NICOR Exploration Company petitions this court to review a Federal Energy Regulatory Commission order granting Robert W. Scarth authority to collect incentive-based rates for natural gas pursuant to § 108 of the Natural Gas Policy Act (“NGPA”), 15 U.S.C. §§ 3301 et seq. The Commission concluded that the “area rate clauses” contained in gas supply contracts signed by NICOR and Scarth’s predecessors authorize Scarth to collect § 108 rates. The central issue raised by NICOR is whether the Commission’s interpretation of the contracts conflicts with Fifth Circuit precedent and Oklahoma contract law. We agree that the Commission failed to properly apply state contract law in construing the area rate clauses and that, under state law, Scarth failed to satisfy his burden of proof. Accordingly, we vacate the Commission’s order and remand the case to the Commission for entry of an order denying Scarth’s request for a rate increase.
I.
In 1970, NICOR signed three gas supply contracts with Scarth’s predecessors, GHK Co., Sun Oil Co., and the Amerada Hess Corporation (the “Producers”). Under the terms of the contracts, the Producers agreed to sell NICOR gas from the Green # 1-1 Well located in Beckham County, Oklahoma. Between 1988 and 1989, Scarth purchased the Producers’ interests in the three contracts and requested the Commission to reclassify the Green Well as a “stripper” well so that he could collect higher incentive-based rates under § 108 of the NGPA. NI-COR filed a petition with the Commission opposing Scarth’s rate increase.
The Supreme Court’s
Mobile-Sierra
Doctrine prohibits the Commission from granting a rate increase to a producer unless the producer’s contract authorizes a rate increase.
United Gas Pipe Line Co. v. Mobile Gas Serv. Corp.,
If the Federal Power Commission, or any successor governmental authority having jurisdiction in the premises, shall at any time hereafter prescribe, for the area in which the contract is located, a higher, applicable, just and reasonable area rate for the purchase of gas than the price herein provided to be paid, then the price to be paid by the Buyer to Seller for gas delivered under the provisions of this Agreement shall be increased to equal such higher price effective as of the date such higher price is made applicable to the gas sold hereunder. 1
These clauses thus authorized the Producers to increase the contract price to match the maximum rate for the area established by the Federal Power Commission (“FPC”), the Commission’s predecessor.
The scope of area rate clauses became a matter of extensive litigation with the passage of the NGPA in 1978. Prior to 1978, the FPC established “just and reasonable” area rates based on the producer’s cost of service. The NGPA eliminated the FPC’s power to set area rates and, in its place, established nation-wide statutory rate ceilings. Section 104 of the NGPA essentially adopted the FPC’s cost-based methodology for setting the rates of most natural gas committed or dedicated to interstate commerce prior to 1978. 15 U.S.C. § 3314. However, § 108 of the NGPA establishes *1345 special “incentive-based rates for low output “stripper” wells. 15 U.S.C. § 3318. These incentive-based rates are significantly higher than § 104’s cost-based rates. Attempts by producers to obtain § 108 rates raised the issue of whether pre-NGPA area rate clauses authorized producers to collect higher NGPA incentive-based rates.
The Commission addressed the scope of pre-NGPA area rate clauses in three agency orders, Orders 23, 23-A, and 23-B (“Order 23”),
2
and in
Independent Oil & Gas Ass’n of W. Virginia,
In Opinion 77, the Commission formulated specific guidelines for interpreting area rate clauses. Opinion 77 establishes a two-part inquiry for determining the parties’ intent. First, the Commission must consider extrinsic evidence probative of intent, including the parties’ negotiations, course of dealing, and other evidence of the circumstances surrounding the contract’s execution.
In such situations, we will generally conclude that a contract containing an area or national rate clause does not authorize collection of all NGPA rates if it contains the following disqualifying terms:
(1) it refers to rates established or prescribed by an administrative body;
(2) it couples the reference to administrative action with a reference to the Natural Gas Act or the “just and reasonable” standard of that Act; and
(3) it contains no additional language which has the effect of uncoupling the link between agency action and the statutory standard of the Natural Gas Act.
Id. at 61,398. According to the Commission, references to both administrative rate-setting and the NGA’s “just and reasonable” standard generally indicate that the parties intend to limit price increases to cost-based rates. Id. On the other hand, the Commission concluded that language severing the link between administrative action and a cost-based standard suggests that the parties intend to allow price increases to the maximum rate allowed by statute, whether cost-based or incentive-based. Id.
Applying Opinion 77’s methodology to NI-COR’s contracts, an administrative law judge (“ALJ”) concluded that the area rate clauses did not authorize Scarth to collect § 108 incentive-based rates.
The course of performance evidence, as well as the evidence on the other items *1346 involving reliable and probative extrinsic evidence of the parties’ intent, is clearly insufficient to support Scarth’s contention that the [area rate clauses] in issue entitle it to collect payment of section 108 NGPA ceiling prices.... In sum, such evidence not only does not suffice to overcome Scarth’s admitted burden of demonstrating ... the contracting parties’ intent to pay and collect incentive-based NGPA section 108 rates, but rather supports the conclusion that the [clauses] in question contemplated payment and collection of only cost-based prices.
The ALJ also applied Opinion 77’s three-prong formula and found that the language of the area rate clauses satisfied the formula’s three elements.
The Commission initially affirmed the ALJ’s order.
According to the Commission, the area rate clause in the Amerada Hess contract failed to refer to the NGA or to the “just and reasonable” standard as required by the second prong of the formula. The Commission further concluded that the area rate clauses in the GHK and Sun contracts similarly allowed § 108 rates because the presence of the phrase “any successor or governmental authority” uncoupled the link between the contracts’ references to administrative action and the “just and reasonable” standard. 3 According to the Commission, this language is consistent with Congressionally-estab-lished rates under the NGPA.
NICOR requested judicial review of the Commission’s final order pursuant to 15 U.S.C. §§ 717r(b) and 3416(a)(4). We granted Robert W. Scarth’s motion to intervene in support of Commission’s order.
II.
NICOR maintains that the Commission’s application of Opinion 77’s methodology in the present case conflicts with Fifth Circuit precedent and Oklahoma contract law. NI-COR contends that the Commission failed to follow state law in construing the area rate clauses as required by this court’s decision in
Pennzoil Co. v. FERC,
A.
As a preliminary matter, Scarth questions whether NICOR properly preserved the arguments raised in its petition. Scarth contends that NICOR waived these arguments when it failed to file any objections to the ALJ’s initial order. Although the ALJ ruled in favor of NICOR, Scarth points out that the ALJ relied on the same methodology that NICOR now assails.
Scarth bases his waiver argument on 15 U.S.C. § 717r(b). Section 717r(b) grants courts of appeal original jurisdiction to review final orders issued by the Commission. However, this section further provides that “[n]o objection to the order of the Commission shall be considered by the court unless such objection shall have been urged before the Commission in the application for rehearing.” This waiver provision is construed as a
*1347
strict jurisdictional limitation on this court’s power to review the Commission’s orders.
Tennessee Gas Pipeline Co. v. FERC,
Our review of the record persuades us that Scarth’s waiver argument is without merit. Although NICOR failed to raise any objections to the ALJ’s application of Opinion 77 or to the Commission’s initial order affirming the ALJ’s decision, NICOR raised its objections in a motion for rehearing following the Commission’s final order reversing the ALJ and ruling against NICOR. Until that point in the proceeding, NICOR was the prevailing party. We reject Scarth’s claim that § 717r(b) requires a prevailing party to file objections to a favorable ruling by an ALJ in order to preserve its right to appeal if the ALJ’s decision is later reversed by the Commission. As long as a party in Nieor’s position presents its objections to the Commission in a timely motion for rehearing, § 717r(b)’s requirements are satisfied. We therefore conclude that NICOR properly preserved the issues raised in its petition by timely raising its objections in its motion for rehearing following the Commission’s final order. We now turn to the merits of NI-COR’s argument that the Commission failed to follow Oklahoma law in interpreting the area rate clauses.
B.
In
Pennzoil I,
we held that the Commission must apply state contract law in construing gas supply contracts.
NICOR contends that the Commission’s application of Opinion 77’s interpretive standards runs afoul of Pennzoil I because it is inconsistent with Oklahoma contract law. NICOR focusses on two aspects of the Commission’s methodology that it argues are inconsistent with Oklahoma contract law. First, NICOR faults the Commission for basing its interpretation solely on language in the area rate clauses that the Commission admits is ambiguous without also considering the extrinsic evidence of the parties’ intent. Second, NICOR contends that the Commission’s methodology essentially relieved Scarth of his burden of proving that the area rate clauses permit § 108 rates.
We must first address NICOR’s contention that Oklahoma contract law governs the interpretation of the area rate clauses at issue. In
Pennzoil I,
we held that the choice of which state’s law to apply “is properly a matter within federal common law.”
Although we are not bound by Oklahoma choice of law rules, these rules may guide us in deciding whether Oklahoma law should apply in the present case. Oklahoma choice of law rules for contracts require courts to apply “the law of the state (1) chosen by the parties, (2) where the contract was entered into, or (3) the place of performance if indicated in the contract.”
Moore v. Subaru of America,
Turning to the Commission’s application of Oklahoma law, we generally do not defer to the Commission’s interpretation of gas supply contracts unless the Commission relied on its factual or technical expertise in reaching its conclusions.
Tennessee Gas Pipeline Co. v. FERC,
We agree with NICOR that the Commission’s application of Opinion 77 to the present case conflicts with Oklahoma contract law. Oklahoma law directs courts to consider extrinsic evidence of the parties’ mutual intent in cases where the language of a contract is ambiguous.
See Mercury Investment Co. v. F.W. Woolworth Co.,
The Commission failed, however, to give any weight to the extrinsic evidence of the parties’ intent in concluding that NICOR’s area rate clauses authorized § 108 rates. While the Commission initially considered extrinsic evidence concerning the parties’ negotiations and course of dealing, the Commission concluded that this evidence was inconclusive. The Commission then construed the area rate clauses solely on the basis of the language of the clauses and Opinion 77’s three-part formula:
Sinee the Commission found that none of the parties produced such evidence of mutual intent, the Commission affirmed the ALJ to that extent and, like the ALJ, resolved the matter solely by application of the interpretive standards.
In construing the language of area rate clauses, however, the Commission must consider
“all
evidence — contract language, oral and written extrinsic evidence and evidence of course of performance.”
Hunt Oil Co. v. FERC,
The Commission’s approach is also inconsistent with state law to the extent that it narrowly focuses on specific phrases in the area rate clauses without considering the language of the clauses and contracts as a whole. OMahoma law requires courts to consider a contract as a whole “without narrowly concentrating upon some phrase or language taken out of context.”
Bonner v. Oklahoma Rock Corp.,
Finally, we agree that the Commission erred by relieving Scarth of his burden of proving by a preponderance of the evidence that the area rate clauses authorized § 108 rates. In applying Opinion 77, the Commission essentially shifted the burden of proof by requiring NICOR to prove the absence of contractual authority for § 108 rates. The ALJ concluded that Scarth failed to satisfy his burden of proof with regard to the extrinsic evidence of intent. Although the Commission accepted this finding, it applied Opinion 77’s three-part formula because NICOR failed to prove that the parties mutually intended to limit rate increases to cost-based rates:
Scarth failed to prove a mutual intent to authorize the payment of incentive rates. However, this also means that NICOR did not prove by a preponderance of the evidence that the parties had the mutual intent to limit area rate clause price escalations to only cost-based rates. Under the procedures established in Opinion 77, to win the case at the evidentiary stage and not reach the interpretive standards, NICOR had to prove by extrinsic evidence that its alleged intent was shared by each of the producer/sellers.
The Commission’s allocation of the burden of proof conflicts with this court’s holding in
Pennzoil I
that the producer bears the burden of proving that an area rate clause authorizes incentive-based rates under the NGPA.
We conclude, therefore, that the Commission failed to follow state contract law in construing NICOR’s area rate clauses. Based on the findings in the ALJ’s order and the Commission’s original order affirming the ALJ, Scarth failed to prove by a preponderance of the evidence that the contracting parties intended to authorize § 108 prices. Scarth thus failed to meet his burden of proof under Oklahoma contract law and
Pennzoil I.
We therefore VACATE the Commission’s order and REMAND the case to the Commission for entry of an order denying Scarth’s request for a rate increase.
See Hunt Oil,
VACATED and REMANDED.
Notes
. The only substantive difference is that the area rate clause in the Amerada Hess contract omits the phrase "just and reasonable.”
. Order 23, 6 FERC (CCH) ¶ 61,229 (March 13, 1979); Order 23-A, 7 FERC (CCH) ¶ 61,247 (June 12, 1979); Order 23-B, 8 FERC (CCH) ¶ 61,130 (Aug. 6, 1979). The Commission promulgated Rule 23 after extensive feedback and comment from gas producers, pipelines, and local distributors. The Fifth Circuit upheld the order in
Pennzoil Co. v. FERC,
. The Commission expressly addressed the impact of this type of language in Opinion 77:
Such an uncoupling could occur, for example, where a reference to the Natural Gas Act or the "just and reasonable" standard is supplemented by the phrase "or successor statutory authority” or words of similar import. In this circumstance, the parties commit their contractual destiny to a change in the statutory scheme and give advance acceptance to the outcome of the legislative process.
. Hunt does not indicate whether the Commission applied Opinion 77's three-prong formula.
