Through 2008:Q1, unadjusted transactions are obtained on a monthly basis from FR Board, CM, Publicly Offered Corporate Bonds and Notes report, Domestic, IB. Level is obtained by adding three months' transactions to the preceding level. Beginning 2008:Q2, unadjusted transactions are held constant at the 2008:Q1 value due to discontinuation of the data source. Data for the most recent ten years show no significant seasonality.
