ConclusionsConclusionsConclusionsConclusions

• Loss of 2nd Vendor for Superconducting Strand Removes Luxury of Generous Slack in Strand Procurement Schedule; Remaining slack now ~ 3 months

• 1st Vendor’s Superconducting Strand is of Excellent Quality; Responsive to Increased Order

• Pure Aluminum Quality Excellent; Contingent Quantity to be Ordered Soon

• Aluminum Alloy Quality Excellent, Vendor Responsive; Expected to Complete Successfully; Schedule has ~8 months slack
