It stands for other comprehensive income; the income (revenue and expense items) that results from changes in net assets that involve no transactions with owners, and hence are not displayed on the income statement. Examples of other comprehensive income include: 1) long-lived assets that are measured based on the revaluation model (rather than the cost model), and 2) unrealized gains/ losses on derivatives contracts used for hedging purposes, and 3) unrealized holding gains/ losses on available-for-sale securities. These income items bypass the income statement and are treated as other comprehensive income.

Other comprehensive income (OCI) constitutes a part of comprehensive income, as:

Comprehensive income = net income + other comprehensive income

CI = NI + OCI
