As a result, in the second quarter of 2013, the Company recorded &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$169,000&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$85,000&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; of amortization into income relating to year ended December 31, 2012 and the first quarter of 2013, respectively.

This application also reduced the surcharge by 0.09% for the prior year reconciliation adjustment which expired April 1, 2013.&amp;#160;&amp;#160;On January 30, 2013, Connecticut Water filed for a 0.10% reconciliation adjustment for the 2012 shortfall in WICA, to become effective April 1, 2013.&amp;#160;&amp;#160;On March 25, 2013, the PURA approved an additional 1.06% surcharge, effective April 1, 2013.  Additionally, on March 27, 2013, the PURA approved a 0.10% reconciliation adjustment, effective April 1, 2013.  As of April 1, 2013, Connecticut Water's cumulative WICA surcharge was 6.80%.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;On July 25, 2013, Connecticut Water filed a WICA application with the PURA requesting an additional 1.09% surcharge to customers' bills, representing approximately $5.6 million in WICA related projects.

On July 1, 2013, Connecticut Water submitted an application to the PURA seeking formal approval by PURA of the Settlement Agreement. &lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The Settlement Agreement contemplates that Connecticut Water will adopt temporary and proposed regulations issued by the Internal Revenue Service ("IRS") that allows the Company to adopt an alternative method for determining how expenditures related to tangible property can be treated for federal tax purposes for tax years beginning on or after January 1, 2012.&amp;#160; This tax accounting method change will treat certain expenditures that the Company historically capitalized for tax purposes, as a deductible repair expense on its tax return.&amp;#160; The adoption of the tax accounting method change will allow Connecticut Water to record a favorable &amp;#8220;catch up adjustment&amp;#8221; on the Company's consolidated 2012 federal tax return to be filed in September 2013.
