	 General Provisions

five (5) or more, the preceding decimal place shall be raised to the next higher figure. 
 Each quotient shall be
rounded to the nearest ten thousandth (4 decimals). If the next succeeding place is five (5) or more, the preceding decimal place shall be raised to the next higher figure. 

The final factor shall be rounded to the nearest ten thousandth (4 decimals). 

The final price shall be rounded to the nearest whole number (0.5 or more rounded to 1). 

 

	 5.2
	 Substitution of Indexes for Airframe Price Revision Formula 

If;

	 	 (ii)

Revision Formula to combine the successive utilization of the original Labor Index or Material Index (as the case may be) and of the Substitute Index.
