Cash and cash equivalents are primarily held in bank accounts and overnight investments. We maintain our bank deposit accounts with large financial institutions in amounts that often exceed federally-insured limits. We have not experienced any losses in such accounts. Our mortgages and other notes receivable consist primarily of secured loans on facilities. </font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our financial instruments, principally our investments in marketable securities and notes receivable, are subject to the possibility of loss of the carrying values as a result of either the failure of other parties to perform according to their contractual obligations or changes in market prices which may make the instruments less valuable. We obtain collateral in the form of mortgage liens and other protective rights and continually monitor these rights in order to reduce such possibilities of loss. We evaluate the need to provide for reserves for potential losses on our financial instruments based on management's periodic review of our portfolio on an instrument-by-instrument basis.</font></div></div>

In the event that our financing commitment to a potential borrower or lessee expires, the related commitment fees are recognized into income immediately. Commitment fees may be charged based on the terms of the loan or lease agreements and the creditworthiness of the parties.</font></div></div>

Actual results could differ from those estimates.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div></div>
