The $0.5 million increase in the provision for credit losses was attributable to the increases in the Working Capital Loans and CVG portfolios of $0.3 million and $0.2 million, respectively, for the three-month period ended June 30, 2019 as compared to the three-month period ended June 30, 2018.
Total portfolio net charge-offs were $4.9 million for the three-month period ended June 30, 2019, compared to $4.3 million for the corresponding period in 2018. The increase incharge-off rate is primarily due to the ongoing seasoning of the Equipment Finance portfolio as reflected in the mix of origination vintages and the mix of credit profiles, as well as the increased portfolio balances. Total portfolio net charge-offs as an annualized percentage of average total finance receivables increased to 1.88% during the three-month period ended June 30, 2019, from 1.84% for the corresponding period in 2018. The allowance for credit losses increased to approximately $16.8 million at June 30, 2019, an increase of $0.7 million from $16.1 million at December 31, 2018.
