Note 5 – Cash and Cash Equivalents

Certain debt securities which are collateralized by rigs are government guaranteed through the Title XI program of the U.S. Department of Transportation's Maritime Administration (“MARAD”).  At the Company's request, MARAD has waived certain windstorm insurance coverage requirements under the loan agreements, for which the Company agreed to a covenant to maintain a minimum cash balance of up to $25 million.  The minimum amount varies depending on the geographical location of rigs, and is currently $10 million.  Rowan remains subject to restrictions on the use of certain insurance proceeds should the Company experience future windstorm losses.  Each of these security provisions will be released by MARAD should Rowan be able to obtain windstorm coverage that satisfies the original terms of its debt agreements.
