About 73% of Safeway’s stock was tendered.

SSI Holdings, formed by Kohlberg Kravis Roberts & Co. to acquire Safeway Stores, said its subsidiary, SSI Acquisition, had purchased 45 million shares of the common stock that were tendered as of Sept. 6. That completed the first phase of KKR’s $4.25-billion leveraged buyout. Shareholders of remaining Safeway shares will receive debentures with a market value of $61.60 and a warrant valued at $7.40 that entitles the holder to buy stock in the new company that will own Safeway.
