Critical Takeaway: Treat “1993” as Context, Not Proof

When you see a 1993 reference in sourcing, procurement, or product documentation, the safest professional approach is to treat it as contextual background rather than direct evidence of current performance. In practice, buyers should verify how the information was produced, whether it reflects the same product category, and whether supplier documentation remains consistent with current regulatory and quality expectations. This is especially important when “1993” appears alongside supplier terms, pricing cues, or archival descriptions, because procurement decisions require evidence that is traceable, comparable, and relevant to the present.

Historically dated statements can be useful, but they are not the same thing as current proof. A supplier may have been founded in 1993, may have first designed a product in that year, may have issued an early catalog entry then, or may have recorded an early version of a process description. Each of these possibilities can be meaningful in different ways, yet none automatically confirm that the current manufactured product, the current manufacturing process, or the current regulatory posture matches what buyers need today. Procurement is therefore not a confidence game played with vintage dates; it is an evidence-driven process designed to reduce uncertainty across cost, risk, and operational requirements.

Accordingly, the professional posture is to treat 1993 as a prompt: What exactly does it refer to? What has changed since? What evidence exists now that supports the buyer’s required specification and acceptance criteria? When you treat historical dates as questions rather than answers, you prevent avoidable errors such as misaligned specification assumptions, incorrect unit basis comparisons, or reliance on documentation that no longer corresponds to the current configuration.

Why “1993” References Still Matter in Supplier Evaluation

Even though 1993 is not a quality metric by itself, archival or historical mentions often appear in legacy catalog entries, long-running manufacturer documentation, or industry retrospectives used by procurement specialists. Objectively, such references can help teams understand:

• Lineage and continuity—whether a supplier has longstanding product families or process histories.
• Evolution of standards—how requirements likely changed over time (testing methods, labeling norms, or compliance frameworks).
• Documentation maturity—whether record-keeping practices have been consistent enough for buyers to interpret older statements responsibly.

However, a professional buyer should never assume that an older date guarantees current capability. Instead, the date should prompt better questioning: What changed since 1993? What evidence supports the present claim? Are the cited materials still accurate under today’s scope?

To elaborate, it helps to recognize that historical references can appear for several different reasons, and the buyer should not treat them as interchangeable:

• Company origin date: A supplier that has existed since 1993 may have stability, but stability is not equivalent to current compliance or product qualification.
• Product introduction date: If a product line was introduced in 1993, it might have evolved; the buyer needs to confirm which revision is offered today.
• Documentation creation date: A specification or process document created in 1993 may have been revised multiple times since, or it may still exist as an outdated record that was never replaced.
• Testing or certification date: Sometimes a supplier references 1993 as a historical benchmark. Unless the supplier ties the offered product revision to an active certification or current test plan, the date is not evidence of present performance.

Because these possibilities differ in meaning, the buyer’s best practice is to trace “1993” to its immediate context in the document. The buyer should capture the paragraph around the date, identify the document revision status, and ask what specific statement was intended to be supported by the historical mention.

Pricing and Supplier Clarity: What to Verify First

In any sourcing effort where pricing is mentioned together with supplier details, the very urgent issue is comparability. Price alone is rarely interpretable without confirming specifications, scope, delivery terms, and quality requirements. From an industry expert’s perspective, the procurement workflow should treat pricing as a hypothesis that must be validated through documentation.

When offers reference historical context (including 1993) or describe supplier history, procurement teams should verify at least the following:

• Scope of supply: What exactly is included (materials, services, documentation, packaging, testing, warranties)?
• Specification alignment: Are the referenced items in the same class/category as today’s requirements?
• Unit basis: Is pricing per item, per lot, per hour, per batch, or bundled with logistics?
• Incoterms or delivery conditions: Shipping terms materially affect “apples-to-apples” pricing comparisons.
• Quality assurance and test evidence: What tests were performed, by whom, and using which methods?

To make these checks more concrete, consider typical procurement failure modes where “1993” indirectly contributes to mistakes. For example:

• A supplier quotes a price using a legacy catalog configuration linked to a 1993 description, but the buyer is actually requesting a newer specification revision that requires different material grades or additional documentation.
• An offer claims continuity (“same product as since 1993”), yet the buyer discovers that packaging, labeling, or acceptance tests were updated later, and the offered package no longer matches the contract deliverables.
• The supplier provides a historical statement about process control, but the buyer lacks current evidence such as a current certificate of conformity, current test results, or revision-controlled specification documents.

Each of these scenarios highlights why procurement professionals separate historical narrative from contractual and evidentiary requirements. Pricing must be normalized to the contract deliverables and current specification. If the supplier’s price depends on assumptions that are not aligned with the buyer’s needs, the quote may look competitive while hiding real cost, compliance risk, or schedule impacts.

Objective Background: How Procurement Specialists Interpret Historical Signals

Procurement is not simply “finding a supplier”; it is reducing uncertainty under constraints like cost, risk tolerance, and timeline. Historically referenced terms—such as 1993—can function as one signal among many. Objectively, they may indicate good presence, but they do not automatically prove product safety, reliability, or manufacturing quality today.

Professional sourcing decisions rely on a layered evidence approach: documented quality systems, audit results (where applicable), conformity evidence, and clear contract terms. In regulated or safety-critical domains, buyers typically prioritize compliance artifacts over historical statements.

Layered evidence means procurement does not rely on a single document or a single claim. Instead, procurement teams triangulate:

• What is being supplied (specification and part revision evidence)
• How it is being controlled (quality system and process control evidence)
• How it is being verified (test evidence, inspection records, conformity statements)
• How changes are managed (change control, traceability, revision history)
• What the supplier is contractually committing to (terms, warranty, acceptance criteria)

Where “1993” fits into this model is as a potential indicator of documentation availability or business continuity, not as a substitute for any of the evidence categories above. If the supplier can use the 1993 reference to point to a revision history, a validated product evolution, or a consistent documentation record that remains active and aligned with the current specification, the date may support confidence. If the supplier cannot do that, the buyer should treat the date as irrelevant to compliance verification and proceed with evidence-based requirements.

From Evidence to Decision: A Practical Expert Workflow

Below is a disciplined approach procurement teams use to connect historical context (e.g., 1993) with current sourcing outcomes. The goal is not to “trust the past,” but to use the past to ask better questions.

In practice, workflow discipline matters because it prevents “narrative capture,” where a persuasive historical story fills gaps in missing evidence. A buyer may want to believe that a long-running product is stable. Yet the procurement process should remain grounded in what is being delivered now, what documents the supplier can provide now, and how the supplier will demonstrate conformity now.

A typical expert workflow includes:

• Document triage: Quickly categorize the 1993 mention as origin, catalog history, revision history, or unrelated background. Then determine whether the buyer needs to verify anything further based on that category.
• Specification mapping: Identify the buyer’s required specification revision and confirm whether the supplier’s offered product maps to the same or equivalent revision.
• Evidence request planning: Identify what evidence can close gaps—e.g., current test reports, current certificates, traceability statements, or quality system documentation.
• Comparability normalization: Normalize cost, delivery, acceptance testing scope, and warranty terms before ranking offers.
• Risk assessment: Evaluate what risk remains after evidence review and decide whether additional verification is needed (e.g., third-party inspection, batch sampling, or pilot shipments).
• Contractual alignment: Ensure that acceptance criteria and deliverable requirements explicitly reference the current evidence and current revision—not the historical narrative.

This approach transforms a potentially confusing historical reference into a structured input for decision-making. Instead of debating whether 1993 is “good,” the buyer focuses on whether the supplier’s current product and current documentation meet the contract’s needs.

Comparison Table: How Buyers Balance Historical Context vs. Present Evidence

The table can be interpreted as a principle: historical context is at most a gateway to questions. The buyer’s final confidence must be built from present-evidence requirements that are explicitly tied to the contract scope.

Step-by-Step Guide: How to Handle “1993” References in Supplier and Pricing Reviews

1. Capture the exact context where 1993 appears (catalog note, audit comment, product revision history, or supplier bio). Record the surrounding text and document revision status.
2. Confirm scope and unit basis for pricing. Normalize costs across offers by clarifying what is included: testing, documentation, shipping, and any required acceptance procedures.
3. Map the referenced product family to today’s specification. If the 1993-era item differs in materials, dimensions, performance, or compliance requirements, treat it as a different product unless proven otherwise.
4. Request present-day evidence that matches today’s requirements—such as current spec sheets, conformity evidence, and relevant test reports. Older documents should be used only to inform questions, not final acceptance.
5. Assess supplier quality system maturity using available indicators (quality management documentation, audit reports, and change-control practices).
6. Apply risk-based acceptance criteria. For higher-risk categories, require stronger verification (e.g., batch testing, traceability, or third-party verification where appropriate).
7. Document the decision rationale. Procurement is accountable decision-making; record why a historical reference was considered relevant or insufficient.
8. Re-check comparability before contract finalization. Differences in Incoterms, lead times, warranty scope, or testing protocols can invalidate early “apples-to-apples” comparisons.

To add operational depth, procurement teams often implement this as a repeatable checklist embedded into a sourcing workflow system (e.g., SRM or procurement tooling). This is important because “1993” may appear in multiple documents: supplier proposals, legacy certifications, cover letters, or even in spreadsheet comments from internal stakeholders. A standardized approach prevents inconsistent interpretation across buyers or across procurement cycles.

Below are practical ways to strengthen each step without turning the process into bureaucracy:

• Step 1 (Capture context): Save not only the paragraph containing 1993, but also the document identifier (document number, revision, effective date). If the supplier provides a PDF, capture screenshot evidence or attach the raw file to the procurement record so the team can verify later.
• Step 2 (Scope and unit basis): Require suppliers to explicitly fill out a pricing template with fields that match the buyer’s contract structure (unit price, quantity basis, inclusion/exclusion list, delivery terms, documentation deliverables, and warranty duration).
• Step 3 (Map product family): Use a “spec matching statement” where the supplier indicates how the offered part meets the requirement clauses. This prevents the buyer from relying on broad claims like “same product since 1993.”
• Step 4 (Request present-day evidence): Require evidence dates to align with production lead time and contract acceptance windows. “Old” test reports may be valid in some contexts, but procurement must confirm that they remain applicable to current manufacturing conditions.
• Step 5 (Assess quality system maturity): Ask for the most current quality system documentation applicable to the product category, plus summaries of audits or internal review outcomes if external audits are unavailable.
• Step 6 (Risk-based criteria): Translate risk into concrete contract language: sample sizes, inspection methods, acceptance thresholds, and consequences of nonconformance.
• Step 7 (Document rationale): Provide a short internal justification note in the procurement record describing why 1993 was treated as contextual and what evidence satisfied acceptance requirements.
• Step 8 (Re-check comparability): Perform a final “commercial normalization” pass focusing on incoterms, warranty, documentation deliverables, and any additional costs tied to compliance.

Conditions and Requirements Buyers Should Set in Procurement

To keep sourcing decisions objective and defensible, set contract and evaluation requirements that respond directly to uncertainty introduced by historical references like 1993. Typical conditions include:

• Document recency: require current revision numbers and applicability statements.
• Evidence-to-spec linkage: test reports must reference the same revision/specification used in procurement.
• Change-control transparency: suppliers should explain what has changed since legacy documentation references, including materials and process modifications.
• Nonconformance handling: define acceptance criteria, escalation steps, and corrective action expectations.
• Audit and traceability (as applicable): for regulated or critical products, define what traceability and audit rights are needed.

Even when a supplier is well-established, a buyer benefits from writing requirements in a way that “forces” alignment between deliverables and evidence. Historical references can create loopholes if contracts are too vague. For example, if a contract does not specify which specification revision the supplier must meet, the supplier may reference a legacy configuration that is not truly equivalent. The contract should therefore make it difficult for ambiguity to survive.

To further reduce risk, buyers can incorporate additional, more operational requirements:

• Revision control expectations: Require that the supplier’s deliverable identification (part number, drawing revision, software version if applicable) matches the contract requirements.
• Certificate of conformity requirements: Define the minimum content of certificates, including which specification clauses are covered and which production batch/lot is certified.
• Documentation deliverables schedule: Specify when documentation must be provided (before shipment, at shipment, or after delivery) so that the buyer can complete inspections and compliance checks on time.
• Labeling and packaging requirements: Many procurement failures relate to documentation and labeling mismatches rather than manufacturing itself. Buyers should confirm packaging labels, shipping documents, and instructions match the contract needs.
• Acceptance test procedure: Ensure the contract states the acceptance test method or references a standard procedure, and clarifies who performs tests (supplier, third party, or buyer).

These requirements collectively reinforce the core idea: a historical date is not a compliance substitute. Compliance must be tied to current deliverables, current documentation, and current acceptance evidence.

Industry Perspective: How Specialists Reduce Uncertainty

Experienced procurement and quality managers approach historical signals—such as a 1993 mention—like a documentary clue rather than a guarantee. The key is to avoid cognitive shortcuts (e.g., “older means safer” or “supplier has been around forever, so it must be fine”). Instead, specialists ask whether the supplier can demonstrate that the current product meets current expectations.

In mature supply chains, the very reliable evidence is typically the combination of:

• Conformity evidence aligned to the buyer’s requirement documents
• Quality system documentation that supports consistent manufacturing and control
• Clear change-control history so buyers can understand continuity and differences since 1993

One reason professionals prefer these evidence categories is that they help prevent two major procurement issues:

• Equivalence errors: The supplier claims continuity, but the underlying product has changed (materials, tolerances, processes, compliance classification). Without mapping to current specifications, the buyer might accept the wrong equivalence.
• Evidence mismatch errors: The supplier provides documents, but they are outdated or tied to a different revision, location, or production window. Without revision alignment, documentation may be technically “real” but not contract-relevant.

To handle these challenges, specialists often insist on explicit evidence linkage. For example, rather than accepting a “1993” catalog claim, the buyer asks: “Which revision of the specification does this product meet? Provide the current conformity evidence referencing that revision. Provide the test reports tied to this batch/lot. Explain any changes since the historical reference.” If the supplier cannot provide this, the buyer treats the supplier’s historical narrative as non-usable for acceptance and may require additional testing or delayed acceptance until evidence is sufficient.

Deepening the Discussion: Common Real-World Patterns Behind “1993”

It can be helpful to examine recurring patterns in how “1993” appears in procurement workflows. While the exact phrasing differs across suppliers and industries, the underlying themes are surprisingly consistent. Understanding these patterns helps buyers respond systematically rather than reactively.

Pattern 1: “Since 1993” as a Business Credibility Narrative

Suppliers sometimes write “Since 1993” to communicate stability and experience. While business longevity can be a positive sign, it does not substitute for current product and process evidence. Buyers can accept this narrative as context but should still verify:

• Which facility(s) produced the offered items
• Whether the production process is still the same or has been updated
• Whether current compliance requirements have changed since 1993
• Whether certifications, if any, remain active and apply to the specific product category and facility

In practice, experienced buyers treat “Since 1993” the way they treat “we have always done it this way”: as a prompt to ask for current process control evidence and current validation results. If the supplier cannot show current documentation, the narrative becomes unhelpful for acceptance.

Pattern 2: “1993” as the Origin of a Product Family

Another common scenario is where the supplier indicates the product family was originally launched in 1993, sometimes implying that today’s product is essentially the same. This can be partly true—some design concepts may persist—but the buyer must confirm whether manufacturing processes, materials, regulatory classifications, tolerances, and performance requirements have evolved.

A buyer should therefore request:

• Current part number(s) or drawing numbers with revision level
• Current specification sheets and compliance statements
• Evidence of changes since initial design (a change-control summary)
• Batch/lot-level conformity evidence

The risk here is that suppliers may treat “product family continuity” as equivalence to current performance. Procurement must separate conceptual continuity from contractual equivalence.

Pattern 3: “1993” on Legacy PDFs and Unclear Document Governance

In many organizations, suppliers attach old PDF documents that include a date like 1993 in a footer or header, or they reference it in the context of “originally issued” documentation. Buyers should not automatically assume that these documents are current or applicable.

To address this, buyers can require suppliers to provide:

• The latest revision date and revision number
• The document control status (superseded vs. active)
• A mapping from older documents (if included) to the current contract-relevant specification
• Document effective dates and applicability statements

This practice reduces the probability of using stale evidence. It also encourages better supplier document governance, because the supplier must identify what is active and what is historical.

Pattern 4: “1993” as a Pricing Reference Point

Occasionally, pricing narratives may reference historical stability or baseline costs dating back to 1993. Even if the supplier meant to convey long-term cost structure, procurement should not treat historical pricing narratives as justification for current prices.

Instead, buyers should compare offers using contract deliverables and current scope. This means verifying:

• Whether the quote includes required tests, certifications, and documentation deliverables
• Whether warranty scope matches contract terms
• Whether packaging and labeling costs are included
• Whether shipping and logistics costs are included and aligned to the same incoterms

When suppliers embed historical pricing cues, buyers should treat those cues as marketing narrative unless the supplier can demonstrate how current unit pricing maps to current scope and evidence.

Pattern 5: “1993” in Compliance or Regulatory Discussions

In some industries, historical dates might be mentioned alongside regulatory milestones or historical regulatory frameworks. For buyers, this is a particularly sensitive pattern because compliance requirements often evolve. A reference to 1993 might indicate a prior compliance route or previous standard, but it may not reflect current regulations.

Buyers should therefore insist on:

• Current applicable regulatory standards or regulatory clauses
• Evidence that current product meets the applicable standard revision
• Any notified body documentation if relevant
• Where applicable, conformity assessment documentation tied to the current product revision

This is where the “treat as context, not proof” principle becomes critical. In regulated domains, it is not enough that the supplier “was compliant in 1993” or that a legacy process was approved. What matters is the current compliance state under current requirements.

Practical Guidance: What to Ask When “1993” Shows Up

Since procurement professionals treat 1993 as context, the buyer’s next step is to ask targeted questions. Below is a question set that maps the historical reference to the evidence needed for procurement decisions. You can treat these as prompts to structure supplier communication.

Clarifying Questions About the Reference

• What does 1993 specifically refer to (company founding, product launch, document issue date, testing date, or certification milestone)?
• Which document or product revision is associated with the 1993 reference?
• Has the product changed since then? If yes, what has changed (materials, dimensions, performance requirements, processes, compliance classification)?

Evidence Questions Tied to the Buyer’s Current Requirements

• What current specification revision does the offered item meet?
• Provide current conformity evidence referencing the same specification revision.
• Provide test reports tied to the offered batch/lot and the current revision.
• Provide certificates of conformity (or equivalent documents) that specify coverage scope clearly.

Commercial and Scope Questions Tied to Pricing

• Does the quote include testing and documentation deliverables required by the contract?
• What is the unit basis (per item, per lot, per batch)?
• What delivery terms and incoterms apply?
• Are there additional costs for acceptance testing, rework, or corrective actions?

Risk and Acceptance Questions

• What nonconformance handling process applies if the delivered items do not meet acceptance criteria?
• What traceability does the supplier provide (batch/lot identifiers, serial numbers where applicable)?
• What additional verification can the supplier provide for higher-risk requirements?

When you ask these questions, you prevent “1993” from becoming a narrative shield. The supplier must respond with evidence and mapped scope. If they cannot, the buyer should adjust risk posture and acceptance conditions accordingly.

Procurement Documentation: How to Record the Decision

Even if procurement teams follow evidence-driven steps, documentation of the decision rationale is often what separates defensible sourcing from ad hoc justification. The buyer should record what the historical reference meant, how it influenced evaluation, and why it did or did not justify acceptance.

A strong procurement record might include:

• The exact excerpt where 1993 appears
• Document identifiers and revision status for both supplier-provided and buyer-required documents
• Evidence artifacts received (certificates, test reports, quality system summaries)
• A mapping statement showing how the offered product revision matches the requested specification
• Any deviations or clarifications agreed in writing
• Commercial normalization notes (incoterms, unit basis, inclusions/exclusions)
• Risk assessment outcome and acceptance criteria

By explicitly recording why a 1993 reference was treated as contextual rather than proof, the buyer ensures internal accountability and supports future audits or post-award reviews.

Quality Assurance Integration: Aligning Procurement and Quality

Procurement decisions are stronger when procurement and quality assurance function as partners rather than separate silos. Historical references like 1993 often first appear in procurement communications, but the quality team is usually the group best equipped to evaluate whether evidence is adequate and properly tied to current specifications.

To integrate quality assurance:

• Route historical references to the quality review queue whenever they appear in claims of continuity, process stability, or compliance history.
• Require evidence templates so suppliers provide test reports, certificates, and conformity statements in a format quality teams can validate quickly.
• Perform revision checks jointly: procurement ensures commercial comparability, quality ensures technical alignment to current revision/spec.
• Agree on acceptance triggers: e.g., if a supplier provides outdated evidence, what additional verification is required before release?

This integration reduces the risk that procurement might accept a supplier narrative simply because the quote seems good, while quality might later discover mismatches.

Risk-Based Acceptance: Turning Evidence Gaps into Contract Actions

When 1993 appears, the likely risk is not that the date is “bad,” but that the historical narrative might be masking an evidence gap. If current evidence is missing or not clearly tied to contract requirements, the buyer should translate that risk into acceptance actions.

Examples of risk-based acceptance actions include:

• Additional incoming inspection for initial shipments
• Batch sampling with predefined sampling plans
• Third-party verification for higher-risk categories
• Hold points where shipment is delayed until evidence is received and verified
• Rejection or remediation triggers if evidence is not revision-aligned or fails to cover contract requirements

These actions ensure that the buyer does not “force acceptance” based on historical context. Instead, acceptance is tied to the ability to verify conformity under current requirements.

How to Compare Offers When “1993” Creates Ambiguity

Sometimes “1993” appears in a way that makes it unclear whether the supplier is quoting the buyer’s exact requirement or a legacy equivalent. In these cases, procurement teams need to compare offers without letting ambiguous historical claims distort the ranking.

A robust method for comparison includes:

• First ensure technical comparability: only rank offers that map to the required specification revision (or clearly documented equivalent with evidence).
• Then normalize commercial terms: align incoterms, warranties, documentation inclusions, and acceptance testing responsibilities.
• Assign cost impacts to evidence differences: if one supplier must provide additional testing or documentation to match requirements, adjust the normalized cost accordingly.
• Separate “commercial price” from “total compliance cost”: the latter includes additional costs needed to close evidence gaps.

When these steps are followed, historical references like 1993 cannot unfairly justify a low price. If the supplier’s quote is low because it omits evidence deliverables or assumes a different revision, the normalized comparison will reveal the real cost to meet contract requirements.

Supplier Responsibilities: What Good Replies Look Like

If you are a buyer, it is useful to define what “good evidence” looks like to suppliers. The supplier’s response quality can vary widely, especially when they reference historical materials.

Good supplier responses to a 1993 reference usually include:

• Clear explanation of what the date refers to
• Current revision-controlled specifications
• Conformity evidence tied to the exact specification revision
• Test reports tied to the offered batch/lot
• A change-control summary showing how the product evolved since the historical reference (if evolution is relevant)
• Explicit mapping between their documents and the buyer’s contractual deliverables

If suppliers instead respond with vague statements (“same as before,” “we have been doing it since 1993,” “our experience proves quality”), the buyer should treat this as insufficient. The buyer’s acceptance must depend on verifiable, revision-aligned evidence.

FAQs

1) What does a “1993” reference usually mean in supplier documentation?

A 1993 reference often indicates historical context—such as when a product line started, when a catalog entry was created, or when a process description was first recorded. It can be informative, but it usually does not replace current compliance or quality evidence.

2) Should buyers treat “1993” as proof of quality?

No. A professional approach is to treat 1993 as background information and require present-day documentation that matches the current specification, revision, and compliance requirements.

3) How do you compare prices when historical notes are included?

Normalize the offers by verifying scope, unit basis, delivery terms, and inclusion of testing/documentation. Historical notes related to 1993 should not be used as a direct price justification unless they connect to verifiable, current specifications.

4) What evidence should a supplier provide to make historical references usable?

Suppliers should provide current revision-controlled specifications, conformity evidence, test reports tied to the same revision, and a clear explanation of changes since the 1993 context—so the buyer can confirm continuity or updated performance.

5) Are there universal sourcing “conditions” buyers should include?

Very buyers benefit from requiring document recency, evidence-to-spec alignment, defined acceptance criteria, and nonconformance handling terms. The exact strength of requirements depends on risk and regulatory context.

6) What is the biggest procurement mistake involving historical references?

Over-reliance. The common error is assuming that a long-standing reference—like 1993—automatically guarantees current capability. The correct approach is evidence linkage to current requirements.

Conclusion: Use “1993” to Ask Better Questions

A well-managed procurement strategy treats 1993 as a contextual anchor, not a conclusion. By combining disciplined price normalization, present-day evidence requirements, and risk-based acceptance criteria, buyers can interpret supplier references responsibly and make defensible sourcing decisions. The result is not only better cost comparability, but also improved quality confidence grounded in verifiable documentation rather than historical assumption.
