SEMI lowers January, February book-to-bill figures
By Ann Steffora Mutschler, Senior Editor -- EDN, April 16, 2007
San Jose-based semiconductor manufacturing equipment industry association SEMI announced late Friday that corrections have been made to its January and February book-to-bill reports.
SEMI said that data in the original release was compiled by David Powell Inc., an independent financial services firm, without audit from data submitted directly by the participants, and a data input error was discovered in a review of the February book-to-bill report.
Figures for January now show the three-month average for bookings was $1.45 billion, with billings at $1.45 billion, and a ratio of 1.00, compared to the previous January bookings of $1.67 billion, billings of $1.6 billion and a ratio of 1.04.
Corrected figures for February show the three-month average for bookings was $1.4 billion, with billings at $1.43 billion, and a ratio of 0.98, compared to previously-reported February bookings of $1.65 billion, billings of $1.58 billion and a ratio of 1.05.
The SEMI book-to-bill is a ratio of three-month moving averages of worldwide bookings and billings for North American-based semiconductor equipment manufacturers. Billings and bookings figures are in millions of U.S. dollars.
SEMI noted that additional processes have been implemented to catch such errors before publication.
