T1 Third-party plaintiff Mountain States Steel, Inc. ("Mountain States"), appeals from an order granting summary judgment to third-party defendant Voest-Alpine Services & Technologies Corporation ("Voest-Al-pine"). Voest-Alpine cross-appeals the denial of its first motion for summary judgment and the trial court's refusal to award Voest-Alpine additional attorney fees. We affirm.
BACKGROUND
2 On January 19, 1994, Voest-Alpine entered into an agreement to lease a commercial building from Mountain States, said lease to commence on March 1, 1994, and to terminate twelve months later unless terminated sooner or extended pursuant to any provision of the lease agreement. The lease agreement obligated Mountain States to complete by March 1, 1994, fifteen designated improvements essential to Voest-Alpine's tenancy. Further, the lease agreement required Voest-Alpine to obtain and keep in force during the term of the lease an insurance policy insuring both Mountain States and Voest-Alpine against any lability arising out of the ownership, use, or occupancy of the leased building.
€ 3 The agreement provided that if Mountain States failed to complete the improvements to the premises on time as agreed, Voest-Alpine had the option to perform the work itself or to assist in order to keep the Mountain States improvements on time, and if Mountain States could not deliver the premises on March 1, 1994, Voest-Alpine
T4 The agreement also provided that if Voest-Alpine failed to procure and maintain the required insurance, Mountain States had the option to procure and maintain such insurance at the expense of Voest-Alpine or, in the alternative, to declare Voest-Alpine's failure to procure insurance a material breach of the lease.
15 In a subparagraph entitled "Waiver of Subrogation," the lease agreement provided that Mountain States and Voest-Alpine waived any and all rights of recovery against each other for loss or damage where such loss or damage was insured against "under any insurance policy in force at the time of such loss or damage." It further provided that upon obtaining the required policy of insurance, notice would be given to the insurance carrier of the "waiver of subrogation" and endorsements to the policy recognizing the same would be procured.
16 March 1, 1994, came and went, and Mountain States had not completed the required improvements, thus precluding Voest-Alpine from taking possession of the leased property at that time, and Voest-Alpine had not procured the required insurance. Voest-Alpine finally took possession of the premises on April 6, 1994.
T7 Meanwhile, on March 4, 1994, an accident on the subject premises seriously injured two of Voest-Alpine's employees, Mark Bakowski ("Bakowski") and Alfonse Ramirez ("Ramirez"), resulting in liability claims against Mountain States. Voest-Alpine had directed those employees to assist Mountain States in completing the required improvements on the lease premises for Voest-Al-pine's occupancy. The accident occurred while Bakowski and Ramirez were working in a "man-basket" suspended by a cable about forty feet above a concrete floor. The cable snapped, and the men plummeted to the floor, sustaining severe and permanently disabling injuries.
Bakowski and Ramirez made claims against Mountain States. Mountain States tendered the defense of these claims to Voest-Alpine under the lease agreement that obligated Voest-Alpine to provide insurance for Mountain States. Voest-Alpine refused to defend Mountain States, denying any liability and any obligation to indemnify Mountain States.
T9 Mountain States, through its own insurers, settled with Ramirez for $1,182,500 in exchange for a release of any claims Ramirez could assert against Mountain States arising from the accident. However, Bakowski filed this action against Mountain States to recover for his injuries resulting from the man-basket incident. Mountain States answered the complaint and filed a third-party action against Voest-Alpine, alleging breach of contract and indemnification because of its failure to procure insurance protecting Mountain States against such claims as agreed in the lease agreement. After mediating Ba-kowski's claims, Mountain States, through its own insurers, settled with Bakowski for $503,714, but Mountain States' third-party claim against Voest-Alpine remained pending before the trial court. 1
{10 Initially, both Mountain States and Voest-Alpine moved for summary judgment. The trial court granted Mountain States' summary judgment motion and denied Voest-Alpine's summary judgment motion, concluding that the lease commenced on March 1, 1994, and that any duties under the lease to procure insurance commenced on that date. Subsequently, both parties again moved for summary judgment. On these motions, the trial court granted summary judgment to Voest-Alpine, concluding that the "waiver of subrogation" provision contained in the lease agreement barred Mountain States' claims.
T 11 Subsequently, pursuant to a provision in the lease agreement, Voest-Alpine moved for attorney fees as the prevailing party. Voest-Alpine sought an award of $30,206.45 for fees paid to its Salt Lake attorneys and $23,637.50 paid to its Pittsburgh, Pennsylvania, attorneys. The trial court granted Voest-Alpine's motion for attorney fees in part, concluding that only $30,206.45 was rea
112 Mountain States appeals, contending that the trial court erred in granting Voest-Alpine summary judgment because the waiver of subrogation provision contained in the lease agreement did not bar Mountain States' claim. Specifically, Mountain States contends that the waiver of subrogation provision is conditional, applying in this case only if Mountain States' insurers were notified that the lease contained the waiver of subro-gation provision and recognized it in an endorsement to Mountain States' policy, and Mountain States contends that the waiver is inapplicable because these required conditions were unsatisfied.
13 Voest-Alpine cross-appeals, asserting that the trial court erred in denying its first motion for summary judgment by concluding that the lease term commenced on March 1, 1994, instead of April 6, 1994, when Voest-Alpine took possession of the leased premises. Specifically, Voest-Alpine contends that because the lease did not actually commence until Voest-Alpine took possession on April 6, 1994, it was not required to procure insurance until that date, and Voest-Alpine is therefore not contractually liable to Mountain States for the settlement amounts Mountain States paid to Bakowski and Ramirez. Additionally, Voest-Alpine argues that the trial court abused its discretion in reducing the attorney fee award contained in the proposed judgment when the proposed judgment was supported by an affidavit.
STANDARD OF REVIEW
114 Summary judgment is appropriate when "there is no genuine issue as to any material fact and ... the moving party is entitled to a judgment as a matter of law." Utah R. Civ. P. 56(c); see also Ault v. Holden,
ANALYSIS
I. DATE LEASE COMMENCED
115 The first issue on appeal is whether the trial court erred in holding that the lease agreement executed by Voest-Al-pine and Mountain States commenced on March 1, 1994. According to the lease agreement, Voest-Alpine was required to "obtain and keep in force during the term of this lease" an insurance policy that insured both Mountain States and Voest-Alpine against any liability arising out of the ownership, use, or occupancy of the leased premises, which the trial court concluded would have covered the injuries of Bakowski and Ramirez.

(Emphasis added.) If the lease term did not commence on or before March 4, 1994, the date of the man-basket incident that injured Bakowski and Ramirez, then Voest-Alpine would have no obligation to Mountain States for the settlement amounts paid to Bakowski and Ramirez because Voest-Alpine's contractual obligation to purchase liability insurance would not have been in effect on that date. Voest-Alpine contends that the lease term did not commence until Mountain States actually delivered possession of the premises. The parties do not dispute that Mountain States did not deliver
{116 The date on which the lease term commenced is a matter of contract interpretation. When interpreting a contract, a court first looks to the contract's four corners to determine the parties' intentions, which are controlling. Cent. Fla. Invs., Inc. v. Parkwest Assocs.,
{17 In the instant case, the contract language with respect to when the lease began is clear and unambiguous. Paragraph 2 of the lease agreement provides:
21. Term.
The term of this lease shall be for a period commencing on the ist day of March, 1994, and terminating twelve (12) months thereafter, unless sooner terminated or extended pursuant to any provision hereof.
According to the plain language of paragraph 2.1, the lease term commenced on March 1, 1994, and was to terminate twelve months later unless extended by the lease agreement itself. In the event that the premises were not ready for Voest-Alpine's possession on March 1, 1994, another provision of the lease provides Voest-Alpine a remedy. Paragraph 2.8 states in pertinent part:
2.3. Delay in Commencement.
The parties acknowledge that time is of the essence of this lease, particularly with respect to completion of improvements and commencement of occupaney. [Mountain States] agrees to make the improvements . set forth in Exhibit "C" and its attachments pursuant to the schedule for completion set forth therein .... If [Mountain States] fails to comply in any respect with the Completion Schedule, [Voest-Alpine] may, at its sole option, perform or cause to be performed any work or service and purchase or acquire any materials necessary to keep the [required improvements] on schedule. ... If for any reason, [Mountain States] cannot deliver possession of the premises to [Voest-Alpine] on March 1, 1994, [Voest-Alpine] shall not be obligated to pay rent ... until possession is delivered. Possession cannot be delivered until the completion of item numbers 2, 3, 6, 8, 9, 10, 11, and 15 of Attachment 1 to Exhibit "C".
(Emphasis added.)
118 This paragraph does not extend or alter the commencement date of the lease. Rather, paragraph 2.3 suspends only Voest-Alpine's duty to pay rent until possession is delivered in the event of delay. While the caption to paragraph 28 reads "Delay in Commencement," the words are meaningless inasmuch as paragraph 15.5 unequivocally states that the "captions are not a part of this lease."
120 Therefore, the trial court correctly concluded that the lease term commenced on March 1, 1994. Consequently, paragraph 6.1 of the lease required Voest-Alpine to procure insurance that would have insured Mountain States for claims arising out of the ownership, use, or occupancy of the leased premises.
II. WAIVER OF SUBROGATION
{121 The next issue on appeal is whether the trial court erred in granting Voest-Alpine summary judgment when it concluded that the waiver of subrogation clause of paragraph 6.4 of the lease agreement bars Mountain States "from bringing this action to recover the sums it" paid to Bakowski and Ramirez. Specifically, the trial court concluded that while Voest-Alpine was contractually obligated to obtain insurance that would have covered the injuries suffered by Bakowski and Ramirez, Mountain States waived the subrogation rights of its insurers by agreeing to paragraph 6.4 of the lease agreement. Paragraph 6.4 of the lease agreement provides:
Warwer of Subrogation. [Voest-Alpine] and [Mountain States] each waive any and all rights of recovery against the other, or against the officers, employees, agents and representatives of the other, for loss of or damage to such waiving party or its property or the property of others under its control where such loss or damage is insured against under any insurance policy in force at the time of such loss or damage. [Voest-Alpine] and [Mountain States] shall, upon obtaining the policies of insurance required hereunder, give notice to the insurance carrier or carriers that the foregoing mutual waiver of subrogation is contained in this lease, and shall obtain endorsements to the respective policies recognizing the waiver.
The court further concluded that Mountain States waived its insurers' subrogation rights regardless of whether notice was ever given to those insurers because "[the notice provision of the waiver of subrogation clause does not create any conditions precedent to the applicability of the waiver of subrogation clause."
$22 Subrogation is a doctrine conceived in equity that " 'allows a person or entity [that] pays the loss or satisfies the claim of another under a legally cognizable obligation or interest to step into the shoes of the other person and assert that person's rights'" State Farm Mut. Auto. Ins. Co. v. Northwestern Nat'l Ins. Co.,
€23 An insurer's subrogation right to recover from a responsible third party the amount the insurer paid to or on
Because an essential element of subrogation is that the insured have a viable claim against a third party, the insured's enforceable pre-loss release of any right to hold a particular third party responsible for damages in a given cireumstance has the effect of preventing the insurer's sub-rogation rights from ever arising upon its payment of that loss to the insured. Accordingly, an insured may defeat an insurance company's rights of subrogation by entering into an agreement of release with the [third party] before or after the policy is issued, but prior to loss.
Couch § 224:76 (footnotes omitted).
1 24 The rule allows contracting parties to retain their autonomy in making and executing contracts, including agreements releasing each other from liability; it also allows insurers to protect themselves from such waivers of subrogation: Insurers can protect themselves by (1) inserting an exclusion into their policies that permits the insurer to deny coverage if an insured waives the insurer's subrogation rights, (2) raising premiums to offset outlays incurred from the loss of their subrogation rights, (8) investigating whether a potential insured has already waived any subrogation rights, (4) requiring insureds to warrant at the time a policy is issued that the insured has not, and will not, waive the insurers' subrogation rights, and (5) obtaining reinsurance to cover any waiver of subrogation rights.
126 Paragraph 6.4 of the lease agreement provides:
Waiwer of Subrogation. [Voest-Alpine] and [Mountain States] each waive any and all rights of recovery against the other, or against the officers, employees, agents and representatives of the other, for loss of or damage to such waiving party or its property or the property of others under its control where such loss or damage is insured against under any insurance policy in force at the time of such loss or damage. [Voest-Alpine]l and [Mountain States] shall, upon obtaining the policies of insurance required hereunder, give notice to the insurance carrier or carriers that the foregoing mutual waiver of subrogation is contained in this lease, and shall obtain endorsements to the respective policies recognizing the waiver.
Mountain States contends that this paragraph does not waive the subrogation rights of its insurers because (1) the waiver of subrogation was conditional and the conditions precedent were not met, and (2) paragraph 6.4 applies only to insurance required by the lease.
127 First, Mountain States asserts that the first sentence of paragraph 6.4 does not independently effectuate a waiver of subrogation, but is inextricably connected to the second sentence, which "ensures" a waiver of subrogation. However, Mountain States continues, the second sentence conditions the applicability of the waiver on notice to the insurance carrier that the lease agreement waives subrogation and on the insurer's recognizing the waiver in endorsements to the relevant insurance policies. It is undisputed that Mountain States' insurers did not endorse the waiver.
128 However, the first sentence of paragraph 6.4 independently effectuates a waiver of subrogation. That sentence unequivocally provides that Mountain States and Voest-Alpine mutually "waive any and all rights of recovery against the other ... for loss of or damage to such waiving party ... where such loss or damage is insured against under any insurance policy in force at the time of such loss or damage." (Emphasis added.) According to the plain language, Mountain States waived all causes of action against Voest-Alpine to recover for damages that were paid under any insurance policy. See Richmond Steel, Inc.,
1 29 As for the second sentence, it does not summarily invalidate the waiver if notice was not afforded to Mountain States' insurers or if the insurers did not endorse the waiver. Indeed, this sentence requires that notice be afforded to insurers and that those insurers recognize the waiver in endorsements to the respective policies, but paragraph 6.4 does not condition the validity of the waiver of subrogation upon the provision of notice or upon the procurement of the required endorsements. In other words, the waiver is independent of the lease's notice and endorsement requirements.
30 Second, Mountain States argues that the waiver of subrogation applies only to insurance required by the lease. However, according to its plain language, the first sentence of paragraph 6.4 applies to any insurance, regardless of whether that insurance is required by the lease. Mountain States ex
131 Moreover, Mountain States' insurance is arguably "required by the lease." Mountain States had the option to purchase insurance at Voest-Alpine's expense if Voest-Alpine failed to procure the required insurance. Because Mountain States used its insurance to pay for the injuries as a substitute for insurance that it asserts Voest-Alpine was required to purchase under paragraph 6.1, it appears that Mountain States exercised the option irrespective of whether the insurance was purchased before or after March 1, 1994, when the lease commenced. Therefore, because an insurance policy covered these injuries, Mountain States waived its and its insurers' rights to recover against Voest-Alpine.
132 In sum, paragraph 6.4 validly waived the subrogation rights of Mountain States' insurers. Thus, the trial court correctly granted summary judgment to Voest-Alpine on the subrogation claim.
III. ATTORNEY FEES
¶ 83 The final issue on appeal is whether the trial court abused its discretion in awarding Voest-Alpine $30,206.45 in attorney fees instead of $38,880. The trial court has broad discretion in determining what constitutes a reasonable attorney fee once it has been determined that a party is legally entitled to a fee award, and we will not reverse a trial court's determination of whether a fee is reasonable absent an abuse of discretion. R.T. Nielson Co. v. Cook,
134 In Utah, "attorney fees are generally not recoverable 'unless authorized by statute or contract'" Miller v. USAA Cas. Ins. Co.,
185 In this case, after the trial court granted Voest-Alpine's motion for summary judgment, Voest-Alpine moved for attorney fees in the amount of $30,206.45 for its Salt Lake counsel and $23,637.50 for its Pitts, burgh counsel.. In a signed memorandum decision dated September 11, 2000, the trial court awarded attorney fees for Voest-Al-pine's Salt Lake counsel only and explained:
This Court has carefully reviewed both affidavits submitted for attorney fees. [Voest-Alpine's] claim [to attorney fees for its Salt Lake counsel is based upon! a reasonable expenditure of time ... on a case of this complexity. The hourly rates assessed are well within the fees normally charged in this area for this type of litigation. The total bill [charged by Voest-Alpine's Salt Lake counsel] of $30,206.45[ ] represents a reasonable fee incurred in the defense of the third[-Iparty action maintained by [Mountain States]... .
In connection therewith, the trial court ordered Voest-Alpine's counsel to prepare "appropriate findings and a judgment." While preparing the judgment as directed, Voest-Alpine's counsel discovered that Voest-Al-pine's original motion for attorney fees "inadvertently" omitted $8,178.55 due to an alleged arithmetic error and a change in billing systems. To correct the error, Voest-Alpine submitted to the trial court proposed findings of fact and conclusions of law stating that Voest-Alpine actually incurred a total of $38,380 in attorney fees defending this litigation, which were supported by affidavits, and Voest-Alpine submitted a proposed judgment awarding Voest-Alpine attorney fees in that amount. Before signing the proposed documents, the trial court corrected both
'I 36 On appeal, Voest-Alpine contends that the trial court abused its discretion by failing to award Voest-Alpine the augmented attorney fee of $38,880 when this increased award was supported by affidavits in the record, this amount constituted a reasonable fee, and the trial court failed to explain why it refused to award the additional $8,178.55.
137 The trial court did not abuse its discretion in awarding only $30,206.45. Before Voest-Alpine submitted the proposed judgment awarding Voest-Alpine the increased amount, the trial court determined, with explanation, that $30,206.45 was reasonable and ordered Voest-Alpine's counsel to prepare a judgment awarding Voest-Alpine attorney fees in conformity with that ruling. See Utah R. Jud. Admin. 4-504(1) (providing that party must "file with the court a proposed order, judgment, or decree in conformity with the ruling." (emphasis added)). By unilaterally submitting a proposed award that increased the award from the trial court's ruling, Voest-Alpine attempted to obtain an unauthorized attorney fee award in an amount that the trial court never determined was reasonable. See id. Such attempt to increase a fee award is at best unorthodox, at worst furtive. The unilateral alteration verges on an attempt to cireumvent the trial court's orders and determinations. The trial court did not abuse its discretion by correcting the proposed findings of fact and conclusions of law and the proposed judgment to conform to the court's original award of $30,206.45, thereby maintaining its own discretion, control, and authority over attorney fee awards.
138 Moreover, a trial court is not required to adopt the prevailing party's assertion of what constitutes a reasonable attorney fee, even if the fee sought is supported by an affidavit. In Dixie State Bank, we explained that a "trial court is allowed to reduce the amount asserted by one party in determining a reasonable fee" and that the trial court is not required to accept self-interested evidence regarding the reasonableness of an asserted fee.
139 Further, the party moving for attorney fees in reliance on its own imprecise and erroneous calculations must carry the burden of following the proper procedural course of filing an amended motion for attorney fees to redress its mistake or be responsible for and suffer the consequences of the error. In this case, Voest-Alpine inappropriately assumed that the trial court would tacitly acquiesce in the proposed augmented attorney fees award without first ruling on the reasonableness of the increased award simply because the proposed findings of fact and conclusions of law and the proposed judgment were accompanied by an affidavit supporting the award. Instead, Voest-Alpine should have filed an amended motion for attorney fees or a motion to augment the attorney fee award, let the trial court decide whether $38,380 was a reasonable fee, and then-should the trial court increase the award-prepare a proposed judgment in conformity with the court's revised decision. Seq, eg., ProMax Dev. Corp. v. Raile,
CONCLUSION
140 The trial court correctly concluded that the lease term commenced on March 1, 1994, and that the waiver of subrogation in the lease precluded Mountain States' claims. Additionally, the trial court did not abuse its discretion by refusing to award Voest-Alpine additional attorney fees. We therefore affirm.
Notes
. Mountain States' own insurers, having settled and paid Bakowski and Ramirez, pursue this matter under their subrogation rights in Mountain States' name.
. On appeal, neither party raises the status of Bakowski and Ramirez for purposes of the Workers' Compensation Act, and we therefore do not address it in this opinion.
