Which tense is better for a report like this?

Dear all,

I have to write an annual report for 2009-2010. The report is expected to be issued by the end of August/early in September). The annual report actually mentions things happened and agenda discussed during the session between September 2009 and July 2010. Shall I use present tense or past tense?

An example is given below:

During the session, the board discusses/discussed various issues, including the business plan for 2009-10, salary adjustments, site visits, etc.

• In this context, is present tense better than past tense or the other way around?

• 
  Is time a concern here? Given that it is still 2010, but the annual report is for 2009-2010.

• 
  Is the issue date or the time I put pen to paper that matters?
• 
  When some issues are ongoing and will continue discussing in the 2010-11 session, is it better to use present tense?

Finally, what are the grammar points for the above questions? 

Thanks a lot. 

Yours truly,

Benevolence
