International Lease restated its 1983 earnings.

Beverly Hills-based International Lease Finance said it reduced its earnings by $903,000 for the year ended Nov. 30, 1983. The reduction was caused by changes in the investment tax credit, which required a reduction in the credit to 8% from 10% of investments, the company said. The reduction cut net income to $10.9 million for 1983. It also caused “certain adjustments� to fiscal 1984, which resulted in net income of $13.4 million on sales of $61.7 million.
