English to Arabic Bus/Financial Surveying Human resources

The actual salaries are benchmarked against the relevant market lines.

Actually I have searched for the term and found "capital market line" which seems irrelevant here. The Arabic translations varied from خطوط و متطابات and قواعد . I am clueless as to which one to choose (قواعد أم خطوط). I appreciate it if someone can enlighten me with helpful information.
