Accounting Policies [Abstract] |
Principles of Consolidation | Principles of Consolidation The accompanying Condensed Consolidated Financial Statements include the accounts of L3Harris Technologies, Inc. and its consolidated subsidiaries. As used in these notes to Condensed Consolidated Financial Statements (these “Notes”), the terms “L3Harris,” “Company,” “we,” “our” and “us” refer to L3Harris Technologies, Inc. and its consolidated subsidiaries. Intercompany transactions and accounts have been eliminated. The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, such interim financial statements do not include all information and footnotes necessary for a complete presentation of financial condition, results of operations, cash flows and equity in conformity with GAAP for annual financial statements and are not necessarily indicative of the results that may be expected for the full fiscal year or any subsequent period. In the opinion of management, these interim financial statements reflect all adjustments (including normal recurring adjustments) considered necessary for a fair presentation of our financial condition, results of operations, cash flows and equity for the periods presented therein.
Fiscal Year | Our fiscal year is based on a 52- or 53-week period ending on the Friday nearest December 31. The fiscal quarters ended October 3, 2025 (“third quarter 2025”) and September 27, 2024 (“third quarter 2024”) include 14 and 13 weeks, respectively. The year-to-date periods ended October 3, 2025 (“year to date 2025”) and September 27, 2024 (“year to date 2024”) both include 39 weeks.
Use of Estimates | Use of Estimates The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in the accompanying Condensed Consolidated Financial Statements and these Notes and related disclosures. These estimates and assumptions are based on experience and other information available prior to issuance of the accompanying Condensed Consolidated Financial Statements and these Notes. Materially different results can occur as circumstances change and additional information becomes known.
Reclassifications | Reclassifications The classification of certain prior year amounts have been adjusted in our Condensed Consolidated Financial Statements and these Notes to conform to current year classifications.
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements Accounting pronouncements issued during third quarter 2025, but not yet adopted, are not expected to have a material impact on our
Earnings Per Share | EPS is calculated as net income attributable to common shareholders divided by our weighted-average number of basic or diluted common shares outstanding. Potential dilutive common shares primarily consist of employee stock options, restricted stock units (“RSUs”) and performance share units (“PSUs”).
Fair Value Measurements | Deferred Compensation Plans We sponsor certain non-qualified deferred compensation plans which are measured at fair value on a recurring basis in our Condensed Consolidated Balance Sheet. Deferred compensation plan assets represent diversified assets held in rabbi trusts, which include marketable equity and fixed income securities (Level 1) and corporate-owned life insurance (”COLI”) contracts measured at NAV. Liabilities represent participant balances in marketable equity securities (Level 1) and common/collective trusts (“CCTs”) and guaranteed investment contracts (“GICs”) measured at NAV based on participant designed investment options.
