	us-gaap	Derivatives Methods Of Accounting Hedging Derivatives DerivativesMethodsOfAccountingHedgingDerivatives	The effective portion of changes in the fair value of the derivatives that are designated as cash flow hedges are being recorded in accumulated other comprehensive income and will be subsequently reclassified into earnings during the period in which the hedged forecasted transaction affects earnings for as long as hedged cash flows remain probable. During the next twelve months, we estimate the cash flow hedges in place will reduce interest expense by approximately $1.1 million.The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of the derivative. This analysis reflects the contractual terms of the derivative, including the period to maturity, counter party credit risk and uses observable market-based inputs, including interest rate curves, and implied volatilities. The fair value of the interest rate swap is determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.
