Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	We prepare our financial statements in accordance with accounting principles generally accepted in the United States of America. Our preparation of these financial statements requires us to make estimates and assumptions that affect the reported amount of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. We regularly evaluate these estimates utilizing historical experience, consultation with experts and other methods we consider reasonable under the circumstances. Nevertheless, actual results may differ significantly from these estimates. We record the effect of any revisions to these estimates in our financial statements in the period in which the facts that give rise to the revision become known.
	Accounting for Investment in the Partnership
	We use the equity method of accounting for our ownership in the Partnership because we exercise significant influence over the Partnership pursuant to a delegation of control agreement among the General Partner, the Partnership and us. Our share of earnings of the Partnership is recorded in the period in which it is earned. As of December 31, 2013 and 2012, we owned approximately 19.2% and 13.3%, respectively, of the Partnership.
	Capital Account Adjustments on Issuances of Common Units by the Partnership
	The Partnership records an adjustment to the carrying value of its book capital accounts when it issues additional common units and the new issuance price per unit is greater than or less than the average cost per unit for each class of units. We refer to these adjustments as capital account adjustments. Beginning January 1, 2009, in conjunction with our adoption of the authoritative accounting guidance for noncontrolling interests, we recognize any capital account adjustments recorded by the Partnership to the book capital account it maintains for our i-units by increasing or decreasing our investment in the Partnership and recording a corresponding capital account adjustment directly to “Shareholders' equity” on our statements of financial position. We adopted prospectively the applicable authoritative guidance, except for any relevant presentation and disclosure requirements. Prior to our adoption of this guidance, we historically recognized the capital account adjustment recorded by the Partnership to the book capital account it maintains for our i-units by increasing or decreasing our investment in the Partnership and recording a corresponding gain or loss in our statements of income. Gain or loss recognition is an accounting convention we have historically applied as our method of recognizing these capital account adjustments made by the Partnership.
	Net Income Per Share
	Both basic and diluted earnings per share are computed based on the weighted-average number of our shares outstanding during each period. We have no securities outstanding that may be converted into or exercised for our shares.
	Income Taxes
	We are a limited liability company that has elected to be treated as a corporation for U. S. federal income tax purposes. We recognize deferred income tax assets and liabilities for temporary differences between the basis of our assets and liabilities for financial reporting and tax purposes. Changes in tax legislation are included in the relevant computations in the period in which the legislation is enacted. Currently, the only temporary difference (and associated deferred tax expense) results from recording our equity in the earnings of the Partnership which will not become taxable until the Partnership is liquidated, or the i-units are otherwise monetized.
	We are a party to a tax indemnification agreement with Enbridge. Pursuant to this tax indemnification agreement, Enbridge agrees to indemnify us from any tax liability attributable to our formation or our management of the business and affairs of the Partnership and from any taxes arising out of a transaction involving the i-units owned, to the extent the transaction does not generate cash sufficient to pay our taxes with respect to such transaction, in each case, other than any Texas franchise taxes and other capital-based foreign, state or local taxes that are required to be paid or reimbursed by the Partnership under the delegation of control agreement.
	The delegation of control agreement states that the General Partner bears the economic impact for our taxes only in the event we do not have cash sufficient to pay them. As a result, we accrue state income taxes in addition to federal income tax.
	Accounting for Uncertainty in Income Taxes
	Pursuant to the authoritative accounting guidance for accounting for uncertainty in income taxes, we recognize the tax effects of any uncertain tax positions as the largest amount that will more likely than not be realized upon ultimate settlement with a taxing authority having full knowledge of the position and all relevant facts. This guidance has not materially affected our operating results, cash flows or financial position.
	Comprehensive Income
	Comprehensive income differs from net income due to the equity in other comprehensive income or loss of the Partnership. The Partnership enters into a variety of derivative financial instruments to mitigate its exposure to commodity price and interest rate risk, most of which are qualified cash flow hedges under the applicable authoritative accounting guidance for derivative activities. As such, changes in the fair market value of the Partnership's derivative financial instruments produce fluctuations in our comprehensive income, which is reflected as equity in other comprehensive income or loss of the Partnership.
	Partnership Incentive Distribution Rights
	The General Partner of the Partnership receives incremental incentive cash distributions related to their incentive distribution rights, or IDR, on the portion of cash distributions that exceed certain target thresholds on a per unit basis under the Enbridge Energy Partners, L.P. partnership agreement. The incentive distributions payable to the Partnership's General Partner are 15%, 25% and 50% of all quarterly distributions of available cash that exceed target levels of $0.295, $0.35 and $0.495 per limited partner units, respectively. The distributable amount of the IDR is divided among the Partnership's limited partners: (1) Class A common units, (2) Class B common units and (3) i-units based on our ownership interest in the Partnership. Thus, our “Equity income (loss) from investment in Enbridge Energy Partners, L.P.” on our statements of income includes a pro-rata share of the IDR cost every quarter.

	4. SHARE DISTRIBUTIONS
	Our authorized capital structure consists of two classes of interests: (1) Listed Shares, which represent limited liability company interests with limited voting rights, and (2) voting shares, which represent limited liability company interests with full voting rights, all voting shares of which are held by the General Partner. Prior to the October 17, 2002 initial public offering of our Listed Shares, our issued capitalization consisted of cash contributed by the General Partner for one voting share.
	We make share distributions on a quarterly basis at the same time that the Partnership declares and makes cash distributions to the General Partner and the holders of its Class A and B common units. We do not, however, receive distributions of cash on the i-units we own and do not otherwise have any cash flow attributable to our ownership of the i-units. Instead, when the Partnership makes distributions of cash to the General Partner and holders of its Class A and B common units, we receive additional i-units under the terms of the Partnership's partnership agreement. The amount of the additional i-units we receive is calculated by dividing the amount of the per unit cash distribution paid by the Partnership on each of its Class A and B common units by the average closing price of one of our Listed Shares on the NYSE as determined for a 10 trading day period ending on the trading day immediately prior to the ex-dividend date for our shares multiplied by the number of shares outstanding on the record date. We concurrently distribute additional shares to our shareholders that are equivalent in number to the additional i-units we receive from the Partnership. As a result, the number of our outstanding shares is equal to the number of i-units that we own in the Partnership.
	The following table sets forth the details regarding our share distributions, as approved by our board of directors for the years ended December 31, 2013, 2012 and 2011.

	Partnership Preferred Unit Issuance
	On May 7, 2013, the Partnership sold to the General Partner 48,000,000 Preferred Units, representing limited partner interests in the Partnership for proceeds of approximately $1.2 billion. These Preferred Units are entitled to annual cash distributions, payable quarterly; however, during the first full eight quarters ending June 30, 2015, the cash distributions will accrue and accumulate and will be payable upon the earlier of the fifth anniversary of the issuance of Preferred Units or redemption of such Preferred Units by the Partnership. On or after June 1, 2016, at the sole option of the holder of the Preferred Units, the Preferred Units may be converted into the Partnership's Class A common units.
	At the time of issuance, the Preferred Units were issued at a discount to the market price of the Class A common units into which they are convertible. This discount represents a beneficial conversion feature, which is distributed ratably from the issuance date through the first available conversion date. The discount and cash distributions to the holder of the Preferred Units results in an increase in the Partnership's preferred capital and a decrease to our i-unit investment ownership in the Partnership through its impact to our “Equity income (loss) from investment in Enbridge Energy Partners, L.P.” on our statements of income. Quarterly cash distributions to the holder of the Preferred Units, whether accrued or paid, will reduce the amount of distributable available cash available to the Partnership's holders of general and limited partner units, including i-units.
	Partnership Issuances of Class A Common Units
	The Partnership records an adjustment to the carrying value of its book capital accounts when it issues additional common units and the new issuance price per unit is greater than or less than the average cost per unit for each class of units. We refer to these adjustments as capital account adjustments. Beginning January 1, 2009, in conjunction with our adoption of the authoritative accounting guidance for noncontrolling interests, we recognize any capital account adjustments recorded by the Partnership to the book capital account it maintains for our i-units by increasing or decreasing our investment in the Partnership and recording a corresponding capital account adjustment directly to “Shareholders' equity” on our statements of financial position. We adopted prospectively the applicable authoritative guidance, except for any relevant presentation and disclosure requirements. Prior to our adoption of this guidance, we historically recognized the capital account adjustment recorded by the Partnership to the book capital account it maintains for our i-units by increasing or decreasing our investment in the Partnership and recording a corresponding gain or loss in our statements of income. Gain or loss recognition is an accounting convention we have historically applied as our method of recognizing these capital account adjustments made by the Partnership.
	The following table presents the issuances of additional Class A common units by the Partnership for the years presented, excluding issuances under the Partnership's Equity Distribution Agreement, or EDA, and the Partnership's Amended and Restated Equity Distribution Agreement, or Amended EDA.

	Equity Distribution Agreement
	In June 2010, the Partnership entered into an Equity Distribution Agreement, which we refer to as the EDA, for the issue and sale from time to time of its Class A common units up to an aggregate amount of $150.0 million. On May 27, 2011, the Partnership entered into an Amended Equity Distribution Agreement, which we refer to as the Amended EDA, for the issue and sale from time to time of its Class A common units up to an aggregate amount of $500.0 million from the execution of the agreement through May 20, 2014. The units issued under the Amended EDA are in addition to the units offered and sold under the EDA.
	During the period from execution of the EDA through May 25, 2011, the Partnership sold 2,118,025 Class A common units, representing 4,236,050 units after giving effect to a two-for-one split of its Class A common units that became effective on April 21, 2011, for aggregate gross proceeds of $124.8 million of which $64.5 million are gross proceeds received in 2011, and no further sales were made under that agreement. On May 27, 2011, the Partnership de-registered the remaining aggregate $25.2 million of Class A common units that were registered under the EDA and remained unsold as of that date.
	The following table presents the net proceeds from the Partnership's Class A common unit issuances, resulting from the EDA or the Amended EDA, during the year ended December 31, 2011, and there were no such issuances in 2013 or 2012:

	Issuance of Listed Shares
	In March and September 2013, we completed public offerings of 10,350,000 and 8,424,686 Listed Shares, respectfully, representing limited liability company interests with limited voting rights, at a price to the underwriters of $26.44 and $28.02 per Listed Share, respectively. We received net proceeds of $272.9 million and $235.6 million for the March and September 2013 issuances, respectively, which we subsequently invested in an equal number of the Partnership's i-units.
	In November 2011, we completed a private offering of 860,684 Listed Shares to First Trust Energy Infrastructure Fund, representing limited liability company interests in us with limited voting rights, at a price of $29.86 per Listed Share. We received net proceeds of $25.5 million, which we also subsequently invested in an equal number of the Partnership's i-units.

	Partnership Preferred Unit Issuance
	On May 7, 2013, the Partnership sold to the General Partner 48,000,000 Preferred Units, representing limited partner interests in the Partnership for proceeds of approximately $1.2 billion. These Preferred Units are entitled to annual cash distributions, payable quarterly; however, during the first full eight quarters ending June 30, 2015, the cash distributions will accrue and accumulate and will be payable upon the earlier of the fifth anniversary of the issuance of Preferred Units or redemption of such Preferred Units by the Partnership. On or after June 1, 2016, at the sole option of the holder of the Preferred Units, the Preferred Units may be converted into the Partnership's Class A common units.
	At the time of issuance, the Preferred Units were issued at a discount to the market price of the Class A common units into which they are convertible. This discount represents a beneficial conversion feature, which is distributed ratably from the issuance date through the first available conversion date. The discount and cash distributions to the holder of the Preferred Units results in an increase in the Partnership's preferred capital and a decrease to our i-unit investment ownership in the Partnership through its impact to our “Equity income (loss) from investment in Enbridge Energy Partners, L.P.” on our statements of income. Quarterly cash distributions to the holder of the Preferred Units, whether accrued or paid, will reduce the amount of distributable available cash available to the Partnership's holders of general and limited partner units, including i-units.
	Partnership Issuances of Class A Common Units
	The Partnership records an adjustment to the carrying value of its book capital accounts when it issues additional common units and the new issuance price per unit is greater than or less than the average cost per unit for each class of units. We refer to these adjustments as capital account adjustments. Beginning January 1, 2009, in conjunction with our adoption of the authoritative accounting guidance for noncontrolling interests, we recognize any capital account adjustments recorded by the Partnership to the book capital account it maintains for our i-units by increasing or decreasing our investment in the Partnership and recording a corresponding capital account adjustment directly to “Shareholders' equity” on our statements of financial position. We adopted prospectively the applicable authoritative guidance, except for any relevant presentation and disclosure requirements. Prior to our adoption of this guidance, we historically recognized the capital account adjustment recorded by the Partnership to the book capital account it maintains for our i-units by increasing or decreasing our investment in the Partnership and recording a corresponding gain or loss in our statements of income. Gain or loss recognition is an accounting convention we have historically applied as our method of recognizing these capital account adjustments made by the Partnership.
The following table presents the issuances of additional Class A common units by the Partnership for the years presented, excluding issuances under the Partnership's Equity Distribution Agreement, or EDA, and the Partnership's Amended and Restated Equity Distribution Agreement, or Amended EDA.

Equity Distribution Agreement
In June 2010, the Partnership entered into an Equity Distribution Agreement, which we refer to as the EDA, for the issue and sale from time to time of its Class A common units up to an aggregate amount of $150.0 million. On May 27, 2011, the Partnership entered into an Amended Equity Distribution Agreement, which we refer to as the Amended EDA, for the issue and sale from time to time of its Class A common units up to an aggregate amount of $500.0 million from the execution of the agreement through May 20, 2014. The units issued under the Amended EDA are in addition to the units offered and sold under the EDA.
During the period from execution of the EDA through May 25, 2011, the Partnership sold 2,118,025 Class A common units, representing 4,236,050 units after giving effect to a two-for-one split of its Class A common units that became effective on April 21, 2011, for aggregate gross proceeds of $124.8 million of which $64.5 million are gross proceeds received in 2011, and no further sales were made under that agreement. On May 27, 2011, the Partnership de-registered the remaining aggregate $25.2 million of Class A common units that were registered under the EDA and remained unsold as of that date.
The following table presents the net proceeds from the Partnership's Class A common unit issuances, resulting from the EDA or the Amended EDA, during the year ended December 31, 2011, and there were no such issuances in 2013 or 2012:

	At the time of our initial public offering, we became a limited partner in the Partnership and, pursuant to a delegation of control agreement among us, the General Partner and the Partnership, assumed the management of the Partnership's business and affairs. Pursuant to this agreement, we have assumed substantially all of the General Partner's power and authority to manage the business and affairs of the Partnership and its subsidiaries. The delegation of control agreement provides that we will not amend or propose to amend the Partnership's partnership agreement, allow a merger or consolidation involving the Partnership, allow a sale or exchange of all or substantially all of the assets of the Partnership or dissolve or liquidate the Partnership without the approval of the General Partner.
	The General Partner remains responsible to the Partnership for actions taken or omitted by us while serving as the delegate of the General Partner as if the General Partner had itself taken or omitted to take such actions. The General Partner owns all of our voting shares. The General Partner has agreed not to voluntarily withdraw as general partner of the Partnership and has agreed not to transfer its interest as general partner of the Partnership unless the transferee agrees in writing to be bound by the terms and conditions of the delegation of control agreement that apply to the General Partner.
	The Partnership recognizes the delegation of rights and powers to us and indemnifies and protects us and our officers and directors to the same extent as it does with respect to the General Partner. In addition, the Partnership reimburses our expenses to the same extent as it does with respect to the General Partner as general partner. The Partnership also reimburses us for any Texas franchise taxes and any other similar capital-based foreign, state and local taxes not otherwise paid or reimbursed by Enbridge pursuant to the tax indemnification agreement.
	The General Partner, we and Enbridge, through its affiliates, provide the Partnership with managerial, administrative, operational and director services pursuant to service agreements among all of us. Pursuant to these service agreements, the Partnership reimburses us, the General Partner and affiliates of Enbridge for the costs of these managerial, administrative, operational and director services. Through an operational services agreement among Enbridge, affiliates of Enbridge and the Partnership, the Partnership is charged for the services of our executive management resident in Canada. Through a general and administrative services agreement among the Partnership, the General Partner, us and Enbridge Employee Services, Inc., a subsidiary of the General Partner, which we refer to as EES, the Partnership is charged for the services of our executive management resident in the United States. In addition, other employees of EES are assigned to work for the General Partner, the Partnership and us, and employer expenses for these employees are charged by EES to each of us, as appropriate. For the periods ended December 31, 2013, 2012 and 2011, all costs from EES incurred by us were charged to the Partnership pursuant to these agreements.

	7. INCOME TAXES
	Our long-term deferred income tax liability of $150.8 million and $143.8 million at December 31, 2013 and 2012, respectively, results from the deferred income tax expense associated with recording our equity in earnings of the Partnership and our share of the other comprehensive income of the Partnership. The terms of the i-units provide that the units owned by us will not be allocated income, gain, loss or deductions of the Partnership until such time that we dispose of our investment in the Partnership, thus resulting in the realization of the long-term deferred income tax liability. As of December 31, 2013 and 2012, we had no liability reported for unrecognized tax benefits.
	The effective income tax rates we used in computing the income tax provisions for the years ended December 31, 2013, 2012 and 2011 are presented in the following table:
			2013		2012		2011
		Federal statutory income tax rate	35	%	35	%	35	%
		State income tax rate	-4	%	2	%	2	%
		Effective income tax rate	31	%	37	%	37	%
	For the year ended December 31, 2013, the effective state income tax rate is negative due to an increase in the effective state income tax rate. The increase in the effective state income tax rate increased state income tax expense. This increased tax rate when applied to our temporary differences (differences between financial reporting and tax basis or our assets/liabilities) caused us to record state tax expense for the current period rather than the tax recovery that would be expected because of the pre-tax book loss we recorded for the current period. When tax expense is compared to our pre-tax book loss, this causes us to have a negative state income tax rate.
	Our tax years are generally open to examination by the Internal Revenue Service and state revenue authorities for the calendar years ended 2012, 2011 and 2010.

	9. EQUITY INCOME FROM THE PARTNERSHIP
	Our operating results, cash flows and financial position are dependent on the results of operations, cash flows and financial position of the Partnership. As a result, items that affect the operating results, cash flows and financial position of the Partnership will affect the amounts we report in our financial statements in proportion to our percentage ownership of the Partnership.
	For the year ended December 31, 2013, our net income decreased by $49.9 million resulting in a net loss of $18.1 million as compared to a net income in the same period in 2012. The net loss is primarily attributable to the $76.8 million decrease in equity income from investment in the Partnership compared to the same period in 2012.
	For the year ended December 31, 2012, the Partnership had higher operating and administrative expenses in each of its Liquids and Natural Gas segments. This increase in operating costs was primarily due to increased regulatory support costs, property taxes, integrity costs and additional workforce costs related to the expansion of its systems. As a result, our equity income was reduced by $12.4 million, after tax, which related to these increased operating costs.
	In June 2011, the Partnership recognized a settlement related to a dispute with a shipper for oil measurement adjustments the Partnership previously recognized in prior years, which positively impacted our equity income by $4.6 million after taxes. In addition, for the year ended December 31, 2011, our equity income included a $1.5 million after tax decrease of equity income we recorded for our share of cumulative aggregate costs recognized by the Partnership during the year ended December 31, 2011 for previously misstated NGL product purchases and sales that occurred at the Partnership's wholly-owned trucking and NGL marketing subsidiary over a period from at least 2005 through 2011. We recognized the additional equity loss following our determination that the previously unrecognized amounts were not material to the current or any prior period. As a result, for the year ended December 31, 2011, our equity income was understated by approximately $2.8 million after tax, which related to accounting misstatements for the Partnership's NGL product purchases and sales made for the year ended December 31, 2010 that were recorded in 2011.

The Partnership's distribution increased the number of i-units that we own. The number of i-units we received from the Partnership on February 14, 2014 was 1,241,652. The amount of this increase is calculated by dividing $0.54350, the cash amount distributed by the Partnership per common unit by $27.90, the average closing price of one of our Listed Shares on the NYSE for the 10 trading day period immediately preceding the ex-dividend date for our shares, multiplied by 63,743,099, the number of shares outstanding on the record date.

	(1)	In the first quarter of 2013, equity income from our investment in the Partnership was negatively affected by $18.0 million, after-taxes, due to additional environmental accruals recognized by the Partnership in response to the March 14, 2013 order from the Environmental Protection Agency for the Line 6B crude oil release.
	(2)	In the second quarter of 2013, we began receiving less allocating income from the Partnership due to the Preferred Units issuance which closed on May 8, 2013.
	(3)	In the third quarter of 2013, equity income from our investment in the Partnership was negatively affected by an increase in incentive income distributions to the General Partner.
	(4)	In the third quarter of 2012, equity income from our investment in the Partnership was positively affected by $12.5 million, after-taxes, due to insurance proceeds, net of accruals, received by the Partnership for the Line 6B crude oil release.
	(5)	In the fourth quarter of 2012, equity income from our investment in the Partnership was negatively affected because the Partnership received no additional insurance proceeds in connection with the Line 6B crude oil release, as compared to the $12.5 million, after taxes, in insurance proceeds that the partnership received in the third quarter of 2012.

	Both basic and diluted earnings per share are computed based on the weighted-average number of our shares outstanding during each period. We have no securities outstanding that may be converted into or exercised for our shares.
Income Taxes	'
	Income Taxes
	We are a limited liability company that has elected to be treated as a corporation for U. S. federal income tax purposes. We recognize deferred income tax assets and liabilities for temporary differences between the basis of our assets and liabilities for financial reporting and tax purposes. Changes in tax legislation are included in the relevant computations in the period in which the legislation is enacted. Currently, the only temporary difference (and associated deferred tax expense) results from recording our equity in the earnings of the Partnership which will not become taxable until the Partnership is liquidated, or the i-units are otherwise monetized.
	We are a party to a tax indemnification agreement with Enbridge. Pursuant to this tax indemnification agreement, Enbridge agrees to indemnify us from any tax liability attributable to our formation or our management of the business and affairs of the Partnership and from any taxes arising out of a transaction involving the i-units owned, to the extent the transaction does not generate cash sufficient to pay our taxes with respect to such transaction, in each case, other than any Texas franchise taxes and other capital-based foreign, state or local taxes that are required to be paid or reimbursed by the Partnership under the delegation of control agreement.
	The delegation of control agreement states that the General Partner bears the economic impact for our taxes only in the event we do not have cash sufficient to pay them. As a result, we accrue state income taxes in addition to federal income tax.
Accounting For Uncertainty In Income Taxes	'
	Accounting for Uncertainty in Income Taxes
	Pursuant to the authoritative accounting guidance for accounting for uncertainty in income taxes, we recognize the tax effects of any uncertain tax positions as the largest amount that will more likely than not be realized upon ultimate settlement with a taxing authority having full knowledge of the position and all relevant facts. This guidance has not materially affected our operating results, cash flows or financial position.
Comprehensive Income	'
	Comprehensive Income
	Comprehensive income differs from net income due to the equity in other comprehensive income or loss of the Partnership. The Partnership enters into a variety of derivative financial instruments to mitigate its exposure to commodity price and interest rate risk, most of which are qualified cash flow hedges under the applicable authoritative accounting guidance for derivative activities. As such, changes in the fair market value of the Partnership's derivative financial instruments produce fluctuations in our comprehensive income, which is reflected as equity in other comprehensive income or loss of the Partnership.
Incentive Distribution Policy, Managing Member or General Partner, Description [Policy Text Block]	'
	Partnership Incentive Distribution Rights
	The General Partner of the Partnership receives incremental incentive cash distributions related to their incentive distribution rights, or IDR, on the portion of cash distributions that exceed certain target thresholds on a per unit basis under the Enbridge Energy Partners, L.P. partnership agreement. The incentive distributions payable to the Partnership's General Partner are 15%, 25% and 50% of all quarterly distributions of available cash that exceed target levels of $0.295, $0.35 and $0.495 per limited partner units, respectively. The distributable amount of the IDR is divided among the Partnership's limited partners: (1) Class A common units, (2) Class B common units and (3) i-units based on our ownership interest in the Partnership. Thus, our “Equity income (loss) from investment in Enbridge Energy Partners, L.P.” on our statements of income includes a pro-rata share of the IDR cost every quarter.

	_____________________________
	(1)	In the first quarter of 2013, equity income from our investment in the Partnership was negatively affected by $18.0 million, after-taxes, due to additional environmental accruals recognized by the Partnership in response to the March 14, 2013 order from the Environmental Protection Agency for the Line 6B crude oil release.
	(2)	In the second quarter of 2013, we began receiving less allocating income from the Partnership due to the Preferred Units issuance which closed on May 8, 2013.
	(3)	In the third quarter of 2013, equity income from our investment in the Partnership was negatively affected by an increase in incentive income distributions to the General Partner.
	(4)	In the third quarter of 2012, equity income from our investment in the Partnership was positively affected by $12.5 million, after-taxes, due to insurance proceeds, net of accruals, received by the Partnership for the Line 6B crude oil release.
	(5)	In the fourth quarter of 2012, equity income from our investment in the Partnership was negatively affected because the Partnership received no additional insurance proceeds in connection with the Line 6B crude oil release, as compared to the $12.5 million, after taxes, in insurance proceeds that the partnership received in the third quarter of 2012.

In the third quarter of 2013, equity income from our investment in the Partnership was negatively affected by an increase in incentive income distributions to the General Partner.

[2]

In the second quarter of 2013, we began receiving less allocating income from the Partnership due to the Preferred Units issuance which closed on May 8, 2013.

[3]

In the first quarter of 2013, equity income from our investment in the Partnership was negatively affected by $18.0 million, after-taxes, due to additional environmental accruals recognized by the Partnership in response to the March 14, 2013 order from the Environmental Protection Agency for the Line 6B crude oil release.

[4]

In the fourth quarter of 2012, equity income from our investment in the Partnership was negatively affected because the Partnership received no additional insurance proceeds in connection with the Line 6B crude oil release, as compared to the $12.5 million, after taxes, in insurance proceeds that the partnership received in the third quarter of 2012.

[5]

In the third quarter of 2012, equity income from our investment in the Partnership was positively affected by $12.5 million, after-taxes, due to insurance proceeds, net of accruals, received by the Partnership for the Line 6B crude oil release.
