Before PHILLIPS, McHUGH, and MORITZ, Circuit Judges.
                   _________________________________


      This appeal challenges the district court’s approval of a class settlement

agreement over the objections of four class members. We discern no abuse of

discretion and thus affirm the district court’s decision.

                                I.     BACKGROUND

      Appellee-Defendant TEP Rocky Mountain LLC (“TEP”) operates wells that

produce natural gas in Colorado. These wells are subject to various leases or royalty

agreements (“royalty instruments”) under which the owners of such instruments

receive a share of profits from the sale of natural gas.

      In 2006, a class of plaintiffs filed suit (the “Lindauer litigation”) in Colorado

state court, alleging that TEP had underpaid royalties on various royalty instruments.

In 2008, TEP and the Lindauer class entered into a settlement agreement (the

“Lindauer SA”) purporting to “resolve all class claims relating to past calculation of

royalt[ies]” and to “establish certain rules to govern future royalty” payments. App.

at 411. The Lindauer SA categorized members of the class into thirteen separate

categories based on the specific terms of their royalty instruments, and set forth

different royalty calculation methods for each category.


      *
         This order and judgment is not binding precedent, except under the doctrines
of law of the case, res judicata, and collateral estoppel. It may be cited, however, for
its persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.
                                            2
      Approximately eight years passed, seemingly free of incident. But on July 18,

2017, Elna Sefcovic, LLC, White River Royalties, LLC, Juhan, LP, and Roy Royalty,

Inc., individually and on behalf of a subset of royalty owners who were party to the

Lindauer SA (the “Sefcovic class”), initiated this action against TEP in Colorado

state court, alleging that TEP had calculated and paid royalties in a manner

inconsistent with the Lindauer SA and contrary to the underlying royalty agreements.

TEP removed the case to federal court on August 17, 2017, and subsequently asserted

a counterclaim against the Sefcovic class for an offset of ad valorem taxes owing to

any repayment of royalties by TEP. The parties engaged in discovery and ultimately

reached a proposed class settlement (the “Sefcovic SA”).

      The Sefcovic SA creates four subclasses composed of four of the thirteen

categories created by the Lindauer SA. These subclasses sort class members

according to the rights their royalty instruments grant TEP with respect to deductions

from royalty payments. The Lindauer categories that comprise the Sefcovic

subclasses are categories two, three, five, and eleven. Category two agreements allow

“deduction of transporting gas ‘from the mouth of the well to the point of sale,’ or

‘customary transportation costs,’ or ‘all transportation charges.’” App. at 983.

Category three agreements allow “deduction of third party transportation costs from

the mouth of the well to the point of sale.” Id. Category five agreements

“[c]alculate[] royalty payments based on, for example, ‘market value at the well,’

‘proceeds at the well,’ ‘market value,’ or ‘proceeds.’” Id. And category eleven

agreements “[c]alculate[] royalty payments based on ‘gross proceeds.’” Id.

                                           3
      The Sefcovic subclasses, in turn, are composed as follows. Subclass 1

comprises owners of category two and category three agreements. Subclass 2

comprises owners of category five agreements. Subclass 3 comprises owners of

category eleven agreements. And Subclass 4 comprises owners with agreements that

were categorized as either five or eleven at the time of the Lindauer SA, but were not

“currently . . . identified by TEP as exclusively [category five] or [category eleven]”

agreements. The following table illustrates the relationship between the Sefcovic

subclasses and the Lindauer categories.



                        Lindauer Category two: instruments allowing “deduction of
                        transporting gas ‘from the mouth of the well to the point of
                        sale,’ or ‘customary transportation costs,’ or ‘all transportation
 Sefcovic Subclass 1    costs.’” App. at 983.

                        Lindauer Category three: instruments allowing deductions “of
                        third party transportation costs from the mouth of the well to
                        the point of sale.” App. at 983.
                        Lindauer Category five: instruments that “[c]alculate[] royalty
                        payments based on, for example, ‘market value at the well,’
Sefcovic Subclass 2     ‘proceeds at the well,’ ‘market value,’ or ‘proceeds.’”
                        App. at 983.

                        Lindauer Category eleven: instruments that “[c]alculate[]
Sefcovic Subclass 3     royalty payments based on ‘gross proceeds.’” App. at 983.

                        Instruments that were categorized as either Lindauer category
                        five or eleven at the time of the Lindauer SA, but were not
Sefcovic Subclass 4     “currently . . . identified by TEP as exclusively [category five]
                        or [category eleven]” agreements. App. at 292.




                                            4
      The Sefcovic SA allocates settlement payments by subclass: Subclass 1

receives $454,845; Subclass 2 receives $5,787,732; Subclass 3 receives $1,157,145;

and Subclass 4 receives $2,625,587. The settlement payment for Subclass 1 is “the

equivalent of (a) 50% of all processing costs deducted from their payments since July

2016, and (b) over 40% of all fuel costs deducted from their payments since July

2011.” App. at 1190.

      On August 16, 2018, the district court1 issued an order preliminarily approving

the settlement and permitting notice to be mailed to the Sefcovic class members. On

November 6, 2018, appellants Charles Gonzales, Susannah Gonzales, Ted Vaughn,

and Hilda Vaughn (collectively, the “Objectors”) filed various objections to approval

of the proposed Sefcovic SA, including that the proposed settlement sacrificed the

interests of certain class members, that the notice to class members was insufficient,

and that the settlement’s release of claims was overly broad.

      The Objectors each own royalty instruments falling in category two of the

Lindauer SA and are therefore members of Subclass 1, as defined by the Sefcovic SA.

The Lindauer SA treated category two royalty instruments differently than other

categories. Although the Lindauer SA provided compensation to category two and

category three owners for disputed past deductions, it did not clarify which

deductions would be permitted prospectively under category two and category three


      1
        The Sefcovic class and TEP consented to the Magistrate Judge presiding over
this matter. We therefore refer to the Magistrate Judge’s orders as those of the district
court.

                                           5
leases. Instead, the Lindauer SA left the issue unresolved, declaring that “nothing

herein prohibits [TEP]2 from taking any Deductions it claims it is entitled to take

under the terms of [category two and category three (i.e., Subclass 1)] Royalty

Instruments, and nothing herein prohibits any Settlement Class Member from

challenging such deductions.” App. at 424. The Sefcovic SA resolves this dispute in

TEP’s favor, declaring that TEP is entitled to deduct from Subclass 1 members “a

proportionate share of those members’ gathering and fuel costs.” App. at 1473.

      On February 20, 2019, the court held a final fairness hearing on the proposed

Sefcovic settlement.3 The court heard extensive testimony from class members,

potential class members who opted out of the settlement, accounting experts, and

Objectors’ counsel. Relevant here, the court also heard testimony from Susan Jerman,

the owner of Subclass 1 representative White River Royalties, LLC. Ms. Jerman, who

has worked in the oil and gas industry for forty years, testified that the deduction

allowance provision in her category two agreement was weak as compared to the

instruments in other subclasses, and thus, she believed the Sefcovic SA was “a fair



      2
        The Lindauer SA refers to “Williams,” TEP’s predecessor. In 2015, TEP
acquired a controlling interest in Williams, which had at times operated under the
name WPX. Following the parties’ lead, we refer to WPX when discussing events
that occurred before TEP’s acquisition of that entity.
      3
          In the months between preliminary approval of the settlement agreement and
the final fairness hearing, the class representatives of the Lindauer class intervened in
this litigation to seek dismissal of the action for lack of subject matter jurisdiction.
The district court ultimately rejected that attempt, which decision forms the basis of a
separate appeal (Case No. 19-1121) heard by the same panel and resolved by a
separate Opinion issued concurrently with this Order and Judgment.
                                           6
settlement.” App. at 1597. Having “read and considered all submissions in

connection” with the Sefcovic SA, the district court approved the settlement and

incorporated its terms into the court’s final order. App. at 1461.

       This timely appeal followed.

                                      II.    DISCUSSION

       Objectors assert on appeal that (1) the settlement is not fair; (2) Subclass 1

representatives did not adequately represent the rights of absent Subclass 1 members;

(3) notice of the class settlement was inadequate; and (4) the settlement agreement’s

release of claims is too broad.4 We analyze each matter in turn and conclude that

(1) the district court did not exceed its discretion in deeming the settlement fair;


       4
         Objectors also seek reversal on grounds that the district court failed to
conduct a “rigorous analysis” of their objections before approving the Sefcovic SA.
But as Objectors conceded at oral argument, the “rigorous analysis” requirement
refers to a district court’s obligation when asked to certify a class under Rule 23(a).
See Wal-Mart Stores, Inc. v. Dukes, 564 U.S. 338, 350–51 (2011) (explaining that
“certification is proper only if ‘the trial court is satisfied, after a rigorous analysis,
that the prerequisites of Rule 23(a) have been satisfied’” (quoting Gen. Tel. Co. of
Sw. v. Falcon, 457 U.S. 147, 161 (1982)). Setting aside their inapposite reference to
the “rigorous analysis” requirement, we understand Objectors to argue that the
district court (1) failed to ask sufficiently probing questions of witnesses at the
fairness hearing, and (2) failed to adequately address their objections in its order
approving the settlement. But our review of the lengthy fairness hearing transcript
reveals the district court was fully engaged and understood its role in protecting the
interests of absent class members. And we see no deficiency in the district court’s
order approving the settlement. See Weinman v. Fid. Capital Appreciation Fund (In
re Integra Realty Res., Inc.), 354 F.3d 1246, 1268 (10th Cir. 2004) (rejecting a
similar challenge to an order approving a settlement by explaining that the district
court need do no more than provide “some basis for distinguishing [on appellate
review] between well-reasoned conclusions arrived at after a comprehensive
consideration of all relevant factors, and mere boilerplate approval phrased in
appropriate language but unsupported by evaluation of the facts or analysis of the
law” (quoting Newman v. Stein, 464 F.2d 689, 692 (2d Cir. 1972))).
                                             7
(2) Objectors did not preserve their challenge to the adequacy of Subclass 1

representatives; (3) notice of the proposed settlement was adequate; and (4) the

released claims share a factual predicate with the claims asserted in the complaint.

                         A. The Fairness of the Settlement Agreement

         The district court may approve a proposed settlement “only after a hearing and

only on finding that it is fair, reasonable, and adequate.” Fed. R. Civ. P. 23(e)(2). We

review the district court’s decision to approve a class settlement for an abuse of

discretion. Tennille v. W. Union Co., 785 F.3d 422, 434 (10th Cir. 2015). Thus, “we

will not disturb the determination absent a distinct showing it was based on a clearly

erroneous finding of fact or an erroneous conclusion of law or manifests a clear error

of judgment.” Rutter & Wilbanks Corp. v. Shell Oil Co., 314 F.3d 1180, 1187 (10th

Cir. 2002) (quotation marks omitted).

         Like the district court, our review focuses on whether “(1) the settlement was

fairly and honestly negotiated, (2) serious legal and factual questions placed the

litigation’s outcome in doubt, (3) the immediate recovery was more valuable than the

mere possibility of a more favorable outcome after further litigation, and (4) [the

parties] believed the settlement was fair and reasonable.” Tennille, 785 F.3d at 434

(alteration in original) (quotation marks omitted); see Weinman v. Fid. Capital

Appreciation Fund (In re Integra Realty Res., Inc.), 354 F.3d 1246, 1266 (10th Cir.

2004).

         Objectors do not structure their arguments to correspond to the controlling

Tennille factors; instead they advance general attacks on the fairness of the

                                             8
settlement agreement. Thus, we review the district court’s analysis within the context

of the Tennille factors, addressing Objectors’ arguments alongside the factor to which

they best correspond.

   1. The Settlement was Fairly and Honestly Negotiated

       As to the first factor, the district court found, and Objectors do not directly

dispute, that the settlement agreement was “the product of good faith arm’s length

negotiations between the Parties who are represented by very experienced and

capable counsel.” App. at 1461. Some of Objectors’ other fairness arguments, as well

as their attack on the breadth of the settlement’s release, might rest on an implication

that the settlement was not fairly negotiated. But Objectors make no specific

assertion on appeal that the settlement was not reached through a fair and honest

negotiation process. We therefore see no error in the district court’s conclusion that it

was.

   2. Serious Legal and Factual Questions Placed the Litigation’s Outcome in
      Doubt

       With respect to the second Tennille factor, we easily conclude that serious

legal and factual questions placed in doubt the outcome of litigation about the

deductions TEP could take from royalty payments made to Subclass 1. The crux of

the dispute between Objectors and Appellees over the value of Subclass 1 royalties

relates to the interpretation of the language permitting TEP to deduct the costs of

“transporting gas ‘from the mouth of the well to the point of sale.’” App. at 983.

Objectors contend that the presence of “transporting” or “transportation” in these


                                            9
instruments narrows the much broader clause that follows—“from the mouth of the

well to the point of sale”—thereby excluding the deduction of any costs for gathering

or fuel. Appellees, by contrast, assert that both gathering and fuel costs are

encompassed in the process of transporting gas “from the mouth of the well to the

point of sale.” App. at 983. The evidence adduced at the fairness hearing adequately

established a substantial risk that, if litigated, Objectors’ gathering limitation

argument would be rejected on its merits. For example, Subclass 1 representative

Ms. Jerman confirmed that she was not “aware of any means by which gas would get

from . . . the mouth of the well to a processing plant other than through a gathering

system.” App. at 1582.

       Thus, setting aside the time, expense, and delayed recovery attendant to more

litigation, Subclass 1 members faced a legitimate risk of recovering none of the fuel

repayments they enjoy under the Sefcovic SA. And even if they secured those

repayments, the victory could have been meaningless if it was combined with an

adverse ruling on TEP’s counterclaim seeking an offset of ad valorem tax liability

allegedly triggered by such repayments. By agreement of the parties, TEP’s

counterclaim was dismissed by the district court’s order approving the Sefcovic SA.

   3. The Immediate Recovery was More Valuable Than the Mere Possibility of
      a More Favorable Outcome After Further Litigation

       Relevant to this Tennille factor, Objectors claim there can be no worse position

for Subclass 1 members than the one they occupy by virtue of the Sefcovic SA. This

is so, Objectors insist, for two reasons. First, Objectors claim the agreement resolves


                                            10
the purportedly uncertain meaning of “from the mouth of the well to the point of

sale” against them. Second, they contend the Sefcovic SA permits TEP to recoup

charges that were not incurred during the relevant period and that completely offset

the settlement money allocated to Subclass 1.

      Objectors’ first argument appears based, primarily, on the fact that the

Lindauer SA had secured for category two and category three owners (Subclass 1

members in this litigation) repayment of some deductions TEP will be permitted to

deduct prospectively under the Sefcovic SA. They suggest that because a dispute

about the meaning of those royalty instruments yielded remuneration in the Lindauer

SA, the contractual language must have more settlement value than the Sefcovic SA

achieves for Subclass 1 members. But Objectors overstate the effect of the Lindauer

SA. There, the parties were unable to resolve the meaning of the deduction provisions

in category two and category three royalty instruments and left the issue unresolved.

The Lindauer SA did include a lump sum payment to category 2 and category 3

owners, which counsel for Objectors claims was intended as recoupment of the

disputed deductions. But TEP disagrees about the purpose of the lump sum payment

and argues that after the Lindauer SA, WPX continued to deduct the disputed costs.

      To be sure, WPX paid a lump sum to end the Lindauer litigation. But in doing

so, it never conceded that such deductions were impermissible. WPX then transferred

whatever rights it had in the royalty instruments to TEP, and TEP interpreted the

provisions in the Subclass 1 royalty instruments as allowing for the deductions for

fuel and gathering costs from the mouth of the well to the point of sale. Given the

                                          11
language of the royalty instruments held by Subclass 1 members, TEP had a strong

argument it was permitted to do so, and the Lindauer settlement payment does not

diminish the strength of that argument.

      It is also true that under the Sefcovic SA, Objectors received immediate

compensation in exchange for their release of claims. This compensation took the

form of repayment of “the equivalent of (a) 50% of all processing costs deducted

from their payments since July 2016, and (b) over 40% of all fuel costs deducted

from their payments since July 2011.” App. at 1190. Had the case proceeded to trial,

there is no guarantee Subclass 1 members would have been entitled to any repayment

of processing or fuel costs. Because the outcome of this litigation was, at best,

uncertain, and because Subclass 1 members obtained immediate recovery of a portion

of past deductions, the district court did not abuse its discretion in determining that

“the immediate recovery was more valuable than the mere possibility of a more

favorable outcome after further litigation.” Tennille, 785 F.3d at 434.

      As to Objectors’ second argument—that the Sefcovic SA’s recoupment

provision completely offsets the settlement money—the record before the district

court is sparse, presumably because this argument was not the focus of the

proceedings below. The expert testimony offered to quantify the potential

recoupment liability of Subclass 1 members is terse and undeveloped. But as we now

explain, TEP’s accounting expert, Alan Simpson, provided an explanation for his

conclusion that can be understood and verified. In turn, Objector’s expert, Mary

Ellen Denomy, provided an opinion untethered to any rational analysis. Under these

                                           12
circumstances, we cannot conclude the district court abused its discretion in rejecting

Objectors’ argument that ¶ 9.b rendered the Sefcovic SA fundamentally unfair.

       Under ¶ 9.b of the Sefcovic SA, TEP is permitted “to recoup any overpayments

made to Class members prior to the Effective Date as a result of not deducting

allowable post-production costs.” App. at 314. Objectors did not assert any complaint

about ¶ 9.b in their initial objections or in their brief submitted in advance of the

fairness hearing. Instead, they focused their written materials on the unfairness of the

method for prospectively calculating royalties for Subclass 1 members under ¶ 9.a.

       To the extent either party elicited testimony about the impact of ¶ 9.b at the

fairness hearing, it was limited. On direct examination, TEP’s counsel asked his

accounting expert, Alan Simpson, about the gathering and fuel deductions for

Subclass 1 owners. Mr. Simpson explained that “[d]uring the WPX era, there were

deductions to the subclass 1 owners for both gathering transportation and for fuel.”

App. at 1621. The district court interjected at that point, asking Mr. Simpson to

clarify what he meant by “gathering transportation.” App. at 1621. In response, Mr.

Simpson explained that he considers “there to be three legs of transportation in the

natural gas industry.” App. at 1622. He describes the first leg to be “gathering

transportation,” which includes moving the “gas from the mouth of the well typically

to the inlet of the gas plant but sometimes to the inlet of another pipeline.” App. at

1622. And he further indicated that his testimony was concerned with the costs

incurred during that first leg.



                                            13
      Considering that first leg of gathering transportation, Mr. Simpson testified he

had reviewed the paid history data and royalty payment statements for Subclass 1

members from July 2011 through June of 2016. The paid history data, as

Mr. Simpson explained, contains more detail about the costs incurred by WPX after

the gas leaves the well, or “post-production,” than the royalty payment statements.

By comparing these two sets of documents, Mr. Simpson determined which costs

incurred by WPX had been deducted from royalty payments and which had not. That

is, he identified post-production costs recorded in the paid history data but not also

listed as deductions on the royalty payment statements.

      Specifically, Mr. Simpson identified three categories of post-production costs

recorded in the paid history data: FUEL, BGTHRI, and MKRGT3. According to Mr.

Simpson, these categories reflected costs incurred for fuel (FUEL) and gathering

(BGTHRI) and (MKRGT3). He then reviewed the payment history for each of the

Objectors and determined that these gathering and fuel deductions had already been

subtracted by WPX from the Objectors’ royalty payments.

      Class counsel then asked Mr. Simpson to focus on the settlement as it relates

to Subclass 1 owners generally. First, Mr. Simpson explained that the settlement

included a reimbursement of 38% of the fuel costs deducted from royalty payments

prior to July 2016. Next, counsel asked Mr. Simpson to address the impact of ¶ 9.b

on Subclass 1 members. Again, Mr. Simpson compared the payment history data with

the royalty payment data to determine whether there were outstanding post-

production costs that had not previously been deducted from royalty payments and

                                           14
might, therefore, be recouped under ¶ 9.b. He concluded: “For certain individuals,

maybe for certain wells and certain time periods, there were categories of expenses

that [Mr. Simpson] believed were not deducted by TEP . . . .” App. at 1628. Mr.

Simpson identified those undeducted costs as what TEP may recoup from future

royalty payments under ¶ 9.b. TEP’s counsel then asked Mr. Simpson to estimate

those costs:

      Q: Have you had the opportunity in preparing for today’s hearing to evaluate
        any data that would identify for you how much TEP would be recouping for
        the time period covered by the settlement for all owners in connection with
        these NGL transportation and fractionation costs?

      A: I have seen the results of an analysis of that, yes.

      Q: How much is it?

      A: It amounted to $275,000 or thereabouts.

      Q: And is that specific to one subclass or is that for all owners, all 608 owners
        in the Sefcovic settlement class?

      A: That was across all categories of leases in the Sefcovic case.

      Q: Now, with respect to just subclass 1, do you know how much of that total
        $275,000 is associated with potential recoupment of overpayments to
        subclass 1 owners?

      A: What I saw was less than a thousand dollars related to subclass 1.

App. at 1629.

      Thus, Mr. Simpson testified to a recoupment calculation based on post-

production costs reflected on the paid history data records that had not already been

deducted from royalty payment statements. Those calculations resulted in a total of

$275,000 of post-production costs for all classes during the relevant time period that

                                           15
had not been deducted from royalty payments. And, of that $275,000, Mr. Simpson

testified that less than $1,000 was attributed to Subclass 1 owners.5

      Mr. Simpson’s testimony explains exactly how he calculated the potential

liability to Subclass 1 members under ¶ 9.b, and why he used that method. His

calculations were also supported by WPX’s contemporaneous records documenting

post-production costs incurred and the costs deducted from royalty payments. And

Objectors did not challenge these calculations, Mr. Simpson’s methodology, or elicit

any contrary information on cross examination.

      At oral argument on appeal, Objectors’ counsel pointed us to a portion of the

direct examination of their expert, Ms. Denomy, as evidence that the recoupment

rights under ¶ 9.b render the Sefcovic SA fundamentally unfair. Based on review of

that testimony, it is not surprising the district court was unconvinced. Although Ms.

Denomy did opine that Subclass 1 members could be liable for $4 million in

recoupment obligations, the explanation of that opinion is lacking.

      During the fairness hearing, Ms. Denomy agreed with Mr. Simpson that not all

gathering costs6 had been deducted from the royalty payments during the period



      5
         As explained, Mr. Simpson concluded that none of those unpaid amounts was
attributed to any of the Objectors.
      6
         The record does not reflect what costs Ms. Denomy included as “gathering
costs,” but there is nothing to suggest she disagreed with Mr. Simpson’s
identification of the post-production gathering costs identified as BGTHRI, and
MKRGT3 in WXP’s paid history records. And because the discussion was related to
¶ 9.b of the Sefcovic SA, it is also fair to assume she was focused on post-production
costs. See Sefcovic SA, at ¶ 9.b (allowing recoupment of “any overpayments made to
                                          16
covered by ¶ 9.b: “because there were two gathering fees listed in June of 2016 and

only one of those two [was] deducted . . . the potential for them to collect that second

gathering fee is there.” App. at 1640–41. But rather than consulting the paid history

data records to determine whether, in fact, there were any costs incurred by WPX for

post-production costs but not deducted, Ms. Denomy compared the amount WPX

deducted for gathering fees and fuel in June 2016 to the amount TEP deducted for

such fees when it took over. She then concluded, without explanation, that the

difference between the 21 cents deducted by WPX and the 59 cents deducted by TEP

“reflect[s] the difference between accounting for both of those gathering [costs].”

App. at 1641. Finally, Objectors’ counsel asked “how much could they take since this

new amount is authorized under this proposed settlement going back from class 2 and

class 3?” App. at 1642. Ms. Denomy responded, “[a]bout $4 million.” Id.

      But there is no evidence in the record explaining the increase from 21 cents to

59 cents, and certainly no evidence tying that difference to post-production costs that

might be recouped under ¶ 9.b. Nor is there any explanation why WPX would have

incurred $3.725 million in post-production costs that it did not include in its paid

history data—the $4 million claimed by Ms. Denomy, less the $275,000 calculated

by Mr. Simpson from those records. But even if the thirty-eight cent difference was

somehow relevant to post-production costs, Ms. Denomy failed to explain how she

production costs”) App. at 314.
                                           17
expanded that difference to a total recoupment liability for Subclass 1 members of $4

million.7

      The district court received conflicting testimony about an issue that was not

then central to the proceeding. Mr. Simpson explained his methodology such that his

calculations could be understood, verified, and replicated. In contrast, Objectors

offered a theory of Subclass 1 liability under ¶ 9.b based on speculation and

containing gaps in analysis that make it impossible to assess the accuracy of the

calculation. Given this meager record, Objectors have failed to meet their burden to

establish the factual basis for their objection to ¶ 9.b. As a result, we cannot conclude

the district court abused its discretion by approving a settlement agreement

containing the recoupment provision. See Miller v. Woodmoor Corp., 619 F.2d 65, 67

(10th Cir. 1980) (“The parties to the settlement supported their conclusions to the

satisfaction of the court and the objectors had every opportunity to show that the

settlement was unfair to them and their class. This is enough.”).

   4. The Parties Believed the Settlement was Fair and Reasonable

      Finally, the fourth Tennille factor asks whether the parties “believed the

settlement was fair and reasonable.” Tennille, 785 F.3d at 434. As the district court


      7
         TEP has affirmatively represented to both the district court and this court that
the recoupment it is entitled to under ¶9.b totals about $1,000 for all of Subclass 1.
And at the fairness hearing, Mr. Simpson testified that there are no post-production
costs that have not been deducted from the Objectors’ royalty payments. In the event
TEP seeks instead to recoup a greater sum from Subclass 1 members, nothing in the
Sefcovic SA precludes those members from bringing a legal action to challenge that
conduct, which would be highly suspect due to TEP counsel’s representations to the
district court.
                                           18
observed, Subclass 1 members were “aware of . . . uncertainties” in their royalty

agreements under the Lindauer SA and “believe[d] this [Sefcovic] Settlement

Agreement [was] in their best interests.” App. at 1460. Indeed, Appellees assert, and

Objectors do not dispute, that of 607 class members, only the four Objectors in this

case challenged the reasonableness of the Sefcovic SA. See Fager v. CenturyLink

Commc’ns, LLC, 854 F.3d 1167, 1175 (10th Cir. 2016) (finding no clear error in

district court’s conclusion that settlement was fair in part because “only a few class

members opted out” and only one filed an objection); Wal-Mart Stores, Inc. v. Visa

U.S.A., Inc., 396 F.3d 96, 118 (2d Cir. 2005) (“If only a small number of objections

are received, that fact can be viewed as indicative of the adequacy of the settlement.”

(quotation marks omitted)).

      In summary, the district court did not abuse its discretion in finding that the

Sefcovic SA is fair.

                            B. Adequacy of Class Representation

      Objectors next assert a variety of arguments in support of their contention that

Subclass 1 representatives did not adequately represent the interests of absent

Subclass 1 members. Because Objectors failed to raise this issue in the district court

despite ample opportunity to do so, we will not consider it on appeal.

      Parties may not preserve a challenge “by presenting the issue to the district

court in a vague and ambiguous manner.” U.S. Aviation Underwriters, Inc. v. Pilatus

Bus. Aircraft, Ltd., 582 F.3d 1131, 1142 (10th Cir. 2009) (internal quotation marks

omitted). Rather, to preserve an issue for appeal, a party must “alert[] the district

                                           19
court to the issue and seek[] a ruling.” Id. (quotation marks omitted). A fleeting

reference will not suffice. Id.; see Tele-Commc’ns, Inc. v. Comm’r, 104 F.3d 1229,

1233–34 (10th Cir. 1997) (holding a single paragraph containing a “fleeting

contention” deprived the court below “of the opportunity to analyze and rule on th[e]

issue now raised in detail for the first time on appeal”).

      Objectors say they raised the issue before the district court with the following

paragraph in their “Hearing Brief Regarding Objections to Approval of Proposed

Class Settlement”:

      The structure of this proposed settlement creates an illusory common fund
      (to be recouped by defendant from ¶9.a. deductions and without adequate
      disclosure to absent class members in the Notice), together with the
      unconscionably overbroad release of extremely valuable uncompensated
      class claims. This structure is highly suggestive of collusion, and/or
      inadequate representation. Strict scrutiny by this Court is required to
      vigilantly guard the interests of absent class members and to insure the
      “identical factual predicate” standard is complied with.
App. at 1391. This paragraph, appearing in a section challenging the scope of the

settlement agreement’s release of claims, is the extent of Objectors’ argument on

inadequate representation in the district court.

      Nonetheless, Objectors claim they preserved this argument because (1) they

“elicited testimony supporting the allegation of inadequate representation at the

Fairness Hearing itself,” Aplt. Reply Br. at 15, and (2) the district court ruled on the

adequacy of class representation. This argument is unavailing. The parties must raise

an issue to preserve it for appeal. See U.S. Aviation, 582 F.3d at 1147 (holding issue




                                           20
preserved when “[t]he parties argued, and the district court definitively ruled on, the

precise objection raised on appeal”).

       Objectors may not use the district court’s one-sentence finding that class

representatives were adequate to assert arguments on appeal that were never

presented to the district court. Nor can they rely on a fleeting reference to “and/or

inadequate representation” in a portion of a brief challenging the scope of the

settlement’s release of claims. Nothing in the Objectors’ written submissions or

argument would have put the district court on notice that it was being presented with

substantive arguments challenging the adequacy of representation. Objectors

arguments are therefore waived.

                             C. Adequacy of the Settlement Notice

       Objectors next argue they received insufficient notice of the Sefcovic SA.

Under Fed. R. Civ. P. 23(e)(1)(B), a district court approving a proposed class action

settlement “must direct notice in a reasonable manner to all class members who

would be bound by the proposal.”

       Notice in this context has two aspects: constitutional due process and the

requirements of Fed. R. Civ. P. 23. See Tennille, 785 F.3d at 436. “We review de

novo questions of notice that implicate due process,” and then “[w]ithin the bounds

of due process, . . . the form that such notice is to take is left to the discretion of the

district court.” Id. (alterations in original) (quotation marks omitted).

       The notice explained, in relevant part, as follows:



                                             21
      Plaintiffs have alleged that, at various times since July 1, 2011, TEP
      deducted or adjusted from royalties certain charges for costs that should not
      have been deducted. Specifically, Plaintiffs have asserted that TEP should
      not have deducted from Gas royalties certain costs that were not
      permissible to deduct under the terms of a class action settlement
      agreement approved by a Colorado state district court in a lawsuit
      captioned Ivo Lindauer v. Williams Production RMT Co., Case No. 2006-
      CV-0317 (Garfield County District Court) (the “Lindauer Settlement”).
      These deductions are referred to in this Notice as “Disputed Deductions.”
             ...
      Upon final Court approval, all members of the TEP Settlement Class who
      choose not to timely exclude themselves from the TEP Settlement Class
      (i.e., who do not “opt out” of the TEP Settlement Class) will receive the
      monetary benefits of the TEP Settlement and will be bound by the resulting
      Order in the Lawsuit, barring them from bringing any claim against TEP
      related to royalty calculations that are covered by the TEP Settlement
      Agreement (“Settled Claims”). If a member of the TEP Settlement Class
      does not opt out, that member will receive payment of a portion of the
      Settlement Fund as described above, and may not thereafter bring Claims.
App. at 888–90.

      The notice explained the calculation of future royalties to class members, that

recipients could opt out of the Sefcovic SA, and that remaining in the class would

result in class members receiving their share of the settlement fund and “[r]eleas[ing]

all Settled Claims” against TEP. App. at 890. The notice also gave contact

information for class counsel and provided information about how to access the full

Sefcovic SA online. App. at 892.

      Objectors do not appear to challenge the notice’s compliance with Rule 23, but

they do make a variety of objections to the notice’s specificity. They argue the notice

should have mentioned “[t]he gathering and fuel deduction claims,” the possibility

that TEP might recoup past deductions in future royalty payments, and the value or


                                           22
amount of various deductions under the Sefcovic SA. Aplt. Br. at 36–37. Objectors

also assert the notice failed to elaborate on the breadth of claims class members

would release by not opting out. Id. at 37.

       But Objectors point to no authority requiring class notice to reach that level of

specificity. The notice here described the general nature of the claims, as well as the

method TEP would use to calculate future royalty payments. The notice thus

“adequately apprised putative class members of the nature of the claims at issue.”

Tennille, 785 F.3d at 437; see also Gooch v. Life Inv’rs Ins. Co. of Am., 672 F.3d

402, 423 (6th Cir. 2012) (“All that the notice must do is ‘fairly apprise . . .

prospective members of the class of the terms of the proposed settlement’ so that

class members may come to their own conclusions about whether the settlement

serves their interests.” (alteration in original) (quoting Grunin v. Int’l House of

Pancakes, 513 F.2d 114, 122 (8th Cir. 1975))). The notice also accurately explained

that the decision to not opt out would result in the release of “any claim against TEP

related to royalty calculations that are covered by the TEP Settlement Agreement.”

App. at 890. Finally, the notice “informed putative class members how to obtain

more information about the settlement, directing them to [a] website, where they

could get a copy of the Settlement Agreement.” Tennille, 785 F.3d at 437. If any

class member desired more detail, the notice “inform[ed] class members of several

ways they could obtain additional information about the claims that they would be

releasing if they joined the settlement.” Id. Because the notice satisfied the



                                            23
requirements of Rule 23 and the constitutional demands of due process, we reject

Objectors’ contention that the class settlement notice was deficient.

                           D. The Breadth of Released Claims

     Finally, Objectors argue the Sefcovic SA contains an overly broad release. The

Sefcovic SA release provides that the class members

      release TEP and its predecessors . . . from any and all liabilities, rights,
      claims, demands, obligations, damages (including claims for or award of
      costs and/or expenses, court costs and attorneys’ fees), losses, causes of
      action in law or in equity arising from the calculation and/or payment of
      royalties and/or overriding royalties to Plaintiffs and the Class on the sale
      of natural gas, natural gas liquids, and associated hydrocarbons prior to the
      Effective Date.
App. at 1472.

      Under the identical factual predicate rule, “a court may permit the release of a

claim based on the identical factual predicate as that underlying the claims in the

settled class action.” TBK Partners, Ltd. v. W. Union Corp., 675 F.2d 456, 460 (2d

Cir. 1982); see Fager, 854 F.3d at 1175. Under this principle, “class action releases

may include claims not presented and even those which could not have been

presented as long as the released conduct arises out of the ‘identical factual

predicate’ as the settled conduct.” Wal-Mart Stores, Inc. v. Visa U.S.A., Inc., 396

F.3d 96, 107 (2d Cir. 2005) (quoting TBK Partners, Ltd., 675 F.2d at 460.) “[A] court

may release not only those claims alleged in the complaint and before the court, but

also claims which ‘could have been alleged by reason of or in connection with any

matter or fact set forth or referred to in’ the complaint.” In re Corrugated Container

Antitrust Litig., 643 F.2d 195, 221 (5th Cir. 1981) (quoting Patterson v. Stovall, 528

                                           24
F.2d 108, 110 n.2 (7th Cir. 1976), overruled on other grounds by Felzen v. Andreas,

134 F.3d 873 (7th Cir. 1998)).

      Objectors contend the “factual predicate” at issue in this lawsuit concerns only

the following: (1) allegations that TEP breached the terms of Subclass 1 leases by

deducting costs in excess of reasonable transportation costs, and (2) allegations that

TEP breached the Lindauer SA by deducting costs in excess of “the express

limitations in Section 4 of the Lindauer [SA].”8 Aplt. Br. at 30–31. Because the

Sefcovic SA releases all future claims “arising from the calculation and/or payment of

royalties and/or overriding royalties to Plaintiffs and the Class on the sale of natural

gas, natural gas liquids, and associated hydrocarbons,” Objectors contend that it

contravenes the identical factual predicate rule. We disagree.

      “[I]nherent in the nature of a class-action settlement is the release of the claims

of every class member (except those who opt out).” Fager, 854 F.3d at 1176. And

“[i]f Defendants are going to pay anything to the class members, they would insist on

a release . . . that would protect them against repeated litigation over the same subject

matter.” Id. at 1173.

      “When considering the permissibility of a release, the overlap between

elements of claims is not dispositive.” Wal-Mart Stores, Inc., 396 F.3d at 108.

Instead, we focus on the factual predicate of the settled claims. See id. (“Class




      8
      Section 4 of the Lindauer SA relates to the calculation of future royalty
payments.
                                           25
actions may release claims, even if not pled, when such claims arise out of the same

factual predicate as settled class claims.”).

       The factual predicate of this action, as stated in the Second Amended

Complaint, is that “TEP has underpaid royalties owed to [Plaintiffs] under numerous

leases and overriding royalty agreements which are subject to certain future royalty

payment provisions which are set forth in the [Lindauer SA].” App. at 1158–59. The

complaint broadly alleged that TEP had breached the Subclass I royalty agreements,

the Subclass II royalty agreements, the Subclass III royalty agreements, and the

Subclass IV royalty agreements.

       Objectors’ position, that the settled claims must be “limited to three types of

cost deductions – improper gathering, fuel[,] and excess processing cost deductions

from residue gas royalty [sic],” Aplt. Br. at 32, “takes an overly narrow view of the

factual predicate of [plaintiffs’] claims.” In re Literary Works in Elec. Databases

Copyright Litig., 654 F.3d 242, 248 (2d Cir. 2011). Although certain claims in the

Sefcovic complaint focused on erroneous deductions, “including, but not limited to,

gathering, fuel, and processing,” App. at 1176 (emphasis added), the complaint made

specific reference to various other alleged errors in TEP’s calculation and payment of

royalty obligations:

    “failing to pay royalties based upon first commercial market prices for residue
     gas,” App. at 1174

    “failing to pay royalties based upon first commercial market prices for
     marketable natural gas liquid products,” App. at 1174



                                            26
    “failing to properly account for the correct value of the natural gas liquid
     components” as required by the Lindauer SA, App. at 1175

    “failing to properly account for the selling price of . . . residue gas” as required
     by the Lindauer SA, App. at 1176

In short, the Sefcovic complaint alleged an array of errors in the calculation and

payment of royalties to the Sefcovic class based on the sale of natural gas and similar

products, and this is precisely what the release purports to cover. See App. at 1472

(releasing TEP from liability “arising from the calculation and/or payment of

royalties and/or overriding royalties to Plaintiffs and the Class on the sale of natural

gas, natural gas liquids, and associated hydrocarbons prior to the Effective Date”).

      Objectors recite a “vast universe” of claims they believe would be covered by

the subject release.9 It is doubtful that all such claims would be encompassed within

the release, but to the extent they are, we conclude they share a factual predicate with

the matters alleged in the complaint. We therefore see no error in the district court’s

approval of this release.

                                    III.   CONCLUSION

      For the reasons articulated, the district court did not abuse its discretion in

approving the Sefcovic SA. Judgment is AFFIRMED.
