In order to apply hedge accounting, the transaction must be designated as a hedge and it must be highly effective. The hedging instrument’s effectiveness is assessed utilizing both a dollar offset and regression testing approach at the inception of the hedge and either a dollar offset and regression testing approach or qualitative analysis on at least a quarterly basis throughout its life. All of the transactions that the Company has designated as hedges are cash flow hedges. The effective portion of the change in fair value on a derivative instrument designated as a cash flow hedge is reported as a component of other comprehensive income and is reclassified into earnings in the period during which the transaction being hedged affects earnings. The ineffective portion of the hedges is recorded in earnings in the current period.</span></div>

Management evaluates estimates on an ongoing basis, including those related to residual values, estimated asset lives, impairments, bad debts and credit losses. Estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.</span></div><div style="text-align:justify;text-indent:18pt"><span><br/></span></div><div style="text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Management believes that the accounting policies on revenue recognition, useful life of equipment, asset residual values, asset impairment, allowance for doubtful accounts, and allowance for credit losses are critical to the results of operations.</span></div><div style="text-align:justify;text-indent:18pt"><span><br/></span></div><div style="text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">If the useful lives or residual values are lower than those estimated, upon sale of the asset a loss may be realized.

Management opts for security of principal as opposed to yield. Concentrations of credit risk with respect to lease receivables are limited due to the large number of customers comprising the customer base, and their dispersion across different geographic areas. Some lessees are required to make payments for maintenance reserves at the end of the lease however, this risk is considered limited due to the relatively few lessees which have this provision in the lease. The Company enters into interest rate swap agreements with counterparties that are investment grade financial institutions.</span></div>
