

<div align="left" style="margin-left: 3%; margin-right: 0%; text-indent: 3%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent">
<b><i>Level 2.</i></b>  Level 2 of the fair
value hierarchy consists of assets or liabilities that are
valued using directly or indirectly observable inputs that are
corroborated with market data or based on exchange traded market
data. Level 2 includes fair values based on
industry-standard valuation techniques that consider various
assumptions including: <i>(i) </i>quoted forward prices,
including the use of mid-market pricing within a bid/ask spread;
<i>(ii) </i>discount rates; <i>(iii) </i> implied
volatility and <i>(iv) </i>other economic factors.
Substantially all of these assumptions are observable throughout
the full term of the instrument, can be derived from observable
data or are supported by observable levels at which transactions
are executed in the relevant market. At September 30, 2010,
Level 2 financial assets and liabilities included
non-exchange traded energy-related derivatives such as financial
swaps and options and physical forward contracts for deliveries
at active market locations. Additionally, at September 30,
2010, Level 2 financial instruments included interest rate
swaps. At September 30, 2009, Level 2 financial assets
and liabilities included a weather derivative as well as
interest rate swaps using observable data.

<b><i>Level 3.</i></b>  Level 3 of the fair
value hierarchy consists of assets or liabilities that are
valued using significant unobservable inputs at the reporting
date. These unobservable assumptions reflect our assumptions
about estimates that market participants would use in pricing
the asset or liability, including historical volatility and
pricing data when delivery is to inactive market locations.
These inputs may be used with industry standard valuation
methodologies that result in our best estimate of fair value for
the assets or liabilities at the reporting date. At
September 30, 2010, OTC derivative assets and liabilities
in this category included: <i>(i) </i>physical contracts
valued with significant basis adjustments to observable market
data when delivery is to inactive market locations;
<i>(ii) </i>long-dated positions where observable pricing
is not available over the life of the contract;
<i>(iii) </i>contracts valued using historical volatility
assumptions and <i>(iv) </i>valuations using indicative
broker quotes for inactive market locations. Additionally, at
September 30, 2010, Level 3 financial instruments
included weather derivatives valued using unobservable market
data.

The following tables set forth financial instruments recorded at
fair value as of September 30, 2010 and September 30,
2009, respectively. A financial instrument’s classification
within the fair value hierarchy is based on the lowest level of
any input that is
significant to the fair value measurement. Our assessment of the
significance of a particular input to the fair value measurement
requires judgment, and may affect the valuation of fair value
assets and liabilities and their placement within the fair value
hierarchy.

Transfers between different levels of the fair value hierarchy
may occur based on the level of observable inputs used to value
the instruments from period to period. It is our policy to show
both transfers into and out of the different levels of the fair
value hierarchy at the fair value as of the beginning of the
reporting period. During the year ended September 30, 2010,
a $2.0 million fair value liability related to Washington
Gas’s weather derivative was transferred from Level 2
to Level 3 in the fair value hierarchy and a
$0.9 million liability was transferred from Level 3 to
Level 2 related to this derivative. There were no other
transfers during the reported periods.
