ORDER AFFIRMING IN PART AND VACATING IN PART ARBITRATION AWARD [22, 23]

I. INTRODUCTION

This case concerns withdrawal liability under the Employee Retirement Income Security Act of 1974 (“ERISA”) and the Multiemployer Pension Plan Amendments Act of 1980 (“MPPAA”). Quad/Graphics, Inc. (“Quad”) ceased contributing to a mul-tiemployer pension plan called GCIU-Em-ployer Retirement Fund (“Fund”). The MPPAA imposes liability on employers that withdraw from multiemployer pension plans, and thus the Fund calculated Quad’s withdrawal liability and demanded payment. Quad disputed the Fund’s calculation on several grounds, prompting the parties to submit the matter to arbitration. See 29 U.S.C. § 1401 (a)(1). The arbitration recently concluded, and both parties now petition this Court to affirm and vacate opposing portions of the arbitration award. (ECF Nos. 22, 23.) For the reasons discussed below, the Court AFFIRMS IN PART and VACATES IN PART the arbitrator’s final award, and DISMISSES AS MOOT the Fund’s challenge to portions of the arbitrator’s final award.

II. BACKGROUND

A. Statutory Background

Collective bargaining agreements (“CBAs”) between an employer and an employee-union often require the employer to provide pension benefits to its employees. To ensure that these employees actually receive their promised benefits, ERISA requires the employer to contribute to a pension plan in an amount sufficient to cover those benefits. Moreover, where the plan is a multiemployer plan (as opposed to a single-employer plan), the MPPAA requires withdrawing employers to pay their share of the plan’s unfunded vested benefits. This ensures that employer withdrawals do not bankrupt the plan. See generally Milwaukee Brewery Workers’ Pension Plan v. Joseph Schlitz Brewing Co., 513 U.S. 414, 416 , 115 S.Ct. 981 , 130 L.Ed.2d 932 (1995).

A withdrawal is either partial or complete. 29 U.S.C. § 1381 (a). A withdrawal is partial when the employer’s obligation to contribute to the plan ceases under some, but not all, of the CBAs by which it is bound. Id. § 1385(a)(2), (b)(2)(A). A withdrawal is complete when the employer’s obligation to contribute to the plan ceases under all CBAs by which it is bound. Id. § 1383(a)(1). 1 Moreover, withdrawal liabili *555 ty is assessed based on the. “plan year” in which the employer withdraws, see id. § 1391, and the extent of the employer’s liability can change substantially based on the particular plan year in which .the withdrawal occurs.

B. Factual Background

Quad is an employer in the commercial printing business. (Arbitration Record (“AR”) at 9, ¶ 2.) Quad maintains facilities at multiple locations within the United States, and is bound by separate CBAs at each of those facilities. (Id. at 9, ¶ 4.) One of Quad’s facilities is located in Versailles, Kentucky. (Id. at 9, ¶ 5.) In 2007, Graphic Communications Conference, International Brotherhood of Teamsters, Local 826-C (“Local 826-C”) was the exclusive bargaining representative for the Versailles employees. (See id. at 349.) That year, Local 826-C entered into a CBA with Quad’s predecessor, World Color (USA), formerly known as Quebecor World (USA), Inc. (“Quebecor”). (Id. at 349-411.) Quad acquired Quebecor in 2010, and the parties appear agree that Quad assumed Quebe-cor’s obligations under the CBA. (Id. at 9, ¶ 3.)

The Versailles CBA contained two provisions relevant to the parties’ dispute. The. first concerned the manner in which employee vacation time accrued and was used. Under the CBA, employees received their yearly allotment of vacation time in a “bank” at the beginning of the year. (Id. at 12, ¶ 28.) Employees could use their vacation time at any time throughout the year, up until the end of the day on December 31. (Id. at 10, ¶ 8; id. at 12, ¶¶ 29-31.) Any unused vacation time left in the banks thereafter must be paid out to the employee by January 31. (Id. at 10, ¶ 9.) Thus, for example, if John Doe accrued 20 hours of vacation time over the course of 2008, Quad would credit 20 hours of vacation time in John’s bank at the beginning of 2009, John could use this vacation time at any point up to December 31, 2009. Any unused vacation time left in the bank at the end of this period must be paid out to= John on or before January 31,2010.

The other relevant CBA provision concerned the timing of pension benefit payments. Under the CBA, Quad was required to make monthly contributions to the Fund. (Id. at 9-10, ¶7.) The CBA required Quad to calculate its monthly contribution obligation based on, inter alia, the hours worked by the employee that month and vacation time taken by (or paid out to) the employee that month. (Id.) Thus, the January payout of the previous year’s unused vacation time triggered Quad’s obligation to contribute to the Fund.

In December 2010, the Versailles employees voted to decertify Local 826-C as their exclusive bargaining representative. (Id. at 10, ¶ 11.) The National Labor Relations Board (“NLRB”) certified the results of the election on December 27, 2010. (Id.) As of January 1, 2011, there were over 5,000 Hours of total unused vacation time in the banks of Versailles employees. (Id. at 12, ¶ 33.) Quad paid out this vacation time to the Versailles employees on January 21, 2011, in the total amount of $84,953.62. (Id, at 13, ¶ 38.) On January 11, 2011, Quad submitted its contribution payment to the Fund for its Versailles employees in the amount of $48,445.20. This payment was for work performed and contributions due in December 2010. (Id. at 10, ¶ 14; id. at 13, ¶ 36.)

Because the decertification voided the CBA—and therefore cut off Quad’s obligation thereunder to contribute to the Fund—Quad notified the Fund of the de-certification. (Id. at 10, ¶ 13.) While calculating Quad’s withdrawal liability, the Fund concluded that Quad’s contribution obligation under the Versailles CBA *556 ceased in 2010. 2 (Id, at 11-12, ¶ 27; id. at 14, ¶¶ 45-46.) The Fund also concluded that Quad’s contribution obligation under the CBAs governing Quad’s other facilities ceased in 2011 (except for the Memphis facility, which previously withdrew in 2009). (Id. at 11-12, ¶27.) Ás a result, the Fund assessed liability for a 2010 partial withdrawal (for the Versailles facility), and a 2011 complete withdrawal. (Id. at 10, ¶ 15; id. at 11, ¶ 17.) Quad disputed that its obligation to contribute under the Versailles CBA ceased in 2010, and thus argued that the Fund should not have assessed liability for a 2010 partial withdrawal. (See id. at 11, ¶ 18.) The allegedly erroneous assessment increased Quad’s-total withdrawal liability by approximately $20 million. (Id. at 13, ¶ 42.) Finally, in assessing Quad’s liability for the 2011 complete withdrawal, the Fund applied a partial withdrawal credit (for the 2009 Memphis partial withdrawal) before applying the MPPAA’s 20-year payment cap on withdrawal liability. (Id. at 15, ¶¶ 65-56.) Quad contends that the Fund should have applied the 20-year cap before the partial withdrawal credit, and that the Fund’s failure to do so increased its 2011 withdrawal liability by approximately $14 million. (Id. at 1639.)

C. Arbitration Proceedings

The parties presented three issues to the arbitrator for decision. The two issues pertinent to this action are: (1) whether Quad’s obligation under the Versailles CBA to contribute to the Fund ceased in 2010 or 2011; and (2) in calculating Quad’s withdrawal liability, whether the Fund properly applied the partial withdrawal credit before applying the 20-year cap. (Id. at 4-5i) 3 '

On the first issue, the arbitrator concluded that Quad’s obligation under the Versailles CBA to contribute to the Fund ceased in 2011. The arbitrator reasoned that: (1) the Versailles CBA required Quad to pay out all unused vacation and personal time to its employees from 2010; (2) vacation days could be used up until midnight on January 1, 2011; (3) Quad therefore could not calculate (and thus could not pay out) any unused vacation time to its employees until thereafter; and thus (4) Quad’s obligation to contribute to the Fund based on those payments did not cease until 2011. (See id. at 12-13, ¶¶ 31, 34, 35, 39; id. at 18-21.) On the second issue,' the arbitrator concluded that the wording and structure of the various statutes under the MPPAA supported' the Fund’s decision to apply the partial withdrawal credit before applying the 20-year payment cap. (Id. at 21-23,¶¶ 8-15.)

At the conclusion of the arbitration proceeding, both Quad and the Fund moved for an award of attorneys’ fees based on the other’s bad faith conduct during the proceedings. (Id. at 24-25, ¶¶22.) Quad argued that: (1) the Fund lacked a. good faith basis for seeking an additional evi-dentiary hearing on the second issue put before the arbitrator; and (2) the Fund lacked a good faith basis for attempting to *557 submit several revised withdrawal assessments that were purposely inconsistent with the arbitrator’s rulings. (Id.) The Fund, in turn, argued that Quad lacked a reasonable basis on which to assert the second issue regarding the sequence of withdrawal liability adjustments. (Id.) The arbitrator concluded (without explanation) that neither Quad nor the Fund had engaged in bad faith conduct, and thus denied their respective requests for fees and costs. (Id, at 25, ¶ 24.) Finally, the arbitrator also denied the Fund’s motion to delay issuance of the Anal arbitration award based on Quad’s “unclean hands.” (Id. at 24, ¶ 21.)

D. Civil Action

On May 17, 2016, the arbitrator issued his final award addressing alljssues raised in the arbitration. (Id. at 2.) Both parties immediately filed separate civil actions to affirm and/or vacate the arbitrator’s decision, which the Court consolidated into one action. (EOF No. 19.) On August 17, 2016, both parties timely moved to affirm and/or vacate the arbitrator’s decision. (EOF Nos. 22, 23.) On November 21, 2016, the Court heard oral argument from the parties on their respective Motions, after which the Court took the.Motions under submission. (ECF No. 34.) Those Motions are now before the Court for decision..

III. ISSUES PRESENTED

The parties seek to affirm and/or vacate various portions of the arbitrator’s final award. The Court rules on each issue as follows:

(1) Quad asks this Court to affirm, and the Fund asks this Court to vacate, the arbitrator’s decision that Quad’s Versailles facility withdrew from the Fund in 2011 rather than 2010. The Court VACATES the arbitrator’s decision.

(2) The Fund asks this Court to vacate the arbitrator’s decision that the Fund prepare only a revised 2011 complete withdrawal liability assessment. The Court DISMISSES AS MOOT the Fund’s challenge to the arbitrator’s decision.

(3) Quad asks this Court' to vacate, and the Fund asks this Court to affirm, the arbitrator’s decision that the Fund properly applied the partial withdrawal credit before applying the 20-year payment cap to the 2011 complete withdrawal assessment. The Court AFFIRMS the arbitrator’s decision.

(4) Quad asks this Court to vacate the arbitrator’s decision denying Quad’s request for an award of attorneys’ fees and costs against the Fund. The Court VACATES the arbitrator’s decision.

(5) Quad asks this Court to affirm the arbitrator’s decision denying,-the Fund’s request for a delay in issuing the final arbitration award based on Quad’s “unclean hands.” The Court AFFIRMS the arbitrator’s decision.

IV. STANDARD OF REVIEW

An arbitrator’s conclusions of law are reviewed de novo. Penn Cent. Corp. v. W. Conference of Teamsters Pension Trust Fund, 75 F.3d 529, 533 (9th Cir. 1996). An arbitrator’s factual findings, however, are presumed correct, “rebuttable only by a clear preponderance of the, evidence.” 29 U.S.C. § 1401 (c). While the question “[w]hether a withdrawal within the meaning of the statute has- occurred presents a mixed question of law and fact,” Penn Cent. Corp., 75 F.3d at 533 , “[t]he construction of the CBA is a question of law that [is] reviewed] de novo.” Nw. Adm’rs, Inc. v. San Bruno Garbage Co., 312 Fed.Appx. 916 , 918 (9th Cir. 2009) (citing Sania Monica- Culinary Welfare Fund v. Miramar Hotel Corp., 920 F.2d 1491, 1493 (9th Cir. 1990)); see also Nw. Adm’rs, Inc. v. B.V. & B.R., Inc., 813 F.2d 223 , 225 (9th Cir. 1987) (interpretation of the written *558 terms of a CBA is a question of law to the extent that the language is not ambiguous). Finally, “an award of attorneys’ fees is reviewed for an abuse of discretion.” Penn Cent. Corp., 75 F.3d at 535 ; see also Trs. of Utah Carpenters’ & Cement Masons’ Pension Trust v. Loveridge, 567 Fed.Appx. 659, 662 (10th Cir. 2014).

y. DISCUSSION

A. Issue 1: Quad’s Withdrawal Under the Versailles CBA

The Fund argues that the arbitrator erred in concluding that Quad’s obligation to contribute to the Fund survived the decertification of Local 826-C. The Fund argues for a bright line rule that any obligation under a CBA to contribute to a pension plan ceases immediately upon NLRB confirmation of the decertification vote. Any other rule, the Fund contends, would create uncertainty and litigation in an area of law that emphasizes administrative uniformity and simplicity. Quad, on the other hand, argues that whether an employer’s obligation to contribute to a pension plan survives decertification depends on the terms of the specific CBA at issue. Here, because Versailles employees could take vacation any time up until January 1, 2011, it was impossible to determine before that date the amount of unused vacation time Quad would need to pay out. Moreover, because the CBA required Quad to contribute to the Fund based on the payment of unused vacation time, Quad argues that its obligation to contribute to the Fund did not cease until at least January 1, 2011. For the reasons discussed below, the Court concludes that Quad’s obligation to contribute to the Fund under the Versailles CBA ceased immediately upon NLRB confirmation of the decertifi-cation vote.

An employer partially withdraws from a pension plan during a particular plan year “if, during such year, the employer permanently ceases to have an obligation to contribute under one or more but fewer than all collective bargaining agreements under which the employer has been obligated to contribute under the plan.” 29 U.S.C. § 1385 (b)(2)(A)(ii). Because the Fund’s plan year ran from January 1 to December 31, the key issue is whether Quad “permanently cease[d] to have an obligation to contribute” to the Fund under the Versailles CBA during the 2010 calendar year or the 2011 calendar year.

The Ninth Circuit has held that decerti-fication of an employee union prospectively voids any CBA between that union and the employer, and thus cuts off any obligation under the CBA to contribute to a pension plan. Sheet Metal Workers’ Int’l Ass’n, Local 206 of Sheet Metal Workers’ Int’l Ass’n, AFL-CIO v. W. Coast Sheet Metal Co., 954 F.2d 1506, 1509-10 (9th Cir. 1992) (citing Sheet Metal Workers Int’l Ass’n, Local No. 162 v. Jason Mfg., Inc., 900 F.2d 1392, 1400 (9th Cir. 1990)); see also MacKillop v. Lowe’s Mkt., Inc., 58 F.3d 1441 , 1446 (9th Cir. 1995) (“Sheet Metal Workers’ holds that the voluntary decertification of a union by its employees ends the collective bargaining agreement, and employer obligations to the ERISA plans cease upon that event.”); Laborers Health & Welfare Trust Fund for N. Cal. v. Westlake Dev., 53 F.3d 979, 984 (9th Cir. 1995) (“The obligation to contribute to the Trust Funds depends upon the existence of employment covered by the CBA. Once the CBA was lawfully repudiated, there was no longer any covered employment and thus there was no duty on Westlake’s part to contribute to the Trust Funds.”); Laborers Health & Welfare Trust Fund For N. Cal. v. Advanced Lightweight Concrete Co., 484 U.S. 539, 553 , 108 S.Ct. 830 , 98 L.Ed.2d 936 (1988) (noting in dicta that absent a statutory obligation to the contrary, there “would [be] no basis whatsoever for claiming that an employer had any duty to *559 continue making contributions to a fund after the expiration of its contractual commitment to do so”). 4 The court reasoned that “[a] contract to contribute to a trust fund of a [ujnion with which [the employer] has no ongoing collective bargaining relationship makes no sense,” because “trust fund provisions have no legal effect when the [u]nion is no longer the certified representative of [the] employees.” W. Coast Sheet Metal Co., 954 F.2d at 1509 ; see also id. (“[B]ecause the collective bargaining agreement became inoperative prospectively, it thereafter had no force or legal effect. Legal obligations have their source either in authority acting within its proper jurisdiction or in contract properly executed and currently effective. Here neither source exists.”). The court also noted that it is unfair to force an employer to contribute to the pension plan of a uniop that no longer represents its employees, for such contributions could benefit only the employees of other employers. Id. at 1510 . Similarly, the Fifth Circuit, relying on West Coast Sheet Metal, has held that decertification prospectively voids a CBA. Pioneer Nat. Res. USA, Inc. v. Paper, Allied Indus., Chem. And Energy Workers Int’l Union Local 4-487, 338 F.3d 440, 441 (5th Cir. 2003). 5 The Fifth Circuit further held that one consequence of decertification is that “employees los[e] all job protection under the CBA. With no promise of continued employment, they c[an] be discharged as at-will employees.” Id.

Quad points to dicta in West Coast Sheet Metal suggesting that a contribution obligation under a CBA might survive decerti-fication if the CBA specifically provided for such survival. 954 F.2d at 1509 (“We find nothing in the language of the renewal contract that obligates West Coast to continue to contribute to the Trust Funds after the Union’s decertification.”). Quad argues that this is in line with cases from the Supreme Court and other circuit courts holding more generally that CBA provisions can survive expiration of the CBA in certain circumstances. For example, in Litton Fin. Printing Div. v. N.L.R.B., the Supreme Court held that while “an expired contract has by its own terms released all its parties from their respective contractual obligations,” there are “[e]xceptions [that] are determined by contract interpretation.” 501 U.S. 190, 206 , 111 S.Ct. 2215 , 115 L.Ed.2d 177 (1991). Such exceptions include “[Flights which accrued or vested under the agreement,” and rights that the parties clearly intend to survive termination of the CBA, Id. The Court went on to hold that a provision in a CBA specifying the framework employers must use to lay off employees was not intended to survive termination of the agreement, because the framework was *560 based on- factors that could not possibly remain constant following the termination. Id. at 209-10 , 111 S.Ct. 2215 . Similarly, the First Circuit has held that earned vacation time survives termination of a CBA because those benefits accrue to the employee during the life of the CBA. United Parcel Serv., Inc. v. Union De Tronquistas De Puerto Rico, Local 901, 426 F.3d 470, 473-74 (1st Cir. 2005) (“Vacation time strikes us as the classic example of a benefit that—barring explicit provision to the contrary—accrues during the term of the agreement under which it is earned.”).

The Court declines to decide whether decertification always and immediately terminates any contribution obligation under a CBA, because even if it does not, nothing in the Versailles CBA specifically extended Quad’s obligation to contribute to the Fund into 2011. The three relevant provisions under the Versailles CBA are: (1) employees may take vacation time at any time between January 1 to December 31; (2) any unused vacation time remaining after this period will be paid out by January 31 of the following year; and (3) contributions to the Fund must be made based on such end-of-year vacation time payouts. However, the CBA does not explicitly provide that any of these obligations continue past expiration or termination of the CBA. Moreover, there is nothing implicit in the nature of these obligations that compels such a conclusion. The mere fact that the CBA imposes an obligation to occur at some point in the future does not mean that the obligation will survive if the CBA terminates before then; any other rule would create significant line-drawing issues. Indeed, CBAs by their very nature contemplate performance of all obligations thereunder for a defined period of time (e.g., payment'of wages, regulation-'of working -conditions, etc.), yet no one suggests that all of those obligations must remain in effect if the CBA terminates early. 6 Cf. Pioneer Nat. Res. USA, 338 F.3d at 441 (“When the Union was decertified, [its] employees lost all job protection under the CBA.”). In short, there is nothing to distinguish these obligations from the myriad other obligations under the CBA that clearly did not survive decertification.'

Thus, the fact that the CBA provides that employees can take vacation at any time before the end of 2010 does not mean that they may still do so if the CBA terminates before the end of the year. Instead, once the agreement terminates, this provision ceases to exist and is no longer enforceable. As a result, any vacation time remaining in the employees’ banks upon decertification constitutes the total unused vacation time that Quad owes its employees—at least as far as the CBA is concerned. Because of this, the CBA no longer imposed an obligation to contribute to the Fund that Quad could fulfill only after January 1, 20ll; Quad could fulfill its obligation to contribute to the Fund based on unused vacation time in December 2010. And because there is no dispute that the obligation to contribute under the Versailles CBA ceased when the unused vacation time payouts could be paid rather than when they were actually paid, Quad’s Versailles, facility partially withdrew from the Fund during the 2010 plan year. 7

Both Quad and. the arbitrator rely on the Supreme Court’s opinion in Nolde *561 Bros., Inc. v. Local No. 358, Bakery & Confectionery Workers Union, AFL-CIO, 430 U.S. 243 , 97 S.Ct. 1067 , 51 L.Ed.2d 300 (1977), but that case does not require a different result. There, the Supreme Court held that certain types of arbitration provisions in a CBA are presumed to survive its expiration unless the CBA specifically provides otherwise. Id. at 254 , 97 S.Ct. 1067 . The Court reasoned that the liberal federal policy favoring arbitration generally and arbitration of collective bargaining disputes in particular warranted such a presumption. Id. The CBA provisions at issue here, however, do not involve arbitration. For provisions not relating to arbitration, the presumption regarding survivability is reversed: such provisions do not survive expiration of the CBA unless a recognized exception applies. See Litton, 501 U.S. at 206 , 111 S.Ct. 2215 . Quad also does not point to any comparable policy favoring survival of the disputed provisions—indeed, Quad spends much of its briefing arguing that policy concerns should not change the outcome here. Thus, the .Court finds Nolde Brothers unpersuasive.

For these reasons, the arbitrator erred in concluding that Quad’s Versailles facility withdrew from the Fund in 2011 rather than 2010.

B. Issue 2: The 2011 Complete Withdrawal Assessment

Following the arbitrator’s interim decision that Quad’s Versailles facility withdrew in 2011 rather than 2010, the Fund requested that the arbitrator adjudicate the date of withdrawal for all of Quad’s other facilities. The Fund argued that the arbitrator’s decision created a new “rule” that would change the dates of withdrawal at Quad’s other facilities, which in turn would significantly affect Quad’s total withdrawal liability. The arbitrator declined to do so because (1) the Fund had previously stipulated that Quad’s other facilities (except the Memphis facility) withdrew in 2011, and (2) it was too late in the proceedings to raise new issues. Thus, the arbitrator ordered the Fund to rescind the 2010 partial withdrawal assessment and submit a revised 2011 complete withdrawal assessment. The Fund now argues that the arbitrator erred in declining to adjudicate the withdrawal date of Quad’s other facilities.

Because the Court vacates the arbitrator’s decision that the Versailles, facility withdrew in 2010, this issue is now moot. As such, the Court expresses no opinion on (1) whether the Court’s analysis regarding the contribution obligation applies to the other CBAs under which Quad was bound, or (2) whether the arbitrator properly declined to consider those issues based on the Fund’s failure to timely preserve them for adjudication.

C. Issue 3: Application of the Partial Withdrawal Credit

In assessing Quad’s 2011 complete withdrawal liability, the Fund applied two adjustments: the partial withdrawal credit, 29 U.S.C. § 1386 (b)(1), and the 20-year payment cap, 29 U.S.C. § 1399 (c)(1)(B). Under the partial withdrawal credit, the Fund offset Quad’s 2011 complete withdrawal liability by the amount assessed for the, 2009 Memphis partial withdrawal. See 29 C.F.R. § 4206.1 (a) (“The purpose of the credit is to protect a "withdrawing employer from being charged twice for the same unfunded vested benefits of the plan.”). Under the 20-year payment cap, the Fund limited Quad’s 2011 withdrawal liability to the first 20 years of'amortized payments. The Fund applied the partial withdrawal credit before applying the 20-year payment cap; Quad argues that the Fund should have applied the 20-year payment cap before the partial withdrawal credit. The arbitrator concluded that the Fund applied the credit and the payment cap in the correct sequence. For the reasons discussed below, the Court affirms the arbitrator’s holding.

*562 1. Relevant Statutes

Quad’s argument implicates the interaction between three sections of the MPPAA: 29 U.S.C. §§ 1381 , 1386, and 1399.

i. 29 U.S.C. § 1381

Under § 1381(a), “[i]f an employer withdraws from a multiemployer plan in a complete withdrawal or a partial withdrawal, then the employer is liable to the plan in the amount determined under [ 29 U.S.C. §§ 1381-1405 ].” 29 U.S.C. § 1381 (a). Subsection (b)(1), in turn, lays out a roadmap for determining an employer’s withdrawal liability (whether partial or complete):

29 U.S.C. § 1381 (b) (emphasis added). While subsections (b)(1)(B) and (b)(1)(C) are the most directly relevant portions of this statute, the overall structure of this entire section is also relevant.

ii. 29 U.S.C. § 1386

' This statute concerns withdrawal liability calculations in the event, of a partial withdrawal. The two relevant subsections under this statute are subsections (a) and (b)(1). Subsection (a) provides a formula for determining “[t]he amount of an employer’s liability for a partial withdrawal, before the application of sections 1399(c)(1) and 1405 of this title.” 29 U.S.C. § 1386 (a). Subsection (b)(1), which is the partial withdrawal credit, reads as follows:

29 U.S.C. § 1386 (b)(1).

iii. 29 U.S.C. § 1399

Finally, this statute concerns the 20-year payment cap on withdrawal liability. The relevant language reads as follows:

29 U.S.C. § 1399 (c)(1).

2. Analysis

i. Statutory Analysis

The Court agrees with the arbitrator’s conclusion that the partial withdrawal 'credit is applied before the 20-year pay *563 ment cap. Section 1381’s calculation, sequence makes clear that this is the appropriate order. There is no dispute that the adjustments under § 1381(b)(1)(B) come before the 20-year payment cap adjustment under § 1381(b)(1)(C); thus, the question becomes whether the partial withdrawal credit falls under subsection (b)(1)(B). That subsection requires,, “in the case of a partial withdrawal,” that, the Fund adjust the employer’s liability “in accordance with section 1386 of this title.” Here, even though the Fund was calculating Quad’s 2010 complete withdrawal, the entire matter was nevertheless, a “case of partial withdrawal” because Quad partially withdrew from the Fund in 2009. In other words, the word “case” refers not just to the particular assessment being calculated (as Quad contends), but more broadly to any situation where a withdrawal assessment is affected by the existence of a partial withdrawal. Thus, under § 1381(b)(1)(B), the Court must apply all adjustments found in § 1386. There are two adjustments found in § 1386: the formula for determining partial withdrawal liability under subsection (a), and the partial withdrawal credit in subsection (b). Because the Fund was calculating Quad’s 2011 complete withdrawal, subsection (a) was inapplicable. However, because the Fund assessed liability for a partial withdrawal in 2009, Quad was entitled to the partial withdrawal credit from subsection (b). As a result, the Fund correctly applied this credit under § 1381(b)(1)(B) before applying the 20-year payment cap under § 1381(b)(1)(C).

Quad argues that the partial withdrawal credit does not fall under § 1381(b)(1)(B) bécause this does not concern a “case” of partial withdrawal—rather, it concerns a “case” of complete withdrawal to which one applies the partial withdrawal credit. The Court finds this unconvincing for multiple reasons. First, the partial withdrawal credit applies to withdrawal liability assessed in subsequent years regardless whether the withdrawal in those subsequent years is partial or complete. § 1386(b)(1). Under Quad’s reasoning, however, § 1381(b)(1)(B) would refer to the partial withdrawal credit if the subsequent years were a partial withdrawal— but not if they were complete withdrawals. This makes no sense. Quad gives no reason why the sequence in which the partial withdrawal credit is,applied should differ based on whether the withdrawal in the subsequent year is partial or complete.

-Second, § 1381(b)(1)(B) broadly refers to adjustments to be made “in accordance with section 1386 of this title”; thus, by its very terms, it is not limited to adjustments only under certain subsections of § 1386. If Congress intended such a limitation, it could clearly have provided for such. Indeed, the very next subsection of the same statute (i.e., § 1381(b)(1)(C)) specifically identifies the particular subsection of the statute to which it is referring (i.e., § 1399(c)(1)(B)), thus making clear that Congress’ failure to do so under § 1381(b)(1)(B) was not simply an oversight. See Russello v. United States, 464 U.S. 16, 23 , 104 S.Ct. 296 , 78 L.Ed.2d 17 (1983) (“[Wjhere Congress includes particular language in one section of a statute but omits it in another section of the same Act, it is generally presumed that Congress acts intentionally and purposely in the disparate inclusion or exclusion.” (citations .and internal quotation marks omitted)). Alternatively, Congress could have placed the partial withdrawal credit in another section of the statute entirely, which again would have made clear that § 1381(b)(1)(B) does not refer to the partial withdrawal credit.

Third, the congruity in the language between § 1381(b)(1)(B) and § 1386(b)(1) convinces the Court that Congress affirmatively intended for the former to refer to the latter. Section 1381(b)(1)(B) applies “in *564 the case of a partial withdrawal.” Section 1386(b)(1), in turn, states that the partial withdrawal credit applies “[i]n the case of an employer that has withdrawal liability for a partial withdrawal from a plan." This similarity in language substantially undermines Quad’s argument that the phrase “case of partial withdrawal” in § 1381(b)(1)(B) refers only to the specific withdrawal assessment being calculated rather than to any situation where a partial withdrawal may impact the assessment being calculated.

Fourth, § 1381(b)(1) quite clearly lays out an all-inclusive sequence of adjustments to apply in determining withdrawal liability. In fact, an argument could be made that § 1381(b)(1) is not just a road-map for calculating withdrawal liability, but actually defines “withdrawal liability” for the purposes of that part of the MPPAA. § 1381(b)(1) (“The withdrawal liability of an employer to a plan is the amount determined under section 1391 adjusted [fjirst ... next ... then .., finally....” (emphasis added)). Quad’s argument that the partial withdrawal credit is applied outside this sequence of calculations cannot be reconciled with the all-encompassing nature of § 1381(b)(1). Indeed,' § 1381(b)(1)(D) describes the “first" and “final []” adjustments to be made to the § 1391 amount, yet those adjustments would clearly not be the “first” and “final[]” adjustments if—as Quad contends— there is yet a further adjustment to be made to account for the partial withdrawal credit.

Finally, the language of § 1399 also makes clear that the payment cap is applied only after the partial withdrawal credit is applied. Under § 1399(c)(1)(B), withdrawal liability is capped where the “amortization period described in subpara-graph (A) exceeds 20 years.” Subpara-graph (A), in turn, requires the amortiza^ tion of withdrawal liability that has been calculated under “section 1391 of this title, adjusted if appropriate first under section 1389 of this title and then under section 1386.” (This sequence mirrors portions of the sequence set out in § 1381(b)(1).) And, again, there is nothing in subparagraph (A) that limits the adjustments to be made under § 1386. Thus, the withdrawal liability calculation in subparagraph (A) must include any partial withdrawal credit. And because the 20-year payment cap applies only to the withdrawal liability calculated under subparagraph (A), the Cap necessarily comes after the credit.

ii. PBGC Opinion Letter

Quad argues that the Court should defer to an opinion letter written by the Pension. Benefit Guaranty Corporation (PBGC) that .concluded that the 20-year payment cap should be applied before the partial withdrawal credit. In that letter, the PBGC opined as follows:

(AR at-626-27.) 8

The PBGC is “the féderal agency responsible for interpreting • ERISA,” *565 Penn Cent. Corp., 75 F.3d at 534 , and thus the Court owes deference to the PBGC’s interpretation of ERISA and MPPAA if required under Chevron and Skidmore. See, e.g., Pension Ben. Guar. Corp. v. LTV Corp., 496 U.S. 633, 648 , 110 S.Ct. 2668 , 110 L.Ed.2d 579 (1990); Mead Corp. v. Tilley, 490 U.S. 714, 722 , 109 S.Ct. 2156 , 104 L.Ed.2d 796 (1989); Beck v. PACE Int’l Union, 551 U.S. 96, 104 , 127 S.Ct. 2310 , 168 L.Ed.2d 1 (2007). Under Chevron, the Court applies a two-part test to determine whether to defer to an agency’s construction of a statute. “First, applying the ordinary tools of statutory construct tion, the court must determine ‘whether Congress has directly spoken to the precise question at issue. If the intent of Congress is clear, that is the end of the matter; for the court, as well as the agency, must give effect to the unambiguously expressed intent of Congress.’” City of Arlington, Tex. v. F.C.C., 569 U.S. 290 , 133 S.Ct. 1863, 1868 , 185 L.Ed.2d 941 (2013) (citations omitted). “But ‘if the statute is silent or ambiguous with respect to the specific issue, the question for the court is whether the agency’s answer is based on a permissible construction of the statute.’ ” Id. (citations omitted).

“Where Chevron is inapplicable, reasonable agency interpretations may still carry ‘at least some added persuasive force.’” Price v. Stevedoring Servs. of Am., Inc., 697 F.3d 820, 826 (9th Cir. 2012) (en banc) (quoting Metro. Stevedore Co. v. Rambo, 521 U.S. 121, 136 , 117 S.Ct. 1953 , 138 L.Ed.2d 327 (1997)). Under Skidmore, “an agency’s interpretation may merit some deference whatever its form, given the ‘specialized experience and broader investigations and information’ available' to the agency, and given the value of uniformity in its administrative and judicial understandings of what' a national law requires.” United States v. Mead Corp., 533 U.S. 218, 234 , 121 S.Ct. 2164 , 150 L.Ed.2d 292 (2001) (quoting Skidmore v. Swift & Co., 323 U.S. 134 , 65 S.Ct. 161 , 89 L.Ed. 124 (1944)). “Under this level of review, [the court] look[s] to the process the agency used, to arrive at its decision. Among the factors [the court] consider^] are the interpretation’s thoroughness, rational validity, consistency with, prior and subsequent pronouncements, the logic and expertness of an agency decision, the care used in reaching the decision, .as well as the formality of the process used.” Tablada v. Thomas, 533 F.3d 800, 806 (9th Cir. 2008) (citations, internal quotation marks, and brackets omitted).

The Court concludes that the PBGC’s opinion does not warrant Chevron-style deference for two reasons. First, agency opinion letters do not warrant Chevron deference. See, e.g., Christensen v. Harris Cty., 529 U.S. 576, 587 , 120 S.Ct. 1655 , 146 L.Ed.2d 621 (2000) (“Interpretations such as those in opinion letters ... do not warrant Chevron-style deference.”); CenTra, Inc. v. Cent. States, Se. And Sw. Areas Pension Fund, 578 F.3d 592, 601 (7th Cir. 2009) (holding that PBGC opinion letters are not entitled to Chevron deference but may be entitled to Skidmore deference). 9 Second, the Court in any event *566 concludes that there is no ambiguity under the MPPAA as to whether the 20-year payment cap should be applied before the partial withdrawal credit. While the phrase “in the case of a partial withdrawal,” § 1381(b)(1)(B), could have been more clearly worded, the remaining language and structure of this and other sections of the MPPAA concerning the calculation of withdrawal liability leaves no doubt that the partial withdrawal credit comes before the 20-year payment cap. The PBGC’s contrary conclusion cannot supersede unambiguous statutory language. City of Arlington, 133 S.Ct. at 1868 . Finally, the Court concludes that the opinion letter carries little or no added persuasive force under Skidmore . The PBGC’s opinion does not address the myriad arguments that cut strongly against its interpretation, and the PBGC does not appear to rely on any specialized knowledge or expertise in reaching -its conclusion. Rather, the agency appears simply to interpret (in a very curt fashion) the plain language of the statute— something that an Article III court is at least as well equipped to do as the PBGC. For these reasons, the PBGC’s opinion letter does not warrant a different outcome.

D. Issue 4: Attorneys’ Fees and Costs

Quad argues that the arbitrator erred in concluding that the Fund did not act in bad faith during the arbitration process. Specifically, Quad argues that the Fund improperly attempted to submit revised assessments that it knew was contrary to the arbitrator’s findings and orders. Quad also argues that the Fund unnecessarily multiplied the proceedings by seeking a further evidentiary hearing on the sequencing of adjustments, even though it had no new relevant evidence to present.

In an arbitration concerning withdrawal liability under ERISA, “[t]he arbitrator may require a party that initiates or contests an arbitration in bad faith or engages in dilatory, harassing, or other improper conduct during the course of the arbitration to pay reasonable attorneys’ fees of other parties.” 29 C.F.R. § 4221.10 (c). As previously noted, the decision whether to award discretionary attorneys’ fees is reviewed for abuse of discretion. See Van Gerwen v. Guar. Mut. Life Co., 214 F.3d 1041 , 1045 (9th Cir. 2000); McCabe v. Arave, 827 F.2d 634, 640 (9th Cir. 1987); Loveridge, 567 Fed.Appx. at 662 (applying abuse of discretion standard to the question whether or not a party acted in bad faith within the meaning of § 4221.10(c)). The Ninth Circuit has held that the failure to explain the basis of a fee award constitutes an abuse of discretion. See Stanger v. China Elec. Motor, Inc., 812 F.3d 734, 737 (9th Cir. 2016); McCown v. City of Fontana, 565 F.3d 1097, 1102 (9th Cir. 2009) (the district court “must explain how it arrived at its determination with sufficient specificity to permit an appellate court to determine whether the district court abused its discretion in the way the analysis was undertaken”); Chalmers v. City of Los Angeles, 796 F.2d 1205, 1213 (9th Cir. 1986).

While the arbitrator’s decision here did not concern the method for calculating an amount of attorneys’ fees, the Court nonetheless concludes that the question whether a party acted in bad faith for the purposes of awarding attorneys’ fees involve the same kind of fact-intensive inquiries that are best suited for determination by the arbitrator in the first instance. See Trs. of Utah Carpenters’ & Cement Masons’ Pension Trust v. Loveridge, No. 2:10-CV-00809-DS, 2012 WL 2522596 , at *8 (D. Utah June 28, 2012) (“When an arbitrator engages in fact-intensive inquiry, such as deciding whether a party has engaged in improper conduct, the Court refrains overturning findings except for clear error, as the arbitrator ‘is by far best-situated to assess these myriad [facts] and determine *567 whether’ such an event occurred.” (citations omitted)); Dague v. City of Burlington, 976 F.2d 801, 804 (2d Cir. 1991) (“[W]hen questions are presented such as the amount of recovery, the extent to which a plaintiff is a prevailing party, and what if any adjustment is to be given for delay in payment, determination of a reasonable attorney’s fee under the fee-shifting statutes should normally be decided by the district court in the first instance.... We allocate this task to the district court because it is ‘intimately familiar with the nuances of the case, and is in a far better position to make certain decisions than is an appellate court.’ An appellate panel is simply not equipped to give proper consideration to the many-faceted factual disputes that may affect a claim for attorney’s fees. The types of evidence presented on an application such as the one in this ease can normally be best reviewed and analyzed by a district court judge.” (citations and internal quotation marks omitted)). Moreover, it is impossible for this Court to meaningfully review the arbitrator’s decision without any explanation as .to how he arrived at that decision. McCown, 565 F.3d at 1102 ; see Montour v. Hartford Life & Acc. Ins. Co., 588 F.3d 623, 637 (9th Cir. 2009) (“[Fjailure to explain [its conclusion] is yet another factor to consider in reviewing the administrator’s decision for abuse of discretion.”). The Court therefore concludes that the arbitrator abused his discretion by failing to explain why the Fund’s conduct was not improper and did not constitute bad faith. Id.; Stanger, 812 F.3d at 737 . On remand, the arbitrator should provide such an explanation to permit adequate review by this Court.

E. Issue 5: Unclean Hands

Finally, Quad asks this Court to affirm the arbitrator’s order denying the Fund’s request to a delay issuing the final arbitration award based on Quad’s “unclean hands.” The Fund does not respond to this argument, and thus concedes it. See, e.g., Scognamillo v. Credit Suisse First Boston LLC, No. C03-2061 TEH, 2005 WL 2045807 , at *7 (N.D. Cal. Aug. 25, 2005), aff'd, 254 Fed.Appx. 669 (9th Cir. 2007). The Court therefore affirms the arbitrator’s ruling in this respect.

VI. CONCLUSION

For the reasons discussed above, the Court concludes as follows:

(1) The Court VACATES the arbitrator’s decision that Quad’s Versailles facility withdrew from the Fund in 2011;

(2) The Court DISMISSES AS MOOT the Fund’s challenge to the arbitrator’s decision that the Fund assess only a 2011 complete withdrawal;

(3) The Court AFFIRMS the arbitrator’s decision that the Fund correctly applied that the partial withdrawal credit before the 20-year payment cap;

(4) The Court VACATES the arbitrator’s decision that Quad was not entitled to an award of attorneys’ fees and costs under 29 C.F.R. § 4221.10 (c); and

(5) The Court AFFIRMS the arbitrator’s decision not to delay issuance of the final arbitration award based on Quad’s “unclean hands.”

(6) Except as to the issues on which the Court has affirmed the arbitration award, the Court REMANDS the case to the arbitrator for proceedings not inconsistent with this opinion.

The Court further ORDERS the parties to submit a joint proposed judgment to the Court no later than May 1, 2017. If the parties are unable to agree on the form of a judgment, they each may submit a proposed judgment. In that event, objections to the other party’s judgment shall be filed *568 no later than May 4, 2017, and shall not exceed five pages.

IT IS SO ORDERED.

. While there are other situations in which an employer partially or completely withdraws from a pension plan, see 29 U.S.C. §§ 1383 , 1385, they are not relevant to this dispute.

. An assistant administrator at the Fund originally concluded that none of Quad’s facilities withdrew in 2010. (AR at 13, ¶40.) Concerned that not assessing liability for a 2010 partial withdrawal would lead to a substantial loss of revenue, a Fund actuary instructed the administrator to And that at least one - of Quad’s facilities withdrew in 2010 rather thán 2011. (Id. at 13-14, ¶¶41, 44.) The administrator obliged, finding that Quad’s Versailles facility withdrew in 2Ó10. (Id. at 14, ¶’45.) While this might suggest impure motives on the part of the Fund, neither the arbitrator nor Quad made any argument that these communications. have any effect on the date of Quad’s actual withdrawal.

. The arbitrator declined to adjudicate the third issue. (AR at 5.) The parties do not challenge that decision here.

. It is unclear why both parties assume that the CBA becomes void upon NLRB confirmation of the decertification vote rather than when the decertification vote itself occurs; West Coast Sheet Metal appears to hold that the agreement is void upon the decertification vote, and never even mentions NLRB confirmation of the vote. 954 F.2d at 1509-10 . Nevertheless, because the difference would not affect the outcome here (both the decerti-fication vote and NLRB confirmation occurred in December 2010), the Court declines to definitively resolve the issue.

. The Third Circuit has also noted in dicta the potential for a decertification defense. Agathos v. Starlite Motel, 977 F.2d 1500, 1505 (3d Cir. 1992). The Seventh Circuit, on the other hand, has held that decertification does not void a CBA, reasoning that the lack of majority support for a union (which is the basis of a decertification defense) is generally not a defense to a contribution action. See Cent. States, Se. & Sw. Areas Pension Fund v. Schilli Corp., 420 F.3d 663, 671 (7th Cir. 2005). Curiously, the Ninth Circuit has similarly held that lack of majority support for a union is not a defense to a contribution action, yet retains the rule that decertification cuts off the obligation to contribute to a pension plan under a CBA. MacKillop, 58 F.3d at 1444.

, The Court also notes that the period, in which one must use their vacation time (as opposed to the right to the vacation time itself) is not a right that accrued or vested during the lifetime of the CBA, and Quad does not appear to argue to the contrary.

. The arbitrator’s conclusion to the contrary is based solely on the written terms of the Versailles CBA. Because the interpretation of unambiguous plan terms is a legal question, the arbitrator’s conclusion not entitled to any deference. Nw. Adm'rs, 813 F.2d at 225.

. PBGC staff reached the same conclusion in March 2016 during an informal question-and-answer session-' with representatives of the Enrolled Actuaries Program Committee. See *565 Questions to the PBGC and Summary of Their Responses at 33, http://www.pbgc.gov/ documents/2016bluebook.pdf (last visited Apr, 16, 2017). However, the PBGC cautioned that Üiose conclusions “are merely the current views of the individúale PBGC staff members] and do not represent the positions of the Pension Benefit Guaranty Corporation or of any other governmental agency and cannot be relied upon by any person for any purpose.” Id. at 2.

. To the extent'the Ninth Circuit's pre-Chris-tensen cases hold otherwise, see, e.g., Penn Cent. Corp., 75 F.3d at 534 ; H.C. Elliott, Inc. v. Carpenters Pension Trust Fund for N. Cal., 859 F.2d 808, 813 (9th Cir. 1988), they are no longer good law.
