Before the Court at Docket 9 is Defendant Alaska Native Tribal Health Consortium's ("ANTHC") Motion to Dismiss. Plaintiff Elena Barron opposed at Docket 12. ANTHC replied at Docket 13. Oral argument was not requested and was not necessary to the Court's decision.
BACKGROUND
ANTHC is a tribal organization that provides health care services to Alaska Natives, American Indians, and other eligible individuals pursuant to Titles I and V of the Indian Self-Determination and Education Assistance Act, 25 U.S.C. §§ 5321 - 32, 5381 - 99 ; the Alaska Tribal Health Compact; and a Funding Agreement with the Secretary of Health and Human Services.1 Ms. Barron is a respiratory therapist formerly employed by ANTHC.2 Ms. Barron's Complaint alleges as follows:
Ms. Barron began her employment with ANTHC in November 2016.3 Shortly after beginning work, Ms. Barron heard other employees discussing "HR hires" in a manner that "cast HR hires in a negative light."4 Ms. Barron later asked department director Craig Bevercomb if she was considered a "HR hire," and he replied that she was.5 Ms. Barron alleges that over the course of the next several weeks, Ms. Barron's supervisor Zachary Malbalay treated Ms. Barron - who is a Native Alaskan - differently than her Caucasian coworkers.6 Mr. Malbalay required Ms. Barron to conduct a procedure that a Caucasian coworker was not required to conduct; he also excused a Caucasian employer from an assignment in Pediatrics because the coworker was pregnant, and instead gave the assignment to Ms. Barron - who was also pregnant at the time.7
On Friday, December 9, Mr. Malbalay approached Ms. Barron and told her that Mr. Bevercomb had asked him to talk to her. Mr. Malbalay told Ms. Barron that she was in a "unique position" because she *1235was "more likely to have relatives come to [the] hospital because she was Native-Alaskan."8 He then "suggested that because [Ms. Barron] was Native-Alaskan she needed to find other employment with one of the other hospitals in Anchorage."9 Mr. Malbalay told Ms. Barron that she must decide over the weekend to either quit or meet with Mr. Bevercomb, "presumably to be fired."10 On Monday, December 12, Ms. Barron spoke with Mr. Bevercomb, who denied telling Mr. Malbalay to speak with her.11 Mr. Bevercomb acknowledged that Mr. Malbalay should not be asking questions about her race, but stated that it was "within Mr. Malbalay's authority to ask her questions" and that Mr. Malbalay was "just uninformed about Alaskan Native culture."12 Mr. Bevercomb told Ms. Barron that she should continue to work with Mr. Malbalay in spite of the incident, and Ms. Barron initially agreed to do so.13 Later that day, however, Ms. Barron alleges there was a "noticeable change in [Mr.] Malbalay's demeanor towards" Ms. Barron, from which she inferred that Mr. Bevercomb had spoken with Ms. Malbalay about the incident.14 Because of Mr. Malbalay's "cold" and "unfriendly" behavior toward her, Ms. Barron requested that Mr. Malbalay no longer orient her.15
Ms. Barron spent the remainder of her orientation working with other co-workers, who "stated that she was doing an excellent job."16 During the orientation, however, Mr. Malbalay "made comments stating that [Ms. Barron] was not working hard."17 In January 2017, Ms. Barron discovered that her child had died in utero; she was forced to deliver her stillborn child by C-section.18 Mr. Bevercomb "did not provide support in [Ms. Barron's] request for leave" following this incident.19 Ms. Barron was ultimately allowed to take some leave time after she appealed to Mr. Bevercomb's supervisors.20
On February 13, 2017, Mr. Malbalay "showed his animosity toward Alaska Natives and their culture" by "mak[ing] a rude, disgusted, facial expression after a co-worker thanked [Ms. Barron] for a jar of fish that she had given her."21 Ms. Barron contacted ANTHC's Human Resources concerning this incident, but no action was taken.22
Sometime after the February 13 incident, Mr. Malbalay received a promotion.23 Shortly thereafter, Mr. Malbalay wrote an email to hospital administrators "attacking [Ms. Barron] professionally."24 Ms. Barron was required to respond to Mr. Malbalay's allegations.25 On May 4, 2017, Ms. Barron "was required to report to the HR department, *1236and answer questions about her work skills."26 She began to experience medical problems caused by work-related stress.27
"Based on the harassment that she was experiencing at work," Ms. Barron filed with the Anchorage Equal Rights Commission.28 However, ANTHC did not respond to the commission.29 Ms. Barron also contacted ANTHC's Human Resources, but her concerns were not resolved.30 Because ANTHC "would not provide a resolution to [Ms. Barron's] complaints of racial discrimination, she felt she had no option [but] to quit the hostile working environment that had become unbearably stress-filled."31 Ms. Barron's employment ended on August 20, 2017.32
On February 26, 2018, Ms. Barron filed a Complaint in the Superior Court for the State of Alaska, Third Judicial District at Anchorage.33 On May 21, 2018, ANTHC removed the case to this Court pursuant to 28 U.S.C. § 1441.34 Ms. Barron brings a claim against ANTHC for disparate treatment and retaliation on the basis of race in violation of the Civil Rights Act of 1866, 42 U.S.C. § 1981.35
On June 19, 2018, ANTHC filed the instant Motion to Dismiss.36
LEGAL STANDARD
I. Jurisdiction and Applicable Law
The Court has jurisdiction pursuant to 28 U.S.C. § 1331 because this is a civil action with a claim alleged under federal law, 42 U.S.C. § 1981. ANTHC is also a federal contractor and as such the Court has jurisdiction pursuant to 28 U.S.C. § 1442(a).
II. Standard for Dismissal
A defendant may seek dismissal of an action for lack of subject matter jurisdiction under Federal Rule of Civil Procedure 12(b)(1). When such a motion is made, the plaintiff has the burden of proving jurisdiction.37 If the defendant raises a factual challenge to a court's jurisdiction, as opposed to a facial challenge based solely on the allegations in the complaint, a court may consider matters outside the pleadings in ruling on the motion.38 Here, ANTHC submitted additional materials with its motion to dismiss.39 "[N]o presumptive *1237truthfulness attaches to plaintiff's allegations, and the existence of disputed material facts will not preclude the trial court from evaluating for itself the merits of jurisdictional claims."40
The issue of tribal sovereign immunity is "quasi jurisdictional" in the sense that it "may be asserted at any time."41 "Although sovereign immunity is only quasi-jurisdictional in nature, Rule 12(b)(1) is still a proper vehicle for invoking sovereign immunity from suit."42 "In the context of a Rule 12(b)(1) motion to dismiss on the basis of tribal sovereign immunity, 'the party asserting subject matter jurisdiction has the burden of proving its existence,' i.e. that immunity does not bar the suit."43 A court may " 'hear evidence regarding jurisdiction' and 'resolv[e] factual disputes where necessary' " when determining such a motion.44
DISCUSSION
ANTHC advances three arguments in support of its motion to dismiss. First, it contends that 42 U.S.C. § 1981 does not apply to ANTHC. Second, it contends that tribal sovereign immunity protects ANTHC from suit. Third, it contends that Ms. Barron's claims amount to tort claims, which may only be brought pursuant to the Federal Tort Claims Act ("FTCA").45 Given the Court's finding that tribal sovereign immunity applies, the Court does not address the remaining arguments.
1. Tribal sovereign immunity protects ANTHC from suit.
"Indian tribes have long been recognized as possessing the common-law immunity from suit traditionally enjoyed by sovereign powers."46 This tribal immunity extends to tribal governing bodies and to tribal agencies or entities which act as an "arm of the tribe."47 Tribal sovereign immunity may extend to an organization created by more than one tribe.48
ANTHC is a statewide Alaska Native tribal health consortium.49 It was established pursuant to Section 325 of Public Law 105-83 with the purpose of "entering into self-determination and self-governance agreements with the Indian Health Service [ ("IHS") ] to operate and manage health services" for the benefit of Alaska Native tribes.50 It is also a Co-Signer of the Alaska Tribal Health Compact ("ATHC"), which authorizes tribes and tribal health organizations to operate health and health-related *1238programs.51 ANTHC has funding agreements with the IHS, and provides "a wide range of medical health, community health and other services" for Alaska Natives that were formerly provided by the IHS's Alaska Office.52 ANTHC is controlled by a 15-member Board of Directors comprised of Alaska Native representatives.53 Twelve directors are selected by the twelve regional Alaska Native tribal health consortia, which are "comprised of, and controlled by, the federally-recognized Alaska Native tribes from their respective regions."54 One director is appointed by the Metlakatla Indian Community, a federally recognized Alaska Native tribe.55 The final two directors are elected by Alaska Native tribes that are not affiliated with a regional health consortium.56
The Ninth Circuit has considered whether a particular entity constitutes an "arm of a tribe" that is entitled to tribal sovereign immunity on several occasions. In Allen v. Gold Country Casino , the Ninth Circuit considered whether a casino that was owned and operated by the federally recognized Tyme Maidu Tribe was entitled to tribal sovereign immunity.57 The Circuit Court noted that the Casino's creation "was dependent upon [tribal and state] government approval" as required pursuant to the Indian Gaming Regulatory Act ("IGRA").58 It further noted that one of the purposes of IGRA is to ensure "that the Indian tribe is the primary beneficiary of the gaming operation," and that the interstate gaming compact that created the casino provided that it would "enable the Tribe to develop self-sufficiency, promote tribal economic development, and generate jobs and revenues to support the Tribe's government and governmental services and programs."59 In light of "the purposes for which the Tribe founded this Casino and the Tribe's ownership and control of its operations," the Circuit Court concluded that the casino "functions as an arm of the Tribe ... [and] accordingly enjoys the Tribe's immunity from suit."60
In conducting its analysis of sovereign immunity, the Allen court relied in part on Marceau v. Blackfeet Housing Authority.61 In Marceau , the Ninth Circuit considered whether the Blackfeet Housing Authority ("BHA") was entitled to sovereign immunity. The BHA was established by the Blackfeet Tribe as required by Housing and Urban Development ("HUD") regulations.62 The BHA's enabling ordinance charged it with "[a]lleviating the acute shortage of decent, safe and sanitary dwellings for persons of low income" and "[r]emedying unsafe and [u]nsanitary *1239housing conditions that are injurious to the public health, safety and morals."63 HUD granted the BHA authorization and funding that was used to build homes.64 Noting that tribal sovereign immunity "extends to agencies and subdivisions of the tribe," the Circuit Court concluded that "the Blackfeet Tribe's sovereign immunity extends to the Blackfeet Housing Authority."65
More recently, in White v. University of California , the Ninth Circuit identified five factors that courts should consider when determining whether an entity is entitled to tribal sovereign immunity: "(1) the method of creation of the economic entities; (2) their purpose; (3) their structure, ownership, and management, including the amount of control the tribe has over the entities; (4) the tribe's intent with respect to the sharing of its sovereign immunity; and (5) the financial relationship between the tribe and the entities."66 In White , the Circuit Court considered whether the Kumeyaay Cultural Repatriation Committee ("KCRC") constituted an "arm" of the member tribes of the Kumeyaay Nation.67 The KCRC was formed pursuant to resolutions by the twelve Kumeyaay Nation members tribes to address "concerns over the repatriation efforts, or lack thereof, under [the Native American Graves and Repatriation Act ("NAGPRA") ] in San Diego."68 Applying the five factors described above, the Circuit Court concluded that the KCRC was an "arm of the tribe" that was entitled to sovereign immunity:
[T]he Repatriation Committee was created by resolution of each of the Tribes, with its power derived directly from the Tribes' sovereign authority. The Repatriation Committee is comprised solely of tribal members, who act on its behalf. KCRC tribal representatives are appointed by each tribe. The process by which the Repatriation Committee designates the particular tribe to receive remains under NAGPRA is defined and accepted by the Tribes. The Repatriation Committee is funded exclusively by the Tribes. As the district court noted, the whole purpose of the Repatriation Committee, to recover remains and educate the public, is "core to the notion of sovereignty." Indeed, "preservation of tribal cultural autonomy [and] preservation of tribal self-determination," are some of the central policies underlying the doctrine of tribal sovereign immunity. Given these undisputed facts, the district court properly concluded that the Repatriation Committee was an "arm of the tribe" for sovereign immunity purposes ....69
These cases suggest that ANTHC is an arm of Alaska's tribes that is entitled to sovereign immunity. Like the casino examined in Allen , ANTHC's creation was authorized pursuant to a federal law intended to promote tribal self-sufficiency.70 And like the BHA, ANTHC receives federal funding to conduct activities that benefit tribe members. The factors identified in *1240White also indicate that ANTHC is entitled to sovereign immunity. ANTHC was formed by Alaska Native tribes. By "entering into self-determination and self-governance agreements" with the IHS, ANTHC provides and manages health services that benefit members of Alaska Native tribes. The structure of ANTHC's board places control over the ANTHC's ownership and management in representatives of the Alaska Native tribes. Like the KCRC, ANTHC's purpose - entering into "self-determination and self-governance agreements" - is "core to the notion of sovereignty." Finally, ANTHC receives federal funding to carry out governmental functions critical to Alaska Native tribes.
In her opposition, Ms. Barron contends that the Fourth Circuit has rejected the contention "that Alaska Native Corporations have sovereign immunity such as to avoid § 1981 claims."71 The case she cites for this proposition is distinguishable, however. In Aleman v. Chugach Support Services, Inc. , the Fourth Circuit concluded that Chugach Support Services, Inc. ("Chugach") was not entitled to sovereign immunity.72 Unlike ANTHC, the entity examined in Aleman was a for-profit Alaska Native Corporation created pursuant to the Alaska Native Claims Settlement Act ("ANCSA").73 While Alaska Native Corporations are owned and managed by Alaska Natives, they are distinct legal entities from Alaska Native tribes.74 As the Aleman court recognized, the question whether sovereign immunity shields a tribe from liability is distinct from the question whether "ownership of ... corporations by Alaska Natives and their devisees, or any other attribute, entitles [those corporations] to immunity from suits."75 Unlike an Alaska Native Corporation, ANTHC is an entity created and controlled by Alaska Native tribes that promotes tribal self-determination and fulfills governmental functions. Accordingly, it constitutes an arm of the Alaska Native tribes that is entitled to sovereign immunity.
2. ANTHC's tribal sovereign immunity is a bar to § 1981 liability.
Suits against Indian tribes and entities that constitute an "arm of a tribe" are barred by sovereign immunity, "absent a clear waiver ... or congressional abrogation."76 "There is a strong presumption against waiver of tribal sovereign immunity."77 Waiver of sovereign immunity may not be implied and must be expressed unequivocally.78 Similarly, congressional abrogation of sovereign immunity may not *1241be implied and must be "unequivocally expressed" in "explicit legislation."79
Here, Ms. Barron's suit alleges disparate treatment and retaliation on the basis of race in violation of 42 U.S.C. § 1981. There is no indication that ANTHC has waived its immunity for such a claim. Accordingly, the Court must determine whether Congress has abrogated tribal sovereign immunity as to § 1981 claims. While the Ninth Circuit has not addressed this question, other circuits have concluded that tribal sovereign immunity is a bar to § 1981 liability. In Yashenko v. Harrah's NC Casino Co., LLC , the Fourth Circuit concluded without elaboration that the Eastern band of Cherokee Indians enjoyed sovereign immunity from a § 1981 suit.80 In Aleman , the Fourth Circuit reaffirmed that it had "recognized Indian tribal immunity as a bar to Section 1981 liability."81 Similarly, in Taylor v. Alabama Intertribal Council Title IV J.T.P.A. , the Eleventh Circuit concluded that "nothing in § 1981 supports the proposition that Congress intended to abrogate tribes' immunity and permit private parties to bring employment discrimination claims against them for intramural tribal employment decisions."82
Ninth Circuit cases addressing statutory abrogation of tribal sovereign immunity provide additional guidance. In White , the Circuit Court held that NAGPRA did not abrogate tribal sovereign immunity, even though its enforcement clause grants district courts "jurisdiction over any action brought by any person alleging a violation of [NAGPRA]."83 The Circuit Court noted that the clause "does not contain any language expressly abrogating tribal sovereign immunity."84 In reaching this conclusion, the White court relied in part on Santa Clara Pueblo v. Martinez , in which the Supreme Court indicated that a statutory provision conferring on federal courts "jurisdiction of any civil action authorized by law to be commenced by any person" did not abrogate tribal sovereign immunity with respect to a suit to secure enforcement of Title I the Indian Civil Rights Act.85 Similarly, in Miller v. Wright , the Ninth Circuit concluded that tribal immunity was not abrogated by federal antitrust laws that referred to states, foreign nations, and "corporations and associations existing under or authorized by the laws of either the United States, the laws of any of the Territories, the laws of any State, or the laws of any foreign country."86 In contrast, in Krystal v. Navajo Nation , the Ninth Circuit held that the Bankruptcy Code abrogated tribal sovereign immunity with respect to an adversary action under the Code.87 The Circuit Court noted that *124211 U.S.C. § 106(a) expressly abrogated the sovereignty of all "governmental units," and that a separate provision defining "governmental units" established that all "foreign or domestic governments" are considered governmental units for the purpose of the Bankruptcy Code.88
These cases suggest that Congress has not abrogated tribes' sovereign immunity from § 1981 liability. Unlike the Bankruptcy Code, § 1981 does not include language clearly expressing an intent to abrogate the sovereign immunity of all governmental units, including Indian tribes. Rather, the statute's articulation of rights applicable to "[a]ll persons within the jurisdiction of the United States" is similar to the statutory language examined in White and Martinez.89 Therefore, Congress has not "unequivocally expressed" an intent to abrogate tribal sovereign immunity in "explicit legislation." Because ANTHC is entitled to sovereign immunity, and because immunity from § 1981 claims has not been waived by the tribe or abrogated by Congress, ANTHC is immune from suit.
CONCLUSION
In light of the foregoing, IT IS ORDERED that ANTHC's Motion to Dismiss at Docket 9 is GRANTED. The Clerk of Court is directed to enter a final judgment.
