extra ordinary meeting

A company has to hold 3 types of meeting 

1. statutory meeting (only in case of limited co having share capital )  soon after -commencement on business-  once in life time  
2. annual general meeting once in every canender year

 any meetning other then these  2 are called EGM, which is held between 2 AGM , to discuss some important matters for which Board can not wait till AGM

There may be certain matters which require immediate attention and action as well as consent from the members of the company; for e.g. Increase in capital, Shifting of registered office from one state to other, Change in objects, etc. A Company cannot wait till the next annual general meeting. So the company holds an extra-ordinary general meeting (EGM) to give effect to its resolutions which requires members' consent. 

Any general meeting held between two AGMs is an EGM.
