Hologic, Inc.  Notes to Consolidated Financial Statements—(Continued) (In thousands, except per share data) Future minimum lease payments under all the Company’s operating leases are approximately as follows:
## Table 0 ##
The Company subleases a portion of its Bedford facility and has received rental income of $277, $410 and $682 for fiscal years 2004, 2003 and 2002, respectively, which has been recorded as an offset to rent expense in the accompanying statements of income.
Rental expense, net of sublease income, was approximately $4,660, $4,963, and $2,462 for fiscal 2004, 2003 and 2002, respectively.9.  Business Segments and Geographic Information The Company reports segment information in accordance with SFAS No.131, Disclosures about Segments of an Enterprise and Related Information.
Operating segments are identified as components of an enterprise about which separate, discrete financial information is available for evaluation by the chief operating decision maker, or decision-making group, in making decisions how to allocate resources and assess performance.
The Company’s chief decision-maker, as defined under SFAS No.131, is the chief executive officer.
To date, the Company has viewed its operations and manages its business as four principal operating segments: the manufacture and sale of Mammography products, Osteoporosis Assessment products, Digital Detectors and Other products.
As a result of the Company’s implementation of a company wide integrated software application in fiscal 2003, identifiable assets for the four principal operating segments only consist of inventories, intangible assets, and property and equipment.
The Company has presented all other assets as corporate assets.
Prior periods have been restated to conform to this presentation.
Intersegment sales and transfers are not significant.
Noble Energy, Inc.  Notes to Consolidated Financial Statements 79 Allowance for Doubtful Accounts We routinely assess the recoverability of all material trade and other receivables to determine their collectibility.
We accrue a reserve on a receivable when, based on management’s judgment, it is probable that a receivable will not be collected and the amount of such reserve may be reasonably estimated.
Changes in the allowance for doubtful accounts were as follows:
## Table 1 ##
For a discussion of the SemCrude matter, see Note 17.
Commitments and Contingencies.
Through December 31, 2008, we had recorded an allowance for doubtful accounts of $57 million related to our Ecuador power operations.
The allowance was necessary to cover potentially uncollectible balances, as certain entities purchasing electricity in Ecuador have been slow to pay amounts due us.
As a result of pursuing various strategies to protect our interests, including international arbitration and litigation, we reached a settlement in fourth quarter 2008.
In March and April 2009, we received total payments of $60 million in accordance with the terms of the settlement, against which a reserve of $46 million had previously been recorded.
Accordingly, we reduced the allowance for doubtful accounts by $46 million and included the amount as a reduction in electricity generation expense in first quarter 2009.
We recorded an additional allowance of $14 million related to current period electricity sales in 2009.
Inventories Inventories consist primarily of tubular goods and production equipment used in our oil and gas operations and crude oil produced but not yet sold.
Materials and supplies inventories are stated at the lower of average cost or market.
The cost of crude oil inventory includes production costs and DD&A expense.
Inventories consisted of the following:
## Table 2 ##
Basic and Diluted Earnings Per Share Basic earnings per share (EPS) of our common stock have been computed on the basis of the weighted average number of shares outstanding during each period.
The diluted EPS of our common stock includes the effect of outstanding common stock equivalents.
See Note 14.
Earnings Per Share.
Related Party Transactions Following the Patina Merger in 2005, we entered into a consulting agreement with a former officer of Patina who now serves as a member of our Board of Directors.
Pursuant to the consulting agreement, we reimbursed his office space rent of $42,000 in 2007.
Contingencies We are subject to legal proceedings, claims and liabilities that arise in the ordinary course of business.
We accrue for losses associated with legal claims when such losses are considered probable and the amounts can be reasonably estimated.
See Note 17.
Commitments and Contingencies.
We self-insure the medical and dental coverage provided to certain employees, certain workers’ compensation and the first $1 million of general liability coverage.
Liabilities are accrued for self-insured claims, or when estimated losses exceed coverage limits, and when sufficient information is available to reasonably estimate the amount of the loss.
Concentration of Market Risk In 2009, Glencore Energy UK Ltd was the largest single non-affiliated purchaser of production and accounted for 25% of crude oil sales, or 16% of total oil, gas and NGL sales.
In 2008, Suncor Energy Marketing was the largest single non-affiliated purchaser of production and accounted for 22% of crude oil sales, or 13% of total oil, gas and NGL sales.
In 2007, Marathon Petroleum Supply Company was the largest single nonaffiliated purchaser of production and accounted for 18% of crude oil sales, or 10% of total oil, gas and NGL sales.
We believe the loss of any one purchaser would not have a material effect on our financial position or results of operations since there are numerous potential purchasers of our production.
Our share of operations of equity method investees was as follows:
