The sole question presented is whether the decision of the BTA was unreasonable or unlawful. R. C. 5717.04. We do not sit either as a “super” Board of Tax Appeals or as a trier of fact de novo. 3535 Salem Corp. v. Lindley (1979), 58 Ohio St. 2d 210, 212.
Youngstown contends that the BTA’s valuation of the subject property was, under the circumstances of this case, unreasonable and unlawful because said valuation was not ascertained by determining true value in terms of the probable selling *401price of the property in an arm’s length transaction between a willing buyer and willing seller. See State, ex rel. Park Investment Co., v. Bd. of Tax Appeals (1964), 175 Ohio St. 410, 412. Appellees and cross-appellants contend that the BTA’s valuation was unlawful and unreasonable because the BTA did not find that the highest and best use of the subject property on the tax lien date was as a steelmaking facility. AppeUees and cross-appellants contend further that the BTA erred in considering events subsequent to the January 1,1977 tax lien date in reaching its valuation. The final issue raised by appellees and cross-appellants is whether the BTA must allocate value according to parcel number.
I.
Cardinal Federal S. & L. Assn. v. Bd. of Revision (1975), 44 Ohio St. 2d 13, paragraphs two, three and four of the syllabus, set forth three basic propositions that are relevant to this cause:
“The Board of Tax Appeals is not required to adopt the valuation fixed by any expert or witness. (Hibschman v. Bd. of Tax Appeals, 142 Ohio St. 47; Benedict v. Bd. of Revision, 170 Ohio St. 62; Shaker Square Co. v. Bd. of Revision, 170 Ohio St. 369, approved and followed.)
“The Board of Tax Appeals is vested with wide discretion in determining the weight to be given to evidence and the credibility of witnesses which come before the board. (American Steel & Wire Co. of New Jersey v. Bd. of Revision, 139 Ohio St. 388; Shaker Square Co. v. Bd. of Revision, 170 Ohio St. 369; Benedict v. Bd. of Revision, 170 Ohio St. 62, approved and followed.)
“The fair market value of property for tax purposes is a question of fact, the determination of which is primarily within the province of the taxing authorities, and this court will not disturb a decision of the Board of Tax Appeals with respect to such valuation unless it affirmatively appears from the record that such decision is unreasonable or unlawful. (Bd. of Revision v. Fodor, 15 Ohio St. 2d 52, approved and followed.)”
Youngstown structures its argument to avoid a direct collision with the Cardinal principles by controverting the precise method used by the BTA to determine value instead of *402directly disputing the end result of the methodology which is, of course, a dollar amount valuation. Youngstown summarizes its position in this manner:
“ * * * [T]he ‘market’ approach is the only appraisal method applicable for determining the fair market value (true value) of the old, outmoded Youngstown plants. No other appraisal technique can possibly indicate the approximate amount of money that a perspective [sic] purchaser would have paid for the plants in 1977. ***[0]nly the American Appraisal [Youngstown’s appraiser] Reports introduced at trial valued all the Youngstown properties by the ‘market approach.’ * * * Since there was no other acceptable evidence of true value whatever before the Board from which it could ascertain fair market value, the Board should have adopted the American Appraisal Valuations.” (Emphasis deleted.)
Even though Youngstown couches its argument in methodological terms, this argument taken to its logical conclusion would require the BTA to adopt the valuation fixed by Youngstown’s experts. Such a requirement would be contrary to the rules expressed in paragraphs two and three of the syllabus in Cardinal, supra. We decline to bind the BTA to a particular method of valuation because the imposition of rigid methodological strictures would necessarily impinge upon the BTA’s wide discretion to weigh evidence and assess the credibility of witnesses.
The BTA did not specifically state whether it based its valuation of the subject property on the “market” or the “cost” approach to valuation; nor was it required to do so. In American Steel & Wire Co. v. Bd. of Revision (1942), 139 Ohio St. 388, this court, at page 391, stated that:
“With respect to these [valuation] methods it should be observed that, while reproduction cost, depreciation, opinions as to market value, and income may be given proper consideration, true value is a question of fact to be determined by the taxing authorities. It does not appear from the record that the Board of Tax Appeals applied any particular method exclusively but merely determined the true value of the buildings on each parcel from all the evidence. This course was in conformity to law.”
The BTA made its true value determination “[a]fter care*403fully considering the entire record,” which is in essence the same standard this court approved in American Steel & Wire Co., supra. This approach is reasonable and lawful; Youngstown’s contentions to the contrary are without merit.
In short, the Board of Tax Appeals is not required to adopt the appraisal methodology espoused by any expert or witness.
II A.
Appellees and cross-appellants’ first and third propositions of law call into question the factual underpinnings of the BTA valuation.5 MCBR contends that “it was the responsibility of the Board of Tax Appeals***to place itself in the center of the Youngstown Sheet & Tube complex as of January 1,1977; to determine the highest and best use of the property as of that date; and to value the property in accord with that highest and best use for tax year 1977.” Flowing from this characterization of the BTA’s responsibility are the further contentions that the BTA erred first in factoring the September 1977 shutdown announcement into its valuational calculus and secondly in confusing the announcement of plant closings with the actual shutdowns of the steelmaking facilities, some of which did not occur until after the end of the tax year at issue.
We reject appellees and cross-appellants’ limited view of the BTA’s responsibility. While the BTA must determine value as of the tax lien date, it must also consider all the circumstances surrounding the property to be valued. The BTA cannot ignore events prior and subsequent to the tax lien date that affect the true value of the subject property on the tax lien date. As this court stated in American Steel & Wire Co. v. Bd. of Revision, supra:
*404“In determining the value of land or the improvements thereon all the facts and circumstances relating to the nature of the property, its availability for the purpose for which it was constructed or for any other purpose for which it may be used, its obsolete character, if such it has, and every other factor that tends to prove the true value in money of the land and the improvements thereon, and evidence of facts occurring after as well as before the tax lien day of the year involved within reasonable limitations are admissible. ” Id. at 392. (Emphasis added.) See, also, R. C. 5715.01 (“in determining true value***all facts and circumstances***shall be used”).
The BTA utilized the following rationale:
“Thus, the Board must consider the reality that the subject property was producing steel on January 1, 1977. However, the Board likewise cannot ignore the fact that steel production was greatly curtailed in September 1977 and thereafter, since the causes for such shutdown were evident on tax lien date.”
Appellees and cross-appellants narrowly focus on the use of the subject property for steelmaking on January 1, 1977, and describe Youngstown as a going concern on that date. Youngstown’s substantial losses in 1975 and 1976 belie the “going concern” description. Notwithstanding the subject property’s continued use for steel production as of the tax lien date, Youngstown was a going-out-of-business concern. The September 1977 shutdown announcement did little more than confirm the inevitable. Under these circumstances BTA acted lawfully and reasonably in considering pre- and post-tax lien date factors that affected the true value of Youngstown’s property on January 1, 1977.
II B.
Appellees and cross-appellants’ second and fourth propositions of law raise issues of appraisal methodology.6 Our discus*405sion in Part I of this opinion is dispositive of these issues; the BTA is not bound to adopt any particular method of valuation to the exclusion of other methods in its determination of true value.
II C.
Appellees and cross-appellants’ final proposition of law deals with a procedural matter. The question is whether the BTA erred in failing to specify true value for each individual parcel of the subject property. The BTA valuations were based on the aggregate values of the three Youngstown plant sites. The three plant sites, however, contain some 14 individual parcels, which are located in three separate taxing districts. As a consequence of the BTA’s aggregate plant site valuations, the Mahoning County Auditor cannot allocate true value on a per parcel basis pursuant to his statutory duty. R. C. 5713.01. Therefore, it is incumbent on the BTA on remand to break down its aggregate plant site valuations into individualized parcel values before certifying its decision and order to the county auditor.
The decision of the Board of Tax Appeals is affirmed as to its valuation of the subject property, but the cause is remanded for an allocation of value on a per parcel basis.
Decision affirmed and cause remanded.

Mahoney, J., of the Ninth Appellate District, sitting for P. Brown, J.Appellees and cross-appellants’ proposition of law No. 1 states:
“The Board of Tax Appeals acted unreasonably and unlawfully in failing to find that the highest and best use of appellants real property as of January 1,1977 was as a steelmaking facility. The Board of Tax Appeals further erred in failing to value appellant’s real property for tax year 1977 in accord with such finding.”
Proposition of law No. 3 states:
“The Board of Tax Appeals erred in reducing the true value of all Youngstown Sheet & Tube’s real property on the basis of a finding that the plant had shutdown in late 1977 when evidence adduced at the board revealed that substantial portions of the steel mill continued to operate well into 1979.”
Appellees and cross-appellants’ proposition of law No. 2 states:
“The appraisals submitted by appellee/cross appellant Mahoning County Board of Revision, constituted the only evidence before the Board of Tax Appeals of true value of the property in issue as those appraisals were founded on assumptions conducive to finding true value as defined in statute and case law.”
Proposition of law No. 4 states:
“The Board of Tax Appeals did not err in declining to adopt the valuation figures *405championed by the Youngstown Sheet & Tube Company because those figures were derived through indulgence of the unfounded assumption that property which was a functioning steel mill complex on January 1, 1977 was not on that date suitable for utilization as a steel producing enterprise.”
