Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a word-for-word translation like 'отношение потерь'. In financial contexts, it is a specific 'коэффициент убыточности' or 'коэффициент ущерба'.
- Do not confuse with 'loss rate' (скорость потерь), which implies a rate of change over time.
Common Mistakes
- Using 'loss ratio' to mean simply 'percentage of losses' without reference to an earned base (e.g., premiums).
- Incorrect preposition: 'loss ratio *of* premiums' should be 'loss ratio *to* premiums' or simply 'loss ratio'.
- Treating it as a plural: 'The loss ratios *are*' is correct only when referring to multiple distinct ratios.

FAQ
Frequently Asked Questions
It indicates an underwriting loss, meaning the company paid out more in claims and expenses than it earned in premiums for that period.
No. The loss ratio relates to claims and loss adjustment expenses. The expense ratio covers operational costs (salaries, marketing). Together, they form the combined ratio.
Yes, but it's rare and usually metaphorical or comparative, e.g., in sports to describe games lost versus games played.
Earned premium is the portion of the written premium that applies to the expired part of the policy period. The technical loss ratio uses earned premium, as it aligns the premium with the period of risk.
