    Raymund A. Paredes, Ph.D.                              Opinion No. GA-0655
    Commissioner of Higher Education
    Texas Higher Education Coordinating Board              Re: Whether the Higher Education Coordinating
    Post Office Box 12788                                  Board's standard method of calculating high
    Austin, Texas 78711                                    school grade point averages must be followed by
    independent school districts (RQ-0716-GA)
    Dear Commissioner Paredes:
    Texas Education Code section 51.807 requires the Texas Higher Education Coordinating
    Board (the "THECB") to adopt rules establishing a "standard method for computing a student's high
    school grade point average" and requires that such method be applied to compute the "grade point
    average of a student applying as a first-time freshman for admission to a general academic teaching
    institution beginning with admissions for the 2009 fall semester." TEX. EDUC. CODE ANN.
    § 51.807(a), (c) (Vernon Supp. 2008). Section 28.0252(a) of the Texas Education Code similarly
    allows the Commissioner of Education (the "Commissioner") to develop a standard method of
    computing a student's high school grade point average; however, to the extent that the
    Commissioner's method conflicts with the THECB' s method, the THECB' s method shall be used
    for purposes ofdetermining admission under subchapter U, chapter 51 ofthe Texas Education Code.
    See ide § 28.0252. As paraphrased, you ask: (1) whether school districts must use the standard
    method adopted by the THECB to calculate grade point averages if the Commissioner has not
    developed a standard method for doing so; (2) whether the THECB is required, or if not required
    then permitted, to provide for a transition period to implement the standard method; (3) whether a
    method that did not allow for a transition period would be unconstitutional; and (4) whether
    subsections 28.0252(b) and (b-1) can be interpreted to mean that the THECB's method applies only
    to students who enter grade nine in the 2007-2008 school year or thereafter. l
    I.      Background
    To place sections 28.0252 and 51.807 in context, we first review the statutory schemes in
    which they are found. In 1997, the Legislature enacted subchapter U, chapter 51 of the Education
    ILetter from Raymond A. Paredes, Ph.D., Commissioner of Higher Education, Texas Higher Education
    Coordinating Board, to Honorable Greg Abbott, Attorney General of Texas, at 1-2 (May 9, 2008) (on file with the
    Opinion Committee, also available at http://www.texasattorneygeneral.gov) [hereinafter Request Letter].
    Raymund A. Paredes, Ph.D. - Page 2                     (GA-0655)
    Code, creating a uniform admission policy for all general academic teaching institutions. 2 See Act
    of May 28, 1997, 75th Leg., R.S., ch. 155, § 1, 1997 Tex. Gen. Laws 304, 304-06 (codified at TEX.
    EDUC. CODE ANN. §§ 51.801-.809 (Vernon 2006 & Supp. 2008)). In relevant part, the Legislature
    enacted what is commonly referred to as the "top ten percent rule," requiring each general academic
    teaching institution to admit an ~pplicantfor admission to the institution as an undergraduate student
    if, among other requirements, the applicant graduated with a grade point average in the top ten
    percent ofthe student's high school graduating class. See TEX. EDUC. CODE ANN. § 51.803 (Vernon
    Supp. 2008). The Legislature also required the governing board of each general academic teaching
    institution to determine whether to adopt an admissions policy that would require admission for a
    student who graduated with a grade point average in the top twenty-five percent of the applicant's
    high school graduating class. See ide § 51.804.
    After the original enactment of subchapter U, chapter 51, the Legislature became aware that
    school districts vary widely in the methods they use to calculate grade point averages and in the
    weight they give to specific classes. See HOUSE COMM. ON HIGHER EDUC., BILL ANALYSIS, Tex.
    H.B. 3851, 80th Leg., R.S. (2007). "The grade point scales used in Texas high schools can vary
    from 3.0 to 12.0-there is no standardization." 
    Id. For instance,
    some school districts give more
    weight to honors and advanced-placement classes, while others do not. Debate on Tex. H.B. 3851
    on the Floor of the House, 80th Leg., R.S. (May 8, 2007) (Statement of Rep. Morrison) (tape
    available from House Video/Audio Servs.).
    In an effort to standardize the method for calculating grade point averages across the state,
    in 2005 the Legislature authorized, but did not require, the Commissioner to develop a standard
    method of computing a student's high school grade point average. See Act of May 27, 2005',
    79th Leg~, R.S., ch. 293, § 1,2005 Tex. Gen. Laws 883, 883 (codified at TEX. EDUC. CODE ANN.
    § 28.0252 (Vernon Supp. 2008)). Under section 28.0252, if the Commissioner adopts a standard
    method, school districts are required to. use the Commissioner's method to comput~ grade point
    averages of students entering grade nine during or after the 2007-2008 school year. 
    Id. Based on
    a review of the rules promulgated by the Texas Education Agency, it appears that, to date, the
    Commissioner has neither proposed nor adopted a standard method that school districts are required
    to use in calculating grade point averages.
    2"'General academic teaching institution' means The University of Texas at Austin; The University of Texas
    at El Paso; The University of Texas of the Permian Basin; The University of Texas at Dallas; The University of Texas
    at San Antonio; Texas A&M University, Main University; The University of Texas at Arlington; Tarleton State
    University; Prairie View A&M University; Texas Maritime Academy; Texas Tech University; University ofNorth Texas;
    Lamar University; Lamar State College-Orange; Lamar State College-Port Arthur; Texas A&M University-Kingsville;
    Texas A&M University-Corpus Christi; Texas Woman's University; Texas Southern University; Midwestern State
    University; University of Houston; University of Texas-Pan American; The University of Texas at Brownsville; Texas
    A&M University-Commerce; Sam Houston State University; Texas State University-San Marcos; West Texas A&M
    University; Stephen F. Austin State University; SuI Ross State University; Angelo State University; The University of
    Texas at Tyler; and any other college, university, or institution so classified as provided in this chapter or created and
    so classified, expressly or impliedly, by law." TEX. EDUC. CODE ANN. § 61.003(3) (Vernon Supp. 2008).
    Raymund A. Paredes, Ph.D. - Page 3                    (GA-0655)
    Subsequently, in 2007, the Legislature required that the THECB establish by rule a standard
    method for computing a student's high school grade point average to be used in relation to a student
    applying for admission to a general academic teaching institution. See Act of May 27, 2007, 80th
    Leg., R.S., ch. 1369, § 2, 2007 Tex. Gen. Laws 4667, 4667-68 (codified as an amendment to
    Education Code section 51.807).3 In doing so, the Legislature maintained the Commissioner's
    authority to develop a standard method for general purposes that, ifadopted, must be used by school
    districts. See ide § 1, at 4667 (codified as an amendment to Education Code section 28.0252(b).
    Section 28.0252, however, was amended to provide that if the Commissioner's standard method
    conflicts with the THECB' s standard method for admissions, the student's grade point average must
    be computed in accordance with the method established by the THECB to determine the student's
    eligibility for admission under subchapter U, chapter 51. 
    Id. ("[T]o the
    extent of a conflict between
    [the Commissioner's] method and the method adopted under Section 51.807, the student's grade
    point average computed in accordance with the method established under Section 51.807 shall
    be used in determining the student's eligibility for;university admission under Subchapter U,
    Chapter 51.").
    Based on statements in your letter, it appears that the THECB is currently developing a
    standard method for admissions but has not formally proposed or adopted a method at this time. See
    Request Letter, supra note 1, at 6. The scope of this opinion is therefore limited to a discussion of
    the statute authorizing the THECB's rulemaking authority. We do not address any additional
    questions or complexities that may be raised by a specific rule once adopted or implemented.
    II.     Analysis
    A.     Whether school districts are required to use the THECB's standard method for
    admissions
    You first ask whether a standard method adopted by the THECB pursuant to section 51.807
    applies to school districts if the Commissioner has not adopted a standard method under section
    28.0252. See Request Letter, supra note 1, at 1.4 We presume that by using the word "apply" you
    mean to ask whether school districts are required to use the THECB standard method to compute
    grade point averages for purposes of admission under subchapter U, chapter 51.
    Section 51.807 states, in relevant P':lrt, that "[t]o ensure a uniform standard for admissions
    under this subchapter, the Texas Higher Education Coordinating Board shall adopt rules establishing
    3Under the Act, the THECB was required to "adopt rules as required by Section 51.807, Education Code, as
    amended by this Act, as soon as practicable after the effective date of[the] Act." Act ofMay 27,2007, 80th Leg., R.S.,
    ch. 1369, §5, 2007 Tex. Gen. Laws 4667, 4668 (emphasis added).
    4The Texas Association ofSchool Administrators ("TASA") has argued that "[i]fthe commissioner ofeducation
    does not adopt a method, a conflict does not exist and thus school districts are not required to use the method adopted
    under Section 51.807 for university admissions." Letter from David Thompson, Counsel for TASA, to Nancy Fuller,
    Chair, Opinion Committee, Office of Attorney General, at 3 (July 18, 2008) (on file with the Opinion Committee).
    Raymund A. Paredes, Ph.D. - Page 4                     (GA-0655)
    a standard method for computing a student's high school grade point average." TEX. EDUC. CODE
    ANN. § 51.807(a) (Vernon Supp. 2008).5 The statute also mandates that the standard method
    established by the THECB "applies to computing the grade point average of a student applying as
    a first-time freshman for admission to a general academic teaching institution beginning with
    admissions for the 2009 fall semester." 
    Id. § 51.807(c).
    On its face, section 51.807 does not expressly state that school districts are required to use
    the THECB standard method to calculate grade point averages. See ide § 51.807. The statute
    requires that the THECB adopt a standard method for calculating a grade point average, and that
    method must be used to calculate the grade point average for purposes of admission under
    subchapter U, chapter 51. See ide However, within section 51.807, the Legislature did not expressly
    state whether school districts must use the THECB' s standard method to compute a student's grade
    point average for purposes of admission under subchapter U, chapter 51. See ide
    Given the silence in the statute as to who is charged with computing the grade point average
    according to the THECB's standard method, we analyze section 51.807 in light of its express
    obje~tive, the legislative intent, and the context in which the statute was passed to determine whether
    section 51.807 implicitly requires school districts to calculate a student's grade point average under
    the, THECB' s standard method for purposes of admission under subchapter U, chapter 51.
    When interpreting a statutory provision, our primary rule is to give effect to the legislative
    intent. City of Houston v. Jackson, 
    192 S.W.3d 764
    , 770 (Tex. 2006); Crown Life Ins. Co. v.
    Casteel, 
    22 S.W.3d 378
    , 383 (Tex. 2000). In the statute itself, the Legislature expressly states that
    the objective ofthe statute is "to ensure a uniform standard for admissions." TEX. EDUC. CODE ANN.
    § 51.807(a) (Vernon Supp. 2008). To achieve that objective, the Legislature mandated that the
    THECB's standard method be applied to students applying for college admission for the 2009 fall
    semester. 
    Id. § 51.807(c).
    Although the Legislature did not expressly state in section 51.807 that
    school districts are required to use the THECB~s standard method for admissions, the uniformity
    intended by the Legislature will not be achieved if school districts may continue using their diverse,
    individual methods to determine students' grade point averages for purposes of admission under
    subchapter U, chapter 51 rather than a standard method. Due to the nature ofthe uniform admission
    policies in sections 51.803 and 51.804, the school districts are the only entities with all of the
    information necessary to determine class rank because they are the only entities that possess grades
    for all their students. To determine which students fall within the top ten or twenty-five percent, the
    school districts will have to rank the senior class by grade point averages computed according to the
    THECB's standard method for admissions.
    5To avoid confusion, we point out that the Legislature adopted two separate acts that included sections amending
    section 51.807 of the Education Code. The fIrst section 51.807 addresses the THECB' s general rulemaking authority
    relating to the operation of admissions programs, and it is not addressed herein. See TEX. EDUC. CODE ANN. § 51.807
    (Vernon Supp. 2008) (as added by Act of May 27,2007, 80th Leg., R.S., ch. 941, § 4, 2007 Tex. Gen. Laws 3256,
    3258). For purposes of this opinion, only the se,c,ond section 51.807, addressing the THECB' s authority to create rules
    establishing a standard method for calculating grade point averages, is applicable. See 
    id. (as added
    by Act of May 27,
    2007, 80th Leg., R.S., ch. 1369, § 2,2007 Tex. Gen. Laws 4667, 4667-68).
    Raymund A. Paredes, Ph.D. - Page 5             (GA-0655)
    The legislative history also supports the conclusion that school districts must use the standard
    method adopted by the THECB for purposes ofadmission under subchapter U, chapter 51. See TEX.
    GOV'T CODE ANN. § 311.023 (Vernon 2005) (stating that in construing a statute, legislative history
    may be considered). Representative Morrison, the author ofHouse Bill 3851 which enacted section
    51.807, explained that the intent ofthe bill was to create uniformity and standardization for purposes
    of admissions and financial aid eligibility:
    [W]henever a student is applying for admissions and financial aid
    eligibility, [the bill] would allow the coordinating board to come up
    with a methodology for standardizing high school GPAs for all
    institutions of higher learning so that whenever a student is applying
    they're on a more level playing field, because each school district
    does it differently.
    Debate on Tex. H.B. 3851 on the Floor of the House, 80th Leg., R.S. (May 8, 2007) (statement of
    Rep. Morrison) (tape available from House Video/Audio Servs.). Additionally, the fiscal note on
    House Bill 3851 assumes that school districts are required to utilize the THECB' s standard method,
    stating:
    Given the complexity and variety of methods of calculating high
    school grade point average, it is assumed that school districts would
    likely incur some cost in conforming to an adopted methodology.
    Anticipated costs would include modification oflocal procedures and
    software.
    Fiscal Note, Tex. H.B. 3851, 80th Leg., R.S. (2007) (enrolled version) (emphasis added).
    By enacting section 51.807, the Legislature.intended that all students applying for admission
    to a general academic teaching institution have their grade point averages and corresponding class
    ranks computed in a uniform way for purposes of admission to those institutions. The Legislature's
    objective can be attained only if school districts calculate grade point averages for purposes of
    admission by using a standard method. Ifthe Commissioner adopts a method and the THECB agrees
    to use the same method for admissions, that method can be used to calculate grade point averages
    for purposes of admission and all other purposes. If the Commissioner chooses not to adopt a
    standard method or implements a method that conflicts with the THECB' s method, school districts
    will be required to use the THECB's method for admissions in order to achieve the Legislature's
    intent.
    When the Legislature enacted section 51.807, it also enacted an amendment to section
    28.0252(b) that supports this construction. See Act of May 27, 2007, 80th Leg., R.S., ch. 1369,
    §§ 1-2, 2007 Tex. Gen. Laws 4667, 4667-68. In interpreting a statutory provision, "we must always
    consider the statute as a whole rather than its isolated provisions." Helena Chern. Co. v. Wilkins,
    47 S.W.3d 486,493 (Tex. 2001). "We should not give one provision a meaning out of harmony or
    inconsistent with other provisions, although it might be susceptible to such a construction standing
    alone." 
    Id. As discussed
    above, section 28.0252, originally enacted in 2005, authorizes the
    Raymund A. Paredes, Ph.D. - Page 6            (GA-0655)
    Commissioner to create a standard method for calculating grade point averages, which, if adopted,
    must be used by school districts. See TEX. EDUC. CODE ANN. § 28.0252 (Vernon Supp. 2008). In
    2007, in the same bill that enacted section 51.807, the Legislature amended section 28.0252. See Act
    of May 27, 2007, 80th Leg., R.S., ch. 1369, § 1 2007 Tex. Gen. Laws 4667, 4667. The amendment
    provides that to the extent of a conflict between the Commissioner's standard method and the
    THECB's standard method, school districts must use the THECB' s standard method "in determining
    [a] student's eligibility for university admission under Subchapter U, Chapter 51." 
    Id. If the
    Legislature had not intended for school districts to use the THECB' s method, this amendment would
    have been unnecessary. Thus, while preserving the Commissioner's authority, section 28.0252 as
    amended evinces the legislative intent that the THECB' s method be used to calculate grade point
    averages for purposes of admission under subchapter U, chapter 51.
    You tell us that certain "public education stakeholders" interpret section 28.0252(b) to mean
    that "[i]fthe Commissioner does not develop a method under Section 28.0252 ..., 'a conflict does
    not exist and thus school districts are not required to use the method adopted under Section 51.807
    for university admissions.'" Request Letter, supra note 1, at 6. This interpretation ignores the
    express language of section 51.807 and the context in which the statute is found. Even in the
    absence of a standard method from the Commissioner under section 28.0252, school districts are
    required by virtue of section, 51.807 to use the standard method for admissions established by the
    THECB.
    Important to note is that the Legislature intended that the THECB' s method be used for
    purposes of admission under subchapter U, chapter 51, leaving open the possibility that school
    districts may, as authorized bylaw, continue to use other methods to calculate grade point averages
    for other purposes. See TEX. EDUC. CODE ANN. § 51. 807 (Vernon Supp. 2008). Ifthe Commissioner
    adopts a standard method, the school districts are required to use that method except to the extent
    that it conflicts with the THECB' s standard method for calculating grade point averages for purposes
    of admission under subchapter U, chapter 51. See 
    id. §§ 28.0252(b),
    51.807. However, in the
    absence ofa standard method from the Commissioner, nothing in the statute prevents school districts
    from continuing to use their individual methods for calculating grade point averages for all other
    purposes, such as high school graduation rank. The THECB' s method is required only for purposes
    of admission under subchapter U, chapter 51.
    B.   Whether a transition period is required or permitted for implementation of the
    THECB's standard method
    You next ask whether the THECB is required, or if not required, then permitted to provide
    a transition period for implementation of its standard method "so as not to adversely affect students
    currently in high school who did not have notice of the method or a reasonable opportunity to plan
    their high school academic choices based on the method?" Request Letter, supra note 1, at 1. This
    same concern was raised in a House Committee on Higher Education meeting by one of the
    Committee's members:
    My thought is just to make sure that ... the students know how the
    computations are going to be made. And let me tell you why I make
    Raymund A. Paredes, Ph.D. - Page 7             (GA-0655)
    this comment. My nephew, who is graduating in May, was
    valedictorian for three and half years and last week was told he was
    not.... He told me what happened was, senior year, he asked his
    counselor, "what do I take? ..." [And his high school counselor] told
    him, "take criminal justice." Some other kids took anatomy. [The
    school] computed criminal justice at three points and anatomy at four
    points.
    Hearings on Tex. HB. 3851 Before the House Comm. on Higher Educ., 80th Leg., R.S. (Apr. 16,
    2007) (statement of Rep. Alonzo) (emphasis added) (tape available from House Video/Audio
    Servs.). The Committee member's statements suggest that he interpreted the standard method to be
    used on a prospective basis only, and no comments were made to the contrary. You similarly note
    that many students throughout Texas high schools have been making course curriculum decisions
    in an effort to maximize their potential grade point average and that the standard method, if applied
    retroactively, "will affect thousands of students who currently are in their junior year ofhigh school
    and who will be entering their senior year of school by the time the method is in effect." Request
    Letter, supra note 1, at 7.
    The statute itself is silent as to whether the THECB' s standard method is to· be applied
    retroactively or whether any transition period is allowed so that students have notice of what the
    THECB's standard method is before it applies to them. See TEX. EDUC. CODE ANN. § 51.807
    (Vernon Supp. 2008). The only direction the Legislature provided is that the method adopted must
    be used beginning with admissions for the 2009 fall semester:
    The standard method established under Subsection (a) for computing
    a student's high school grade point average applies to computing the
    grade point average of a student applying as a first-time freshman for
    admission to a general academic teaching institution beginning with
    admissions for the 2009 fall semester. This subsection expires
    January 1, 2010.
    
    Id. § 51.807(c).
    If this subsection requires the THECB' s standard method to be used to calculate the grade
    point average for years preceding the creation ofthe THECB' s standard method, the method would
    be implemented retroactively. The Code Construction Act provides that a "statute is presumed
    to be prospective in its operation unless expressly made retrospective." TEX. GOV'T CODE ANN.
    § 311.022 (Vernon 2005); See Nat 'I Carloading Corp. v. Phoenix-El Paso Express, 
    176 S.W.2d 564
    ,
    568 (Tex. 1943). The same general principles apply for agency rules. See R.R. Comm 'n v. Lone Star
    Gas Co., 656 S.W.2d421, 425 (Tex. 1983);AII Saints HealthSys. v. Tex. Worker's Compo Comm 'n,
    
    125 S.W.3d 96
    , 104 (Tex. App.-Austin 2003, pet. denied) ("Agency rules and rates are set for the
    future, and not for the past."). In the absence of any special indication or reason, a statute will not
    be applied retroactively, even when there is no constitutional impediment against it. Coastal Indus.
    Water Auth. v. Trinity Portland Cement Div., 
    563 S.W.2d 916
    , 918 (Tex. 1978); see also State v.
    Raymund A. Paredes, Ph.D. - Page 8             (GA-0655)
    Humble Oil & Refining Co., 169 S.W.2d 707,708-09 (Tex. 1943) ("[S]tatutes will not be applied
    retrospectively unless it appears by fair implication from the language used that it was the intention
    of the Legislature to make it applicable to both past and future transactions.").
    By the same principle, a statutory grant oflegislative rulemaking authority generally will not
    be understood to encompass the power to promulgate retroactive rules unless that power is conveyed
    in express terms. See Bowen v. Georgetown Univ. Hosp., 
    488 U.S. 204
    , 208 (1988); see also R.R.
    Comm 'n v. Lone Star. Gas Co., 
    656 S.W.2d 421
    , 425 (Tex. 1983); All Saints Health Sys. v. Tex.
    Workers' Compo Comm'n, 
    125 S.W.3d 96
    ,104 (Tex. App.-Austin 2003, pet. denied) ("Agency
    rules and rates are set for the future, not for the past."). All doubts as to retroactivity are resolved
    against retroactive operation of a statute. Ex Parte Abell, 
    613 S.W.2d 255
    , 258 (Tex. 1981).
    Section 51.807 does not suggest an intention by the Legislature to make the statute, or the
    rules that it authorizes the THECB to implement, retroactive. See TEX. EDUC. CODE ANN. § 51.807
    (Vernon Supp. 2008). The statute does not expressly state that the THECB's standard method be
    applied to calculate a student's grade point average for grades earned before the calculation method
    is adopted. See id.; see also TEX. GOV'T CODE ANN. § 311.022 (Vernon 2005) (statute is presumed
    prospective unless expressly made retrospective). The statute simply provides that the method
    adopted by the THECB should be used beginning with admissions for the 2009 fall semester.
    The general language used by the Legislature makes it possible to implement the THECB' s
    method on a prospective basis only. Simply because the THECB's method must be used beginning
    with admissions for the 2009 fall semester does not mean that it must be implemented retroactively.
    In enacting section 51.807, the Legislature gave the THECB broad discretion and rulemaking
    authority in operating admissions programs: "[t]he board may adopt other rules relating to the
    operation of admissions programs ...." TEX. EDUC. CODE ANN. § 51.807(b) (Vernon Supp. 2008).
    Based on this authority, we conclude that the THECB is authorized to implement the standard
    method in a manner that is consistent with section 51.807' s objective but that nevertheless complies
    with the presumption against retroactive application. Furthermore, given the authority to implement
    the statute prospectively and the presumption against retroactivity, we conclude that the THECB is
    required to implement its standard method on a prospective basis only and has the latitude to provide
    for a transition period.
    Because we conclude that section 51.807 should not be applied retroactively, we need not
    address your question regarding whether it would be a violation of the Texas Constitution, article
    I, section 16 if the Board adopted a standard method and applied it to students currently in high
    school. See Request Letter, supra note 1, at 2. Because we determine that the statute and
    accompanying rules were only meant to apply prospectively, we do not reach this issue. See In re
    MC.C., 187 S.W.3d 383,385 (Tex. 2006) (refusing to reach the issue of whether a constitutional
    right was impai~ed after determining that statute only applied prospectively).

    SUMMARY
    Section 51.807 ofthe Texas Education Code provides that the
    Texas Higher Education Coordinating Board (the "THECB") shall
    adopt rules establishing a standard method for computing a student's
    high school grade point average, and such method must be used to
    calculate the grade point average of a student applying as a first-time
    freshman for admission to a general academic teaching institution
    beginning with admission for the 2009 fall semester. Section 28.0252
    authorizes the Commissioner of Education to adopt a standard
    method to compute a student's high school grade point average
    and requires school districts to use that method, unless it conflicts
    with the THECB' s method. The standard method established by the
    THECB must be used to calculate a student's grade point average for
    purposes of determining eligibility for university admission under
    subchapter U, chapter 51, regardless of whether the Commissioner
    has developed a standard method as permitted under section
    28.0252(a) of the Texas Education Code.
    Because section 51.807 does not suggest an intention by
    the Legislature to make the THECB' s standard method apply
    retroactively, and because there is a presumption against retroactive
    application of both statutes and agency rules, the THECB's standard
    method should be applied on a prospective basis only.
