Note 5             Capitalization

 

In May 2013, the Board of Directors of the Company approved a five-for-four stock split to be effected in the form of a 25% stock distribution to shareholders of record on August 16, 2013.  Common shares outstanding do not include shares held by the Company in treasury.  The new shares were distributed on September 1, 2013.  Aqua America’s par value of $0.50 per share did not change as a result of the common stock distribution, and $17,655 was transferred from capital in excess of par value to common stock to record the stock split.  All common share, per common share, stock unit, and per stock unit data, for all periods presented, has been adjusted to give effect to the stock split.    |
