A share-lending quote prices the temporary use of a security; it does not promise that the whole portfolio will earn that rate all year. The new exposure begins when shares leave ordinary custody under a lending agreement: an income opportunity arrives alongside different rights and protections.[3][5]

Program terms checked September 23, 2026. The rate, balance, and borrowing period below are hypothetical.

Fully paid lending lets a brokerage customer lend securities already paid for. This article follows Fidelity's U.S. program, with Schwab as a comparison; contracts differ. Fidelity's arrangement is separate from the reuse of securities under a margin borrowing agreement.[2] My working view for an income budget is conservative: treat lending receipts as an intermittent supplement until actual borrowing history supports something steadier.

The quoted rate needs borrowed days

Suppose $10,000 of eligible shares, held within an otherwise qualifying account, is borrowed at a 6% annualized rate payable to the customer. Keep both the share value and rate constant for 30 days. Using the 360-day convention in Fidelity's published illustration, the gross lending income is $50:[1]

$10,000 × 0.06 × 30 ÷ 360 = $50.

These are assumptions, not an available offer. The customer rate is already after the broker's share of lending revenue; the calculation remains before the customer's taxes. Schwab's explanation distinguishes the fee collected from borrowers from the portion passed to the account holder, a useful reminder to identify which rate a screen is displaying.[5]

Now let borrowing demand disappear. The shares are returned and remain unborrowed for the rest of the year. The lending receipt stays at $50, even though the investor keeps owning the investment. That is the first branch of the scenario: the annualized quote was accurate, while an annual income forecast based on uninterrupted lending would have been wrong.

Fidelity does not promise to borrow enrolled securities, and its rates can change. Schwab likewise says it can end a loan at any time.[1][5] Enrollment supplies permission; demand supplies paid days. A statement showing the actual borrowed balance and duration therefore carries more information than the most attractive rate seen during the month.

A dividend date changes the comparison

In the second branch, the loan remains open across a dividend record date. Fidelity says the customer receives a substitute cash payment in place of the issuer's dividend.[1] Equal cash arriving in the account need not mean equal cash retained after tax.

For a U.S. taxable account, the distinction can matter when the original dividend would have qualified for preferential treatment. IRS Publication 550 distinguishes substitute payments from qualifying dividends and explains their reporting.[4] The relevant comparison is after-tax lending income plus any after-tax broker adjustment, less the additional tax attributable to the substitution. Tax status and the particular distribution determine the result; the $50 illustration alone cannot settle it.

There is a substantial counterweight here. Fidelity's fact sheet describes an annual credit adjustment for qualifying substitute distributions in participating taxable accounts, while warning that the adjustment may not eliminate the entire additional tax burden.[2] Ignoring that credit would make the program look worse than its stated terms. Assuming it makes every investor whole would go too far in the other direction.

Voting follows a separate calendar. Fidelity says a shareholder who wants to vote should recall shares before the proxy record date; a meeting date is too late a planning anchor.[1] A lending return can consequently be attractive in cash terms yet conflict with the investor's reason for holding the shares.

When collateral has to do the work

The adverse branch is broker default. Fidelity states that loaned shares lack Securities Investor Protection Corporation coverage and that it supplies collateral worth at least 100% of the loan value.[1] Its fact sheet identifies Fidelity as the counterparty, with collateral held at an independent custodial bank and adjusted daily. Following a contractual default, the customer can seek that collateral under the applicable agreements.[2]

That structure provides a real recovery mechanism. It also changes the question from whether shares appear on a portfolio screen to what assets the customer can obtain, through which procedure, if the borrower fails. FINRA's rule requires firms to warn that collateral may be the only source of satisfaction if securities are not returned; it also requires disclosure of collateral risks.[3]

A daily valuation is a snapshot. As a scenario inference, if replacement shares become more expensive before collateral can be accessed and used, the last collateral balance may buy fewer shares. This is a timing and recovery exposure, not a prediction that Fidelity will default. Nor does collateral protect against an ordinary fall in the stock: the investor retains the investment's market exposure.[5]

What would make the income dependable?

The strongest case for lending is straightforward: an investor keeps an investment they intended to own, earns additional cash while it is borrowed, and can sell or request its return. Schwab describes that flexibility in its program terms.[5] For someone with persistent borrowing demand, acceptable tax treatment, and no immediate voting requirement, the supplement can be worthwhile.

The falsifier for this article's budgeting view would be a full year of account statements showing sustained lending of the assumed balance, with realized receipts after attributable taxes and adjustments supporting the planned income. That would defeat the intermittent-income assumption for that portfolio and period. It would leave the contractual default exposure intact.

The next evidence arrives through ordinary account events:

• At the next monthly lending statement: reconcile borrowed balances, daily rates, and paid days with cash credited. Separate a rate reduction from shares no longer being borrowed.[2]
• When the issuer announces its next dividend or proxy record date: compare the value of continued lending with the tax consequences or need to recall shares for voting.[3][4]
• At the next collateral adjustment or agreement revision: check the collateral held, who controls it, and the stated process for obtaining it following default. A larger income estimate cannot answer those recovery questions.[2][3]
