The income statement sells a similiar story of growth since 2001.
VL says that earnings have grown from 50 cents a share to $1.71 in 2008. Dividends tell a similair story-They have grown from 12 cents a share to 34 cents in 2008.
In addition, they are a financially strong company with no long term debt, and a very good current position of over 3/1.
They are small enough to continue their fast growth; but secure enough to not go broke.
I think it's cheap because it's in a very un-sexy field.
