The original project plan projected total costs of $24,000,000 of capital expenditures of which $16,800,000 is to be funded by the NTIA grant. Our investment in the project was anticipated to be approximately $7,200,000 or 30% of the estimated total project cost. Total project costs incurred through June 30, 2013 are $20,368,000. Due to scope revisions and effective cost management, we anticipate completing the project at a total cost of approximately $22,000,000 to $23,000,000 reducing our investment to approximately $6,600,000 to $6,900,000. We began capitalizing costs associated with this project in 2010 and began receiving grant funds in June 2011.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; font-family: ''Times New Roman'', Times, serif;
