reference letter - working certificate

Dear all,
I got a reference letter from my previous employer, but as a non English native speaker, I'm not sure if it really shows my qualities.

Mrs X,.... has worked for xx from 1st Sep 2007 until 31 Oct. 2010 as Assistand Manager Planning.

Her role and responsibiliies included:

budget planning
analyse of monthly / yearly sales figures
preparing different financial analyses and Key performance indicatiors
preparation of different statistics
reporting to CFO and HQ
Support in financial matters

Mrs X has a broad job experience in Planning and always fulfilled her tasks independently and to our fullest satisfaction. She brings along all the required know-how for the above-named duties and responsibilities and personally combines them with high engagement, target orientation and a structured working style. As a team player she was appreciated by management and colleagues alike.

Mrs X leaves our company upon her own request by the end of Oct. 2010. We would like to thank Mrs. X for her contribution to Y and wish her all the best.

What's your opinion? Is this a good reference letter?

Thanks for your help!
