In the 2013 fourth quarter, Griffin completed the sale of approximately 90 acres of undeveloped land for approximately $9,000 in cash, before transaction costs (the “Windsor Land Sale”). The land sold is located in Windsor, Connecticut and is part of an approximately 253 acre parcel of undeveloped land that straddles the town line between Windsor and Bloomfield, Connecticut. Under the terms of the Windsor Land Sale, Griffin and the buyer are each constructing roadways connecting the land parcel sold with existing town roads. The roads being built will become new town roads, providing public access to the remaining acreage in Griffin’s land parcel. As a result of Griffin’s continuing involvement with the land sold, the Windsor Land Sale is being accounted for under the percentage of completion method. Accordingly, the revenue and pretax gain on the sale are being recognized on a pro rata basis in a ratio equal to the percentage of the total costs incurred to the total anticipated costs of sale, including costs of the required roadwork. Costs included in determining the percentage of completion include the cost of the land sold, allocated master planning costs and the cost of road construction. At the closing of the Windsor Land Sale, cash proceeds of $8,860 were placed in escrow for the potential purchase of a replacement property in a like-kind exchange under Section 1031 of the Internal Revenue Code of 1986, as amended. The proceeds held in escrow (including interest earned) were returned to Griffin in the 2014 second quarter, as a replacement property was not acquired.

As of August 31, 2015, approximately 89% of the total costs related to the Windsor Land Sale have been incurred; therefore, from the date of the Windsor Land Sale through August 31, 2015, approximately 89% of the total revenue and pretax gain on the sale have been recognized in Griffin’s consolidated statements of operations. Griffin’s consolidated statements of operations for the 2015 third quarter and 2015 nine month period include revenue of $1,176 and $2,247, respectively, and a pretax gain of $1,014 and $1,763, respectively, from the Windsor Land Sale. Griffin’s consolidated statements of operations for the 2014 third quarter and 2014 nine month period include revenue of $904 and $1,274, respectively, and a pretax gain of $674 and $950, respectively, from the Windsor Land Sale. As of August 31, 2015, Griffin has recognized total revenue of $8,020 and a total pretax gain of $6,111 from the Windsor Land Sale. The balance of the revenue and pretax gain on sale will be recognized when the remaining costs are incurred, which is expected to take place mostly in the fourth quarter of fiscal 2015. Deferred revenue on Griffin’s consolidated balance sheet as of August 31, 2015, includes $948 related to the Windsor Land Sale that will be recognized as the remaining costs are incurred. The total pretax gain on the Windsor Land Sale is expected to be approximately $6,833 after all revenue is recognized and all costs are incurred. While management has used its best estimates, based on industry knowledge and experience, in projecting the total costs of the required roadways being constructed, increases or decreases in future costs as compared with current estimated amounts would reduce or increase the gain recognized in future periods.

The Florida farm that had been used by Imperial prior to being shut down in fiscal 2009 has been leased to a private company grower of landscape nursery products since fiscal 2009. In the 2015 second quarter, the tenant that leases the Florida farm gave notice of its intent to exercise the purchase option for the Florida farm under the terms of its lease for approximately $4,100. On June 1, 2015, Griffin received a deposit of $400 as required under the terms of the lease agreement. In August 2015, that tenant informed Griffin that it would not close on the purchase of the Florida farm. Imperial and the tenant subsequently entered into a Holdover and Settlement Agreement (the “Agreement”) which permits the tenant to continue to lease the Florida farm at an agreed upon rental rate through April 30, 2016. The Agreement also stipulates that Imperial is entitled to retain the deposit against the purchase price made by the tenant when it exercised its option to purchase the Florida farm, therefore, the $400 deposit is reflected as property sales revenue in Griffin’s consolidated statements of operations for the 2015 third quarter and 2015 nine month period.
