Annual transactions computed as gross investment in nonresidential structures of property and casualty insurance companies plus one half of gross investment in nonresidential structures of other insurance (unpublished BEA data). Annual transactions are converted to seasonally adjusted quarterly transactions by calculating the ratio of the above series, to NIPA, Table 1.1.5 Gross Domestic Product, line 10, Private domestic, Nonresidential, Structures (annual); multiplied by line 10, Private domestic, Nonresidential, Structures (quarterly). Unadjusted transactions are calculated as transactions at a seasonally adjusted annual rate divided by 4. Series has no levels.
