This bonus is capped at the Market Tenure category maximum of 30 points.
Market Maturity Scores reflect a manufacturer's observable presence and tenure in the Australian market. They are not product quality judgements, performance ratings, or purchase recommendations. A lower score may indicate a newer market entrant rather than an inferior product.
