New Accounting Pronouncement [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	2. New Accounting Pronouncement In April 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity ("ASU 2014-08"). Under ASU 2014-08, only disposals representing a strategic shift in operations (for example, a disposal of a major geographic area or a major line of business) will be presented as discontinued operations, while significant continuing involvement with such dispositions will no longer preclude discontinued operations classification. As current GAAP generally requires companies that sell a single investment property to report the sale as a discontinued operation, the implementation of ASU 2014-08 will result in us reporting only sales that represent strategic shifts in operations as discontinued operations. ASU 2014-08 will also require additional disclosures for discontinued operations as well as for material property dispositions that do not meet the new criteria for discontinued operation classification. ASU 2014-08 is effective for fiscal years beginning on or after December 15, 2014, with early adoption permitted only for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. It is our intention to adopt ASU 2014-08 during the three-month period ended June 30, 2014.

ASU 2014-08 will also require additional disclosures for discontinued operations as well as for material property dispositions that do not meet the new criteria for discontinued operation classification.
