Payments under the captive agreement are for the fiscal 2013 year-to-date loss fund as estimated in advance using actuarial methodology. The captive agreement provides that we will share in the underwriting results, good or bad, within a $250,000 per occurrence layer of loss through retrospective premium adjustments. The Company reached an agreement with the District of Columbia in November 2011 concerning the assessed value of the Company’s property resulting in a credit due to the Company. The taxes previously paid relating to the property were capitalized to the cost of the land as we are actively pursuing development of the property. The entry to record this agreement was to establish a receivable for the taxes and to credit the cost of the land in the amount of $2,311,000. It is anticipated that the remaining $1,576,000 receivable as of September 30, 2013 including interest will be collected in fiscal 2014.
