CEO Perspective
Natural Gas: Significant Advantages Across
All Sectors
If inefficient coal plants in the US were to retire,
7.3 Bcf/d of natural gas would be required
By 2020, NA fertilizer projects could increase
production by 24.7 million metric tons per year requiring
an incremental 1.2 Bcf/d of natural gas demand
NA methanol production is poised to increase by
13 million metric tons per year requiring 1.4 Bcf/d
of natural gas
If half of the Northeast US fuel oil use was
displaced by natural gas, it would equate to roughly
800 MMcf/d of incremental natural gas

Notes: 1 Near-term tax rates are lower than longer-term rates due to accelerated depreciation and deductions related to our
investment in ACMP. A 2014 tax Net Operating Loss, due to bonus depreciation, will yield a carryback refund from 2012 and a
carryforward reducing taxes through 2017. The average tax rate for 2018–2019 is expected to be approximately 4%, which
represents a blended rate on WPZ distributions, WMB NGL Petchem earnings, and corporate interest expense as well other tax
items impacting the WMB corporate entity. 2 WMB Cash Flow Available for Dividends / WMB Expected Dividends Paid.

Appendix
Recently Proposed IRS Regulations on MLP
Qualified Income
Update
>  On May 5, 2015, the Treasury Department issued
proposed regulations providing guidance on the
meaning of “qualified income” from activities related to
natural resources under Code section 7704(d)(1)(E)
>  The proposed regulations provide that activities related
to olefins derived from natural gas do not generate
qualified income
Williams view on proposed regulations …
>  Among other issues, the proposed regulations create a
distinction between petroleum and natural gas that
does not exist in the statute or legislative history
>  On July 2, 2012, Williams Partners received a Private
Letter Ruling (PLR) from the IRS that income from its
olefins assets is qualified
>  Williams believes its PLR is a correct interpretation of
the statute and legislative history
G - 23 Analyst Day 2015 | May 13, 2015
We are early in the process …
>  These proposed regulations are not final and are
subject to public comment
>  Williams is working with other industry participants to
develop comments for submission to IRS and Treasury
>  The process to finalize these regulations could take
anywhere from a matter of months to a matter of years
Potential implications for Williams and
Williams Partners …
>  The proposed regulations provide a 10 year transition
period, beginning when the regulations become final,
that would apply to current olefins operations
>  If, under final regulations, olefins income is no longer
considered qualified income, such income from current
operations would likely remain significantly less than
the 10% threshold due to growth in our qualified
income during the 10-year transition period. If nonqualified income was expected to approach or exceed
the 10% threshold, including new projects, we would
expect to use a “blocker” corporation and other tax
planning options to minimize the impact on its tax
obligations.

WMB Non-GAAP Reconciliations
WMB Non-GAAP Reconciliations
WMB Non-GAAP Disclaimer
> 
This presentation includes certain financial measures – adjusted EBITDA, adjusted income from continuing operations (“earnings”),
adjusted earnings per share, cash available for dividends, dividend coverage ratio, distributable cash flow and cash distribution
coverage ratio – that are non-GAAP financial measures as defined under the rules of the Securities and Exchange Commission
> 
Our segment performance measure, modified EBITDA is defined as net income (loss) before income tax expense, net interest expense,
equity earnings from equity-method investments, other net investing income, depreciation and amortization expense, and accretion
expense associated with asset retirement obligations for nonregulated operations. We also add our proportional ownership share (based
on ownership interest) of modified EBITDA of equity investments.
> 
Adjusted EBITDA further excludes items of income or loss that we characterize as unrepresentative of our ongoing operations and may
include assumed business interruption insurance related to the Geismar plant. Management believes this measure provides investors
meaningful insight into results from ongoing operations
> 
For Williams, cash available for dividends is defined as cash received from its ownership in MLPs, cash received (used) by its NGL &
Petchem Services segment (other than cash for capital expenditures) less interest, taxes and maintenance capital expenditures
associated with Williams and not the underlying MLPs. We also calculate the ratio of cash available for dividends to the total cash
dividends paid (dividend coverage ratio). This measure reflects Williams’ cash available for dividends relative to its actual cash dividends
paid.
> 
For Williams Partners L.P., we define distributable cash flow as adjusted EBITDA less maintenance capital expenditures, cash portion of
interest expense, income attributable to noncontrolling interests and cash income taxes plus WPZ restricted stock unit non-cash
compensation and certain other adjustments that management believes affects the comparability of results. Adjustments for
maintenance capital expenditures and cash potion of interest expense include out proportionate share of these items of our equitymethod investments.
> 
For Williams Partners L.P., we also calculate the ratio of distributable cash flow to the total cash distributed (cash distribution coverage
ratio). This measure reflects the amount of distributable cash flow relative to our cash distribution. We have also provided this ratio
calculated using the most directly comparable GAAP measure, net income.
> 
This presentation is accompanied by a reconciliation of these non-GAAP financial measures to their nearest GAAP financial measures.
Management uses these financial measures because they are accepted financial indicators used by investors to compare company
performance. In addition, management believes that these measures provide investors an enhanced perspective of the operating
performance of the Company’s assets and the cash that the business is generating.
> 
Neither adjusted EBITDA, adjusted income from continuing operations, cash available for dividends, nor distributable cash flow are
intended to represent cash flows for the period, nor are they presented as an alternative to net income or cash flow from operations.
They should not be considered in isolation or as substitutes for a measure of performance prepared in accordance with United States
generally accepted accounting principles.

WPZ Non-GAAP Reconciliations
WPZ Non-GAAP Reconciliations
WPZ Non-GAAP Disclaimer
> 
This presentation includes certain financial measures – adjusted EBITDA, distributable cash flow, and cash distribution coverage ratio –
that are non-GAAP financial measures as defined under the rules of the Securities and Exchange Commission
> 
Our segment performance measure, modified EBITDA, is defined as net income (loss) before income tax expense, net interest expense,
equity earnings from equity-method investments, other net investing income, depreciation and amortization expense, and accretion
expense associated with asset retirement obligations for nonregulated operations. We also add our proportional ownership share (based
on ownership interest) of modified EBITDA of equity investments.
> 
Adjusted EBITDA further excludes items of income or loss that we characterize as unrepresentative of our ongoing operations and may
include assumed business interruption insurance related to the Geismar plant. Management believes this measure provides investors
meaningful insight into results from ongoing operations.
> 
We define distributable cash flow as adjusted EBITDA less maintenance capital expenditures, cash portion of interest expense, income
attributable to noncontrolling interests and cash income taxes plus WPZ restricted stock unit non-cash compensation and certain other
adjustments that management believes affects the comparability of results. Adjustments for maintenance capital expenditures and cash
portion of interest expense include our proportionate share of these items of our equity-method investments.
> 
We also calculate the ratio of distributable cash flow to the total cash distributed (cash distribution coverage ratio). This measure reflects
the amount of distributable cash flow relative to our cash distribution. We have also provided this ratio calculated using the most directly
comparable GAAP measure, net income.
> 
This presentation is accompanied by a reconciliation of these non-GAAP financial measures to their nearest GAAP financial measures.
Management uses these financial measures because they are accepted financial indicators used by investors to compare company
performance. In addition, management believes that these measures provide investors an enhanced perspective of the operating
performance of the Partnership's assets and the cash that the business is generating.
> 
Neither adjusted EBITDA, nor distributable cash flow are intended to represent cash flows for the period, nor are they presented as an
alternative to net income or cash flow from operations. They should not be considered in isolation or as substitutes for a measure of
performance prepared in accordance with United States generally accepted accounting principles
