| Bar Chart and Performance Table [Heading] | PAST FUND PERFORMANCE: |
| Performance Narrative [Text Block] | The information in the bar chart and table below provides some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year for the periods indicated and by showing how the Fund’s average annual returns over time compare with those of a broad-based securities market index, the Bloomberg Global Aggregate Index, as well as an additional market index with characteristics that are similar to those of the Fund, the J.P. Morgan Corporate EMBI Broad Diversified Composite Index. After‑tax returns for the Fund are calculated using the highest individual Federal marginal income tax rates for each year and do not reflect the impact of state and local taxes. Actual after‑tax returns depend on an investor’s tax situation and may differ from those shown. They also may not be relevant to investors who hold Fund shares through tax‑deferred arrangements, such as 401(k) plans or individual retirement accounts. The returns “After Taxes on Distributions and Sale of Fund Shares” may be higher than the other return figures because they include the effect of a tax benefit an investor may receive from the capital losses that may have been incurred by an investor in connection with the sale of Fund shares. Updated performance information for the Fund may be found on the Fund’s internet site at payden.com. Past performance (before and after taxes) is no guarantee of future results.
