explain: profitability ratios, solvency ratios, and liquidy ratios

Dear Neteno, 

Profitability ratios are "Used to measure how successfully a business
earns a return on its investment." (Glossary P -
<http://www.crfonline.org/orc/glossary/p.html>). In other words, they
help "to explain the profitability of an entity during a defined
period of time." (SOURCE: Glossary,
<http://wps.pearsoned.co.uk/wps/media/objects/1065/1090612/glossary.html>).

Solvency ration is a "Key ratio representing the relative size of
solvency capital. The solvency ratio is calculated as solvency capital
in relation to net premiums written, excluding portfolio premiums.
Compare with solvency capital. Solvency requirement (solvency margin)
The capital required for insurance operations from the viewpoint of
the supervisory authorities. The requirement is based on the
historical claims outcome or gross premiums written, whichever is
higher." (SOURCE: if-insurance,

The liquidity ratio (please note that you've misspelt the term) is
defined as: "A ratio that shows what proportion of an entity?s assets
can be readily turned into cash in the short term." (SOURCE: Glossary,
<http://wps.pearsoned.co.uk/wps/media/objects/1065/1090612/glossary.html>).
