Legal Definitions - good-faith margin

The term good-faith margin refers to a reasonable and acceptable allowance for minor errors, discrepancies, or deviations from a precise standard, provided that the person or entity making the error acted honestly, sincerely, and without any intention to deceive, mislead, or defraud. It acknowledges that perfect precision is not always achievable, and minor imperfections are tolerated when the underlying conduct demonstrates integrity and a genuine effort to comply with obligations or standards.

• Example 1: Construction Contract Compliance

  A construction company is building a commercial office space according to detailed architectural blueprints. One specification requires a particular support beam to be exactly 20 feet long. Due to standard manufacturing tolerances for steel and the practicalities of on-site installation, the installed beam measures 19 feet, 11 and 15/16 inches. The client initially raises a concern about the deviation.

  This illustrates a good-faith margin because the contractor used industry-standard materials and installation techniques, making every reasonable effort to meet the exact specification. The slight, almost imperceptible deviation does not compromise the structural integrity or functionality of the building. Since the contractor acted diligently and without intent to cut corners, this minor variance would typically fall within an acceptable good-faith margin, meaning it would not be considered a breach of contract.

• Example 2: Regulatory Data Reporting

  A pharmaceutical company is required to submit quarterly reports to a regulatory agency detailing the exact quantities of certain controlled substances used in research. In one report, a data entry clerk accidentally inputs "125.5 kg" instead of the correct "125.0 kg" for a specific compound. The company discovers this minor error during an internal audit before the agency reviews the report and immediately submits a corrected filing with an explanation.

  Here, the 0.5 kg difference is a minor data error. Because the company promptly identified and corrected the mistake, demonstrating transparency and a genuine effort to comply with reporting requirements (acting in good faith), the regulatory agency would likely consider this within a good-faith margin. They would typically not impose penalties, recognizing it as an unintentional administrative oversight rather than an attempt to misrepresent data.

• Example 3: Professional Service Estimation

  A financial advisor provides a client with an estimated projection for their investment portfolio's growth over the next five years, based on current market conditions and historical data. The advisor clearly states that this is an estimate and not a guarantee. After five years, the portfolio's actual growth is slightly lower than the initial projection due to unforeseen minor market fluctuations that no one could have perfectly predicted.

  This scenario demonstrates a good-faith margin because the financial advisor used professional methodologies and their best judgment to create the projection, acting honestly and without intent to mislead the client. The slight difference between the estimated and actual outcome is an acceptable variance within a good-faith margin, as perfect foresight in financial markets is impossible. The advisor fulfilled their duty by providing a reasonable estimate based on available information at the time.
