Shield states that his return expectation for a portfolio of corporate bonds is 3%–6% per annum over a 10-year period. Edge questions whether that level of return is sufficient for Derran and offers the following suggestions with respect to increasing portfolio returns.
Suggestion 1 Overweight the portfolio with bonds of highly leveraged companies because their yields generally exceed those of companies that have lower debt levels.
Suggestion 2 Consider using inverse floaters and fixed-rate receiver swaps in order to position the portfolio to benefit from any decline in interest rates over the 10-year market cycle.
Suggestion 3 Enter into repurchase agreements and securities lending transactions with counterparties that are conservatively leveraged.

解释：
Adding bonds of highly leveraged companies does not involve the use of leverage. The following methods of leverage may be used to increase portfolio returns relative to an unleveraged portfolio: (1) futures contracts, (2) swap agreements, (3) structured financial instruments, (4) repurchase agreements, and (5) securities lending. Each of these methods adds leverage to an unleveraged portfolio, including, as in this example, an unleveraged portfolio of bonds from highly leveraged companies.
如题，请问如何通过security lending进行leverage？
