How Korea grades its
sole proprietors

Korea's Financial Services Commission evaluates roughly 900,000 sole proprietors on trade credit, revenue stability and growth, and publishes the result in three grades: excellent, good, and below average. Pick a region and an industry to see how that market is graded against the national picture.
