Current assets ÷ current liabilities. A ratio above 2× earns full marks; between 1–2× scores partially; below 0.5× scores minimal points.

Longevity6/15 pts

One point per year of operation since incorporation, capped at 15. Older companies have a proven track record.

Full 15 points when both annual accounts and confirmation statement are filed on time. Points are deducted for each overdue filing.
