The tables below summarize gains and losses due to changes in fair value, including both realized and unrealized gains (losses), recorded in earnings for Level 3 assets and liabilities during 2009, 2008 and 2007.
These amounts include those gains (losses) generated by loans, LHFS, loan commitments and structured notes which are accounted for under the fair value option.

The El Dorado Refinery faces competition from other Plains States and Mid-Continent refiners, but the principal competitors for the El Dorado Refinery are Gulf Coast refiners.
Our Gulf Coast competitors typically have lower production costs due to greater economies of scale; however, they incur higher refined product transportation costs, which allows the El Dorado Refinery to compete effectively in the Plains States and Rocky Mountain region with Gulf Coast refineries.
The Tulsa Refineries serve the Mid-Continent region of the United States.
Distillates and gasolines are primarily delivered from the Tulsa Refineries to market via pipelines owned and operated by Magellan.
These pipelines connect the refinery to distribution channels throughout Colorado, Oklahoma, Kansas, Missouri, Illinois, Iowa, Minnesota, Nebraska and Arkansas.
Additionally, HEP's on-site truck and rail racks facilitate access to local refined product markets.
We have an offtake agreement through November 2019 with an affiliate of Sinclair whereby Sinclair purchases 45,000 to 50,000 BPD of gasoline and distillate products at market prices from us to supply its branded and unbranded marketing network throughout the Midwest.
Upon expiration, the offtake agreement can be renewed by Sinclair for an additional five-year term.
For the year ended December 31, 2017, sales to Sinclair represented approximately 21% of the Tulsa Refineries’total sales and 8% of our total consolidated sales.
The Tulsa Refineries’ principal customers for conventional gasoline include Sinclair, other refiners, convenience store chains, independent marketers and retailers.
Sinclair, truck stop operators and railroads are the primary diesel customers.
Jet fuel is sold primarily for commercial use.
The refinery's asphalt and roofing flux products are sold via truck or railcar directly from the refineries or to customers throughout the Mid-Continent region primarily to paving contractors and manufacturers of roofing products.
For the year ended December 31, 2017, sales to Shell Oil represented approximately 12% of our Mid-Continent refineries’ total sales and 9% of our total consolidated sales.
We have a sales agreement with an affiliate of Shell Oil under which Shell Oil purchases gasoline and diesel production of the El Dorado Refinery and Tulsa Refineries at market prices through October 2018 primarily to support its branded marketing network.
Products Set forth below is information regarding refined product sales attributable to our Mid-Continent region:
## Table 1 ##
Crude Oil and Feedstock Supplies Both of our Mid-Continent Refineries are connected via pipeline to Cushing, Oklahoma, a significant crude oil pipeline trading and storage hub.
The El Dorado Refinery and the Tulsa Refineries are located approximately 125 miles and 50 miles, respectively, from Cushing, Oklahoma.
Local pipelines provide direct access to regional Oklahoma crude production as well as access to United States onshore and Canadian crudes.
The proximity of the refineries to the Cushing pipeline and storage hub provides the flexibility to optimize their crude slate with a wide variety of crude oil supply options.
Additionally, we have transportation service agreements to transport Canadian crude oil on the Spearhead and Keystone Pipelines, enabling us to transport Canadian crude oil to Cushing for subsequent shipment to either of our Mid-Continent Refineries.
We also purchase isobutane, natural gasoline, butane and other feedstocks for processing at our Mid-Continent Refineries.
The El Dorado Refinery is connected to Conway, Kansas, a major gas liquids trading and storage hub, via the Oneok Pipeline.
From time to time, other feedstocks such gas oil, naphtha and light cycle oil are purchased from other refiners for use at our refineries.
Notes to Consolidated Financial Statements—(Continued) (Amounts in Millions, Except Per Share Amounts) Guarantees We have certain contingent obligations under guarantees of certain of our subsidiaries (“parent company guarantees”) relating principally to credit facilities, guarantees of certain media payables and operating leases.
The amount of such parent company guarantees was $255.7 and $327.1 as of December 31, 2008 and 2007, respectively.
In the event of non-payment by the applicable subsidiary of the obligations covered by a guarantee, we would be obligated to pay the amounts covered by that guarantee.
As of December 31, 2008, there are no material assets pledged as security for such parent company guarantees.
Contingent Acquisition Obligations We have structured certain acquisitions with additional contingent purchase price obligations in order to reduce the potential risk associated with negative future performance of the acquired entity.
In addition, we have entered into agreements that may require us to purchase additional equity interests in certain consolidated and unconsolidated subsidiaries.
The amounts relating to these transactions are based on estimates of the future financial performance of the acquired entity, the timing of the exercise of these rights, changes in foreign currency exchange rates and other factors.
We have not recorded a liability for these items since the definitive amounts payable are not determinable or distributable.
When the contingent acquisition obligations have been met and consideration is determinable and distributable, we record the fair value of this consideration as an additional cost of the acquired entity.
However, certain acquisitions contain deferred payments that are fixed and determinable on the acquisition date.
In such cases, we record a liability for the payment and record this consideration as an additional cost of the acquired entity on the acquisition date.
If deferred payments and purchases of additional interests after the effective date of purchase are contingent upon the future employment of the former owners then we recognize these payments as compensation expense.
Compensation expense is determined based on the terms and conditions of the respective acquisition agreements and employment terms of the former owners of the acquired businesses.
This future expense will not be allocated to the assets and liabilities acquired and is amortized over the required employment terms of the former owners.
The following table details the estimated liability with respect to our contingent acquisition obligations and the estimated amount that would be paid in the event of exercise at the earliest exercise date.
We have certain put options that are exercisable at the discretion of the minority owners as of December 31, 2008.
As such, these estimated acquisition payments of $5.5 have been included within the total payments expected to be made in 2009 in the table below and, if not made in 2009, will continue to carry forward into 2010 or beyond until they are exercised or expire.
All payments are contingent upon achieving projected operating performance targets and satisfying other conditions specified in the related agreements and are subject to revisions as the earn-out periods progress.
As of December 31, 2008, our estimated future contingent acquisition obligations payable in cash are as follows:
## Table 2 ##
We have entered into certain acquisitions that contain both put and call options with similar terms and conditions.
In such instances, we have included the related estimated contingent acquisition obligation in the period when the earliest related option is exercisable.
As a result of revisions made during 2008 to EITF Topic No.
