CONCENTRATIONS
OF CREDIT RISK
Financial
instruments that potentially subject us to concentrations of credit
risk consistfalsefalsefalseDescription of any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. The entity should inform financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date. Disclosure of any financial instrument credit risk concentration also should indicate the maximum amount of loss that would be incurred upon complete failure of the counterparty to perform and the entity's collateral policies or other policies that limit the loss exposure. This element may be used as a single block of text to encapsulate the entire disclosure including data and tables.Reference 1: http://www.xbrl.org/2003/role/presentationRef
