Analysis of Proposed Xarelto Settlement Discount Rates – Debunking Defendants Rationale



Analysis of Proposed Xarelto Settlement Discount Rates

Debunking Defendants Rationale

 This is a follow up to the Mass Tort Nexus article “Xarelto Settlement: Dead on Arrival” – link: Xarelto-Settlement-Dead-on-Arrival? April 15, 2019


(MASS TORT NEXUS MEDIA) This article is intended to address the Xarelto defendants’ contentions that certain settlement offer “discounts” are justified for client cases arising in 2015 and 2016 due to changes in the FDA label,  which the defendant contends brought warnings contained in the label into adequacy. This paper will also address defendant’s contention that cases arising under the laws of the States of Texas and Michigan merit a massive discount in settlement value (offers).

We will focus on the Xarelto label change from 11/07/2018, AND an additional label change was made on 01/15/2019 related to Eosinophilia, which could be relevant to many of the Xarelto cases already filed as well as give rise to a Xarelto Litigation II, that could involve more injured individuals than the current Xarelto Litigation. The relevance and significance of the 01/15/2019 “Eosinophilia” label change will be addressed by Mass Tort Nexus in the near future.

Mass Tort Nexus has also received information that there is an ongoing investigation related to Xarelto potentially causing kidney injury, which may or not be related to Eosinophilia. We will continue to provide more information related to this subject in future articles. Given the new Eosinophilia warning and the investigation related to Kidney injury, and the 11/07/2018 label change related to anticoagulation tests (and the possible impact on future Xarelto case trials) Mass Tort Nexus understands why the defendants might be eager to reach a settlement sooner rather than later. Conversely, there is no reason why plaintiffs’ firms should believe the defendants to be in a superior negotiating position, nor be willing to accept subpar settlements for their existing cases.

It is worth nothing that the 11/07/2018 label change (admission) by the defendant that the most commonly used anticoagulation tests are “not recommended” (in reality likely have no diagnostic value) would make it far more difficult for the defendants to prevail in future trials under the Learned Intermediary Doctrine, as doctors would be less likely to testify that, “they would still do everything exactly as they did when originally prescribing Xarelto.” Had the defendant revealed the foregoing before the prior bellwether trials, the outcome of those trials may have been very different.  It is not surprising that the defendants are eager to settled Xarelto cases without having to face another trial post the 11/07/2018 and 01/15/2019 label changes.

Had the defendants revealed the information related to the most common anticoagulation tests used as “not being recommended” prior to the bellwether trials, doctors testifying in support of a defendants “Learned Intermediary Defense” would likely face questions like these:

 Plaintiffs’ Counsel:  So, Dr. Smith, I see that you performed an INR test to make sure that my client was correctly anticoagulated, that their blood was not to thick or too thin, is that right?

Dr. Smith: Yes

Plaintiffs’ Counsel:  Were you aware that as of 11/07/2018 the defendants recommend that this test not be used and in fact, the literature shows that this test provides no diagnostic value when a person is taking Xarelto?

Dr. Smith: It unlikely that Dr. Smith will say he knew the above when he prescribed Xarelto as he would essentially be admitting to medical malpractice.

Plaintiffs’ Counsel:  So, Dr. Smith, would you still today, follow the same protocol when prescribing Xarelto and use an INR test to make sure the dose of Xarelto did not have the patient’s blood to thick (likely to clot) or too thin (likely to bleed).

Dr. Smith: Unlikely that Dr. Smith would say he would still do what the defendant now recommends he not do.

Plaintiffs’ Counsel:  Dr. Smith, just out of curiosity, do you think the words “No Routine Blood Testing Needed” mean the same thing as “The blood test routinely used don’t work”?

The same line of questioning could be used for doctors that treated a Xarelto bleed or clot.

The contention that any label change could render a product adequately warned for all circumstances and facts relevant to every possible client injury scenario is somewhat preposterous; however, we will address and rebut the defendant’s contentions more directly. Although the Xarelto warning label has been changed numerous times since 2016, we only need to review the label change made on 11/07/2018 (see below) to conclude that the label was not adequate in any clients case in which the referenced anticoagulation tests were used in the “dosing” of Xarelto or the treatment of any Xarelto related injury 11/07/2018.

 11/07/2018 Xarelto Label Change

 5.0 Warnings and Precautions

 5.2 Risk of Bleeding

Reversal of Anticoagulant Effect

Additions and/or revisions underlined:

… anticoagulant activity of rivaroxaban. Use of procoagulant reversal agents, such as prothrombin complex concentrate (PCC), activated prothrombin complex concentrate or recombinant factor VIIa, may be considered but has not been evaluated in clinical efficacy and safety studies. Monitoring for the anticoagulation effect of rivaroxaban using a clotting test (PT, INR or aPTT) or anti-factor Xa (FXa) activity is not recommended.

Mass Tort Nexus Comment: The highlighted language above was added to the Xarelto FDA (U.S) 0n 11/07/2018, indicating that the use of PT, INR, aPTT anti-factor Xa (FXa) is not recommended. A more accurate statement (warning) would be that these tests have no diagnostic value and should not be used when evaluating dosing for individual patients nor treating bleeds and other conditions related to Xarelto, while the patient has Xarelto in their system.

 We will first address the 11/07/2018 label change as it related to the defendants contentions that the Xarelto label “adequately warned”  of the risks associated with label changes made in 2015 and 2016 as well as the justification (or lack thereof) for any discounts to base settlement offers arising therefrom.

Mass Tort Nexus opinion is as follows:

  1. At minimum, no discount is justified in any case arising before 11/07/2018, in which any of the anticoagulation tests now “not recommended” for use, where used by the prescribing physician immediately before and or any time after prescribing Xarelto, for use by the specific client. The doctor nor the patient were adequately warned with regard to these tests providing any diagnostic value that could serve to mitigate the risks associated with the use of Xarelto.  Additionally, for any client that presented at a medical facility (prior to 11/07/2018), with a Xarelto related injury which resulted in the use of the tests in the process of treating that injury, the warning label was not sufficient to mitigate the risks associated with the use of tests which the defendant now recommends not be used.
  2.  Today the warning label remains inadequate and no discount based on a contention that the warning label was brought into adequacy at any point in the past, is warranted. Until the defendants make further changes to the label including, but not limited to, giving the “anticoagulation” test “warning” greater prominence on the label as well as changing the “not recommended” portion of the statement to reflect a more truthful representation, that is less likely to be overlooked or misunderstood by prescribing physicians. An adequate warning would include information as to why the tests are not recommended (they likely have no diagnostic value).
  3.  It would be difficult for the defendants to argue that the fact that the most commonly used anticoagulation tests “are not recommended” for use in dosing Xarelto or treating a Xarelto injury, would not likely have impacted some doctors decision to prescribe the drug had they been previously warned prior to 11/07/2018. In reality, given the lack of prominence of the 11/07/2018 label change and the fact that no additional educational efforts are being made by defendants (that we are aware of), to insure that doctors are now aware that these tests are “not recommended” and in fact, likely have no diagnostic value, it is probable that the 11/07/2018 warning has not significantly decreased the risk posed Xarelto users, related to this new “warning.

 Before addressing Texas 82.007 and Michigan 600.2946, it is important to point out that one of the most Signiant claims made by the makers of Xarelto, in their effort to establish their product as being superior to Warfarin was that “no routine blood testing (anticoagulation tests) was needed” for patients using Xarelto. Patients taking Warfarin and other VKA’s (Vitamin K Antagonists) do require routine monitoring to insure their anticoagulation levels remain in a therapeutic range.

The “No Routine Blood Testing Needed” claim of the makers of Xarelto, made to the FDA and the public appears to have been very misleading. Mass Tort Nexus has yet to determine how the makers of Xarelto concluded that No Routine Blood Testing was needed for patients taking Xarelto. The 101,743 adverse event reports filed with the FDA related to Xarelto since 2011, is one indicator that “Routine Blood Testing” is needed to insure Xarelto user’s safety. If no Routine Blood Testing was needed, then why have Xarelto patients experienced such a high volume of bleeding and clotting events? The FDA warning letter sent to the makers of Xarelto (provided at the end of this document), is highly relevant to this topic.

If Xarelto was so well designed that a doctor could just assume that patients would be maintained with a therapeutic range (not too thin and likely to bleed or too thick and likely to clot), then why has the FDA received Xarelto 101,753 adverse event reports since 2011, many involving bleeding or clotting that might have been prevented with “routine testing’?


Texas and Michigan Cases

To the best of our knowledge, the defendant has yet to raise a defense under Texas 82.007 and Michigan 600.2946 in any case, much less prevail in arguments arising under these laws.

Neither Texas 82.007 nor Michigan 600.294 provide an absolute defense for drug manufacturers. Both state’s laws have language which provide a plaintiff with means, by which to overcome the presumption that these laws provide immunity for a given defendant. We will refer to the language in both States laws as the “savings clause” in the remainder of this article. We will also address each law separately with regard to the burden plaintiffs would face, in overcoming a defense raised under either Texas 82.007 or Michigan 600.294.

First, We Will review the “savings clause” for both Texas 82.007 and Michigan 600.2946 available to plaintiffs to overcome the presumption of drug manufacturer immunity arising under the two laws. See the relevant savings clauses and links to the entire statutes below:

Texas   82.007

(2)(b)  The claimant may rebut the presumption in Subsection (a) as to each defendant by establishing that:

(1)  the defendant, before or after pre-market approval or licensing of the product, withheld from or misrepresented to the United States Food and Drug Administration required information that was material and relevant to the performance of the product and was causally related to the claimant’s injury;

(3)(A) the defendant recommended, promoted, or advertised the pharmaceutical product for an indication not approved by the United States Food and Drug Administration;

(B)  the product was used as recommended, promoted, or advertised;  

Michigan 600.2946

(5) In a product liability action against a manufacturer or seller, a product that is a drug is not defective or unreasonably dangerous, and the manufacturer or seller is not liable, if the drug was approved for safety and efficacy by the United States food and drug administration, and the drug and its labeling were in compliance with the United States food and drug administration’s approval at the time the drug left the control of the manufacturer or seller. However, this subsection does not apply to a drug that is sold in the United States after the effective date of an order of the United States food and drug administration to remove the drug from the market or to withdraw its approval. This subsection does not apply if the defendant at any time before the event that allegedly caused the injury does any of the following:

(a) Intentionally withholds from or misrepresents to the United States food and drug administration information concerning the drug that is required to be submitted under the federal food, drug, and cosmetic act, chapter 675, 52 Stat. 1040, 21 U.S.C. 301 to 321, 331 to 343-2, 344 to 346a, 347, 348 to 353, 355 to 360, 360b to 376, and 378 to 395, and the drug would not have been approved, or the United States food and drug administration would have withdrawn approval for the drug if the information were accurately submitted

As a preliminary point, if any discount was justified arising under Texas 82.007or Michigan 600.2946, it should be minimal in light of the fact that the defendant has neither raised a defense in any individual case (to the best of our knowledge), nor prevailed in such a defense. A small discount might be warranted to allow plaintiffs to avoid the cost of litigating any matter raised by defense in the unlikely event that the defendants are willing to incur the cost of litigating the matter themselves.

Secondly, if any discount arising under Texas 82.007 and Michigan 600.2946 was justified, cases arising under Texas 82.007 would warrant a less significant discount than those arising under Michigan 600.2946, for reasons we will address below.

It is worth noting that the defendants must affirmatively raise a defense under Texas 82.007 or Michigan 600.2946 and doing so may expose their clinical trials, communications with the FDA, (including warning letters related to their advertising, one of which we have included at the end of this document), to discovery and scrutiny they may wish to avoid. Mass Tort Nexus would be interested in any internal communications, as well as third party communications the defendants engaged in related to the death of Arnold Palmer (including communications with his family) as we have long held the opinion that Xarelto may have caused or contributed to the death of Xarelto’s most famous spokesperson.

Comment: Texas 82.007, does not require a showing that any information that may have been withheld or misrepresentation made to the FDA was “intentional.” Texas 82.007 does not require a plaintiff to plead nor show that the FDA would, and the drug would not have been approved, or the United States Food and Drug Administration would have withdrawn approval for the drug if the information were accurately submitted. Michigan 600.2946, does require plaintiffs to show and plead that any misrepresentations or withholding of information and the drug would not have been approved, or the United States food and drug administration would have withdrawn approval for the drug if the information were accurately submitted.

Michigan 600.2946 obviously places a far more significant burden on a plaintiff seeking to rebut the presumption of immunity than does Texas 82.007. Pleading that a drug would not have been approved, or the United States food and drug administration would have withdrawn approval for the drug if the information were accurately submitted, can be problematic in light of the SCOTUS decision Buckman v. Plaintiff Legal Committee:

The foregoing should not be interpreted as presenting an impossible burden for plaintiffs to overcome under Michigan 600.2946 as was shown in the Second Circuit decision in DESIANO v. WARNER-LAMBERT & CO. Also see TAYLOR v. SMITHKLINE BEECHAM Michigan Supreme Court decision These two well-reasoned rulings and opinions make it clear that 1. Plaintiffs can meet the requirements set forth in Michigan 600.2946 to overcome the presumption of immunity without running afoul of Buckman. 2. Plaintiffs can prevail in overcoming a defense raised under Michigan 600.2946 as they did in DESIANO.

Notwithstanding the foregoing, the burden placed un plaintiffs under Michigan 600.2946 is still far greater than that placed on plaintiffs by Texas 82.007.  It appears that any defendant has a better chance of prevailing in raising a defense under Michigan 600.2946 than one raised under Texas 82.007 however, given the fact that Michigan has a population of 9,996,000,(3.05% percent of the U.S. population) while Texas has a population of 27,700,000 (8.45% percent of the U.S. population), would the defendants be willing to undertake the time and expense (and continued concern from the market) involved in raising a defense under Michigan 600.2946, which would not dispose of a significant number of cases, if they prevail given that there is no reason to believe that a disproportionate number of the total Xarelto cases on file arise under Michigan law. Additionally, would the defendant be likely to undertake the time and expense (and continued concern from the market) involved in raising a defense under Texas 82.007, with a far less likelihood of prevailing than in Michigan.

The plaintiff’s burden with overcoming a defense raised under Texas  82.007 is obviously less arduous that than the burden over overcoming a defense raised under Michigan 600.2946. Due to the foregoing, the defendant’s application of the same discount (if any is justified) to cases arising under Texas law to those arising under Michigan Law, is not justified.


Michigan and Texas Law and the 11/07/2018 Label Change

Texas 82.007 and Michigan 600.2946:

Texas 82.007: The defendants’ statements in the 11/07/2018 label change “not recommending” these tests are still arguably misleading given that the test apparently have no diagnostic value when a patient is taking Xarelto and more importantly represent important information previously withheld from the FDA and/or mispresenting to the FDA. A strict interpretation of C would not require a plaintiff to show that that the actions or inactions of the defendant were intentional. Arguably, the 11/07/2018 label change related to these tests could be rebut the presumption that the protection provided from Texas 82.007 is available to the defendant.

Michigan 600.2946: The same reasoning applied to the analysis of Texas  82.007 applies to Michigan 600.2946 in this matter with one exception, Michigan 600.2946 requires a showing that the defendants actions or inactions were intentional and a showing that the FDA would not have approved or would have withdrawn the approval for the product if not for the information withheld or misrepresentations made. MTN provides an analysis below aimed at showing what the defendants knew and when they knew it relevant to the warnings they neglected to add to their label until 11/07/2018.


The following analysis is more relevant to Michigan 600.2946 than to Texas 82.007. There is a high degree of confidence that Plaintiffs would prevail in any defense raised under Texas 82.007.

In that overcoming a defense raised under Michigan 600.2946 requires a showing that the defendant intentionally made misrepresentations the FDA or intentionally withheld information from the FDA. Additionally, under Michigan 600.2946   plaintiffs must make a colorable argument that the FDA would not have approved the drug or would have later withdrawn approval, absent the misrepresentations or withheld information. The 11/07/2018 FDA label change related to anticoagulant testing would be an example of evidence plaintiffs might present to meet the requirements of Michigan 600.2946. In that Michigan’s law require plaintiffs show the offending actions or inactions of the defendant were intentional, demonstrating what the defendants knew (relevant to the referenced anticoagulation tests) and when they knew it would be important in overcoming a defense raised under Michigan 600.2946.

It should be noted that a defense raised under Michigan 600.2946 or Texas 82.007 exposes the defendant to broad discovery, through which plaintiffs would likely discover far more evidence to support their rebuttal arguments than can be discovered in the public domain.  For our instant purpose however, we will focus on determining when the defendant knew or should have known that the anticoagulation tests listed in the 11/07/2018 label change provide no diagnostic value for patients on Xarelto.

Mass Tort Nexus has conducted a review of the publicly available literature in order to establish what the defendant knew or should have know and when, related to anticoagulation testing with commonly used modalities and methods. We will not present a chronological listing (not exhaustive) of information in the public domain relevant to this topic.

 It should be noted that any information or data published in clinical literature must be developed over time (before it is reported). We can safely assume that any information reported in the medical literature in 2012 was known to the defendant at the time they sought the initial FDA approval for Xarelto, granted in July of 2011. If the defendants were to raise a defense under Michigan 600.2946 or Texas 82.007, plaintiffs would likely be allowed broad discovery which would reveal that the defendants possessed or should have possessed the information related to anticoagulation tests that they withheld from the FDA and prescribing physicians until 11/07/2018.

 No Exhaustive Review of the Literature


The data below was taken from a presentation from Ohio Society of Pharmacist Association in 2012. Given the fact that the information below was reliant on clinical observations prior to the presentation of the below, it is likely that the defendant was aware of the issue related to INR testing, prior to seeking U.S. FDA approval (granted July 1, 2011)

• Dabigatran
– aPTT
• Appears to be a useful measure in hemorrhagic emergency
• Therapeutic ranges have not yet been established
– Ecarin clotting time
• Also useful in hemorrhagic emergency, but not widely available.
• Rivaroxaban and Apixaban
– Prothrombin time, but not INR
• Appears to be useful in hemorrhagic emergency
• Therapeutic ranges have not yet been established
– HepTest, PiCT, and chromagenic assay all appear to be
useful, but not commonly available

 May 2012

Rivaroxaban: Quantification by anti-FXa assay and influence on coagulation tests: a study in 9 Swiss laboratories.

RXA plasma levels can be quantified accurately and precisely by a chromogenic anti-FXa assay on different coagulometers in different laboratories. Ingestion of 10mg RXA results in significant alterations of both PT- and aPTT-based coagulation assays.

July 2012 Rivaroxaban: A practical Guide

INR testing should be preformed just before the next intake of Rivaroxaban on the INR measurement

Thrombosis Journal 2013

Because rivaroxaban and other target-specific oral anticoagulants have different mechanisms of action from traditional anticoagulant agents, laboratory tests used for these traditional agents (such as PT/international normalized ratio [INR] or activated partial thromboplastin time) are not suitable for target-specific oral anticoagulants

Pub Med   May 2017

Direct factor Xa inhibitors such as rivaroxaban or apixaban may prolong prothrombin time (PT) and elevate international normalized ratio (INR). However, these tests are not reliable for assessing the anticoagulation effects of these agents such as rivaroxaban or apixaban may prolong prothrombin time (PT) and elevate international normalized ratio (INR). However, these tests are not reliable for assessing the anticoagulation effects of these agents.

See the warning letter sent from the FDA to the makers of Xarelto. Mass Tort Nexus believes more warning letters like this one exist and will continue our efforts to discover all relevant FDA communications. This warning letter is highly relevant to the prior subject matter of this article.

NDA 202439 XARELTO (rivaroxaban) tablets   

June 6, 2013

RE: NDA #202439

XARELTO (rivaroxaban) tablets

MA #215

Dear Ms. McGregor-Beck:

The Office of Prescription Drug Promotion (OPDP) of the U.S. Food and Drug Administration (FDA) has reviewed a direct-to-consumer (DTC) print advertisement (K02XS121040 AF) (Print Ad) for XARELTO (rivaroxaban) tablets (Xarelto) submitted by Johnson & Johnson International, Inc. (Johnson & Johnson) on behalf of Janssen Pharmaceuticals, Inc. under cover of Form FDA 2253 and observed during routine surveillance in the January/February 2013 issue of WebMD magazine. The Print Ad is false or misleading because it minimizes the risks associated with Xarelto and makes a misleading claim. Thus, the Print Ad misbrands Xarelto in violation of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. 352(n) and FDA implementing regulations. 21 CFR 202.1(e)(5)(i); (e)(7)(viii), (ix).


Below is the indication and summary of the most serious and most common risks associated with the use of Xarelto.1 According to its FDA-approved product labeling (PI), in pertinent part:

Xarelto is indicated to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation.

There are limited data on the relative effectiveness of XARELTO and warfarin in reducing the risk of stroke and systemic embolism when warfarin therapy is well controlled.

 The PI for Xarelto contains Boxed Warnings regarding increased risk of stroke after discontinuation in patients with nonvalvular atrial fibrillation and the risk of spinal/epidural

hematoma. The PI also contains Contraindications regarding active pathological bleeding and severe hypersensitivity reaction to Xarelto, as well as Warnings and Precautions regarding the risk of bleeding, use in patients with renal impairment and hepatic impairment, use with P-gp and strong CYP3A4 inhibitors or inducers, and risk of pregnancy related hemorrhage. The most common adverse reactions with Xarelto were bleeding complications.

Minimization of Risk Information

 Promotional materials are false or misleading if they fail to present risks associated with a drug with a prominence and readability reasonably comparable with the presentation of information relating to the benefits of the drug. Factors impacting prominence and readability include typography, layout, contrast, headlines, paragraphing, white space, and other techniques apt to achieve emphasis. The Print ad prominently presents various efficacy claims for Xarelto, such as, but not limited to, the following, that are presented in large, bolded and/or colorful text and graphics (emphasis original):

• “If you have atrial fibrillation (AFib)”

• “Ready to break your AFib routine?”

• “XARELTO® is the first and only once-a-day prescription blood thinner for patients with AFib not caused by a heart valve problem, that is proven to reduce

the risk of stroke—without routine blood monitoring.”

• “…With XARELTO®, there’s no routine blood monitoring—so you have more time for yourself. There are no dietary restrictions, so you’re free to enjoy the healthy foods you love. And there are no dosage adjustments, which means you can manage your risk with just one pill a day, taken with your evening meal. Learn how XARELTO® can help simplify your AFib-related stroke risk treatment….”

In contrast, the risk information is presented on the preceding adjacent page without any of the emphasis (i.e. color scheme, borders, layout, and graphics) used with the efficacy claims. The result is a presentation which appears unconnected to the efficacy claims and is therefore not likely to draw readers’ attention. This overall presentation misleadingly  minimizes the risks associated with Xarelto because it fails to convey this important risk information with a prominence and readability reasonably comparable to the efficacy claims. We note that the Print Ad contains the statement, “Please see accompanying Medication Guide on the following pages” (emphasis original) at the bottom of the page, and that risk information is presented on an adjacent page, but this is not sufficient to mitigate the overall misleading presentation.

Misleading Claim

 The Print Ad includes the following claim (emphasis original):

• “And there are no dosage adjustments…”

The above claim misleadingly suggests that dosage adjustments are not necessary with Xarelto. However, according to the DOSAGE AND ADMINISTRATION section of the PI, the dose should be lowered to 15 mg once daily for patients with renal impairment who may have a CrCL of 15 to 50 mL/min. In addition, the WARNINGS AND PRECAUTIONS section of the PI states, “…Periodically assess renal function as clinically indicated…and adjust therapy accordingly….” Thus, patients with renal impairment may need to have their dosage adjusted while on Xarelto therapy.

Conclusion and Requested Action

For the reasons discussed above, the Print Ad misbrands Xarelto in violation of the FD&C Act, 21 U.S.C. 352(n) and FDA implementing regulations. 21 CFR 202.1(e)(5)(i); (e)(7)(viii), (ix). OPDP requests that Johnson & Johnson immediately cease the dissemination of violative promotional materials for Xarelto such as those described above. Please submit a written response to this letter on or before June 20, 2013, stating whether you intend to comply with this request, listing all promotional materials (with the 2253 submission date) for Xarelto that contain violations such as those described above, and explaining your plan for discontinuing use of such violative materials.

Please direct your response to the undersigned at the Food and Drug Administration,

Center for Drug Evaluation and Research, Office of Prescription Drug Promotion, 5901-B Ammendale Road, Beltsville, Maryland 20705-1266 or by facsimile at (301) 847-8444. To ensure timely delivery of your submissions, please use the full address above and include a prominent directional notation (e.g. a sticker) to indicate that the submission is intended for OPDP. Please refer to MA# 215 in addition to the NDA number in all future correspondence relating to this particular matter. OPDP reminds you that only written communications are considered official.
