What Form N-PORT discloses, and what it withholds

Business development companies do not file Form N-PORT. Rule 30b1-9 applies to registered management investment companies and to exchange-traded funds organised as unit investment trusts, excluding money market funds and small business investment companies registered on Form N-5.

the dates

in forceReports are filed no later than 60 days after the end of a fund’s fiscal quarter. Only the report for the third month of that quarter is made public, upon filing.
28 August 2024Release IC-35308 adopts monthly filing within 30 days and monthly public availability with a 60-day lag. Published 11 September 2024, 89 FR 73764.
16 April 2025Release IC-35538 delays those amendments to 17 November 2027 for fund groups with $1bn or more in net assets, and to 18 May 2028 for smaller groups.
18 February 2026Release IC-35962 proposes to extend the filing deadline to 45 days and to restore quarterly publication. The comment period closed on 24 April 2026; as of our last check of the Commission’s rulemaking activity, no final rule had been adopted.

What becomes machine readable

Structured XML, position by position: issuer name and LEI, CUSIP and at least one further identifier, balance, currency, value in dollars, share of net assets, asset type — the list includes loan — restricted status, the ASC 820 level, and for debt the maturity, coupon and default status.

granularity · Position level, public once per quarter, for the third month of the fiscal quarter, up to 60 days after that quarter ends.

What stays out of reach

No business development company files it — so none of the large listed US private credit vehicles appear. The first and second months of each quarter stay non-public, as does the liquidity classification for every month. The monthly-public regime adopted in 2024 has never taken effect and may never do so.

What it changes for the measurement

This is where the declared fair value level and the CUSIP flag come from. It is also why the two sources cannot simply be merged: the funds filing N-PORT and the funds filing a Schedule of Investments are overlapping but different populations of lenders, holding the same loans. The level is used as an attribute of the tranche, never as a substitute for a reported price.
