[1] Dividends declared were $0.70 per share for the years ended June 30, 2014 and 2013. This is based on total number of shares outstanding. However, Greene County Bancorp, MHC, , the owner of 54.7% of the Company's shares outstanding waived its right to receive dividends during the year ended June 30, 2014 and the six months ended June 30, 2013, but did not waive its right to receive dividends declared during the six months ended December 31, 2012. The MHC's ability to waive the receipt of dividends is dependent upon annual approval of its members as well as receiving the non-objection of the Federal Reserve Board. The MHC may waive dividends for the 12 months subsequent to its latest approval which was obtained on February 19, 2014.
