Real Manufacturing and Trade Inventories (INVCMRMTSPL) was first constructed by the Federal Reserve Bank of St. Louis in June 2013. It is calculated using Real Manufacturing and Trade Inventories (INVHMRMT) (https://fred.stlouisfed.org/series/INVHMRMT) and Real Manufacturing and Trade Inventories (INVCMRMT) (https://fred.stlouisfed.org/series/INVCMRMT).

Before January 1997
lag1(INVHMRMT) = one observation earlier than current time period observation
INVHMRMT _PC = the growth rate of INVHMRMT
lead1(INVCMRMTSPL) = one observation later than current time period observation
INVHMRMT _PC = [INVHMRMT /lag1(INVHMRMT) –1]
INVCMRMTSPL= lead1(INVCMRMTSPL)/(1+ INVHMRMT _PC)

After December 1996
INVCMRMTSPL= INVCMRMT
