G17: Seasonal Factors for auto and truck production have been reestimated

Seasonal factors for auto and truck production have been revised. These factors are based on production data through April 2015 and were revised back to January 1996. The seasonal factors explicitly incorporate the holiday schedule for the vehicle assembly lines. The AFL-CIO's current collective bargaining agreements with domestic manufacturers, however, expire at the end of the third quarter of 2015. Factors for the fourth quarter of 2015 and for 2016 were estimated based on the holiday schedule in place over the past three years. Once the new agreements are finalized, the seasonal factors will be updated to reflect the agreed-upon holiday schedule over the terms of the contracts.
