Our evaluation of impairment of unproved properties occurs, at a minimum, on a quarterly basis. For the year ended June 30, 2013, we transferred $4.1 million of Mississippi Lime property cost to the full cost pool as initial quantities of hydrocarbon production were indicative of impairment. During the corresponding prior year period, we transferred approximately $2.2 million of impaired assets, reflecting principally Woodford Shale properties, from our unevaluated pool to our full cost pool.         The following table provides a summary of costs that are not being amortized as of June 30, 2013, by the fiscal year in which the costs were incurred: <div style="POSITION: relative;
