(a)  In 1991, operating results included a special charge of $209
     million ($160 million after tax).  As a result, earnings were
     insufficient to cover historical fixed charges by $169 million.
     Excluding the effect of the special charge, earnings would have 
     been sufficient to cover historical fixed charges by $40 million.
