Anyone Find Reading 31 Not Very Well-Written? Internet, alternate, interested, effective

Hi everyone,
I was wondering if anyone else is finding reading 31 in the CFA Curriculum (Income Taxes) to be not very well-written?  I have found that I’ve had to refer to other sources of information for this reading – for example the authors don’t explain what statutory taxes are vs. effective taxes, and I had to look that up in an alternate source on the Internet.  I didn’t find myself doing that in previous readings.  Would be interested in hearing your thoughts.
Thanks!
