Operating Expenses The table below presents a comparison of our expenses on an absolute dollar basis and an equivalent unit of production (boe) basis.
Our discussion may reference expenses on a boe basis, on an absolute dollar basis or both, depending on context.
All operating expenses include costs attributable to a noncontrolling interest in Egypt.
Operating expenses for all periods exclude discontinued operations in Argentina and Australia.
## Table 2 ##
Recurring Depreciation, Depletion and Amortization (DD&A) 2015 vs.  2014 Oil and gas property recurring DD&A expense of $3.5 billion in 2015 decreased $857 million compared to 2014.
The Company’s oil and gas property recurring DD&A rate decreased $2.28 per boe in 2015 compared to 2014.
The primary factor driving both lower absolute dollar expense and lower DD&A per boe rates was the reduction in the Company’s oil and gas property carrying values resulting from significant property write-downs incurred during 2015.2014 vs.  2013 Recurring full-cost depletion expense decreased $146 million on an absolute dollar basis: $412 million on lower volumes partially offset by an increase of $266 million from a higher average cost rate per boe.
Our full-cost depletion rate increased $1.58 to $20.36 per boe reflecting increased cost for exploration and development activity over the prior years.
Additional DD&A Under the full-cost method of accounting, the Company is required to review the carrying value of its proved oil and gas properties each quarter on a country-by-country basis.
Under these rules, capitalized costs of oil and gas properties, net of accumulated DD&A and deferred income taxes, may not exceed the present value of estimated future net cash flows from proved oil and gas reserves, net of related tax effects and discounted 10 percent per annum and adjusted for cash flow hedges.
Estimated future net cash flows are calculated using endof-period costs and an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of the production, except where prices are defined by contractual arrangements.
At December 31, 2012, total future minimum commitments under existing non-cancelable operating leases and purchase obligations were as follows:
## Table 3 ##
(a) Includes $3.6 billion relating to fiber supply agreements entered into at the time of the Company’s 2006 Transformation Plan forestland sales and in conjunction with the 2008 acquisition of Weyerhaeuser Company’s Containerboard, Packaging and Recycling business.
Rent expense was $231 million, $205 million and $210 million for 2012, 2011 and 2010, respectively.
GUARANTEES In connection with sales of businesses, property, equipment, forestlands and other assets, International Paper commonly makes representations and warranties relating to such businesses or assets, and may agree to indemnify buyers with respect to tax and environmental liabilities, breaches of representations and warranties, and other matters.
Where liabilities for such matters are determined to be probable and subject to reasonable estimation, accrued liabilities are recorded at the time of sale as a cost of the transaction.
ENVIRONMENTAL PROCEEDINGS International Paper has been named as a potentially responsible party in environmental remediation actions under various federal and state laws, including the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).
Many of these proceedings involve the cleanup of hazardous substances at large commercial landfills that received waste from many different sources.
While joint and several liability is authorized under CERCLA and equivalent state laws, as a practical matter, liability for CERCLA cleanups is typically allocated among the many potential responsible parties.
Remedial costs are recorded in the consolidated financial statements when they become probable and reasonably estimable.
International Paper has estimated the probable liability associated with these matters to be approximately $92 million in the aggregate at December 31, 2012.
One of the matters referenced above is a closed wood treating facility located in Cass Lake, Minnesota.
During 2009, in connection with an environmental site remediation action under CERCLA, International Paper submitted to the EPA a site remediation feasibility study.
In June 2011, the EPA selected and published a proposed soil remedy at the site with an estimated cost of $46 million.
The overall remediation reserve for the site is currently $48 million to address this selection of an alternative for the soil remediation component of the overall site remedy.
In October 2011, the EPA released a public statement indicating that the final soil remedy decision would be delayed.
In the unlikely event that the EPA changes its proposed soil remedy and approves instead a more expensive clean-up alternative, the remediation costs could be material, and significantly higher than amounts currently recorded.
In October 2012, the Natural Resource Trustees for this site provided notice to International Paper and other potentially responsible parties of their intent to perform a Natural Resource Damage Assessment.
It is premature to predict the outcome of the assessment or to estimate a loss or range of loss, if any, which may be incurred.
In addition to the above matters, other remediation costs typically associated with the cleanup of hazardous substances at the Company’s current, closed or formerly-owned facilities, and recorded as liabilities in the balance sheet, totaled approximately $46 million at December 31, 2012.
Other than as described above, completion of required remedial actions is not expected to have a material effect on our consolidated financial statements.
The Company is a potentially responsible party with respect to the Allied Paper, Inc. /Portage Creek/ Kalamazoo River Superfund Site (Kalamazoo River Superfund Site) in Michigan.
The EPA asserts that the site is contaminated primarily by PCBs as a result of discharges from various paper mills located along the river, including a paper mill formerly owned by St.  Regis.
The Company is a successor in interest to St.  Regis.
International Paper has not received any orders from the EPA with respect to the site and is in the process of collecting information from the EPA and other parties relative to the Kalamazoo River Superfund Site to evaluate the extent of its liability, if any, with respect to the site.
Accordingly, it is premature to estimate a loss or range of loss with respect to this site.
Also in connection with the Kalamazoo River Superfund Site, the Company was named as a defendant by Georgia-Pacific Consumer Products LP, Fort James Corporation and Georgia Pacific LLC in a contribution and cost recovery action for alleged pollution at the Kalamazoo River Superfund Site.
The suit seeks contribution under CERCLA for $79 million in costs purportedly expended by plaintiffs as of the filing of the complaint, and for future remediation costs.
The suit alleges that a mill, during the time it was allegedly owned and operated by St.  Regis, discharged PCB contaminated solids and paper residuals resulting from paper de-inking and recycling.
Also named as defendants in the suit are NCR Corporation and Weyerhaeuser Company.
In mid-2011, the suit was
